Description

この発明は、２つを反転して組み合わせることで盛土用発泡樹脂ブロックを構成する盛土用発泡樹脂ブロック体に関し、特に、地下水の上昇や排水量の多い場所で使用しても浮力による影響を抑えることができるようにしたものである。   The present invention relates to a foamed resin block body for embankment that constitutes a foamed resin block for embankment by inverting and combining the two, and particularly suppresses the influence of buoyancy even when used in places where there is a large amount of groundwater rise or drainage. It is made to be able to.

従来より、軟弱地盤、急傾斜地などの土木工事においては、土砂などにより盛土を形成するのに代えて、発泡ポリスチレンなどの合成樹脂発泡体を使用した盛土用発泡樹脂ブロックによって、盛土を構築する盛土代替え工法が行われている。   Conventionally, in civil engineering work such as soft ground and steep slopes, embankments are constructed by using foamed resin blocks for embankment using synthetic resin foams such as foamed polystyrene instead of forming embankments with earth and sand. Alternative construction methods are being implemented.

このような盛土代替え工法では、盛土用発泡樹脂ブロックを用いることで、その軽量性、自立性、耐水性、断熱性、加工性などの優れた特性を活用することができる。   In such an embankment replacement method, by using the foamed resin block for embankment, it is possible to utilize excellent characteristics such as lightness, self-supporting property, water resistance, heat insulation, and workability.

しかしながら、この盛土用発泡樹脂ブロックの材料として用いられる発泡ポリスチレンなどの合成樹脂発泡体は、水より密度が低く軽量で、耐水性を有しているため、地下水の水位が上昇した場合や、季節的な降雨や洪水などで冠水した場合には、盛土用発泡樹脂ブロックに大きな浮力が生じて不安定になり、本来の自立性を保持できなくなる。   However, synthetic resin foams such as expanded polystyrene used as the material for the foamed resin block for embankment are lighter in density and lighter than water, and have water resistance. When flooded due to typical rainfall or flooding, the foamed resin block for embankment becomes unstable due to large buoyancy, and the original independence cannot be maintained.

そこで、このような浮力の影響を抑えるために種々の提案がなされている。   Therefore, various proposals have been made to suppress the influence of such buoyancy.

例えば、盛土用発泡樹脂ブロックに貫通孔を設けて、その部分にパイプなどの部材やコンクリートなどの充填材を入れて、段積みを強固にすることが行われているが、施工面において複雑になったり、施工時間が増大するばかりか、重量の増加につながり、盛土用発泡樹脂ブロックを使用する効果が半減してしまう。   For example, a through-hole is provided in a foamed resin block for embankment, and a member such as a pipe or a filler such as concrete is put in that part to strengthen the stacking. Not only will the construction time increase, it will lead to an increase in weight, and the effect of using the foamed resin block for embankment will be halved.

一方、盛土用発泡樹脂ブロック自体の構造を工夫したものとして、例えば特許文献1には、図９（ａ）の底面図および（ｂ）の断面図に示すように、発泡樹脂板１に複数の突起部２を空間部３をあけて設けるとともに、空間部３を外部に開放するようにしてあり、空間部３を導水路および排水路とし、空間部３内に水を導入することで浮力を小さくする一方、水位の低下により排水することで軽量性を回復させるようにしている。   On the other hand, as a devised structure of the foamed resin block itself for embankment, for example, in Patent Document 1, as shown in a bottom view of FIG. 9A and a cross-sectional view of FIG. The projecting portion 2 is provided with the space portion 3 open, and the space portion 3 is opened to the outside. The space portion 3 serves as a water conduit and a drainage channel, and water is introduced into the space portion 3 to increase buoyancy. On the other hand, the lightness is restored by draining the water level as it is reduced.

また、特許文献２には、図１０の斜視図に示すように、上下面が正方形のブロック４の中央部に９つの円形の貫通孔５を、側面に３つの半円の側面貫通凹部６を、４隅に４分の１円の４隅貫通凹部７をそれぞれ形成するとともに、下面部に横溝８を、上面部に突起９を形成してあり、空隙部となるそれぞれの貫通部５、６、７を排水路として機能させることで効率よく排水し、地下水の上昇時にもブロックが浮き上がらず、水位が下がると本来の機能を回復できるようにしている。   Further, in Patent Document 2, as shown in the perspective view of FIG. 10, nine circular through holes 5 are provided at the center of a block 4 whose upper and lower surfaces are square, and three semicircular side through recesses 6 are provided on the side. A four-corner four-corner through recess 7 is formed in each of the four corners, a lateral groove 8 is formed in the lower surface portion, and a protrusion 9 is formed in the upper surface portion. , 7 is allowed to function as a drainage channel so that the block can not be lifted even when the groundwater rises, and the original function can be restored when the water level drops.

さらに、特許文献３には、図１１（ａ）の上面斜視図および（ｂ）の底面斜視図に示すように、下面が開放され上面が天板部１０で略封止された箱状体に形成され、内部に多数の水溜室１１を区画形成し、多数の水溜室１１を箱状体の中心を通る仕切壁１２で４つの群に分割し、仕切壁１２および外側壁のスリット１３で各群ごとに注排水可能とし、さらに、天板部１０には溝１４および開口部１５が多数配置されており、外壁部および仕切壁のスリット１３で盛土などの表面から浸透した水を各郡ごとに水溜室１１に注水し、天板部１０の開口部１５で冠水あるいは水位低下の水位に倣って水を速やかに注水し、あるいは排水するようにし、浮力を十分に抑制し、排水能力に優れるようにしている。   Further, in Patent Document 3, as shown in a top perspective view of FIG. 11A and a bottom perspective view of FIG. 11B, a box-shaped body whose bottom surface is opened and whose top surface is substantially sealed by the top plate 10 is disclosed. A plurality of water storage chambers 11 are formed in the interior, and the plurality of water storage chambers 11 are divided into four groups by a partition wall 12 passing through the center of the box-shaped body, and each of the partition walls 12 and the slits 13 on the outer wall is divided. Each group can be poured and drained, and the top plate 10 is provided with a large number of grooves 14 and openings 15. Water that has permeated from the surface of the embankment or the like through the slits 13 of the outer wall and the partition wall for each group Water is poured into the water reservoir chamber 11 and water is quickly poured or drained at the opening 15 of the top plate 10 in accordance with the submerged water level or the water level lowering, and the buoyancy is sufficiently suppressed and the drainage capacity is excellent. I am doing so.

ところが、特許文献１の盛土材では、２つの盛土材を発泡樹脂板１，１が上下に配置されるように組み合わせて１つのユニットとして使用すると、突起部２，２間の空隙部３を介して水の流入や流出が起こるものの、上下面が塞がれていることから急激な水位上昇などの場合には、水の流入が円滑になされず、大きな浮力が作用するという問題がある。   However, in the embankment material of Patent Document 1, when two embedding materials are combined so that the foamed resin plates 1 and 1 are arranged up and down and used as one unit, the gap 3 between the projections 2 and 2 is interposed. However, in the case of a sudden rise in water level due to the fact that the upper and lower surfaces are blocked, there is a problem that the inflow of water is not smooth and large buoyancy acts.

また、特許文献２の盛土用発泡樹脂ブロックでは、上下方向には、貫通孔５、側面貫通凹部６、４隅貫通凹部７が形成されていることから水の流入、流出が円滑に行われるものの、側方への水の流入、流出が行われにくく、しかも施工時に多数の貫通孔５などに足を取られるといった問題もある。   Moreover, in the foaming resin block for embankment of patent document 2, since the through-hole 5, the side-surface through recessed part 6, and the 4 corner through recessed part 7 are formed in the up-down direction, inflow and outflow of water are performed smoothly. In addition, there is a problem that the inflow and outflow of water to the side are difficult to be performed, and that a large number of through-holes 5 are taken during construction.

さらに、特許文献３の発泡樹脂成形体では、水の流入、流出を仕切壁１２などのスリット１３と天板部１０の開口部１５で行うようにしているが、いずれも比較的小さく、急激な冠水や水位の上昇が起こった場合に注水や排水の抵抗となり、大きな浮力が作用したり、排水に時間がかかるという問題がある。   Furthermore, in the foamed resin molded body of Patent Document 3, the inflow and outflow of water are performed by the slit 13 such as the partition wall 12 and the opening 15 of the top plate part 10, but both are relatively small and abrupt. When flooding or water level rises, there is a problem of water injection or drainage resistance, and there is a problem that large buoyancy acts or drainage takes time.

一方、発泡樹脂ブロックの成形性についてみると、特許文献１〜３（５）のいずれの場合も、水が流入する空隙部の形状は比較的単純であってもブロックに残された荷重を支持する部分は複雑な形状とされ、金型製作に多大なコストを要するという問題がある。   On the other hand, regarding the moldability of the foamed resin block, in any case of Patent Documents 1 to 3 (5), the load remaining in the block is supported even if the shape of the void into which water flows is relatively simple. The part to be made has a complicated shape, and there is a problem that a great deal of cost is required to manufacture the mold.

また、浮力の影響を抑えるため、貫通孔などを大きくすると、敷設の際ブロックを積み重ねた場合の支持部分の接触面積が小さくなり、圧縮強度が小さくなってしまうという問題もある。   In addition, if the through-holes and the like are enlarged in order to suppress the influence of buoyancy, there is a problem that the contact area of the support portion when the blocks are stacked at the time of laying is reduced, and the compressive strength is reduced.

この発明は、上記従来技術の問題点に鑑みてなされたもので、上下方向および側方のいずれへも注水および排水が円滑にでき、しかも大きな空隙部を確保できるとともに、圧縮強度が大きく、荷重を均一に掛けることができ、構造が簡単で成形し易い盛土用発泡樹脂ブロック体を提供しようとするものである。   This invention has been made in view of the above-mentioned problems of the prior art, and can smoothly inject and drain water in both the vertical direction and the lateral direction, and can secure a large gap, and has a high compressive strength, a load It is intended to provide a foamed resin block body for embankment that can be applied uniformly, has a simple structure, and is easy to mold.

そこで、盛土用発泡樹脂ブロック体について鋭意検討を重ねた結果、浮力については、上下方向および側方のいずれにも円滑な水の流通性を確保する必要があり、空隙部は形状にかかわらず大きさが確保できれば良いのに対し、ブロックに残される支持部は、荷重を均一に支持でき、しかも圧縮強度をできるだけ小さな断面積で支持できる一定に配列される形状にすることが有効であることを見出し、この発明を完成したものである。   Therefore, as a result of intensive studies on the foamed resin block body for embankment, it is necessary to ensure smooth water flow in both the vertical and lateral directions, and the gap is large regardless of the shape. However, it is effective that the support portion remaining in the block has a shape that is uniformly arranged so that the load can be uniformly supported and the compressive strength can be supported with the smallest possible cross-sectional area. The headline and the present invention have been completed.

すなわち、上記課題を解決するため、この発明の請求項１記載の盛土用発泡樹脂ブロック体は、互いを反転組み合わせて盛土用発泡樹脂ブロックを構成する発泡樹脂ブロック体であって、発泡樹脂板に一定の配列で複数の支柱部を突出させて設け、この支柱部が設けられない前記発泡樹脂板部分に一定配列で複数の貫通部を設けてなることを特徴とするものである。   That is, in order to solve the above-mentioned problem, the foamed resin block body for embankment according to claim 1 of the present invention is a foamed resin block body that constitutes a foamed resin block body for embankment by reversing and combining each other. A plurality of support portions are provided so as to protrude in a fixed arrangement, and a plurality of through portions are provided in a fixed arrangement in the foamed resin plate portion where the support portions are not provided.

この盛土用発泡樹脂ブロック体によれば、発泡樹脂板に一定の配列で突出させて設けた複数の支柱部同士を突き合わせてブロックとすることで、荷重を均一に支持して圧縮強度を高めるようにし、浮力に対して発泡樹脂板の一方側では、支柱部の側方を水の注排水路とし、他方側では、発泡樹脂板に一定配列で複数設けた貫通部を水の注排水路とすることで、急激な水位上昇や冠水にも対応できるようにしている。   According to the foamed resin block body for embankment, the load is uniformly supported and the compressive strength is increased by making a block by abutting a plurality of support portions provided by protruding the foamed resin plate in a fixed arrangement. On one side of the foamed resin plate with respect to buoyancy, the side of the support column is a water pouring / draining channel, and on the other side, a plurality of penetrating portions provided in a fixed arrangement on the foaming resin plate are arranged as a water pouring / draining channel By doing so, it is possible to cope with sudden water level rise and flooding.

The opening is provided at the outer end of the foamed resin plate.

この盛土用発泡樹脂ブロック体によれば、浮力に対して発泡樹脂板の他方側では、発泡樹脂板に一定配列で複数設けた貫通部と連通させて形成した溝部を水の注排水路とすることで、一層注排水が円滑となり、急激な水位上昇や冠水にも対応できるようにしている。   According to the foamed resin block body for embankment, on the other side of the foamed resin plate with respect to buoyancy, a groove portion formed by communicating with a plurality of through portions provided in a fixed arrangement on the foamed resin plate is used as a water pouring / draining channel. As a result, the drainage becomes even smoother, and it is possible to cope with a sudden rise in water level and flooding.

さらに、この発明の請求項３記載の盛土用発泡樹脂ブロック体は、請求項１または２記載の構成に加え、前記支柱部に、互いに嵌合連結可能な嵌合凸部と嵌合凹部とを、前記反転組み合わせ可能に配置して設けたことを特徴とするものである。   Furthermore, in the foamed resin block body for embankment according to claim 3 of the present invention, in addition to the configuration according to claim 1 or 2, a fitting convex portion and a fitting concave portion that can be fitted and connected to each other are provided on the support column portion. , And arranged so as to be able to be reversed and combined.

この盛土用発泡樹脂ブロック体によれば、前記支柱部に設けた互いに嵌合連結可能な嵌合凸部と嵌合凹部とを反転組み合わせ可能に配置することで、ずれを防止して安定性を向上できるとともに、一層強固なブロックにできるようにしている。   According to this foamed resin block body for embankment, by disposing the fitting convex portion and the fitting concave portion, which can be fitted and connected to each other, so as to be able to be reversed and combined, the shift is prevented and the stability is improved. It is possible to improve and make it a stronger block.

この発明の請求項１記載の盛土用発泡樹脂ブロック体によれば、発泡樹脂板に一定の配列で突出させて設けた複数の支柱部同士を突き合わせてブロックとしたので、荷重を均一に支持して圧縮強度を高めることができる。   According to the foamed resin block body for embankment according to claim 1 of the present invention, since the plurality of support portions provided by projecting in a fixed arrangement on the foamed resin plate are abutted to form a block, the load is uniformly supported. The compression strength can be increased.

また、浮力に対して発泡樹脂板の一方側では、支柱部の側方を水の注排水路とし、他方側では、発泡樹脂板に一定配列で複数設けた貫通部を水の注排水路としたので、急激な水位上昇や冠水にも対しても円滑に水を注排水することができ、浮力を極力抑えることができる。   In addition, on one side of the foamed resin plate with respect to buoyancy, the side of the column part is a water pouring / draining channel, and on the other side, a plurality of penetrating parts provided in a fixed arrangement on the foaming resin plate are arranged as a water pouring / draining channel. Therefore, water can be poured and drained smoothly even against sudden water level rise and flooding, and buoyancy can be suppressed as much as possible.

さらに、この発明の請求項２記載の盛土用発泡樹脂ブロック体によれば、浮力に対して発泡樹脂板の他方側では、発泡樹脂板に一定配列で複数設けた貫通部と連通させて形成した溝部を水の注排水路とすることができ、一層注排水が円滑となり、急激な水位上昇や冠水にも対応することができる。   Furthermore, according to the foamed resin block body for embankment according to claim 2 of the present invention, the other side of the foamed resin plate with respect to buoyancy is formed in communication with a plurality of through portions provided in a fixed arrangement on the foamed resin plate.

以下、この発明の実施の形態について図面を参照して詳細に説明する。
図１および図２は、この発明の盛土用発泡樹脂ブロック体の一実施の形態にかかり、図１（ａ）は上方から見た斜視図、（ｂ）は下方から見た斜視図、図２（ａ）は背面および左右側面と同一の正面図、（ｂ）は平面図、（ｃ）は底面図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 and 2 relate to one embodiment of a foamed resin block body for embankment of the present invention, FIG. 1 (a) is a perspective view seen from above, (b) is a perspective view seen from below, FIG. (A) is the same front view as the back and left and right sides, (b) is a plan view, and (c) is a bottom view.

この盛土用発泡樹脂ブロック体は、軟弱地盤などで盛土を行う場合に、土や土砂などに代えて使用される発泡ポリスチレンなどの合成樹脂発泡体からなる盛土用ブロック体であって、同一形状のブロック体を反転して下側に配置して重ねることで一つの盛土用ブロックとして使用するもので、例えば縦横の大きさが１ｍとされる。   This foamed resin block body for embankment is a block body for embankment made of synthetic resin foam such as expanded polystyrene used in place of soil or earth and sand when embankment is performed on soft ground, etc. The block body is inverted and arranged on the lower side and overlapped to be used as one embankment block. For example, the vertical and horizontal sizes are 1 m.

この盛土用発泡樹脂ブロック体２０は、平面形状が矩形、例えば正方形の発泡樹脂板２１に一定の配列で複数の支柱部２２が突出させて一体に成形されて設けられ、例えば中央部に９個の円錐台形状の中央支柱部２２ａが一定の間隔をあけて設けられ、側面部に平断面が半分の側面支柱部２２ｂがそれぞれ３個ずつ一定の間隔をあけて設けられ、四隅部に平断面が４分の一の隅部支柱部２２ｃがそれぞれ１個ずつ設けられ、各支柱部２２ａ，２２ｂ，２２ｃの中心が正方形の外形線および正方形を４等分する線による格子の交差点に配置されて一定の配列となっている。   The foamed resin block body 20 for embankment is provided by integrally molding a plurality of supporting column portions 22 in a fixed arrangement on a foamed resin plate 21 having a rectangular planar shape, for example, a square shape, for example, nine in the central portion. The central columnar portion 22a having a truncated cone shape is provided with a certain interval, and three side column portions 22b each having a half flat cross section are provided with a certain interval on the side surface, and the flat cross section is provided at the four corners. Is provided with one quarter corner support 22c, and the center of each support 22a, 22b, 22c is arranged at the intersection of the grid with a square outline and a line dividing the square into four equal parts. It is a fixed array.

なお、これら支柱部２２の一定の配列は、盛土用発泡樹脂ブロック体２０を左右・前後に並べた場合でも隣接する盛土用発泡樹脂ブロック体２０同士を含めて一定の配列が維持できるようにしてある。   In addition, the fixed arrangement | sequence of these support | pillar parts 22 is maintained so that fixed foaming resin block bodies 20 adjacent to each other can be maintained even when the foaming resin block bodies 20 for embankment are arranged side by side, front and back. is there.

この支柱部２２の大きさは、発泡樹脂板２１の正方形と発泡樹脂板２１および支柱部２２の高さ（総高さ）で作られる立体に対して、空隙率が６０〜６５％程度となるように、円錐台形の大径部および小径部の大きさが定められ、例えば正方形の1辺を１ｍ、総高さを２５０ｍｍ（発泡樹脂板の高さ４５ｍｍ、支柱部の高さ２０５ｍｍ）とし、支柱部の円錐台形の大径部の直径を１６０ｍｍ、小径部の直径を１５０ｍｍとする。   The size of the support column 22 is about 60 to 65% of the solid made of the square of the foam resin plate 21 and the height (total height) of the foam resin plate 21 and the support column 22. Thus, the size of the large-diameter part and the small-diameter part of the frustoconical shape is determined. For example, one side of the square is 1 m, the total height is 250 mm (the height of the foamed resin plate is 45 mm, the height of the support column is 205 mm), The diameter of the large-diameter portion of the truncated cone shape of the support column is 160 mm, and the diameter of the small-diameter portion is 150 mm.

空隙率が６０％より低い場合、排水性が悪くなる傾向があり、また空隙率が６５％より高い場合、冠水時においてブロックが所定位置から動いてしまう傾向にある。   When the porosity is lower than 60%, drainage tends to be poor, and when the porosity is higher than 65%, the block tends to move from a predetermined position during flooding.

このような盛土用発泡樹脂ブロック体２０を構成する発泡樹脂板２１および一体に成形される支柱部２２は、例えば発泡ポリスチレン、発泡ポリプロピレン、発泡ポリエチレン、発泡ポリウレタン等の合成樹脂の発泡体が用いられて成形されるが、成形性、加工性、コスト面で発泡ポリスチレンが優位となる。   The foamed resin plate 21 constituting the embankment foamed resin block body 20 and the integrally formed support column 22 are, for example, synthetic resin foams such as foamed polystyrene, foamed polypropylene, foamed polyethylene, and foamed polyurethane. However, expanded polystyrene is superior in terms of moldability, processability, and cost.

そして、このような合成樹脂発泡体の密度は、盛土用発泡樹脂ブロック体２０の空隙率や必要な圧縮強度により適宜設定すれば良く、３０〜６０kg/m3、好ましくは４０〜５０kg/m3であり、３０kg/m3より小さいと、圧縮強度が不足し、６０kg/m3を越えると、樹脂の使用量が増加し、重量の増大を招くとともに、コストも増大する。   And the density of such a synthetic resin foam should just be set suitably with the porosity of the foamed resin block body 20 for embankments, and required compressive strength, and is 30-60 kg / m3, Preferably it is 40-50 kg / m3. If it is less than 30 kg / m 3, the compressive strength is insufficient, and if it exceeds 60 kg / m 3, the amount of resin used increases, resulting in an increase in weight and cost.

また、この盛土用発泡樹脂ブロック体２０では、発泡樹脂板２１に表裏を貫通する複数の貫通部２３が一定配列で支柱部２２と重ならない部分に設けてある。   Moreover, in this foamed resin block body 20 for embankment, the several penetration part 23 which penetrates the front and back in the foamed resin board 21 is provided in the part which does not overlap with the support | pillar part 22 by fixed arrangement | sequence.

これら貫通部２３は、例えば円形の貫通孔２３aで構成され、支柱部２２（２２ａ、２２ｂ、２２ｃ）の中心同士を結ぶ線の交差点の１６ヶ所に形成することで支柱部２２と重ならないようにしてあり、支柱部２２の中心に対しては千鳥状に配置されて一定の配列となっている。   These through-holes 23 are constituted by, for example, circular through-holes 23a, and are formed at 16 intersections of lines connecting the centers of the columns 22 (22a, 22b, 22c) so as not to overlap with the columns 22. It is arranged in a staggered manner with respect to the center of the support column 22 and has a fixed arrangement.

なお、この貫通部２３の一定の配列は、盛土用発泡樹脂ブロック体２０を左右・前後に並べた場合でも隣接する盛土用発泡樹脂ブロック体２０同士を含めて一定の配列が維持できるようにしてある。   In addition, the fixed arrangement of the through-holes 23 is such that the fixed arrangement including the adjacent foamed resin block bodies 20 for embankment can be maintained even when the foamed resin block bodies 20 for embankment are arranged side by side. is there.

これら貫通孔２３aの大きさは、全貫通孔２３aで上下方向の注排水が円滑にできる流路断面積が確保できれば良く、例えば上記寸法の盛土用発泡樹脂ブロック体（１ｍ×１ｍ×２５０ｍｍ）の場合、１つの貫通孔の直径を７０ｍｍとして１６個を互いに等間隔に形成する。   The size of these through-holes 23a only needs to ensure a flow passage cross-sectional area that allows smooth vertical pouring and drainage in all through-holes 23a. For example, the embedding foam resin block body (1 m × 1 m × 250 mm) having the above dimensions is used. In this case, the diameter of one through hole is 70 mm, and 16 are formed at equal intervals.

また、貫通孔２３ａの大きさは、ブロック体２０の上に作業員が載っても足を取られ難いものとし、上記の直径７０ｍｍとすることで、この条件を満たすものとなる。   The size of the through-hole 23a is such that it is difficult for a worker to step on the block body 20 and the above-mentioned diameter is 70 mm, which satisfies this condition.

さらに、この盛土用発泡樹脂ブロック体２０では、発泡樹脂板２１の支柱部２２と反対側の表面に、貫通部２３と連通する溝部２４が形成され、溝部２４の端が発泡樹脂板２１の外側端部で開口するように形成してあり、例えば矩形断面の溝２４aで構成される。   Further, in the foamed resin block body 20 for embankment, a groove portion 24 communicating with the through portion 23 is formed on the surface of the foamed resin plate 21 opposite to the support column portion 22, and the end of the groove portion 24 is outside the foamed resin plate 21. It is formed so as to open at the end, and is constituted by a groove 24a having a rectangular cross section, for example.

これにより、同一形状の盛土用発泡合成樹脂ブロック体２０を反転して下側に配置して重ねることで一つの盛土用発泡合成樹脂ブロック２０Ａとし、これを上下に積み重ねたり、通常の中実のブロックBを上に積み重ねる場合の重ね合わせ面の水の流通性をこの溝部２４によって確保する。   Thereby, the foamed synthetic resin block body 20 for the embankment having the same shape is inverted and arranged on the lower side to be stacked to form one foamed synthetic resin block 20A for the embankment, which can be stacked up and down, The groove portion 24 ensures the water flowability of the overlapping surface when the blocks B are stacked on top.

この溝部２４は、例えば発泡樹脂板２１の外形線と平行な格子状に配置され、縦横それぞれ４本の溝部２４が格子状に形成され、貫通部２３上に溝部２４の溝２４aの底面が位置するように形成することで、貫通部２３と溝部２４が連通するようにしてある。   For example, the groove portions 24 are arranged in a lattice shape parallel to the outline of the foamed resin plate 21, and four groove portions 24 are formed in a lattice shape in the vertical and horizontal directions, and the bottom surface of the groove 24 a of the groove portion 24 is positioned on the through portion 23. By forming in such a manner, the penetrating part 23 and the groove part 24 communicate with each other.

この溝部２４の大きさは、貫通部２３を介して発泡樹脂板２１の上面に来る水を側方に流したり、逆に発泡樹脂板２１の側方からの水を上面を介して貫通部２３に流すことができれば良く、例えば上記寸法の盛土用発泡樹脂ブロック体（１ｍ×１ｍ×２５０ｍｍ）の場合、貫通孔２３の直径と同一の幅７０ｍｍとされ、深さは１０ｍｍとして形成してある。   The size of the groove portion 24 is such that the water coming to the upper surface of the foamed resin plate 21 flows laterally through the through portion 23, or conversely, the water from the side of the foamed resin plate 21 flows through the upper surface of the through resin portion 21. For example, in the case of a foamed resin block body for embankment (1 m × 1 m × 250 mm) having the above dimensions, the width is set to 70 mm, which is the same as the diameter of the through hole 23, and the depth is set to 10 mm.

また、この盛土用発泡樹脂ブロック体２０では、同一形状の盛土用発泡樹脂ブロック体２０を反転して下側に配置してその上にこの盛土用発泡樹脂ブロック体２０を重ねることで一つの盛土用発泡樹脂ブロック（盛土用ブロック）２０Ａとして使用する場合のずれを防止するため、図２に示すように、中央部の中央支柱部２２ａの先端に嵌合連結部２５が設けられ、嵌合凸部２５ａと嵌合凹部２５ｂとで構成される。   Moreover, in this foaming resin block body 20 for embankment, it is one embankment by inverting the foaming resin block body 20 for embankment of the same shape, arrange | positioning it on the lower side, and overlapping this foaming resin block body 20 for embankment on it. In order to prevent displacement when used as a foam resin block (filling block) 20A, as shown in FIG. 2, a fitting connecting portion 25 is provided at the tip of the central column portion 22a in the central portion, and the fitting protrusion It is comprised by the part 25a and the fitting recessed part 25b.

この嵌合連結部２５は、例えば図２に示すように、中央部の９個の中央支柱部２２ａのうち対角位置の４つの一方の２つに嵌合凸部２５ａを形成し、他の方の２つに嵌合凹部２５ｂを形成することで、同一形状の盛土用発泡樹脂ブロック体２０を反転して下側に配置して重ねることで、嵌合凹凸部２５ａ、２５ｂを互いに嵌合連結して一つの盛土用発泡樹脂ブロック（盛土用ブロック）２０Ａとすることができる。   For example, as shown in FIG. 2, the fitting connecting portion 25 is formed with fitting convex portions 25 a on two of the four diagonal positions among the nine central supporting column portions 22 a in the central portion. By forming the fitting recesses 25b on the two sides, the embossed foam resin blocks 20 having the same shape are inverted and placed on the lower side and overlapped, thereby fitting the fitting irregularities 25a and 25b together. It can connect and it can be set as one foaming resin block for embankment (block for embankment) 20A.

そして、これらの嵌合連結部２５の形状としては、例えば円柱状の嵌合凸部２５ａと円筒状の嵌合凹部２５ｂとしたり、さらに、円柱状の側面あるいは、円筒状の側面に中心軸方向と平行に縦の突条を１〜複数本形成して強固に連結できるようにしたり、円周方向に沿う横の突条を１〜複数本形成して強固に連結できるようにしても良い。   And as the shape of these fitting connection parts 25, it is set as column-shaped fitting convex part 25a and cylindrical fitting concave part 25b, for example, Furthermore, it is a central axis direction to a column-shaped side or cylindrical side. One or more vertical ridges may be formed in parallel with each other so that they can be firmly connected, or one to a plurality of horizontal ridges along the circumferential direction may be formed and firmly connected.

このような嵌合連結部２５の大きさは、互いに連結してずれを防止できば良く、例えば上記寸法の盛土用発泡樹脂ブロック体（１ｍ×１ｍ×２５０ｍｍ）の場合、嵌合凹凸部２５ａ、２５ｂの大きさを直径８０ｍｍ、高さあるいは深さを１０ｍｍとしてある。また、突条を形成する場合には、幅を１〜３ｍｍ、高さを０．５〜１ｍｍとすれば良く、高すぎると、連結する時に入れづらくなる。   The size of the fitting connecting portion 25 is not limited as long as it can be connected to each other to prevent deviation. For example, in the case of a foamed resin block body for embankment of the above dimensions (1 m × 1 m × 250 mm), the fitting uneven portion 25a, The size of 25b is 80 mm in diameter and the height or depth is 10 mm. Moreover, when forming a protrusion, what is necessary is just to make a width | variety 1-3mm and height 0.5-1mm, and when too high, it will become difficult to insert when connecting.

なお、嵌合連結部２５の配置および個数は、上記の場合に限らず、盛土用発泡樹脂ブロック体を反転して互いを嵌合連結できる配置や個数であれば良い。   In addition, arrangement | positioning and the number of the fitting connection parts 25 are not restricted to said case, What is necessary is just the arrangement | positioning and number which can invert the foaming resin block body for embankment and mutually connect.

さらに、２つの盛土用発泡樹脂ブロック体２０を反転して連結した盛土用発泡樹脂ブロック２０Ａには、その４側面を囲むように不織布が取り付けられ、水の流入排出は行われるが、土砂などの浸入を防止できるようにしても良く、特に土砂と接する位置に敷設される盛土用発泡樹脂ブロック２０Ａに取り付けることが有効となる。   Further, the embedding foam resin block 20A, which is formed by inverting two embedding foam resin blocks 20, is attached with a non-woven fabric so as to surround its four side surfaces, and water is introduced and discharged. It may be possible to prevent intrusion, and it is particularly effective to attach to the embankment foam resin block 20A laid at a position in contact with the earth and sand.

このように構成した盛土用発泡樹脂ブロック体２０を用いて、盛土を施工する場合には、２つの盛土用発泡樹脂ブロック体２０を反転し、必要に応じて接着剤などを用いて各支柱部２２および嵌合連結部２５を連結した盛土用発泡樹脂ブロック２０Ａを用意するとともに、必要に応じて盛土用発泡樹脂ブロック２０Ａの４側面を囲むように不織布を取り付けたものを用意しておく。   When embankment is constructed using the embedding foam resin block body 20 configured as described above, the two embedding foam resin block bodies 20 are reversed, and each support portion is used with an adhesive or the like as necessary. The embedding foam resin block 20A to which 22 and the fitting connection part 25 are connected is prepared, and a non-woven fabric attached so as to surround the four side surfaces of the embedding foam resin block 20A is prepared.

そして、盛土を構築する地盤を掘削する等で基礎工事を行った後、２つの盛土用発泡樹脂ブロック体２０を連結した盛土用発泡樹脂ブロック２０Ａを前後左右に並べるように敷設する。なお、敷設構築には、通常のＥＰＳ軽量盛土工法に使用される爪付きの連結金具などを使用すれば良い。     And after performing foundation work, such as excavating the ground which constructs embankment, it lays out so that the foaming resin block 20A for embankment which connected two foaming resin block bodies 20 for embankment may be arranged in order front and rear and right and left. In addition, what is necessary is just to use the coupling metal fitting with a nail | claw etc. which are used for the usual EPS light weight embankment method for laying construction.

これら盛土用発泡樹脂ブロック２０Ａを、地下水の水位の上昇や、季節的な降雨や洪水などで冠水が予想される高さまで積み重ねるようにし、例えば図３に示すように、盛土用発泡樹脂ブロック２０Ａを１段（盛土用発泡樹脂ブロック体２０の２段分）だけ敷設したのち、その上には、通常の中実の発泡樹脂ブロックBを盛土の形状に合わせて必要段数積み重ねるように構築する。   These foaming resin blocks 20A for embankment are stacked up to the height at which flooding is expected due to the rise of groundwater level, seasonal rainfall or flooding. For example, as shown in FIG. After laying only one level (two levels of the foamed resin block body 20 for embankment), a normal solid foamed resin block B is constructed thereon so as to be stacked in the required number of steps according to the shape of the embankment.

この構築の際には、盛土用発泡樹脂ブロック体２０の平面形状が左右対称としてあるので、左右前後に敷設する場合に方向性に注意する必要がなく、簡単に敷設作業を行うことができる。   In this construction, since the planar shape of the foamed resin block body 20 for embankment is left-right symmetric, it is not necessary to pay attention to the directionality when laying back and forth, and can be easily laid.

このような盛土用発泡樹脂ブロック体２０によれば、発泡樹脂板２１に一定の配列で突出させて設けた複数の支柱部２２同士を突き合わせて盛土用発泡樹脂ブロック２０Ａとしたので、円錐台形の支柱部２２によって荷重を均一に支持することができるとともに、小さい横断面積で大きな圧縮強度を確保することができる。   According to such a foamed resin block body 20 for embankment, since the plurality of support portions 22 provided by projecting in a fixed arrangement on the foamed resin plate 21 are brought into contact with each other to form the foamed resin block 20A for embankment, A load can be uniformly supported by the support column 22, and a large compressive strength can be secured with a small cross-sectional area.

これにより、圧縮強度を高めると同時に、空隙率を高めることができ、６０〜６５％の空隙率にすることが可能となる。   Thereby, at the same time as increasing the compressive strength, the porosity can be increased, and the porosity can be set to 60 to 65%.

また、浮力に対して発泡樹脂板２１の一方側では、支柱部２２の側方を水の注排水路とし、他方側では、発泡樹脂板２１に一定配列で複数設けた貫通部２３およびこれら貫通部２３と連通させて形成した溝部２４を水の注排水路とすることができ、急激な水位上昇や冠水に対しても円滑に水を注排水することができ、浮力を極力抑えることができるとともに、水位が低下した場合の水の排出も円滑に行われ、軽量性の回復も早期に行うことができる。   In addition, on one side of the foamed resin plate 21 with respect to buoyancy, the side of the support column 22 is a water pouring / drainage channel, and on the other side, a plurality of through portions 23 provided in a fixed arrangement on the foamed resin plate 21 and these penetrating holes are provided. The groove portion 24 formed in communication with the portion 23 can be used as a water pouring / drainage channel, and water can be smoothly poured / drained against a sudden rise in water level or submersion, and buoyancy can be suppressed as much as possible. At the same time, the water is smoothly discharged when the water level is lowered, and the light weight can be recovered at an early stage.

また、この盛土用発泡樹脂ブロック体２０によれば、支柱部２２に設けた互いに嵌合連結可能な嵌合凸部２５ａと嵌合凹部２５ｂとを反転組み合わせ可能に配置してあるので、１つの形状の盛土用発泡樹脂ブロック体２０を２つ組み合わせて盛土用発泡樹脂ブロック２０Ａにでき、しかもずれを防止して安定性を向上することができるとともに、一層強固な盛土用発泡樹脂ブロック２０Ａにすることができる。   Moreover, according to this foamed resin block body 20 for embankment, since the fitting convex part 25a provided in the support | pillar part 22 and the fitting convex part 25a and the fitting concave part 25b which are mutually connectable are arrange | positioned so that reversal combination is possible, one Two embedding foam resin blocks 20 having a shape can be combined to form a foam resin block 20A for embankment, and can be prevented from slipping to improve stability, and can be made stronger foam resin block 20A for embankment. be able to.

さらに、支柱部２２が発泡樹脂板２１と一体の円錐台形としてあるので、形状がシンプルであり、成形が容易にできるとともに、成形に必要な金型も製作が容易で安価に製作することができる。   Furthermore, since the support column 22 has a truncated cone shape integrated with the foamed resin plate 21, the shape is simple, the molding can be easily performed, and the mold necessary for the molding can be easily manufactured at a low cost. .

次に、この発明の盛土用発泡樹脂ブロック体の他の一実施の形態について、図４に基づき詳細に説明するが、すでに説明した上記実施の形態と同一部分には、同一記号を記し、重複する説明は省略する。   Next, another embodiment of the foamed resin block body for embankment according to the present invention will be described in detail with reference to FIG. 4. The description to be omitted is omitted.

図４は、この発明の盛土用発泡樹脂ブロック体の一実施の形態にかかり、（ａ）は背面および左右側面と同一の正面図、（ｂ）は平面図、（ｃ）は底面図である。   FIG. 4 is related to one embodiment of the foamed resin block body for embankment of the present invention, (a) is the same front view as the back and left and right sides, (b) is a plan view, and (c) is a bottom view. .

この盛土用発泡樹脂ブロック体は、軟弱地盤などで盛土を行う場合に、土や土砂などに代えて使用される発泡ポリスチレンなどの合成樹脂発泡体からなる盛土用ブロック体であって、同一形状のブロック体を反転して下側に配置して重ねることで一つの盛土用ブロックとして使用するもので、例えば縦横の大きさが１ｍとされる。   This foamed resin block body for embankment is a block body for embankment made of synthetic resin foam such as expanded polystyrene used in place of soil or earth and sand when embankment is performed on soft ground, etc. The block body is inverted and arranged on the lower side and overlapped to be used as one embankment block. For example, the vertical and horizontal sizes are 1 m.

この盛土用発泡樹脂ブロック体３０では、すでに説明した盛土用発泡樹脂ブロック体２０の発泡樹脂板２１に形成した貫通孔２３に連通する溝部２４を取り除いたものであり、発泡樹脂板２１の支柱部２２と反対側の表面は平坦面とされ、貫通部２３として貫通孔２３が開口している。   In the foamed resin block body 30 for embankment, the groove portion 24 that communicates with the through hole 23 formed in the foamed resin plate 21 of the foamed resin block body 20 for embankment already described is removed. The surface opposite to the surface 22 is a flat surface, and a through hole 23 is opened as a through portion 23.

これにより、盛土用発泡樹脂ブロック体３０の形状を簡素化し、成形性を高めるとともに、コスト低減を図るようにしている。   Thereby, the shape of the foamed resin block body 30 for embankment is simplified, the moldability is improved, and the cost is reduced.

なお、この盛土用発泡樹脂ブロック体３０のこれ以外の他の構成は、盛土用発泡樹脂ブロック体２０と同一である。   The other structure of the foamed resin block body 30 for embankment is the same as that of the foamed resin block body 20 for embankment.

このように構成した盛土用発泡樹脂ブロック体３０を用いて、盛土を施工する場合には、２つの盛土用発泡樹脂ブロック体３０を反転して連結した盛土用発泡樹脂ブロック３０Ａ（３０Ａについては、図３および図４に記載はないが、図３における２０Ａと読み替えたものに相当する、以下同じ）を用意するとともに、必要に応じて盛土用発泡樹脂ブロック３０Ａの４側面を囲むように不織布を取り付けたものを用意しておく。   When embankment is constructed using the embedding foam resin block body 30 configured as described above, the embedding foam resin block 30A (for 30A, in which the two embedding foam resin block bodies 30 are connected by being inverted. Although not described in FIGS. 3 and 4, a non-woven fabric is provided so as to surround the four side surfaces of the foamed resin block 30 </ b> A for embankment, as necessary. Prepare what you have installed.

そして、盛土を構築する地盤を掘削する等で基礎工事を行った後、２つの盛土用発泡樹脂ブロック体３０を連結した盛土用発泡樹脂ブロック３０Ａを前後左右に並べるように敷設する。   And after performing foundation work, such as excavating the ground which constructs embankment, it lays out so that the foaming resin block 30A for embankment which connected two foaming resin block bodies 30 for embankment may be arranged in order front and rear and right and left.

これら盛土用発泡樹脂ブロック３０Ａを、地下水の水位の上昇や、季節的な降雨や洪水などで冠水が予想される高さまで積み重ねるようにし、例えば図３のように、盛土用発泡樹脂ブロック３０Ａを１段（盛土用発泡樹脂ブロック体３０の２段分）だけ敷設したのち、その上には、通常の中実の発泡樹脂ブロックBを盛土の形状に合わせて必要段数積み重ねるようにし、通常のＥＰＳ軽量盛土工法に使用される爪付きの連結金具などを使用して盛土を構築する。     These embedding foam resin blocks 30A are piled up to a height at which submergence is expected due to a rise in the level of groundwater or seasonal rainfall or flooding. For example, as shown in FIG. After laying only the steps (two steps of the foamed resin block body 30 for embankment), the usual solid foamed resin block B is stacked on top of it according to the shape of the embankment, and the normal EPS lightweight The embankment is constructed using the connecting fittings with claws used in the embankment method.

この構築の際には、盛土用発泡樹脂ブロック体３０も平面形状が左右対称としてあるので、左右前後に敷設する場合に方向性に注意する必要がなく、簡単に敷設作業を行うことができる。   At the time of this construction, the embedding foam resin block body 30 also has a left-right symmetrical plane shape, so that it is not necessary to pay attention to the direction when laying back and forth, and can be laid easily.

また、この盛土用発泡樹脂ブロック体３０によっても、発泡樹脂板２１に一定の配列で突出させて設けた複数の支柱部２２同士を突き合わせて盛土用発泡樹脂ブロック３０Ａとするので、円錐台形の支柱部２２によって荷重を均一に支持することができるとともに、小さい横断面積で大きな圧縮強度を確保することができる。   In addition, the embedding foam resin block body 30 also makes a foamed resin block 30A for embankment by abutting a plurality of strut portions 22 provided to protrude from the foam resin plate 21 in a fixed arrangement. The load can be uniformly supported by the portion 22 and a large compressive strength can be ensured with a small cross-sectional area.

これにより、圧縮強度を高めると同時に、空隙率を高めることができ、６０〜６５％の空隙率にすることが可能となり、万一、冠水する場合にも浮力を抑えることができる。   As a result, it is possible to increase the compressive strength and at the same time increase the porosity, so that a porosity of 60 to 65% can be achieved, and buoyancy can be suppressed even in the case of flooding.

また、浮力に対して発泡樹脂板２１に突設した支柱部２２の側方を水の注排水路とするとともに、発泡樹脂板２１に一定配列で複数設けた貫通部２３としての貫通孔２３aを水の注排水路とすることができ、急激な水位上昇や冠水に対しても円滑に水を注排水することができ、浮力を極力抑えることができるとともに、水位が低下した場合の水の排出も円滑に行われ、軽量性の回復も早期に行うことができる。   Further, the side of the column portion 22 protruding from the foamed resin plate 21 with respect to the buoyancy is used as a water pouring / drainage channel, and through holes 23a as a plurality of through portions 23 provided in a fixed arrangement on the foamed resin plate 21 are provided. Water can be poured and drained, water can be smoothly poured and drained against sudden water level rise and flooding, buoyancy can be suppressed as much as possible, and water discharge when the water level drops Can be carried out smoothly, and light weight can be recovered early.

したがって、予想される地下水などの水位を、２つ組み合わせる上側の盛土用発泡樹脂ブロック体３０の発泡樹脂板２１の下方にしておけば、発泡樹脂板２１の表面に溝がなくても横方向への排水性を大きく損ねることがなく、形状を単純化して成形を容易にでき、コスト低減を図ることもできる。   Therefore, if the water level such as the expected groundwater is set below the foamed resin plate 21 of the upper embankment foamed resin block body 30 to combine two, the surface of the foamed resin plate 21 can be laterally moved even if there is no groove. Therefore, the shape can be simplified and the molding can be facilitated, and the cost can be reduced.

さらに、この盛土用発泡樹脂ブロック体３０でも、支柱部２２に設けた互いに嵌合連結可能な嵌合凸部２５ａと嵌合凹部２５ｂとを反転組み合わせ可能に配置してあるので、１つの形状の盛土用発泡樹脂ブロック体３０を２つ組み合わせて盛土用発泡樹脂ブロック３０Ａにでき、しかもずれを防止して安定性を向上することができるとともに、一層強固な盛土用発泡樹脂ブロック３０Ａにすることができる。   Further, even in the foamed resin block body 30 for embankment, the fitting convex portion 25a and the fitting concave portion 25b provided in the support column portion 22 that can be fitted and connected to each other are arranged so as to be able to be reversed and combined. Two embedding foam resin blocks 30A can be combined into a foam resin block 30A for embankment, and the stability can be improved by preventing slippage, and the foam resin block 30A for embankment can be made stronger. it can.

また、支柱部２２が発泡樹脂板２１と一体の円錐台形としてあるので、形状がシンプルであり、成形が容易にできるとともに、成形に必要な金型も製作が容易で安価に製作することができる。   Further, since the column portion 22 is formed as a truncated cone shape integrated with the foamed resin plate 21, the shape is simple, the molding can be easily performed, and the mold necessary for the molding can be easily manufactured at a low cost. .

次に、この発明の盛土用発泡樹脂ブロック体の他の一実施の形態について、図５に基づき詳細に説明するが、すでに説明した上記２つの実施の形態と同一部分には、同一記号を記し、重複する説明は省略する。   Next, another embodiment of the foamed resin block body for embankment according to the present invention will be described in detail with reference to FIG. 5. However, the same parts as those in the above-described two embodiments are denoted by the same symbols. The overlapping description is omitted.

図５は、この発明の盛土用発泡樹脂ブロック体の一実施の形態にかかり、（ａ）は背面および左右側面と同一の正面図、（ｂ）は平面図、（ｃ）は底面図である。   FIG. 5 is related to one embodiment of the foamed resin block body for embankment of the present invention, (a) is the same front view as the back and left and right sides, (b) is a plan view, and (c) is a bottom view. .

この盛土用発泡樹脂ブロック体は、軟弱地盤などで盛土を行う場合に、土や土砂などに代えて使用される発泡ポリスチレンなどの合成樹脂発泡体からなる盛土用ブロック体であって、同一形状のブロック体を反転して下側に配置して重ねることで一つの盛土用ブロックとして使用するもので、例えば縦横の大きさが１ｍとされる。   This foamed resin block body for embankment is a block body for embankment made of synthetic resin foam such as expanded polystyrene used in place of soil or earth and sand when embankment is performed on soft ground, etc. The block body is inverted and arranged on the lower side and overlapped to be used as one embankment block. For example, the vertical and horizontal sizes are 1 m.

この盛土用発泡樹脂ブロック体４０では、発泡樹脂板４１の厚さを厚くしてあり、例えばすでに説明した盛土用発泡樹脂ブロック体２０、３０の発泡樹脂板２１に比べて２倍程度としてある。   In the foamed resin block body 40 for embankment, the thickness of the foamed resin plate 41 is increased. For example, the foamed resin block body 41 is about twice as large as the foamed resin board 21 of the embankment foamed resin block bodies 20 and 30 described above.

これにより、この盛土用発泡樹脂ブロック体４０の強度を高めるようにしている。   Thereby, the strength of the foamed resin block body 40 for embankment is increased.

また、この盛土用発泡樹脂ブロック体４０では、支柱部の形状を円錐台形の支柱部２２と角錐台形の支柱部４２とを混在させ、それぞれの方向や中央部、側面部、隅部で一定の配列となるように配置してある。   Further, in this foamed resin block body 40 for embankment, the shape of the columnar part is a mixture of the truncated cone-shaped columnar part 22 and the truncated pyramid-shaped columnar part 42, and the direction, the central part, the side part, and the corner part are constant. They are arranged in an array.

すなわち、隅部に４分の1の円錐台形の隅部支柱部２２ｃをそれぞれ形成するとともに、各側面に隅部支柱部２２cから円錐台形と角錐台形とが交互になるように、側面中央部に１つの半円錐台形の側面支柱部２２bが、その両側に２つの半角錐台形の側面支柱部４２bが形成され、中央部には、９個のうち対角位置の４つが角錐台形の中央支柱部４２aとして形成され、中心を含む５個が円錐台形の中央支柱部２２aとして形成してある。   That is, a quarter truncated cone support 22c is formed at each corner, and at the center of the side so that the truncated cone and the truncated pyramid alternate from each corner support 22c on each side. One half-conical trapezoidal side support column 22b is formed with two half-pyramidal side support columns 42b on both sides thereof, and four of the nine diagonal positions are pyramid-shaped central support columns in the center. It is formed as 42a, and five pieces including the center are formed as a central post portion 22a having a truncated cone shape.

また、この盛土用発泡樹脂ブロック体４０では、同一形状の盛土用発泡樹脂ブロック体４０を反転して下側に配置して重ねることで一つの盛土用発泡樹脂ブロック（盛土用ブロック）４０Ａ（４０Ａについては、図３および図５に記載はないが、図３における２０Ａと読み替えたものに相当する、以下同じ）として使用する場合のずれを防止するため、図５に示すように、中央部の中央支柱部４２ａの先端に嵌合連結部４５が設けられ、嵌合凸部４５ａと嵌合凹部４５ｂとで構成される。   Moreover, in this foaming resin block body 40 for embankment, the foaming resin block body 40 for embankment of the same shape is reversed, arrange | positioned on the lower side, and is piled up, and one foaming resin block for embankment (block for embankment) 40A (40A 3 and FIG. 5, although not described in FIG. 3 and FIG. 5, it corresponds to 20A in FIG. A fitting connection portion 45 is provided at the tip of the central support post portion 42a, and includes a fitting convex portion 45a and a fitting concave portion 45b.

この嵌合連結部４５は、例えば図５に示すように、中央部の４個の中央支柱部４２ａのうち一方の対角位置の２つに四角柱状の嵌合凸部４５ａを形成し、他の方の２つに四角筒状の嵌合凹部４５ｂを形成することで、同一形状の盛土用発泡樹脂ブロック体４０を反転して下側に配置して重ねることで、嵌合凹凸部４５ａ、４５ｂを互いに嵌合連結して一つの盛土用発泡樹脂ブロック（盛土用ブロック）４０Ａとすることができるようにしてある。   For example, as shown in FIG. 5, the fitting connection portion 45 is formed with a square columnar fitting convex portion 45 a at two diagonal positions among the four central support column portions 42 a in the central portion, and the like. By forming the square cylindrical fitting recess 45b in the two of the two, the embedding concave and convex portion 45a, 45b can be fitted and connected to each other to form one embedding foam resin block (filling block) 40A.

Alternatively, one or more horizontal protrusions may be formed along the periphery so that they can be firmly connected.

なお、他の貫通部２３および溝部２４などの構成はすでに説明した盛土用発泡樹脂ブロック体２０と同一であるので説明は省略する。   In addition, since the structure of the other penetration part 23, the groove part 24, etc. is the same as the foamed resin block body 20 for embankment already demonstrated, description is abbreviate | omitted.

このように構成した盛土用発泡樹脂ブロック体４０を用いて行う盛土の構築の工程は、すでに説明した盛土用発泡樹脂ブロック体２０の場合と同様であるので、説明を省略する。   Since the embankment construction process performed using the embedding foam resin block body 40 configured in this manner is the same as that of the embankment foam resin block body 20 already described, the description thereof is omitted.

この盛土用発泡樹脂ブロック体４０によれば、発泡樹脂板４１が厚くしてあるので、剛性や圧縮強度を一層高くすることができる。   According to the foamed resin block body 40 for embankment, since the foamed resin plate 41 is thickened, rigidity and compressive strength can be further increased.

さらに、この盛土用発泡樹脂ブロック体４０によっても、すでに説明した盛土用発泡樹脂ブロック体２０の場合と同様の作用効果を奏するが、その説明を省略する。   Further, the foamed resin block body 40 for embankment also has the same effect as that of the foamed resin block body 20 for embankment described above, but the description thereof is omitted.

次に、この発明の盛土用発泡樹脂ブロック体の他の一実施の形態について、図６に基づき詳細に説明するが、すでに説明した上記各実施の形態と同一部分には、同一記号を記し、重複する説明は省略する。   Next, another embodiment of the foamed resin block body for embankment of the present invention will be described in detail with reference to FIG. 6, but the same parts as those of the above-described embodiments are denoted by the same symbols, A duplicate description is omitted.

図６は、この発明の盛土用発泡樹脂ブロック体の一実施の形態にかかり、（ａ）は背面および左右側面と同一の正面図、（ｂ）は平面図、（ｃ）は底面図である。   FIG. 6 is related to one embodiment of the foamed resin block body for embankment of the present invention, (a) is the same front view as the back and left and right sides, (b) is a plan view, and (c) is a bottom view. .

この盛土用発泡樹脂ブロック体は、軟弱地盤などで盛土を行う場合に、土や土砂などに代えて使用される発泡ポリスチレンなどの合成樹脂発泡体からなる盛土用ブロック体であって、同一形状のブロック体を反転して下側に配置して重ねることで一つの盛土用ブロックとして使用するもので、例えば縦横の大きさが１ｍとされる。   This foamed resin block body for embankment is a block body for embankment made of synthetic resin foam such as expanded polystyrene used in place of soil or earth and sand when embankment is performed on soft ground, etc. The block body is inverted and arranged on the lower side and overlapped to be used as one embankment block. For example, the vertical and horizontal sizes are 1 m.

この盛土用発泡樹脂ブロック体５０では、発泡樹脂板５１の厚さを厚くしてあり、例えばすでに説明した盛土用発泡樹脂ブロック体２０、３０の発泡樹脂板２１に比べて２倍程度としてあり、盛土用発泡樹脂ブロック体４０と同一の厚さとしてある。   In the foamed resin block body 50 for embankment, the thickness of the foamed resin plate 51 is increased. For example, the foamed resin block body 50 is about twice as large as the foamed resin plate 21 of the embankment foamed resin block bodies 20 and 30 described above. The thickness is the same as the foamed resin block body 40 for embankment.

これにより、盛土用発泡樹脂ブロック体５０の剛性や圧縮強度を一層高くするようにしている。   Thereby, the rigidity and compressive strength of the foamed resin block body 50 for embankment are made higher.

また、この盛土用発泡樹脂ブロック体５０では、支柱部の形状を円錐台形の支柱部２２と角錐台形の支柱部４２とを混在させるとともに、個数を減少し、それぞれの方向や、中央部、側面部、隅部で一定の配列となるように配置してある。   Further, in the foamed resin block body 50 for embankment, the shape of the support column is a mixture of the truncated cone-shaped support column 22 and the truncated pyramid-shaped support column 42, and the number is reduced, and each direction, center portion, side surface is reduced. It arrange | positions so that it may become a fixed array in a part and a corner.

すなわち、隅部に４分の1の円錐台形の隅部支柱部２２ｃをそれぞれ形成するとともに、各側面の側面中央部に１つの半角錐台形の側面支柱部４２ｂが形成され、中央部には、５個の角錐台形の中央支柱部４２ａが十字状に配置されて形成してある。   That is, a quarter-conical corner column support 22c is formed at each corner, and one half-pyramidal side support 42b is formed at the center of each side surface. Five pyramidal trapezoidal central support portions 42a are arranged in a cross shape.

したがって、すでに説明した盛土用発泡樹脂ブロック体２０，３０，４０に比べて支柱部２２，４２の個数が少なくなっており、その分だけ空隙率が大きくなり、冠水時などの浮力の低減を図ることができるようになっている。   Therefore, the number of support portions 22, 42 is smaller than the foamed resin block bodies 20, 30, 40 for embankment already described, and the porosity is increased by that amount, thereby reducing buoyancy during submergence. Be able to.

また、発泡樹脂板５１を貫通して設けられる貫通部５３は貫通部２３としての貫通孔２３ａに比べて大きな円筒状の貫通孔５３ａで構成されて等間隔に正方形の頂点に４個形成してある。   Further, the through-holes 53 provided through the foamed resin plate 51 are composed of cylindrical through-holes 53a which are larger than the through-holes 23a as the through-holes 23, and four are formed at square vertices at equal intervals. is there.

The bottom surface of the groove 54a is located on and communicates with the through hole 53a.

さらに、この盛土用発泡樹脂ブロック体５０の嵌合連結部５５は、図６に示すように、中央部の周囲に位置する４個の中央支柱部４２ａのうち一方の対角位置の２つに円柱状の嵌合凸部５５ａを形成し、他の方の２つに円筒状の嵌合凹部５５ｂを形成してあり、同一形状の盛土用発泡樹脂ブロック体５０を反転して下側に配置して重ねることで、嵌合凹凸部５５ａ、５５ｂを互いに嵌合連結して一つの盛土用発泡樹脂ブロック（盛土用ブロック）５０Ａとすることができるようにしてある。   Furthermore, as shown in FIG. 6, the fitting connection portion 55 of the foamed resin block body 50 for embankment is provided at two diagonal positions on one of the four central strut portions 42a located around the central portion. The cylindrical fitting convex part 55a is formed, and the cylindrical fitting concave part 55b is formed on the other two, and the foamed resin block body 50 for embankment having the same shape is inverted and arranged on the lower side. Thus, the fitting uneven portions 55a and 55b are fitted and connected to each other to form one embedding foam resin block (banking block) 50A.

なお、これらの嵌合連結部５５の場合も同様に、嵌合凹凸部５５a,５５ｂの側面に中心軸方向と平行に縦の突条を１〜複数本形成して強固に連結できるようにしたり、周囲に沿って横の突条を１〜複数本形成して強固に連結できるようにしても良い。   Similarly, in the case of these fitting connection portions 55, one or more vertical protrusions are formed on the side surfaces of the fitting uneven portions 55a and 55b in parallel to the central axis direction so that they can be firmly connected. One or a plurality of horizontal protrusions may be formed along the periphery so that they can be firmly connected.

このように構成した盛土用発泡樹脂ブロック体５０を用いて行う盛土の構築の工程は、すでに説明した盛土用発泡樹脂ブロック体２０の場合と同様であるので、説明を省略する。   Since the embankment construction process performed using the embedding foam resin block body 50 configured as described above is the same as that of the embankment foam resin block body 20 described above, description thereof is omitted.

この盛土用発泡樹脂ブロック体５０によれば、発泡樹脂板５１が厚くしてあるので、剛性や圧縮強度を一層高くすることができるとともに、支柱部２２，４２の個数が少ない分だけ空隙率が大きく、冠水時の浮力を一層抑制することができる。   According to the foamed resin block body 50 for embankment, since the foamed resin plate 51 is thickened, the rigidity and the compressive strength can be further increased, and the porosity is reduced by the smaller number of the column portions 22 and 42. Large and can further suppress buoyancy during flooding.

なお、この盛土用発泡樹脂ブロック体５０によっても、すでに説明した盛土用発泡樹脂ブロック体２０の場合と同様の作用効果を奏するが、その説明は省略する。   The embedding foam resin block body 50 also has the same effects as the embankment foam resin block body 20 described above, but the description thereof is omitted.
