Description

この発明は、住宅地、公園、駐車場や工場敷地等において雨水等を貯留並びに浸透させる地下貯水施設であって、施設を施工する際に内部に積層した充填部材が埋め戻しの際の偏土圧によって傾いたり、倒れたりすることのない雨水等の貯留施設並びに浸透施設に関する。   The present invention is an underground water storage facility for storing and infiltrating rainwater and the like in residential areas, parks, parking lots, factory sites, etc., and when the facility is constructed, the filling members stacked inside are uneven soil when backfilling The present invention relates to storage facilities such as rainwater and infiltration facilities that do not tilt or fall down due to pressure.

近年、都市部では集中豪雨による家屋の浸水や河川の氾濫を防止するために、雨水等の貯留浸透施設が施工されている。地表面のほとんどが建物や舗装などの不浸透面で覆われている都市部では、雨水等は地下に浸透せず低地に流入して家屋を浸水させたり、河川を氾濫させる危険が高まっている。また、水の使用量が年々増大しており、水源地での降雨量が少ないと水不足となる危険がある。そのために水対策として、雨水を一定時間貯留した後、河川等に順次放流したり、積極的に地下に浸透させることにより、雨水等による河川の氾濫、家屋の浸水災害を防止したり、さらに、一時貯留した雨水を汲み上げて利用するための雨水等の貯留施設並びに浸透施設が施工されている。   In recent years, storage and infiltration facilities such as rainwater have been constructed in urban areas to prevent flooding of houses and rivers due to heavy rain. In urban areas where most of the ground surface is covered with impervious surfaces such as buildings and pavements, there is an increased risk that rainwater will not penetrate underground and flow into the lowlands, flooding houses and flooding rivers. . Also, the amount of water used is increasing year by year, and there is a risk of water shortage if the rainfall at the water source is small. Therefore, as a countermeasure against water, rainwater is stored for a certain period of time and then released sequentially into rivers, etc., and actively infiltrated underground, preventing flooding of rivers due to rainwater, etc. Rainwater storage facilities and infiltration facilities are being constructed to pump and use temporarily stored rainwater.

このような雨水等の浸透施設として、例えば、特開２０００−１６０６０６号公報記載の「雨水貯留装置」、特開２００５−００２６２０号公報の「地下貯留及び／又は浸透槽」に記載されている。これらの施設は、例えば図１０に示すように、地面を掘り下げてタンク部１を構成し、上記タンク部１内に充填部材３を充填して形成される。   Such infiltration facilities such as rainwater are described in, for example, “Rainwater storage device” described in JP-A-2000-160606 and “Underground storage and / or infiltration tank” in JP-A-2005-002620. For example, as shown in FIG. 10, these facilities are formed by digging the ground to form the tank portion 1 and filling the tank portion 1 with a filling member 3.

即ち、砕石や砂利等を敷設して平坦にした底部２からグランドライン付近まで、複数の充填部材３を縦横且つ上下に配設して充填する。これらの充填部材３の周りの空間部分を埋め戻し土４で埋め戻した後、充填部材の最上部には被覆手段５が施される。被覆手段５は、充填部材３の上に蓋体５ａを載置し、蓋体５ａの上面に透水性シート５ｂ、礫層５ｃ、上層５ｄを順次積層することによって構成されている。   That is, a plurality of filling members 3 are arranged vertically and horizontally and filled from the bottom portion 2 laid flat by crushed stone, gravel or the like to the vicinity of the ground line. After the space around these filling members 3 is backfilled with the backfill soil 4, the covering means 5 is applied to the top of the filling member. The covering means 5 is configured by placing a lid 5a on the filling member 3 and sequentially laminating a water permeable sheet 5b, a gravel layer 5c, and an upper layer 5d on the upper surface of the lid 5a.

なお、図７においては、通常施工されるような雨水を導入する側溝、溢れた水を排出する排出管、あるいは水を汲み上げる揚水管等は省略されている。
特開２０００−１６０６０６号公報 特開２００５−００２６２０号公報 In FIG. 7, a side groove for introducing rainwater, a discharge pipe for discharging overflowing water, a pumping pipe for pumping water, and the like, which are normally constructed, are omitted.
JP 2000-160606 A JP-A-2005-002620

しかしながら、施設を施工する際に次のような問題がある。タンク部を形成するために地面を掘り下げる際に、側面を垂直に掘り下げることはできないから、傾斜面に掘り下げることになる。また、充填する充填部材の寸法通りに掘り下げることはできないから、タンク部の側面と充填した充填部材との間には空隙が形成されることになる。この空隙は埋め戻されることになるが、埋め戻しの際に次のような問題が生じる。   However, there are the following problems when constructing facilities. When digging the ground to form the tank portion, the side surface cannot be dug vertically, so it is dug to an inclined surface. Moreover, since it cannot dig up according to the dimension of the filling member to fill, a space | gap will be formed between the side surface of a tank part and the filled filling member. This void is backfilled, but the following problems occur during backfilling.

充填された充填部材の周囲を埋め戻す際には、四周の高さが均等になるように少しずつ埋め戻して行くことが望ましいが、種々の条件によって埋め戻し用の作業用機械が周囲に回り込めない場合がある。例えば、図１０に示すように、道路７とは反対側に建築物８等がある場合に、建築物８等側から掘り下げることによりタンク部を形成することはできるが、充填部材を充填した後埋め戻す際には作業用機械が建築物８等側に回り込むことはできない。このような場合には、まず道路７側の空隙を埋め戻した後、作業用機械を充填部材の上に載せて建築物８等側の空隙を埋め戻すことになる。   When refilling the periphery of the filled filling member, it is desirable to gradually backfill so that the height of the four circumferences is equal, but depending on various conditions, the work machine for backfilling rotates around. It may not be possible. For example, as shown in FIG. 10, when there is a building 8 or the like on the opposite side of the road 7, the tank portion can be formed by digging from the building 8 etc. side, but after filling the filling member When refilling, the work machine cannot go around to the building 8 or the like side. In such a case, after first filling the gap on the road 7 side, the working machine is placed on the filling member to fill the gap on the building 8 side or the like.

上記のように周囲を均等に埋め戻すことができない場合に、充填部材３は、タンク部１内に縦横に並べ縦方向に積層することによって充填されているが、材質はプラスチックであり軽量であるから、積層された充填部材３は先に埋め戻す側からの土圧によって充填部材の積層体全体が傾いたり、崩れる虞がある。特に、貯水効率を上げるために枠部に支柱部を突設して形成した充填部材においては、支柱部を載置することによって積層されているに過ぎないから、偏土圧の影響を受け易い。   When the surroundings cannot be back-filled evenly as described above, the filling member 3 is filled by arranging vertically and horizontally in the tank portion 1 and is stacked vertically, but the material is plastic and lightweight. Therefore, the laminated member 3 laminated may be inclined or collapsed due to the earth pressure from the backfill side. In particular, in the filling member formed by projecting the support column to the frame portion in order to increase the water storage efficiency, it is only laminated by placing the support column, and thus is easily affected by the uneven earth pressure. .

そして、タンク部が深いほど偏土圧の影響を受け易いが、偏土圧によって傾いたり、崩れた場合には、これらの充填部材を取り除き再度積層しなければならない。タンク部が深ければそれだけ積層作業も困難で手間もかかるばかりでなく、安全上の問題がある。   And the deeper the tank part is, the more easily affected by the earth pressure, but when it is tilted or collapses due to the earth pressure, these filling members must be removed and laminated again. The deeper the tank, the more difficult the laminating work becomes, and it takes time and trouble.

この発明は、かかる現況に鑑みてなされたもので、埋め戻しの際に偏土圧によって充填部材が傾いたり、崩れたりすることのない雨水等の貯留施設並びに浸透施設を提供することを目的とする。   The present invention has been made in view of the present situation, and an object thereof is to provide a storage facility and a permeation facility for rainwater and the like in which a filling member does not tilt or collapse due to uneven earth pressure during backfilling. To do.

この発明は上記目的を達成するために次のような構成とした。即ち、この発明に係る雨水等の貯留施設並びに浸透施設は、地面を掘り下げて平面方形状に形成したタンク部内に充填部材を縦横及び上下方向に積み重ねて充填部材の積層体を形成し、前記充填部材積層体の周囲を埋め戻すとともに、充填部材積層体の上を被覆してなる雨水等の貯留施設並びに浸透施設において、前記充填部材積層体は、積層充填部と連結充填部とからなり、前記積層充填部は、単体の充填部材を縦横及び上下方向に積み重ねて形成してなり、連結充填部は、枠部に中空の支柱部を複数突設してなる単体の充填部材を縦横及び上下方向に積み重ね、前記単体の充填部材の支柱部のうち少なくとも１つの支柱部が上下に連通するように形成されており、前記連通する支柱部の内部に連結材を入れることにより支柱部同士を一体に連結して形成してなり、前記連結充填部が積層充填部の偏土圧を受ける側と対向する側の外周側面又は積層充填部の内部に配設してなることを特徴とする。 In order to achieve the above object, the present invention is configured as follows. That is, the storage facility and infiltration facility for rainwater and the like according to the present invention form a stack of filling members by stacking the filling members vertically and horizontally and vertically in a tank portion formed by digging the ground into a flat rectangular shape. In a storage facility and a permeation facility for rainwater and the like that covers the periphery of the member laminate and covers the filler member laminate, the filler member laminate includes a laminate filler and a connected filler, laminated packing unit is made by forming a stack of single filling member in the vertical and horizontal directions and vertical directions, connecting the filling unit, simple vertical and horizontal and vertical filling member in which a plurality projecting hollow struts in the frame portion the stacking, at least one strut is formed so as to communicate with the upper and lower, integral struts together by putting the connecting member inside the support portion for the communication of the struts of the single filling member It is formed by connecting the connecting filling portion is characterized by being disposed within the outer peripheral side or stacked packing portion on the side facing the receiving side polarization earth pressure of laminated packing unit.

前記上下において連通する支柱部の内部に入れて支柱部同士を連結する連結材として、コンクリートを用いてもよいし、連結棒を用いてもよい。Concrete may be used or a connecting rod may be used as a connecting material that is inserted into the upper and lower supporting column portions and connects the supporting column portions.

上下に積層してなる充填部材の支柱部同士をコンクリートまたは連結棒等による連結材によって一体に連結してなるから、埋め戻しの際に偏土圧を受けてもタンク部内に縦横及び上下方向に積み重ねてなる充填部材の充填部材積層体は一体となって偏土圧を受けることになるから、前記積層体が傾いたり、崩れたりすることもない。また、安定した埋め戻し作業を行うことができるから、埋め戻し作業を安全かつ効率よく行うことができる。   Since the struts of the filling members stacked one above the other are integrally connected by a connecting material such as concrete or a connecting rod, even if it receives uneven earth pressure during backfilling, it will be vertically and horizontally and vertically in the tank part Since the filling member laminates of the filling members that are stacked are integrally subjected to the uneven earth pressure, the laminates are not tilted or collapsed. In addition, since a stable backfilling operation can be performed, the backfilling operation can be performed safely and efficiently.

以下に、この発明に係る雨水等の貯留施設並びに浸透施設の実施形態を詳細に説明する。図１は、雨水等の貯留施設並びに浸透施設の充填部材の配置を示す説明用平面図である。雨水等の貯留施設並びに浸透施設１０は、地面を掘り下げたタンク部内に充填部材が積層された積層充填部１１と、充填部材が一体に連結された連結充填部１２と、タンク部の側面との間に埋め戻された埋め戻し土１３によって構成されている。   Hereinafter, embodiments of storage facilities for rainwater and the like and penetration facilities according to the present invention will be described in detail. FIG. 1 is a plan view for explaining the arrangement of storage members for rainwater and the like and filling members of a seepage facility. The storage facility for rainwater and the infiltration facility 10 include a stacked filling portion 11 in which a filling member is laminated in a tank portion dug down the ground, a connected filling portion 12 in which the filling members are integrally connected, and a side surface of the tank portion. It is constituted by backfilling soil 13 that is backfilled in between.

前記積層充填部１１は、単体の充填部材を縦横に並列するとともに複数段に積層してなる充填部材積層体であって、単体の充填部材には従来公知のいずれの充填部材でも使用することができる。また、前記連結充填部１２は、支柱部を有する充填部材を縦横に並列するとともに上下に複数段積層して、上下において連通する支柱部同士を一体に連結してなる充填部材積層体である。このような連結充填部１２を構成する充填部材には、枠部に中空の支柱部を突設してなる充填部材であって、積層したとき支柱部の少なくとも１つが連通する充填部材を使用することができる。   The laminated filling portion 11 is a filling member laminated body in which a single filling member is arranged in a row and a plurality of stages, and any conventionally known filling member can be used as a single filling member. it can. In addition, the connecting and filling portion 12 is a filling member laminated body in which filling members having support portions are vertically and horizontally arranged and stacked in a plurality of stages in the vertical direction, and the support portions communicating in the vertical direction are integrally connected. The filling member constituting such a connected filling portion 12 is a filling member formed by projecting a hollow column portion on the frame portion, and a filling member in which at least one of the column portions communicates when stacked is used. be able to.

上下において連通する支柱部の上下には公知の固着手段を設け、この固着手段により支柱部同士を一体に連結する。上下において連通する支柱部内部に連結材を入れることによって支柱部同士をより強固に連結することができる。積層したとき連通している支柱部に入れて一体に連結する連結材としては、コンクリートを充填し又は連結棒を挿入することによって一体化することができる。コンクリートは積層した充填部材のうち連通している支柱部に充填すればよい。また、連結棒にはプラスチック製、金属製、木製等のいずれの材質であってもよく、支柱部に挿入した連結棒は、積層した充填部材の支柱部内を貫通することによって連結している。前記コンクリート又は連結棒の全部又は一部は、その下端部がタンク部の底部に固定されていることが好ましい。   A well-known fixing means is provided above and below the column parts communicating in the vertical direction, and the column parts are integrally connected by this fixing means. By placing the connecting material inside the struts communicating in the vertical direction, the struts can be more firmly coupled to each other. As the connecting material that is connected to the supporting column portion that is in communication when laminated, it can be integrated by filling concrete or inserting a connecting rod. What is necessary is just to fill concrete into the support | pillar part connected among the laminated filling members. The connecting rod may be made of any material such as plastic, metal, and wood, and the connecting rod inserted into the support column is connected by passing through the support column of the stacked filling members. It is preferable that the lower end part of all or part of the concrete or the connecting rod is fixed to the bottom part of the tank part.

図１（ａ）は、積層充填部１１の外周のうち三面にコの字状に連結充填部１２を配設した場合であり、一方側からのみ埋め戻しが可能な場合の配置図である。図１（ｂ）は、積層充填部１１の外周のうち二面にＬ字状に連結充填部１２を配設した場合であり、二方側から埋め戻しが可能な場合の配置図である。また、図１（ｃ）は、一方側からのみ埋め戻しが可能な場合に、積層充填部１１の中央部に連結充填部１２を配設した場合の配置図である。さらに、図１（ｄ）は、積層充填部１１の縦横の各中央部に連結充填部１２を配設した場合の配置図である。   FIG. 1A is a layout diagram in the case where the connecting and filling portions 12 are arranged in a U-shape on three surfaces of the outer periphery of the stacked filling portion 11 and can be backfilled only from one side. FIG. 1B is a layout diagram in the case where the connecting and filling portions 12 are arranged in an L shape on two surfaces of the outer periphery of the stacked filling portion 11 and can be backfilled from two sides. FIG. 1C is a layout diagram in the case where the connection filling portion 12 is provided at the center of the stacked filling portion 11 when backfilling is possible only from one side. Further, FIG. 1 (d) is a layout diagram in the case where the connection filling portion 12 is provided at each of the vertical and horizontal central portions of the stacked filling portion 11.

前記連結充填部１２は、縦方向において支柱部同士が連結材によって一体に連結されているとともに、全体の重量が増大するから、連結充填部１２を積層充填部１１の外周側面又は中央部に配設することによって、埋め戻しの際の矢印方向からの偏土圧に対抗して積層充填部１１の傾きや崩れを防止することができる。   The connecting and filling portion 12 is integrally connected to each other by connecting members in the vertical direction, and the overall weight increases. Therefore, the connecting and filling portion 12 is arranged on the outer peripheral side surface or the central portion of the stacked filling portion 11. By providing, it is possible to prevent the inclination and collapse of the stacked filling portion 11 against the uneven earth pressure from the arrow direction at the time of backfilling.

次に、前記連結充填部１２に用いる充填部材とその連結方法について説明する。図２に示す連結充填部１２に用いる充填部材の一例を示す斜視図である。充填部材１５は、枠部１６と支柱１８，１９とからなる。前記枠部１６は、平面長方形状の枠体１６Ａのほぼ中間部に連結桟１６Ｂを一体に設けてなり、連結桟１６Ｂで仕切られた両側の透孔に十字状桟２０を形成してなる。枠部１６の枠体１６Ａの下面には四隅部と長手方向の中間部に前記支柱部１８、１９を設けてなる。   Next, the filling member used for the connection filling part 12 and its connection method will be described. It is a perspective view which shows an example of the filling member used for the connection filling part 12 shown in FIG. The filling member 15 includes a frame portion 16 and support columns 18 and 19. The frame portion 16 is formed by integrally providing a connecting bar 16B at a substantially intermediate portion of a planar rectangular frame 16A, and formed with cross-shaped bars 20 in through holes on both sides partitioned by the connecting bar 16B. On the lower surface of the frame body 16A of the frame portion 16, the post portions 18 and 19 are provided at the four corner portions and the middle portion in the longitudinal direction.

前記枠体１６Ａ及び連結桟１６Ｂは、図示する実施形態では、板状体によって形成されているが、下面に補強リブを設ける構造であってもよく、複数の透孔を形成した格子状構造であってもよく、その他任意の公知構造とすることができる。   In the illustrated embodiment, the frame body 16A and the connecting bar 16B are formed of a plate-like body. However, the frame body 16A and the connecting bar 16B may have a structure in which reinforcing ribs are provided on the lower surface, or a lattice-like structure in which a plurality of through holes are formed. There may be other arbitrary well-known structures.

また、枠体１６Ａの四隅の下面に突設された支柱部１８、枠体１６Ａの長手方向のほぼ中間部の下面に突設された支柱部１９は、四角形中空構造に形成されている。支柱１８，１９の上面は、枠体１６Ａに開口しているとともに、下面も開口しているから上下面は貫通している。従って、雨水は、支柱部１８，１９の内部にも流入することになり、それだけ、雨水の貯留量を大きくすることができるとともに、支柱部１８，１９は、コンクリートを充填し又は連結棒を挿入して一体化する支柱部として利用することができる。   Further, the support column 18 projecting from the lower surface of the four corners of the frame 16A and the support column 19 projecting from the lower surface of the substantially intermediate portion in the longitudinal direction of the frame 16A are formed in a rectangular hollow structure. The upper surfaces of the columns 18 and 19 are open to the frame body 16A, and the lower surfaces are also open, so that the upper and lower surfaces penetrate. Therefore, rainwater also flows into the inside of the column parts 18 and 19, so that the storage amount of rainwater can be increased, and the column parts 18 and 19 are filled with concrete or a connecting rod is inserted. And can be used as a column part to be integrated.

前記支柱部１８，１９の断面形状は、四角形に限定されるものではなく、円形、楕円形、三角形等任意の形状とすることができる。さらに、図示する実施形態では、枠部１６と支柱部１８、１９とを一体に形成しているが、着脱自在な組み立て式に形成してもよい。組み立て式充填部材は、例えば、枠部１６の下面に支柱部１８，１９と断面が同形状の嵌合突部を設けておき、この突部を支柱部１８、１９の上端開口部に嵌合させる構成とすればよい。   The cross-sectional shape of the support columns 18 and 19 is not limited to a quadrangle, and may be any shape such as a circle, an ellipse, or a triangle. Furthermore, in the illustrated embodiment, the frame portion 16 and the column portions 18 and 19 are integrally formed, but they may be formed in a detachable assembly type. For example, the assembly type filling member is provided with a fitting protrusion having the same cross section as that of the support pillars 18 and 19 on the lower surface of the frame part 16, and this protrusion is fitted to the upper end openings of the support pillars 18 and 19. What is necessary is just to make it the structure made to do.

次に、枠部１６と支柱部１８，１９との関係について説明すると、枠部１６の長手方向の長さ寸法Ｌ１は、短手方向の幅寸法Ｌ２の約２倍である。即ち、Ｌ１≒２Ｌ２の関係にある。そして、支柱部１８、１９は同一寸法の大きさに形成されていることが好ましい。   Next, the relationship between the frame portion 16 and the support column portions 18 and 19 will be described. The length dimension L1 in the longitudinal direction of the frame portion 16 is about twice the width dimension L2 in the lateral direction. That is, there is a relationship of L1≈2L2. And it is preferable that the support | pillar parts 18 and 19 are formed in the magnitude | size of the same dimension.

また、図３は、図１に示す実施形態の変形例である第２実施形態を示し、充填部材２３は、枠部２４と支柱２５，２６とからなる。前記枠部２４は、平面長方形状の枠体２４Ａのほぼ中間部に連結桟２４Ｂを一体に設けてなり、連結桟２４Ｂで仕切られた両側に透孔２４Ｃを形成してなる。枠部２４の枠体２４Ａの下面には四隅部と長手方向の中間部に支柱部２５、２６を設けてなる。支柱部２６は、隅間を設けて並列した支柱２６Ａ，２６Ａからなる。   FIG. 3 shows a second embodiment which is a modification of the embodiment shown in FIG. 1, and the filling member 23 includes a frame portion 24 and support columns 25 and 26. The frame portion 24 is formed by integrally providing a connecting bar 24B substantially at an intermediate portion of a planar rectangular frame 24A, and has through holes 24C formed on both sides partitioned by the connecting bar 24B. On the lower surface of the frame body 24A of the frame portion 24, support portions 25 and 26 are provided at the four corner portions and the middle portion in the longitudinal direction. The column part 26 is composed of columns 26A and 26A arranged in parallel with a space between the corners.

支柱部２６は、隅間を設けて並列した支柱２６Ａ，２６Ａとすることによって、両者の隙間の部分から連結桟２４Ｂを二分割することによって充填部材２３を半分に分割することができる。このように、充填部材２３を二分割可能な大きさとする場合には、枠体２４Ａの長手方向の長さ寸法Ｌ３を短手方向の幅寸法Ｌ４の約２倍とし、Ｌ３≒２Ｌ４とする。   The support | pillar part 26 can divide the filling member 23 in half by dividing | segmenting the connection bar | burr 24B into two from the part of the clearance gap between the support | pillar part 26A and 26A which provided the space between corners and was parallel. Thus, when the filling member 23 has a size that can be divided into two, the length L3 in the longitudinal direction of the frame body 24A is approximately twice the width L4 in the short direction, and L3≈2L4.

次に、上記充填部材１５、２３の使用方法について説明する。充填部材１５、２３は、地中に形成されたタンク部に縦横に並べられ、かつ上下に段積みすることによって充填され、図１に示す連結充填部１２を形成することになる。   Next, the usage method of the said filling members 15 and 23 is demonstrated. The filling members 15 and 23 are arranged vertically and horizontally in a tank portion formed in the ground, and are filled by stacking up and down to form the connected filling portion 12 shown in FIG.

連結充填部１２を形成するには、図４及び図５に示すように、同一方向に並べられた下段の充填部材１５，１５又は充填部材２３，２３上に、上段の充填部材１５、２３を９０度方向を変えて井桁状に段積みし、さらにその上に充填材１５，１５又は充填部材２３，２３を９０度方向を変えて井桁状に順次段積みすればよい。このようにして、縦横に並べられた下段の充填材の上に井桁状に積み重ねることによって安定した状態で積み重ねることができる。   4 and 5, the upper filling members 15, 23 are placed on the lower filling members 15, 15 or the filling members 23, 23 arranged in the same direction. What is necessary is just to stack | stack the fillers 15 and 15 or the filling members 23 and 23 on it further in the shape of a cross, changing a 90 degree direction, and also changing the 90 degree direction. In this way, it is possible to stack in a stable state by stacking in a cross-beam shape on the lower packing material arranged vertically and horizontally.

井桁状に段積みされた充填部材１５の支柱部１８，１９または充填部材２３の支柱部２５，２６は上下方向に連通している部分があるから、これらの連通している支柱部の全部又は一部にコンクリートを充填し又は連結棒を挿入することによって一体化すれば連結充填部１２とすることができる。   Since the column portions 18, 19 of the filling member 15 or the column portions 25, 26 of the filling member 23 that are stacked in the form of a cross-beam have a portion that communicates in the vertical direction, all of these communicating column portions or If a part is filled with concrete or it integrates by inserting a connecting rod, it can be set as the connection filling part 12. FIG.

図６は、充填部材１５を井桁状に段積みしたとき、上下に連通する支柱部１８にコンクリートＣを充填して一体に連結し、連結充填部１２を形成した場合の一部要部断面図である。充填されたコンクリートＣによって支柱部１８、１８が一体に連結されている。連通する支柱部１８には、コンクリートＣに代えて連結棒を挿入して連結してもよい。支柱部１８に充填したコンクリート又は支柱部１８に挿入した連結棒の全部又は一部は、その下端部がタンク部１の底部２に固定されていることが好ましい。   FIG. 6 is a partial cross-sectional view of the main part when the filling member 15 is stacked in a cross-beam shape and the concrete filling portion 12 is integrally connected to the supporting column portion 18 communicating with the upper and lower sides to form a connected filling portion 12. It is. The column portions 18, 18 are integrally connected by the filled concrete C. Instead of the concrete C, a connecting rod may be inserted and connected to the communicating column 18. It is preferable that the lower end portion of the concrete filled in the support column 18 or the whole or a part of the connecting rod inserted in the support column 18 is fixed to the bottom 2 of the tank unit 1.

図７は、連結充填部１２に用いる充填部材の第３の実施形態を示す。図７に示す充填部材３０は、略正方形の枠部３０Ａと、枠部３０Ａの対角線方向に沿って斜めに交差することで枠部３０Ａの内側を相互に連結する複数のリブ３０Ｂと、枠部３０Ａの４隅部分及び各リブ３０Ｂの交差部分から下方に突出する複数本の支柱部３０Ｃとを有する。   FIG. 7 shows a third embodiment of the filling member used for the connected filling portion 12. The filling member 30 shown in FIG. 7 includes a substantially square frame portion 30A, a plurality of ribs 30B that mutually connect the inside of the frame portion 30A by crossing diagonally along the diagonal direction of the frame portion 30A, and the frame portion. 30A, and four pillar portions 30C protruding downward from the intersecting portions of the ribs 30B.

充填部材３０の各支柱部３０Ｃは、小径の嵌合部３０Ｄを下端部に有する段付きパイプ状に形成されており、各支柱部３０Ｃの上面は開口している。従って、段積みしたときに、下段の充填部材３０の上面の開口に、上段の充填体３０の各支柱部３０Ｃの嵌合部３０Ｄが嵌合する。このため、複数の充填部材３０は、各支柱部３０Ｃの上面開口に嵌合部３０Ｄを嵌合させることで、上下に安定的に積み重ねることができる。   Each column portion 30C of the filling member 30 is formed in a stepped pipe shape having a small-diameter fitting portion 30D at the lower end portion, and the upper surface of each column portion 30C is open. Therefore, when stacked, the fitting portions 30 </ b> D of the support column portions 30 </ b> C of the upper filling body 30 are fitted into the openings on the upper surface of the lower filling member 30. For this reason, the some filling member 30 can be piled up and down stably by making fitting part 30D fit in the upper surface opening of each support | pillar part 30C.

そして、上下に積み重ねられた充填部材３０の支柱部３０Ｃは、図８に示すように上下方向に連通しているから、これらの支柱部の全部又は一部にコンクリートを充填し又は連結棒を挿入することによって連結充填部１２とすることができる。支柱部に充填したコンクリート又は支柱部に挿入した連結棒の全部又は一部は、その下端部がタンク部の底部２に固定されていることが好ましい。   And since the support | pillar part 30C of the filling member 30 stacked | piled up and down is communicating in the up-down direction as shown in FIG. 8, all or one part of these support | pillar parts is filled with concrete, or a connecting rod is inserted. By doing so, it can be set as the connection filling part 12. It is preferable that the lower end part of the concrete filled in the column part or the connecting rod inserted into the column part is fixed to the bottom part 2 of the tank part.

なお、連結充填部１２を形成する充填部材は、上記実施形態に限定されるものではなく、積み重ねたとき上下に連通する支柱部を有する充填部材であればよい。例えば、基盤の一方の側から１つの支柱部を延在させた充填部材であってもよい。   In addition, the filling member which forms the connection filling part 12 is not limited to the said embodiment, What is necessary is just a filling member which has a support | pillar part connected up and down when it accumulates. For example, it may be a filling member in which one strut portion extends from one side of the base.

一方、積層充填部１１を形成する充填部材は、連結充填部に使用する充填部材であってもよく、その他の公知の充填部材であってもよい。積層充填部１１を形成する充填部材に連結充填部１２と同一の充填部材を用いた場合には、一体に連結する必要はないから連通する支柱部にコンクリートを充填したり、連結棒を挿入するのを省略すればよい。また、積層充填部１１を形成する充填部材として、他の公知の充填部材を用いた場合には、その充填部材の通りに積み重ねればよい。   On the other hand, the filling member forming the stacked filling portion 11 may be a filling member used for the connected filling portion, or may be another known filling member. When the same filling member as the connecting filling portion 12 is used as the filling member forming the laminated filling portion 11, it is not necessary to connect them together, so that the communicating strut portions are filled with concrete or a connecting rod is inserted. Can be omitted. Moreover, what is necessary is just to pile up according to the filling member, when other well-known filling members are used as a filling member which forms the lamination | stacking filling part 11. FIG.

積層充填部１１を形成する充填部材としては、例えば、図９(ａ)に示すように側壁が底部に向って小さくなるテーパー状に構成した容器状充填体３３、図９(ｂ)に示すように平板を複数の連続する山型に折り曲げ、山頂部と谷部に嵌合部を設けた充填体３４、あるいは図９(ｃ)に示すように矩形の傾斜板の上下に連結部を設けた充填体３５であってもよい。   As the filling member forming the stacked filling portion 11, for example, as shown in FIG. 9 (a), a container-like filling body 33 having a tapered shape in which the side wall becomes smaller toward the bottom, as shown in FIG. 9 (b). The flat plate is bent into a plurality of continuous chevron shapes, and a filler 34 provided with fitting portions at the crest and trough portions, or connecting portions are provided above and below a rectangular inclined plate as shown in FIG. The filler 35 may be used.

このように、積層充填部１１を単体の充填部材を縦横に並列するとともに複数段に積層してなる充填部材積層体とした場合でも、積層してなる充填部材の一部が縦方向において一体に連結してなる充填部材積層体である連結充填部１２を前記積層充填部１１の外周側面又は中央部に配設することによって、埋め戻しの際の偏土圧に対抗して積層充填部１１の傾きや崩れを防止することができる。また、連結充填部１２は、地震や大型車両の走行時に発生する横揺れ対策にも有効であるから、雨水等の貯留施設並びに浸透施設の耐震性能が向上する。   As described above, even when the laminated filling portion 11 is a filling member laminated body in which single filling members are arranged in parallel in the vertical and horizontal directions, a part of the laminated filling members is integrated in the vertical direction. By connecting the connecting and filling portion 12 which is a connecting member laminated body formed on the outer peripheral side surface or the central portion of the stacked filling portion 11, the uneven filling pressure of the stacked filling portion 11 is counteracted against the earth pressure at the time of backfilling. Tilt and collapse can be prevented. Moreover, since the connection filling part 12 is effective also in the countermeasure against the rolling which generate | occur | produces at the time of driving | running | working of an earthquake or a large vehicle, the seismic performance of storage facilities, such as rainwater, and an infiltration facility improves.
