Description

本発明は、横穴墓空洞部の充填工法に関するものである。   The present invention relates to a filling method for a side hole tomb cavity.

横穴墓とは、古墳時代後期に多く作られた墓であり、具体的には、急な斜面に対して水平な穴を掘った墓で、高さ約3m×幅約3m×奥行き5mサイズの空洞部からなる横穴墓が数多く存在する。   A horizontal tomb is a tomb made in the latter half of the Kofun period. Specifically, it is a tomb dug in a horizontal hole on a steep slope, measuring 3m in height, 3m in width, and 5m in depth. There are many side-hole tombs consisting of hollow parts.

そして最近では、その横穴墓空洞部の風化を抑制すること、および崩落等による災害を防ぐために、この横穴墓空洞部を埋め戻すようになってきた。その埋め戻す方法としては、先ず横穴墓空洞部に発泡スチレンブロックを敷き詰め、その後、該発泡スチレンブロックと横穴墓空洞部の壁面や天井面とで形成された隙間に、発泡モルタルを注入し発泡充填させ、その後、同様の作業を繰り返して、横穴墓空洞部を充填する工法が採用されていた。   Recently, in order to suppress the weathering of the side hole tomb cavity and prevent disasters caused by collapse, the side hole tomb cavity has been refilled. As a backfilling method, first, a foamed styrene block is laid in the side hole tomb cavity, and then foamed mortar is injected into the gap formed between the foamed styrene block and the wall surface or ceiling surface of the side hole tomb cavity. After that, the same work was repeated and the method of filling the side hole tomb cavity was adopted.

一方、軽量盛土工法として、特許文献1に記載されているような地盤表面にポリウレタンと親和性を有する防水プライマーを形成後、第一層目の硬質合成樹脂発泡体ブロックを敷き詰め、地盤と該ブロック層との隙間に所定量の硬質発泡ポリウレタン形成用組成物を注入し、第一層目の高さ位置まで発泡充填し、ついで第二層目以降を同様の作業を繰り返すことを特徴とする軽量盛土工法が記載されている。
特許第2775693号公報
On the other hand, as a lightweight embankment method, after forming a waterproof primer having affinity with polyurethane on the ground surface as described in Patent Document 1, a hard synthetic resin foam block of the first layer is spread, and the ground and the block Light weight characterized by injecting a predetermined amount of hard foamed polyurethane forming composition into the gap with the layer, filling the foam up to the height of the first layer, and then repeating the same work for the second and subsequent layers The embankment method is described.
Japanese Patent No. 2775693

しかしながら、前者には次のような問題があった。横穴墓空洞部は、入り口の高さよりも奥の方が高くなっているものがあり、その様な高い場所にて発泡モルタルを注入すると、その発泡モルタルは流動性が高いため、その高い場所から低い場所へと発泡モルタルが流れ込んでしまい、所定位置にて発泡充填させることが困難であった。その結果、横穴墓空洞部に隙間が生じ、横穴墓空洞部の天井部や壁面部の土砂が崩れ、横穴墓の風化を抑制すること、および崩落を防ぐことが出来ない虞があった。   However, the former has the following problems. Some of the side hole grave cavities are higher in the back than the entrance height, and when foamed mortar is injected at such a high place, the foamed mortar has high fluidity. The foamed mortar flowed into a low place, and it was difficult to foam and fill at a predetermined position. As a result, a gap was generated in the side hole tomb cavity, and the earth and sand of the ceiling and wall surface of the side hole tomb cavity collapsed, and there was a possibility that weathering of the side hole tomb was suppressed and collapse could not be prevented.

そこで、横穴墓空洞部の入り口よりも高くなっている場所を充填する場合、発泡モルタルが所定位置にて充填させるように型枠を組み、その高い場所から低い場所へと発泡モルタルが流れ込むのを防止する手段が考えられたが、横穴墓空洞部は、狭い空間であるためその様な型枠の組み立てには、時間と手間が掛かるものであり、施工性に問題があった。   Therefore, when filling a place that is higher than the entrance of the side hole tomb cavity, form a mold so that the foam mortar fills in place, and the foam mortar flows from the high place to the low place. Although the means to prevent it was considered, since the side hole grave cavity is a narrow space, it takes time and labor to assemble such a formwork, and there was a problem in workability.

また、後者の工法を横穴墓空洞部の充填工法に転用した場合、次のような問題があった。横穴墓空洞部の表面は、土や砂や石等からなるもので、しかも凹凸が激しいものであった。したがって、後者のように防水性を有するプライマー、具体的には合成樹脂からなるプライマーでは、確かに防水性は得られるものの、横穴墓空洞部の表面、すなわち、該空洞部の床面・壁面・天井面との追随性が悪く、密着性がよくない問題があった。その結果、該プライマーと該空洞部の床面・壁面・天井面との間に隙間が生じ、風化を抑制すること及び崩落等を防ぐことが出来ない虞があった。   Moreover, when the latter method was diverted to the filling method for the side hole grave cavity, there were the following problems. The surface of the cave tomb was made of earth, sand, stone, etc., and was uneven. Therefore, with the latter primer having waterproofness, specifically, a primer made of synthetic resin, although waterproofness is surely obtained, the surface of the side hole tomb cavity, that is, the floor surface, wall surface, There was a problem that the followability with the ceiling surface was poor and the adhesion was not good. As a result, there are gaps between the primer and the floor surface, wall surface, and ceiling surface of the cavity, and there is a possibility that weathering cannot be suppressed and collapse cannot be prevented.

本発明は、かかる従来技術の課題に鑑みてなされたもので、横穴墓空洞部に隙間なく充填材を充填することが出来る充填工法を提供することを目的としたものである。   This invention is made | formed in view of the subject of this prior art, and it aims at providing the filling construction method which can be filled with a filler without a clearance gap in a horizontal hole grave cavity part.

本発明の請求項1に記載の横穴墓空洞部の充填工法は、横穴墓空洞部の表面に和紙を貼り付けた後、第一層目の発泡スチレンブロックを敷き詰め、横穴墓空洞部の壁面と端部の発泡スチレンフロックとで形成された隙間に、現場発泡硬質ポリウレタンフォームを注入し第一層目の発泡スチレンブロックの高さまで発泡充填し、ついで上記同様の作業を・・・第n段目まで繰り返し、最上段目であるn段目においては、横穴墓空洞部の天井面と発泡スチレンブロックとで形成された隙間に、現場発泡硬質ポリウレタンフォームを注入し該天井面の高さまで発泡充填したことを特徴とする。   According to claim 1 of the present invention, the filling method for the side hole tomb cavity part is a method of pasting Japanese paper on the surface of the side hole tomb cavity part, then laying a first layer of foamed styrene block, In-situ foamed rigid polyurethane foam is injected into the gap formed with the foamed styrene flock at the end and foamed and filled to the height of the foamed styrene block of the first layer. In the n-th stage, which is the uppermost stage, in-situ foamed rigid polyurethane foam is injected into the gap formed by the ceiling surface of the hollow grave cavity and the foamed styrene block, and the foam is filled to the height of the ceiling surface. It is characterized by that.

また、本発明の請求項2に記載の横穴墓空洞部の充填工法は、前記隙間が、水平方向における最大幅で15cm以下であることを特徴とするものである。   Moreover, the filling method of the side hole grave cavity part of Claim 2 of this invention is characterized by the said clearance gap being 15 cm or less at the maximum width in a horizontal direction.

本発明の横穴墓の空洞充填工法によれば、横穴墓空洞部に隙間なく充填材を充填することが出来るので、その横穴墓空洞部の風化を抑制すること、および崩落等による災害を防ぐことが出来る。さらに、充填後、充填前の状態に復帰することが可能である。   According to the cavity filling method of the side hole tomb of the present invention, the filling material can be filled into the side hole tomb cavity without gaps, so that weathering of the side hole tomb cavity can be suppressed and disasters caused by collapse etc. can be prevented. I can do it. Furthermore, it is possible to return to the state before filling after filling.

以下に、本発明の横穴墓空洞部の充填工法の一実施形態について、図面を参照しながら説明する。   Below, one Embodiment of the filling method of the side hole grave cavity part of this invention is described, referring drawings.

本発明の横穴墓空洞部の充填工法は、横穴墓空洞部の表面に和紙を貼り付けた後、第一層目の発泡スチレンブロックを敷き詰め、横穴墓空洞部の壁面と端部の発泡スチレンフロックとで形成された隙間に、現場発泡硬質ポリウレタンフォームを注入し第一層目の発泡スチレンブロックの高さまで発泡充填し、ついで上記同様の作業を・・・第n段目まで繰り返し、最上段目であるn段目においては、横穴墓空洞部の天井面と発泡スチレンブロックとで形成された隙間に、現場発泡硬質ポリウレタンフォームを注入し該天井面の高さまで発泡充填したことを特徴とするものであり、この充填工法により完成されたものが図2であり、その断面図が図3である。なお、他の実施例として、図4の断面図に示すような横穴墓空洞部もある。   The filling method of the horizontal hole grave cavity of the present invention is the method of filling Japanese paper on the surface of the horizontal hole grave cavity, then laying the first layer of foamed styrene block, and the expanded styrene flock on the wall and end of the horizontal hole grave cavity In-situ foamed rigid polyurethane foam is injected into the gap formed by filling the foamed foam to the height of the first layer of foamed styrene block, then the same operation as above is repeated until the nth stage, the top stage In the n-th stage, in-situ foamed rigid polyurethane foam is injected into the gap formed by the ceiling surface of the hollow grave cavity and the foamed styrene block, and the foam is filled to the height of the ceiling surface. FIG. 2 is a view completed by this filling method, and FIG. 3 is a sectional view thereof. As another embodiment, there is a side hole tomb cavity as shown in the sectional view of FIG.

また、図3や図4に示すように、横穴墓空洞部1を前記のように充填した後、横穴墓空洞部の入り口8全面を現場発泡硬質ポリウレタンフォーム7にて覆い、その現場発泡硬質ポリウレタンフォーム7上面に樹脂モルタルを塗って完成させてもよい。   Further, as shown in FIGS. 3 and 4, after filling the side hole tomb cavity 1 as described above, the entire entrance 8 of the side hole tomb cavity is covered with the in-situ foamed rigid polyurethane foam 7, and the in-situ foamed rigid polyurethane is covered. The top surface of the foam 7 may be completed by applying a resin mortar.

本発明は、先ず図1(a)に示すように、横穴墓空洞部1の表面全面にふのりを塗って和紙2を貼り付けるものである。和紙2は、横穴墓空洞部1の表面が凸凹であっても、その表面に追随することができ、つまり密着性がよいものである。その結果、その表面に対して隙間なく和紙2を貼り付けることができ、しかも、経時で和紙2がその表面から剥がれ難いものである。その上、和紙2は柔軟性に優れるので、その表面を傷付けることがなく、また和紙以外の充填材(敷砂、発泡スチレンブロック、現場発泡硬質ポリウレタンフォーム)を充填させた際、その表面に傷が付くのを防止する、すなわち保護層としての役割も担うものである。   In the present invention, first, as shown in FIG. 1 (a), the Japanese paper 2 is pasted by applying a cover to the entire surface of the side hole tomb cavity 1. The Japanese paper 2 can follow the surface of the side hole grave cavity 1 even if the surface thereof is uneven, that is, has good adhesion. As a result, the Japanese paper 2 can be affixed to the surface without a gap, and the Japanese paper 2 is difficult to peel off from the surface over time. In addition, Japanese paper 2 has excellent flexibility so that its surface is not damaged, and when it is filled with a filler other than Japanese paper (laying sand, foamed styrene block, in-situ foamed rigid polyurethane foam), the surface is scratched. This prevents the film from sticking, that is, plays a role as a protective layer.

また、横穴墓空洞部1の表面全面に和紙2を貼り付けられるものであれば、ふのり以外の接着剤等を使用してもよいが、ふのりは和紙2を該横穴墓空洞部1の表面に貼り付ける事ができ、かつ剥がす事が容易に出来る。その結果、横穴墓空洞部1に上記充填材を充填した後、充填前の状態に復帰する必要があった場合、容易に復帰することが出来る。
次に、図1(b)に示すように、床面3aが平らになるように敷砂4を敷く。敷砂4は、床面3aを平らにし、次に敷き詰める発泡スチレンブロックを設置し易くすることができ、かつ、複数の発泡スチレンブロックを敷き詰めた場合、水平方向の該ブロック同士の目地部において、隙間が生じるのを防ぐことが出来る。
In addition, as long as the Japanese paper 2 can be pasted on the entire surface of the side hole tomb cavity 1, an adhesive other than furan may be used. Can be pasted and easily peeled off. As a result, when it is necessary to return to the state before filling after filling the above-mentioned filling material into the side hole grave cavity portion 1, it can be easily returned.
Next, as shown in FIG. 1B, the spread sand 4 is laid so that the floor surface 3a is flat. The spread sand 4 can flatten the floor surface 3a, and can easily install a foam styrene block to be spread next, and when a plurality of foam styrene blocks are spread, in the joint portion between the horizontal blocks, A gap can be prevented from being generated.

また、床面3aを平らに出来るものであれば敷砂以外の例えば土や石、合成樹脂発泡体、それらを粉砕したもの等を単独、或いは複数併用したものを敷いてもよい。   Further, as long as the floor surface 3a can be flattened, for example, soil or stone, synthetic resin foam, those obtained by pulverizing them, or a combination of a plurality of them may be laid.

次に、図1(c)に示すように、その敷砂4上に第一層目の発泡スチレンブロック5aを敷き詰める。この際、複数の発泡スチレンブロックを敷き詰める場合、水平方向の該ブロック同士の目地部において、隙間が生じないように敷き詰めるものである。   Next, as shown in FIG. 1 (c), a first layer of expanded styrene block 5 a is spread on the spread sand 4. At this time, when a plurality of foamed styrene blocks are spread, the gaps are spread so as not to form gaps in the joint portions between the horizontal blocks.

さらに、図1(c)に示すように、端部の発泡スチレンブロック5aと壁面3bとで形成された隙間6aが、水平方向における最大幅で15cm以下になるように発泡スチレンブロック5aを敷き詰めることが好ましい。この隙間6aが15cmを超えてしまうと、この隙間6aに現場発泡硬質ポリウレタンフォーム7aを注入し発泡充填させた際、その現場発泡硬質ポリウレタンフォーム7aの発泡時における反応熱が高くなり、その結果、発泡スチレンブロック5aが溶けて形状が変形してしまう虞がある。なお、以下に示すように、発泡スチレンブロック5a〜5nと壁面3bとで形成された隙間6a〜6n、および発泡スチレンブロック5nと天井面3cとで形成された隙間6においても、最大で15cm以下の隙間となるように発泡スチレンブロック5a〜5nを敷き詰めることが好ましい。なお、発泡スチレンブロック同士を固定する手段として、金具を使用してもよい。   Further, as shown in FIG. 1 (c), the foamed styrene block 5a is spread so that the gap 6a formed by the foamed styrene block 5a at the end and the wall surface 3b has a maximum width of 15 cm or less in the horizontal direction. Is preferred. When this gap 6a exceeds 15 cm, when the in-situ foamed rigid polyurethane foam 7a is injected into the gap 6a and filled with foam, the reaction heat at the time of foaming of the in-situ foamed rigid polyurethane foam 7a is increased. There is a possibility that the foamed styrene block 5a is melted and its shape is deformed. As shown below, the gaps 6a to 6n formed by the foamed styrene blocks 5a to 5n and the wall surface 3b and the gap 6 formed by the foamed styrene block 5n and the ceiling surface 3c are also 15 cm or less at maximum. It is preferable to spread the foamed styrene blocks 5a to 5n so as to form a gap. In addition, you may use a metal fitting as a means to fix foaming styrene blocks.

本発明の発泡スチレンブロック5a〜5nは、直方体或いは立方体からなるブロック状のものであればよく、その大きさについては特に限定されるものではないが、基本寸法は2000(長さ)×1000(幅)×500(高さ)mm角の直方体のものである。   The foamed styrene blocks 5a to 5n of the present invention may be in the form of a block made of a rectangular parallelepiped or a cube, and the size is not particularly limited, but the basic dimension is 2000 (length) x 1000 ( It is a rectangular parallelepiped of (width) × 500 (height) mm square.

また、端部の発泡スチレンブロック5a〜5nと壁面3bとで形成された隙間6a〜6nは、水平方向における最大幅で15cm以下となるようにすることが好ましく、現場において例えば簡易ニクロム熱線カッター等を使用して端部の発泡スチレンブロックをカットし、寸法変更させてから敷き詰めることが出来る。   Further, the gaps 6a to 6n formed by the foamed styrene blocks 5a to 5n and the wall surface 3b at the end are preferably 15 cm or less at the maximum width in the horizontal direction. Can be used to cut the foamed styrene block at the end and change the dimensions before spreading.

次に、図1(d)に示すように、壁面3bと端部の発泡スチレンフロック5aとで形成された隙間6aに、現場発泡硬質ポリウレタンフォーム7aを注入し、第一層目の発泡スチレンブロック5aの高さまで発泡充填させる。この現場発泡硬質ポリウレタンフォームは、和紙と発泡スチレンブロックに対する密着性がよく、また、該硬質ポリウレタンフォームの発泡時、和紙を通り抜けて横穴墓空洞部1の表面に貼り付く虞はなく、仮に貼り付いたとしても、この表面を破損させることなく、さらには簡単に剥がすことが出来る。   Next, as shown in FIG. 1 (d), in-situ foamed rigid polyurethane foam 7a is injected into the gap 6a formed by the wall surface 3b and the foamed styrene flock 5a at the end, and the first layer of foamed styrene block is injected. Foam filled to a height of 5a. This in-situ foamed rigid polyurethane foam has good adhesion to the Japanese paper and the foamed styrene block, and when foaming the hard polyurethane foam, there is no risk of passing through the Japanese paper and sticking to the surface of the side hole tomb cavity 1, but temporarily sticking Even if this is the case, the surface can be easily removed without damaging the surface.

この現場発泡硬質ポリウレタンフォームは、例えばポリオール成分に、ポリオール、触媒、減粘剤、難燃剤、発泡剤等が配合され、これとポリイソシアネート成分が混合されて発泡・硬化され、JIS−A9526に準拠した密度を30〜50kg/m、JIS−K7220に準拠した1%歪時の圧縮強度を約5N/cm以上のものが好ましい。 This in-situ foamed rigid polyurethane foam contains, for example, a polyol component, a polyol, a catalyst, a viscosity reducing agent, a flame retardant, a foaming agent, etc., and this is mixed with a polyisocyanate component and foamed and cured, in accordance with JIS-A9526. It is preferable that the density is 30 to 50 kg / m 3 and the compressive strength at 1% strain based on JIS-K7220 is about 5 N / cm 2 or more.

また、ポリオールはエステル型とエーテル型があるが、耐久性、特に耐加水分解性の点からポリエーテルポリオールが好適に用いられる。ポリイソシアネート成分としては特に制限されないが、一般にはクルードMDI等の有機ジイソシアネートが用いられる。発泡剤としては、特に制限されないが、水を100%使用し、フロンを併用しない方が環境対策上好ましい。   Moreover, although there exist ester type and ether type | mold, a polyol is used suitably from the point of durability, especially hydrolysis resistance. Although it does not restrict | limit especially as a polyisocyanate component, Generally organic diisocyanate, such as crude MDI, is used. Although it does not restrict | limit especially as a foaming agent, It is preferable on an environmental measure to use 100% of water and not using CFCs together.

次に、図1(e)に示すように、第二層目の発泡スチレンブロック5bを敷き詰め、その後、図1(f)に示すように壁面3bと端部の発泡スチレンブロック5bとで形成された隙間7bに、現場発泡硬質ポリウレタンフォーム7bを注入し第二層目の発泡スチレンブロック5bの高さまで発泡充填させ、その後、第三段目、第四段目・・・第n段目まで同様の作業を繰り返し、最上段目であるn段目においては、天井面3cと発泡スチレンブロック5nとの隙間に、現場発泡硬質ポリウレタンフォームを注入し発泡充填させて、図2に示すように、横穴墓空洞部1を隙間なく充填させた。   Next, as shown in FIG. 1 (e), a second layer of foamed styrene block 5b is spread, and then, as shown in FIG. 1 (f), a wall surface 3b and an end of foamed styrene block 5b are formed. The in-situ foamed rigid polyurethane foam 7b is injected into the gap 7b and foamed and filled up to the height of the foamed styrene block 5b of the second layer, and then the third stage, the fourth stage, and so on up to the nth stage. In the n-th stage, which is the uppermost stage, in-situ foamed rigid polyurethane foam is injected into the gap between the ceiling surface 3c and the foamed styrene block 5n and foam-filled.
