Description

本発明は雨水貯留構造用部材とこれを用いた雨水貯留構造物に関し、詳しくは、所定長さを有する複数の樹脂製パイプ状縦部材と、これらパイプ状縦部材を連結可能にする接続部材とを有する雨水貯留構造用部材とこれを用いた雨水貯留構造物に関する。   The present invention relates to a rainwater storage structure member and a rainwater storage structure using the same, and in particular, a plurality of resin pipe-like vertical members having a predetermined length, and a connection member that enables connection of these pipe-like vertical members; The present invention relates to a rainwater storage structure member having a stormwater storage structure and a rainwater storage structure using the same.

近年、特に都市部で異常降雨や出水、あるいはその逆の異常乾燥といった問題が頻繁に生じており、その原因としてヒートアイランド現象が取り上げられている。かかる現象を緩和するため、雨水を利用する施設の構築が提案されており、雨水貯留構造物あるいは雨水貯留用充填材などの開発が進んでいる。   In recent years, particularly in urban areas, problems such as abnormal rainfall and flooding, and vice versa, have frequently occurred, and the cause is the heat island phenomenon. In order to alleviate this phenomenon, the construction of facilities that use rainwater has been proposed, and development of rainwater storage structures or rainwater storage fillers has been progressing.

このような雨水貯留構造物として、例えば、地面にピットを堀り、その外表面に遮水シートを敷設して、その上面に複数の容器状部材を縦横および上下に積み上げ、更に最上部に覆土などを施して被覆し、雨水を貯留する構造物の発明がなされている（特許文献１）。   As such a rainwater storage structure, for example, a pit is dug in the ground, a water shielding sheet is laid on the outer surface, a plurality of container-like members are stacked vertically and horizontally, and a top cover is covered with soil. The invention of the structure which gives and coats etc. and stores rainwater is made | formed (patent document 1).

あるいは、中空体である複数の着脱自在支柱を、連結部材によって垂直に固定してなる雨水貯留用充填材であって、連結部材が着脱自在の連結桟および縁枠により一体的に連結する等して、運搬中における隅部での支柱の脱落を防止できるようにした発明がなされている（特許文献２）。
特開昭６３−２６８８２３号公報 特開２００４−１９２０５号公報 Alternatively, it is a rainwater storage filler in which a plurality of detachable support columns which are hollow bodies are vertically fixed by a connecting member, and the connecting member is integrally connected by a detachable connecting bar and an edge frame. Thus, an invention has been made that can prevent the column from dropping off at the corner during transportation (Patent Document 2).
JP-A 63-268823 JP 2004-19205 A

しかしながら、上記実施形態の雨水貯留構造物あるいは雨水貯留用充填材は、容器状部材や着脱自在支柱と連結部材とからなる雨水貯留用充填材を使用しており、点検用の十分な広さの開口部が形成されていないため、保守点検は実質上できず、永年の使用により土砂が蓄積して所定の機能を発揮し得なくなった場合にも、清掃作業は容易でなく、機能を復帰させることはできない。   However, the rainwater storage structure or the rainwater storage filler according to the above embodiment uses a rainwater storage filler composed of a container-like member, a detachable support column and a connecting member, and has a sufficiently wide area for inspection. Since the opening is not formed, maintenance and inspection is practically impossible, and even if soil accumulates due to long-term use and the specified function cannot be performed, the cleaning work is not easy and the function is restored. It is not possible.

のみならず、上記従来技術の容器状部材や充填材を運搬する場合は、これらが雨水を貯留するための大きな空間を内蔵して嵩張るため、搬送量の割に輸送コストが高くかかるという問題がある。しかも、これらの容器状部材や充填材は形状が固定されているため、雨水貯留浸透槽の形状に対して柔軟に対応できないという問題もある。   In addition, when transporting the above-mentioned conventional container-like members and fillers, since they contain a large space for storing rainwater and are bulky, there is a problem that the transportation cost is high for the transport amount. is there. Moreover, since these container-like members and fillers have fixed shapes, there is also a problem that they cannot be flexibly adapted to the shape of the rainwater storage and penetration tank.

そこで、本発明の目的は、上記従来技術の有する問題点に鑑みて、組み立てた場合に、大きい開口部を確保できて保守点検が容易であり、しかも個々の構成部材から組立を容易にして、現地での組立を可能にすることにより輸送コストを低減でき、かつ雨水貯留浸透槽の形状に対して柔軟に対応可能な雨水貯留構造用部材とこれを用いた雨水貯留構造物を提供することにある。   Therefore, in view of the above-mentioned problems of the prior art, the object of the present invention is to ensure a large opening, facilitate maintenance and inspection, and facilitate assembly from individual components. To provide a rainwater storage structure member and a rainwater storage structure using the rainwater storage structure member that can reduce the transportation cost by enabling on-site assembly and can flexibly cope with the shape of the rainwater storage and penetration tank. is there.

上記課題は、請求項記載の発明により達成される。すなわち、本発明に係る雨水貯留構造用部材の特徴構成は、所定長さを有する複数の樹脂製パイプ状縦部材と、これらパイプ状縦部材と共に三次元構造体を組み立てる横部材と、前記パイプ状縦部材に前記横部材を接続するための接続治具とを有し、これらパイプ状縦部材と横部材とを、前記接続治具を介して三次元構造体に組み立てることにより、内部に空間を形成可能にすることにある。   The above object can be achieved by the invention described in the claims. That is, the characteristic configuration of the rainwater storage structure member according to the present invention includes a plurality of resin pipe-like longitudinal members having a predetermined length, a transverse member for assembling a three-dimensional structure with these pipe-like longitudinal members, and the pipe-like shape. A connecting jig for connecting the horizontal member to the vertical member, and assembling the pipe-shaped vertical member and the horizontal member into a three-dimensional structure via the connecting jig, thereby creating a space inside. It is to make it possible to form.

この構成によれば、樹脂製パイプ状縦部材と横部材と接続治具との組み合わせで構成されているため、パイプ状縦部材と横部材の長さを選択するだけで、保守点検可能な所定広さの開口部を容易に形成することができ、しかも、施工現場に輸送する際には、樹脂製パイプ状縦部材と横部材と接続治具とを、組み立てた状態にすることなく、夫々の部材として輸送することになるので、従来技術のように、少なくない空間を有する容器状部材や充填材として輸送するものではないため、輸送時の嵩が小さくて済み、効率の良い輸送ができることになり、輸送コストを大幅に低減できる。のみならず、樹脂製パイプ状縦部材および横部材の長さ、径など形状を変更することにより、雨水貯留浸透槽の形状に応じて柔軟に対応でき、従来技術に比べて設計の自由度が格段に向上する。   According to this configuration, since it is configured by a combination of a plastic pipe-like vertical member, a horizontal member, and a connecting jig, a maintenance inspection can be performed only by selecting the length of the pipe-like vertical member and the horizontal member. A wide opening can be easily formed, and when transporting to the construction site, the plastic pipe-like vertical member, the transverse member and the connecting jig are not assembled, respectively. Because it is not transported as a container-like member or filler having a small space as in the prior art, the bulk during transportation is small and efficient transportation is possible. Therefore, the transportation cost can be greatly reduced. Not only can the length and diameter of the plastic pipe-like vertical and horizontal members be changed, but it can be flexibly adapted to the shape of the rainwater storage and infiltration tank. Greatly improved.

その結果、組み立てた場合に、大きい開口部を確保できて保守点検が容易であり、しかも個々の構成部材から組立を容易にして、現地での組立を可能にすることにより輸送コストを低減でき、かつ雨水貯留浸透槽の形状に対して柔軟に対応可能な雨水貯留構造用部材を提供することができた。   As a result, when assembled, a large opening can be secured and maintenance inspection is easy.In addition, the assembly cost can be reduced by facilitating the assembly from individual components and enabling on-site assembly. And the member for rain water storage structures which can respond flexibly with respect to the shape of a rain water storage penetration tank was able to be provided.

前記接続治具は、前記パイプ状縦部材に嵌合して装着されると共に、前記横部材とは係止して連結されることが好ましい。   It is preferable that the connecting jig is fitted and attached to the pipe-shaped vertical member and is engaged and connected to the horizontal member.

この構成によれば、接続治具を介してパイプ状縦部材と横部材とを接続するので、別にボルトとナットのような固着具を用意して締め付ける必要がなく、接続作業が容易であり、現地での三次元構造体への組立作業を一層効率良く行うことができる。   According to this configuration, since the pipe-shaped vertical member and the horizontal member are connected via the connection jig, it is not necessary to prepare and tighten a fixing tool such as a bolt and a nut, and the connection work is easy. The assembly work to the three-dimensional structure on site can be performed more efficiently.

前記三次元構造体は、少なくとも１０８ｋＮ／ｍ2以上の圧縮強度を有することが好ましい。 The three-dimensional structure preferably has a compressive strength of at least 108 kN / m 2 or more.

この構成によれば、最上部に覆土２ｍ程度を施工したとしても、土圧の３倍以上となる十分な強度を有する。   According to this configuration, even if about 2 m of covering soil is applied to the uppermost portion, the structure has a sufficient strength that is three times or more the earth pressure.

また、本発明に係る雨水貯留構造物の特徴構成は、地面凹部に敷設された遮水材と、この遮水材の上面側に配置された請求項１〜３のいずれか１項に記載の雨水貯留構造用部材から組み立てられた三次元構造体と、この三次元構造体の上面側に配置された被覆層を有することにある。   Moreover, the characteristic structure of the rainwater storage structure which concerns on this invention is the water shielding material laid in the ground recessed part, and the any one of Claims 1-3 arrange | positioned at the upper surface side of this water shielding material. The object is to have a three-dimensional structure assembled from the rainwater storage structural member and a coating layer disposed on the upper surface side of the three-dimensional structure.

この構成によれば、組み立てた場合に、大きい開口部を確保できて保守点検が容易であり、しかも個々の構成部材から組立を容易にして、現地での組立を可能にすることにより輸送コストを低減でき、かつ雨水貯留浸透槽の形状に対して柔軟に対応可能な雨水貯留構造用部材を用いた雨水貯留構造物を提供することができる。   According to this configuration, when assembled, a large opening can be secured, maintenance and inspection are easy, and the assembly cost can be reduced by facilitating the assembly from individual components and enabling on-site assembly. A rainwater storage structure using a member for rainwater storage structure that can be reduced and can flexibly cope with the shape of the rainwater storage and penetration tank can be provided.

That is, FIG. 1A shows a planar structure of the connecting jig 1, and FIG. 1B shows an II cross-sectional structure. 2A shows the left side structure of the transverse member 2, FIG. 2B shows the bottom structure, and FIG. 2C shows the II-II cross-sectional structure. FIG. 3A shows the front structure of the pipe-like vertical member 3, and FIG. 3B shows the III-III cross-sectional structure. FIGS. 4 and 5 assemble a jungle gym-like rainwater storage structure assembly A, which is a three-dimensional structure, by combining the connecting jig 1, the transverse member 2, and the pipe-like longitudinal member 3 shown in FIGS. FIG. 4 shows the partial front structure, and FIG. 5 shows the partial planar structure.

接続治具１は樹脂製であり、図１に示すように、縦部材３に外嵌可能な筒状部１ａと、外周面の４箇所から突出して横部材２の端部と係合して両者を接続する突出部１ｂを有していて、突出部１ｂには、後述する横部材２の端部突起２ａを受け入れて係合する貫通孔１ｃが４箇形成されている。更に、筒状部１ａ内部にも、やや小径の貫通孔１ｄが形成されて重量軽減が図られていると共に、雨水を下方に移動させて貯留させるようになっている。   As shown in FIG. 1, the connecting jig 1 is made of resin. As shown in FIG. The projecting portion 1b is connected to the projecting portion 1b. The projecting portion 1b is formed with four through holes 1c that receive and engage end projections 2a of the lateral member 2 described later. Further, a slightly smaller diameter through hole 1d is formed inside the cylindrical portion 1a to reduce weight, and rainwater is moved downward to be stored.

横部材２は樹脂製であり、図２に示すように、接続治具１の貫通孔１ｃに挿入されて係合する端部突起２ａを両端部に下向きに形成していると共に、長手方向の途中２箇所に所定間隔を空けて補強用のリブ２ｂが設けられている。もっとも、補強用のリブ２ｂの数、位置、形状などは種々に変更可能である。   The horizontal member 2 is made of resin, and as shown in FIG. 2, end projections 2a that are inserted into and engaged with the through holes 1c of the connecting jig 1 are formed downward at both ends, and the longitudinal members 2 Reinforcing ribs 2b are provided at predetermined intervals in two places. However, the number, position, shape, and the like of the reinforcing rib 2b can be variously changed.

パイプ状縦部材３は樹脂製からなり、図３（イ）、（ロ）に示すように、所定長さを有する円筒形をしており、接続治具１の筒状部１ａに内嵌可能になっている。   The pipe-like vertical member 3 is made of resin and has a cylindrical shape having a predetermined length as shown in FIGS. 3A and 3B, and can be fitted into the cylindrical portion 1 a of the connecting jig 1. It has become.

そして、立設された各パイプ状縦部材３の上端に接続治具１を嵌合して装着しておき、２本のパイプ状縦部材３に装着された各接続治具１どうしの内、互いに隣接する２個の接続治具１の貫通孔１ｃの夫々に、横部材２の端部突起２ａを挿入させて係合することにより、パイプ状縦部材３と横部材２とを接続し、これを繰り返えして、図４，５にその一部を示すように、ジャングルジム状に三次元構造体を構成する雨水貯留構造用組立物Ａを形成する。   Then, the connection jig 1 is fitted and attached to the upper end of each of the pipe-like vertical members 3, and the connection jigs 1 attached to the two pipe-like vertical members 3 are connected to each other. The pipe-shaped vertical member 3 and the horizontal member 2 are connected by inserting and engaging the end protrusions 2a of the horizontal member 2 into the through holes 1c of the two connecting jigs 1 adjacent to each other, By repeating this, as shown in FIGS. 4 and 5, a rainwater storage structure assembly A that forms a three-dimensional structure in a jungle gym shape is formed.

つぎに、本実施形態に係る雨水貯留構造用組立部材を組み立てた雨水貯留構造用組立物Ａを、雨水貯留構造物に用いる施工例について説明する。   Below, the construction example which uses the assembly A for rainwater storage structures which assembled the assembly member for rainwater storage structures which concerns on this embodiment for a rainwater storage structure is demonstrated.

図６に示すように、地面に１〜５ｍ程度の凹部（ピット）を掘削・形成すると共に、ピット周囲に側溝７を形成し、ピットの底面に砕石、砂などを敷設・施工し平準化して基礎Ｂを形成する。その表面に遮水材である遮水シート４を敷設した後、樹脂製の各パイプ状縦部材３と接続治具２とから、図４，５に示すように、ピットの内容積に応じジャングルジム状の雨水貯留構造用組立物Ａを構成する。ピットの内容積が大きい場合には、ピット内で雨水貯留構造用組立物Ａを組み立ててもよいし、雨水貯留構造用組立物Ａをピット外で組み立てた後、ピット内に挿入するようにしてもよい。このようにして組み立てた雨水貯留構造用組立物Ａは、樹脂製あるいは金属製などのベルトで締結・固定されることが好ましい。更に、側面外周部には、角形のパネルをパイプ間に嵌め込んで側面外周部での平坦性を確保すると共に、強度を高めるようにしてもよい。   As shown in FIG. 6, a recess (pit) of about 1 to 5 m is excavated and formed on the ground, a side groove 7 is formed around the pit, and crushed stones and sand are laid and constructed on the bottom surface of the pit and leveled. Form foundation B. After the water-impervious sheet 4 as a water-impervious material is laid on the surface, the pipe-shaped vertical member 3 and the connecting jig 2 are used to jungle according to the internal volume of the pit as shown in FIGS. A gym-shaped assembly for rainwater storage structure A is formed. When the internal volume of the pit is large, the rainwater storage structure assembly A may be assembled in the pit, or after the rainwater storage structure assembly A is assembled outside the pit, it is inserted into the pit. Also good. The rainwater storage structure assembly A thus assembled is preferably fastened and fixed with a belt made of resin or metal. Further, a square panel may be fitted between the pipes on the outer peripheral portion of the side surface to ensure flatness at the outer peripheral portion of the side surface and increase the strength.

ついで、雨水貯留構造用組立物Ａの側面部Ｃには、必要に応じて埋め戻しを行うと共に、側溝７よりピット内に雨水を流し込み可能に連通する配管８を敷設し、更に、上面に遮水シート５を被覆し、その上から０．５〜１ｍ程度の覆土６を施す。これら、上面の遮水シート５、覆土６は、被覆層を形する。もっとも、雨水貯留構造用組立物Ａ上面に遮水シート５を被覆する代わりに、透水性シートを被覆して雨水を浸透させるようにしてもよい。側溝７は、その底部に泥溜９が形成されるように、底部が幾分深くなっている。   Next, the side surface C of the rainwater storage structure assembly A is backfilled as necessary, and a piping 8 is laid so as to allow rainwater to flow into the pits from the side grooves 7 and is further shielded on the upper surface. The water sheet 5 is covered, and a covering soil 6 of about 0.5 to 1 m is applied from above. These water-impervious sheet 5 and covering soil 6 on the upper surface form a covering layer. But you may make it infiltrate rainwater by coat | covering a water-permeable sheet | seat instead of coat | covering the water-impervious sheet 5 on the assembly A for rainwater storage structures. The side groove 7 is somewhat deep at the bottom so that a mud pool 9 is formed at the bottom.

三次元構造体である雨水貯留構造用組立物Ａは、少なくとも１０８ｋＮ／ｍ2以上の圧縮強度を有することが好ましい。このようにすれば、最上部に覆土２ｍ程度（負荷：約３６ｋＮ／ｍ2 ）を施工したとしても、土圧の３倍以上となる十分な強度を有する。具体的には、長さ約５０ｃｍのパイプ状部材を使用する場合、４本／ｍ2 で少なくとも２７ｋＮ／本の圧縮強度を有するものを使用し、長さ約４０ｃｍのパイプ状部材を用いる場合には、６．２５本／ｍ2 で少なくとも圧縮強度約１７．２８ｋＮ／本を有するパイプ状部材を用いる。 The rainwater storage structure assembly A, which is a three-dimensional structure, preferably has a compressive strength of at least 108 kN / m 2 or more. In this way, even if covering soil of about 2 m (load: about 36 kN / m 2 ) is applied to the uppermost part, it has sufficient strength to be at least three times the earth pressure. Specifically, when a pipe-like member having a length of about 50 cm is used, a pipe-like member having a compressive strength of at least 27 kN / piece at 4 / m 2 is used, and a pipe-like member having a length of about 40 cm is used. Uses a pipe-shaped member having a compression strength of at least about 17.28 kN / line at 6.25 lines / m 2 .

このようにすることにより、一旦雨水を貯留して、庭園などへの散水、洗浄水、非常用水など各種用途に利用したり、大量の雨水を徐々に放流できるような調整機能を備えさせたりすることができる。しかも、コンクリートで構成する場合に比べて、養生期間などが不要であることから、雨水貯留構造物の構築速度を格段に早くすることができる。   In this way, rainwater is temporarily stored and used for various purposes such as watering gardens, washing water, emergency water, etc., and an adjustment function that can gradually discharge a large amount of rainwater is provided. be able to. And since the curing period etc. are unnecessary compared with the case where it comprises with concrete, the construction speed of a rainwater storage structure can be made markedly faster.

外径約６０ｍｍ、肉厚約５．５ｍｍ、長さ約５０ｍｍのポリエチレン製パイプ（積水化学工業製。商品名：エスロンハイパーＰＥ）を用いて、図１に示す接続治具を用いて、図４，５にその一部を示すような、高さ約３ｍ、縦横約３ｍの雨水貯留構造組立物Ａを形成し、深さ約５ｍの所定内容積を有するピット内に配置し、雨水貯留構造物を構築した。このポリエチレン製パイプは、長さ方向の圧縮強度約２７ｋＮ／本を有しており、１ｍ2当たり４本を使用すると、圧縮強度１０８ｋＮ／ｍ2が得られ、覆土を２ｍ（負荷：約３６ｋＮ／ｍ2）とした場合でも、約３倍強の圧縮強度が得られるので、十分に実用的であることがわかる。 Using a polyethylene pipe (made by Sekisui Chemical Co., Ltd., trade name: ESLON Hyper PE) having an outer diameter of about 60 mm, a wall thickness of about 5.5 mm, and a length of about 50 mm, the connection jig shown in FIG. , 5, a rainwater storage structure assembly A having a height of about 3 m and a length and width of about 3 m, as shown in a part thereof, is disposed in a pit having a predetermined internal volume of about 5 m in depth. Built. This polyethylene pipe has a compressive strength of about 27 kN / piece in the length direction. When four pipes are used per 1 m 2 , a compressive strength of 108 kN / m 2 is obtained, and the covering soil is 2 m (load: about 36 kN / piece). Even in the case of m 2 ), it can be seen that the compression strength of about 3 times is obtained, which is sufficiently practical.

実際、１ｍ×１ｍ×１ｍの大きさで雨水貯留構造物を構築し、その上から２ｍの覆土に相当する重錘を載置して１年以上経過したが、使用上問題となる変形その他のトラブルは一切生じなかった。
〔別実施の形態〕
（１）上記実施形態の場合、樹脂製パイプ状部材の構成材料としてポリエチレン製を例示したが、これに限定されるものではなく、ポリプロピレン、ポリ塩化ビニル、ＰＥＴ（ポリエチレンテレフタレート）等を使用してもよいし、必要な強度が得られれば、各種の熱可塑性樹脂を使用することができる。
（２）上記実施形態では、パイプ状部材３を接続治具１の筒状部１ａに内嵌可能に構成した例を示したが、接続治具１の筒状部１ａの外径を小さくして、パイプ状部材３に内嵌させるようにしてもよい。
（３）上記実施形態では、横部材２の端部突起２ａを円筒状にし、この端部突起２ａを挿入して係合する接続治具１の貫通孔１ｃを円形とした例を示したが、これに代えて、横部材２の端部突起２ａを角状とし、接続治具１の貫通孔１ｃもこれを挿入可能に角形にしてもよい。このようにすると、横部材２と接続治具１の位置、すなわち、横部材２とパイプ状部材３の位置が固定されるようになって両者が係止され、組立時に扱い易くなると共に外力による変形に抵抗できて好ましい。
（４）パイプ状部材、横部材、接続治具とは、同じ材質の樹脂製としたが、異なる材質の樹脂製であってもよい。
（５）樹脂製パイプ状部材、横部材、接続治具の構成材料に、粉体状の炭酸カルシウム（炭カル）等を混入させるようにしてもよい。このようにすると、構成材料の比重を大きくすることができ、雨水を貯留する際に生じる浮力に抗することができ、浮力対策として特別な施工が不必要となり、小さいスペースでもより大きい貯水量が確保できて好ましい。具体的には、１３％程度の炭カルを樹脂に混入させることにより、比重を１．０以上にすることができる。 In fact, a rainwater storage structure was constructed with a size of 1m x 1m x 1m, and a weight equivalent to 2m of cover soil was placed on it for more than a year. No trouble occurred.
