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部材と、これらパイプ状部材を連結可能にする連結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 rainwater storage structure, and more specifically, includes a plurality of resin pipe-shaped members having a predetermined length, and a connecting member that enables connection of these pipe-shaped members. The present invention relates to a rainwater storage structure member 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部材と、所定長さを有し前記パイプ状部材どうしを連結して三次元構造体に組み立て可能な連結部材とを備え、前記パイプ状部材と連結部材とから形成される三次元構造体の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 is a three-dimensional structure formed by connecting a plurality of resin pipe-shaped members having a predetermined length and the pipe-shaped members having a predetermined length. And a connecting member that can be assembled. A space can be formed inside a three-dimensional structure formed by the pipe-shaped member and the connecting member.

この構成によれば、樹脂製パイプ状部材と連結部材とで三次元構造体を組み立てるため、パイプ状部材と連結部材の長さを選択するだけで、容易に所定の広さの開口部を形成することができ、しかも、施工現場に輸送する際には、樹脂製パイプ状部材と連結部材とを個別に、組立前の状態で輸送することになるので、従来技術のように、少なくない空間と体積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、輸送時の嵩が著しく小さくて済み、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、樹脂製パイプ状部材と連結部材の長さ、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 the three-dimensional structure is assembled with the resin pipe-like member and the connecting member, an opening having a predetermined width can be easily formed simply by selecting the length of the pipe-like member and the connecting member. In addition, when transporting to the construction site, the resin pipe-like member and the connecting member are transported individually in the state before assembly, so there is not a lot of space as in the prior art. Therefore, the bulk at the time of transportation can be remarkably small, and efficient transportation can be achieved, so that the transportation cost can be greatly reduced. In addition, by changing the length and diameter of the resin pipe-like member and connecting member, it is possible to flexibly respond to the shape of the rainwater storage and infiltration tank, and the design flexibility is significantly higher than that of the conventional technology. To improve.

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.

前記連結部材は、少なくともその端部において、前記パイプ状部材と略直角方向に嵌合して連結可能になっていることが好ましい。   It is preferable that at least an end portion of the connecting member can be connected to the pipe-like member by fitting in a substantially right angle direction.

この構成によれば、パイプ状部材に連結部材を嵌合させてパイプ状部材どうしを連結し、パイプと接続部材とを互いに直角方向になるように接続することを繰り返すことにより、現地において容易に三次元構造体に組み立てることができる。尚、１のパイプ状部材に２〜４の連結部材を連結する場合の高さ調節には、所定高さのスペーサーを使用する等により、容易に行うことができる。   According to this configuration, the connecting member is fitted to the pipe-like member, the pipe-like members are connected to each other, and the pipe and the connecting member are connected so as to be perpendicular to each other. Can be assembled into a three-dimensional structure. It should be noted that the height adjustment when connecting 2 to 4 connecting members to one pipe-shaped member can be easily performed by using a spacer having a predetermined height.

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 rainwater of any one of Claims 1-3 arrange | positioned at the upper surface side of the water shielding material laid in the ground recessed part, and this water shielding material. The object is to have a three-dimensional structure assembled from a storage structure 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.

本発明の実施形態を、図面を参照して詳細に説明する。図１、２は、本実施形態に係る雨水貯留構造用組立部材として使用するパイプ状部材１と連結部材２を示す。すなわち、図１（イ）は、パイプ状部材１の正面断面構造を示し、（ロ）は、ロ−ロ断面構造を示す。図２（イ）は連結部材２の平面構造、（ロ）は正面断面構造、（ハ）はハ−ハ断面構造を示す。図３、４は、図１、２に示すパイプ状部材１と連結部材２とを組み合わせて、三次元構造体であるジャングルジム状の雨水貯留構造用組立物Ａを組み立てる手順を示す。   Embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 show a pipe-like member 1 and a connecting member 2 used as an assembly member for a rainwater storage structure according to this embodiment. That is, FIG. 1 (A) shows a front cross-sectional structure of the pipe-like member 1, and (B) shows a roll cross-sectional structure. 2A shows a planar structure of the connecting member 2, FIG. 2B shows a front sectional structure, and FIG. 2C shows a ha-ha sectional structure. 3 and 4 show a procedure for assembling the jungle gym-shaped rainwater storage structure assembly A, which is a three-dimensional structure, by combining the pipe-like member 1 and the connecting member 2 shown in FIGS.

パイプ状部材1は樹脂製からなり、図１に示すように、円筒部１ａとその下部にやや拡径された拡径部１ｂとを有して略円筒形をしている。そして、拡径部１ｂの内径は、パイプ状部材1が互いに高さ方向に連結可能に、円筒部１ａの外径よりやや大きくなっていて、円筒部１ａに外嵌できるようになっている。連結部材２は、パイプ状部材1と同様に樹脂製からなり、図２に示すように、両端部に形成されている円筒形の接続端２ａとこれら接続端２ａどうしを接続する軸部２ｂからなっていると共に、軸部２ｂは図２（ハ）に示すように、断面略＋形をしている。   The pipe-shaped member 1 is made of resin, and as shown in FIG. 1, has a cylindrical portion 1a and a diameter-expanded portion 1b that is slightly enlarged at the lower portion thereof, and has a substantially cylindrical shape. The inner diameter of the enlarged diameter portion 1b is slightly larger than the outer diameter of the cylindrical portion 1a so that the pipe-like members 1 can be connected to each other in the height direction, and can be fitted on the cylindrical portion 1a. The connecting member 2 is made of resin like the pipe-shaped member 1, and as shown in FIG. 2, a cylindrical connection end 2a formed at both ends and a shaft portion 2b connecting the connection ends 2a. As shown in FIG. 2C, the shaft portion 2b has a substantially cross-sectional shape.

パイプ状部材１と連結部材２とは、図３に示すように、パイプ状部材1の複数本を予め立設しておき、これらパイプ状部材1に接続部材２の接続端２ａを嵌合させて、ジャングルジム状の雨水貯留構造用組立物Ａを組み立てることができる。接続部材２の円筒形接続端２ａは、パイプ状部材1の円筒部１ａに外嵌されると共に、拡径部１ｂの上部で係止され、この拡径部１ｂの外径と接続部材２の円筒形接続端２ａの外径とが略同寸になっている。このようにすると、両部材を組み立てた際に、雨水貯留構造用組立物Ａにおける縦方向の凹凸が少なくなり、この部分での土砂その他が積層されるのを防止できて好ましい。もっとも、パイプ状部材1と接続部材2との連結は、パイプ状部材１と連結部材２とを連結した後、ピット内に立設するようにしてもよい。   As shown in FIG. 3, the pipe-shaped member 1 and the connecting member 2 have a plurality of pipe-shaped members 1 standing in advance, and the connection ends 2 a of the connection members 2 are fitted to these pipe-shaped members 1. Thus, the jungle gym-shaped rainwater storage structure assembly A can be assembled. The cylindrical connecting end 2a of the connecting member 2 is fitted on the cylindrical portion 1a of the pipe-like member 1 and is locked at the upper portion of the enlarged diameter portion 1b. The outer diameter of the enlarged diameter portion 1b and the connecting member 2 The outer diameter of the cylindrical connection end 2a is substantially the same. If it does in this way, when both members are assembled, the unevenness | corrugation of the vertical direction in the assembly A for rainwater storage structures will decrease, and it can prevent that the earth and sand etc. in this part are laminated | stacked. However, the pipe-shaped member 1 and the connecting member 2 may be connected in a standing manner in the pit after the pipe-shaped member 1 and the connecting member 2 are connected.

更に、２本のパイプ状部材１に１本の連結部材２を連結した後、これらを互いに連結するため、図４に示すように、更に連結部材２をパイプ状部材１に嵌合して連結する。その場合、新たな連結部材２の接続端２ａを既存の連結部材２の接続端２ａの上部に重ねることになるが、複数の連結を繰り返すうちに、高さに段差を生じることがあり、その場合には、所定高さを有し、パイプ状部材1の円筒部１ａに外嵌可能な内径を有する円筒形のスペーサー３を用いて、段差を調整することができる。また、高さ方向にパイプ状部材１どうしを連結する場合にも、適度な長さのスペーサー３を用いて行うことができる。このような動作を繰り返すことにより、ジャングルジム状の雨水貯留構造用組立物Ａを構築することができる。   Further, after connecting one connecting member 2 to two pipe-like members 1 and connecting them together, the connecting member 2 is further fitted and connected to the pipe-like member 1 as shown in FIG. To do. In that case, the connection end 2a of the new connection member 2 is overlapped on the upper part of the connection end 2a of the existing connection member 2, but a step may be generated in height while repeating a plurality of connections. In this case, the step can be adjusted by using a cylindrical spacer 3 having a predetermined height and having an inner diameter that can be fitted onto the cylindrical portion 1a of the pipe-shaped member 1. Moreover, when connecting the pipe-shaped members 1 in the height direction, the spacer 3 having an appropriate length can be used. By repeating such an operation, the jungle gym-like rainwater storage structure assembly A can be constructed.

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を説明する。   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５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。その表面に遮水シート４を敷設した後、樹脂製のパイプ状部材1と接続部材２とから、図１〜４に示す手順で、ピットの内容積に応じた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. 5, a recess (pit) of about 1 to 5 m is excavated and formed in the ground, and a side groove 7 is formed around the pit, and crushed stone and sand are laid and constructed on the bottom surface of the pit and leveled. Form foundation B. After laying the water-impervious sheet 4 on the surface, the jungle gym-shaped rainwater storage structure corresponding to the internal volume of the pit is obtained from the resin pipe-like member 1 and the connecting member 2 according to the procedure shown in FIGS. The assembly A is configured. 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.

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、ついで０．５〜１ｍ程度の覆土６をする。ここに、遮水シート５と覆土６とは被覆層を構成する。もっとも、雨水貯留構造用組立物上面に遮水シート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。   The side surface C of the rainwater storage structure assembly A is backfilled as necessary, and a pipe 8 is laid through the side groove 7 so as to allow rainwater to flow into the pit. 5 and then covering soil 6 of about 0.5 to 1 m. Here, the water-impervious sheet 5 and the covering soil 6 constitute a covering layer. Of course, instead of covering the rainwater storage structure assembly on the upper surface with the water shielding sheet 5, the rainwater may be infiltrated with a water permeable sheet. 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５０ｃｍ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１〜４に示す手順により、高さ約３ｍ、縦横約３ｍの雨水貯留構造組立物を形成し、深さ約５ｍの所定内容積を有するピット内に配置し、図５に示すような、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 cm, the height is about 3 m. A rainwater storage structure assembly having a length and width of about 3 m was formed and placed in a pit having a predetermined internal volume of about 5 m in depth to construct a rainwater storage structure as shown in FIG. 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）パイプ状部材と接続部材とは、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。
（３）パイプ状部材、接続部材の構成材料に、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.
[Another embodiment]
(1) In the case of the said embodiment, although the product made from polyethylene was illustrated as a constituent material of a resin-made pipe-shaped member, it is not limited to this, Polypropylene, polyvinyl chloride, PET (polyethylene terephthalate) etc. are used. Alternatively, various thermoplastic resins can be used as long as the required strength is obtained.
(2) The pipe member and the connection member are made of the same resin material, but may be made of different resin materials.
(3) Powdery calcium carbonate (charcoal) or the like may be mixed in the constituent materials of the pipe-shaped member and the connecting member. In this way, the specific gravity of the constituent materials can be increased, the buoyancy that occurs when rainwater is stored can be resisted, special construction is not required as a buoyancy measure, and a larger amount of water can be stored even in a small space. It is preferable because it can be secured. Specifically, the specific gravity can be made 1.0 or more by mixing about 13% charcoal cal in the resin.
