Description
【０００１】[0001]
この考案は、雨水貯留浸透施設の構造に係わり、更に詳しくは雨水の貯留容量 が大きく，しかも施工が簡単な雨水貯留浸透施設の構造に関するものである。 The present invention relates to the structure of a rainwater storage and infiltration facility, and more specifically to the structure of a rainwater storage and infiltration facility that has a large rainwater storage capacity and is easy to construct.
【０００２】[0002]
近年、都市開発が進み、自然地盤の表面が締固められ、また道路や建物等で表 面が覆われてくると、降雨時に地中に浸透する雨水の量は非常に少なくなって、 大部分は短時間に河川に流出するようになり、河川の氾濫による浸水災害が多発 して来ているのが現状である。このような問題の対処として、河川改修，調整池 方式の他、地盤の持つ自然浸透能力を有効に利用して雨水を積極的に地下浸透処 理する方法が多数実施されている。 In recent years, as urban development progresses and the surface of natural ground is compacted and the surface is covered with roads and buildings, the amount of rainwater that penetrates into the ground during rainfall becomes extremely small, and Is now flowing into the river in a short period of time, and the current situation is that flooding disasters are frequently occurring due to flooding of the river. In order to deal with such problems, in addition to river improvement and regulation pond methods, many methods of actively utilizing the natural infiltration capacity of the ground to actively infiltrate rainwater underground have been implemented.
【０００３】 ところで、上記の地下浸透処理構造は、地盤を掘削し、掘削孔の内壁面に雨水 を貯留する場合には遮水シートを敷設し、浸透の場合には透水シートを張り付け 、内部に砕石や砂を充填すると共に、雨水流入用の透水パイプや排水パイプを配 管し、その上部を土砂等で埋め戻した構成になっている。By the way, in the above-mentioned underground infiltration treatment structure, when excavating the ground and storing rainwater on the inner wall surface of the excavation hole, a water barrier sheet is laid, and in the case of infiltration, a water permeable sheet is attached, and In addition to filling with crushed stone and sand, a permeate pipe for draining rainwater and a drainage pipe are installed, and the upper part is backfilled with earth and sand.
【０００４】[0004]
然しながら、上記のような地下浸透処理構造は、砕石の空隙率が４０％程度と 小さく、貯留効率が極めて悪いと言う問題があり、掘削や埋め戻す等の土工事が 多く、施工に多くの手間と時間を要すると言う問題があった。 この考案は、かかる従来の課題に着目して案出されたもので、雨水の貯留容量 が大きく，しかも構成及び施工が簡単で、貯留効率を高めることが出来る雨水貯 留浸透施設の構造を提供することを目的とするものである。 However, the above-mentioned underground infiltration treatment structure has a problem that the porosity of crushed stone is as small as about 40% and the storage efficiency is extremely poor, and there is a lot of earthwork such as excavation and backfilling, and much labor is required for construction. There was a problem that it took time. The present invention was devised by focusing on such conventional problems, and provides a structure of a rainwater storage / infiltration facility that has a large rainwater storage capacity, is simple in configuration and construction, and can enhance storage efficiency. The purpose is to do.
【０００５】[0005]
この考案は上記目的を達成するため、側面に貫通孔を備えた複数本の有孔パイ プを開口部を上下にして掘削穴内に配置し、前記有孔パイプの上部開口部上に透 水性支持板を配置し、この透水性支持板の上部にブロック材を配置し、ブロック 材により廻りが覆われた取水部材、または取水部材及び排水部材を設け、前記有 孔パイプの下部開口部及び側部周囲に、透水シートまたは遮水シートを設けたこ とを要旨とするものである。 In order to achieve the above-mentioned object, the present invention arranges a plurality of perforated pipes having through holes on the side surfaces in an excavation hole with the openings above and below, and provides a water-permeable support on the upper opening of the perforated pipe. A plate is arranged, a block material is arranged above this water-permeable support plate, and a water intake member whose circumference is covered by the block material, or a water intake member and a drain member are provided, and the lower opening and side parts of the perforated pipe are provided. The main point is to provide a water-permeable sheet or a water-blocking sheet around it.
【０００６】[0006]
この考案は上記のように構成され、側面に貫通孔を備えた複数本の有孔パイプ を地盤掘削孔内に埋設するので、パイプによる空隙率が大きく、貯留容量も大き くすることが出来、従って、掘削土量も少ない上、掘削穴内に容易に配置出来る ので施工作業を効率良く行うことが出来、また砕石充填に比べて施工作業を簡単 に行うことが出来るものである。 This invention is configured as described above, and since a plurality of perforated pipes having through holes on the side surface are embedded in the ground excavation hole, the porosity of the pipes can be large and the storage capacity can be large. Therefore, the amount of excavated soil is small, and since it can be easily placed in the excavation hole, the construction work can be performed efficiently, and the construction work can be performed more easily than crushed stone filling.
