Abstract

<P>PROBLEM TO BE SOLVED: To provide a culvert water storage infiltration tank capable of coping with a flood caused by concentrated heavy rain in a city and intense heat in summer due to the heat island phenomenon, reducing cost and term of construction, and ensuring safety. <P>SOLUTION: The flood in a city is caused because the dropped rainwater does not permeate the ground and enters a ditch, a drainage channel, and a river in a concentrated manner all at once. Therefore, the water storage tank is installed to store the dropped rainwater once and let it infiltrate the ground. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

この発明は雨水をただちに川に放水するのではなく地下に貯水し、浸透させる貯水槽に関するものである。The present invention relates to a water storage tank in which rainwater is not immediately discharged into a river but stored underground and permeated.

従来は雨水をどぶや排水路などで川に放水するだけであった。In the past, rainwater was only discharged to the river through a drain or drainage.

これは次のような欠点があった。
（イ）従来の排水路は雨水をただちに川に放水するだけなので、都市型の集中豪雨においてはたびたび洪水をひきおこしており、地下鉄や地下街への被害も現実みをおびている。
（ロ）都市部においては路面がほとんどアスファルトやコンクリートで覆われており、露出した地面が少ないため、雨水が地中にしみこみにくくなっている。本発明はこれを解決する手段として有効である。This has the following drawbacks.
(B) The conventional drainage channel only discharges rainwater immediately to the river, so floods frequently occur in urban torrential rains, and damage to subways and underground shopping centers is also real.
(B) In urban areas, the road surface is almost covered with asphalt and concrete, and there is little exposed ground, making it difficult for rainwater to penetrate into the ground. The present invention is effective as a means for solving this.

国や都道府県市町村が買収する必要がない、都市全体の面積のおよそ３０％強を占めるといわれる道路の地下部分や公共のグラウンドや公園などだけでも、雨水を浸透させる貯水槽をもうけると、費用が安あがりな洪水対策になりえる。It is not necessary to acquire a national or prefectural municipality, and it is costly to make a water tank that can infiltrate rainwater even in the underground part of roads, public grounds and parks that are said to occupy about 30% of the total area of the city. Can be a safe flood countermeasure.

（イ）排水路化した都市型の河川に雨水を集中させないことで洪水をふせぐ。
（ロ）荒川を例にとると、荒川流域には都市部が発達しており、降った雨水のほとんどは地下に浸透することなく河川に流れ込んでいると思われるので、流域一帯の都市が貯水槽をもうけて、荒川への直接の流入量をへらせば台風などによる洪水対策になると思われる。
（ハ）地下水のくみ上げにより地盤沈下が問題になっている所では、その対策として暗染貯水槽をもうけて、暗染排水の技術を真逆に利用し水を地下深部に浸透させることである程度の解決策になると思われる。
（ニ）東京などの夏においては、地中に水分をたっぷり含ませることにより、草花樹木の立ち枯れを防ぐことができ、さらに緑地を増やすことにより、ヒートアイランド現象の抑制につながる効果が期待できる。
（ホ）河川の流量については、土中よりゆっくりと浸み出してきた水により、ふだんからの流量が増え、清流化が期待できる。
（ヘ）また想定降水量により暗染貯水槽の大小の設計が可能なこと。(B) Floods are prevented by not concentrating rainwater on urban rivers that have become drainage channels.
(B) Taking Arakawa as an example, urban areas have developed in the Arakawa basin, and most of the rainwater that falls has flowed into the river without penetrating underground. If a tank is created and the amount of direct inflow into the Arakawa River is reduced, it will be a countermeasure against floods caused by typhoons.
(C) In places where ground subsidence has become a problem due to groundwater pumping, as a countermeasure, a dark-dyed water storage tank is established, and by using the technology of dark-dyed drainage to reverse the water, It seems to be a solution.
(D) In summer, such as Tokyo, it is possible to prevent the withering of flowering trees by adding a lot of moisture to the ground, and by increasing the green space, an effect that leads to suppression of the heat island phenomenon can be expected.
(E) Regarding the river flow rate, the water that has slowly leached out of the soil will increase the flow rate from the usual, and it can be expected to clear the river.
(F) In addition, the size of the dark dye storage tank can be designed according to the estimated precipitation.
