Description

本発明は、洪水、冠水などに際し、家屋や建物の玄関口あるいは地下鉄や地下道の入口への浸水を防止するための止水壁に関する。 The present invention relates to a water blocking wall for preventing inundation at the entrance of a house or building or the entrance of a subway or an underground passage in the event of a flood or flood.

近年、狭い地域内に時間当たり１００ミリを越えるような集中豪雨が多発しており、河川の決壊などによる家屋の浸水や都市部において地下鉄や地下道への浸水が問題となっている。このような水害事故の恐れが生じた場合には、通常、土嚢等を積んで水の侵入を阻止することが行われている。このような、土嚢として、特許文献１には、袋状に形成された透水性カバーで構成され、その透水性カバー内に吸水性高分子を有する吸水体を充填するとともに、前記透水性カバーの一部又は全部を覆設する不透水性フィルムを備え水土嚢が提案されている。特許文献２には、雨水検知手段の出力信号により作動して降下路を遮断し、地下への雨水の流入を防止する止水装置などが提案されている。 In recent years, heavy rains exceeding 100 mm per hour have occurred frequently in a narrow area, and inundation of houses due to river breaks and inundation of subways and underpasses in urban areas have become problems. When there is a fear of such a flood accident, usually, sandbags or the like are stacked to prevent water from entering. As such a sandbag, Patent Document 1 includes a water-permeable cover formed in a bag shape, and a water-absorbing polymer having a water-absorbing polymer is filled in the water-permeable cover. There has been proposed a water sandbag provided with an impermeable film covering part or all of it. Patent Document 2 proposes a water stop device that operates by an output signal of rainwater detection means to block a descent path and prevent inflow of rainwater into the underground.

特許文献１に示す水土嚢は、透水性カバーの中に吸水性高分子を有する吸水体を内蔵しているので、浸水あるいは冠水の危険箇所に設置するだけで、吸水性高分子が水を吸収してゲル化し、これらの水によって膨潤した水土嚢同士でバリアを形成し、水漏れすることなく水の浸入を阻止することができるものであるが、一旦、使用した後、再利用することができず、一般家庭や小規模な店舗や工場などにおいてコスト的に不利であるとともに、水を吸収して止水用のバリアとすることから、初期の段階において、雨水などによって流れてしまうことが懸念され、水を吸収して安定化するまで、監視する必要があるなど、使い勝手が悪い。一方、特許文献２に示す地下への雨水流入防止装置は、地下への雨水の流入を防止するものであって、地下へと通じる降下路にワイヤにより吊り下げた止水体を昇降自在に配置し、モータによって駆動し、雨水検知手段によって、モータを制御することによって、止水装置は作動して地下への雨水の流入を阻止するものであるから、極めて導入コストが高いため、大規模な施設等では導入できても、小さな事業所や店舗、或いは個人の住宅等の小規模な施設や建物に普及させるのは導入コストの面で導入が困難であった。 Since the water sandbag shown in Patent Document 1 has a water-absorbing body having a water-absorbing polymer in a water-permeable cover, the water-absorbing polymer absorbs water just by being installed in a place where it is flooded or flooded. It is a gel that forms a barrier between the water sandbags swollen by these waters, and can prevent water intrusion without leaking water. However, it is disadvantageous in terms of cost in ordinary households, small stores, factories, etc., and because it absorbs water and becomes a barrier for water stoppage, it may flow due to rainwater etc. at an early stage. Concern is inconvenient and it is necessary to monitor until water is absorbed and stabilized. On the other hand, the underground rainwater inflow prevention device shown in Patent Document 2 prevents the inflow of rainwater into the underground, and a waterstop suspended by a wire is arranged in a descending path leading to the underground so as to freely move up and down. Since the water stop device operates by the motor and is controlled by the rainwater detection means to prevent the inflow of rainwater to the underground, the introduction cost is extremely high, so large-scale facilities Even if it can be introduced, it is difficult to introduce it in small establishments and stores, or small facilities and buildings such as private houses because of the introduction cost.

本発明は上述した問題点に鑑みてなされたものであり、小規模な施設や個人住宅において、導入コストを低減することができるとともに、雨水の流入を確実に防止して家屋あるいは地下浸水を防止することができる止水壁を提供することを目的とする。 The present invention has been made in view of the above-described problems, and can reduce the introduction cost in a small-scale facility or a private house, and reliably prevent the inflow of rainwater to prevent inundation of houses or underground.
