WATERPROOF PLATE DEVICE
To take measures when an excessive downward load is applied to a waterproof plate in the upward movement state, in the waterproof plate that moves up from a first underground partition room to close an opening based on the increase in the weight of a water collection bucket due to water collection and provided with downward movement control means to regulate the inadvertent downward movement of the waterproof plate that has moved up.SOLUTION: Assuming that downward movement control means 18 is provided with a downward movement allowance mechanism, when an excessive downward load is applied to a waterproof plate 2, the downward movement regulation by the downward movement control means 18 is released and the waterproof plate 2 is configured to allow the downward movement.SELECTED DRAWING: Figure 3
【課題】防水板が、集水による集水バケットの重量増加に基づき地下の第一仕切り室から上動して開口部の閉鎖をするものに、上動した防水板が不用意に下動するのを規制する下動規制手段を設けたものにおいて、上動状態の防水板に過大な下動負荷が働いた場合の対応をする。【解決手段】下動規制手段18に下動許容機構を設けたものとして、防水板2に過大な下動負荷が働いた場合には下動規制手段18による下動規制を解除して防水板2の下動を許容するように構成する。【選択図】図3
