WATER FLOW UNIT, AND UNDERGROUND WATER PRESSURE RELEASE STRUCTURE
To provide a water flow unit and an underground water pressure release structure capable of efficiently releasing underground water pressure by drainage without causing clogging due to floating soil particles.SOLUTION: A water flow unit 1 installed underground comprises: a hollow cylindrical joint pipe 3; a hollow cylindrical upper water flow pipe 4 inserted into one end of the joint pipe; and a hollow cylindrical lower water flow pipe 5 inserted into the other end of the joint pipe across a gap G from the upper water flow pipe. At the other end of the joint pipe, a plurality of grooves 6 are formed by recessing an inner circumferential surface of the joint pipe radially outward with respect to the joint pipe at intervals in a circumferential direction of the joint pipe so as to form a plurality of water flow passages 7 by partitioning with an outer circumferential surface 5b of the lower water flow pipe. The gap between the upper water flow pipe and the lower water flow pipe forms a communication space 8 making the plurality of water flow passages communicate with hollow inside of the upper and lower water flow pipes.SELECTED DRAWING: Figure 1
【課題】浮遊する土粒子によって目詰まりを生じることなく、地中内水圧を排水によって効率よく解放することが可能な通水ユニット及び地中内水圧解放構造を提供する。【解決手段】地中に設置される通水ユニット１であって、中空筒状の継手管３と、継手管の一端側に挿入される中空筒状の上通水管４と、継手管の他端側に、上通水管から隙間Ｇを隔てて、挿入される中空筒状の下通水管５とを備え、継手管の他端側には、下通水管の外周面５ｂで区画して複数の通水通路７を形成するように、継手管の周方向に間隔を隔てて、当該継手管の内周面を継手管の径方向外方へ窪ませて溝部６が複数形成され、上通水管と下通水管との間の隙間は、複数の通水通路をこれら上・下通水管の中空内部へ連通させる連通空間部８を形成する。【選択図】図１
