Water stop structure for cross joint of gravity dam
The invention discloses a gravity dam transverse joint water stop structure which is suitable for the situation that a plurality of galleries are arranged in a gravity dam, the water stop structure comprises water stop pieces, a first water stop piece and a second water stop piece, the first water stop piece and the second water stop piece are arranged in pairs, and the first water stop piece and the second water stop piece are perpendicular to a transverse joint and embedded in the transverse joint; the drainage floral tube is vertically arranged between the first upstream water stop strip and the second upstream water stop strip; one end of the drainage pipe is communicated with the drainage floral pipe, and the other end of the drainage pipe is communicated with the gallery. The structure is simple, construction is convenient, the drainage floral tube is arranged between the two water stop pieces, and the anti-seepage drainage treatment effect of transverse joint water stop can be enhanced; under the extreme condition of water stop failure, the drainage pipe communicated with the drainage floral pipe can be used for discharging upstream seepage water in time, upper blocking and lower discharging are truly achieved, and the purpose of reducing uplift pressure of the dam body is achieved.
本发明公开了一种重力坝横缝止水结构，适于重力坝内设置有若干廊道的情况，所述止水结构包括：止水片，包括成对设置的上游第一止水片和上游第二止水片，所述上游第一止水片和上游第二止水片与横缝相垂直且镶嵌在横缝内；排水花管，沿竖向设置在上游第一止水片和所述上游第二止水片之间；排水管，一端与所述排水花管连通，另一端与所述廊道连通。本发明结构简单，施工方便，在两道止水片中间设置排水花管，能够增强横缝止水的防渗排水处理效果；在止水失效的极端情况下，可以利用与排水花管连通的排水管将上游渗水及时排出，真正意义上做到了上堵下排，达到了降低坝体扬压力的目的。
