Novel seepage drainage system of earth and rockfill dam
The invention discloses a novel seepage drainage system of an earth and rockfill dam. The novel seepage drainage system comprises an earth and rockfill dam body, a plurality of S-shaped seepage drainage filter pipes arranged in two columns and multiple rows are arranged in the earth and rockfill dam body, each S-shaped seepage drainage filter pipe is provided with a plurality of discharge outletsand communicates with the corresponding inlet end of a seepage drainage main pipe, the outlet end of the seepage drainage main pipe penetrates through the earth and rockfill dam body and then leads toa grouted rubble seepage drainage ditch located on the downstream portion of the earth and rockfill dam body, and four inverted filter layers which are parallel to the downstream dam slope of the earth and rockfill dam body and are horizontally arranged are arranged on the downstream dam slope of the earth and rockfill dam body. The seepage drainage system is used for accelerating rapid consolidation and settlement of the dam body of the homogeneous earth and rockfill dam, pore water can be efficiently collected and rapidly drained, the drainage filter pipe is not prone to physical blockage,the seepage line of the earth and rockfill dam can further be kept low for a long time, and therefore the stability of the earth and rockfill dam is guaranteed.
本发明公开了一种土石坝的新型排渗系统，其包括土石坝坝体，所述土石坝坝体内部有多个呈两列多排设置的“S”型排渗滤管，所述“S”型排渗滤管设置有多个排出口并且与排渗主管对应的进口端相连通，所述排渗主管的出口端贯穿所述土石坝坝体，然后通向位于所述土石坝坝体下游处的浆砌石排渗沟，所述土石坝坝体的下游坝坡处设置有四层平行于所述土石坝坝体的下游坝坡且水平设置的反滤层。本发明中排渗系统用于均质土石坝加速坝体快速固结沉降，能够高效收集和快速排出孔隙水，且排水滤管不容易物理堵塞，还能够保持土石坝浸润线长期处于较低，以保证土石坝稳定性。
