Dam back seepage monitoring drainage structure capable of being rapidly constructed
The invention discloses an after-dam seepage monitoring drainage structure capable of being rapidly constructed, and relates to the field of hydroelectric and hydraulic engineering, the after-dam seepage monitoring drainage structure comprises a channel, a dam, a dam drainage body and a pressure slope body, and further comprises a concrete connector, an impermeable layer, a measuring weir retaining wall and a permeable drainage channel, the concrete connector is arranged along the two banks of the channel in a full-length mode, and the lower portion of the concrete connector penetrates into a relatively impermeable layer; the impermeable layer is laid downstream from the top of the dam drainage body slope along the channel, the downstream is embedded into the measuring weir retaining wall, the two sides are embedded into the concrete connecting body, the permeable drainage channel is arranged below the impermeable layer and arranged along the bottom of the channel, the upstream is connected with the dam drainage body, and the downstream is arranged in front of the measuring weir retaining wall; the pressure slope body is filled above the impermeable layer and is filled along the channel, the upstream of the pressure slope body leans on the back of the dam, and the downstream slope toe reaches the front of the retaining wall of the measuring weir. A relatively closed anti-seepage structure is defined by combining the anti-seepage layer, the concrete connecting body and the relatively impervious layer, dam seepage and pressure slope seepage are separated, and the seepage flow of the dam can be accurately monitored; the measuring weir retaining wall structure can respectively monitor seepage of the pressure slope body and seepage of the dam, and the stability of the pressure slope body and the stability of the dam can be respectively evaluated.
本发明公开了一种可快速施工的坝后渗流监测排水结构，涉及水电水利工程领域，包括沟道、大坝、大坝排水体和压坡体，还包括混凝土连接体、防渗层、量水堰挡墙和透排水通道，混凝土连接体沿着沟道两岸通长布置，其下部深入相对不透水层，防渗层从大坝排水体边坡顶部沿着沟道向下游铺设，下游嵌入量水堰挡墙中，两侧嵌入混凝土连接体中，透排水通道设置在防渗层下方，沿着沟道底部布置，其上游与大坝排水体连接，下游至量水堰挡墙前；压坡体填筑在防渗层上方，沿着沟道填筑，其上游依靠坝后，下游坡脚至量水堰挡墙前。通过防渗层、混凝土连接体结合相对不透水层围合形成相对封闭的防渗结构，分离大坝渗流与压坡体渗流，可准确监测大坝的渗流量；量水堰挡墙结构可分别监测压坡体渗流与大坝渗流，便于分别评估压坡体与大坝的稳定性。
