[0019] The discharge method of the concealed water pipe in the concrete storage area of the dam is as follows:
[0020] 1) Arrange the drainage main pipes in a certain area of the dam to connect the upstream and downstream of the dam; draw the drainage branch pipes from the drainage main pipes to the left and right sides of the dam body, connecting each dam block in the area; draw vertical drainage from the drainage branch pipes of each dam block Branch pipes, along with the concrete pouring positions, are drawn up layer by layer to connect the positions in the dam block. Drainage main pipe, drainage branch pipe and drainage branch pipe can choose DN400, DN300, DN200 and other steel pipes of different sizes depending on the project scale.
[0021] 2). The drainage main pipes are arranged along the river, gradually lowering from the upstream of the dam to the downstream of the dam. The upstream pipe mouth is closed, and the downstream pipe mouth leads to the sump outside the dam...
