Construction method of anti-seepage cofferdam structure combined with water interception and drainage
The invention relates to a construction method of an anti-seepage cofferdam structure combined with water interception and drainage, which comprises the following steps of: filling the bottom of a reservoir to form a lower filling component, and paving a lower upstream face protection slope on an upstream slope surface of the lower filling component; stretching steel sheet piles are constructed on the top face of the lower filling component in an inserted and driven mode, and a waterproof curtain is arranged in the lower filling component through curtain grouting construction. A sealing layer is poured on the top face of the lower filling component at the stretching steel sheet pile and the waterproof curtain; the lower filling component is filled with an upper filling component, a water passing box culvert is arranged in the filling process of the upper filling component, and an anti-scour wall and a water falling groove are poured at the outlet position of the water passing box culvert; a working well connected with an outlet of a water intercepting and draining ditch on the bank of the reservoir is mounted at an inlet of the water passing box culvert; filling of the upper filling component is completed; an upper upstream face protection slope is laid on the upstream slope face of the upper filling component, a sealing layer is poured on the top face of the upper filling component, and a downstream face protection slope is laid on the downstream slope face of the cofferdam.
本发明涉及一种与截排水组合防渗围堰结构的施工方法，为：在水库底部填筑形成下部填筑构件，在下部填筑构件的迎水坡面上铺装下层迎水面护坡；下部填筑构件顶面上插打施工有拉伸钢板桩，在下部填筑构件内通过帷幕灌浆施工布置阻水帷幕；在拉伸钢板桩与阻水帷幕处的下部填筑构件顶面上浇筑封闭层；在下部填筑构件上填筑上部填筑构件，在填筑上部填筑构件过程中布置通水箱涵，并在通水箱涵的出口位置处浇筑防冲墙与跌水槽；在通水箱涵的进口处安装有与水库库岸上截排水沟的出口连接的工作井；完成上部填筑构件填筑；在上部填筑构件的迎水坡面上铺装上层迎水面护坡，在上部填筑构件的顶面上浇筑封闭层，在围堰的背水坡面上铺装背水面护坡。
