Anti-seepage stable cofferdam structure and construction method thereof
The invention provides an anti-seepage stable cofferdam structure and a construction method thereof. The cofferdam structure comprises a cofferdam foundation, and further comprises a berm and a cofferdam body which are sequentially arranged from the upstream face to the downstream face; the cofferdam foundation is filled with the berm; the berm and the cofferdam foundation are filled with the cofferdam body; sand cushion layers are laid on the upstream face of the berm and the upstream face of the cofferdam body; mold bag concrete protection slopes are laid outside the sand cushion layers; an anti-seepage wall is arranged in the berm; a composite geomembrane is buried in the cofferdam body; the lower end of the composite geomembrane is connected to the upper end of the anti-seepage wall in a pouring manner; and the berm and the anti-seepage stable cofferdam structure are each of a trapezoid structure. According to the anti-seepage stable cofferdam structure and the construction method thereof, the stability of the cofferdam structure can be maintained without increasing the height of a cofferdam or decreasing the gradient of the cofferdam, the size of the cofferdam structure is reduced, the situation that the work amount of the cofferdam structure is sharply increased is avoided, and the project cost is remarkably reduced.
本发明提供了一种防渗稳固的围堰结构及其施工方法，围堰结构包括围堰基础，还包括由迎水面至背水面依次设置的戗堤和围堰主体，戗堤填筑在围堰基础上，围堰主体填筑在戗堤和围堰基础上，戗堤、围堰主体的迎水面均铺设有砂垫层，砂垫层外铺设有模袋混凝土护坡；戗堤的内部设置有防渗墙，围堰主体的内部埋设有复合土工膜，复合土工膜的下端浇筑连接在防渗墙的上端；戗堤和防渗稳固的围堰结构均呈梯形体结构。本发明可不用提升围堰的高度以及减缓围堰的坡度而又可以维持其稳定性，围堰结构的体积得到降低，避免急剧地加大围堰结构的工程量，显著降低了工程的费用。
