Construction method for steel sheet pile cofferdam in hard shale stratum in river
The invention discloses a construction method for a steel sheet pile cofferdam in a hard shale stratum in a river. The construction method comprises the following steps that S1, river sand is taken in situ in the river to build an island; s2, cofferdam steel sheet pile construction is conducted after island building, and cofferdam steel sheet piles are driven to the top of a shale layer; and S3, a plurality of anchor pulling steel sheet piles are arranged behind the cofferdam steel sheet piles in the length direction and the width direction of the cofferdam correspondingly, and the cofferdam steel sheet piles and the ground anchor steel sheet piles are subjected to anchor pulling and fixing through finish rolling deformed steel bars. According to the method, island building is combined with the steel sheet piles, the pull anchors are arranged behind the steel sheet piles, soil reserved on the inner sides of the steel sheet piles provides passive soil pressure, and the problems of stability and water stopping of the steel sheet piles are solved. The method is high in safety, good in water stopping effect and low in construction cost.
本发明公开了一种河中硬质页岩地层钢板桩围堰施工方法，包括以下步骤：S1、在河中就地取河砂进行筑岛；S2、筑岛后进行围堰钢板桩施工，围堰钢板桩打设至页岩层顶；S3、在围堰钢板桩后方沿围堰长度和宽度方向各设置多道拉锚钢板桩，围堰钢板桩与地锚钢板桩用精轧螺纹钢进行拉锚固定。本发明将筑岛与钢板桩相结合的方法，在钢板桩后方设置拉锚，钢板桩内侧预留土提供被动土压力，解决钢板桩稳定性及止水问题。该方法安全性高，止水效果好，施工成本低。
