Underwater rock-socketed steel sheet pile cofferdam and construction method thereof
The invention discloses an underwater rock-socketed steel sheet pile cofferdam. The cofferdam comprises a fence, an inner support fixed in the fence and a fence inserting groove formed in an underwater bottom foundation rock stratum, wherein the bottom of the fence is inserted into the fence inserting groove, an inner anti-seepage body is arranged in the fence inserting groove and located on the inner side of the fence, an outer anti-seepage body is arranged in the fence inserting groove and located on the outer side of the fence, a slope toe anti-seepage body is arranged at the joint of the outer side of the fence and the foundation rock stratum at the bottom in water, and a plurality of pieces of anti-seepage soil cloth dividing the slope toe anti-seepage body into a plurality of layers are arranged in the slope toe anti-seepage body. The underwater rock-socketed steel sheet pile cofferdam is good in water stopping effect, convenient to construct and capable of reducing the construction cost. The invention further discloses a construction method of the underwater rock-socketed steel sheet pile cofferdam. The construction method comprises the steps of drilling and grooving; mounting the fence; backfilling cohesive soil; and performing layered backfilling. According to the underwater rock-socketed steel sheet pile cofferdam and the construction method thereof, the water stopping effect is good, construction is convenient, and the construction cost can be reduced.
本发明公开了一种水中嵌岩钢板桩围堰，包括围栏、固定于围栏内的内支架以及设于水中底部基础岩层上的围栏插槽，围栏的底部插于围栏插槽中，围栏插槽内于围栏的内侧设有内防渗体，围栏插槽内于围栏的外侧设有外防渗体，围栏外侧与水中底部基础岩层的交接处设有坡脚防渗体，坡脚防渗体中设有多块将坡脚防渗体分隔成多层的防渗土布。该水中嵌岩钢板桩围堰止水效果好、施工方便以及能够降低施工成本。本发明还公开了一种水中嵌岩钢板桩围堰的施工方法，包括步骤：钻孔成槽；围栏安装；回填黏性土；分层回填。该水中嵌岩钢板桩围堰及其施工方法止水效果好、施工方便以及能够降低施工成本。
