Composite cofferdam structure on soft soil foundation in riverway and construction method of composite cofferdam structure
The invention discloses a composite cofferdam structure on a soft soil foundation in a river channel, which comprises a first cofferdam body on an upstream face and a second cofferdam body on a downstream face, a groove is formed between the first cofferdam body and the second cofferdam body, a sheet-pile wall is arranged in the groove, plain soil is backfilled on two sides of the sheet-pile wall, anti-seepage clay is backfilled on the top of the sheet-pile wall, and the anti-seepage clay is filled in the groove. The sheet-pile wall comprises groove-shaped steel sheet piles driven in the width direction of the river channel, and inserting grooves are formed in the middles of the inner walls of the groove bottoms of the groove-shaped steel sheet piles in the vertical direction. The flat steel plates are tightly attached to the outer walls of the groove bottoms of the groove-shaped steel sheet piles, connecting plates extending towards the inserting grooves in the groove bottoms of the adjacent groove-shaped steel sheet piles are arranged at the two side ends of each flat steel plate, and locking openings matched with the inserting grooves are formed in the tail ends of the connecting plates; and the top plate is arranged at the tops of the groove-shaped steel sheet piles and the flat steel plates. The composite cofferdam structure has the advantages of being good in stability and good in water seepage prevention performance.
本发明公开了一种河道内软土地基上的复合围堰结构，包括迎水面的第一堰体和背水面的第二堰体，所述第一堰体和第二堰体间形成的沟槽，所述沟槽中打设有板桩墙，所述板桩墙两侧回填有素土，所述板桩墙顶部回填有防渗黏土，所述板桩墙包括：沿所述河道宽度方向打设的槽型钢板桩，所述槽型钢板桩的槽底内壁中部沿竖直方向设置有插槽；紧贴所述槽型钢板桩的槽底外壁设置的平钢板，所述平钢板的两侧端均设置有向所述相邻槽型钢板桩槽底的插槽延伸的连板，所述连板的末端设置有与所述插槽适配的锁口；设置于所述槽型钢板桩和所述平钢板的顶部的顶板。本发明所述复合围堰结构具有稳定性好、防渗水性好的优点。
