Pipe pile and sheet pile combined wading retaining structure

Abstract

The utility model discloses a pipe pile and sheet pile combined wading retaining structure which comprises a prestressed pipe pile, a launching ramp, an upstream face pipe pile, a straining beam and a steel sheet pile. The multiple prestressed pipe piles are evenly distributed at equal intervals and directly penetrate into a soil body bearing layer along the bank of a water area or sequentially penetrate into a water body, a soil layer and the soil body bearing layer in the water area. The launching ramp is laid at the top ends of the prestressed pipe piles, the upstream face pipe piles and the steel sheet piles are arranged on the outer side of the lower position of the launching ramp and sequentially penetrate into a water body, a soil layer and a soil body bearing layer in a water area, and the straining beams are installed at the top ends of the upstream face pipe piles and the steel sheet piles. The foundation structure of the launching ramp is compact in structure, the foundation structure of the launching ramp is constructed in the mode that the pipe piles and the sheet piles are combined, the launching ramp can be supported and protected, cofferdam drainage construction is not needed, the construction work amount, the construction period and the construction cost of the whole structure are greatly reduced, the structure is stable, and reliability is good.
