Underwater rock-socketed concrete pile and construction method thereof
The invention discloses an underwater rock-socketed concrete pile. The underwater rock-socketed concrete pile comprises a steel pipe pile and a cast-in-place concrete pile, wherein the bottom of the steel pipe pile is inserted into the top face of bed rock, the outer wall of the steel pipe pile is provided with a female and male locking opening, a reinforcement cage is arranged inside the steel pipe pile, the cast-in-place concrete pile is formed inside the steel pipe pile and at the position of a bed rock drilled hole below the steel pipe pile by pouring underwater concrete, the steel pipe pile, the reinforcement cage, the cast-in-place concrete pile and the bed rock are integrally formed, the invention further discloses a steel cofferdam structure, the invention further discloses a construction method of the underwater rock-socketed concrete pile, and the invention further discloses a construction method of the steel cofferdam structure. According to the underwater rock-socketed concrete pile and the construction method thereof, under the conditions that a reservoir cannot be emptied and the water level of a reservoir area is high, the stability of the steel pipe pile driven into deep water is improved, and the problem that the pipe pile topples over due to the fact that the peripheral water pressure is larger during dewatering in a foundation pit is well solved, and meanwhile the problems that dam foundation rock is hard and the pipe pile is difficult to drive in are solved.
本发明公开了一种水下嵌岩混凝土桩，包括：钢管桩，其底部插至基岩顶面，所述钢管桩外壁具有阴阳锁口，所述钢管桩内部设有钢筋笼；混凝土灌注桩，其通过灌注水下混凝土形成于所述钢管桩内部以及下方的基岩钻孔处，所述钢管桩、钢筋笼、混凝土灌注桩与基岩一体成型。本发明还公开了一种钢围堰结构。本发明还公开了一种水下嵌岩混凝土桩的施工方法。本发明还公开了一种钢围堰结构的施工方法。本发明能够在不能放空水库且库区高水位的情况下，提高钢管桩打入深水后的稳定性，很好的解决基坑内降水时外围水压力较大造成管桩倾倒的问题，同时也解决了坝基岩石坚硬，管桩打入困难的问题。
