Construction method of buckle steel pipe pile underground diaphragm wall composite cofferdam
A construction method for a composite cofferdam of an underground diaphragm wall of a lock catch steel pipe pile comprises the steps that the lock catch steel pipe pile is vibrated and sunk through a vibratory hammer, a rotary drilling rig is used for conducting rotary drilling on the lock catch steel pipe pile by 1 m, a reamer bit is used for reaming a drill hole which is drilled by 1 m after rotary drilling, and then the vibratory hammer is used for vibrating and sinking the steel pipe pile by 1 m; rotary excavating and reaming are repeated for multiple times, so that the lock catch steel pipe reaches the designated position of the rock stratum; a reinforcement cage and an underwater concrete pouring guide pipe are put down, and underwater concrete is poured after holes are cleaned till the concrete surface exceeds the lock catch steel pipe pile by 3 m; and after the strength of the concrete is reached, the lock catch steel pipe pile-underground diaphragm wall composite cofferdam is formed. The method is novel in design, clear in target and easy and convenient to operate, and the cofferdam construction problems of high water depth flow velocity, thin covering layer and deep bed rock in the inland river are solved.
一种锁扣钢管桩地下连续墙复合围堰施工方法，采用振动锤振动下沉锁扣钢管桩，使用旋挖钻机在锁扣钢管桩内旋挖钻进1m，使用扩孔钻头将旋挖后的1m钻孔进行扩孔，再用振动锤将钢管桩振动下沉1m；多次重复旋挖和扩孔，使锁扣钢管直至到达岩层的指定位置；下放钢筋笼与水下混凝土灌注导管，清孔后灌注水下混凝土，直至混凝土面超过锁扣钢管桩3m为止；当混凝土强度达到后，就形成了锁扣钢管桩‑地下连续墙复合围堰。所述方法设计新颖、目标明确、操作简单便捷，解决了内陆河流中水深流速快覆盖层薄且入基岩深的围堰施工问题。
