Telescopic fore shaft steel pipe pile structure for cofferdam closure and working method of telescopic fore shaft steel pipe pile structure
The invention discloses a telescopic locking steel pipe pile structure for cofferdam closure and a working method thereof.The telescopic locking steel pipe pile structure comprises a steel pipe pile and a locking fastener, the steel pipe pile is a hollow pipe, the locking fastener can move in the radial direction of the steel pipe pile, the locking fastener can be inserted into the steel pipe pile in a radial moving mode, and a limiting bolt is arranged on the locking fastener; the limiting bolt can slide and be locked in the radial direction of the steel pipe pile, the locking fastener can be inserted into the steel pipe pile in a manner of rotating around the limiting bolt, the locking fastener is clamped on the steel pipe pile, the first Larsen buckle is fixedly arranged on the peripheral wall of the steel pipe pile, and cofferdam closure is achieved by connecting the first Larsen buckle, the second Larsen buckle and the steel pipe pile. The cofferdam has the beneficial effects that the other steel pipe piles are connected with the first Larsen buckle and the second Larsen buckle by adjusting the moving distance of the locking fastener in the radial direction of the steel pipe piles, so that smooth closure of the cofferdam is achieved, and in addition, before inserting and driving construction of the locking fastener, the locking fastener can be conveniently in place before inserting and driving by adjusting the position of the limiting bolt.
本发明公开了一种用于围堰合龙的伸缩式锁口钢管桩结构及其工作方法，包括钢管桩、锁扣件，钢管桩为中空管，锁扣件本身可在钢管桩的径向方向上移动，锁扣件可径向移动的插设在钢管桩的内部，锁扣件上设置有限位螺栓，限位螺栓可在钢管桩的径向方向上滑动和锁定，锁扣件可围绕限位螺栓旋转的插设在钢管桩的内部，锁扣件卡设在钢管桩上，第一拉森扣固定设置在钢管桩的外周壁上，通过第一拉森扣、第二拉森扣与钢管桩相连接实现了围堰合龙，本发明有益效果：通过调节锁扣件在钢管桩的径向方向上的移动间距，将其它钢管桩与第一、二拉森扣相连接，以实现围堰的顺利合龙，此外，在锁扣件插打施工前，通过调节限位螺栓的位置，方便锁扣件插打前就位。
