The invention discloses a construction method for a steel pipe pile in a PC construction method combined pile. The material waste problem of the steel pipe pile at the present stage is solved. According to the technical scheme, the construction method for the steel pipe pile in the PC construction method combined pile is characterized by comprising the following steps that 1, a limiting device isinstalled on a front pile, the limiting device is provided with a first limiting hole used for limiting the front pile from horizontally displacing and a second limiting hole used for limiting a to-be-installed movable steel pipe pile from horizontally displacing, the front pile is provided with fixed lock catch portions, the movable steel pipe pile sequentially comprises a locking section and anextending section from top to bottom, and the outer side wall of the locking section of the movable steel pipe pile is provided with two movable lock catch portions which are symmetrical left and right about the movable steel pipe pile; 2, the bottom end of the movable steel pipe pile is inserted into the second limiting hole by means of a pile driver; 3, the movable steel pipe pile is pressed down through the pile driver, and the movable lock catch portions of the movable steel pipe pile are buckled with the fixed lock catch portions of the front pile; and 4, the movable steel pipe pile is driven to the designed elevation through the pile driver. The steel pipe pile waste problem is solved.
本发明公开了一种PC工法组合桩中钢管桩的施工方法，解决了现阶段钢管桩的材料浪费的问题。其技术方案要点是一种PC工法组合桩中钢管桩的施工方法，包括如下步骤：S1、在前桩上安装限位装置；限位装置具有限制前桩水平位移的第一限位孔和限制待安装的活动钢管桩水平位移的第二限位孔；前桩具有固定锁扣部；活动钢管桩从上至下依次包括锁定段和延长段，活动钢管桩在锁定段的外侧壁设有两根关于活动钢管桩左右对称的活动锁扣部；S2、使用打桩机将活动钢管桩的底端插入第二限位孔内；S3、使用打桩机将活动钢管桩下压，使得活动钢管桩的活动锁扣部和前桩的固定锁扣部扣合；S4、使用打桩机将活动钢管桩打至设计标高，解决了钢管桩浪费的问题。
