Elastic clamping type connection prestressed concrete pile and construction method
The invention belongs to the technical field of pile construction, and discloses an elastic clamping type connection prestressed concrete pile and a construction method.The elastic clamping type connection prestressed concrete pile comprises an upper-section pile and a lower-section pile which are in butt joint up and down, a connecting rod is arranged on the upper-section pile and protrudes relative to the bottom face of the upper-section pile, and a mounting hole is formed in the lower-section pile; an elastic retaining clamping sleeve is arranged in the mounting hole, the connecting rod can be inserted into the elastic retaining clamping sleeve and clamped with the elastic retaining clamping sleeve, and the bottom face of the upper pile section is attached to the top face of the lower pile section. According to the concrete pile, the butt joint speed of the upper-section pile and the lower-section pile can be increased, and the construction progress is accelerated. The connecting rod has a retaining function after being clamped with the elastic retaining clamping sleeve, and the clamping part is positioned in the lower section pile, so that the connecting part can be effectively prevented from losing efficacy due to long-term influence of a corrosion environment, the upper section pile and the lower section pile are prevented from being separated in an anti-pulling process, and the safety is higher.
本发明属于桩施工技术领域，公开一种弹卡式连接预应力混凝土桩及施工方法，弹卡式连接预应力混凝土桩包括上下对接的上节桩和下节桩，上节桩上设置有连接杆，连接杆相对上节桩的底面凸出，下节桩内设置有安装孔，安装孔内设置有弹性止退卡套，连接杆能够插入弹性止退卡套内，并与弹性止退卡套卡合，上节桩的底面与下节桩的顶面贴合。该混凝土桩能够提高上节桩和下节桩的对接速度，加快施工进程。连接杆与弹性止退卡套卡接后具有止退功能，且卡合部位位于下节桩内部，因此能够有效防止连接处受腐蚀环境的长期影响而失效，避免上节桩和下节桩抗拔过程中脱离，安全性更高。
