Connecting structure and method for pile top and bearing platform of PHC anti-pulling pipe pile
The invention discloses a connecting structure and method for a pile top of a PHC anti-pulling pipe pile and a bearing platform, and belongs to the technical field of PHC pipe pile construction.The connecting structure comprises a pipe pile body and a bearing platform foundation, a connecting steel bar is arranged in the pipe pile body, and the pile top of the pipe pile body is connected with a second anchoring steel bar after pile cutting; a first reinforcing steel bar tray and a second reinforcing steel bar tray are arranged on the connecting reinforcing steel bar, the first reinforcing steel bar tray is arranged at the inner bottom of the tubular pile body, the connecting reinforcing steel bar located above the second reinforcing steel bar tray is sleeved with a reinforcing steel bar cage framework, and the part, exceeding the pile top of the tubular pile body, of the reinforcing steel bar cage framework is a first anchoring reinforcing steel bar; the first anchoring steel bars and the second anchoring steel bars are connected with the bearing platform foundation. The quality problems that in the prior art, due to segregation and bleeding of pile core concrete, the concrete strength is reduced, and the self-waterproof performance is reduced are solved, and meanwhile the defect that the overall stress connection performance of the pile top and the bearing platform is insufficient is overcome.
本发明公开了一种PHC抗拔管桩桩顶与承台连接结构及方法，属于PHC管桩施工技术领域，包括管桩本体和承台基础，所述管桩本体内部设有连接钢筋，且管桩本体桩顶截桩后连接有第二锚固钢筋，所述连接钢筋上设有第一钢筋托盘和第二钢筋托盘，所述第一钢筋托盘设置于管桩本体内底部，位于第二钢筋托盘上方的所述连接钢筋外部套设有钢筋笼骨架，所述钢筋笼骨架超出管桩本体桩顶的部分为第一锚固钢筋，所述第一锚固钢筋与第二锚固钢筋与承台基础形成连接。本发明解决了现有技术中因桩芯混凝土发生离析、泌水使得混凝土强度降低、自防水性能降低等质量问题，同时解决了桩顶与承台整体受力连接性能不足的缺陷。
