PHC supporting pipe pile construction method for building crown beam in advance
The invention discloses a PHC supporting pipe pile construction method for building a crown beam in advance. The method comprises the following steps that S1, the position and elevation of the crown beam are measured on the ground, a foundation trench is excavated according to the measurement result, and the position and elevation of the crown beam are rechecked; S2, the positions of needed PHC pipe pile cores and reserved pipes are measured at the bottom of the foundation trench, corresponding prefabricated pile casings are placed with the PHC pipe pile cores as the centers, and the corresponding reserved pipes are inserted into the bottom of the foundation trench according to the measured positions of the reserved pipes; S3, a cushion layer is poured at the bottom of the foundation trench, the crown beam is constructed after the cushion layer reaches the strength, a formwork is removed after the crown beam reaches the strength, and earthwork around the foundation trench is leveled to be flush with the top face of the crown beam; S4, corresponding PHC pipe piles are constructed in the pre-buried prefabricated pile casings to reach the designed elevation; S5, reinforcement cages are placed in the pre-buried prefabricated pile casings, and then concrete is poured to be flush with the top face of the crown beam; and S6, high-pressure jet grouting pile construction is carried out through the reserved pipes. The method is simple and easy to construct, the construction quality can be improved, the construction progress can be accelerated, and the construction cost can be saved.
本发明公开了一种先筑冠梁的PHC支护管桩施工方法，其步骤如下：S1、在地面测量冠梁的位置和标高，根据测量的结果开挖基槽，并复核冠梁的位置和标高；S2、在基槽底部测量出所需PHC管桩桩芯和预留管的位置，以各PHC管桩桩芯为中心放置对应的预制护筒，根据各预留管测量的位置在基槽底部插入对应的预留管；S3、在基槽底部上浇筑垫层，垫层达强度后施工冠梁，冠梁达强度后拆模，将基槽周边的土方平整至与冠梁顶面齐平；S4、在各预埋的预制护筒中施工对应的PHC管桩至设计标高；S5、在各预埋的预制护筒放置钢筋笼，接着浇筑混凝土至与冠梁顶面齐平；S6、通过各预留管进行高压旋喷桩施工。该方法简单易施工，可以提高施工质量，加快施工进度，节约施工成本。
