Cast-in-place pile post-grouting device and construction method
The invention discloses a cast-in-place pile post-grouting device. The cast-in-place pile post-grouting device comprises a pile hole operation table; the post-grouting assembly comprises a reinforcement cage, hoisting equipment, at least one pair of grouting main pipes and a plurality of grouting branch pipes, one grouting main pipe can be connected with two to three grouting branch pipes from top to bottom, a grouting opening is formed in the bottom of the grouting main pipe, the top of the grouting main pipe is communicated with the grouting equipment through a pipeline, and grouting holes are formed in the grouting branch pipes; the jacking assembly comprises a jacking rod and a bidirectional hydraulic cylinder; and the lowering assembly is detachably installed on the pile hole operation table, and the lowering assembly comprises four sets of lowering motors and rollers. The invention further discloses a cast-in-place pile post-grouting method. It can be ensured that the grouting branch pipe enters the side wall of the pile hole to be fully filled, the grouting uniformity is improved, meanwhile, the grouting operation is in a smooth state, and the construction quality and the firmness strength of a pile foundation are improved.
本发明公开了一种灌注桩后注浆装置，包括：桩孔操作台；后注浆组件，其包括钢筋笼及吊装设备、至少一对注浆主管、多个注浆支管，一个注浆主管上自上至下可连接两到三个注浆支管，所述注浆主管底部设有注浆口、顶部通过管路与注浆设备连通，所述注浆支管设有注浆孔；顶紧组件，其包括顶紧杆、双向液压缸；下放组件，其可拆卸安装于所述桩孔操作台，所述下放组件包括四组下放电机与辊轮。本发明还公开了一种灌注桩后注浆方法。本发明能够确保注浆支管进入桩孔侧壁充分填充，提高注浆均匀性，同时使注浆作业处于通畅状态，提高桩基的施工质量和牢固强度。
