Urban interchange ramp pile foundation all-casing all-slewing drilling machine dismantling construction method
The invention relates to the technical field of building construction, in particular to an urban interchange ramp pile foundation all-casing all-slewing drilling machine dismantling construction method which comprises the following steps: pile position lofting; laying a working platform; drilling machine equipment is in place after the working platform is laid; pressing down the steel sleeve; the wedge-shaped hammer is embedded; rotating to twist off the old pile; pulling out the twisted-off old pile; the punching grab bucket grabs and exposes the lower-section pile head; impact grabbing ensures thorough obstacle removal; the old pile pulling construction is completed through backfilling and pipe pulling; the urban interchange ramp pile foundation all-sleeve all-rotation drilling machine dismantling construction method has the beneficial effects that the steel sleeve is used, the all-rotation sleeve drilling machine is used for conducting pile pulling operation construction on the cast-in-place concrete pile, the steel sleeve has two functions, on one hand, torque and press-in force provided by top driving equipment are transmitted to the tool bit, and on the other hand, the steel sleeve is used for conducting pile pulling operation on the cast-in-place concrete pile; meanwhile, the effects of supporting the hole wall and preventing the hole wall from collapsing are achieved in the drilling process, and the length of the steel sleeve is 26 m; and a 100t crawler crane is arranged for construction.
本发明涉及建筑施工技术领域，具体为城市立交匝道桩基全套管全回转钻机拆除施工方法，包括以下步骤：桩位放样；铺设工作平台；工作平台铺设完成后进行钻机设备就位；钢套管下压；楔形锤嵌入；回转扭断旧桩；拔除扭断旧桩；冲抓斗抓取、外漏下段桩头；冲抓确保清障彻底；回填拔管完成旧桩拔除施工；有益效果为：本发明提出的城市立交匝道桩基全套管全回转钻机拆除施工方法，使用钢套管，采用全回转套管钻机对混凝土灌注桩进行拔桩作业施工，钢套管有两方面功能，一方面将顶部驱动设备提供的扭矩和压入力传递给刀头，同时在钻进的过程中还起到支护孔壁、防止孔壁坍塌的作用，钢套管长度为26m；并配备100t履带式起重机进行施工。
