Full-rotation casing pipe pile pulling and obstacle removing construction method
The invention provides a full-rotation casing pipe pile pulling and obstacle removing construction method, and relates to the technical field of building construction, and the method comprises the following steps: arranging a construction operation area, positioning an old pile, and determining the positions of related facilities in the surrounding environment; pile pulling equipment is determined and comprises a full-slewing drilling machine, a sleeve and a crane, and a pile pulling sequence is formulated; pile pulling equipment is arranged at the corresponding position of the construction site; a casing pipe is installed on the full-slewing drilling machine; the sleeve is driven by the full-slewing drilling machine to pull out the old pile in the mode of drilling downwards from the top along the old pile; the pile pulling quality is checked and accepted; the pile hole of the pulled old pile is backfilled; pulling out the sleeve; and the pile pulling equipment moves, and all old piles are pulled out according to the pile pulling sequence. According to the pile pulling construction method, the old pile dismantling work under the site-limited construction environment can be reasonably planned, scientific construction is achieved, the influence on the surrounding environment and facilities is reduced, and the engineering quality, efficiency and construction safety are guaranteed.
本申请提供了一种全回转套管拔桩清障施工方法，涉及建筑施工技术领域，包括步骤：整理施工作业区域，对旧桩进行定位，并确定周围环境相关设施位置；确定拔桩设备，包括全回转钻机、套管、吊车，制定拔桩顺序；在施工场地相应位置布置拔桩设备；在全回转钻机上安装套管；通过全回转钻机驱动套管沿着旧桩从顶部向下钻进的方式拔除旧桩；对拔桩质量进行验收；对拔除的旧桩桩孔进行回填；拔出套管；拔桩设备移位，按照拔桩顺序完成所有旧桩的拔除。该拔桩施工方法可以对场地受限的施工环境下的旧桩拆除工作进行合理规划，科学施工，减少对周边环境和设施的影响，保障工程质量、效率以及施工安全性。
