Construction method for removing underground secant piles through full-casing full-slewing drilling machine
The invention relates to a construction method for removing underground secant piles by a full-casing full-slewing drilling machine, which comprises the following steps: construction preparation: leveling a site, constructing a concrete guide wall, and operating the full-casing full-slewing drilling machine in place to align with the secant piles; breaking the pile body: operating a breaking pipe to be inserted into the orifice; after the breaking pipe completely extends into the hole opening, a grabbing device is used for fishing all broken materials of the broken pile body; the breaking pipe is lengthened by one section, and the breaking pipe continues to be lengthened after the operations of breaking the pile body and taking out residues are repeated; perpendicularity measurement and control: hoisting and placing a first section of casing pipe, and measuring and controlling the perpendicularity of the casing pipe; pressing in the first section of sleeve; a second section of casing pipe is connected; the first section of casing pipe is taken out; in-depth operation, pipe connecting and soil taking are conducted in sequence till the sleeve reaches the rock surface or the designed hole depth; and sandy soil is backfilled, specifically, the casing pipe is backfilled with the sandy soil, and breaking of the underground secant pile is completed. The efficiency of removing underground secant piles by using the full-casing full-slewing drilling machine can be improved.
本申请涉及一种全套管全回转钻机清除地下咬合桩的施工方法，其包括步骤：施工准备：平整场地，将砼导墙施工好，操作全套管全回转钻机就位对准咬合桩；破除桩体：操作破除管插入孔口；取出残留物：当破除管完全伸入孔口后，使用抓取装置对所有的破除桩体碎料进行捞取；接长破除管：将破除管接长一段，并重复破除桩体和取出残留物的操作后继续接长破除管；测控垂直度：吊装安放第一节套管，测控套管的垂直度；第一节套管压入；接入第二节套管：将第一节套管取出；深入操作：依次接管、取土直至套管到达岩面或设计孔深；回填砂土：接着向套管内回填砂土，完成地下咬合桩的破除。本申请能够提升使用全套管全回转钻机清除地下咬合桩的效率。
