Cement-soil stirring wall construction method
The invention belongs to the technical field of underground engineering construction, and discloses a cement-soil stirring wall construction method. The cement-soil stirring wall construction method comprises the steps that S1, multiple pieces of profile steel are sequentially connected end to end and welded; s2, excavating a soil body to a preset depth by using a TRD chain saw cutter, and injecting cement soil slurry; s3, mixing and stirring the cement-soil slurry and the in-situ soil body by using a TRD chain saw cutter to form a cement-soil stirring wall; s4, the welded profile steel is vertically inserted into the cement-soil stirring wall; s5, after the cement-soil stirring wall is solidified, the profile steel is pulled out through a resonance-free hammer, and cement grout is injected into the pile hole; and S6, the step S5 is repeated till all the profile steel is pulled out, and cement grout is injected. According to the construction method of the cement-soil stirring wall, the multiple pieces of profile steel are sequentially connected end to end and are connected in a welded mode, so that the reinforcing depth requirement of the ultra-deep water cement-soil stirring wall is met, and meanwhile, due to the fact that the profile steel is pulled out, tunneling and crossing of a shield tunneling machine are facilitated through the construction method of the cement-soil stirring wall.
本发明属于地下工程施工技术领域，公开了一种水泥土搅拌墙施工方法。该水泥土搅拌墙施工方法包括：S1、将多个型钢依次首尾相连并焊接；S2、使用TRD链锯刀具挖掘土体至预设深度，并注入水泥土浆液；S3、使用TRD链锯刀具混合搅拌水泥土浆液和原位土体以形成水泥土搅拌墙；S4、将焊接完成的型钢竖向插入水泥土搅拌墙中；S5、水泥土搅拌墙凝固后，使用免共振锤拔除型钢，并向桩孔中注入水泥浆液；S6、重复步骤S5，直至将所有型钢拔除并注入水泥浆液。该水泥土搅拌墙施工方法将多个型钢首尾依次首尾相连并焊接连接，从而满足超深水泥土搅拌墙的加固深度要求，同时该水泥土搅拌墙施工方法同时由于拔除了型钢，便于盾构机掘进和穿越。
