[0002] In construction, SMW piles are drilled to a certain depth at the construction site by a multi-axis drilling and mixing machine. At the same time, cement-based strengthening agents are sprayed at the drill bit to repeatedly mix and stir with the foundation soil. Overlapping construction is adopted between each construction unit, and then H-shaped steel is inserted as a stress reinforcement material before the cement-soil mixture hardens. When the cement hardens, a continuous, complete, and seamless underground wall with certain strength and rigidity is formed. After the underground wall reaches the strength standard, the H-shaped steel needs to be pulled out and recycled so that the H-shaped steel can be reused. In the process of removing the H-shaped steel, it is often encountered that the H-shaped steel is difficult to remove because it cannot provide sufficient reaction force support, which affects the recovery of the H-shaped steel and the extraction efficiency of the H-shaped steel. Safety accidents are prone to occur when the reaction force support is weak. Utility Model Content
