Rapid underground diaphragm wall obstacle removing method
The invention discloses a rapid underground diaphragm wall obstacle removing method which specifically comprises the following steps: cleaning the ground surface, leveling the ground and hardening the construction ground with concrete. The immersed tube inserting plane position of the rectangular steel tube is marked on the ground; a rectangular steel pipe is inserted, soil in the steel pipe is taken out by combining a crane with soil taking equipment during insertion, and slurry is injected; hoisting the rock into a horizontal high-speed rock crusher by using a crane, and crushing the rock; adjusting the height of the rectangular steel pipe and repeatedly crushing rocks; pulling out the rectangular steel pipe, moving the horizontal position of the steel pipe, and repeating rock crushing construction; the steps are repeated, after all obstacles are removed, the machine is hoisted out, and the rectangular steel pipe is pulled out; according to the method, the high-speed drilling machine is adopted to drive the cutter head to grind the underground diaphragm wall, drilling coring treatment is replaced, and the method has the advantages that slag is easy to remove, and machines are not clamped; the scheme that a protective layer of the underground diaphragm wall is reserved instead of drilling to penetrate through the underground diaphragm wall is adopted, and the method has the advantages of well controlling cracking and deformation of the existing station structure.
本发明公开了一种快速地下连续墙清障方法，具体包括以下步骤，清理地表、整平地面，混凝土硬化施工地面；地面标记矩形钢管沉管插打平面位置；插入矩形钢管，插入的同时利用吊机结合取土设备进行钢管内土体取出，并注入泥浆；利用吊车吊入水平高速碎岩机并碎岩；调整矩形钢管高度，重复碎岩；拔出矩形钢管移动钢管水平位置，重复碎岩施工；重复步骤，全部清障完成后，吊出机械、拔出矩形钢管；本发明中，采用了高速钻机带动刀盘磨碎地下连续墙代替了钻孔取芯的处理，具有容易清渣不卡机械的优点；采用了保留地下连续墙的保护层代替了钻孔打穿地下连续墙的方案，具有良好的控制既有车站结构开裂与变形控制的优点。
