Grooving construction method for ultra-deep vertical shaft underground diaphragm wall
The invention discloses a grooving construction method for an ultra-deep vertical shaft underground diaphragm wall. The technical problem that the grooving construction speed of the ultra-deep vertical shaft underground diaphragm wall is low is solved. The method comprises the following steps: (1) measuring and setting out are conducted; (2) a rotary drilling rig is adopted to guide holes to the bottom of the wall, and two holes are guided every time milling is conducted; (3) a soft soil layer and a fully-weathered rock layer are excavated by adopting a hydraulic grooving machine; and (4) theresidual groove body is formed by adopting a double-wheel groove milling machine. According to the grooving construction method, innovation and optimization are conducted on a grooving key technologyof the ultra-deep vertical shaft underground diaphragm wall, underground diaphragm wall grooving machines are combined, compared and selected, an optimal grooving construction method is selected, thevertical shaft grooving construction efficiency is improved, the safety risk is reduced, the construction period is shortened, and high social benefits are achieved.
本发明公开了一种超深竖井地下连续墙成槽施工方法，旨在解决超深竖井地下连续墙成槽施工速率慢的技术问题。该方法包括以下步骤：（1）测量放样；（2）采用旋挖钻机引孔至墙底，每铣次引两个孔；（3）然后采用液压成槽机开挖软弱土层及全风化岩层；（4）剩余槽身采用双轮铣槽机成槽。本发明针对超深竖井地下连续墙成槽关键技术进行创新优化，对地下连续墙成槽机械进行组合比选，选择最优成槽工法，提高竖井成槽施工效率，降低安全风险，节约工期，具有较高的社会效益。
