Construction method of multi-axis high-pressure-spraying diaphragm wall
The invention discloses a multi-shaft high-pressure-spraying diaphragm wall construction method which comprises the steps that at least two drill rods are transversely arranged to form a drill rod set, the adjacent drill rods are not engaged, the drill rod set is driven by a rotary power mechanism to drill a stratum, and in the drilling process, fluid cutting is conducted on the stratum between the adjacent drill rods through a nozzle at the same time; downward cutting is performed through the cutting plate; in the drilling process and/or the process of lifting the drill rod group, a condensation material is injected into the drilled and sprayed original stratum, and the condensation material and other materials of the original stratum are condensed to form a wall body; the multiple drill rods are connected through the cutting plate, so that the drilling construction efficiency is greatly improved, the nozzles are arranged on the cutting plate, high-pressure jet cutting can be conducted on unengaged stratums between the adjacent drill rods, and the quality problem that a traditional high-pressure jet diaphragm wall leaks jet is solved.
本发明公开了一种多轴高喷防渗墙施工方法，通过至少两根钻杆横向排布形成钻杆组，相邻钻杆之间不咬合，钻杆组在回转动力机构的驱动下对地层进行钻进，在钻进过程中，同时通过喷嘴喷射流体对相邻钻杆之间的地层进行流体切割，并通过切割板向下切割；在钻进过程中，和或提升钻杆组的过程中，向钻喷后的原始地层内注入凝结材料，凝结材料与原始地层其他物料凝结形成墙体；本发明通过切割板连接多根钻杆，使得钻孔施工效率大大提高，通过在切割板上设置喷嘴，可对相邻钻杆之间未咬合地层进行高压喷射切割，避免了传统高喷防渗墙漏喷的质量问题。
