Micro-disturbance foundation reinforcement device and underground tunnel envelope structure construction method
The invention discloses a micro-disturbance foundation reinforcement device and an underground tunnel envelope structure construction method, and aims to provide the micro-disturbance foundation reinforcement device and the underground tunnel enclosure structure construction method which can adjust the outer diameter of the same cement soil mixing pile according to the needs, and form a step-shaped cement soil mixing pile through construction, so as to meet different construction needs. The micro-disturbance foundation reinforcement device comprises a mixing pile machine, a high-pressure grouting system and a low-pressure grouting system; the mixing pile machine comprises a drill pipe, the lower end of the drill pipe is provided with a drill bit, and the bottom of the drill pipe is furtherprovided with at least two mixing paddles; the high-pressure grouting system comprises a high-pressure grouting channel which is arranged in the drill pipe and a high-pressure jet channel which is arranged in one of the mixing paddles; and the low-pressure grouting system comprises a low-pressure grouting system which is arranged in the drill pipe and a low-pressure grouting channel which is arranged at the bottom of the drill pipe.
本发明公开了一种微扰动地基加固装置及地下隧道围护结构施工方法，旨在提供一种能够根据需要调节同一水泥土搅拌桩的外径，施工形成阶梯状的水泥土搅拌桩，以满足不同的施工需求的微扰动地基加固装置及地下隧道围护结构施工方法。它包括搅拌桩机，搅拌桩机包括钻杆，钻杆的下端设有钻头，钻杆的底部还设有至少两片搅拌桨；高压注浆系统，高压注浆系统包括设置在钻杆内的高压注浆通道及设置在其中一片搅拌桨内的高压喷射通道；低压注浆系统，低压注浆系统包括设置在钻杆内的低压注浆通道及设置在钻杆底部的低压注浆通道。
