Underground pressure control system and rotary spraying construction method thereof
The invention relates to an in-ground pressure control system. Comprising a drilling machine, a drilling tool, a grouting module and a slurry pumping module, the grouting module comprises a slurry spraying opening, an orifice sealer, a drilling tool fluid director, a grouting pipe and a grouting pump; the slurry pumping module comprises a slurry pumping opening, an orifice sealer, a slurry pumping valve, a negative pressure pump, a drilling tool slurry pumping valve, a slurry pumping pipe and a slurry box; and the orifice sealer is sleeved on the drilling tool and is positioned at the junction of the drilling tool and the orifice. According to the in-ground pressure control system, in the jet grouting construction process, the in-ground pressure can be reasonably adjusted, winding of a drilling tool on the surrounding hole wall during working is reduced, control over the pile diameter is facilitated, and the effect quality of the jet grouting construction operation is improved. Furthermore, according to the underground pressure control system provided by the invention, due to the arrangement of an orifice sealer and a drilling tool sealer, the drilling tool can be transversely arranged, obliquely arranged or vertically arranged.
本发明是一种地内压力控制系统；包括钻机、钻具，还包括注浆模块以及抽浆模块；注浆模块包括喷浆口、孔口密封器、钻具导流器、注浆管、注浆泵，抽浆模块包括抽浆口、孔口密封器、抽浆阀门、负压泵、钻具抽浆阀门、抽浆管以及泥浆箱；孔口密封器套设在钻具上并位于钻具与孔口的交界处。本发明所提出的地内压力控制系统，能够在旋喷施工时，合理调节地内压力，减小钻具工作时对周围孔壁的绕动，并且有利于桩径的控制，提高旋喷施工作业的效果质量。进一步，本发明所提出的地内压力控制系统，由于孔口密封器、钻具密封器的设置，使得钻具能够横向设置、倾斜设置或者竖直设置。
