Hole collapse prevention grouting and hole guiding method
The invention belongs to the technical field of grouting and hole guiding, discloses a hole collapse prevention grouting and hole guiding method, and aims to solve the problem of high cost caused by the fact that a steel floral tube cannot be recycled during grouting and hole guiding. The method comprises the steps that (1) after a to-be-grouted hole is formed, a clamping groove and a clamping tongue of a steel pipe of a grouting hole guiding device are connected in a clamped mode, and the grouting hole guiding device is pressed into or driven into the grouting hole to a set depth; (2) a grouting pipe is put into the steel pipe to a set depth; (3) the steel pipe is upwards pulled out to separate the clamping groove and the clamping tongue of the steel pipe until the steel pipe is completely pulled out, and a spring and the clamping tongue lose the blocking effect of the steel pipe to drive a first rack to be inserted into a soil body; and (4) grouting is conducted through the grouting pipe, and reinforcement is completed. The steel pipes can be recycled, the cost is reduced, meanwhile, the bearing capacity can be improved, and the reinforcing effect is improved.
本发明属于注浆引孔技术领域，公开了一种防塌孔注浆引孔方法，为了解决注浆引孔时钢花管无法回收导致成本高的问题。本发明包括：（1）待注浆孔形成后，注浆引孔装置的钢管的卡槽与卡舌相互卡接，并将注浆引孔装置压入或者打入到注浆孔内至设定深度；（2）向钢管内放入注浆管至设定深度；（3）向上拔出钢管使得钢管的卡槽与卡舌相互分离直至完全拔出钢管，弹簧和卡舌失去钢管的阻挡作用进而带动第一齿条插入到土体中；（4）通过注浆管进行注浆完成加固。本发明既能够对钢管进行回收利用降低成本，同时又能够提高承载力，提高加固作用。
