Treatment method for underground water geological fracture zone

Abstract

The invention discloses a treatment method for an underground water geological fracture zone, and belongs to the technical field of geological reinforcement devices. The treatment method for the underground water geological crushed zone is achieved based on a grouting device, the grouting device comprises a base, a grouting machine body is installed on the top face of the left side of the base, an adjusting assembly is arranged in an adjusting box, a suction box is welded to the top face of the right rear side of the base, a fixing assembly is arranged on the right side of the suction box, and a suction pipe is arranged on the lower side of the fixing assembly. By arranging the suction pipe, when grouting is carried out, punching equipment is used for punching an area needing drainage, then the number of the fixed assemblies connected is determined according to the punching number, the connected pistons move in a reciprocating mode to carry out suction, and underground water in a broken zone is sucked out through the hose and the suction pipe; and the device can timely discharge underground water in a broken zone, the defect of the underground water to slurry is effectively avoided, the slurry can be rapidly solidified, and the reinforcing effect is better.

Description

technical field [0001] The invention relates to the technical field of geological reinforcement devices, and more specifically, relates to a treatment method for groundwater geological fracture zones. Background technique [0002] Areas of strongly fractured rock caused by faults or densely fractured zones. The former is also called fault fracture zone. The width of the broken zone can reach hundreds of meters or even kilometers, and the length can be tens of meters or even tens of kilometers. According to the stress state when it is formed, it can be divided into three types: compression, torsion and tension. The fissures may be mineral-filled, network-like veins, or may roughly correspond to fault zones. The rupture zone associated with the fault is filled with rock fragments, rubble and clay materials torn from the fault wall. The broken zone is also called the broken zone, and some are re-cemented to form broken rocks, fault breccias, etc. Large-scale fault zones ar...

Problems solved by technology

However, the device still has shortcomings in that when the device is in use, it can only be used for grouting. Because the geological strata in the broken zone are relatively loose, there are many gaps inside, so that the content of groundwater will be large. When grouting, due to the large amount of groundwater in the broken zone, it will be difficult for the slurry to solidify quickly. At the same time, the groundwater will dilute the slurry and affect the quality of the slurry after solidification. In addition, although some existing solutions use The piston and the suction chamber will suck the ground into the suction wall where the piston is located, and then set a water outlet on the outer wall of the suction chamber to realize the suction and removal cycle of groundwater, but this design requires an external water inlet interface. A separate water outlet interface is set on the outer wall of the suction chamber, which makes the design of the entire transmission pipeline complicated. In addition, the piston suction structure needs to set a water outlet on the outer wall of the piston chamber after pumping water into the piston chamber, so it is necessary to set more There are many compensation or switching devices such as one-way valves. In view of this, we propose a treatment method for groundwater geological fracture zones
