Embodiment

[0029] Embodiment: The raw material in the raw material box 1 is pumped into the diversion valve 10 through the pump 9, the raw material is divided into several diversion pipes 11 through the diversion valve 10, and the raw materials are respectively diverted to several diversion pipes 11 through several diversion pipes 11. In the mortar suction cylinder 2, a number of conical columns 4 are pushed by high-pressure raw materials, and the telescopic convex boxes 5 are respectively driven by several pushed conical columns 4. Inner telescopic movement, and at the same time, several telescopic spring columns 7 are elastically contracted through several telescopic convex blocks 5, and the raw material liquid is respectively drained into the gaps in several holes through several mortar suction cylinders 2, and the raw material is discharged by high pressure. Squeeze into several gaps. When the gaps are full, the hydraulic pressure on both sides of several conical columns 4 is the same...

Abstract

The invention discloses an artificial anchor hole grouting device for preventing mortar leakage and insufficient grouting. The beneficial effect of the invention is that several guide bearing seats are closely attached to the wall through a negative pressure fixing structure, thereby achieving The reaction force generated during the grouting process of the grouting structure is circulated, and at the same time, the effect of stabilizing several mortar suction cylinders is achieved through atmospheric pressure extrusion, and the raw materials are squeezed into several gaps by high pressure through the shunt connection structure and the stirring anti-solidification structure , so as to achieve close attachment watering.

Description

technical field [0001] The invention relates to the technical field of anchor hole grouting, in particular to an artificial anchor hole grouting device for preventing mortar leakage and insufficient grouting. Background technique [0002] When the foundation pit support construction is carried out in the confined water stratum, it is often encountered that the anchor hole construction breaks through the confined aquifer, resulting in water inrush from the anchor hole. At this time, there is water flowing out of the anchor hole continuously, and the success rate of anchor grouting is very low if it is not blocked. The traditional construction method is generally to use cement water glass double slurry grouting to seal or use grout stop ring pressure grouting. The use of cement water glass double grout construction is only effective for slight water gushing, and the construction cost is high, and the anchor quality is not reliable; if the grout stop ring is pressure grouted, ...
