Anchor rope grouting-stop plug

Abstract

The invention discloses a grouting-stop plug for an anchor rope. A silica gel plate is clamped between two PVC (polyvinyl chloride) plates with higher hardness, a bolt is used for fixing the two PVC plates with the silica gel plate to make a disk-shaped plug body, round reservation holes for an injection pipe, an exhaust pipe and a steel strand to penetrate are symmetrically arranged in the disk-shaped plug body, and the disk-shaped plug body is arranged and fixed on an anchor rope; the PVC plate is provided with a PVC plate anchor rope steel strand reservation hole, a PVC plate injection pipe reservation hole and a PVC plate exhaust pipe reservation hole are arranged in the PVC plate; the silica gel plate is provided with a silica gel plate anchor rope steel strand reservation hole, a silica gel plate injection pipe reservation hole and a silica gel plate exhaust pipe reservation hole; and the silica gel plate injection pipe reservation hole and the silica gel plate exhaust pipe reservation hole are smaller than the outer diameters of the anchor rope steel strand, the injection pipe and the exhaust pipe. The grouting-stop plug for an anchor rope has a simple structure, strong applicability, low manufacturing cost and good grouting stop effect, is convenient to use, can ensure the grouting pressure, can meet the requirement of hole sealing of anchor ropes with different apertures, different grouting pressure and different structural forms, and has a good hole sealing effect and good economic applicability.

Description

technical field [0001] The invention relates to the technical field of rock and soil anchoring engineering, and more specifically relates to a grout stopper for anchor cables, which is used for various types of anchor cables that require grouting in various rock and soil anchoring projects such as mining, tunnels and slopes, to prevent the grout from flowing out . Background technique [0002] At present, anchor cables are widely used in geotechnical reinforcement projects (such as slopes, tunnels, etc.) at home and abroad due to their economic applicability and construction convenience. The net grout fully fills the drilling space around the anchor cable body, and a certain grouting pressure is often required during grouting. The cable plays its anchoring role, so the borehole opening needs to be sealed before grouting. Currently commonly used cement slurry sealing and cotton linen sealing methods, these two methods often fail to meet the technical requirements in enginee...

AI Technical Summary

Problems solved by technology

Currently commonly used cement slurry sealing and cotton linen sealing methods, these two methods often fail to meet the technical requirements in engineering practice, such as cement slurry blocking the grouting pipe or exhaust pipe; cement slurry or cotton linen and hole walls Or steel strands and other joints are not tightly combined, resulting in air leakage and grout leakage, so that the grouting pressure cannot meet the requirements and the grouting effect cannot be guaranteed.

Other pulp stop methods, such as hemp silk, wooden wedge and pulp stop tape, are rarely used in engineering due to inconvenient use, poor efficacy or high cost
