Integrated double-bag enlarged anchor cable

Abstract

The invention discloses an integrated double-bag enlarged anchor cable which comprises a positioning head guard and a grouting pipe. A reverse-osmosis hole sealing bag and a reverse-osmosis enlarged bag are respectively fixed to the positions, close to two ends, on the grouting pipe by using a pair of press hoops, a clamping head is installed on the outer sides of the press hoops at two ends of two bag bodies respectively in a tightly-attached mode, symmetric through holes are formed in two sides of each clamping head respectively, a gland is arranged at the position of a grouting hole formed in the head guard, a locking nut is arranged at the center of the gland, guide pipes passing through the bags are respectively fixed in the through holes formed in the clamping heads corresponding to the two bag bodies, an anchor cable from the gland to the rear end of the grouting pipe penetrates into the cavities of the guide pipes, corresponding to the two bag bodies, on two sides respectively, a one-way grouting valve is arranged on the grouting pipe sections in the two bag bodies respectively, and a water-air separating filter valve is arranged in the airtight section between the hole sealing bag and the enlarged bag. The two bag bodies are both made of reverse-osmosis antiseptic cloth.

Description

Technical field: [0001] The invention relates to a fixed building, in particular to an integrated double-capsule expansion anchor cable used in building engineering foundation reinforcement. Background technique: [0002] The expansion anchor cables used in the existing building engineering foundation reinforcement all install a positioning head guard at the end of the four anchor cables, and use two compression hoops on the anchor cables to fix an expansion capsule at the rear end of the anchor cables. A clip is respectively fixed on the outer ends of the two compression hoops of the expander capsule and the anchor rod at the rear end of the head guard, and a grouting pipe and a drainage air pipe are respectively penetrated through holes on both sides of the clips at both ends of the compression hoop . This traditional single-capsule expansion anchor cable, in the process of slurry solidification, easily causes pores and cracks due to the evaporation of water, which re...

AI Technical Summary

Problems solved by technology

This kind of traditional single-capsule expansion anchor cable, in the process of slurry solidification, will easily cause pores and cracks due to the evaporation of water, which will reduce the pullout strength of the anchorage; in addition, because of the natural grouting method, not only the grouting is slow, but also The material is not easy to enter the cracks in the soil layer, which affects the quality of the project
