Anchor cable pallet in the utility model can realize common anchor cable grouting process, both save the material of hollow grouting cable anchor
Material expense, and make grouting process very simple.To prevent between pallet and lockset, spillage between pallet and spray-up, in addition set
It is equipped with rubber washer and rubber grout cover, plays the role of closure, leakproof.
Concrete operations of the utility model grouting cable anchor in engineering, (1) are punched on prop with anchor cable rig, hole depth
Equal to the pre-buried length of anchor cable.(2) it is installed according to the requirement of installation anchor cable installation.(3) using anchor cable hole as the center of circle, 300-
500mm is radius, and jetting thickness is advisable with 20-30mm.(4) before Gunning material does not solidify, by grout cover, anchor cable pallet, rubber
Washer, lockset are mounted on the exposed cable body of anchor cable in order, then carry out tensioning preload, pretightning force 200kN.(5) by slip casting
The pulp nozzle of machine and the injected hole of pallet connect and carry out slip casting, and grouting process is equal to ordinary hollow anchor rope grouting technique.
The item needed to pay attention in concrete operations, selection is at scar smooth as possible when (1) bores anchor cable hole, guarantee surrounding
Without big concave-convex fluctuating.(2) exposed parts of anchor cable hole and anchor cable must be protected before whitewashing, prevents anchor cable hole from being whitewashed
Material blocks and leads to not slip casting, while also avoiding Gunning material and being solidified in the exposed parts of cable body and influence pallet and dependent part
The installation of part.(3) anchor cable hole is nearby cleared up in time before pallet is installed, in order to avoid spray of the pallet when pre-tightening around anchor cable hole
Layer is extruded extension and blocks anchor cable hole, to influence slip casting effect.
