Described PVC board diameter is less than bore diameter 5 ~ 10mm, and the silica gel plate diameter is greater than bore diameter 20 ~ 30mm.
Described PVC plate preformed hole is respectively greater than Grouting Pipe, stack and steel strand diameter 2 ~ 3mm, and silica gel plate preformed hole diameter is then respectively less than Grouting Pipe, stack and steel strand diameter 2 ~ 3mm.
Described cock body is applicable to the anchor cable that all have the slip casting requirement, and the cock body diameter determines that according to bore diameter the cock body preformed hole is determined according to the steel wire bundle number.
The utility model has the advantages that: can cock body be set according to the following Suo Changdu and the sealing of hole segment length of anchor cable in the system rope stage, injecting the fast setting cement with certain flowability in the sealing of hole section behind the following rope starches only, sealing of hole section cement paste solidifies the back and carries out slip casting from injected hole, treat to seal stack after stack flows out underflow, keep the design grouting pressure to stablize slip casting 2 ~ 3 minutes.Cock body is easy to make, and grouting process is simple, and sealing of hole is respond well, effectively guarantees the grouting quality of anchor cable, can satisfy the sealing of hole slip casting requirement of dissimilar anchor cables.This stop grouting plug form of structure is simple, can satisfy the sealing of hole slip casting needs of different apertures, different grouting pressure and different structure form anchor cable, and sealing of hole is respond well, and both can produce in batches also can field fabrication, has good economic serviceability.
