Multi-inlet vacuum-assisted grouting system for discarded pipes
The invention discloses a multi-inlet vacuum-assisted grouting system for discarded pipes, comprising a grouting tube, M grout inlets, a grout pump, an evacuating tube, N evacuating holes, and an evacuating pump. The front end of the grouting tube is connected with one end of a discarded pipe. The grout inlets are arranged in the rear end and/or sidewall of the grouting tube. The grout pump is connected with the grout inlets and is used for injecting grout into the grouting tube through the grout inlets and injecting the grout into the discarded pipe through the grouting tube. The front end of the evacuating tube is connected with the other end of the discarded pipe. The evacuating holes are provided in the rear end and/or sidewall of the evacuating tube. The evacuating tube is connected with the evacuating holes and is used for helping pump the grout from the grouting tube into the discarded pipe. The system has the advantages that grouting speed is higher, grouting power is higher, hierarchical bleeding of cement mortar is eliminated, grouting range is widened, grouting compactness and strength is improved, the potential hazard of later environmental disruption is eliminated.
