Description
Technical Field
The utility model relates to a slurry shield pipeline technical field, concretely relates to quick leaking stoppage frock of slurry shield circulation mud pipe.
Background
With the rapid development of the infrastructure industry, more and more underground excavation projects are constructed by adopting a shield method, and the slurry balance shield machine is popular due to the advantages of wide application range of stratum, small disturbance to excavated soil mass, high ground settlement control precision and the like. When the slurry balance shield is constructed, a slurry pump is used for pressurizing, bentonite slurry prepared by a ground slurry treatment station is conveyed into a cutter head of the shield machine through a slurry inlet pipeline, the palm residue soil cut by the cutter head of the shield machine is stirred and mixed with the slurry, and the mixture is pumped and discharged by the slurry pump and is conveyed to the ground slurry treatment station through a slurry discharge pipeline.
The pipe wall is abraded and thinned and even damaged due to the fact that rock fragments in the mixture of the slag soil and the slurry rub the pipe wall of the slurry discharging pipeline for a long time, and the abrasion is quite serious especially when the stratum such as granite and cobblestones is tunneled. The worn part of the slurry discharge pipe is mainly in a point form, the shield machine needs to be stopped to repair the pipeline once being worn, and a section of slurry pipe from the shield body inner guard plate to the plate valve position of the shield machine can cause greater safety risk once being worn. The existing repairing method is to stop the leakage by welding a steel plate patch, and the method has long working procedure time and high requirement on the working environment. Or the damaged slurry leaking pipeline is replaced, the method needs to be stopped and the pipe is replaced, the precious tunneling construction time is occupied, the construction period is easily delayed, and the economic effect is poor.
The product is applied to the construction of two slurry balance shield machines of a project A6 standard for water resource allocation engineering construction of the Zhujiang Delta at present, and the work efficiency of slurry pipe slurry leakage repair when the shield machines tunnel granite stratums is remarkably improved.
