Slurry balance type tube push bench and circulative slurry deslagging method

Abstract

The invention discloses a slurry balance type tube push bench and a circulative slurry deslagging method utilizing the same. The internal cavity of the slurry balance type tube push bench is internally provided with at least one driving system and at least one circulative deslagging system used for discharging sludge in a slurry cavity, wherein the output end of the driving system is connected with a cutter head by penetrating though a partition plate; and in the process of performing circulative slurry deslagging by virtue of the slurry balance type tube push bench, the slurry is discharged into the slurry cavity by virtue of the at least one circulative deslagging system; the soil and slurry in the slurry cavity are fully mixed to form sludge, the sludge in the slurry cavity is discharged into a slurry pool by virtue of at least one circulative deslagging system, and the discharged sludge precipitates in the slurry pool so as to form slurry. The slurry balance type tube push bench and a circulative slurry deslagging method utilizing the slurry balance type tube push bench can be used for improving the deslagging efficiency, are simple, convenient and reliable in construction, are safe and convenient in operation, and are used in the field of non-excavation engineering construction.

Description

technical field [0001] The invention relates to the field of non-excavation engineering construction, in particular to a mud-water balanced pipe jacking machine and a method for using the pipe jacking machine to perform mud circulation and slag discharge. Background technique [0002] At present, the pipe jacking construction method is mostly used in the construction of pipeline trenchless engineering, that is, the jacking force generated by the pipe jacking machine is used in the working pit to overcome the friction between the pipeline and the surrounding soil, and the pipeline is pushed into the soil according to the designed slope, and To transport the earth away, most of the pipe jacking machines are of mud-water balance type and earth pressure balance type. In terms of soil pressure control on the cutting surface of excavation, the muck of the earth pressure balance type is in the shape of mud balls, and the muck of the mud-water balance type is in the form of mud , bu...
