Abstract
The invention provides an economical cleaning method, aiming at solving the problems in the prior art that the existing grouting pipeline is difficult to clean, the viscosity reduction of the grout on the outer wall of a pipe can not be effectively prevented so as to cause ground settlement during tunneling construction of shield devices. The device can not reduce the viscosity of the grout and can recycle the wastewater after cleaning. The technical scheme is as follows: a grouting cleaning and switching device and a hydraulic and electrical appliance control device are additionally arranged in the original grouting pipeline, wherein the grouting cleaning and switching device operates through the hydraulic and electrical appliance control device so as to switch automatically between grouting and cleaning. The invention has the beneficial effects that the grouting pipeline can be cleaned effectively to avoid blockage, and the viscosity reduction of the grout on the outer wall of a pipe as well as ground settlement is prevented.
Description
Technical field
The present invention relates to a kind of method that shield structure equipment grouting pipe cleans that is used for.
Background technology
At present, in shield structure equipment tunneling construction, when grouting pipe stops slip casting; The water that cleans grouting pipe inserts pipeline, carries out slip casting and cleans, and rinse water is directly put into section of jurisdiction outer wall earth; Cleaning function is single, the serious consequence that the surface subsidence in the time of also can causing the shield driving construction exceeds standard.So the shield grouting pipeline should satisfy the needs of slip casting, satisfies the cleaning of grouting pipe again, just seems particularly important.There is following problem in the grouting pipe that uses at present: at first, the rinse water of grouting pipe, directly good section of jurisdiction outer wall earth has been pieced together in entering, has reduced the section of jurisdiction outer wall viscosity of injection slurry, has increased the probability of shield structure shield tail place water inlet; Another problem is under the soil property complicated situation, because the reduction of the viscosity of slurries, has increased the permeability of slurries, causes surface subsidence.Therefore existing at present cleaning method still is not enough to the problem that desirable solution grouting pipe cleans.
Summary of the invention
In shield structure equipment tunneling construction; Clean in order to overcome existing grouting pipe; Can not effectively prevent the reduction of injection slurry viscosity of section of jurisdiction outer wall, cause the deficiency of surface subsidence, the invention provides a kind of comparatively economic cleaning method; This device can reach and not reduce the viscosity of injection slurry, and reclaims the waste water after cleaning.
The present invention solves the technical scheme that its problem adopts: in original grouting pipe, increase slip casting and cleaning switching mechanism, hydraulic pressure and electric apparatus control apparatus; Through hydraulic pressure and electrical apparatus control system; Make slip casting and cleaning switching mechanism carry out work, reach the automatic switchover of slip casting and cleaning.
The invention has the beneficial effects as follows: can effectively carry out the cleaning of grouting pipe, guarantee that grouting pipe is not blocked, prevent section of jurisdiction the outer wall reduction and the surface subsidence of injection slurry viscosity.
Another object of the present invention is, has proposed the construction operation method of the automatic switchover of a kind of slip casting and cleaning, and it may further comprise the steps:
(1) with the Grouting Pipe on original shield shell, is replaced with slip casting and cleaning switching mechanism.
(2) hydraulic system is installed
(3) electric apparatus control apparatus is installed.
(4) each device with system installation, be connected after, control the action of hydraulic system through electric control system, make and carry out the work of slip casting and cleaning by slip casting and cleaning switching mechanism.
