Abstract
The utility model discloses a synchronous grouting and cleaning device of a shield machine. The synchronous grouting and cleaning device comprises a bentonite slurry storage tank, wherein a bentonite slurry pump is arranged at the bottom of the bentonite slurry storage tank, and a slurry feed pipeline is arranged at the pump outlet of the bentonite slurry pump. The cleaning device provided by the utility model has simple structure and small investment, is convenient to operate, can independently perform circular operation, exerts no influence on the operation of the original synchronous grouting system of the shield machine, and can effectively overcome the difficulties such as cleaning and maintenance of the synchronous grouting system of the shield machine.
Description
Technical field
The utility model relates to the shield machine that a kind of shield tunnel construction is used, and particularly relates to a kind of device that the shield machine filling system is cleaned.
Background technology
In shield-tunneling construction, the shield machine synchronous grouting is the working procedure that shield-tunneling construction is had relatively high expectations.Present shield machine adopts tap water to fling after synchronous grouting is finished usually, most requirements of not considering that pipeline cleans, safeguards after the slip casting.There is following problem in this backwashing manner:
1, because tap water proportion is little, and cement mortar medium sand particle washes and takes away difficulty than great, causes washing time long, and water supply volume is bigger, and is easy to generate sand grains precipitation blocking pipeline.
2, adopt the clear water flushing, cement mortar is easily attached on the grouting pipeline wall, and long time integration can cause the grouting pipeline internal diameter to diminish, even stops up, and it is quite big to stop up back mediation difficulty.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of device that the shield machine filling system is cleaned, this device has characteristics simple in structure, easy to use, can effectively clear up the synchronous grouting system of shield machine, to reduce the blocked probability of synchronous grouting system, improve the operating efficiency of shield machine.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of shield machine synchronous grouting cleaning device comprises the bentonite slurry holding vessel, and described bentonite slurry holding vessel bottom is provided with the bentonite slurry liquid pump, and the pump discharge of described bentonite slurry liquid pump is provided with stock line.
As improvement of the technical scheme, described bentonite slurry liquid pump is a screw pump.
As further improvement in the technical proposal, described stock line is a flexible pipe.
With respect to prior art, the beneficial effects of the utility model are: cleaning device of the present utility model is simple in structure, less investment, and it is easy to operate, can independently circulate, do not influence the work of the former synchronous grouting system of shield machine, can efficiently solve cleaning, the maintenance problems of shield-tunneling construction synchronous grouting system.
Its stock line can be pumped into by the bentonite slurry liquid pump in the pipeline of filling system containing bentonitic cleaning slurries after being connected in the grouting pump of synchronous grouting system of shield machine, can conveniently carry out pipeline and clean.Because swell soil proportion is bigger, take away sand grains easily, and bentonite clay particle can form one deck mud film after attached to tube wall, cement paste is difficult for attached to tube wall, even the cement paste deposition is arranged to be stopped up, also clear up because of the existence of mud film, can effectively reduce the blocked probability of synchronous grouting system, improve the operating efficiency of shield machine than being easier to.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is that the utility model is formed connection diagram.
The specific embodiment
In conjunction with Fig. 1, a kind of shield machine synchronous grouting cleaning device of the present utility model comprises bentonite slurry holding vessel 1, and described bentonite slurry holding vessel 1 bottom is provided with bentonite slurry liquid pump 2, and the pump discharge of described bentonite slurry liquid pump 2 is provided with stock line 3.Cleaning device of the present utility model is simple in structure, less investment, and easy to operate, can independently circulate, do not influence the work of the former synchronous grouting system of shield machine, can efficiently solve cleaning, the maintenance problems of shield-tunneling construction synchronous grouting system.
Cleaning device stock line 3 of the present utility model is connected in the grouting pump 4 of synchronous grouting system of shield machine.In use, the mortar jar 5 of synchronous grouting system stops to supply with slurry, will contain bentonitic cleaning slurries and be pumped into by bentonite slurry liquid pump 2 in the pipeline of filling system, can conveniently carry out pipeline and clean.Because swell soil proportion is bigger, take away sand grains easily, and bentonite clay particle can form one deck mud film after attached to tube wall, cement paste is difficult for attached to tube wall, even the cement paste deposition is arranged to be stopped up, also clear up because of the existence of mud film, can effectively reduce the blocked probability of synchronous grouting system, improve the operating efficiency of shield machine than being easier to.
As preferred embodiment, described bentonite slurry liquid pump 2 is screw pumps.Have simple in structure, safe and reliable, advantages such as use is easy to maintenance, fluid is even continuously, pressure stability.
As further preferred embodiment, described stock line 3 is a flexible pipe, installs to connect conveniently.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
