Description
Technical field
The utility model relates to Shield Construction Technique field, particularly a kind of grouting pipeline for shield machine rinse-system.
Background technology
Shield machine is as current state-of-the-art tunnel piercing ultra-large type special equipment, and be realization driving, be unearthed, supporting etc. once excavates the high-tech construction equipment of cavitation, is widely used in the construction of tunnel such as urban track traffic, railway, highway, municipal administration, water power.
In work progress, when after shield machine driving, certain space will be there is between section of jurisdiction and stratum, between section of jurisdiction and shield tail housing, for controlling stratum deformation, reduce sedimentation, and be conducive to improving the early stage stable of the impervious and pipe-plate lining in tunnel, need after the wall of section of jurisdiction, between hoop, adopt the mode of synchronous grouting to fill slurries.Synchronous grouting is absolutely necessary cargo handling operation in shield-tunneling construction, and its slip casting effect directly has influence on the sedimentation on tunnel water proofing quality and earth's surface.The setting time of slurries is generally at 3 to 10 hours, and in therefore slip casting process, slurries are very easy to solidify.Because the slurries sand content of preparation is many, can not make mobility and plasticity all well slurries, the sand in slurries is easy to precipitation, blocking Grouting Pipe.Add wall scroll grouting pipeline from pump to shield tail nearly 30 meters.Above various reasons causes grouting pipeline often to block, thus causes shield-tunneling construction often to shut down.Want Grouting Pipe not block, only way is exactly often cleaning.Traditional cleaning way is that segmentation is taken apart and rinsed well with water pipe.This method wastes time and energy, and causes idle cost to shield-tunneling construction.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of grouting pipeline for shield machine rinse-system; road gas circuit of catchmenting is integrated; flushing operation can be carried out to many Grouting Pipe simultaneously; the pipeline in shield body can not only be rinsed; the pipeline that can also connect in back flush chassis; can washing time be saved, can not shutdown be caused again, can ensure that construction is worked continuously.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of grouting pipeline for shield machine rinse-system, comprise and stir the tunneling synchronous mud injecting pump that chassis is communicated with and the main Grouting Pipe be communicated with described tunneling synchronous mud injecting pump with mortar, described main Grouting Pipe is provided with point Grouting Pipe of more than two, and main Grouting Pipe is provided with main pneumatic ball valve; Described each point of Grouting Pipe is all serially connected with point pneumatic ball valve and pressure sensor, and before entering point Grouting Pipe, be also provided with the air pump be communicated with main Grouting Pipe, wherein, the cleaning hose that air pump is connected with main Grouting Pipe is provided with three way cock, the other end of three way cock and cross current.
Further, the cleaning hose between three way cock and main Grouting Pipe is serially connected with control ball valve.
Further, the main Grouting Pipe between main pneumatic ball valve and point Grouting Pipe is serially connected with flow meter.
Further, described point Grouting Pipe is four.
Adopting the beneficial effect that produces of technique scheme to be: operating principle of the present utility model is full of water in grouting pipeline, and then discontinuity injects gases at high pressure in pipeline, form High-Pressure Water, developing starching more than in pipeline.This system integrates the pressure regulating water route and gas circuit, overcomes the operating type needing to change pipeline in flushing process, and can carry out flushing operation to many Grouting Pipe simultaneously; Not only can rinse the pipeline in the shield body of front, the pipeline connected in all right back flush chassis; This system and equipment combine together, and structure is simple, coordination attractive in appearance.
Utilize this system to rinse grouting pipeline, not only greatly save washing time, and can not shutdown be caused again, can ensure that construction is worked continuously.

Fig. 1 is structural representation of the present utility model;
In figure: 1, tunneling synchronous mud injecting pump; 2, main pneumatic ball valve; 3, flow meter; 4, pneumatic ball valve is divided; 5, pressure sensor; 6, shield tail; 7, ball valve is controlled; 8, water pipe; 9, three way cock; 10, cleaning hose; 11, air pump; 12, mortar stirs chassis; 13, Grouting Pipe is divided; 14, main Grouting Pipe.
Detailed description of the invention
The utility model shield machine is carried synchronous grouting equipment to be used for a kind of new engineering method of flushing of pipeline after transformation.By this method, can save and rinse the activity duration, improve operating efficiency, ensure the continuous operation of construction operation.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1, the utility model comprises and stirs the tunneling synchronous mud injecting pump 1 that chassis is communicated with and the main Grouting Pipe 14 be communicated with described tunneling synchronous mud injecting pump 1 with mortar, described main Grouting Pipe 14 is provided with point Grouting Pipe 13 of more than two, the utility model is for four, and point Grouting Pipe 13 is serially connected with main pneumatic ball valve 2 and flow meter 3 in main Grouting Pipe 14; Described each point of Grouting Pipe 13 is all serially connected with point pneumatic ball valve 4 and pressure sensor 5, before entering point Grouting Pipe 13, be also provided with the air pump 11 be communicated with main Grouting Pipe 14, wherein, the cleaning hose 10 that air pump 11 is connected with main Grouting Pipe 14 is provided with three way cock 9, and the other end of three way cock 9 is communicated with water pipe 8.Cleaning hose 10 between three way cock 9 and main Grouting Pipe 14 is serially connected with and controls ball valve 7.
