Abstract
A backfill grouting system of a shield tunneling machine comprises four groups of grouting pipes arranged in shield tail grouting casings, wherein each group consists of three grouting pipes; a manual valve is installed at an inlet of each grouting pipe; and a check valve is installed at an outlet of each grouting pipe. The problem of shutdown delay caused by the low usage rate and pipeline blockage is solved. The system has the characteristics of lower cost and easiness in refit; a plurality of intervals can be used, the grouting efficiency can be improved during usage, and spare pipelines can be changed timely during the emergent pipeline blockage, so that dredging of blocked pipelines can be conducted while propulsion, and the shutdown time is saved.
Description
Technical field
The utility model relates to a kind of shield machine grouting behind shaft or drift lining system.
Background technology
In shield driving process, filling system is often because the deposition of slurries in pipeline causes pipeline blockage, particularly after grouting behind shaft or drift lining pipeline blockage, cannot disassemble, dredge comparatively time-consuming, effort, as 1 grouting pipeline only after wall, after obstruction, cannot carry out normal shield driving, serious restriction construction is produced, and a slight grouting pipeline is said the shut-down that causes whole interval.Therefore former machine configuration cannot meet the requirement of shield structure normal construction.
Utility model content
Its object of the utility model is just to provide a kind of shield machine grouting behind shaft or drift lining system, has solved the problem that utilization rate is low, pipeline blockage causes shutdown to incur loss through delay.Have cost lower, the easy feature of repacking, and can use many intervals, can not only improve slip casting efficiency during use, and can when pipeline promptly stops up, change in time spare duct, can propelling limit, limit dredge blockage pipeline, saved downtime.
The technical scheme that realizes above-mentioned purpose and take, comprises 4 groups of Grouting Pipe that are located in grouting at the tail of the shield machine shell, and described Grouting Pipe is provided with three, and manual valve is installed in every Grouting Pipe entrance, and one way valve is installed in exit.
Compared with prior art the utlity model has following advantage.
1, native system will improve the utilization rate of grouting behind shaft or drift lining pipeline greatly, saves the time of shutting down repair and maintenance, increases the operating efficiency of shield machine;
2, once transformation, can be used a plurality of intervals;
3, cost is low, and production process is simple, easy to operate, and applicability is stronger.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure schematic front view.
Fig. 2 is for A in this device is to side diagram.
The specific embodiment
This device comprises 4 groups of Grouting Pipe 2 that are located in grouting at the tail of the shield machine shell 1, and as shown in Figure 1, 2, described Grouting Pipe 2 is provided with three, and manual valve 3 is installed in every Grouting Pipe 2 entrance, and one way valve 4 is installed in exit.
Described Grouting Pipe 2 is diameter 50mm seamless steel pipe.
This device is multi-pipeline formula filling system after a kind of wall of being transformed on the basis of original grouting behind shaft or drift lining system, and being increases grouting behind shaft or drift lining pipeline quantity, improves utilization rate, and the shutdown that prevention pipeline blockage causes is incured loss through delay.Remove independent pipeline and the fluid-control valve of former grouting behind shaft or drift lining, reinstall, implant three 50mm seamless steel pipes and make grouting pipeline (use, two standby), and in grouting pipeline entrance, manual valve is installed, be convenient to independent control.
Before shield machine assembling, in repair and maintenance place, 4 groups of slip casting shells of shield tail are all cut open, 3 finished (length is accurately located and mantle fiber) grouting pipelines are mounted in same slip casting shell, and again make slip casting shell according to the size of built-in pipeline, and welding, other slip casting shell transformation, repeats operation according to the method described above.
Claims (2)
1. a shield machine grouting behind shaft or drift lining system, comprise 4 groups of Grouting Pipe (2) that are located in grouting at the tail of the shield machine shell (1), it is characterized in that, described Grouting Pipe (2) is provided with three, manual valve (3) is installed in every Grouting Pipe (2) entrance, and one way valve (4) is installed in exit.
2. a kind of shield machine grouting behind shaft or drift lining system according to claim 1, is characterized in that, described Grouting Pipe (2) is diameter 50mm seamless steel pipe.
