The method is suitable for the post-grouting treatment after leakage occurs in the unilateral joint of the operation tunnel segment. Compared with the conventional grouting after the wall, the grouting has certain directivity, can effectively save the material consumption, enhance the plugging effect and reduce the economic cost.
Description
Technical Field
The invention relates to a technology for treating leakage water diseases of an operation tunnel segment, in particular to a one-way wall back grouting device for the operation tunnel segment, and belongs to the technical field of segment wall back grouting.
Background
Along with the continuous deepening of rail transit construction, the mileage of operation tunnel constantly extends, and the live time of tunnel constantly accumulates. Under the influence of geological and hydrological conditions, building activities and the like, underground tunnel segments are subjected to various diseases, wherein water leakage is one of the most common diseases.
And the slurry directly enters the outer wall of the pipe piece to form a package, and the disposal effect on the leakage water, particularly the leakage water of the joint, is obvious. The conventional grouting after the wall, without setting grouting pipe, directly grouting after drilling through the prepared hole, the slurry flowing has no directionality, and the plugging effect is achieved by the continuous accumulation of grouting materials.
Disclosure of Invention
Aiming at the defects in the prior art, the technical problem to be solved by the invention is to provide a novel light-emitting diode; realize directive property backfill grouting's one-way slip casting device of operation tunnel section of jurisdiction.
In order to solve the technical problems, the invention adopts the technical scheme that: the utility model provides an operation tunnel section of jurisdiction one-way wall post-grouting device, includes scalable slip casting bulkhead, outer silk thread connecting pipe, ball valve, change a joint, interior silk screwed pipe, screws up outer screwed pipe, outer silk thread connecting pipe one end and section of jurisdiction preformed hole threaded connection, the other end passes through the thread and connects the ball valve to be connected, and the ball valve is through changing silk articulate interior silk screwed pipe, and V type sealing washer is placed to interior silk screwed pipe inside to compress tightly through screwing up outer silk screwed pipe, make V type sealing washer and arrange outer silk thread connecting pipe, ball valve, change a joint, interior silk screwed pipe in and screw up the intraductal slip casting pipe of outer screwed pipe and form effective sealing.
Furthermore, the front part of the grouting pipe is provided with a telescopic grouting choke plug and a one-way grouting opening, and the rear part is provided with a marking.
Furthermore, when the grouting pipe is driven into the soil body through the sealing device, the telescopic grouting choke plug enables the one-way grouting port to be in a closed state, after the grouting pipe is pumped back for a certain distance, the one-way grouting port is exposed, the marked line at the tail of the grouting pipe indicates the direction of the one-way grouting port, and the grouting pipe is rotated to the leakage direction before grouting, so that one-way grouting is realized.
The invention has the beneficial effects that:
the invention relates to a one-way wall back grouting device for operating tunnel segments, which ensures that slurry has directivity by one-way wall back grouting, is suitable for the condition of water leakage of seams on one side of the segments, can effectively reduce material consumption, and improves construction efficiency and plugging effect, thereby greatly reducing cost.
In addition, the grouting pipe is driven into the outer wall of the pipe piece through a sealing device, a telescopic choke plug is arranged at the end part of the grouting pipe, a slurry outlet is in a closed state to prevent slurry from flowing in when the grouting pipe is pressed in, the slurry outlet is exposed after being pumped back for a certain distance, the slurry outlet is a single-side slurry outlet, a marking line is engraved at the other end of the grouting pipe, and the grouting port is rotated to a specified direction during grouting to realize unidirectional grouting; and before grouting, screwing the compression thread to form sealing.
Drawings
Fig. 1 is a schematic view of the one-way grouting device for the duct piece of the operating tunnel.
Detailed Description
The following description of the embodiments of the invention is provided in connection with the accompanying drawings.
As shown in figure 1, the one-way wall post-grouting device for the operation tunnel segment comprises a telescopic grouting bulkhead 1, an external thread threaded connecting pipe 3, a ball valve 4, a variable thread joint 5, an internal thread threaded pipe 6, a screwed external thread threaded pipe 7, a marking line 8, a V-shaped sealing ring 9 and a one-way grouting opening 10.
Outer silk threaded connection pipe 3 and section of jurisdiction preformed hole 2 threaded connection, external connection ball valve 4, then reduce the aperture through change silk joint 5, V type sealing washer 9 is placed to 6 inside inner thread screwed pipes, compresses tightly through screwing up outer silk screwed pipe 7, makes V type sealing washer 9 and slip casting pipe 11 form effective seal.
The grouting pipe 11 is driven into a soil body through a sealing device, the one-way grouting port 10 is in a closed state through the telescopic grouting bulkhead 1 during driving, after a drill rod is pumped back for a certain distance, the one-way grouting port 10 is exposed, the marking 8 at the tail of the grouting pipe indicates the direction of the one-way grouting port 10, the grouting pipe 11 is rotated to the leakage direction before grouting, and one-way grouting is achieved.
The application method implemented by the invention is as follows:
1. and connecting the connecting pipe, the ball valve, the variable wire joint and the sealer in the duct piece preformed hole in sequence.
2. The grouting pipe is driven into the grouting device through the grouting device, the grouting pipe rotates to a specified direction, a distance is drawn out, the bolt is screwed down to compress the sealing ring, and unidirectional grouting is achieved.
