Abstract
The present invention relates to a kind of unidirectional grouting behind shaft or drift lining devices in operation tunnel section of jurisdiction, outer silk screw nipple one end is threadedly coupled with section of jurisdiction preformed hole, the other end is connected by screw thread access valve, ball valve connects internal thread screwed pipe by thread-changing joint, V-shaped seal ring is placed inside internal thread screwed pipe, and compressed by tightening outer silk screwed pipe, so that V-shaped seal ring is formed effective sealing with Grouting Pipe, avoids grout；Grouting Pipe is squeezed by sealing device to section of jurisdiction outer wall, its end be equipped with it is scalable silently, grout outlet, which is in closed state, when indentation prevents muddy water from flowing into, grout outlet exposes after pumpback certain distance, grout outlet is unilateral pulp, it is carved with graticule in the Grouting Pipe other end, when slip casting rotates grouting port to assigned direction, realizes unidirectional grout.The present invention is suitable for operation tunnel section of jurisdiction unilateral side seam and the grouting behind shaft or drift lining disposition after leakage occurs.Compared to conventional grouting behind shaft or drift lining, injection slurries have certain directive property, the effectively save material utilization amount of energy to enhance plugging effect, reduce economic cost.
Description
Technical field
The present invention relates to a kind of operation tunnel section of jurisdiction water leakage defect disposal technology, especially a kind of operation tunnel section of jurisdiction is single
To grouting behind shaft or drift lining device, belong to grouting be- hind segment technical field.
Background technology
With deepening constantly for urban rail transit construction, the mileage of operation tunnel constantly extends, and the usage time in tunnel is continuous
Accumulation.It being influenced by geological hydrology condition, construction activity etc. are a series of, there are various diseases in subterranean tunnel section of jurisdiction, wherein
Percolating water is one of most common disease.
Grouting behind shaft or drift lining is directly entered section of jurisdiction outer wall by reserved injected hole slip casting, slurries, forms package, especially to percolating water
It is that the disposition of seam percolating water is with obvious effects.Conventional grouting behind shaft or drift lining, does not set Grouting Pipe, is directly in the milk after getting through preformed hole, slurries
Non-directive is flowed, plugging effect is reached by the continuous accumulation of injecting paste material.
Invention content
Defect present in for the above-mentioned prior art, technical problem to be solved by the invention is to provide one kind；It realizes
The unidirectional grouting behind shaft or drift lining device in operation tunnel section of jurisdiction of directive property grouting behind shaft or drift lining.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：After a kind of unidirectional wall in operation tunnel section of jurisdiction
Grouting device, including scalable slip casting silently, outer silk screw nipple, ball valve, thread-changing joint, internal thread screwed pipe, tighten outer spiral shell
Line pipe, described outer silk screw nipple one end are threadedly coupled with section of jurisdiction preformed hole, and the other end is connected by screw thread access valve, ball valve
Internal thread screwed pipe is connected by thread-changing joint, places V-shaped seal ring inside internal thread screwed pipe, and by tightening outer silk screwed pipe pressure
Tightly, make V-shaped seal ring and be placed in outer silk screw nipple, ball valve, thread-changing joint, internal thread screwed pipe and tighten in male-pipe
Grouting Pipe forms effective sealing.
Further, the Grouting Pipe front portion is equipped with scalable slip casting silently with unidirectional grout mouth, and rear portion is equipped with graticule.
Further, when Grouting Pipe squeezes into the soil body by sealing device, the scalable slip casting silently makes unidirectional grout mouth
After closed state, pumpback certain distance, the unidirectional grout mouth exposes, and the graticule of Grouting Pipe tail portion indicates unidirectional grout mouth
Direction rotates Grouting Pipe to direction is leaked, realizes unidirectional grout before slip casting.
The beneficial effects of the invention are as follows：
The present invention is the unidirectional grouting behind shaft or drift lining device in operation tunnel section of jurisdiction, and unidirectional grouting behind shaft or drift lining makes slurries have directive property, is suitable for
The case where section of jurisdiction unilateral side seam percolating water, can effectively reduce material consumption, improve construction efficiency and plugging effect, to significantly
Reduce cost.
In addition, Grouting Pipe is squeezed by sealing device to section of jurisdiction outer wall, end be equipped with it is scalable silently, pulp when indentation
Mouth prevents muddy water from flowing into closed state, and grout outlet exposes after pumpback certain distance, and grout outlet is unilateral pulp, in Grouting Pipe
The other end is carved with graticule, and when slip casting rotates grouting port to assigned direction, realizes unidirectional grout；Collet threaded shape is screwed before slip casting
At sealing.
Description of the drawings
Fig. 1 is the unidirectional grouting behind shaft or drift lining schematic device in operation tunnel section of jurisdiction of the present invention.
Specific implementation mode
The implementation of the present invention is described in further detail below in conjunction with description of the drawings.
As shown in Figure 1, a kind of unidirectional grouting behind shaft or drift lining device in operation tunnel section of jurisdiction, including scalable slip casting silently 1, outer silk spiral shell
Line connecting tube 3, thread-changing joint 5, internal thread screwed pipe 6, tightens outer silk screwed pipe 7, graticule 8, V-shaped seal ring 9, unidirectional note at ball valve 4
Starch mouth 10.
Outer silk screw nipple 3 is threadedly coupled with section of jurisdiction preformed hole 2, then external connection ball valve 4 passes through thread-changing joint 5
V-shaped seal ring 9 is placed in reduced bore, the inside of internal thread screwed pipe 6, is compressed by tightening outer silk screwed pipe 7, make V-shaped seal ring 9 with
Grouting Pipe 11 forms effective sealing.
Grouting Pipe 11 squeezes into the soil body by sealing device, when squeezing into scalable slip casting silently 1 unidirectional grout mouth 10 is made to be in
Closed state, after pumpback certain distance drilling rod, unidirectional grout mouth 10 exposes, and the graticule 8 of Grouting Pipe tail portion indicates unidirectional grout mouth
10 directions rotate Grouting Pipe 11 to leakage direction, realize unidirectional grout before slip casting.
The application method that the present invention is implemented is as follows：
1, connecting tube, ball valve, thread-changing joint, sealer are connected in turn in the preformed hole of section of jurisdiction.
2, Grouting Pipe is squeezed by above-mentioned apparatus, rotates to assigned direction, takes out a distance afterwards, tighten bolt presses sealing
Circle realizes unidirectional grout.
3, it after slip casting, loosers a bolt, extracts out outside Grouting Pipe to ball valve, close ball valve, remove external device (ED).
