Abstract
The utility model discloses a kind of prefabricated pipe section mounting structures.It includes the interior steel band being embedded in section of jurisdiction and the outer steel band on the outside of interior steel band, the interior nylon sleeve that is placed with positioning hole on interior steel band and can be fixed in positioning hole, interior steel band passes through the positioning bolt concatenated in interior nylon sleeve and is fixedly mounted on section of jurisdiction, it is placed with outer concatenation hole on outer steel band and the outer nylon sleeve concatenated in hole outside can be connected and fixed, interior concatenation hole is also placed on interior steel band, there is the turnbuckle being pierced by from interior concatenation hole and outer concatenation hole in section of jurisdiction, turnbuckle is after outer nylon sleeve by outer steel band location and installation.After adopting the above structure, punch operation is not needed not only, improves waterproof performance, so that interface good seal performance, in addition it is staggeredly arranged at sealing joint, will not occur poorly sealed problem because of aging, avoid the prolonged safe handling for avoiding infiltration to improve tunnel.
Description
Technical field
The utility model relates to a kind of mounting structure of section of jurisdiction component in tunnel, specifically a kind of prefabricated pipe section installation
Structure.
Background technique
In the prior art, the tunnel in rail traffic is duct type structure, and tunnel inner wall is spliced by multi-disc section of jurisdiction,
Then conduit is installed on the inner wall in tunnel again, in the prior art due to being provided with the pass of connecting component after the completion of constructing tunnel
System is often easy to produce seepage problem, so that the behaviour in service in tunnel is affected, although later it is proposed that increasing sealing
The mounting means of circle, but it is unable to satisfy seal construction requirement only by single sealing ring, and be also easy over time
There is problem of aging.
Summary of the invention
The technical problem to be solved by the present invention is to provide one kind can be improved tunnel sealing installation capability, avoids seeping water
To improve the prefabricated pipe section mounting structure of the prolonged safe handling in tunnel.
In order to solve the above-mentioned technical problem, the prefabricated pipe section mounting structure of the utility model, including being embedded in section of jurisdiction
Interior steel band and the outer steel band on the outside of interior steel band, be placed on interior steel band positioning hole and can be fixed on it is fixed
Interior nylon sleeve in the mounting hole of position, interior steel band pass through the positioning bolt concatenated in interior nylon sleeve and are fixedly mounted on section of jurisdiction
On, it is placed with outer concatenation hole on outer steel band and the outer nylon sleeve concatenated in hole outside can be connected and fixed, on interior steel band also
It is placed with interior concatenation hole corresponding with outer concatenation hole, there is the turnbuckle being pierced by from interior concatenation hole and outer concatenation hole in section of jurisdiction,
The turnbuckle is after outer nylon sleeve by outer steel band location and installation.
Annular groove, the annular groove clamping of the interior nylon sleeve are provided in the middle part of the interior nylon sleeve and outer nylon sleeve
In the positioning hole of interior steel band, the annular groove of the outer nylon sleeve is connected in the outer concatenation hole of outer steel band.
The outside of the interior nylon sleeve has the arc seal closure being pressed on interior steel band.
The inner opposite end of the outer nylon sleeve is set as tapered surface.
After above-mentioned structure, due to being separately mounted to inside and outside nylon jacket on the inside and outside steel band and inside and outside steel band of setting
Cylinder, does not thus need punch operation not only, and in capable of being sealed in section of jurisdiction by two layers of steel band, further improves waterproof
The inside and outside nylon sleeve being arranged in performance, especially two layers of steel band makes interface good seal performance, in addition wrong at sealing joint
Arrangement is opened, will not occur poorly sealed problem because of aging, avoids the prolonged safe handling for avoiding infiltration to improve tunnel.
Detailed description of the invention
Fig. 1 is the partial profile structure of the utility model prefabricated pipe section mounting structure.
Specific embodiment
With reference to the accompanying drawings and detailed description, the prefabricated pipe section mounting structure of the utility model is made further detailed
Explanation.
As shown, the prefabricated pipe section mounting structure of the utility model, including the interior steel band 2 that is embedded in section of jurisdiction 1 and
Outer steel band 3 on the outside of interior steel band is placed with positioning hole on interior steel band 2 and can be fixed on positioning hole
Interior interior nylon sleeve 4, interior steel band 2 pass through the positioning bolt concatenated in interior nylon sleeve 4 and are fixedly mounted on section of jurisdiction 1, outside
It is placed with outer concatenation hole on steel band 3 and the outer nylon sleeve 5 concatenated in hole outside can be connected and fixed, is also arranged on interior steel band 2
It is furnished with interior concatenation hole corresponding with outer concatenation hole, especially because the splicing interface of interior steel band 2 and outer steel band 3 is staggeredly arranged, by
This arranges positioning hole and outer concatenation hole mistake, even since direct seepage problem, section of jurisdiction 1 will not occur in aging
Interior to have the turnbuckle being pierced by from interior concatenation hole and outer concatenation hole, the turnbuckle is after outer nylon sleeve 5 by outer steel
3 location and installation of band.
Further, the middle part of described interior nylon sleeve 4 and outer nylon sleeve 5 is provided with annular groove 6, interior nylon sleeve
4 annular groove is connected in the positioning hole of interior steel band 2, and the annular groove of the outer nylon sleeve 5 is connected to the outer concatenation of outer steel band 3
In hole, the outside of interior nylon sleeve 4 has the arc seal closure 7 being pressed on interior steel band 2, further improve waterproof performance and
The pressing force of arc seal closure makes sealing tighter, in addition, the inner opposite end of outer nylon sleeve 5 is set as tapered surface, the taper
Face structure designs so that its interface, which is formed, squeezes sealing effect.
