Description
Technical field
The utility model is related to push bench process Tunnel Engineering, more particularly to a kind of jacking pipe joints seam construction.
Background technology
Push bench process is a kind of no-excavation construction method, and its cardinal principle is by prefabricated tube coupling to head into ground by back jack
In layer, and then the tunnel formed needed for building.In general, using prefabricated tube coupling jacking, it is molded tunnel to be longitudinally continuous
The tube coupling of certain breadth is assembled.There will be lap joint between front and rear tube coupling, the lap joint mainly has tongue-and-groove type, T-shaped socket joint
With the pattern such as F type socket joints, every kind of pattern has its feature and applicability, but generally speaking, to ensure seam waterproof performance, tradition
Various types answer abutment joint deform ability it is all poor, in the correction operation occurred unavoidably at the scene, tube coupling easily occurs
It is damaged.
In addition, general, waterproof relies primarily on the wedge-shaped rubber bar in socket, when tube coupling is installed in socket joint type joint,
The socket joint effect of front and rear tube coupling is unavoidable to cause uneven extruding and slide strips effect to wedge-shaped rubber bar, and wedge-shaped rubber bar is easily turned over
Turn even to destroy, and then influence tunnel water proofing effect.
For this reason, it may be necessary to study a kind of seam pattern so that among tube coupling socket joint and correction process, it is ensured that tunnel structure
The normal function of safety and water-proof system.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of jacking pipe joints seam construction, so that in tube coupling socket joint
With the safety and the normal function of water-proof system for ensureing tunnel structure among correction process.
The technical scheme that the utility model solution above-mentioned technical problem is taken is as follows：
A kind of jacking pipe joints seam construction of the present utility model, including longitudinal direction docking form the tube coupling in tunnel, adjacent two pipe
Section forms seam between port, it is characterized in that：Circumferentially spaced sealing gasket is correspondingly arranged on the tube coupling port of the seam both sides
Elastic sealing gasket is set in groove, each sealing gasket groove, and seam is in the closely connected seam pad of both sides tube coupling port loopful；Each tube coupling
There is circumferentially-spaced laying and longitudinally through prestressed pore passage in tube wall, hollow location lug is set in prestressed pore passage two ends
Head, each tube coupling docks to be formed behind tunnel penetrates anchor cable in each prestressed pore passage, and prestressing force is integrally applied to tunnel in tunnel end.
The beneficial effects of the utility model are, when socket joint before and after tube coupling, by positioning the effect of tenon, make tube coupling accurate
Positioning, makes front and rear ring resilience sealing gasket align, after tunnel holing through, anchor cable is penetrated in prestressed pore passage, is applied in tunnel end
Prestressing integrally tenses in tunnel, and now elastic sealing gasket stress is extruded, and reaches the effect of hermetic seal；Tube coupling jack-in process
In, allow in elastic sealing gasket in deformation range, appropriateness changes the thickness of each point position seam pad at joint face, you can reach
The purpose of correction, while not influenceing the water resistance after structure safety and tunnel shaping.
Brief description of the drawings
This specification includes following three width accompanying drawing：
Fig. 1 is a kind of assembling schematic diagram of jacking pipe joints seam construction of the utility model；
Fig. 2 is the enlarged drawing of A parts in Fig. 1；
Fig. 3 is the structure that prestressed pore passage in a kind of jacking pipe joints seam construction of the utility model and two ends position tenon
Schematic diagram.
Component name and corresponding mark are shown in figure：Tube coupling 10, sealing gasket groove 11, elastic sealing gasket 12, in advance should
Power duct 21, positioning tenon 22, seam pad 31.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Reference picture 1, Fig. 2 and Fig. 3, a kind of jacking pipe joints seam construction of the utility model, including longitudinal direction docking form tunnel
Tube coupling 10, form seam between the adjacent port of two tube coupling 10.Circumference is correspondingly arranged on the port of tube coupling 10 of the seam both sides
Elastic sealing gasket 12 is set in the sealing gasket groove 11 at interval, each sealing gasket groove 11, and seam is in both sides tube coupling A ports loopful
Closely connected seam pad 31.There is circumferentially-spaced laying and longitudinally through prestressed pore passage 21 in each tube wall of tube coupling 10, answered in pre-
The two ends of power duct 21 set hollow positioning tenon 22, and each docking of tube coupling 10 is formed behind tunnel to be penetrated in each prestressed pore passage 21
Anchor cable, prestressing force is integrally applied in tunnel end to tunnel.
Reference picture 1 and Fig. 3, when socket joint before and after tube coupling A, by positioning the effect of tenon 22, make two adjacent tube couplings 10 it
Between be accurately positioned, front and rear ring resilience sealing gasket 12 is alignd.After tunnel holing through, anchor cable is penetrated in prestressed pore passage 21,
Apply prestressing force in tunnel end integrally to tense in tunnel, now the stress of elastic sealing gasket 12 is extruded, and reaches the effect of hermetic seal.
In the jack-in process of tube coupling 10, allow in elastic sealing gasket 12 in deformation range, appropriateness changes each point position seam pad at joint face
The thickness of piece 31, you can reach the purpose of correction, while not influenceing the water resistance after structure safety and tunnel shaping.
