Abstract
The present invention relates to a water-proof structure of a tunnel lining joint in shield-method construction. The water-proof structure comprises a water-retaining strip and an elastic rubber seal gasket; upper portions and lower portions of the water-retaining strip and the elastic rubber seal gasket are arranged in a joint between tunnel lining segments; joints between the tunnel lining segments include ring joints and longitudinal joints. Compared with the prior art, the water-proof structure in the invention has advantages of multiple-waterproofing function, reduced water permeability rate and the like.
Description
Technical field
The present invention relates to raceway and lay waterproof construction, particularly relate to a kind of shield tunnel liner joint waterproof construction.
Background technology
Gather because various municipal pipeline is crisscross in underground, stacked, ground civic building gets more and more, and excavation construction destroys road structure, welding, give the life of people simultaneously, work and bring inconvenience, and construction cost is more and more higher.In order to solve the contradiction of existing urban operating mechanism and construction, be born new construction technology a---trenchless technology.And in trenchless technology for long-distance pipe lay the most general technology be exactly shield construction.
Shield method be exactly within the box hat being called shield structure, keep excavation face stable while, safety is tunneled forward, at its afterbody segment assembly, then assembled one-tenth endless tube sheet is withstood with jack, utilize its counter-force, overcome the frictional resistance of front between shield machine and surrounding soil and sidewall, an often assembled endless tube sheet, width between a Lining Ring pushed ahead by jack.But the seam quantity in shield tunnel integral waterproofing area is more, the probability producing percolating water is comparatively large, and how waterproof and antiseepage is the task of top priority.
Summary of the invention
Object of the present invention is exactly providing a kind of multiple waterproof to overcome defect that above-mentioned prior art exists, reducing the shield tunnel liner joint waterproof construction of water permeation probability.
Object of the present invention can be achieved through the following technical solutions: a kind of shield tunnel liner joint waterproof construction, it is characterized in that, comprise water bar and elastic rubber gasket, described water bar and the elastic rubber gasket seam crossing between tunnel lining segment setting up and down, the seam between tunnel lining segment comprises articulating seam and longitudinal seam.
The left section of jurisdiction of described tunnel lining segment is docked in convex-concave with in the middle of the ring joint face of right section of jurisdiction.
Be provided with the boss protruded to the right in the middle of described left section of jurisdiction, in the middle of right section of jurisdiction, be provided with the groove matched with described boss.
Locating bar is provided with in the middle of the left section of jurisdiction of described tunnel lining segment and longitudinal seam face, right section of jurisdiction.
Described water bar comprises left and right, and the lap-joint of left and right is in the 45 degree of inclination angles matched.
The material of described water bar is hydro-expansive rubber.
The material of described elastic rubber gasket is ethylene propylene diene rubber.
Described tunnel lining segment top is provided with cement based penetration crystallization type water proofing paint.
Compared with prior art, the present invention adopts the method for multi-way prevention, sets up water bar and elastic rubber gasket at shield tunnel liner seam crossing, and passes through its structural design of tunnel lining contact position, effectively plays the saturating effect of waterproof, seepage control.
