Abstract
The utility model relates to a water-proof structure for cable tunnel shield construction. The water-proof structure comprises a water retaining strip and an elastic rubber sealing gasket, wherein the water retaining strip and the elastic rubber sealing gasket are vertically arranged at a joint between tunnel lining segments; and the joint between the tunnel lining segments comprises a circumferential joint and a longitudinal joint. Compared with the prior art, the water-proof structure has the advantages of multiple water-proof function, reduced probability of water permeability and the like.
Description
Technical field
The utility model relates to raceway and lays waterproof construction, relates in particular to a kind of cable tunnel shield-tunneling construction waterproof construction.
Background technology
Because various municipal pipelines are underground crisscross, stacked gathering, ground civic building is more and more, and excavation construction destroys road structure, destroys environment, bring inconvenience for simultaneously people's life, work, and construction cost is more and more higher.In order to solve the contradiction of existing urban operating mechanism and construction, a new construction technology---trenchless technology has been born.And be used for the most general technology of long-distance pipe laying in the trenchless technology is exactly shield construction.
Shield method be exactly within the box hat that is called the shield structure, keep the excavation face stable in, safety is driving forward, at its afterbody segment assembly, withstand assembled one-tenth endless tube sheet with jack then, utilize its counter-force, overcome the front between shield machine and surrounding soil and the frictional resistance of sidewall, every assembly unit one endless tube sheet, jack is pushed ahead a lining cutting interannular width.But the seam quantity in the shield tunnel integral waterproofing area is more, and the probability that produces percolating water is bigger, and how waterproof and antiseepage is the task of top priority.
Summary of the invention
The purpose of this utility model is exactly the cable tunnel shield-tunneling construction waterproof construction that provides a kind of multiple waterproof for the defective that overcomes above-mentioned prior art existence, reduces the water permeation probability.
The purpose of this utility model can be achieved through the following technical solutions: a kind of cable tunnel shield-tunneling construction waterproof construction, it is characterized in that, comprise water bar and elastic rubber gasket, described water bar and the seam crossing of elastic rubber gasket upper and lower settings between tunnel lining segment, the seam between the tunnel lining segment comprise articulating seam and longitudinal seam.
The left section of jurisdiction of described tunnel lining segment is convex-concave with ring joint face centre, right section of jurisdiction and docks.
Be provided with the boss that protrudes to the right in the middle of the described left section of jurisdiction, be provided with the groove that is complementary with described boss in the middle of the right section of jurisdiction.
Be provided with locating bar in the middle of the left section of jurisdiction of described tunnel lining segment and the right section of jurisdiction longitudinal seam face.
Described water bar comprises left sheet and right sheet, and the lap-joint of left sheet and right sheet is the 45 degree inclination angles that are complementary.
The material of described water bar is a hydro-expansive rubber.
The material of described elastic rubber gasket is an ethylene propylene diene rubber.
Described tunnel lining segment top is provided with the cement based penetration crystallization type water proofing paint layer.
Compared with prior art, the utility model adopts the method for multi-way prevention, sets up water bar and elastic rubber gasket at the shield tunnel liner seam crossing, and designs by the self structure of tunnel lining contact position, plays the saturating effect of waterproof, seepage control effectively.
