Embodiment 1

[0019] Such as Figure 1~3 As shown, a shield tunnel lining joint waterproof structure includes a water retaining strip 1 and an elastic rubber gasket 2, and the water retaining strip 1 and the elastic rubber gasket 2 are arranged up and down between the tunnel lining segments. At seams, the seams between tunnel lining segments include ring seams and longitudinal seams. The left segment 3 of the tunnel lining segment and the middle of the right segment 4 are convex-concave butt joints, that is, the middle of the left segment 3 is provided with a convex platform protruding to the right, and the middle of the right segment 4 is provided with the convex platform. There is a groove matching the platform, and a positioning rod 6 is provided in the middle of the longitudinal joint surface of the left segment 3 and the right segment 4, and the waterproof performance is enhanced through the structural design of the tunnel lining segment itself.

[0020] The water retaining strip 1 in...

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 [0001] The invention relates to a cable duct laying waterproof structure, in particular to a shield tunnel lining seam waterproof structure. Background technique [0002] Since various municipal pipelines are criss-crossing underground and densely stacked, and there are more and more municipal buildings on the ground, the excavation construction will damage the road structure and the environment, and at the same time bring a lot of inconvenience to people's life and work, and the construction cost is increasing. higher. In order to solve the contradiction between existing municipal facilities and construction, a new construction technology - trenchless technology - was born. The most common technology used for long-distance pipeline laying in non-excavation technology is the shield construction method. [0003] The shield method is to keep the excavation surface stable within the steel shell called the shield, and at the same time to safely dig forward, ass...
