Problems solved by technology

[0002] At present, there are more and more tunnels constructed by the shield method in our country. Groundwater is the main factor affecting the safety of tunnels. If groundwater leaks into the tunnel, it will affect the normal operation and service life of the tunnel.
At present, shield tunnels mostly use a waterproof system. Once it fails, groundwater will leak into the tunnel. At the same time, the location of the leak cannot be accurately determined, which is not conducive to taking treatment measures.

Embodiment 1

[0012] There are 16 circular seam vertical waterproof belts perpendicular to the circular seam waterproof belts between the two parallel circular seam waterproof belts, and the circular seam vertical waterproof belts separate the two circular seam waterproof belts into 16 waterproof partitions. There are two parallel longitudinal seam waterproof belts in the shield segment, and the longitudinal seam waterproof belt and the circular seam waterproof belt vertically and seamlessly intersect. The width of the longitudinal seam waterproof belt is 24mm, and the thickness is 16mm. The width of the circular seam waterproof belt is 24mm, and the thickness is 16mm. The distance between the two longitudinal seam waterproof belts is the same as the distance between the two circular seam waterproof belts, and the position of the longitudinal seam waterproof belt corresponds to the position of the circular seam waterproof belt. The circular seam waterproof belt, the circular seam vertical w...

Embodiment 2

[0017] Between the two parallel circular seam waterproof belts, there are three circular seam vertical waterproof belts perpendicular to the circular seam waterproof belts, and the circular seam vertical waterproof belts separate the two circular seam waterproof belts into 3 waterproof partitions. There are two parallel longitudinal seam waterproof belts in the shield segment, and the longitudinal seam waterproof belt and the circular seam waterproof belt vertically and seamlessly intersect. The width of the longitudinal seam waterproof belt is 45mm, and the thickness is 22mm. The width of the circular seam waterproof belt is 45mm, and the thickness is 22mm. The distance between the two longitudinal seam waterproof belts is the same as the distance between the two circular seam waterproof belts, and the position of the longitudinal seam waterproof belt corresponds to the position of the circular seam waterproof belt. The circular seam waterproof belt, the circular seam vertica...

Abstract

The invention discloses a waterproof structure of a shield tunnel segment. The waterproof structure of the shield tunnel segment is characterized in that two parallel circular-seam waterproof zones are arranged between the inner wall and the outer wall of the shield segment; a plurality of circular-seam perpendicular waterproof zones perpendicular to the circular-seam waterproof zones are arranged between the two circular-seam waterproof zones; and the circular-seam perpendicular waterproof zones divide the two circular-seam waterproof zones into a plurality of waterproof subzones. In use, a waterproof system of the shield tunnel segment is developed into double parallel waterproof zones from one waterproof zone by adopting the the waterproof structure of the shield tunnel segment; moreover, a plurality of the circular-seam perpendicular waterproof zones perpendicular to the circular-seam waterproof zones are arranged between the two circular-seam waterproof zones, so that a plurality of the waterproof subzones are formed; the waterproof structure of the shield tunnel segment can effectively prevent underground water from entering a tunnel through longitudinal seams and circular seams; and meanwhile, when the leakage occurs to the tunnel, a leakage part can be determined correctly, which is beneficial to adopting a treatment measure.

Description

technical field [0001] The invention relates to the technical field of waterproofing of shield tunnel segments, in particular to a method for shield tunnel segments to prevent groundwater from entering the interior of the tunnel through circular joints (between rings) and longitudinal joints (between blocks). Background technique [0002] At present, there are more and more tunnels constructed by the shield method in our country. Groundwater is the main factor affecting the safety of tunnels. If groundwater leaks into the tunnel, it will affect the normal operation and service life of the tunnel. At present, shield tunnels mostly use a waterproof system. Once it fails, groundwater will leak into the tunnel. At the same time, the location of the leak cannot be accurately determined, which is not conducive to taking treatment measures. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof structure for shield tunnel segments, whic...
