Description

Technical Field

[0001] The utility model relates to the technical field of tunnel annular drainage pipes, in particular to a tunnel annular drainage pipe provided with a strip insulation layer. Background Art

[0002] Tunnels in cold regions often suffer from poor drainage due to freezing of the drainage system behind the lining wall, especially the freezing of the annular drainage pipe, which can induce various tunnel freezing damages. There are two existing methods for preventing the freezing of the annular drainage pipe in tunnels: one is to set an insulation layer on the outer surface of the tunnel lining; the other is to set an insulation layer on the back of the tunnel lining wall.

[0003] According to Chinese patent publication number CN201310381, a tunnel annular drainage pipe provided with a strip insulation layer is provided, which relates to the technical field of tunnel annular drainage pipes. It includes an annular drainage pipe behind the lining wall and two annular drainage pipes under the road surface connected to the two ends of the annular drainage pipe behind the lining wall. The annular drainage pipe behind the lining wall is a permeable pipe. The two annular drainage pipes under the road surface are arranged horizontally and connect the annular drainage pipe behind the lining wall and the central drainage pipe located in the center of the tunnel. The annular drainage pipe behind the lining wall is provided with a strip insulation layer on one side close to the concrete lining. The strip insulation layer includes two layers of waterproof boards and a thermal insulation material layer arranged between the two layers of waterproof boards. The utility model has a simple structure, low cost, short drainage flow distance, and because the thermal insulation material is not soaked by the formation seepage, the pipe will not be blocked by ice, so it can effectively and quickly remove the formation seepage behind the tunnel lining wall.
