Embodiment Construction

[0030] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and cannot be interpreted as limiting the protection scope of the application. The above application content makes some non-essential improvements and adjustments to this application.

[0031] combine Figure 1 to Figure 4 As shown in the figure, a tunnel thermal insulation integrated drainage system includes a self-adhesive waterproof board 1 and a circular blind pipe 2 arranged on the tunnel arch wall, and a vertical permeable pipe 3 arranged in the tunnel invert, and the design The side ditches 4 on both sides of the tunnel invert and the central drainage pipe 5 in the filling layer of the tunnel invert are all prior art and will not be described in detail here. The improvement of the present invention lies in that: between the self-adhesive w...

Abstract

The invention discloses a tunnel auxiliary heat type heat preservation integrated drainage system. The system is provided with a nano-vacuum insulation board between a self-adhesive waterproof board and an annular blind pipe and between the initial support of the tunnel inverted arch and a secondary lining, the side ditch of the system comprises a side ditch body and a cover plate, wherein electric tracing bands are laid at the bottom of the side ditch body, a buffer layer wraps the surface of the electric tracing bands, the buffer layer just fills the bottom of the side ditch body completely,a waterproof layer is laid on the upper surface of the buffer layer, and the two sides of the waterproof layer extend to be in sealed connection with the side wall of the side ditch body. The systemhas the advantages that a side ditch structure has a heat-laying function, and the phenomena such as side ditch icing, frost heaving and ice plug can be effectively avoided; the electric tracing bandsare wrapped by the buffer layer, so that the safety and the anti-extrusion performance are improved; the waterproof layer is arranged above the buffer layer and can effectively block the flowing water to soak the electric tracing bands, the working stability and the service life of the electric tracing bands are improved, and hot air generated under the waterproof layer penetrates through the waterproof layer to be discharged, so that expansion and damage are avoided.

Description

technical field [0001] The invention relates to the technical field of tunnel drainage, in particular to an integrated drainage system for tunnel heating with thermal insulation. Background technique [0002] Tunnels built in northern my country and high-altitude cold areas, when winter comes, due to low temperature, the water flow is easy to freeze and block the drainage pipes, which will cause ice on the arch of the tunnel, ice on the side wall, ice on the network cable equipment in the cave, and surrounding rocks. Frost heaving, lining swelling, ice cones at the bottom of the tunnel, ice plugs in water ditches, frozen lines, etc., not only cause damage to the tunnel lining structure, but also cause boundary violations, endangering driving safety. [0003] However, the thermal insulation and antifreeze performance of the traditional tunnel drainage system is average. Therefore, we need to optimize the structure of the tunnel drainage system to improve its thermal insulation...
