Problems solved by technology

In addition, in the current integrated pipe gallery, the node structure is generally a single-function node, which does not take into account the combination of nodes with multiple functions, and the ventilation openings of each compartment of the current pipe gallery are designed separately and exposed to the ground. The same is true for the openings, so that there are more ventilation openings and feeding openings exposed to the ground, which affects the traffic and also has a certain impact on the surrounding environment.

Embodiment 1

[0041] A comprehensive pipe gallery, including a main line 102 of a pipe gallery formed by splicing several boxes 101, and a box waterproof structure for waterproofing the box 101. A combined node structure is provided on the main line 102 of the pipe gallery.

[0042] Please also see Figure 1-Figure 3 , The waterproof structure of the box body is as follows. Firstly, the box body 101 includes a top plate 1 , a side wall 7 and a bottom plate 5 . Secondly, two layers of 1.5mm thick wet-laid waterproof roll material 2, 1.2mm thick root thorn resistant waterproof roll material 3 and 70mm thick C35 fine stone concrete protective layer 4 are successively laid on the top plate 1. A 50mm thick C35 fine stone concrete protective layer 4 , two layers of 1.5mm thick wet-laid waterproof coiled material 2 and a concrete cushion 6 are successively laid on the bottom plate 5 . Two layers of 1.5mm-thick wet-laid waterproof roll material 2 and 20mm-thick sintered porous brick masonry 8 (th...

Embodiment 2

[0063] In this embodiment, except for the thickness of the galvanized coating in the galvanized steel waterstop 14 and the composition of the wet-laid waterproof coil, everything else is the same as in Embodiment 1.

[0064] In this embodiment, the thickness of the galvanized coating in the galvanized steel waterstop 14 is 10 um.

[0065] The wet-laid waterproof roll material comprises a bottom isolation film layer 2-1, a material layer 2-2, an adhesive layer 2-3 located above and below the material layer 2-2, and a top isolation film layer 2-4. The material layer 2-2 includes a laminated polymer film layer, a thermoplastic elastomer layer, polyester fiber cloth and glass fiber cloth laid in sequence. The adhesive layer 2-3 is mainly made of the following components by weight: 55 parts of modified asphalt, 15 parts of citrate plasticizer, 12 parts of pentaerythritol bisphosphite antioxidant and 12 parts of aluminum hydroxide flame retardant share.

[0066] The modified aspha...

Embodiment 3

[0073] In this embodiment, except for the thickness of the galvanized coating in the galvanized steel waterstop 14 and the composition of the wet-laid waterproof coil, everything else is the same as in Embodiment 1.

[0074] In this embodiment, the thickness of the galvanized coating in the galvanized steel waterstop 14 is 9um.

[0075] The wet-laid waterproof roll material comprises a bottom isolation film layer 2-1, a material layer 2-2, an adhesive layer 2-3 and a top isolation film layer 2-4. The material layer 2-2 includes a polymer film layer containing galvanized layer, a polymer laminated film layer, a thermoplastic elastomer layer and a grid cloth layer laid in sequence. The adhesive layer 2-3 is mainly made of the following components by weight: 35 parts of modified asphalt, 12 parts of butyl naphthenate plasticizer, 8 parts of pentaerythritol bisphosphite antioxidant and aluminum hydroxide flame retardant 8 doses.

Abstract

The invention discloses a utility tunnel and a box body waterproof structure thereof and belongs to the technical field of underground utility tunnel. A box body in the utility tunnel comprises a topplate, a side wall and a bottom plate; two layers of wet lay-up waterproof rolls, a root spine resistant waterproof roll and a fine aggregate concrete protective layer are laid on the top plate in sequence; a fine aggregate concrete protective layer, two layers of wet lay-up waterproof rolls and a concrete cushion are laid on the bottom plate in sequence; two layers of wet lay-up waterproof rollsand a sintered perforated brick masonry are laid outside the side wall in sequence; adhesive layers in the wet lay-up waterproof rolls are mainly prepared by the following components of modified asphalt, plasticizer, antioxidant and flame retardant in parts by weight; the modified asphalt is prepared by the following raw materials of asphalt, rubber powder, epoxy resin, organic silicone emulsion,polyacrylate, stearic acid, aluminate ester, polyvinyl alcohol, aluminium oxide and superfine calcium carbonate in parts by weight. The utility tunnel disclosed by the invention has the advantages that the waterproof effect of the box body of the utility tunnel is improved, the service life of the box body of the utility tunnel is prolonged, projections on the ground are reduced, the traffic is improved, and the environment is beautified.

Description

technical field [0001] The invention relates to the technical field of underground comprehensive pipe gallery, in particular to a comprehensive pipe gallery and its box body waterproof structure. Background technique [0002] The comprehensive pipeline corridor is the comprehensive corridor of underground urban pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. [0003] Because the comprehensive utility gallery is an underground structure project, in order to ensure the normal operation of the pipelines in the utility gallery, the waterproof and anti-seepage performance of the boxes, interfaces, construction ...
