Description

Technical Field

[0001] This utility model relates to the field of polymer materials, specifically a waterproof layer structure for the expansion joint of an underground integrated pipe gallery roof. Background Technology

[0002] Underground utility tunnels refer to structures and ancillary facilities built below the city surface for the centralized laying of two or more public utility pipelines. The main pipelines they accommodate include power, communication, radio and television, water supply, drainage, heating, gas, fire protection pipelines, traffic signal lines, and emergency optical cables. By incorporating the pipelines into the underground space, the problem of frequent road excavation due to pipeline construction or maintenance can be effectively avoided.

[0003] The prior art patent document CN206090644U discloses a waterproof layer structure for expansion joints in underground roof slabs. This waterproof layer consists of two layers, which enhances the waterproofing effect. If the first waterproof layer is damaged, the second layer can still provide waterproofing, increasing practicality. The first layer of the two waterproof layers is composed of SBS polyester reinforcing material and a root-penetration resistant waterproof membrane, while the second layer is also composed of SBS polyester reinforcing material. By adopting the above technical solution, the first waterproof layer is composed of SBS polyester reinforcing material and a root-penetration resistant waterproof membrane. Because SBS polyester reinforcing material has high toughness and elasticity, it is not easily damaged. Furthermore, SBS polyester reinforcing material can be used in a temperature range of -25 degrees Celsius to 100 degrees Celsius, allowing it to be used in harsh environments, thus increasing practicality. The second waterproof layer is... The material is made of SBS polyester, allowing the second waterproof layer to provide waterproofing after the first waterproof layer is damaged, thus increasing its practicality. Several protrusions are provided at the extension of the rubber waterstop, increasing the friction between the waterstop and the reinforced concrete base structure, resulting in better positioning and further enhancing practicality. A PE foam rod is placed at the lower end of the waterproof layer, corresponding to the upper end of the expansion joint. Since the expansion joint can deform due to temperature changes and other factors, potentially causing the waterproof layer to break, the PE foam rod acts as a buffer, preventing breakage and increasing practicality. This design offers practicality, better waterproofing, and cost savings in production.

[0004] However, in the existing technology CN206090644U patent, the waterproof layer structure of the underground roof expansion joint has poor buffer splicing and waterproof absorption capacity. As a result, in the actual use of the waterproof layer structure of the underground roof expansion joint, it is not possible to buffer splicing the expansion joint waterproof layer structure as needed, and it is not convenient to waterproof and absorb water from the expansion joint waterproof layer structure, which affects the waterproof effect of the underground roof expansion joint waterproof layer structure.

By using the polyvinyl alcohol fiber board, polyester microfiber board, and natural cotton fiber board, the water absorption effect of the waterproof layer structure of the expansion joint of the underground integrated pipe gallery roof is improved. Compared with the prior art, the beneficial effects of this utility model are: 1.
