Precast splice comprehensive pipe gallery bell and spigot waterproof structure

Abstract

The invention discloses a precast splice comprehensive pipe gallery bell and spigot waterproof structure. The precast splice comprehensive pipe gallery bell and spigot waterproof structure comprises a seam composed of a pipe gallery spigot and a pipe gallery bell. At the seam, waterproof construction bodies composed of a PCM waterproof roll with the thickness of 1.5 mm to 3.0 mm, JS-211 double-component sealants, a polyethylene foam filling plate, an EPDM wedge-shaped sealing ring, a hydrophilic expansion elastic rubber body, a polyethylene foam filling plate, JS-211 double-component sealants and EPIIR self-adhesion waterproof adhesive tape with the thickness of 1.5 mm to 2.0 mm are sequentially arranged from the outer side of the seam to the inner side of the seam. Multiple waterproof guards are constructed, the outer side PCM self-adhesion polymer modified asphalt waterproof roll has the waterproof function, further can prevent plant roots from being punctured and protects the outer seam; double-component sealant cording seams achieve the waterproof and anti-seepage effects; the inner side EPIIR self-adhesion waterproof adhesive tape has the waterproof and anti-seepage functions, further achieves the effects of insect and rat damage prevention effects and mainly plays a role in protecting the inner seam; through the multiple waterproof guards, the waterproof structure is long in service life and can reach 100 years.

Description

technical field [0001] The invention relates to a prefabricated and assembled comprehensive pipe gallery, in particular to a waterproof structure for an outlet of a prefabricated and assembled comprehensive pipe gallery. Background technique [0002] The urban comprehensive pipe corridor, also known as the common ditch and the comprehensive pipe ditch, is an underground corridor built under the municipal road, which incorporates various municipal pipelines such as electricity, communication, heat, water supply and drainage, and sets up special maintenance Facilities and equipment such as mouth and feeding port. The unified construction and management of the urban comprehensive pipeline corridor saves the independent structures and earthwork excavation of the pipeline itself, which can effectively and intensively use space resources. [0003] Different forms of underground comprehensive utility corridors have different cross-sectional forms, types of pipelines accommodated, ...

AI Technical Summary

Problems solved by technology

These two methods have certain shortcomings: the construction period of pouring on-site box culvert is long, the labor intensity is high, the efficiency is low, it is greatly affected by the weather and site conditions, it is easy to cause relatively large pollution to the surrounding environment, the construction quality is also unstable, and the cost High; for the overall box culvert produced in factory, it takes a long time to form the pipe gallery, the process steps are cumbersome, the construction cost is high, and the transportation and hoisting are difficult. Especially for large box culverts, the investment in production equipment and hoisting equipment is huge. It is difficult to have production equipment and cannot manufacture

This technical solution has a certain degree of advancement, but the shortcoming is that the entire seam is filled with waterproof materials, the production is relatively cumbersome, and the cost is slightly high, so it is necessary to improve
