Intelligent assembled firewall for electric power pipe gallery

Abstract

The invention belongs to the field of electric power comprehensive pipe gallery safety equipment, and particularly relates to an intelligent assembled firewall for an electric power pipe gallery. The intelligent assembled firewall comprises pull-out type fireproof assemblies, wherein the pull-out type fireproof assemblies comprise protection plates and fireproof modules. The edges of the protection plates of the prefabricated pull-out type fireproof assemblies are attached to each other to form one closed protection face, and during cable capacity increasing or replacement, only the corresponding prefabricated pull-out type fireproof assembly needs to be integrally disassembled, so that repeated forcible entry and punching of the protection plates of the firewall are avoided, the service life of the firewall is prolonged, the situation that the fireproof performance of the firewall is reduced due to secondary plugging after forcible entry is avoided, meanwhile, the construction efficiency is improved, the firewall is recovered in time, and the construction fire hazard is reduced.

Description

Technical field [0001] The present invention belongs to the field of power firewall pipe rack, particularly relates to a method of assembling firewall. Background technique [0002] Pipe Gallery, namely urban underground power, communication, gas, heating or water supply and drainage pipelines and other projects set in one of the tunnels space dedicated to laying cable or fiber optic cable and other communications cable Pipe Gallery namely electricity pipe rack "city pipe Gallery engineering and technical norms" (GB50838-2015) provisions of the gas pipeline spaces and compartments to accommodate power cables should not be less than 3.0h be noncombustible fire separation wall every 200m using fire resistance, for fire protection otherwise, the partition wall is formed of a closed cross section, collectively firewall, i.e. the inner pipe rack power to be set every 200m firewall side, the cable laying through the firewall. [0003] Firewall in the prior art are mainly two: the first...

AI Technical Summary

Problems solved by technology

[0004] At least one problem in the existing technology is that, with the development and construction of cities and towns, when the cables in the power pipe gallery are increased and replaced, the firewall surface or protective plate needs to be demolished first, and then the cables filled in A large number of fire-resistant bags or fire-proof modules above are taken out, and the cables are adjusted and backfilled. It is necessary to re-adjust the openings of the firewall surface or the protective plate to ensure airtightness, and then the capacity of the corresponding cables can be increased or replaced. The existing technology Repeated demolition or opening of the middle firewall surface or protective plate affects the service life of the firewall. The construction period is long and the workload is heavy. When the firewall cannot be restored in time, secondary risks such as fire hazards during construction will also increase.
