Comprehensive pipe gallery is an important infrastructure of modern cities. Its construction provides reliable underground space for municipal pipeline construction in an intensive manner, completely solves the problem of repeated excavation of roads, and coordinates urban traffic, environment, and underground space. Development and utilization play an important role.

As the backbone channel of the pipeline, the comprehensive pipe corridor is the lifeline project of the city. Once a fire occurs inside it, it should be able to effectively control the fire within a limited range to reduce losses. According to the "Technical Code for Urban Integrated Pipe Gallery Engineering" (GB50838-2015), the natural gas pipeline cabin and the cabin containing the power cable should be separated by a non-combustible wall with a fire resistance rating of not less than 3.0h every 200m. Pipelines should be tightly sealed when they pass through fire compartments.

At present, there are two main types of firewalls commonly used in integrated pipe corridors: one is to form a firewall by building a fire-resistant package, and the fire-resistant package is fixed with a steel structure and a fire-proof board. The second type of firewall is to directly use autoclaved lime-sand bricks and other masonry materials to build the firewall, and leave a hole in the wall where the pipeline crosses and seal it with a fire-resistant bag. These two sealing methods require many on-site operations, slow construction speed, difficult quality control, relatively poor aesthetics, and the fire retardant package is not resistant to moisture and has a short service life.
