The utility model relates to an underground comprehensive pipe gallery, which is a shallow-buried structure and an accessory facility for accommodating urban engineering pipelines such as electric power, communication, gas and the like, is a life line project of a city and is positioned in a person-intensive area. The utility tunnel can avoid the tradition directly to bury a great deal of drawback of pipeline to can carry out unified management and control with all kinds of pipelines. In recent years, the construction of pipe corridors in China has been vigorously developed, however, in the construction of pipe corridors in various places in the past, because of the safety risk problem caused by gas explosion and the cost problem caused by construction and operation, gas cabins are rarely brought into the construction category. And additionally, a gas pipeline is laid in the soil body, the gas pipeline is easy to be corroded by the soil body, the service life is reduced, and the negative influence of pipeline construction on repeated excavation of a road cannot be avoided.

After the gas enters the corridor, the safety problem brought by the gas must be considered. Accident data and research have shown that once a gas pipeline in a gas cabin leaks and knocks when exposed fire occurs, the structure of a pipe gallery is likely to be damaged, and further, great economic loss and even casualties are brought. And anti-explosion structures such as foamed aluminum and the like are added in the gas cabin, so that the possibility of encountering extreme gas explosion is low after the anti-explosion measures are added, the probability of gas explosion is low and the occurrence probability of the extreme gas explosion is low in the comprehensive pipe gallery constructed according to the national standard, and the operation cost such as material replacement and the like in the construction and use processes is further increased.
