Problems solved by technology

[0003] The traditional pipe gallery generally considers the safety of the gas pipeline and does not include the gas pipeline into the pipe gallery, and only buries the gas pipeline separately in the soil, so that the gas pipeline has no space protection and is easily damaged by soil corrosion, and the road excavation workload is large , and it is not convenient for unified management and maintenance of underground pipelines

Embodiment 1

[0023] Such as Figure 1-2 As shown, this embodiment proposes an explosion-proof integrated pipe gallery through the underground rainwater storage tank 2 for explosion venting. For example, in the partition of every 200 meters in the comprehensive pipe gallery, the inner section of the rainwater storage tank 2 is 270cm×180cm, and the bottom of the wall between it and the gas pipe trench 1 is reserved for an opening every 2 meters along the longitudinal direction , The opening size is 33cm×33cm. The internal cross-sectional size of the gas pipe ditch 1 in the middle of the pipe gallery is 270cm×150cm, and it is spliced ​​by prefabricated explosion-proof reinforced concrete panels. The gas pipe ditch 1 is divided into upper and lower parts by a partition. A venting vent is evenly arranged in the longitudinal direction of the comprehensive pipe gallery. The size of the blast vent is 50.5cm×50.5cm. Each blast vent is connected with a blast vent plate 3 of about 50cm×50cm combined...

Abstract

The invention discloses an explosion-proof utility tunnel. The utility tunnel comprises a gas pipe trench, a rainwater storage tank, a vent panel, water-proof rubber rings and an integrated pipe tank, wherein the gas pipe trench is arranged between the rainwater storage tank and the integrated pipe tank, and divided into an upper part and a lower part by a baffle, and a gas pipe is located on the upper part of the gas pipe trench; a wall that is shared by the gas pipe trench and the rainwater storage tank downwards extends to the bottom of the utility tunnel body, and the bottom of the wall is longitudinally and evenly provided with a row of openings along the utility tunnel; the baffle of the gas pipe trench is longitudinally and evenly provided with a row of explosion vents along the utility tunnel; and the vent panel is combined with the water-proof rubber rings for sealing the explosion vents. In case of explosion of the gas pipe trench, explosion pressure can be reduced rapidly due to damage of the vent panel and the damping and energy absorption of rainwater in the rainwater storage tank; and after explosion, professionals enter the utility tunnel and repair the part, where accidents occurred, of the gas pipe trench. Gas pipelines can be included in the explosion-proof utility tunnel with high explosion-proof capability, and the safety of the gas pipelines entering the utility tunnel is improved.

Description

technical field [0001] The invention relates to the technical field of comprehensive pipe gallery, in particular to an explosion-proof comprehensive pipe gallery for explosion venting through an underground rainwater storage tank. technical background [0002] At present, most of the common comprehensive pipe galleries in China include power, information, water supply, heat and other pipelines, and there are only a few comprehensive pipe galleries that include gas pipelines. In the past, due to concerns about the fire safety of gas pipelines, it was often not considered to be included in the comprehensive pipe gallery. However, gas pipelines are an important part of urban infrastructure, facilities that ensure the normal operation of people's lives and urban functions, and are lifeline projects. . Moreover, the gas pipeline is laid in the comprehensive pipeline gallery, which can improve the operating environment of the pipeline and improve the daily inspection and maintena...
