Problems solved by technology

At present, the design of most pipe galleries does not consider the anti-explosion problem of the gas cabin in the pipe gallery. Therefore, how to reduce the damage of natural gas explosion to the gas cabin of the existing integrated pipe gallery has become an urgent problem to be solved.

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Such as figure 1 As shown, the present invention is a gas explosion protection device applied to the existing pipe gallery. The device includes a foam concrete hanging board 2, a steel plate 3, an angle steel 4, a brace 5 and a bolt 6. The whole device is spliced ​​by four foam concrete hanging panels, and then the spliced ​​foam concrete hanging panels are pasted on the inner surface of the gas tank of the pipe gallery to form a closed loop, and then the foam The position of the concrete siding is fixed. After the gas explosion, the explosion load is first transmitted to the surrounding foam concrete slabs. After the foam concrete slabs are compressed and destroyed to absorb a certain amount of energy, the explosion load is transmitted to the pipe gallery structure, which is equivalent to reducing the load inciden...

Abstract

The invention discloses a replaceable foam concrete hanging plate protection pipe gallery internal gas explosion device. The replaceable foam concrete hanging plate protection pipe gallery internal gas explosion device is mainly composed of foam concrete hanging plates and a fixing device. A protection device is a closed loop formed by splicing the four foam concrete hanging plates; and the fixing device is composed of angle steel, inclined struts and bolts and mainly bears the weight of foam concrete. After gas explosion happens, the foam concrete hanging plates can be compressed and broken, and therefore part of energy is absorbed, and the load peak value and energy transmitted to a pipe gallery are reduced; and meanwhile, the foam concrete hanging plates can reduce reflection loads generated by explosion of gas in the pipe gallery. After the foam concrete hanging plates absorb energy and are damaged, the hanging plates can be replaced with new hanging plates at any time, the pipe gallery does not need to be maintained and reinforced, and social manpower, material resources and financial resources are greatly saved.

Description

technical field [0001] The invention relates to the field of gas explosion protection in a pipe gallery, in particular to using a replaceable foam concrete hanging board to protect the main body of a pipe gallery gas cabin from damage caused by a gas explosion. Background technique [0002] With the rapid development of social economy, the problem of "road zipper" is becoming increasingly serious, and the unified construction of urban underground comprehensive utility corridors has become the general trend of future development. In 2016, the Ministry of Housing and Urban-Rural Development clearly required that gas pipelines must enter the corridor. Natural gas is a flammable and explosive gas. Explosion accidents caused by gas leakage will cause irreversible damage to the structure of the pipeline corridor. At present, the design of most pipe galleries does not consider the anti-explosion problem of the gas cabin in the pipe gallery. Therefore, how to reduce the damage of na...
