Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] Such as Figure 1-5 As shown, a comprehensive pipe gallery of the present invention includes several pipe cabins and a first escape passage 1 arranged in the same direction, and a one-way fire door 4 is opened on the side of the pipe cabin close to the first escape passage, so that A second escape passage 5 is provided between the one-way fire door 4 and the first escape passage 1 . Specifically, the second escape passage 5 is located in the pipeline cabin and is vertically arranged with the first escape passage 1, and the personnel in the pipeline cabin far away from the first escape passage 1 enters the room close to the first escape passage 1 through the one-way fire door 4. pipeline cabin, and enter the first escape passage 1 from the one-way fire door 4 in the pipeline cabin. The two ends of the first escape passage 1 are respectively provided with escape openings...

Abstract

The invention discloses a comprehensive pipe gallery which comprises a pipeline cabin, a first tunnel escape, an air inlet passage and an air outlet passage arranged in the same direction, wherein a one-way fireproof door is arranged on one side, close to the first tunnel escape, of the pipeline cabin; a second tunnel escape is arranged between the one-way fireproof door and the first tunnel escape; an air inlet device is arranged between the air inlet passage and the pipeline cabin; and an air outlet device is arranged between the pipeline cabin and the air outlet passage. According to the invention, the first tunnel escape, the air inlet passage and the air outlet passage are arranged, the one-way fireproof door is arranged on one side, close to the first tunnel escape, of the pipeline cabin, and the second tunnel escape is arranged between the one-way fireproof door and the first tunnel escape, so that an escape safety system with whole-line arranged escape passages is formed, and the ventilation requirement that an escape exit and a ventilation opening penetrating through the ground can be arranged across a longer distance for an escape and natural gas pipeline cabin of an underground comprehensive pipe gallery is met.

Description

technical field [0001] The invention relates to the technical field of pipe gallery, in particular to a comprehensive pipe gallery. Background technique [0002] The comprehensive pipe gallery is a hot spot today and an inevitable demand for urban development. The scope of comprehensive pipe corridors includes various municipal public pipelines such as water supply, reclaimed water, rainwater, sewage, electricity, communication, heat and natural gas, and the Ministry of Construction requires the construction of road sections with comprehensive pipe corridors. According to the current comprehensive pipe corridor specification: natural gas and electric cable cabins should have a fire compartment every 200m; the distance between escape openings in natural gas cabins and electric cable cabins should not be greater than 200m, and the distance between escape openings in thermal cabins should not be greater than 400m. When the heat medium is steam The distance between escape exits...
