An underwater section tunnel personnel evacuation and rescue channel structure and smoke control system

Abstract

The invention discloses a personnel evacuation and rescue channel structure for an underwater section tunnel and a smoke control system. A two-way stair evacuation and rescue channel structure and a slide evacuation and rescue channel structure are alternately connected in a fan-shaped escape channel; a smoke control system part in a two-way staircase is connected with the inside of the two-way stair evacuation and rescue channel structure; a smoke control system part in a slide is connected to the side wall and an entrance in the slide evacuation and rescue channel structure; an escape two-way staircase with the upper layer and the lower layer connected for escape is arranged in the fan-shaped escape channel; a lower-layer front chamber and an upper-layer front chamber are arranged between the stair of the two-way staircase and a lower-layer escape door on the lateral wall of a lower-layer lane and between the stair of the two-way staircase and an upper-layer escape door on the lateral wall of the lower-layer lane, respectively; front chamber door openings are formed in the upper-layer front chamber and the lower-layer front chamber; the upper-layer escape door on the lateral wall of an upper-layer lane and the lower-layer escape door on the lateral wall of the lower-layer lane are two-way double doors, so that personnel evacuation can become relatively efficient and safe, the escape time is greatly shortened, and personnel casualties are reduced.

Description

technical field [0001] The invention relates to the field of personnel evacuation in underwater section tunnels, in particular to a personnel evacuation and rescue channel structure and a smoke control system for underwater section double-layer tunnels, which are suitable for emergency rescue channels for personnel to escape when fire accidents occur in underwater section double-layer tunnels. Background technique [0002] With the development of modern transportation, more and more traffic tunnels have been built and put into use, and the prevention and rescue of tunnel fires have been paid more and more attention. Tunnel fire has characteristics and serious hazards that are different from ordinary fires. In a relatively narrow and closed tunnel environment, it will cause considerable damage and threat to the facilities and trapped people in it. Due to the particularity of tunnel fires, the evacuation system of traffic tunnels is particularly important in tunnel fire rescue...

AI Technical Summary

Problems solved by technology

[0004] In view of the immature form of the current escape system, there is an urgent need for a structural arrangement of personnel evacuation channels to alleviate the current problems, and try to prevent the fire smoke from invading the adjacent unfired layer tunnels, causing greater disasters

[0005] To sum up, the underwater cross-section tunnel will face greater difficulties in the design of personnel escape and evacuation due to the limited space on the upper and lower floors.
