Embodiment Construction

[0016] The features of the present invention and other related features will be further described in detail below through embodiments in conjunction with the accompanying drawings, so as to facilitate the understanding of those skilled in the industry:

[0017] As shown in Figure 1-2, the numbers 1-13 respectively indicate: new air shaft 1, green space 2, piston air shaft 3, subway entrance 4, green fence 5, vent 6, metal mesh cover 7, air shaft height 8, open air Well 9, sump 10, underground air duct 11, exhaust air shaft 12, piston air shaft 13.

[0018] This embodiment relates to an underground subway station, including the underground air duct 11 of the subway and the subway entrance and exit 4. In this working condition, there are eight open air shafts 9 in the green space 2, and each 4 is set in a group, including a new air shaft. 1. One exhaust air shaft 12 and two piston air shafts 3, as shown in Figure 2. The opening of the vent 6 of the open air shaft 9 is upward and is ...

Abstract

The present invention belongs to the field of tunnel technology, in the concrete, it relates to an open ultra-low air shaft arrangement mode for underground air duct. Said invention adopts top portion ventilation mode to lower height of air shaft, and utilizes the limitation of spaced distance between air shafts and arrangement of air shaft opening surface and peripheral green fence to meet fire protection requirement of underground railway interior, at same time can meet the requirement for urban landscape.

Description

Technical field [0001] The present invention relates to tunnels, in particular to an open ultra-low air shaft setting method for underground air ducts. Background technique [0002] The conventionally adopted high wind shafts are often difficult to implement due to the location. For example, an underground station has 8 wind shafts under normal working conditions, and usually every 4 is set in a group. Due to the functional requirements of new air shafts, exhaust air shafts, and piston air shafts, they must be spaced apart in height or plane, so when combined, the air shafts are as high as 15-20m. If it is combined with the ground building group, it can still be handled well, but when the numerous ventilation shafts are located in the open square. Summary of the invention [0003] The purpose of the present invention is to provide an open ultra-low air shaft setting method for underground air ducts based on the above-mentioned shortcomings of the prior art. The setting method ad...
