Background technique

With the continuous advancement of contemporary science and technology, the existence of objective problems such as the functional requirements of urban living environment, the balance between energy shortage and environmental protection, and the expansion of new areas for the overall coordinated development of old city cultural protection areas and new urban areas, etc., all require Urban infrastructure is on the road to technological integration. According to the regulations, the integrated pipe gallery must be equipped with many nodes such as ventilation openings, personnel entrances and exits, pipeline outlets, and feeding ports. At the same time, from the perspective of ensuring the safety of inspection and maintenance construction personnel in the comprehensive escape port.

It can be seen that various nodes are arranged at intervals without reasonable unified coordination, which makes various maintenance shafts, air shafts, entrances and exits and other facilities exposed to the ground densely distributed along the comprehensive pipe corridor. The urban landscape, city appearance environment, etc. caused a great impact, and then deviated from the original intention of the comprehensive utility corridor to improve urban roads and landscapes, and the social impact was relatively poor.

Therefore, how to reasonably unify and coordinate the above nodes, especially the ventilation openings and escape openings, is a difficult problem in the design of the underground comprehensive pipe gallery.

Further, the size of the large exhaust ventilator (3-1) set in the ventilation bin (3) accounts for 1/2 to 1/3 of the size of the overall exhaust port (3-3). Personnel can escape from the gap in the exhaust port (3-3).

Furthermore, the metal louvers (3-4) at the exhaust outlet (3-3) in the upper ventilation cabin (3) of the underground pipe gallery are higher than the ground (11).

Beneficial effects of the present invention:

The advantages and effects of the present invention are that it not only has the function of ventilation, but also has the function of escaping from a crane. At the same time, the two are combined together to coordinate the setting, which improves the impact of the comprehensive pipe gallery nodes on urban roads and landscapes, and reduces the construction cost. It will also further reduce the impact of each node of the comprehensive pipe corridor on the urban landscape, city appearance and environment, and then reflect the original intention of the comprehensive pipe corridor to improve urban roads and landscapes. It has good social effects and strong practicability. The invention proposes the concept of a safety section. Under the condition of ensuring the safety of use, the ventilation openings and the crane openings are arranged alternately on the same plane. The crane openings can play the role of ventilation, and the ventilation openings can also play the role of escape routes. (in case of emergency), this not only meets the requirements of the pipe gallery specification, but also maximizes the use of the pipe gallery outlet, thereby reducing construction difficulty and reducing project investment, making it convenient for pipeline installation and operation management after the pipe gallery is completed .
