Ventilation and escape structure for underground pipe gallery

Abstract

The invention relates to a ventilation and escape structure for an underground pipe gallery, which belongs to the technical field of underground buildings, and includes an underground pipe gallery wall, an inspection cabin, an explosion-proof layer, an inspection lane, an inspection vehicle, an electric rising floor, a high-strength steel strand, and a crane port. Ventilation cabin, large exhaust ventilator, steel bracket, etc. The underground pipe gallery is divided into upper, middle and lower floors. There is an inspection cabin in the middle of the upper floor, ventilation cabins are installed on the left and right sides, and an explosion-proof layer is installed on the inner wall of the inspection cabin. For the driveway, a crane port is set in each safety section, and a cover plate is provided above the crane port, and an electric rising floor is installed at the corresponding place below each crane port, and high-strength steel strands are used to connect with the crane port, and the maintenance lane at the electric rising floor and its It is connected as a whole and can be separated and disassembled from other parts of the maintenance lane. The invention has the advantages of combining the functions of ventilation and escape, meeting the safety requirements, and at the same time reducing the engineering cost to the greatest extent, and has strong practicability.

Description

technical field [0001] The invention belongs to the technical field of underground buildings, in particular to a ventilation and escape structure for an underground pipe corridor. Background technique [0002] 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 ...

AI Technical Summary

Problems solved by technology

[0003] 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, which deviated from the original intention of the comprehensive utility corridor to improve urban roads and landscapes, and the social impact was relatively poor
