Multifunctional urban underground space fire-resistant structure

Abstract

The invention discloses a multifunctional urban underground space fire-resistant structure. The multifunctional urban underground space fire-resistant structure comprises a two-way six-lane urban tunnel and a comprehensive pipe gallery arranged on one side of the urban tunnel side by side, the comprehensive pipe gallery and the urban tunnel do not communicate with each other, the section of the comprehensive pipe gallery adopts a two-layer three-cabin form, the urban tunnel is a double-hole tunnel and a one-way three-lane scale, the comprehensive pipe gallery and the urban tunnel are of a rectangular closed frame structure, and a fireproof coating with a certain thickness is applied to the interior of a main body structure. The urban tunnel and the comprehensive pipe gallery are integrally designed and constructed, the rectangular closed frame structure is simple in form, the utilization rate of the internal space of the structure can be effectively increased, the adverse effects of multiple times of construction on adjacent buildings and the surrounding environment are reduced, and the fire-resistant safety performance of the underground overall structure can be guaranteed when a fire disaster happens.

Description

Technical field[0001]The present invention relates to the field of urban underground engineering traffic design, and in particular, a multi-functional city underground space refractory structure is integrated in a collection of urban tunnels and integrated gallery.Background technique[0002]With the continuous improvement of the rapid development of my country's economy, there are many problems in the shortage of land resources, road traffic congestion, insufficient infrastructure, and urban development faces increasing space constraints and challenges. Therefore, urban development has extended the new choice for urban development, and the development and utilization of urban space has become a new trend in the future development of my country.[0003]The urban underground space has mainly available urban underground roads, rail transit, underground roadway, underground commercial streets and integrated gallery, etc., my country's comprehensive distribution scale is increasingly expand...

AI Technical Summary

Problems solved by technology

[0003] The utilization forms of urban underground space mainly include urban underground roads, rail transit, underground walkways, underground commercial streets and comprehensive pipe corridors, etc., and the construction scale of my country's comprehensive pipe corridors is expanding day by day, while the construction of traditional urban underground projects in my country In the process, separate single design and construction are generally adopted. This method is not conducive to the effective and intensive use of urban underground resources and the saving of total construction investment. At the same time, separate construction will affect the adjacent buildings (structures) and The surrounding environment has caused multiple adverse effects, and the social and economic benefits are relatively low

At the same time, due to the narrow and long structure of the urban underground structure and its relatively closed space, once a fire breaks out, the fire will be violent and the temperature of the smoke will rise rapidly, which will pose a serious threat to the safety of its own structure and its adjacent structures.
