AI Technical Summary

Technical Problem

Urban underground transportation arteries suffer from problems such as lack of defense standards, complex system conversion, low efficiency, and insufficient planning coordination in terms of wartime protection capabilities and functional conversion, making it difficult to meet the needs of national defense security and civil defense emergency response.

Method used

Construct a hierarchical protection system for urban underground transportation arteries, combining modular design and intelligent conversion systems, including hierarchical protection, ventilation systems, water supply and drainage systems, and BIM digital management units, and achieve rapid peacetime-wartime conversion through a central control system.

Benefits of technology

This technology enables urban underground transportation arteries to maintain efficient daily operations while possessing strong wartime protection capabilities and rapid conversion capabilities. It fills the systemic technological gap in civil defense for large linear underground spaces, improves conversion efficiency and reliability, and reduces renovation costs.

Abstract

The embodiment of the present application provides a kind of urban underground traffic trunk line peace war conversion system, comprising: whole urban underground traffic trunk line, urban underground traffic trunk line refers to the underground empty entity including subway line, underground expressway or comprehensive pipe gallery;Urban underground traffic trunk line has multiple key nodes;Urban underground traffic trunk line has multiple independent protection sections, protection section refers to the length direction along ground urban underground traffic trunk line, interval where urban underground traffic trunk line is divided according to set length;Each protection section is physically disconnected and is a space unit with independent airtightness, two ends of each protection section are isolated from adjacent protection section and external environment by the blast-resistant partition wall and protection airtight door set in tunnel wall.The peace war conversion system of the present application considers the dual needs of efficient operation of urban underground traffic trunk line in peacetime and rapid protection in wartime, so that the urban underground traffic trunk line peace war conversion system considers systematicness, rapidity and reliability.
