AI Technical Summary

Technical Problem

In the event of a mudslide or water inrush in a tunnel, the existing escape system is unable to effectively cope with large volumes of water and high-speed inrushes, making it impossible for construction workers to evacuate in time. Furthermore, the mechanical equipment is unstable and easily washed away, and the existing escape equipment lacks emergency supplies and communication facilities.

Method used

Escape platforms and transfer mechanisms are set up inside the tunnel. Construction workers are quickly transferred to escape cabins on the secondary lining trolley using climbing devices and transfer mechanisms. The escape cabins are equipped with communication equipment and emergency supplies, and alarm devices are used to promptly transmit dangerous situations.

Benefits of technology

It enabled the rapid transfer and evacuation of construction workers in the event of mudslides and water surges, ensured safe communication and emergency supplies, and improved the reliability and efficiency of the escape system.

Abstract

The present application belongs to the technical field of tunnel construction, and discloses a karst tunnel sudden mud and water gushing escape system and method, which comprises a secondary lining trolley arranged in the tunnel, a refuge platform arranged on the tunnel spandrel, and a transfer mechanism for transferring workers on the refuge platform to the secondary lining trolley. The refuge platform is suspended in the tunnel and is connected with a crawling ladder. The transfer mechanism comprises a transmission device, which comprises a driving wheel arranged above the secondary lining trolley and a driven wheel arranged above the refuge platform. The driving wheel and the driven wheel are drivingly connected with a cable. The transfer mechanism further comprises a driving device for driving the transmission device and a fixing device for fixing the driving wheel and the driven wheel. By arranging the refuge platform, workers can be quickly and temporarily transferred to the refuge platform, and then transferred to the secondary lining trolley by the transfer mechanism, thereby effectively solving the problem that the existing escape mode cannot timely transfer due to large water volume and high speed.
