Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering construction, specifically to an emergency refuge and escape device for tunnel construction. Background Technology

[0002] When encountering adverse geological conditions during tunnel construction, disasters such as collapses, mudslides, and water inrushes often occur, seriously endangering the lives of workers. Currently, the common practice is to install escape pipes near the tunnel face to provide temporary refuge for workers, along with emergency supplies such as medical kits and food. However, in actual incidents of collapses, mudslides, and water inrushes, the escape pipes are often too small in diameter, making it difficult for workers to quickly enter. Furthermore, these escape pipes cannot be sealed, allowing water to directly enter during mudslides and water inrushes, threatening the lives of those seeking refuge. Therefore, it is necessary to install a new type of emergency refuge and escape device for tunnel construction to enable workers to quickly enter refuge boxes and effectively seal them in the event of a water inrush.

[0003] Currently, one of the methods used for emergency refuge and escape during tunnel construction is the tunnel face escape pipeline. The tunnel face escape pipeline is a steel pipe with a diameter of φ600~φ800mm and a wall thickness of not less than 6mm. Generally, each section is 3m or 5m long, and multiple sections are connected by clamp bolts. The escape pipeline is placed on the ground. Traditional escape tunnels have the following drawbacks: (1) The diameter of the escape tunnel is relatively small (600mm~800mm) and the space is limited. Only one person can crawl in at a time, and the crawling process is difficult and time-consuming. After the collapse of the working face or mudslide, the workers at the working face cannot quickly enter the escape tunnel for the above reasons, resulting in some workers still being exposed to the danger zone; (2) The escape tunnel is generally placed on the ground and the openings at both ends cannot be closed. Therefore, once the working face collapses and groundwater appears, the trapped personnel can only be bound in the escape tunnel; (3) The current escape tunnel is a long strip pipe structure with a thin wall (6mm steel pipe) and weak pressure resistance. Once hit by falling rocks, the personnel are easily injured and the passage is blocked.

[0004] Many domestic researchers have optimized the design of escape tunnels at the tunnel face. Zhang Xiangyuan et al. used flexible joints to address the difficulties in movement caused by inconsistent heights of tunnel steps. Sun Ziqian et al. studied the connection devices of escape tunnels, increasing the survival rate of personnel inside. Zhang Yongsheng et al. improved the pressure resistance of escape tunnels by setting up double-layer escape tunnels. Yan Wanghu improved the current escape tunnels by setting inlets and outlets at the gates to mitigate the impact of falling rocks, but this could not prevent the influx of water. The reviewed data indicates that current escape tunnels and related improvements cannot overcome the above three shortcomings.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a refuge and escape device that can provide temporary refuge for workers and ensure their vital signs when encountering collapse, mudslide, or water inrush accidents during tunnel construction. Specifically, it solves the problem that traditional escape pipes cannot be sealed after workers enter, thus avoiding the problem that workers are still exposed to dangerous areas. At the same time, it can also provide refugees with positioning devices, temporary lighting, temporary power supply, and temporary communication means.

[0007] This utility model patent utilizes a cylindrical design with gradually increasing diameter to allow workers at the working face to quickly enter the escape tunnel. The diameter of the entry tunnel has been increased from 600mm-800mm to 1320mm, making it easier for evacuees to enter. The patent incorporates sealing devices at both the front and rear entrances, ensuring the safety of evacuees even after a collapse and flooding. Furthermore, the patent uses 40cm high outriggers to support the evacuee at ground level, eliminating the need for crawling and further improving evacuation efficiency.
