Technical Field
[0001] The utility model relates to the technical field of tunnel emergency escape passages, in particular to a novel high-density composite material tunnel emergency escape passage. Background Art
[0002] With the continuous progress of my country's economy and society, the importance of various infrastructure construction has become increasingly prominent. The construction of railways, highways, bridges, rail transit, etc. is in full swing. They not only connect all corners of the city, but also promote economic exchanges and social development between regions. Especially when crossing natural obstacles such as mountains, tunnels have become the preferred mode of transportation due to their high efficiency and safety. However, with the continuous expansion of the scale of tunnel construction, safety issues in the construction process have gradually become prominent. Due to the complex and changeable geological conditions in my country and the inappropriateness of some construction methods, landslides occur frequently during tunnel construction. These accidents not only cause casualties and major economic losses, but also have a serious impact on the construction progress and quality of the tunnel. In order to protect the lives of tunnel construction personnel and reduce economic losses, the "Technical Specifications for Highway Tunnel Construction" clearly points out that when tunnel construction is carried out under specific surrounding rock conditions such as taro, yu, and yu, tunnel escape devices must be used. These devices can provide construction personnel with a fast and safe escape route in the event of an emergency such as a tunnel collapse, thereby minimizing casualties.
[0003] The existing new type of high-density composite material tunnel emergency escape passage connection method relies on the accessory clamp connection. Although this connection method can meet the basic needs of tunnel emergency escape to a certain extent, it will cause many unnecessary troubles in actual use. For example, the fasteners of the accessory clamp connection become loose or damaged, which affects the stability of the escape passage. At the same time, due to the large number of connecting parts, the installation process is relatively complicated, resulting in a long installation time and low efficiency. In addition, since professional installation skills and experience are required, this connection method also increases labor costs. Utility Model Content

[0006] By adopting the above technical solution, the fixing plate is first pressed to make the sliding tube slide in the fixing tube, so that the fixing plate presses the spring, so that the fixing plate extends into the installation groove, and then the fixing block extends into the connecting part. When the fixing plate corresponds to the fixing opening of the connecting part, due to the reset function of the spring, the fixing plate will be pushed out, so that the fixing plate passes through the fixing opening, thereby connecting the two escape parts. In this way, it is possible to avoid the problem that the fasteners connected to the accessory clamp become loose or damaged, resulting in the stability of the escape passage being affected.

[0015] Preferably, the connecting portion further comprises a fixing opening opened on one side of the connecting groove and a sealing ring welded to one side of the connecting block.
[0016] By adopting the above technical solution, the sealing ring is used to enhance the sealing performance of the connection between two new high-density composite material tunnel emergency escape passages.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. By providing a connecting part and a fixing part, the fixing plate is first pressed to make the sliding tube slide in the fixing tube, so that the fixing plate presses the spring, so that the fixing plate extends into the installation groove, and then the fixing block extends into the connecting part. When the fixing plate corresponds to the fixing opening of the connecting part, due to the reset function of the spring, the fixing plate will be pushed out, so that the fixing plate passes through the fixing opening, so that the two escape parts are connected, so that the fasteners connected by the accessory clamp can be prevented from being loosened or damaged, resulting in the stability of the escape passage being affected;
[0019] 2. By setting up an escape section, when an emergency occurs, such as fire, collapse, etc., the escapees can follow the instructions or training to untie or open the entrance of the escape passage and quickly enter the passage. Since the first high-density composite material layer and the second high-density composite material layer are spirally wound together, the passage has better strength and resilience, so that when encountering obstacles or deformation, the escapees can release the additional load through a certain deformation and continue to move forward. Then, the friction layer design can increase the friction force to prevent the escapees from slipping and causing trampling. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 3
[0033] See also Figure 4A novel high-density composite material tunnel emergency escape passage, comprising a connecting block 401, a connecting groove 402, a fixing port 403 and a sealing ring 404: a connecting portion 4 is welded on one side of the inner wall of the channel shell 1, the connecting portion 4 comprises a connecting block 401 welded to the inner wall of the base channel shell 1, the connecting block 401 is rectangular in design, and is used to provide installation conditions for the components of the connecting portion 4, a connecting groove 402 is provided on one side of the connecting block 401, the connecting groove 402 is rectangular in design, and is used to fix the fixing block 301, the connecting portion 4 also comprises a fixing port 403 provided on one side of the connecting groove 402, the fixing port 403 is an arc in design, and is used for the fixing plate 306 to extend therein, and fix the connecting portion 4 and the fixing portion 3, and a sealing ring 404 is welded on one side of the connecting block 401, and the sealing ring 404 is an arc in design, and is used to enhance the sealing at the connection between two novel high-density composite material tunnel emergency escape passages.
