Due to the lightweight, easy disassembly, and transportation of ultra-high molecular weight polyethylene tunnel escape pipeline materials; The pipeline has good toughness and high impact resistance. When subjected to strong external forces, it instantly deforms, absorbs a large amount of impact energy, and then quickly returns to its original shape, providing extremely safe and reliable guarantee for emergency rescue and evacuation in highway tunnel construction; The pipeline ring has high stiffness, good pressure resistance, and is not easily deformed. In the event of collapse during highway tunnel construction, its pressure bearing capacity and resistance to environmental damage far exceed that of ordinary pipelines. The transportation department adopts new materials (ultra-high molecular weight polyethylene) for highways The emergency rescue channel for tunnel construction has been designed. At the same time, the structural dimensions of the new emergency rescue channel comply with ergonomic principles Simple and easy to disassemble. Finally, a comparative impact resistance test was conducted on ultra-high molecular weight polyethylene escape pipes and steel pipes to verify the reliability of using ultra-high molecular weight polyethylene escape pipes for emergency rescue in tunnel construction.
