R&D and Application of Bamboo Winding Composite Tunnel Escape Tube
Due to the heavy weight and inconvenient movement,the daily use rate of the traditional tunnel escape pipe is not high,which causes great potential safety hazards.Bamboo winding composite pipe is a new type of bio-based material based on bamboo,which inherits the excellent mechanical properties of bamboo,and the proportion of the material is small,and the carbon emission in the production process is low.In this paper,the bamboo winding composite pipe for the escape passage was designed,its cross-sectional size was determined,and the mechanical verification was carried out through the test,and the results showed that the bamboo winding composite pipe was superior to the PE pipe used in the mainstream use.Then,through theoretical analysis and finite element simulation,the stress of the bamboo winding composite pipe under the impact collision condition was calculated,and the force of the pipeline under the extreme static load condition was simulated and calculated.The results showed that the application of bamboo winding composite pipe in tunnel escape routes is feasible,and its main application advantages were briefly described.The low-carbon portable bamboo-wound composite pipe escape channel developed by the company has been successfully applied in the high-speed railway tunnel project,and has achieved good economic and environmental benefits.
