Embodiment Construction
[0031] The present invention will be described in detail below in combination with specific embodiments.
[0032] Prefabricated buildings are a major change in construction methods, which are conducive to saving resources, reducing construction pollution, improving the working environment, increasing production efficiency, and promoting standardized construction. Drilling and blasting tunnels can replace the traditional inverted arch trestle model after adopting the assembled inverted arch. After the inverted arch is prefabricated and assembled, it can be closely followed by the excavation tunnel face to achieve rapid installation and construction. While ensuring the quality of the inverted arch, it also improves Tunnel security. Due to various factors, the current construction method of drilling and blasting tunnels is still mainly cast-in-place, and the proportion of drilling and blasting prefabricated tunnel construction is still very low, which is still far behind the nati...
