[0002] Recently, my country's infrastructure construction has been accelerated, especially in tunnel construction, which has achieved world-renowned achievements. There are two methods of excavating rocky surrounding rock tunnels: blasting method and shield construction method. The progress is slow, and the shield tunneling method has the following problems: (1) The construction speed of the shield tunneling method is slow because the entire section needs to be excavated. Use drilling, excavation, blasting and other methods to assist the construction, which increases the construction cost and the construction period. (3) There is a problem of over-excavation in the construction of large-span tunnels using large shield machines
The construction section of the large-scale shield machine operation is a circumscribed circle, while the actual effective area required by the expressway tunnel is only a part of the circumscribed circle, and the over-excavation is more than twice the actual need, which not only increases the construction cost but also increases the impact on the mountain. (4) When the shield machine is working, the stone will be broken in the whole section, and a large amount of waste will be generated. A large amount of waste needs to be transported and discarded, occupying a large amount of space, which is not conducive to environmental protection. In this regard, provide A tunnel forming machine and construction technology for stone surrounding rock tunnels with one-time hole formation, small excavation volume, fast construction speed, less waste, raw material saving, low engineering cost, and environmental protection are of great significance
