Abstract: In the soft soil layer, the contact channel is usually constructed by mining method, and the surrounding soil is reinforced by grouting or freezing. The conventional freezing method has problems such as ' long construction period, high cost and quality hidden danger ', and grouting reinforcement has problems such as ' occupying ground space '. In order to solve the unfavorable factors caused by the above construction methods, this paper puts forward the technology of non-reinforcement and mechanical construction of contact channel. This technology has certain advantages in safety, construction period and cost. It is of positive significance to systematically carry out the research and development of mechanical connection channel technology to promote the development of the industry and improve the technical level of underground engineering. In order to deal with the difficulties and risks of the construction of the mechanical method connecting passage in the region, based on a tunnel project, the construction quality management system of the mechanical method connecting passage is expounded, and the on-site monitoring and analysis are carried out. The results show that the construction technology applied in this project is conducive to improving the construction efficiency and ensuring the construction safety. The research results can provide reference for the mechanical construction of the connecting passage under similar stratum conditions.
