Description
Technical Field

Background
Along with the development of urban rail transit construction in China, the shield construction technology is rapidly developed in China, and the current tunnel construction mostly adopts a shield machine for tunneling. The inner diameter of the shield is larger than 5.5m, the pipe piece is annular, a plurality of work stations cannot be completed on the bottom plate or on the shield in the shield tunneling process, for example, errors exist in the installation of the shield pipe piece, the mounting grouting of the pipe piece can also generate water leakage problems along with the pushing of the shield machine, the pipe piece is required to be repaired and subjected to secondary grouting, synchronous grouting is required in the shield tunneling construction, concentrated load is generated by the pipe piece due to the fact that synchronous grouting is accompanied with the indispensable quality defects of a large-scale cavity and the like, the safety risk of the tunnel is increased, the pipe piece wall is required to be subjected to secondary grouting in time for ensuring the integral stress of the pipe piece, in addition, the pipe piece is required to be subjected to re-tightening work for preventing sedimentation, floating and deformation of the formed pipe piece after the pipe piece is assembled, and a large amount of soil or mechanical construction grease is required to be stained in the pipe piece in the installation process. Because grouting holes are distributed on the pipe piece in an annular mode, grouting work for the middle upper portion and repair and cleaning work for the middle upper portion pipe piece can be completed by aid of auxiliary mechanisms. Because of the specificity of the shield tunnel, the traditional mode of the overhead operation in the shield tunnel at present adopts a herringbone ladder, a single-sided ladder, a temporary scaffold, an assembled portal frame and the like, most of the overhead operation auxiliary brackets have unsafe factors, most of the overhead operation auxiliary brackets are only temporarily built and are detached along with the construction, only spot-face construction can be met, the shield tunnel is difficult to move, has poor maneuverability, low efficiency, poor stability and low safety, the requirements of full-section construction of a full tunnel cannot be met, and the shield tunnel also needs to be internally provided with tunnel construction equipment such as an electric vehicle, and the normal construction of other equipment in the tunnel can be influenced by temporarily building an overhead operation platform.
