Tunnel pipe shed supporting structure

The utility model provides a tunnel pipe shed supporting structure, which belongs to the technical field of tunnel and underground engineering construction and comprises an arch frame, a pipe shed pipe, a reinforcing structure and a limiting piece. At least two lagging jacks are arranged at intervals along the depth direction of the tunnel; the pipe shed pipes are arranged on the arch frame at intervals in the circumferential direction of the arch frame, and a plurality of grout overflowing holes are formed in the inner end of each pipe shed pipe at intervals. The reinforcing structure is arranged in the pipe shed pipes in the axial direction of the pipe shed pipes. The limiting pieces are arranged between every two adjacent pipe shed pipes at intervals in the circumferential direction ofthe arch frame and used for limiting the pipe shed pipes in the radial direction. According to the tunnel pipe shed supporting structure, the reinforcing structures are arranged in the pipe shed pipesin the axial direction, a
