Telescopic adjustable small-angle advanced pipe shed device suitable for soft soil tunnel

The invention provides a telescopic adjustable small-angle advanced pipe shed device suitable for a soft soil tunnel. The telescopic adjustable small-angle advanced pipe shed device comprises a pipe shed pipe which is controlled to stretch out and draw back through hydraulic pressure, a drill bit assembly and a pushing cylindrical block. Wherein the upper end of each pipe shed pipe is arranged at the bottom end of each drill bit assembly in a sleeving manner, and the drill bit assemblies can freely rotate in the pipe shed pipes; the bottom end of the pipe shed pipe is fixed on the pushing cylindrical block; the pipe roof pipes comprise a first pipe roof pipe, a second pipe roof pipe and a third pipe roof pipe; the pushing cylindrical blocks comprise a first pushing cylindrical block, a second pushing cylindrical block and a third pushing cylindrical block; the pipe shed pipes and the pushing cylindrical blocks are correspondingly mounted; and the pushing cylindrical blocks are hydraulically connected.
