Pipe shed for reinforcing rock-soil layer

The invention discloses a pipe shed for reinforcing a rock-soil layer, and belongs to the technical field of reinforcing devices. The pipe shed for reinforcing the rock-soil layer is characterized in that a plurality of first through holes are formed in the bottom pipe wall of a pipe body, and the bottom outer wall is tightly attached to a bottom plate; a supporting structure comprises a top plate, a lifting device and four supporting rods, the top plate is tightly attached to the inner wall of the top of the pipe body, the top ends of the two supporting rods are hinged to the two sides, in the length direction of the pipe body, of the top plate, the two supporting rods on the same side intersect with each other, and the bottom ends of the supporting rods abut against the bottom wall of the pipe body; the middle of the top plate is fixedly connected with a base of the lifting device, the head of the lifting device penetrates through the first through hole and abuts against the bottom plate; one end of each reinforcing column abuts against the side wall of the pipe body, and the other end of each reinforcing column penetrates through the first through hole to abut against the bottom plate. The whole process is used for counteracting ground stress loss caused by engineering construction, so that the influence quantity of disturbance on an existing underground structure is reduced, the stress of a rock-soil body is controlled, a rock-soil layer of underground facilities is effectively reinforced, and the underground facilities are protected.
