Abstract

The invention discloses a mixing system of injected pulp in metro shield construction. The mixing system comprises a rail, a trolley, a windlass, a spiral conveyor, a sand field and a horizontal stirrer; the rail is longitudinally arranged; the trolley is positioned on the rail; the windlass is mounted at the top end of the rail, and is connected with the trolley through a traction steel wire rope; the spiral conveyor and the sand field are both positioned on the same side of the rail; the horizontal stirrer comprises a barrel and a frame; the barrel is mounted on the frame through a connecting shaft; a racket is connected to the connecting shaft; the frame is provided with a pallet matched with the ratchet; an adjusting mechanism is arranged between the ratchet and the frame, and comprises a chute and a slide block; a limiting rod is arranged in the chute; the slide block is rotationally connected with the pallet; and a torsion spring is arranged in the connected place. The mixing system solves the problem of inconvenience to clean of mixing equipment in the prior art.

Description

technical field [0001] The invention relates to a mixing system for pressure grouting in subway shield construction. Background technique [0002] Shield method is a comprehensive construction technology. The main content of the shield tunneling method construction is: first build a shaft or foundation pit at one end of a certain section of the tunnel for the shield to be installed in place. The shield starts from the reserved hole in the wall of the vertical shaft or foundation pit, and advances to the designed reserved hole of another vertical shaft or foundation pit along the design axis in the stratum. The stratum resistance encountered during shield tunneling is transmitted to the assembled prefabricated lining at the tail of the shield through the shield jack. The shield is a circular steel cylinder structure that can support the formation pressure and can be pushed in the formation. Its diameter is slightly larger than the diameter of the tunnel lining. Various type...
