Problems solved by technology

[0003] The interior of the existing grouting trolley only serves to store the prepared mud. When the mud is used up, it is necessary to remove the grouting trolley from the tunnel again, and then re-inject the cement slurry. The operation is more troublesome, so that The efficiency of grouting behind the wall is reduced and the speed is slowed down

Abstract

The invention discloses a self-propelled grouting trolley equipment for subway shield tunneling construction, which comprises a trolley frame and a slurry storage box arranged on the trolley frame, and horizontal pipes are arranged at both ends of the trolley frame And the end of each horizontal tube is provided with a side convex body, the bottom end of the side convex body is provided with a walking slide, and the sliding seat of the walking slide is fixed on the walking guide rail fixed on the tunnel floor, and the two side convex bodies are arranged between There is a horizontal axis of rotation and a walking drive gear is installed on the horizontal axis of rotation. The driving gear is engaged with the horizontal toothed rack arranged on the ground of the tunnel. The outer wall of the slurry storage box is provided with a walking motor and a driving horizontal axis. , both sides of the vehicle platform are provided with a grouting mechanism for ejecting the grout inside the grout storage box. The invention has a simple structure, can facilitate the reciprocating automatic walking of the whole trolley in the tunnel, can realize rapid grouting, is convenient to operate and has strong practicability.

Description

technical field [0001] The invention relates to a large field, in particular to a self-propelled grouting trolley equipment for subway shield construction. Background technique [0002] Subway shield tunneling is an important construction technology in urban subway construction, and it is a construction method for digging tunnels underground. It uses the subway shield machine to excavate underground, while preventing the soft ground excavation surface from collapsing or maintaining the stability of the excavation surface, while safely performing tunnel excavation and lining operations inside the machine. The construction process needs to excavate a shaft or a foundation pit at one end of a certain section of the tunnel, hoist the subway shield machine into the installation, and the subway shield machine starts to excavate from the wall opening of the shaft or foundation pit and advances along the designed hole line until To reach the end of another shaft or tunnel in the ho...
