Grouting device for shield tunneling machine

Abstract

The invention relates to the technical field of shield tunneling machines, and discloses a grouting device for a shield tunneling machine. The grouting device comprises a rack and a grouting barrel, wherein the top of the grouting barrel is provided with a grouting opening, a slurry inlet and a grouting pump, a stirring shaft is arranged in the center of the side face of one end of the grouting barrel in a penetrating mode, a stirring mechanism is arranged at the end, located in the grouting barrel, of the stirring shaft, the stirring mechanism comprises a connecting rod and stirring blades, a stirring motor is arranged at the end, away from the stirring mechanism, of the stirring shaft, a sliding rail is slidably connected to a stirring motor base, a sliding connecting plate is connected to the stirring motor base, the sliding connecting plate further comprises a sliding limiting hole, a moving device is arranged on the lower portion of the sliding connecting plate, the moving device comprises a supporting plate, a moving motor, an eccentric wheel and an eccentric shaft, and the eccentric shaft is embedded into the sliding limiting hole to be in sliding connection. According to the grouting device for the shield tunneling machine, slurry is not prone to being solidified to cause blockage, sufficient stirring is achieved, and meanwhile cleaning is convenient.

Description

Technical field [0001] The present invention relates to the field of shield machine, and is specifically a grouting device for a shield. Background technique [0002] Shield machine is a tunneling machine using a shield method. The construction method of the shield is to build (laying) tunnel * # * shield * # * (refer to the support tubes) while excavating machines, which distinguishes between open construction methods. The tunnel mounting tool has high automation, saving manpower, fast construction speed, one-time hole, not affected by the climate, reducing the ground settlement, reducing the impact on ground buildings and underwater When you dig, it does not affect the characteristics of ground transportation. When the tunnel cable is long, the shield is constructed is more economical and reasonable. [0003] During the transition of the shield, it is necessary to fill the appropriate amount of injection through the synchronous grouting of the shield tail void (i.e., the constr...

AI Technical Summary

Problems solved by technology

[0004] However, the current grouting device for shield machines takes too long to stop grouting, and the grout left in the grouting pipe hardens, causing blockage. The grouting pipe needs to be removed to remove the blockage, and the operation process is relatively complicated. Affected the working efficiency of shield machine tunneling
