Abstract

The invention relates to the technical field of grouting equipment, in particular to a grouting equipment for shield tunnel construction, comprising a mobile frame and a plurality of grouting pumps, the mobile frame is connected with a back bucket, and the plurality of grouting pumps are installed on the back Inside the bucket and the back bucket are installed a plurality of stirring devices, the grouting pump is connected with the stirring device, the mobile frame is connected with a slurry changing device and a slurry lifting pipe, the slurry changing device is connected with a plurality of slurry feeding pipes, and the slurry feeding pipe is connected with the slurry injection pipe. The slurry pump is connected, the slurry lifting pipe is connected with the slurry changing device, and the slurry lifting pipe is connected with the slurry changing device. The moving frame is equipped with a driving device and a folding lifting mechanism. The folding lifting mechanism is installed with a working bucket, and the working bucket is connected with a stabilizer frame Swing door, two stabilizing devices and two elastic mechanisms are installed between the operation bucket and the folding lifting mechanism and the swing door, respectively, and there are strip holes on the swing door. The tunnel grouting effect is better, the efficiency is higher, and the limitations It has low performance, and the conversion of slurry with different concentrations is more flexible and practical.

Description

technical field [0001] The invention relates to the technical field of grouting equipment, in particular to a grouting equipment for shield tunnel construction. Background technique [0002] As we all know, grouting equipment for shield tunnel construction is a kind of grouting equipment used for tunnel construction in order to facilitate tunnel construction and use safer auxiliary devices. widely used. [0003] The existing grouting equipment for tunnel construction includes a grouting pump and a mixing tank. The grouting pump is connected to the mixing tank, and the output end of the grouting pump is connected with a grouting pipe. When it is used, holes are first drilled in the tunnel to install anchors. Then install the control valve on the anchor pipe, connect the grouting pipe to the control valve, start the mixing tank, put the stirred slurry in the mixing tank, open the control valve, start the grouting pump, and the grouting pump will stir The slurry in the tank i...
