Double trolley type tunnel grouting machine

Abstract

The invention discloses a double trolley type tunnel grouting machine. The double trolley type tunnel grouting machine comprises a left trolley and a right trolley with the same structures; a water tank is arranged between the left trolley and the right trolley; the left trolley, the right trolley and the water tank are arranged on a base; walking wheels are arranged on the lower portion of the base; the left trolley includes a grouting barrel, and the lower portion of the grouting barrel is connected with a grouting tube for grouting; a stirring shaft is arranged in the grouting barrel; stirring blades are arranged on the stirring shaft; the stirring shaft is connected with a motor; a water filling nozzle is arranged at the upper end of the water tank; a water injection pipe is also arranged on the water tank, and a pressure water pump is arranged on the water injection pipe; and an air outlet pipe provided with an air pump is also arranged. The double trolley type tunnel grouting machine has high construction efficiency, time saving as well as strong practicality and functionality, the stability in the grouting process can be ensured, and the position of the water injection pipeand the air outlet pipe can be adjusted.

Description

technical field [0001] The invention relates to the technical field of grouting equipment for tunnel construction, in particular to a double-trolley tunnel grouting machine. Background technique [0002] At present, the urban subway construction has tended to a white-hot stage. High-quality and high-standard tunnel construction technology plays a decisive role in the rapid development of subway construction, and the second lining construction in tunnel construction is a key link in tunnel construction; for the current In the construction of the second lining of domestic tunnels, the density and fullness of the second lining grouting are particularly important; however, the traditional second lining grouting technology not only affects the appearance quality of the second lining due to cumbersome construction, but also prolongs the construction period of the second lining and wastes various resources. Therefore, it is necessary to use a grouting machine for grouting. [0003...

AI Technical Summary

Problems solved by technology

[0003] The existing tunnel grouting machine is more troublesome in grouting, and the grouting efficiency is low, which affects the time of other processes; and the positions of the air outlet pipe and the water injection pipe cannot be adjusted, and the operation process is complicated; and the fixing of the air outlet pipe is inconvenient. It is easy to cause the grouting to be affected due to the insufficient firmness of the outlet pipe during use
