Description

Technical Field

[0001] The utility model relates to the technical field of grouting machinery, in particular to a grouting machinery for road and bridge construction. Background Art

[0002] As we all know, grouting machine is a kind of equipment widely used in bridge and tunnel construction. Grouting usually refers to the use of pure cement slurry with external additives. Before grouting, the hole to be grouted is first flushed with pressurized water, and then the pure cement slurry is pressed into one end of the hole. The other end is discharged with thick slurry and then sealed. The pressure is increased to 0.5-0.7 MPa and continued for 3-5 minutes. The slurry can protect the steel strand from rusting and extend the service life of the structure, so the grouting should be full and dense; secondly, as a medium, it transfers part of the stress to the beam body after the steel strand is relaxed.

[0003] A grouting machine for tunnel and bridge construction with a search announcement number of CN 219235700 U includes a main body, a crushing and filtering mechanism and a stirring mechanism. The crushing and filtering mechanism is located at the upper end of the inner end of the main body, and the stirring mechanism is located at the lower end of the inner end of the main body. The main body includes a bottom plate, a universal wheel, a foot brake, a box body and a push handle. The universal wheel is fixedly installed at the lower end of the bottom plate, and the foot brake is movably installed at the right end of the universal wheel. The box body is fixedly installed at the upper end of the bottom plate, and the push handle is fixedly installed in the middle of the rear end of the box body. The grouting machine for tunnel and bridge construction is easy to crush larger cement materials by installing a crushing and filtering mechanism, avoiding the problem of blockage, reducing maintenance work, reducing the workload of staff, reducing labor intensity, improving work efficiency, improving construction quality, and improving practicality.

[0004] However, there are still some shortcomings in the use of the above-mentioned machinery. Large materials such as cement are only crushed once, and the crushing effect is poor, which affects the use of the grouting machinery. At the same time, some incompletely crushed materials will accumulate on the screen plate, causing the screen plate to be blocked, which is difficult to clean and inconvenient to use.
