More Information
Summary:The utility model provides a grouting final pressure control device. The grouting final pressure control device comprises high-pressure pipelines arranged on a first slurry pool and a second slurry pool respectively; the three-way pipe is fixedly mounted on the two high-pressure pipelines; the connecting pipe is fixedly mounted on the three-way pipe; the final pressure control mechanism is arranged on the two high-pressure pipelines and the connecting pipe; the outer sleeve is fixedly mounted on the connecting pipe; the pressure relief pipe is arranged on the connecting pipe; the strip-shaped groove is formed in the pressure relief pipe; and the multiple pipeline fixing mechanisms are all arranged on the outer sleeve. The grouting final pressure control device provided by the utility model has the advantages that the problem that the rail surface of the high-speed railway is lifted upwards due to the fact that the grouting final pressure exceeds the designed pressure can be effectively solved, and the stabili
