Hole slip casting;After grouting pressure exceedes the grouting pressure design load of relief valve, relief valve automatically opens up carry out pressure release, data acquisition
Analyzer is alarmed automatically.If slurry pool is two or more, other slurry pools by pressure duct, grouting pump to
Slip casting orifice tube carries out slip casting.After slip casting terminates, relief valve, pressure sensor and pressure duct etc. are cleaned in time.
The utility model has the advantage of:The utility model can guarantee that slurries smoothly pass in and out energy storage equipment;Relief valve is gone out
Mouth is connected in slurry pool by pressure duct, in order to avoid cause slurries unrestrained after exceeding setting pressure due to pressure during slip casting
Take.Stable grouting pressure can be provided for slip casting process to a certain extent when grouting pressure gathers during slip casting;When slip casting pressure
After power exceedes setting value, by relief valve releasing pressure automatically, the purpose for controlling maximum grouting pressure is realized;Pressure sensor and data
Collection analysis device is connected, in order to monitors the grouting pressure during slip casting.The utility model is controlled using final grouting pressure
Device not only saves injecting paste material, while also solves to cause high-speed railway rail level upward because final grouting pressure exceedes design pressure
The problem of lifting, it can effectively block and cover karst water under high-speed railway existing line roadbed, increase the stability of roadbed base plate, solve
Certainly subgrade deformation destabilization problems.
