[Tianjin-strong high-pressure pump Co. Recommended star product you] 1, before the high-pressure jet grouting construction, ground treatment for culverts rig, you must have a complete engineering geological survey data and engineering nearby pipelines, buildings, structures and other public facilities structure, the Jet foundation treatment rig, when groundwater flow faster, should conduct a special hydrogeological investigation. 2, the abnormal situation in the construction process, subway foundation treatment rig, should immediately stop the construction, supervision or construction units of the organization by the survey, the unit design, construction, and other common analysis, problem solving, eliminate quality problems, and should form the documentation rear can continue construction. 3, should be carried out before the official construction site injection test rig Mudanjiang ground treatment, to determine the appropriate operation parameters Jet grouting rig main role is to pipe (on the bottom nozzle) to the design depth, to meet the design requirements of lift and rotation grouting pipe. At present, use of Tianjin-strong pile production models XPB-20, XP-50A, SP-30AB, XPL-50 crawler drills.
