[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] single pipe high pressure grouting pile following principles (1) meet the construction site of advanced drilling rig construction conditions, followed by the gradual improvement of the construction site after construction is not construction general layout plan, follow into the pile. (2) a reasonable use of space, high-pressure pump manufacturers, wholesale, both to ensure Churning Pile can proceed smoothly, XPB-90E-pressure pump, and not much accounting for construction sites. (3) Drill travels the shortest route, and to facilitate construction. (4) consider the device into, exit required for the desired site, a high-pressure pump much money, and material transport carriage venue. (5) would minimize the environmental pollution caused by the construction. (6) to comply with the relevant provisions of labor protection, technical safety and fire regulations [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] operation process of No.21. Spray job: the job should be checked before the injection nozzle is blocked, lose pulp (water), gas leaks and other phenomena, no abnormal situation, to embark on the design requirements for spray operations. Construction process should always check the pressure gauge is shown in each normal, abnormal situation, Zibo high-pressure pump, should immediately stop the injection operation, until everything is back to normal, and then continue construction. 2. After completion of the injection operation, pull out the grouting pipe. 3. Pull out the grouting pipe, wash immediately with water injection pump and grouting pipes. When grouting frontier, available at last for cleaning. 4. After the initial setting grout sink, using cement slurry immediately recharge, recharge height should be higher than the design elevation.
