[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product - high-pressure pump] Features: GZB-40C-pressure injection pump high-pressure jet grouting equipment, mainly to provide high-pressure water spray high-pressure mud spin. For the new building, highway, railway, underground railway soft foundation reinforcement sealing curtain jet grouting pile for processing seepage around foundation, cofferdam and hydropower dams. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] Churning Pile details of claims 1 rotary jet pile construction parameters should be based on soil conditions, strengthening requirements through tests or according to engineering experience, and should be strictly controlled in construction ; high-pressure water slurry single tube method and double-tube method and the three-tube method high pressure of the water treatment should be greater than 20MPa; 2 cement slurry cement ratio should be asked to identify projects, it is desirable 0.8 to 1.5, should be adopted 1.0 ; three pairs of reinforcing the need to expand the scope of partial or increase the strength of the parts of the jet grouting pile foundation reinforcement, measures can be taken to re-spray; 4 The sudden pressure drop in the construction process. When abnormal rise or take slurry, should identify the cause and to take timely measures; 5 Churning Pile completed Churning Pile manufacturers should quickly pull out the injection tube; slurry solidification shrinkage effect in order to prevent the pile height, if necessary, in the original hole Bit take oozing slurry recharge or secondary grouting and other measures; 6 construction should be prepared to deal with mud, and the mud should be shipped out in the field or out of the short stack made after earthworks.
