[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] which are available engineering geology Triple Tube Rotary Jetting? Triple tube Jet Grouting technology, mainly used in soft soil loose Puyang double-pipe jet grouting pile, such as Quaternary red (Hong) laminated, eluvial, sandy soil, clay soil, silt, loess, artificial fill and mud, mucky soil. But for the groundwater flow rate is too large, triple tube Jet Grouting cement or groundwater has eroded formations, generally should not be used triple tube rotary jet grouting. [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 improve the strength of the site Puyang double pipe jet grouting pile, 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 Puyang double-pipe jet grouting pile, should quickly pull out the injection tube; slurry solidification shrinkage effect in order to prevent the pile height, if necessary take take slurry recharge or secondary grouting and other measures in the original hole; 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.
