[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 Xinyang sealing curtain Churning Pile, such as Quaternary red (Hong) laminated, eluvium Xinyang sealing curtain jet grouting pile, sandy soil , clay soil, silt, loess, artificial fill and mud, mucky soil. But for the groundwater flow rate is too big, Xinyang sealing curtain Churning Pile, triple tube Jet Grouting cement or ground water have eroded formations, generally should not be used triple tube rotary jet grouting.
