[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] single pipe high pressure rotary jet pile control 1, according to the duration and other design work and combine predisposition, drawn into the machine, depending on site conditions adjustments. Appoint management staff responsible for safe construction, preparation of a good machine number, water-cement ratio, pile length and other signs made clear unified hanging hold to pile the specified location. 2, before the jet grouting, to check high-voltage equipment and piping systems. Pressure and displacement devices must meet the design requirements, the use of high-pressure pump, valve response was measured, its operation must be reliable. Seal piping system must be well, may not have within each channel and nozzle debris, Qiqihar mud pump, slurry feed pipe cleaning with water, check for clogging, ensure proper construction. Triple pipe high pressure rotary jet grouting pile reinforcement principles and methods of rig operations by a special triple injection tube, the injection tube ends by the three nozzles, mud pump accessories, namely high pressure water jet, compressed air and water slurry. The jet from the high pressure water and compressed air to cut the soil formation, ejection by another nozzle of the grout mixed with the soil to be cut to form cement, soil mix, achieve the purpose of Reinforced Earth. Since the injection tube rig operations side injection, jet grouting supporting mud pump, while rotating, while improved, thereby forming a cylindrical soil has a high strength cement plus solid, called jet grouting piles. If side injection side upgrade without rotating, then mix in the soil cement and soil implemented within the scope of the sheet.
