[Tianjin-strong high-pressure pump Co., Ltd. to recommend Star Products] 1, before the high-pressure jet grouting construction, the case must have a complete project construction materials and engineering geological survey near the pipelines, buildings, structures and other public facilities, when groundwater When the flow is faster, deep foundation pit anchor crawler rigs, special hydrogeological investigation should be carried out. 2, the abnormal situation in the construction process, the most advanced anchor rig, should immediately stop the construction, jointly analyzed by the relevant units or construction units of the organization supervising the investigation, design and construction, to solve problems, to eliminate quality problems and should form documents After the order to continue the construction. 3, should be carried out before the official construction site injection test, Heihe City anchor rig to determine the appropriate construction speed parameter processing in soft ground by jet grouting pile with the rapid development of highways, various methods of soft foundation treatment have also developed stand up. Cement CFG referred to high pressure spraying pile, it is in the gravel pile reinforcement developed on the basis of a foundation formed by the addition of cement, fly ash, stone chips and sand-water mixture formed pile high bond strength , and soil between piles, CUSHION together form a composite. Shi Shi fight order to fight the order and spacing of the nature of the soil and the pile about: in soft soil, the hydraulic anchor drilling rigs, pile away from the larger, can be separated pile-hop beat, construction in saturated loose silts, as compared pile spacing small, continuous application play on Full fabric pile, regardless of the size of the pile spacing, are not pushed inwards from the surrounding construction should be used to promote the program or from the center outward from one side to the other side of the advancing program.
