[Tianjin-strong high-pressure pump Co., Ltd. to recommend common failings of governance star product] drilling common problem of governance: too large gradient drilling, drill and to drill difficult, Jinan jet grouting pile, drilled deep enough. Governance measures: should control the drilling depth, high pressure jet grouting pile, and promptly correct hole deviation, with drilling inclinometer inspection hole deviation measurements. Drilling depth is greater than the depth of grouting 0.5 ~ 1.0m. High-speed soft foundation treatment of high pressure spraying pile in with the rapid development of highways, twin jet grouting pile, various methods of soft foundation treatment have also developed. 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, away from the big pile, the pile can be separated hop beat, buy rotary jet pile construction in saturated loose silts, as pile From small, then applying continuous play on Full fabric pile, regardless of the size of the pile spacing, are not from around promoting inward construction should be used to promote the program or from the center outward from one side to the other side of the advancing program.
