[Tianjin-strong high-pressure pump Co., Ltd. to recommend Star Products] Dual tube and triple swirler under high pressure is the use of the first drilling, and put people rotating nozzle, high-pressure jet cutting methods the soil and cement slurry was stirred, single solution injection pump, plus solid or foundation reinforcement methods cut-off wall is formed after mixing were cured. Double tube method is water and cement slurry injection at the same time, rotate, cement slurry spray nozzle, spray nozzle outside. Triple tube method, water, gas and cement slurry three media, grouting pipe consists of three coaxial pipe consisting of different diameters, the inner tube conveying water, piped gas flow in the outer tube transport cement slurry. High-pressure water jet cutting gas no shaft surrounding soil, so that adequate mixing of soil and cement slurry, while jet, Xinjiang injection pump, while rotating and lifting grouting pipe, forming a larger diameter plus solid. High-speed soft foundation treatment of high pressure spraying pile in with the rapid development of highways, 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, injection pump Wuhan, construction in saturated loose silts, as pile spacing smaller, the continuous application of play, Huizhou injection pump, for Full fabric pile, regardless of the size of the pile spacing, are not from around promoting inward construction, should be used to promote one side or the other side from the center outward from advancing programs program.
