[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] operation process 1. Conducted before construction field leveling, slurry trench dug row, good rig positioning. Requirements rig placed to maintain the level of Siping high pressure jet grouting pile driver model, drill held vertically, the inclination of not more than 1.5%. 2. Hole: Hole should be determined according to the geological conditions and rig technology functions into the hole in the standard soil penetration value of less than 40 N in a single tube injection job, grouting pipe can be directly inserted vibration rig; under normal circumstances can be Geological drilling rig into the hole using a pre-Siping high pressure jet grouting pile type, pore diameter is generally 75 ~ 130mm; Siping high pressure jet grouting pile hole wall when the model is easy to collapse, should casing. 3. Intubation: The grouting tube into a predetermined drilling depth Siping high pressure jet grouting pile driver model, grouting pipe connecting joints should be sealed. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] quality control due to the high pressure spraying pile construction difficult, according to the engineering construction rules formulated in strict compliance with the construction to ensure construction quality. 1. The cement should be product certification and product quality certification documents can be used. 2. Churning Pile strength must meet the design requirements. 3. Surveying: Construction axis tolerance of 1cm. Measuring ground elevation aperture tolerances of no more than 1cm, given hole tolerance of no more than 2cm. Aligned with the central axis of the drill hole to allow deviation does not exceed 2cm.
