[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 placed to maintain the level rig, drill pipe 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, Suihua ground handling rigs, standard penetration in soil N value of less than 40 in a single tube injection job, Jet rig foundation treatment, can be vibration Drill pipe is inserted directly grouting; geological drilling rig can be used in general advance into the hole, into the hole diameter is generally 75 ~ 130mm; when the hole wall easily collapse, should casing. 3. Intubation: The grouting tube into a predetermined depth drilling, grouting pipe connecting joints should be sealed. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product]
