Causes and prevention of difficult deflection of high pressure jet grouting pile bored pipe sinking
The construction site of the high-pressure jet grouting pile is uneven or unreal: it is difficult to ensure the level, integrity and stability when the drilling rig is installed in place; The high-pressure jet grouting pile is mainly applicable to the treatment of foundation soil such as silt, muddy soil, cohesive soil and artificial backfill soil. The drilling rig is horizontal, upright and stable when installed in place. However, the drilling rig is inclined or displaced during the drilling pipe sinking and rotary jet grouting process, which often leads to the drilling. Inadequate drill pipe perpendicularity, I .e. drill pipe inclination of more than 1.5 per cent, can also cause the borehole to be inclined.
