2results about How to "Reduced torque requirements" patented technology

This utility model relates to the field of engineering machinery and equipment technology, and provides a jet grouting pile device, which solves the technical problem that traditional large-diameter pile construction often requires large-tonnage, high-torque jet grouting machines, resulting in high energy consumption. The jet grouting pile device includes a drilling tool, which includes a drill bit assembly and at least one set of agitator blade units fixed to the outer periphery of the drill bit assembly and distributed in a ring-shaped interval. The drilling tool is a rotary jet grouting drill, and the drill bit assembly is provided with lateral nozzles; the agitator blade units include agitator blades and breaking teeth distributed on the agitator blades, and the injection channel of the nozzle is not higher than the breaking teeth.
