High pressure jet grouting pile waterproof curtain construction device and method
The invention relates to a high pressure jet grouting pile waterproof curtain construction device and method. The device comprises a drilling machine, a machine frame, a high pressure cement slurry pump, an air compressor and a grouting pipe. The machine frame is arranged on the drilling machine. The end of the machine frame is provided with a pulley and connected with the air compressor through a steel wire rope on the pulley. The high pressure cement slurry pump and the grouting pipe are sequentially arranged below the air compressor. A pipe head of the grouting pipe is provided with a spray nozzle and sprays out a jet grouting induration body through the spray nozzle. The method carried out through the device is little influenced by soil layers, soil granularity, soil density, hardener viscidity and hardener hardening time and can be widely applied to various soil layers such as sludge, mucky soil, cohesive soil, silty clay, clay, sandy loam, sandy soil, loess, plain fill in artificial fill and even gravelly soil; by means of the construction technology of directly forming a pile through grouting after hole formation, the hole forming quality is improved, the construction cycle is shortened, and the construction cost is reduced.
