CFG pile in soft foundation treatment of high speed depending on the characteristics of residential basis soft foundation treatment of highway construction, soft ground treatment methods are not the same, focusing on CFG pile composite foundation treatment method in the construction process and the quality control measures highway Consolidation detection results provide a reference for similar projects in soft ground treatment. Soft ground treatment with the rapid development of various methods of soft-processing equipment manufacturers, soft foundation treatment of highway have also developed. Cement referred CFG CFG pile (Cernent Fly-ash Gravel) it is in the gravel pile reinforcement developed on the basis of a foundation formed by the addition of cement, fly ash, stone chips and sand-water mixture formed high Pile bond strength, and soil between piles, CUSHION together form a composite. SP-30B Level Jet Horizontal Jet Grouting rig is drilling in the horizontal way of a high-pressure jet grouting pressure water slurry, the outer contour of the tunnel excavation of a pre-formed arch lining to protect the working face and surface subsidence advance Support Construction Methods. Practice has proved that the level of domestic and foreign jet grouting pile is effective and fast economic tunnel advance support technology, has broad application prospects. The company on the basis of a large number of research results on the small Jet soft-processing equipment, the use of theoretical analysis of jet grouting pile was further improved soft ground treatment, and the use of a number of technical innovations, according to needs of the construction, production of utility model The small horizontal jet grouting pile.
