DJM DJM pile design is typically 50cm diameter pile supporting Jet injection pump, designed to penetrate soft soil pile length and should reach the bearing layer within 50cm. Pile spacing and stability and the settlement of related embankment, pile spacing should be a minimum of 1.1 ~ 1.2m, pile positioned on the plane was arranged in equilateral triangular or rectangular. To improve the embankment underside of force conditions, DJM Embankment should lay down about 30cm lime soil cushion. CFG pile in soft foundation treatment of high speed depending on the characteristics of the jet grouting pile in expressway construction, soft ground treatment methods are not the same type of jet grouting pile 50, focuses on the construction of the highway CFG pile composite foundation treatment method detection process quality control measures and the reinforcement effect of jet grouting pile prices provide a reference for similar projects in soft ground treatment. Soft ground treatment with the rapid development of highways, various methods of soft foundation treatment 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.
