TECHNOLOGY AND APPLICATION OF JG SOIL-CEMENT-PILE STRENGTHENED PILE IN INDUSTRIAL PROJECTS

JG (Jet Grouting) soil-cement-Pile strengthened pile (for short JPP)technology is an advanced technology and economic environment of new technology patents. Which was developped after years of study and practice, aim at coastal land area of soft pile lateral friction and lower-end resistance characteristics. JG(Jet Grouting) soil-cement-Pile strengthened pile combinations of high jet by the High Pressure Jet piles and piles into one of the core concentric pile composed by the pile of reinforced concrete core, of concrete, steel and other materials. JG use of reinforced soil, through hard soil or bottom of the pile-soil reinforcement and improve pile lateral friction and end resistance, the core pile (precast piles, sink steel tube Piles and piles of steel, etc.) have sufficient cross-section of the pile Strength, to satisfy the load demand, High-pressure JG pile and high-core pile are effective combination, pile bearing capacity significantly increased. So the pile has low-cost, economic environment, high bearing capacity of the notable features etc. Tangshan Lanxin Glass project use this pile, Which Successfully resolved the problems of the ordinary pile of prefabricated difficult to penetrate the silty material and silty sand layer, avoid soil extrusion effect, raise the pile bearing capacity, reduce the project cost, economic efficiency and social Obvious benefits.
