Application Of CFG Pile Composite Foundation In Baotou Area

With the development of city in our country, the construction landhas becomemore tense, more and more high-rise building, became the dominant force in the new city construction, the buildings is becoming higher and higher, the upper load corresponding also more and more big, the bearing capacity of foundation put forward higher requirements, foundation processing method of ordinary,now can not meet the requirementsof high bearing capacity, while the bearing capacity of pile foundation can provide higher, but itscost is higher, and the longer duration, which requires a new wayof foundation treatment and replace. CFG pile composite foundation,is only developed in recent years, for the foundation treatment method of strengthening soft soil foundation, its constructionprocess is simple, construction materials more environmentally friendly, the construction cost is low, the reinforcement treatmenteffect is good and so many advantages, in our country manyprovinces and cities have received a promotion and application ofuniversal, and achieved economic and social benefit is good.This paper briefly expounds the importance of ground treatment technique, summarizes some basic concepts, and classification ofcomposite foundation reinforcement principle, through comparative analysis points out the difference between the reinforcementmethod of CFG pile composite foundation treatment method and the traditional pilefoundation, and summarizes some advantages of CFG pile foundation treatment method, analyzes the basic method of CFG pile load test of composite foundation, introduced in the construction process of quality testing items of CFG pile composite foundation; with specific data showed it in the economic, social benefits, superiority in the construction period and so on; of composite foundation with CFG pile and the formation of regional representative of Baotou area are summarized and analyzed, and provides reference for further promotion and application of CFG pile foundation processing technology; finally, in contact with a large number of engineering practice, the engineering experience,the application of CFG pile composite foundation in the construction process of choice, in the indwelling length of pile length in theapplication and protection playing order and other aspects of thein-depth analysis and discussion, summarized some relatively mature engineering experience. The CFG pile in Baotou and other similar stratigraphy in the future application and developmentprovides technical guidance andreference.
