Long auger drilling rig is a new product which is based on domestic and international advanced technology. It is a construction foundation equipment, which is not only applied for piling foundation in housing construction, but also for the traffic, energy engineering and soft base enhance, etc., Currently CFG is listed as national new method and national construction standard. lt can finish the pile in one time, perfuse pile at site and also finish the operation of placing the steel cage. Efficiency, high quality and low cost are the main advantages of this machine. Simple structure ensures flexible move, easy operation and convenience maintenance. It is applicable for clay soil, silt and fill, etc. It can pile in different complicated geological conditions such as soft soil, draft sand formation, sand and gravel layers, with groundwater and so on. Besides, it can construct cast-in-place pile, hi-pressure grouting-pile, grouting ultra-fluidized pile, CFG composite pile, pedestal pile and other ways. There is no vibration, noise and pollution during construction. It' s an excellent equipment for infrastructure construction.
