The filling pile department is refers to, in the project scene through the mechanical drill hole, the steel pipe pushes methods and so on earth or manpower excavation forms the pile hole in the foundation soil, and lays aside the pile which in among them the reinforcing cage, the irrigation concretes make, according to becomes the hole method to be different, the filling pile may divide into the settling tube filling pile, the drill hole filling pile and digs the hole filling pile and so on several kinds. Drills a hole the filling pile is according to becomes one kind of pile which the pile method classification defines. The filling pile earliest more than 100 year ago in 1893, because of the industry development as well as the population growth, the high-rise construction increased unceasingly, but because many city's ground conditions were quite bad, could not withstand the pressure which directly transmitted by the high-rise construction, the surface following has the thickness very big soft soil or the medium intensity clay level, the construction high-rise construction like still continued to use the friction pile which at that time used in common, had the very big subsidence inevitably. Therefore engineers used for reference have dug a well the technical invention to dig in the hole to construct the reinforced concrete artificially to become the pile. Therefore afterward 50 years later, namely developed in the early-1940s along with the high efficiency drill hole machines and tools first is published successfully in the US, after World War II, the world was specially the European and American developed country economic resurgence and the development, at this point, changes with each new day along with the science and technology the development, drilled a hole the filling pile in high-level, in the ultrahigh layer building and the heavy construction is widely applied. Certainly, in our country, drilled a hole the filling pile design and the construction level also obtained the considerable development.
