Research conclusion: (1)the Biting Pile machine can work in the place of soft clay ground in Shang Hai and the layer rich in water.(2)It is vital to scientifically set the construction technological parameters when it works in different geological condition.(3)The Biting Pile machine works quickly and efficiently with low noise, little quake, without on mud. And so on. The finished the Biting Pile machine is with high quality, good property of waterproofing. The security and civilized construction meet the demand of protecting environment ,which can create nice external image.(4)The use of Biting Pile machine is perpendicular with standard appearance and the waterproof. It's not need to use mud of protection outer protective to the wall, and enlarge machine parameters. When acrossing the soft and richwater earth, it's need not to take other assist measures. The work efficiency and low price provide profit. to deal with the underground obstacles can work out the unsolved problem and consequently obtain a better economic benefit and social benefit.
