| Abstract:According to the years construction experience, when the technology of pump pressure CFG pile in continuous auger drilling pipe is applied in the stratum of saturated clay in Zhengzhou area, a series of environmental problems would come forth, such as ground settlement around piles and adjacent buildings, pavement cracking and pipeline dislocation. By the comprehensive study on the mechanism of environmental problems caused by construction of pump pressure CFG pile in continuous auger drilling pipe, the countermeasures are put forward, and the adaptability evaluation on this technology in saturated silty soil is made. |
