Design and construction of pile-sinking preventive measures of static pressure piles

The soil squeezing effects caused by the static pressure piles in saturated soft clay ground such as Yangtze River delta will bring severe negative influence on the environment including the soils around the piles, the nearby building and so on. Based on an example of static pressure piles in Shanghai, some pile-sinking preventive measures are proposed in order to avoid the soil squeezing effects on the roads, pipelines and buildings. Meanwhile, the process of pile-sinking is plotted carefully and the informatization monitoring is employed in the process. The monitoring results show that the preventive measures are useful, the deformations of the roads, pipelines and buildings are controllable, and there aren’t any soil squeezing effects.
