Method and apparatus for forming piles in-situ |
摘要 |
The invention provides a method for making piles and apparatus for practising the method. The piles may be used to support the foundation of a structure, such as a building. The method draws a soil displacer on a shaft down through a body of soil by turning a screw at the lower end of the shaft. The soil displacer forces soil out of a cylindrical region around the shaft. The cylindrical region is filled with grout to encapsulate and strengthen the shaft. The grout may be fed by gravity from a bath of grout around the shaft. The soil displacer has a diameter smaller than a diameter of the screw and may be a disk extending in a plane generally perpendicular to the shaft.
