Abstract
PURPOSE: To prevent the sand ground under foundation piles and a footing from liquefaction as well as to seek the security of bearing force by a method wherein drain piles composed of a good permeable material such as pebbles, fine stones, sludge, etc. are driven into the ground around the foundation piles.
CONSTITUTION: Drain piles 5 are arranged in a proper interval and driven in the ground along almost the all circumference of an outer peripheral wall side of a footing to be constructed at the upper part of a foundation pile 1. In the formation of the drain pile 5, a casing 10 wherein a cover 11 freely opening and closing which closes during a driving in and opens during the pulling out in suspending with its own weight is equipped at the point part is driven into a given place of the ground by means of a vibration generator 12 such as a vibrohammer, etc. After a given length of the casing is driven into the ground, while the materials for formation of a drain pile such as pebbels, fine stones, sludge, metals and synthetic resin particle on pieces are being cast into the casing 10, the casing 10 is pulled out to form the drain pile 5 in the ground.
