Abstract

PURPOSE:To prevent the entrainment of sand to a water permeating pipe when extracting the water permeating pipe by building the water permeating pipe, inserting a sand hold-down shaft and charging sand when creating the sand pile. CONSTITUTION:A hollow pipe 2 to which a spiral blade 1 is mounted is excavated into the ground while being turned, and the water permeating pipe 8 to which slits 9 are formed is isnerted into the hollow pipe 2. The hollow pipe 2 is rotated, and the hollow pipe 2 is upward extracted while consolidating the circumference of the hollow pipe 2. Water 11 in the ground is discharged onto the ground through the water permeating pipe 8, and the sand hold-down shaft 12 is inserted into the water permeating pipe 8. A step shaft or a screw shaft is used as the shaft 12. The sand 14 for creating the sand pile is charged into the water permeating pipe 8, and the water permeating pipe 8 is extracted onto the ground. Lastly, the shaft 12 is extracted onto the ground, and the sand pile 16 is formed.
