Abstract

PURPOSE:To effectively settle a caisson by a method in which an outer cylinder having plural screw conveyers inside is air-tightly and piercingly attached to the upper slab of a compressed air work chamber for a caisson and excavated soil an sand are continuously pulled up and discharged. CONSTITUTION:Excavated soil and sand from the bottom ground of a compressed air work chamber 2 for a caisson 1 is charged into an outer cylinder 8 from the lower charging port 6 of the outer cylinder 8 of a screw conveyer 4, while screws 9 and 9' are turned through both grears 11 and 11' by a drive motor 12. Screws 11 and 11' are turned in mutually oposite directions, the soil and sand put on spiral blades 13 and 13' are moved upwardly and discharged to the outside from a discharge port. The soil and sand are put on a belt conveyer 3 and sent to a soil and sand dumping site. As the soil and sand are excavated in the compressed air work chamber 2, the caisson 1 settles by itself into the ground G.
