Abstract
PURPOSE: To shorten the period of construction work by discharging soil from a caisson with lesser hands and low installation const by a method in which excavated soil and sand are mixed with an appropriate amount of water to a slurry in a work room and then sucked and discharged continuously to the outside of the caisson through a soil-discharge pipe.
CONSTITUTION: Soil and sand excavated by an excavator, etc., are piled in the working range of a grab 20 by means of a bulldozer 2 in a work room 1, and then the soil and sand are grasped by the grab 20, charged into a slurry tank 11 by a hoist 19, and then stirred with an appropriate amount of water supplied from a water supply pipe 17 by means of a mixer 12. Then, the slurried soil and sand are sucked up through the mixer 12 and then discharged to a classifier 15 through a soil discharge pipe 13, where the slurried soil and sand are separated into soil, sand and water by the centrifugal separation mechanism of a device 15, the soil and sand are discharged to a truck, etc., and the water is flowed into a circulating tank 16 and supplied again into the tank 11 through the water supply pipe 17.
