Title:
TEMPORARY PILE DRIVING METHOD
Document Type and Number:
Japanese Patent JP2017008632
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a temporary pile driving method capable of inexpensively obtaining stabilization fluid and thereby reducing a construction cost.SOLUTION: In a pile driving method to excavate a vertical hole in the ground with an auger and drive a temporary pile by injecting stabilization fluid into the vertical hole, the stabilization fluid is produced from pulverized concrete sludge, bentonite and water. The pulverized concrete sludge is produced through a recovery process made up of: a slurry production step to produce slurry by mixing remained concrete or returned concrete with water; a separation step to obtain sludge water by removing gravel, sand and fine sand from the slurry; a dehydration step to obtain dehydrated cake by dehydrating the sludge water; and a pulverizing and drying step to pulverize and dry the dehydrated cake by feeding the same in a predetermined rotary drum into which hot blast is injected.SELECTED DRAWING: Figure 1
