Abstract
PURPOSE: To enable constructing of a ground hardening wall directly in the ground, by a method wherein a high-pressure muddy water nozzle, a pipe for feeding with pressure unhardened concrete, etc. are built in the end of a drilling material.
CONSTITUTION: High-pressure muddy water of 20kg/cm2W150kg/cm2 and pressurized air of 7kg/cm2 are injected through a high-pressure muddy water nozzle 6 and a pressured air nozzle 7 of a rectangle muddy water injection excavator 1 into which the high-pressure muddy water nozzle 6, the pressure air nozzle 7, and a pipe 8 for feeding with pressure unhardened concrete are built, and the excavator 1 is pressed in by excavation as they are discharged through an earth discharge pipe port 9 in combination with a vibration hammer 16. Afterwards, the rectangle muddy water injection excavator 1 is lifted up while unhardened concrete and a cement hardening agent are injected by means of a pressure-feeding pump 5 for unhardened concrete, and this enables the continuous construction of a concrete wall and a soft ground hardening wall directly in the ground.
