<p>PROBLEM TO BE SOLVED: To provide a construction method of an underground continuous wall with a V-shape core material which is resistant to an earthquake and safe as a prevention method of diffusion and permeation of chemical dangerous substances, radioactive contamination substances, and contaminated water.SOLUTION: A measuring plant is used for contaminated water or the like. An arrangement includes a device automatically sending pressure-feeding solidification materials from automatic plant to the inside of an enclosure cutoff wall. Admixture is jetted to the contaminated water through a multistep pipe 3 provided in a concrete retaining wall 4 and agitated and mixed. The admixture is accumulated to 1 m under the retaining wall top end and left until being solidified. Then, concrete is installed to the top end using a pump vehicle and is sealed.</p> |
