METHOD AND DEVICE FOR LAYING UNDERGROUND CONTINUOUS WALLS

摘要

An underground continuous wall building method and apparatus in which a chain cutter 2 provided with excavation blades is obliquely mounted on a running carriage 1; slanting continuous trenches G1, G2 are excavated by moving the running carriage 1 in a transverse direction while rotating the cutter 2 wit the cutter 2 obliquely placed in the ground; and a water cutoff material is poured into the excavated continuous trenches G1, G2 and solidified therein to build slanting continuous walls R1, R2 in the ground. <IMAGE>
