<p>PURPOSE: A method and a device for producing a trench wall element is provided to determine the position of a trench and a removal device using the rope point position of two vertical spaces confirmed by measuring the angle and distance. CONSTITUTION: A method for producing a trench wall element comprises the following steps: producing a trench on the ground by removing ground materials using a removal device; inserting a hardening medium in the trench; and elongating two or more ropes between the removal device and a carrier device to separately confirm the positions of two or more vertical space rope points by measuring the angle and distance using a measurement device. The confirmed position of the rope point is used for determining the position of the removal device on the ground.</p> |
