BEDROCK EXCAVATION BUCKETS AND UNDERGROUND CURTAIN WALL CONSTRUCTION METHOD USING THE SAME

摘要

PURPOSE: An underground barrier wall using a bedrock excavating bucket is provided to install a barrier wall to prevent a lateral flow of underground water in underground by using a bedrock excavating bucket capable of excavating the underground bedrock. CONSTITUTION: A method for installing an underground barrier wall using a bedrock excavating is as follows. The makeup of a target ground is researched and a pond, a cement silo, a bentonite storage tank, and various kinds of equipment are installed around the target ground so that preparation for installing an underground barrier wall is performed. A trench(T) is formed by excavating the target ground at a constant width and depth with a bedrock excavation bucket. The trench is filled with bentonite(B). The bentonite is filled with a backfilling material consisting of a cement mixture(C) or a soil mixture(S). The backfilling material is solidified at predetermined time.
