Abstract:
The present invention relates to an underground wall construction method comprising: a drilling step of consecutively forming a plurality of drill holes (10); a hole expanding member insertion step of consecutively inserting multiple hole expanding members (100) into the plurality of drill holes (10), wherein each hole expanding member has both sides with a front soil blocking plate (110) and a rear soil blocking plate (120) removably coupled to the hole expanding member, wherein lower ends of the front soil blocking plate (110) and the rear soil blocking plate (120) are spaced apart by a predetermined interval; a soil blocking plate support step of supporting the upper end of the front soil blocking plate (110) in a forward direction and the upper end of the rear soil blocking plate (120) in a backward direction; a hole expanding member removing step of removing the hole expanding members (100) in the state where the front soil blocking plates (110) and the rear soil blocking plate (120) are inserted into the holes (10); a reinforcement assembly forming step of forming reinforcement assemblies (200) by assembling reinforcing steel bars onto reinforcement plates (210); a reinforcement assembly insertion step of removing the front soil blocking plates (110) and inserting the reinforcement assemblies (200) into the holes (10) such that the reinforcement plates (210) are placed at the locations of the front soil blocking plates (110); and a concrete placing step of placing concrete (c) in the area between the rear soil blocking plates (120) and the reinforcement plates (210) so as to form a wall. Thus, construction is conveniently performed, and the time and cost of the construction can be reduced.
