The present invention relates to a method for constructing a wall (bearing wall) by extending a basement of a building and, more specifically, to an underground wall construction method for extending an underground parking lot. The present invention can obtain a partial work space for constructing a retaining wall and support and reinforce a structure by using a steel pipe, a pillar, and a buttress, so that the construction can be done conveniently while obtaining the stability of an existing building. The present invention also reduces construction periods and construction costs so that the investment costs can be reduced when a structure is remodeled.
