PURPOSE: To construct a basement as much closer to its adjacent boundary as possible by a method in which a retaining wall is constructed by fitting sheathing walls of an L-shaped cross section into concaved portions orderly formed during the construction work.
CONSTITUTION: A side wall A is first formed at angles of 45° from the upper edge 3 to the bottom 4 of an excavated trench. Then, excavation is made vertically from the upper edge 3 to half the height of the side wall A to form the first excavated portion, push plates are applied through struts 7a and 7b on the walls of the first excavated porton for reinforcing, and excavation is made vertically from the wall face to the bottom 4 of the first excavated portion to form a concaved portion. Then, a sheathing wall 11 consisting of a base plate and a retaining wall plate, having an L-shaped cross section, is fitted into the concaved portion. In the same way, the sheating walls 11 are fitted into concaved portions orderly formed in the side wall A to construct a retaining wall.
