Abstract

PURPOSE: To enable rapid coping with stress increasing during the construction work and also reinforcing and correcting work for deformation by introducing tensional members in advance into the sectional area of a wall body.
CONSTITUTION: Plural tensional members are beforehand arranged inside the body of a continuous wall underground. One tensional member 2a is tensed during a process in which the back side of the continuous wall 1 is digged, waling 5 is placed, and a sheathing member 6 is placed, in which it is so designed that prestress is introduced into the side where bending and tension are applied in the neighborhood of the maximum point of bending moment A applying on the wall body at the time when bending and tension are applied. The other tensional member 2b which is used later is tensed during the process in which pit excavation is finished and foundation slab 7, etc., are gradually constructed while demounting waling 5, sheathing member 6, etc., in such a way that prestress is introduced into the side where bending tension are applied in the neighborhood of the maximum poing of bending moments C and D. Thus, because tension is given to the tensional members to cope with stress increasing during the construction work, the number of iron bars necessary for stress all the time can be reduced.
