PURPOSE:To raise the integrity and water stopping property of an underground continuous wall by a method in which a well having opened upper and lower ends is penetrated into the ground between master piles and concrete is placed into the space between the well and the master pile and also into the inside of the well. CONSTITUTION:Master piles 1 are penetrated into the ground at a given interval, and a well 3 whose upper and lower ends are opened is set between the piles 1. While excavating the bottom of the well 3, the well 3 is penetrated to a given depth into the ground, a reinforcing bar cage is set in the well 3, and concrete is placed. Concrete is also placed into the space formed by the guide groove 11 of the piles 1 and the recession of the end of the well 3. The integrity and the water stopping property of the underground continuous wall can thus be enhanced.
