PURPOSE:To construct a strong continuous underground wall by a method in which an intermediate panel is placed on a panel temporarily supported on an already-set panel, both the nanels are joined and brought down by introducing a stress into them, and an upper panel is orderly joined with them by introducing a stress into them. CONSTITUTION:An underground wall panel IL is hung down in an excavated trench T and brought down under the guidance of the steel pipe 2A' of an already-set underground wall panel IU'. The hanging pin 7 of the panel IL is received by a support base 15 on a guide wall 14, and the panel IL is temporarily supported. Then, an intermediate underground wall panel IM is placed on the panel IL, a PC bar is inserted into the panels IL and IM through their through holes 4, upper and lower PC steel bars 16 are connected with a coupler 17, and they are clamped with a nut 18 and a stress is introduced into them. The hanging pin 7 is removed, and the integrally combined panels IL and IM are brought down. The panel IM is temporarily supported, an upper panel is taken in, a stress is introduced into the panel, the panel is connected with the panel IM, and then the pin is removed. These processes are orderly repeated to construct a continuous underground wall. |
