CONSTRUCTION METHOD OF UNDERGROUND WALL

PURPOSE:To make it possible to economically construct an underground wall even if the thickness of the wall is reduced by making a part deeper than the depth of a specific value of longitudinal moment of the underground wall in an excavated groove hole as the low strength, and making a part shallowe...

description PURPOSE:To make it possible to economically construct an underground wall even if the thickness of the wall is reduced by making a part deeper than the depth of a specific value of longitudinal moment of the underground wall in an excavated groove hole as the low strength, and making a part shallower than the depth as the high strength. CONSTITUTION:A groove hole is excavated from the ground, and an underground wall 10 is constructed by filling the groove hole with hardening sludge to solidify. In that method, a part deeper than the specific depth h) of the groove hole makes as the low strength part A, and a part shallower than the specific depth h) makes as the high strength part B. For the depth h) between the low strength part A and the high strength part B, it is desirable to select the depth of an approximate 0 of longitudinal moment of the underground wall 10. According to the constitution, economic efficiency is not lowered even if the thickness of the underground wall 10 is reduced to increase the concrete strength of the hardening sludge.
