CONSTRUCTION OF LATTICED CONTINUOUS UNDERGROUND WALL

摘要

PURPOSE:To construct an underground wall having great joint strength by a method in which a casting with a partition plate is attached to the side ends of reinforcing bar cages to form a preceding panel, the panel point is excavated, the partition plate is drawn out, and concrete is placed to the panel points. CONSTITUTION:In constructing a Y-shaped latticed continuous underground wall at the panel point, a preceding trench 10 is excavated, reinforcing bar cages 11 are set in the trench 10, and concrete 12 is placed to construct a preceding panel. In this case, casings 13 with detachable partition panels 14 are attached to the side ends of the cages 11, and excavation is made circularly where the panel point A is centered. The plates 14 are then drawn out, and reinforcing bar cage 16 is inserted into the round pit 15 and the casings 13. Concrete 18 is then placed. The underground wall having great joint strength can thus be formed.
