PURPOSE:To completely clean a partitioning mesh panel, by a method wherein water is injected from an injection pipe against a partitioning mesh panel mounted between the internal plates of a partition member to disperse slime adhered thereto toward the side opposite to the injection pipe, and the slime is sucked through a suction pipe for removal. CONSTITUTION:A partitioning mesh plate 8, bent in zigzag by support levers 6 to form projections and recesses, is located between internal plates 4 of a partition member 2 of an underground continuous wall. Prior to concreting, water is injected from an injection pipe 19 gradually lowered, slime adhered to the partitioning mesh plate 8 is dispersed toward the side opposite to the pipe, and the slime is sucked through a suction pipe 20 for removal. This enables complete cleaning of the partitioning mesh plate 8, and enables unit wall bodies to be engaged with each other after concrete is placed to reliably form the wall bodies integrally with each other. |
