RESOURCES-SAVING TYPE CONTINUOUS SHEATHING WORK

摘要

PURPOSE:To obtain a sheathing wall having a high safeness and a high water shielding property by a method in which a sheathing wall having a core material made of a friction-cut steel material is constructed, the underground outer wall of the structure is built up on the inside, the core material is drawn out, and then a grout, e.g., cement mortar, etc., is injected into the space formed. CONSTITUTION:After the ground is excavated, an interlocking box 1 is set, and then concrete 3 is placed. While the concrete 3 is unset, a steel material 4, e.g., H-shaped steel, etc., subjected to a friction cutting treatment is hung down. After the concrete 3 has set properly, the interlocking box 1 is pulled out to construct the unit of a continuous wall. The same operations are repeated to construct a sheathing wall 5. The ground surrounded by the sheathing wall is excavated, the underground outer wall 6 of the structure is constructed, the steel material 4 is drawn out, and then a solidifiable grout 7, e.g., cement mortar, etc., is injected into the space (b) formed after drawing out the steel material 4 in the sheathing wall to repair the sectional damage in the space portion.
