TEMPORARY RESTORING METHOD OF VERTICAL SHAFT |
摘要 |
PROBLEM TO BE SOLVED: To suppress subsidence of a temporary buried place without depending on the increase of the thickness of a temporary burying body or a temporary paved surface layer in a temporary restoring method of a vertical shaft excavated in the ground. SOLUTION: Temporary burying bodies 7 formed by enclosing a large number of filling materials 9 for backfilling in place of earth are stacked in the shaft 1 formed in the ground. A partition sheet 3 formed of a flexible non-woven fabric sheet is laid on the temporary burying bodies 7 along the filled surface. The temporary paved surface layer 4 containing road board crushed stones is formed on the partition sheet 3. The partition sheet 3 formed of the non-woven fabric sheet disperses weight load of the temporary paved surface layer 4 and load of a large vehicle transmitted through the temporary paved surface layer 4 in a surface direction while contacting with an upper surface of temporary uneven burying body layers 2 with relatively high conformity. Accordingly, the partition sheet 3 efficiently functions so as to suppress the subsidence. COPYRIGHT: (C)2008,JPO&INPIT
