CIVIL ENGINEERED STRUCTURE, PACKING LAYER RETAINER FOR CIVIL ENGINEERED STRUCTURE, AND METHOD OF CONSTRUCTING CIVIL ENGINEERED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a revetment which minimizes degradation in uniting capability of a backfilling material layer to a backfilling concrete wall surface even if the thickness of the backfilling material layer must be reduced.;SOLUTION: The revetment 1 is constructed by arranging the backfilling material layer 26 and a layer of natural stones 24 on a surface of the inclined backfilling concrete wall surface 8a in this order in a direction separating from the backfilling concrete wall surface 8a. Each natural stone 24 is mounted on the backfilling material layer 26 via mounting anchors 25, and the backfilling material layer 26 is held on a backfilling concrete wall 8 by packing retainers 13. Thus the uniting capability of the backfilling material layer 26 to the backfilling concrete wall 8 is enhanced, and therefore even if the thickness of the backfilling material layer 26 must be reduced, degradation in the uniting capability of the backfilling material layer 26 to the backfilling concrete wall 8 is minimized, to thereby enhance the reliability of the backfilling material layer 26 as a mounting object of the natural stones 24.;COPYRIGHT: (C)2006,JPO&NCIPI
