CIVIL ENGINEERING STRUCTURE, UNIT FOR CIVIL ENGINEERING STRUCTURE AND LIFTING CARRYING TOOL

摘要

PROBLEM TO BE SOLVED: To reduce a concrete filling quantity while securing the predetermined installation strength of a protective wall to a construction surface.;SOLUTION: The protective wall 23 is formed by interposing a concrete layer 22 between a back face side concrete plate 9 and a surface side concrete plate 8 in a unit 7 for respective civil engineering structures. A clearance 21 is formed between the adjacent back face side concrete plates 9, and a part of the concrete layer 22 is intruded into a back-filling layer 5 via the clearance 21, and a part of its concrete layer 22 is engaged with a packing stone 6 in the back-filling layer 5. Thus, the concrete filling quantity for forming the protective wall 23 is reduced on the basis of securing the predetermined installation strength by enhancing an integrating force of the protective wall 23 to the back-filling layer 5.;COPYRIGHT: (C)2007,JPO&INPIT
