PROBLEM TO BE SOLVED: To facilitate piling-up construction of natural stones and, at the same time, construct a stable and firm civil engineering structure even in the case where such piling-up construction of natural stones is carried out. ;SOLUTION: The basic end of a bar-shaped member 4 is combined with a natural stone 2, and a civil engineering structure construction stone 1 having a curl section 15 as a frictional force increasing device on the front end of the bar-shaped member 4 is prepared. A plurality of civil engineering structure construction stones 1 are used to successively pile up the natural stones 2, at the same time, the bar-shaped members 4 are parallel arranged, the bar- shaped members 4 are embedded with crushed stones 13, etc., to ensure strong frictional force (interlocking force) based on the crushed stones 13, etc., and curl section 15, etc.;COPYRIGHT: (C)2000,JPO
