Construction of revetment work and block therefor

Abstract

Abstract PURPOSE:To quickly and easily form a revetment work by a method in which plural kinds of blocks having the same bottom structures are combined and set according to a predetermined pattern selected on the roughness coefficients of river. CONSTITUTION:Standard blocks 10 of the same bottom structures are combined with blocks 11 having projections of fixed dimensions for determining plural kinds of patterns. In forming a revetment work 1 to weaken the energy of the downstream of a dam 4, a roughness coefficient (n) is obtained from the max. flow and slope of river. A pattern matching the coefficient (n) is selected from the predetermined patterns, and according to the pattern the blocks 10 and 11 are set and fixed. The revetment work 1 matching the roughness coefficient of a river can thus be easily and quickly constructed.
