METHOD OF LAYING CRIB BLOCK FOR SLOPE, AND ADJUSTING BENT BLOCK AND JOINING BLOCK USED IN IT

摘要

PROBLEM TO BE SOLVED: To provide a method of laying crib blocks for a slope and the blocks used in it for improving a protecting function, work efficiency and aesthetic appearance by covering a substantially whole slope surface including an odd part which are difficult to be covered by a conventional crib for a slope.;SOLUTION: A number of general-purpose blocks 2, 2a constituting sides of each crib 4 and having predetermined lengths are placed, and their longitudinal ends are joined to each other to form a grating crib 4 on a slope surface 6. In this method of laying the crib blocks, when the odd part is formed at the end of the slope surface 6 in forming the crib 4 by laying only the general-purpose blocks 2, 2a, a plurality of adjusting blocks 1, 1e of one or more kinds having lengths different from these of the general-purpose blocks 2, 2a are used at the end and/or an appropriate position of the slope surface 6. The general-purpose and the adjusting blocks 2, 2a, 1, 1e are arranged at both longitudinal ends of the adjusting blocks 1, 1e as needed, and the ends are joined to each other, and an adjusting crib 5 formed of the adjusting and general-purpose blocks 1, 1e, 2, 2a, or the adjusting blocks 1, 1e is continuously connected to a predetermined crib 4, so that the odd part of the slope surface 6 can be substantially filled.;COPYRIGHT: (C)2009,JPO&INPIT
