Concrete block used for revetment etc.

摘要

PROBLEM TO BE SOLVED: To make a concrete block accommodative to construction of a revetment at a steep slope and construction of a retaining wall for preventing landslide at a steep-sloped mountainside by a method wherein a surface part, a trunk part and a hold part of the block are formed integrally, and the surface part is constructed of a base formed in an appropriate thickness and in a specified geometrical shape designed for adaptability in continuous joining in the lengthwise and the breadthwise directions and a plurality of imitation stones. SOLUTION: A surface part, a trunk part 3 and a hold part 2 are formed integrally by using a form. The surface part is constructed of a base 4 formed in an appropriate thickness and in a specified geometrical shape designed for adaptability in continuous joining in the lengthwise and the breadthwise directions and a plurality of large imitation stones A-D. The large imitation stones A-D are arranged in the designed specified geometrical shape so that each of the large imitation stones A-D comes into contact with two or more sides of the shape while the large imitation stones A-D are made to come into contact with one another. Gaps each in unspecific shape formed in the geormetrical shape by contact arrangement of the large imitation stones A-D are formed likewise in the same shape and the size at the base.
