A MODULAR BLOCK FOR FILLING UNDERGROUND BASINS AND BASIN PRODUCED WITH THESE MODULAR BLOCKS

摘要

The block made of plastic material (1) for filling underground basins (I) for storing rainwater or river water comprises a first plurality of hollow truncated-pyramid shaped bodies (3A), extending from a first side of a median plane (M) of the block and a second plurality of hollow truncated-pyramid shaped bodies (3B), extending from a second side of the median plane. The truncated-pyramid shaped bodies (3A, 3B) are configured to mutually superimpose the blocks with the smaller bases of the truncated-pyramid shaped bodies of one block resting on the smaller bases (5) of an adjacent block. Openings in the walls of the truncated-pyramid shaped bodies (3A, 3B) place the inner volumes of the truncated-pyramid shaped bodies (3A, 3B) of mutually superimposed blocks (1) in fluid communication in the position with maximum overall dimensions.
