<p>A noise-absorbing greenary-carrying (12) structure makes use of worn tyres (7) which are divided, by cuts extending from the central opening of the tyre into mutually adjacent sectors (9), the concave sides of which face towards a carrying frame (2) on which the said sectors (9) are fixed in horizontal layers. The hollow spaces inside the sidewalls of the tyres, but also inside the central openings in the tyres, are filled with earth (13) suitable for the growth of greenary (12), which can preferably pass through openings (14) provided in the upper sidewalls (20) of the tyres (Fig. 1).</p> |
