| 摘要 |
The invention relates to a semi-open covering structure (1) for partially covering a traffic lane (10), particularly for automobile traffic, which extends along the ground (5) along a line (L), and which includes: a plurality of load-bearing structures (20A, 20B, 20C) distributed along the line, extending from a first ground portion (47) located on one side of the traffic lane up to a second ground portion (49) located on the other side; and a plurality of troughs (25, 25A, 25B) suitable for receiving topsoil and plants, each trough resting on or being attached onto at least one load-bearing structure. The troughs and load-bearing structures form a covering (35) defining openings that allow air to flow among the troughs, from an inner space (40) to the atmosphere (45) surrounding the covering structure. The troughs and the load-bearing structures form at least one screen (74) capable of inhibiting the propagation (F1, F2) of sound waves horizontal and substantially orthogonal to the line, from the inner space to the atmosphere. The screen extends along the line between at least two consecutive load-bearing structures. |
