<p>The barrier (1) comprises supports each comprising: - an uphill post (7) having a base articulated to the ground (2) and a top connected to an uphill anchor point (9) by an upper uphill stay (18) and an uphill brake (10); - a downhill post (8) having a top articulated to and suspended from the top of the uphill post and a base connected to the uphill anchor point by a lower uphill stay (22). The endmost downhill posts are additionally connected to a lateral anchor point (11) by lower (24) and upper (23) lateral stays and a lateral brake (12). Nets (4) are slung between the downhill posts across the slope. The supports adjacent to the net loaded with landslide open up like a pair of compasses then pivot toward one another, the downhill posts remain parallel to one another.</p> |
