Title
(EN) SAFETY MAT FOR USE IN PROTECTION OF WATERWASHED AREAS AGAINST EROSION AND/OR UNDERMINING
(FR) TAPIS DE SECURITE UTILISE POUR PROTEGER DES ZONES AU CONTACT DE L"EAU CONTRE L"EROSION ET/OU L"AFFOUILLEMENT
Abstract
(EN) A safety mat (1) for protection against erosion and/ or undermining consisting of a number of parallel tubular members (2) containing a filling material (4) and being inter-connected by cross-binding ribbons (3) placed at right angles to the tubular members. As filling material (4) is used a granulated material of an average density of at least 1,6 kg/dm3, and the tubular members (2) have a degree of filling of substantially 75%. Using a relatively heavy filling material that is introduced relatively loosely a mat is obtained having great flexibility, being able, therefore, to lie close up against even a domed bottom. The danger for undermining by washing away is therefore greatly reduced.
(FR) Un tapis de securite (1) de protection contre l"erosion et/ou l"affouillement comprend plusieurs organes tubulaires paralleles (2) contenant un materiau de remplissage (4) et relies entre eux par des rubans de reticulation (3) places a angles droits par rapport aux organes tubulaires et autour de ceux-ci. On utilise comme materiau de remplissage (4) un materiau granulaire d"une densite moyenne d"au moins 1,6 kg/dm3, et les organes tubulaires (2) ont un degre de remplissage sensiblement egal a 75%. En utilisant un materiau de remplissage relativement lourd qui est introduit d"une maniere relativement non tassee, on obtient un tapis ayant une grande flexibilite, et donc capable de reposer sur un fond ayant meme une forme de dome. Le danger d"affouillement par action de l"eau est par consequent reduit de maniere considerable.
