\r\n

Les rochem\u00e8tres \u00e0 tige simple ou multiple sont utilis\u00e9s pour mesurer les d\u00e9placements et les d\u00e9formations dans les cul\u00e9es de barrages et de ponts, dans les terrains et les pentes rocheuses, les tunnels et dans les excavations, etc.<\/p>\n<\/div>

\r\n Description <\/h3>\r\n <\/div>
\r\n

Les rocm\u00e8tres permettent de d\u00e9terminer les d\u00e9placements le long de l'axe d'un forage. Un assemblage de tiges est constitu\u00e9 de plusieurs tiges individuelles viss\u00e9es ensemble et install\u00e9es dans un tube de protection en plastique. Les extr\u00e9mit\u00e9s des tiges (ancrages) sont ancr\u00e9es \u00e0 diff\u00e9rentes profondeurs du forage. La t\u00eate fine du rocom\u00e8tre est scell\u00e9e dans le forage. Les ancrages \u00e0 l'extr\u00e9mit\u00e9 des tiges et la t\u00eate du rocom\u00e8tre constituent les points fixes des sections d'essai. Les d\u00e9placements entre ces points fixes sont mesur\u00e9s \u00e0 l'aide d'un d\u00e9flectom\u00e8tre \u00e0 r\u00e9glage manuel (type RM) ou de capteurs de d\u00e9placement \u00e9lectriques (type RMT).<\/p>\n

Les rochem\u00e8tres peuvent \u00eatre install\u00e9s quelle que soit leur position, quelle que soit l'inclinaison, avec des tiges jusqu'\u00e0 80 m de longueur. Ils peuvent \u00eatre \u00e9quip\u00e9s de 1 \u00e0 6 tiges dans un m\u00eame forage (plus de 6 tiges sur demande). Les tiges peuvent avoir des longueurs diff\u00e9rentes selon l'application. Un rochem\u00e8tre multi-tiges permet de localiser la profondeur des d\u00e9placements, ce qui est important, par exemple, pour d\u00e9terminer la profondeur d'installation des ancrages pr\u00e9contraints.<\/p>\n

Les variations de longueur attendues induites par la temp\u00e9rature peuvent \u00eatre compens\u00e9es par l'utilisation de thermom\u00e8tres (t\u00e9l\u00e9thermom\u00e8tre HUGGENBERGER).<\/p>\n<\/div>
