Title (EN) A METHOD OF PLACING A WEB
(FR) PROCEDE DE MISE EN PLACE D"UNE GARNITURE EN BANDE
Abstract: front page image
(EN)During the construction of an entrenchment below the ground water level in the neighbourhood of nature area"s, one is not allowed to drain the entrenchment and yet it has to be ensured that a reliable watertight web is positioned on the floor of that entrenchment. The invention has solved this problem by wrapping the web (v) around a roll (3) floating in the entrenchment (4), and subsequently navigating that roll (3) to the beginning of the entrenchment (4) after which unwinding and attachment of the web (v) takes place. An important feature of the invention is that after positioning of the roll unwinding takes place by pumping water from the entrenchment at the location where the web still has to be applied, to the location between the initial edge of the web and the core (fig.3).
(FR)Pendant la construction d"une tranchee en dessous du niveau de l"eau dans le voisinage d"une zone naturelle il n"est pas permis de drainer la tranchee et il est necessaire qu"une garniture impermeable a l"eau soit mise en place sur le fond de cette tranchee. L"invention resoud ce probleme en enroulant cette garniture (v) autour d"un rouleau (3) flottant dans la tranchee (4) et en faisant naviguer ce rouleau (3) vers le debut de la tranchee (4), apres quoi le deroulement et la fixation de la garniture (v) sont effectues. Une particularite importante de l"invention reside dans le fait qu"apres la mise en position du rouleau, le deroulement se fait en pompant de l"eau depuis la tranchee a l"endroit ou la garniture doit encore etre appliquee, vers le point situe entre le bord initial de la garniture et le noyau.
