Dispositif (11) et procédé améliorés permettant de créer un revêtement interne dans un trou de forage. Une bande enroulée autour d'un mandrin (4) de manière à former une spirale à recouvrement est transférée sur la paroi du trou tout en maintenant le rapport bord à bord de la bande enroulée en spirale (21) depuis le mandrin (4) jusqu'à la paroi du trou. On applique un adhésif sur la surface de la bande pendant son enroulement sur le mandrin (4). L'invention permet d'obtenir un nouveau trou pourvu d'un mince revêtement résistant à la corrosion sur une partie déterminée de sa longueur; ce revêtement, qui est essentiellement hermétique à une pression interne ou externe et ne présente pas de fuites, permet d'utiliser le trou à nouveau. | ||||||
213 | VORRICHTUNG ZUM AUSFÜLLEN UND VERLEIMEN VON VERTIEFUNGEN ALLER ART IN EINER NICHTBEGEHBAREN ROHRLEITUNG | EP85900626.4 | 1985-02-13 | EP0211825B1 | 1988-04-27 | HIMMLER, Erich |
The device consists of a mastic material-filled pipe (27) set in a cylinder (24) which is revolvable around its longitudinal axis and secured there against displacement by means of locks (30). Inside the pipe (27) is a piston (31), which is acted upon by a conduit (33) with compressed air. On the free end of the pipe is a mastic device (41) which is locked to the pipe. The piston (31) forces the material out of the pipe into the mastic device, which is revolvable together with the pipe around longitudinal axis thereof. Once the mastic device (41) has been fully emptied, it is removed from the pipe (27) and the latter is separated from the cylinder (24). The empty pipe is replaced by a full pipe and the mastic device is again attached to the latter. In this way the device is again ready for use within a short time. | ||||||

215 | Pipe sealing apparatus and jack | EP82301329.7 | 1982-03-16 | EP0060715A1 | 1982-09-22 | Maimets, Lembit |
Pipe sealing apparatus and a jack for operating the sealing apparatus to effect repairs in sewer pipes and the like are disclosed. The sealing apparatus comprises a collapsible pipeliner (16,18,20,22) constructed in a plurality of arcuate segments that define a closed loop which can be moved from a collapsed state in which the loop can be located in a damaged pipe to an erect state in which the loop defines a rigid pipeliner with a cylindrical outer surface. A compressible sealing material such as urethane foam is secured to the segments so that the sealing material covers the cylindrical outer surface when the loop is moved into the erect state. When the pipeliner is erected the sealing material is compressed between the cylindrical outer surface of the erected pipeliner and a damaged inner surface of the pipe to provide a fluid-tight seal. The pipeliner can be erected by expanding the closed loop vertically and thereafter horizontally until the loop assumes an oversized state from which the loop is biased to move into a locked- erect state of relatively smaller dimension. A hydraulically operated jack (30) for expanding the loop is described. |
