摘要： The object of the invention is to provide a method and system for impregnating a liner, simultaneously reducing the risk of a void inside the liner after curing. This object is achieved by an impregnation plant (10) comprising a vacuum lock (16) comprising a housing having an inlet (14) and an outlet and defining an ambient pressure space (15) near the inlet and a low pressure space (24) near the outlet. The pressure spaces are separated by a seal (20) comprising a first and a second sealing element (22, 23), allowing the fibrous liner (12) to be conveyed there between from the inlet (14) towards the outlet. The liner is degassed by compressing it between the first and second sealing elements (22, 23) and is subsequently relaxed in an uncompressed state inside the low pressure space (24). The plant further comprises a vacuum pump communicating with the low pressure space, and an impregnation station in gas-tight communication with the outlet or the vacuum lock (16) and comprising a resin bath (28) for accommodating the liner, a resin reservoir, a nozzle (32), a pipe system (38) and a resin pump (36) for propelling the resin from the resin reservoir via the pipe system (38) and the nozzle (32) into the resin bath (28) in a direction towards the liner.

摘要： The present invention relates to a method and a system for impregnating a tubular liner having a fibrous inner layer and a fluid-irnpermeable outer layer. The method is carried out by means of a conveyor system defining a conveying path monotonously descending from a fourth position via a third and a second position to a first position. At the first position, a resin injector is located. Along the conveying path, one or more constrictions are provided for allowing the liner to assume a flat configuration in which the fibrous inner layer of the liner is contacting an opposite part of the fibrous inner layer of the liner. The liner is positioned on the conveyor system, extending through the conveying path and the one or more constrictions. The liner defines a supply zone extending inside the liner between the first position and the one ore more constrictions and defines an impregnation zone extending inside the liner between the one or more constrictions and the fourth position. The supply zone is filled with resin by using the resin injector, and the resin is allowed to advance in the impregnation zone in a direction opposite the conveying direction of the liner and to reach a steady state position at the fourth position for subjecting the liner to an elevated impregnation pressure between the second and third positions caused by the height difference between the first and second position and the third and fourth position.

摘要： The present invention relates to an apparatus for curing a liner of a pipeline where the liner includes a resin which is curable by exposure to electromagnetic radiation of a specific wavelength or a specific wavelength range. The apparatus comprises a housing defining opposite first and second ends, an outer wall of a substantially cylindrical configuration, and an inner wall defining a substantially unobstructed through-going passage extending longitudinally through the housing between the first and second ends, and further comprises a pair of power supply wires for the supply of electrical power to the apparatus and extending from the first end of the housing, and a plurality of LED's irradiating electromagnetic radiation of the specific wavelength or the specific wavelength range. The plurality of LED's is positioned and substantially evenly distributed at the outer wall of the housing, and is connected through an electronic circuit to the pair of power supply wires. The plurality of LED's is further connected in thermal conductive relationship to heat dissipating elements freely exposed at the inner wall of the housing in the through- going passage of the housing for allowing a stream of cooling fluid to pass through the passage for dissipating heat from the heat dissipating elements and cooling the LED's.

摘要： The invention relates to a method of relining a sewer pipe having an area in need of repair. The sewer pipe is accessed via an access bore having an upper end and a lower end, and an access point at the upper end, and connected to the sewer pipe at a bore-pipe junction at the lower end. The method comprises providing a liner for insert-ing inside the sewer pipe such that the sewer pipe is relined. The method further comprises providing a tube for inserting said liner into said sewer pipe, and everting the liner such that the liner is turned inside out and said inside surface constitutes a temporary outside surface, placing the everted liner inside the tube such that the tube includes the liner and constitutes a tube-liner assembly having a free end, and moving the tube-liner assembly into the access bore with the free end such that the free end of the tube-liner assembly extends into said sewer pipe, inverting the tube-liner assembly when the free end is at bore-pipe junction such that the liner is placed with the outside surface facing the sewer pipe and covering the area in need of repair.
