Problems solved by technology

[0005] Due to the rather long hardening time of at least 12 hours for the adhesive used, it takes a lot of time to repair large-scale damages with known devices, which may for example be over the entire length of a vertically extending weld seam extend

Embodiment Construction

[0023] figure 1 The device according to the invention is shown in a starting position in a water-filled pool 2 of a nuclear reactor installation, the first and second slides not shown. The device comprises a support frame 4 held in a support 3 resting on the edge of the pool for a guide system 6 extending in the longitudinal direction 5 and consisting of two mutually parallel guide rails 6a, b, the guide system It is always assembled from a plurality of segments 8 which are detachably connected to each other. A plurality of suction cups 10 are arranged on the guide system 6 or on the guide rails 6 a, b, which can be under-pressurized via a suction line not shown in the figure and in this way connect the guide system 6 to that in the example Vertically extending side walls 12 are fixed vertically to the side walls at a distance. The walls of the pool 2 (side walls 12 and bottom) are provided with linings 14 made of steel plates welded to each other.

Abstract

The invention relates to a device for repairing damaged sites in the submerged wall region of a container or pool, in particular in the wall region of a pool of a nuclear reactor facility, comprising a device along the side wall (12) with The side wall is spaced apart from a guide system ( 6 ) which can be mounted at a distance and can be fixed on the side wall. At least one first slide (20) guided thereon and movable in the longitudinal direction (5) of the guide system (6) is placed on the guide system (6), on which a movable Ground-supported receptacle (30) for a repair coating (22) that can be attached with an adhesive surface to the wall region containing the damaged site, wherein on the first slide (20) At least one suction cup is provided which can rest against the side wall (12) and is connected to the suction line.

Description

technical field [0001] The present invention relates to a device for repairing damaged points in the submerged wall region of a container or a pond, in particular in the wall region of a pond of a nuclear reactor installation, as is known, for example, from DE 10 2008 014 544 A1. Furthermore, the invention also relates to a method for repairing such damaged sites. Background technique [0002] The walls (side walls and bottom) of water-filled pools of nuclear reactor installations, such as reactor pits or fuel element storage pools, are provided with linings made of steel plates welded to one another. The welds where the steel plates are welded to each other or to the base are susceptible to chlorine-induced stress corrosion due to the mechanical stress that is unavoidable during welding, and cracks may gradually appear. To prevent pool water from escaping through such cracks into the concrete wall, these cracks must be sealed. In order to ensure adequate shielding of main...
