Description

468 562 10 15 20 25 30 35 2 thereby ensuring that the drain 1 has a sufficient slope along its length for the water to be removed. For the casting of the concrete mass 4, a casting frame plate 6 can be used, which, however, is removed after the installation has been completed. A bitumen mass 3 is laid on the concrete mass 4 and the drain grid ä is placed on top of the mass 3 with its downwardly projecting legs inside the drain 1, however, the flanges 7 of the drain grid 2 rest on top of the bitumen mass. Through openings 5 in the flanges 7, bitumen mass is filled until the upper surface of the drain grid 2 is substantially aligned with the surrounding surfaces. Thereafter, the drain grate 2 is rolled over until it is aligned with the surrounding surfaces, whereby excess bitumen mass 3 is forced through the openings 5 and then removed from the surface of the drain grate 2. The described method according to the present invention provides a simple and very fast way to achieve an alignment of the drain grid 2 in relation to the surrounding surfaces, which grid can be adjusted to a lower or higher level due to abrasion of the surrounding surfaces or possible application of new asphalt.

If the surrounding surface wears down and the drain grate 2 has to be lowered, the drain grate 2 is heated to a temperature of around 100 ° C, whereby the bitumen mass 3 is simultaneously heated. Thereafter, the drain grate 2 is overturned until its upper surface is level with the surroundings, whereby the bitumen mass 3 is pressed through the openings 5 until the level alignment is reached. excess bitumen mass is then removed.

To lift the drain grid 2, such as to achieve alignment with the upper surface of new asphalt on surrounding surfaces, the drain grid 2 is heated in the same way until the connection between the bitumen mass 3 and the underside of the flanges 7 is loosened. Then the drain grate 2 is raised to the desired level, bitumen masses are refilled via the openings 5 until the open space between the surface of the bitumen mass 3 and the underside of the flanges is filled. The drain grate 2 is then rolled over again until the upper surface is aligned with the surroundings, and any excess bitumen mass is removed. * enligt 10 15 20 25 30 35 468 562 3 The methods of the present invention provide an opportunity for simple and rapid adjustment of the upper surface of the drain grid 2 to align it with surrounding surfaces by raising or lowering the drain grid and thereby achieving alignment with surrounding surfaces. .

4 8 562 5 10 15 20 25 30 35 PATENT REQUIREMENTS A method of lowering a drain grid relative to an embedded drain for receiving surface water from surrounding surfaces, characterized in that the grid (2) is heated to a temperature of approximately 100 ° C so that bitumen mass (3) between the grid and the drain are simultaneously heated to lower the grid (2) by means of a downward force until the grid is level with the surrounding surfaces, whereby excess bitumen mass (3) is led out through openings (5) in flanges ( 7) at the grille (2) and then removed. Method of lifting a drain grid relative to an embedded drain for receiving surface water from surrounding surfaces, characterized in that the grid (2) is heated to such an extent that the grid is released from the bitumen mass (3) between the grid and the drain, that the grid (2) is raised to a desired level, that the space between the grid (2) and the upper surface of the bitumen mass (3) is filled with additional bitumen mass, and that the grid (2) is overturned until alignment with the surrounding surfaces is achieved, whereby any excess bitumen mass, forced up through openings (5) in flanges (7) of the grille, is removed.
