Definitions

• the present invention is related to a drain for surface water comprising an adjustable drain grating and a method for installing and adjusting the grating subsequent to installing of the drain, according to the preambles of the claims.
• the upper surface of the drain grating may very quickly and easily be adjusted to desired level in relation to the surrounding surfaces and the drain grating also easily and quickly may be adjusted if the level of the surrounding surfaces should be lowered or lifted. This is achieved with the drain and the method according to the present invention as described by the features stated in the claims.
• Fig. 1 a cross section of the drain according to the present invention and Fig. 2 discloses a ground view of the drain grating.
• a concrete mass 4 is arranged on the upper edge surfaces of the drain to achieve a course alignment of the upper surface in relation to the surrounding surface, thereby ensuring that the drain 1 has an adequate gradient along its length for the water to be removed.
• a casting frame board 6 may be used, however removed after completed installation.
• On the concrete mass 4 a bitumen mass 3 is laid and the drain grating 3 is placed upon the mass 3 having its downwards protuding legs in the interior of the drain 1, the flanges 7 of the drain grating 2, however resting on top of the bitumen mass.
• bitumen masses are filled until the upper surface of the drain grating 2 substantially is aligned with the surrounding surfaces. Thereafter the drain grating 2 is rolled until alignment to surrounding surfaces, is achieved excess bitumen mass 3 thereby being pressed through the apertures 5 and subsequently being removed from the surface of the drain grating 2.
• the described method according to the present invention provides a simple and very quickly method to achieve alignment of the drain grating 2 in relation to the surrounding surfaces, which grating may be adjusted to a lower or higher level due to wear of the surrounding surfaces or possibly laying of new asphalt.
• the drain grating 2 is heated to a temperature around 100oC, the bitumen masses 3 thereby simultaneously being heated. Thereafter the drain grating 2 is rolled down until its upper surface is aligned with the surroundings, bitumen masses 3 thereby being pressed through the apertures 5 until alignment is achieved. Excess bitumen masses thereafter are removed.
• the drain grating 2 To lift the drain grating 2, such as to achieve alignment of the upper surface of new asphalt on surrounding surfaces, the drain grating 2 likewise is heated until the bonding between the bitumen masses 3 and the underside of the flanges 7 is released. Thereafter the drain grating 2 is lifted to desired level, bitumen masses is refilled through the apertures 5 until the open space between the surface of the bitumen masses 3 and the underside of the flanges is filled up The drain grating 2 thereafter again is rolled until the Upper surface alignes with the surroundings and possible excess bitumen masses is removed.
• the drain and the method according to the present invention provides a possibility for simple and quick adjustment of the upper surface of drain gratings 2 to aligne with surrounding surfaces, by lifting or lowering of the drain grating, thereby achieving alignment with surrounding surfaces.
