DK 162902 B

BACKGROUND OF THE INVENTION The present invention relates to a telescopic surface water drainage well with eccentrically stored liquid cover connected to the upper end of the insertion tube of the well.

Wells for surface water of this kind have been developed to allow the well cover to be placed close to a gutter.

When depositing the position of the well, deposition errors may occur, which means that the pre-assembled well will not be positioned with the well cover close to the gutter. Although the position of the well is correctly set from the beginning, the well, 10 after it has been placed in the trench, may be displaced out of its proper position - it may e.g. will deviate from the vertical - when the pipe trench is filled again and the filling material is wrapped around the well. In this case, too, one must be able to adjust the position of the cover when it is at the final level.

For surface water wells of the type initially specified, in which the telescopic tubes consist of concrete pipes, a separate spacer or cast iron spacer, which can be rotatably mounted on the concrete insert tube, is provided with an eccentric pivot. . In this collar, the well cover is inserted with an appropriate studs therein so that it is slidable and pivotable in the collar. To adjust the position of the well cover in the lateral direction, the spacer is required to be rotated on the load-bearing concrete pipe, which necessitates the removal of surrounding filler material around the well to a substantial depth to complete uncovering of the spacer before adjustment can be made.

For plastic telescopic surface water wells, there are currently no structures which cause lateral displacement of the well cover.

The liquid cover telescopic surface water well is today the most widely used for new plants and has been designed to facilitate the adjustment of the cover height position for construction work or new coating in a simple way. The cover must be able to be level with the soil surface during the different planting stages. The various parts of the construction work must be easy to carry out. It is therefore desirable that a laterally adjustable cover should be able to be placed higher upwards as the roadway is built up 10 and then, when it is at the correct level, without circumferential digging and placement of fitting parts be brought to its proper position up the gutter. The construction previously proposed for concrete wells does not meet this requirement and, moreover, cannot be adapted to wells consisting of 15 plastic pipes.

It is an object of the present invention to provide a well cover or grate of the type specified in the preamble, which meets the above-mentioned objective, is suitable for use in wells consisting of plastic tubes, without the need for fitting parts in the form of an intermediate piece, as heretofore used in the known structures for concrete wells, and which can finally be manufactured at a low price of a few simply manufactured parts.

For the purpose of this purpose, the telescopic surface water well according to the invention is characterized by the characterizing part of claim 1.

For a further explanation of the invention, an embodiment of its object will be described below with reference to the drawing, in which: FIG. 1 is a vertical section through a telescopic surface water well with plastic tubes, according to the invention, and

3 FIG. 2 shows the one in FIG. 1, seen from above.

In the drawing, a well is shown comprising a lower pipe 10 of plastic material and an upper pipe 11 which is also of plastic material, which upper pipe is inserted into the pipe 10 as a plug-in pipe with a sealing ring 12 arranged between the pipes of and known in its own way. The insertion tube 11 is formed with a bowl-shaped extension 13, which is arranged eccentrically with respect to the other tube, and which forms a circular outward flange 14.

This flange abuts against a circular abutment 15 on a rectan-10 yellow cover ring 16, which may be made of cast iron or tough iron. On top of the flange 14 rests a lattice-shaped cover lid 17 which is conveniently locked to the cover ring 16 by means of a known device. The tube 11 can be rotated partly in relation to the tube 10 and partly in relation to the cover rim 16 15 and is additionally axially displaceable in the tube 10.

The well cover shown is a floating cover, which means that the cover can be lifted by displacing the insertion tube 11 in the tube 10 as the roadway is built up. In FIG. 1, the dashed tube 11 is shown in an intermediate position 20 where the roadway is built up to the level marked by a dashed line 18. During the displacement, the insertion tube 11 can take any turning position. In FIG. 2, the cover ring is also plotted with a dashed line in the rotational position it occupies at level 18 of FIG. First

25 When the roadway is built to its final level, where the roadway, for example. is provided with an asphalt layer 19, the insertion tube 11 can be rotated with respect to the tube 10, so that the cover rim can be positioned edge to edge with a gutter 20 disposed on the asphalt layer or in another way the gutter. Conveniently, then the flange 14 and the cover ring 16 are locked relative to each other in the final position, and this can conveniently be done by the cover lid 17 being in place and locked to the cover.

Claims (5)

The device described can also be adapted to concrete wells, in which connection the pipe 10 is constituted by a concrete pipe, while the insertion pipe 11, on the other hand, is a plastic pipe. The possibility of laterally displacing the well cover to compensate for the erroneous position of a surface water well is valuable, not only in the case of wells positioned along a gutter, but also in connection with the location of wells, e.g. in a duct or by foundations and in general where the well must be located in a particular position relative to a fixed reference point. 20 Between the circular, outward flange 14 and the circular shoulder 15, a plastic ring may be arranged.
