Telescopic rainwater well

The present invention relates to a telescopic rainwater well provided with an eccentrically flat, floating cover connected to the upper end of the well inlet pipe.

Rainwater wells of this type have been developed to allow the well cover to be placed right next to the curb. When determining the position of the well, setting errors may occur, as a result of which, in the case of a pre-installed well, the well guard is not aligned with the curb. Although the location of the well is correctly determined from the beginning, the well, after being placed in the pipe grave, can move from its original position - for example, it can deviate from the vertical - when the pipe grate is refilled and the filler material is sealed around the well. It must also be possible to adjust the position of the cover when it is in the final plane.

In connection with rainwater wells of the type described at the beginning, in which the telescopic tubes consist of concrete tubes, a special cast iron or cast iron spacer is arranged for lateral adjustment of the well cover, which is rotatably mounted on a concrete si-25 weathering tube and is eccentrically fitted. This collar has a well cover inserted with a suitable cam so that it can be moved and rotated in the collar. To laterally adjust the position of the well cover, it is required that the spacer 30 be rotated by a load-bearing concrete pipe, making it necessary to remove the surrounding filler material around the well to a substantial depth to completely release the spacer before adjustment is possible.

35 For plastic telescopic rainwater wells, there is currently no structure that allows the manhole cover to be moved laterally.

A telescopic rainwater well with a floating cover is currently the most widely used in new construction work and has greatly facilitated the adjustment of the height position of the cover in connection with construction work or a new pavement in a simple manner. The guard must be able to be located at ground level during the various stages of construction. The various stages of construction work must be easy to carry out. It is therefore hoped # that the laterally adjustable guard should be able to be raised continuously as the road surface is constructed and, once level, it should be able to fit in its correct position with the curb without digging around the ground and without fitting adapters. The device previously proposed for concrete wells does not meet this hope-15 black and, moreover, cannot be used in connection with wells consisting of plastic pipes.

The object of the invention is to provide a well cover of the quality indicated in the introduction, which fulfills the above wish, is well suited for use in wells formed of plastic pipes, which lacks adapter pieces in the form of a spacer used in connection with a known structure for concrete wells. finally, it can be made at a low price from a few 25 parts made in a simple way.

To achieve this date, the telescopic rainwater well according to the invention has acquired the features of claim 1.

To further explain the invention, an embodiment thereof 30 will now be described with reference to the accompanying drawings, in which Figure 1 is a vertical sectional view of a rainwater well comprising plastic pipes according to the invention and Figure 2 is a plan view of the rainwater well shown in Figure 1.

The drawings show a well comprising a lower tube 10 of plastic material and also an upper tube 11 of plastic material inserted into the tube 10 as an insertion tube, the sealing ring 12 being arranged between the tubes in a manner known per se. The insertion tube 11 has a shaped cup-shaped extension 13 arranged eccentrically with respect to the rest of the tube and forming a circular outwardly directed flange 14. This flange rests against a circular shoulder 15 of a rectangular cover ring 16, which ring may be made of cast iron or sitkoraudasta. On the flange 14 rests a lattice-like protective cover 17, which is preferably fixed to the protective ring 16 by some known device. The tube 11 is rotatable on the one hand with respect to the tube 10 and on the other hand with respect to the cover ring 16 and in addition it is axially displaceable in the tube 10.

The well cover shown is a floating cover, which means that the cover can be raised by moving the inlet pipe 11 in the pipe 10 as the road surface 20 is built. In Fig. 1, the insertion tube 11 is shown in dotted lines in its intermediate position, in which the road surface is constructed to the level indicated by the dotted line 18. In connection with the transfer, the insertion tube 11 can be given an arbitrary rotational position. Fig. 2 also shows the cover ring in dotted lines in the rotational position in the plane 18 of Fig. 1.

Once the road surface is constructed to its final level, where the road surface is provided with, for example, an asphalt layer 19, the insertion pipe 11 can be rotated relative to the pipe 10 30 to cause the guard ring to align with the edging 20 or other edging. The flange 14 and the cover ring 16 are preferably fixed relative to each other in their final position and this can advantageously take place in such a way that the protective cover 17, when in place of the 7777 2 and attached to the cover ring 16, holds the flange 14 against the shoulder 15.

The cup extension 13 may be made as a separate part and may be suitably attached to the rest of the insertion tube 11. In order to allow the well cover to suit different road surface slopes, a ball joint bearing for each cup extension can be fitted to the connection between the cup extension 13 and the other insertion tube 11. to allow a deflection to occur with respect to the rest of the insertion tube 11.

The described device can also be used in connection with concrete wells, in which case the pipe 10 consists of a concrete pipe, while the insertion pipe 11 is a plastic pipe.

15 The possibility of moving the manhole cover sideways to compensate for the incorrect location of a rainwater well is valuable not only for wells located in connection with curbs, but also for wells such as streets or foundations and generally where the well should be located in a fixed location. with respect to the lupine.

A plastic ring 25 may be arranged between the circular outwardly directed flange 14 and the circular shoulder 15.
