The invention relates to a rainwater well or a similar sewage or sewer well comprising a jacket consisting of a unitary pipe or a plurality of overlapping parts, which jacket is provided with a bottom and at least one outlet connection.

The rainwater membranes currently used and available, or sewage or sewer wells, respectively, are usually made of either metal or plastic by casting (with the exception, of course, of traditional concrete membranes). Such wells are generally solid cylindrical or tubular bodies closed at the bottom at the bottom. The connections of the discharge connection to such rainwater wells and the like are usually made at the factory, as a result of which the customer has to determine the directions, heights and diameter of the discharge connection when ordering the wells. In particular, however, the split kite is unnecessarily a limiting factor when determining the final location of the rainwater membrane. The diameter of the discharge joint usually determines the type of pipe to be used with the rainwater membrane. As a result, rainwater films have previously had to be manufactured separately for each pipe size, so that large series of production have not been achieved in order to reduce the cost of production. If, on the other hand, it has been desired to use the same type of film in connection with different pipe sizes, it has been necessary to use separate expansion or contraction pieces between the discharge connection and the pipes, which has made installation work more difficult and increased costs.

The object of the present invention is to provide a new type of rainwater membrane which does not have the disadvantages described above. To accomplish this, the invention is characterized in that each outlet connection comprises nested outlet pipes, the inner pipe of which communicates with the interior of the rainwater membrane and the outer pipe terminating in the rainwater-membrane jacket wall so that the substantially annular space between the inner pipe and the outer pipe is excavated. closed.

The most important advantages of the invention are that in connection with the same rainwater membrane 2 76160 1 two different pipe sizes can be used without a sludge member. In addition, shrinkage and expansion pieces are obtained by using a very wide range of pipe sizes. As a result of the above, the production batches are made larger and the manufacturing costs are lower as a result.

The invention will now be described by way of example with reference to the accompanying drawing.

Figure 1 shows a perspective view of a rainwater well to which the solution according to the invention has been applied.

Figure 2 shows in more detail a vertical sectional view of a rainwater well using the solution according to the invention.

Thus, Fig. 1 shows an axonometric view of an embodiment of a rainwater membrane 1 to which the solution according to the invention has been applied. The rainwater well according to Fig. 1 consists of detachable parts, the top of which is a collar part 10, on top of which a manhole cover (not shown in the figure) is to be installed. The collar part 10 is connected by a detachable connection to a sleeve-shaped vertical pipe 8, the length of which can be freely chosen. An extension 2 is also connected to the lower end of the vertical pipe 8 by a detachable connection 17, which is provided with an outlet connection 12 comprising nested outlet pipes. The connection 17 is such as to allow the extension 2 to be attached to the vertical pipe 8 in any position 25 with respect to the common vertical central axis of the vertical pipe 8 and the extension 2. The direction of the riser connection 12 can thus be chosen freely. A similar connection 17, with which the vertical pipe 8 and the extension 2 are connected to each other, has a second extension 4 connected to the lower end of the extension 2, which is provided with two outlet connections 12 as shown. The number of outlet connections 12 in the extension 4 can be other than two, their number may be, for example, three or four or more.

Due to the nature of the joint 17, the extension part 4 can be fitted to the extension part 2 so that the direction of the towing joints 12 is desired. According to Fig. 1 35, a bottom part 6 is further connected to the lower end of the extension part 4 by a similar connection 17, which is also provided with an outlet connection 12. The base part 6 can also have a desired number of risers 12, the directions 3 The base part 6 can also be adapted to the desired position with respect to the vertical axis, whereby the directions of the towing connections 12 therein are made suitable. Since the connections 17 between the standpipe 8, the extensions 2 and 4 and the base part 6 are similar to each other, it is self-evident that the desired number of extensions 2 or 4 can be mounted together.

Fig. 2 shows a vertical section of a rainwater well 1 corresponding to Fig. 1, so that the structure of the riser connections 12 according to the invention is shown in more detail.

According to Figure 2, the outlet connections formed in the walls of the extension parts 2 and the base part 6 comprise two nested outlet pipes 20 and 22. Preferably, the outlet pipes 20 and 22 are arranged nested concentrically. From the outlet pipe, only the inner pipe 22 leads into the well. The outer pipe 1 (3 20) terminates in the membrane wall. Water can then only escape from the well through the inner pipe 22. Such an arrangement allows sewer pipes of two different sizes to be installed in the rainwater membrane 1. The sewer pipes are thus fitted over either the inner pipe 22 or the outer pipe 20 and Due to the arrangement 22, the base 14 of the base part 6 20 could not be formed just below the bottom edge of the walls of the base part 6, but the base 14 is raised some distance above the bottom edge so that the walls continue below the base 14. This base must be at substantially the same height as the lower edge of the outlet pipe 22 so that water flows more easily away from the bottom part 6.

The solution according to the invention has been described above in connection with a rainwater well, which consists of several interconnected parts. However, it is clear that the invention can also be applied to a rainwater membrane consisting of a uniform tubular valve closed at its lower end. As can be seen from the above, the structure and mutual arrangement of the outlet pipes are essential to the invention and not so much the structure of the rainwater membrane itself.

The invention has been described above only with reference to the preferred embodiments shown in the figures. However, it is in no way intended to limit the invention to these examples only, but many modifications are possible within the scope of the inventive idea of '76160 1' as defined in the following claims.
