- 3 description

The invention relates to a sewer manhole consisting of prefabricated parts with a base part with a prefabricated one Flume, one of this axially protruding shaft tube and with radially arranged Connection elements for sewer pipes.

From DE-PS 26 05 535 a sewer manhole is already known in which the with a prefabricated The bottom part provided with the channel is open at the top and over which the connecting pipe socket is inserted radially provided manhole pipe is put over to after gluing and sealing the two parts together to form the sewer shaft. With this sewer system it is However, the disadvantage is that not only different base parts for different connection configurations must be prefabricated and kept ready, but also appropriately adapted manhole pipes with connecting pipe sockets inserted and fastened in the appropriate places. While the shaft pipe usually made of asbestos cement, the bottom part is made of concrete. To when the water table is high To achieve adequate buoyancy protection, must in the known system with the Floor part a special reinforced concrete floor slab can be anchored.

The invention is based on the object of a sewer shaft also consisting of prefabricated parts to create, in which only the prefabricated base part the various connection configurations must be adapted for the sewer pipes, while commercially available pipes without connecting pieces as a manhole pipe corresponding length can be used.

The sewer shaft according to the invention is thereby characterized in that the connecting elements are integrated flush in the bottom part and that on the bowl-shaped bottom part an axial annular flange with a Opening is provided into which the shaft pipe is inserted.

Such a sewer has the advantage that when transporting the prefabricated items to the Construction site and when assembling no damage due to protruding connection pieces on the shaft pipe can arise, as is the case with the known sewer system. Because of that mostly made of asbestos cement manhole pipe no connection pieces have to be used, fall up on the eventual cutting to the desired length - no further, environmentally harmful processing steps. By inserting the shaft pipe in the annular flange of the cup-shaped bottom part, it is advantageously possible to encapsulate and seal of the two parts from the outside.

According to an advantageous embodiment of the invention the sole and the ring flange of the bottom part are made of concrete as integrated buoyancy protection.

A simple, inexpensive connection of the sewer pipes to the sewer shaft according to the invention to enable, according to a further embodiment of the invention, the connection elements as in the base part cast-in joint pieces made of elastic material. About the sealing effect and adhesion To improve these joint pieces compared to the bottom part, it is expedient to use the outer surface

of the joint pieces formed with a surface-enlarging and a form-locking toothing.

The invention is explained below using an exemplary embodiment explained in more detail. Show it:

Figure 1 is a section in the vertical direction through the sewer shaft according to the invention along the section line A-A of Fig. 2,

FIG. 2 shows a section through the sewer shaft according to FIG. 1 along the section line B-B and

FIG. 3 shows a detail from FIG. 1 in an enlarged illustration.

The base part 1 shown in the figures, prefabricated from concrete, has a bowl-shaped structure and consists from a sole 8 with a prefabricated channel ^ and an adjoining one extending axially to the shaft Annular flange 3. In the opening 10 of the annular flange 3, the vertical shaft pipe 2 is inserted and sealed by a sealing compound 5.

As connection elements for the sewer pipes (not shown) joint pieces 4, which are used in the Manufacture of the bottom part 1 are poured in. To improve the adhesion of the gel pieces 4 and For better sealing, the outer surface of the joint pieces is provided with a surface-enlarging and a form-locking toothing 6 equipped-

For assembly at the construction site, the bottom part 1 with the desired connection configuration with the Sole 8 placed on the level, solidified soil layer. Due to the heavy weight of the bottom part 1 No additional buoyancy protection is required, even when the groundwater level is high. Afterward the sewer pipes are inserted into the openings without the use of additional, loose sealing rings 7 of the joint pieces 4 inserted. Then the manhole pipe is cut to the required length 2 inserted into the opening 10 of the axial annular flange and the gap between them Sealing compound 5 sealed.

Because the joint pieces 4 are integrated flush in the base part 1, there is a risk of damage greatly reduced during transport and when installing the sewer manhole according to the invention. Due to the joint pieces 4 made of elastic material, there is sufficient mobility the connection with the sewer pipes is guaranteed, so that there are no Can result in damage.
