ßohr for sewers

The firing concerns an ear for sewage rooms, consisting of from a reinforced concrete pipe and a plastic layer resting on its inner surface and has a particularly expedient training to the object, through which the durability is significantly improved.

Sewers are made on a large scale from prefabricated concrete pipes that form a pipeline from individual HohrstücKei: joined together with a seal will. Since sewer ouer pipes predominantly are only partially filled, there is the disadvantage that if there is a lack of oxygen, the concrete shell decomposes from the inside and corrosion of the steel reinforcement

1b speed is impaired. It is therefore known that such steel-reinforced concrete pipes for sewers from inn ^ n to be provided with a plastic coating. In disadvantageously, however, this order does not result in a more solid one. Bandage, so that after a relatively short period of use

Opposite is the r.oueruu the Auf.vabe zugrc.ae, to train a Hohr for sewers in such a way that at a simple and inexpensive structure, the inner plastic layer is more durable.

The manufacture of the new pipe for sewers is done in a simple way by the fact that a prefabricated Plastic spiral pipe with steel reinforcement laid and a hydraulically setting concrete mass in the form of a shell is applied. The concrete mass is compacted and then hardens to form the concrete shell, v / elcher with the Spiral tube creates an intimate connection. The production

The position of the fire is shown in the drawing an exemplary embodiment shown in more detail. The figure shows two end-to-end face pipes for sewers, partially cut.

Depending on the pipe diameter, the wall thickness, the height and the rise height of the rib are different. The wall thickness of a spiral tube 2 is preferably about Z to I ^ mn, the height of the rib ^ - about 10 to 40 mrr. and the height of rise of the rib about 10 to 20 cm. The length of the spiral tube can be any length, but in practice it is between about 1 and z> &

Around the spiral pipe 2 around a concrete jacket 5 is attached by a prefabricated spiral pipe 2 in the usual way Way, a steel reinforcement was placed and a hydraulically setting concrete mass was applied in the form of a jacket is. This production can be done in a known manner with the help of suitable outer formwork, but the inner formwork is formed at the same time by the spiral tube. The concrete is compacted in the usual way and gives way

In the drawing it is also indicated schematically that hanging grooves 6 are provided on the front ends of the pipes 1 for sewers, which are filled with a sealing compound 9 ₅ , e.g. In addition, ring-shaped pieces of wood 7 are sandwiched between the front ends, which absorb the thermal IC expansions of the hollow pieces. An outer groove is used to accommodate a common steel ring to connect the Hohrteile. The cavities remaining between the pieces of wood 7 and the sealing compound 9 or the steel ring 3 can be filled with a suitable plastic foam compound 1. The connection of the pipes for sewers described above is only an example and can also be any ar.dsrs. It is only essential that a suitable sealing compound is used between the ends of the spiral tubes 2 made of plastic, which is not only able to absorb thermal stresses and has a sealing effect, but is also resistant to sewage and bacteria contained therein. This makes it possible, even Hohre this _A rt leave only teiigefüllt or to use them for stoisartigen wastewater.
