Plastic sewer inspection box

The innovation relates to a sewer inspection box and in particular to a sewer inspection box that consists of consists of a cast body made of several prefabricated, interconnected, parts assembled from plastic.

Such sewer boxes, in particular sewer inspection boxes known design, however, do not have a satisfactory flow profile, which is why they are discharged larger amounts of water cannot meet the requirements »

It is the task of the ~ innovation, a card index in particular to provide a sewer inspection box which always has a correct flow profile so that the above disadvantages are avoided becomej and which is characterized by the fact that its lower end Is hemispherical, connected to the manifold Connecting pipes open into this hemispherical part. With these measures there is always an appropriate drainage guaranteed.

According to a very useful embodiment is located
the lowest point of the hemispherical part on the central axis of the connecting pipes. On the one hand is such a thing
Sewer inspection box practically easier to manufacture than before, while on the other hand the flow profile is still improved »;

In order to simplify the arrangement of the channel box has
this according to: a preferred embodiment, one at a time
upper lying near its upper and lower ends
and / or lower flange. If such a flange
or the flange set is missing, the sewer box can possibly be pressed upwards by the groundwater pressure and consequently the connections with the plastic supply pipes can be damaged.

According to a further embodiment of the innovation is a Channel box 'with; rather * made of concrete or other material' - pressure catch plate, which avoids direct pressure on the trunking box. In this version If the sewer box remains in its place, they can Connection lines not damaged even in the event of a subsidence will. When the ground is set, one needs the position of the channel box not to change and it is sufficient to explain the reason under to fill the pressure absorbing plate.

To produce a trunking box from several preformed parts that form a rigid or non-detachable unit the individual parts made of plastic are nested and by spraying on, ■ in particular reinforced polyester resin layers, connected.

The innovation is based on an exemplary embodiment Drawing 'explained in more detail, with further measures according to the innovation being discussed.

Fig. 1 shows in longitudinal section a duct box in the form of a

Sewer inspection box and
FIG. 2 shows a side view of the box according to FIG.

In the figures, a sewer inspection box 1 is shown, which is made of one, made of several plastic, such as hard polyvinyl chloride, polyester resin, epoxy resin, etc., prefabricated,

connected parts 3 to each other preferably non-detachably assembled hollow body bestehti "For this purpose, the different parts of polyvinyl chloride and / ocfer" polyester resin are assembled. The lower end of the channel box 1, namely the bottom part H-_ of reinforced polyester resin is formed hemispherically, the terminal connections 5, which are connected to the collecting line 6, open into this hemispherical part 4 and on its lower side. The lowest point 10 of the hemispherical bottom part 4- is advantageously on the central axis of the connecting lines 5. This gives a better flow profile while at the same time the production Technically simpler and more evenly. Furthermore, the standard requirements can be met more easily. This also always ensures a perfect water drainage. This prevents a sewer box 1 assembled in this way from upward pressure from the groundwater is pressed j the box is provided in the vicinity of the upper or lower end with an upper or a lower flange 7 and / or. In order to simplify the arrangement and prevent damage to the connecting lines 5 in the event of a lowering, the duct box is equipped with a Drui: purchase catch plate ^; 9 provided. When the bottom settles, there is no need to change the position of the sewer box and it is sufficient to pour the earth under the pressure absorbing plate.
