Description

after pulling the flexible power line that feeds the head. The intensity of the water jets and the head travel speed can be controlled by varying the water pressure in the structure and the pressure can be adjusted to about 100 bar.

The flexible pipeline of the structure has a diameter of only about 1 or 25 mm; the removable head is only approx. 5 to 6 cm in diameter, with different opening sizes to be used depending on the diameter of the pipe to be cleaned. With such a structure - such as WOMA delivers - significantly longer sections can be cleaned than previously constructed sections of 20-60 m. The invention is based in part on this realization and partly on the fact that it is not necessary to clean a manhole, but to place cleaning eyes with properly formed drain pipes instead.

Accordingly, it is an object of the present invention to provide a sewer system which eliminates a large portion of the cleaning shafts, can replace some of them and replace the remainder with cleaning eyes provided with descending downpipes, thereby achieving significant savings in construction.

It is a further object of the present invention to introduce the installation work instead of the construction work in relation to the placement of the channels 25 and the individual pieces and pieces, which is made possible by the assembly of the channel into plastic mirrors and pieces. This can happen eg. with known rubber gasket fasteners, with the additional benefit of

-13:. '·. . not only is the joining work simplified and shortened in time, but also the waterproofing of the canal is improved, which excludes the possibility of contamination of the environment, and the plastic pipes, due to their flexibility, allow some movement of the earth.

Accordingly, the essence of the sewer system according to the invention is that it has cleaning grains consisting of 10 downpipes and a mouthpiece connecting it to the channel, omitting part of the cleaning shafts hitherto used and replacing another part.

In accordance with the present invention, the sections between the reserved drainage manholes of the sewer system are preferably constructed of plastic pipes and plastic moldings; and use rubber sealed coupling fittings to connect each piece.

In this way, most of the cleaning shafts can be left out, which is very important both in terms of cost and construction time; The assembly of the plastic duct from the finished fittings also facilitates construction, and the smoothness, better cleaning and reliable waterproofing of the pipe wall all add to the benefits.

The invention will be explained in more detail below with reference to the accompanying drawings.

Figure 1 is a plan view of a detail of an exemplary sewerage network with a previously used dense shaft installation; Fig. 4 is a side view similar to Fig. 3, in which the mouthpiece is connected to a channel with a diameter larger than its outlet pipe; Figure 6 illustrates the connection of its side outlet from the housing to the sewer in an underground side view in connection with a cleaning eye. depicts the connection of the side channel out of the housings to the channel, also in relation to a cleaning eye, in an underground side view.

As shown in Fig. 1, the duct 1 is currently interrupted by breakage points, at the junction points of the building ducts 2, and furthermore, by cleaning at a maximum distance of 20m according to the regulations.

Figure 2 shows a single cleaning shaft 3 in the same channel section at the strongest breaking point in the sewer system of the present invention, whereas only the cleaning eyes 4 are required at the connection of the building channels 2 and at a much larger distance of about 60-100 m.

Fig. 3 shows an underground view of a cleaning eye 4 located in the channel 1. For example, uniformly

A 0200 mm descent pipe 5 is connected to the mouthpiece 6, which is connected to the channel 1 by a bidirectional curved portion. The connection is a known rubber seal. The upper end of the downpipe 5 ends in a small concrete head 7 covered by a cover 8. Bidirectional curved guidance allows the machine cleaner to do its cleaning work in both directions. Because the aunt of Channel 1 falls; the upstream leg of the mouthpiece 6 is not quite vertical: however, this can be corrected for its connection with the vertical landing tube 5.

Fig. 4 shows a cleaning eye similar to Fig. 3, except that the upwardly extending stem of the mouthpiece 6 having a 200 mm diameter has a larger channel 1, e.g. Connected to a 400 mm diameter pipe, it also ends in a 400 mm bidirectional pipe fitting.

Figure 5 shows the connection of a building trunk to the channel 1 in an underground view. Here, the downpipe 5 between the elbow 10 and the mouthpiece 11 of the channel 1 is further interrupted by the mouthpiece 9 which connects the building channel 2 to the downpipe 5.

Fig. 6 shows a cleaning eye in which the building 5 is connected to the landing pipe 5 in a manner similar to that of Fig. 5, but coming from two sides at two different levels.

The presented examples show that a variety of level alignments and connections can be solved in a simple way by using various prefabricated plastic pipe sections and simple assembly work. The machine cleaning tool can pass well through the pieces with the correct curvature: in our experience, this curvature does not have to be greater than a radius of 30-50 cm.
