Description

The present invention relates to a pipe arrangement several pipes, into each of which a cable can be inserted, a sewer or pipe system with at least one installed Pipe arrangement with several pipes, each with a cable can be introduced, and a method for installing a Cable in a duct or pipe system.

Sewer or pipe systems, especially sewer systems or sewage pipe systems are often used for installation supply of, for example, fiber optic cable networks for telecommunications used for cation purposes. This often involves renovation work or repairs with the relocation of such Combined cable network. Overall, this way Inexpensive, especially in urban areas subsequent laying of optical cable networks realisie ren.

The cable will, for example, enter between two ducts guyed at guy points so that it is egg in the upper area a horizontally running sewage pipe runs. The cable is initiated in the shafts of the respective channel entrances kert. The cable is often also laid in an empty pipe, for example in the upper part of a horizon valley running sewer pipe runs. Such an empty pipe is in these areas on the inner wall of the channel or Pipe system attached. If an empty pipe is provided, a Cables can also be retrofitted at a later date the sewer or pipe system are pulled in.

When installing several empty pipes in a duct or Pipe system, for example in the event that one of the empty pipes  is reserved for later relocation purposes comparatively complex, since each pipe during the installation handling and installation must be handled individually.

The object of the present invention is a tube Specify the arrangement that is suitable for laying a cable is, with a laying and installation effort in one Duct or pipe system is comparatively small.

It is also an object of the present invention to provide a Ka nal or pipe system with an installed pipe arrangement, which is suitable for laying a cable, specify at which a laying and installation effort of the pipe arrangement can be kept comparatively low.

Furthermore, it is an object of the present invention to provide a ver drive to install a cable in a duct or To specify pipe system, which is a comparatively simple Ver laying and installation of a pipe arrangement and one therein arranged cable allows.

The task regarding the pipe arrangement is solved by a pipe arrangement with at least two pipes, each have a pipe wall and into each a cable can be brought, in which the tube walls by a connection are connected to each other and at which the connection web with the respective pipe wall tangential to the circumference of each because of the connected pipe wall.

The task regarding the sewer or pipe system is solved through a duct or pipe system with at least one instal gated pipe arrangement with at least two pipes, each in because a cable can be inserted and each by one Are connected to each other, in which the Pipe arrangement on an inner wall of the sewer or pipe system is fixed and the connecting web is flat on the Inner wall is applied.  

The task regarding the procedure is solved by a Procedure for installing a cable in a duct or Pipe system, in which a pipe arrangement, the at least two Has tubes connected to each other by a connecting web are connected to the connecting web on an inner wall the sewer or pipe system is attached so that the Ver binding web rests flat against the inner wall, and with the at least one cable after attaching the pipe assembly is drawn into or blown into one of the pipes.

With the pipe arrangement according to the invention it is possible to a laying and installation effort especially in one To keep duct or pipe system comparatively low, because the pipes are connected to one another via a connecting web and therefore the distance between the pipes during assembly can be kept approximately constant. With the help of Ver binding web is a compact pipe arrangement created at which the pipes cannot be handled individually. For example it is possible to initially have only one cable in one of the pipes to provide and a further cable later to a late later move into another of the pipes or blow.

By providing the asymmetrically attached connection The tube arrangement advantageously has a preferred bend direction and can be installed in one Sewer or pipe system, for example, good at branch points redirect. By the construction of the invention Pipe arrangement is created a torsionally rigid structure and thus easy alignment when mounting in favored a channel system. With the resulting front tensile bending direction due to the asymmetrical Ver binding web is at the same time a drum on small Drum diameter enables.  

When fastening the pipe arrangement to an inner wall of a sewer or pipe system, the connecting web is flat chig on the inner wall, so that a relatively simple and stable fastening of the pipe arrangement to the inner wall can follow. With such an arrangement can in particular special dirt between the pipe arrangement and the Do not deposit the inner wall of the sewer or pipe system.

In an advantageous development of the invention Pipe arrangement, the connecting web has at least one opening tion to accommodate a fastener. This is it enables the pipe arrangement or the connector with a fastening screw if necessary to attach a washer. It can be advantageous holds two or more pipes fi with a fastening screw be fixed.
