Abstract

A lining material for the repair or replacement of pre-existing sub-surface pipes further incorporates a data transmission that is a light wave guide e.g. fibre optic cable.

Description

The The invention relates to an inliner for the rehabilitation of laid pipelines according to the preamble of claim 1.

Processes for the rehabilitation of laid pipelines belong to the known state of the art and are in particular in the German industrial standard DIN EN 13566 "Plastics piping systems for the renovation of buried non-pressurized drainage networks (free-flowing pipelines)" These procedures subsequently introduce tubing, the so-called in-liners, into existing pipelines, thereby creating an internal pipeline within the pipeline to be renovated, without rebuilding the pipe must be laid.

to Providing high-performance broadband connections for data transmission for industry and private households data lines are needed. These are mostly in the Area formed by wide area networks in the form of optical fibers. Within urban buildings that are made up of traffic engineering or structural reasons digging trenches designed to lay such lines disadvantageous and uneconomical, Be used for laying such data cables existing conduits or sewage networks used. In the currently known methods the laying of such lines is done by this by dowels or special clamping devices on the inside the pipes are attached. Another possibility This is the data line between an inliner and the pipe inner wall to lay, with the inliner the data line to the pipe inner wall pushes and stabilizes.

at such laying works it is necessary, either extensive Installation work to be carried out within the pipeline, wherein sometimes extensive and expensive technical means used have to come and the wall above all older piping for the insertion of dowels or the inclusion the clamping devices is often not suitable. Or it has to the cross sections of the inliners are dimensioned so that between the Outer wall and the inner wall of the pipe enough Space for laying the data line remains. This is happening difficult for pipelines that change over their course and often unforeseen cross-sectional changes exhibit. The inliner and the data cable can be used during the Insertion entangle, causing complications during installation comes from inliner and data line.

It consists of the aforementioned problems underlying the invention The underlying task is to specify an inliner for the rehabilitation of laid pipelines. which easily combines the installation of data cables can be.

The Invention is provided with an inliner having the features of the claim 1 solved. The dependent claims contain appropriate or advantageous embodiments of the invention Contraption.

Of the Inliner according to the invention is characterized by a in the wall of the inliner integrated data transmission conductor out. Separate laying of inliners and cables for data transmission is therefore no longer necessary, the inliner takes over even a data-transferring function in addition to the conventionally planned tasks in the field of pipeline rehabilitation.

In an expedient embodiment is the Data transmission conductor an optical waveguide. such Leaders set a standard for a modern broadband Data transmission.

Of the Optical waveguide is in an appropriate training a fiber optic cable integrated into the wall of the inliner is. In the area of branches is expediently a data transmission coupling device, in particular an optical fiber coupling, provided. The inliner itself is through a pipe or pipe stranding, a hose, a winding tube or a single pipe lining insertable into an existing pipeline. As a result, existing pipelines can be uncomplicated as components retrofitted to a network for data transmission and be used.

Of the Inliner according to the invention will be described below an embodiment explained in more detail become. It will be for the same or equivalent parts the same reference numerals are used. It shows:

1 a cross section through an exemplary inliner,

2 a longitudinal section through an inliner with an exemplary coupling device.

1 shows an exemplary inliner 1 in a cross-sectional view. The inliner consists in its base material of a flexible tubular fabric, in particular of a plastic fiber fabric such. As polyester, or a glass fiber fabric, or from a comparable flexible material, such as rubber or plastic. In the case of a fiber fabric, the fabric material may be impregnated with a synthetic resin which hardens under pressure, heat, UV radiation or the like further environmental influences and reliably closes defects of the pipe to be rehabilitated.

In the wall 1a of the inliner are several data transmission conductors 2 distributed, which are optical fibers, preferably optical fiber cable with its own insulation. These consist of a bundle of optical fibers. Of course, electrical conductors, electrically conductive fibers or electric cables may be provided with a corresponding insulation.

in principle can any number of data transmission over be distributed in the wall of the inliner. The number and the arrangement the wall-mounted data transfer ladder depends on the thickness of the wall of the liner or the required Cross section of the data transmission ladder.

2 shows the in 1 shown arrangement in a fragmentary longitudinal section in conjunction with the representation of a coupling device 4 in which branches of at least one of the data transmission conductors provided in the liner wall are provided. At the in 2 The coupling device shown is essentially a splice connection 5 in which from the fiber bundle of a data transmission conductor, in particular therefore from the fiber bundle of the optical waveguide or the optical fiber cable, some of the light guide from the wall of the inliner as an outgoing cable harness 6 led out and are connected to outgoing, not shown here further light guides. Corresponding coupling devices can also be realized for electrically conductive data transmission conductors.

The Pulling the inliner into the existing pipeline to be rehabilitated carried out with a suitable relining method, in particular a pipe or Rohrstranglining, a hose. Spiral tube or single tube lining. The existing pipeline is simultaneously renovated and laid used by the data transfer manager. In the range of branches Especially fiber-optic cables are becoming fiber-optic coupling systems realized on the inliner. House connections are thereby by the Inversation of the light guide created.

Further Embodiments emerge from the subclaims or by expert modification of the embodiments shown.
