Overhead line

Maps the course between supporting structures, to which the conductor cables are subsequently assigned. As a rule, the course corresponds to that of the ground wire.

Example

Description

Utility trench

The earthwork (excavation) for laying the pipeline(s) is referred to as pipeline trenching (open trench method). Analogy to the excavation pit but for pipelines. It does not matter how the lines are laid. Not used with trenchless methods (e.g. ploughing in).

Description

Culvert / media duct / route section through buildings

Utility corridor, line channel, utility corridor, galleries, collectors, collective ducts

The culvert is an under-crossing line and is often found in connection with watercourse crossings or dams. Culverts can contain one or more lines. In the field of drainage, the culvert is usually equated with the sewer.

The media channel is an underground structure used by several media for supply and disposal. A media channel is usually accessible.

Route section through buildings: These are not internal lines, but supply and disposal lines of a public nature that are laid in buildings and are accessible.

Example

Description

Route section

Tube bundle, tube block

The route section is a homogeneous area which is constant from beginning to end. Also referred to as a tube bundle or tube block.

Example

Description

Protective tube

Protective cable tube, pipe section

The primary purpose of the protective tubes is to protect against external influences (mechanical and moisture). At the same time, empty tubes can also create capacity for later expansion (without new earthworks).

In addition to protective tubes, there are other profiles (historical) and construction methods.

The protective tube itself can also be installed in a protective tube (often in the field of electricity and telco).

Description

Bridge / pipe bridge

Bridges are used to cross obstacles (railways, roads, rivers, etc.) and are collected as structural elements.
