System Description

The RIVVAL Elevated pillar-mounted trough is a system of pillar-mounted cable ducts made of glass fibre reinforced plastic (GRP), utilised without any separate mounting framework.

The system consists of the following:

i) IPE 100 steel girder, drilled and galvanised, available in:

• 1.5m
• 2.0m
• 2.5m
• 3.0m
• 3.5m

ii) mounting plate:

• Top Mounted
• Side Mounted
• Double Side Mounted

These typically include two supporting angles, one connecting plate and two mounting plates for the top mounting. The side mounting has additional T brackets(s), a backing plate (single-sided), and four connection bolts.

iii) GRP Trough profile and the lid profile, available in:

• Size 1 - 100 x 150
• Size 1A - 150 x 150
• Size 2 - 150 x 250

Note: All steel parts and mounting hardware are hot galvanised and electroplated.

The ducts are perfectly suitable for installation in topographically difficult terrain, at river crossings, on noise barriers, and on bridge railings. They are easily adapted to local conditions, e.g. at deviations around the masts of overhead lines.

Mounting plates are designed to allow for a marginal compensation for dimensional inaccuracies caused by ramming.

Note: The Type 1A installation process differs from the Type 1/2 process.

The Elevated pillar-mounted system is not for use in tunnels.

The Elevated cable duct system should only be installed outside safety zones (refuges). The minimum clearance between the cable duct system and track centreline will have to be determined by the train operating companies and its associated specifications.

Please take into account that lateral or top snow loads are to be expected if the cable duct system is installed in excavations or on slopes with snow flow, snowdrift, and the deployment of a snow plough.

In these cases, the relevant authority will have to verify and ultimately decide if utilisation of the pillar-mounted GRP cable duct system will be possible. In areas subject to falling rocks installation of the cable duct is not permissible. Please also note that the cable duct system may not be subject to any loads that result from railroad traffic.
