Stabirails new method for slab track construction guarantees faster construction times and a lower cost for laying ballastless railroad tracks.
Stabirail’s new method for milling concrete blocks so the rails can be assembled directly on the concrete bed is tried and tested and is being carried out by a slab track laying train consisting of:
- Concrete Milling Machine with filter press (waste water recycling)
- Diamond Drilling train
- Anchoring train
- Tanker (10,000 litres water and 2500 litres diesel)
- Lorry with water tank.
Stabirail has designed and developed a unique method for milling concrete blocks so that the rails can be assembled accurately and directly on the concrete, thus guaranteeing faster construction times and a lower cost for laying ballastless railroad tracks.
Our slab track laying train consists of 3 machines that are being used consecutively. First the Concrete Milling Machine passes through.
This new technology to mill concrete rail beds is designed to work with millimeter accuracy. It’s a continuous process in which the entire concrete blocks are milled simultaneously. The entire machine is operated by a 3D system and is capable of working on parabolic transitional curves and transitional slopes.
The diamond discs are water cooled to prevent dust formation. The cooling water is provided by a 10,000-litre capacity tanker. After the sludge is separated, the cooling water is reused. This machine can operate completely autonomously.
Following the concrete milling machine, comes the Drilling Train. The middle part of our slab track laying train makes diamond core drilled holes in the concrete bed. These holes will afterwards be used to anchor the track. It operates fully autonomously because it is equipped with a generator and water tanks.
As the drilling is carried out with a water-cooled diamond drill, vibrations passed to the surroundings are kept to a minimum and there is no dust formation.
The final part of our slab track laying train, the Anchoring Train, consisting of two parts. First is the anchoring unit, the second one, the driving unit.
The driving unit includes a generator, water tank, air compressor and a hydraulic crane, so this machine can also operate autonomously.
