ADLER Technologies is an expert in engineering, turnkey solution and equipment in the concrete building material industry. The company developed a unique process and innovative technology, known as the automated concreting train.
Based on the company’s exceptional mastering of concrete, with both the material and processing, it remains an unmatched solution for continuous concrete production in difficult work areas and hard environmental conditions.
The trains provided by ADLER Technologies are used for continuous concrete production, utilising an industrial process of only three operators. These multipurpose trains are adapted for the concreting of tunnel tracks, platforms, pylon foundations for electrical projects, outside tracks and all projects near the tracks.
This fully automated solution includes a concrete train (the key to the solution), which is a mobile concrete plant that guarantees a continuous process for long-term production at industrial scale, a concrete shuttle that makes the link between the train and the dispenser unit, a concrete dispenser unit and a storage plant. ADLER Technologies make it adaptable, clean, safe and efficient, while meeting the most complex quality specifications.
Adaptable concreting trains
Each concreting train is made of a pumping wagon, a mixing plant wagon, storing wagons (for aggregates, cement and water), power and waste wagons. The train capacity is based on production shifts and the number of storing wagons can be adjusted easily according to daily production.
Concrete is produced timely and continuously and, depending on a constant conformity control with concrete specifications, concrete formulation and production can be adjusted easily and automatically if required. Adjustment can also be made at any time during the process in order to take into account the climatic conditions of the tunnel. Concrete production can be immediately withheld, without producing train waste in case of unexpected contingencies.
Efficienct continuous concrete production
The concreting process is fully automated and monitored. On board, the laboratory follows and records the information concerning the quality of the concrete for every metre of the track produced, as well as ensuring the most efficient traceability. This continuous quality check guarantees consistent concrete quality.
Safe and clean concreting process
All conveyors and train equipment are equipped with fences and mobile protection to ensure the highest level of safety. The dispenser unit reduces the number of workers on the rack, who are positioned and assigned specific work places during the process.
All elements are designed to avoid any waste on the existing tracks, as well as collect all waste generated during production as the concrete train is equipped with specific containers.
Proven experience with Gotthard tunnel, Channel tunnel and Thames river tunnel
ADLER Technologies ensures credibility, accountability and integration in complex management projects, which in the past have included the St. Gotthard tunnel, Channel tunnel and Thames river tunnel.
For the St. Gotthard tunnel, ADLER Technologies provided an unmatched technological solution, meeting premium quality, operation safety, and specific precision requirements for the construction project of the century. The whole concreting train, 500m long and 23 wagons weighing over 1,200t, was delivered by the company for cementing the 57km railway tunnel (114km of track) at a rate of 260m per day.
With the Channel Tunnel, the basic weight of the train, which is made up of 19 wagons, is approximately 1,500t with an overall length of 540m. The unit carries materials to mix 275m³ of concrete in less than 4hr. Engineered for the Channel tunnel, this train was the biggest mixing plant on rails in Europe in the 90s and is used to concrete tracks for the high-speed TGVs (Train de Grande Vitesse) trains in France.
The Thames river tunnel in London was commissioned in 2004, this train was the solution for concreting tracks in the railway tunnel that passes under the river Thames. This unique concrete train consisted of 19 wagons, which included all mandatory equipment for construction in addition to two welfare and workshop wagons.
