Bargas - Mocejón AVE Railway Junction

Construction of subway crossing under the railway line

The project of the Bargas - Mocejón AVE railway crossing consisted of the construction of a subway tunnel for the passage of pipelines using the technique of pipe jacking. For this purpose, a Hidroshield DN1500 shielddesigned to cross different types of soil without affecting the railroad's operability.

General project details

LocationDate of birth: Bargas - Mocejón, Spain
Main objectiveConstruction of a pipeline underpass under the railroad line.
Geological conditionsMixed soil with presence of clay and sand.
Technology usedHydroshield DN1500.
Total tunnel length: 65 meters.

Technical specifications

Nominal diameter: 1,500 mm.
Method usedDrilling with Hidroshield shield and pipe jacking.
Reinforced structuresConstruction of retaining walls to guarantee the stability of the land.

Logistics and technical challenges

The project was developed in an area with active railway activity, which required careful planning to avoid disruptions and ensure the safety of the infrastructure.

Project highlights

Controlled excavation under the railway lineminimizing settlements and vibrations.
Continuous monitoring of drilling progressensuring the stability of the tunnel.
Use of Hidroshield technology to pass through the ground without affecting the operation of the railroad.

Environmental and social impact

The construction of the AVE Bargas - Mocejón railway crossing has improved the transport infrastructure without affecting the surface.

Reduction of environmental impactthanks to trenchless excavation.
Modern and efficient infrastructureoptimizing rail connectivity.
Guaranteed safetywith constant monitoring and stability control in the excavation.
