Manises Airport cross collector

Construction of subway crossing at the Manises Airport

The project of the Manises airport junction consisted of the execution of a subway tunnel for the installation of a sewage collector under the airport runway. It used a Hidroshield DN2500 shielddesigned to pass through soils composed of clay and gravel with precise settlement control.

Manises airport cross collector

General project details

  • LocationManises Airport, Spain

  • Main objectiveInstallation of a subway collector without affecting airport operations.

  • Geological conditionsClay and gravel.

  • Technology usedHydroshield DN2500.

  • Total tunnel length: 230 meters.

  • Maximum recorded settlement: 3 mm.

Technical specifications

  • Nominal diameter: 2,500 mm.

  • Method usedExcavation with Hidroshield shield.

  • Continuous monitoring of settlements to avoid affecting the airport's runway.

Logistics and technical challenges

The project required precise control of excavation progress due to the proximity of the runway and ongoing airport operations.

Project highlights

  • Controlled excavation under airport runwayminimizing settlements.

  • Continuous monitoring by means of topographic measurementsThe stability of the runway is guaranteed.

  • Use of Hidroshield technology to pass through low cohesion soils without surface disturbance.

Environmental and social impact

The construction of the collector at the Manises Airport made it possible to improve the sewage infrastructure without interrupting air traffic.

  • Reduction of environmental impactby using trenchless excavation methods.

  • Modern and efficient infrastructureensuring the airport's operability.

  • Guaranteed safetythanks to precise excavation and constant monitoring.
