Drive under the road in Puertollano

Curved pile-driving project in Puertollano

In the municipality of PuertollanoEurohinca has carried out a project of curve drive for the installation of a sewage collector. The work was carried out using the DN2000 HydroshieldThe new solution allows the execution of microtunnels with high radius curves without compromising precision and structural stability.

Characteristics of the work

Excavation method: Hydroshield DN2000 remote-controlled thruster
Tunnel length: 282 meters
Radius of curvature: 600 meters
Location: Puertollano, Spain
Geotechnical conditions: Presence of clays, sands and rocks, with low water table.
Affected infrastructure: Urban crossing in industrial environment, affecting highways and proximity to sensitive areas

Project challenges

One of the main challenges of this intervention was the implementation of the curve driveThe new system, an advanced technique that makes it possible to avoid obstacles without the need for intermediate wells. For this purpose, a high-precision trajectory control system was implemented, guaranteeing the success of the route without deviations.

In addition, the work was carried out in an urban environment with critical infrastructures nearbyThis required detailed planning to avoid affecting traffic and ensure safety in the area.

Solutions implemented

To ensure the success of the project, Eurohinca implemented a series of advanced strategies and technologies:
✔️ Use of Hydroshield DN2000 tunnel boring machinewhich allows precise excavation in heterogeneous soils.
✔️ Precision guidance systemto maintain the correct alignment of the tunnel along its entire length.
✔️ Coordination with local authoritiesThe project will ensure minimal impact on traffic and industrial activities in the area.
✔️ Continuous monitoring of the excavation faceThe stability of the soil is guaranteed during the entire execution of the work.

Results and benefits

The project was completed within the established deadlinesThe installation of the collector ensured the correct installation of the collector without affecting nearby infrastructures. Thanks to the application of innovative technologies, the project will be able to minimized the impact on the surface and optimized the efficiency of the sanitation network in Puertollano.
