Canaveral sewage system

Eurohinca has carried out a Cañaveral sewage system jacking projectusing the technology DN2500 with open shield and Roadheader excavator. This intervention allowed the installation of a subway pipeline with maximum precision, guaranteeing structural safety and optimization of the sanitation system.

Location and context of the project

The project was developed in the network of Cañaveral sewer systemIn an urban environment where trenchless tunneling was essential to minimize surface disturbance. The work involved the drilling of clay and sandy soilsThis required an efficient and safe excavation system to avoid ground displacements.

Characteristics of the work

Construction method: Open shield pile driver and roadheader excavator
Pipe diameter: DN2500
Type of tunnel boring machine: Open Shield with digging arm
Geology of the terrain: Clay and sand soils
Environment: Urban infrastructure with restricted access

Technical challenges

The main challenge of the project was the excavation in soft and variable soilsThis required rigorous control to avoid collapse and guarantee the stability of the tunnel. In addition, the work had to be carried out in an area of high density of subway infrastructureThis required detailed planning to avoid interference with other services.

Another key challenge was the ground pressure management and the correct compaction of the excavated material, ensuring the integrity of the sewer without affecting the operation of the network.

Solutions implemented

To ensure the success of the project, Eurohinca implemented the following strategies:
✔️ Using the Open Shield TBM with Roadheaderideal for digging in soft and semi-consolidated soils.
✔️ Real-time geotechnical monitoring systemsThe stability of the tunnel is guaranteed at all times.
✔️ Planning and coordination with local authoritiesThe impact on the existing urban infrastructure will be minimized.
✔️ Ground reinforcement techniquesThe excavated material will be compacted to prevent slides and ensure compaction of the excavated material.

Results and benefits

The project was successfully completed, allowing the installation of the pipeline without affecting traffic or nearby urban infrastructure. Thanks to the advanced technology used, the borehole was drilled with minimal ground disturbance and high accuracy in tunnel alignment.

This project demonstrates the effectiveness of the open shield remote-controlled pile driver in complex urban environments, facilitating the modernization of sewerage networks without affecting the city's operations.
