Excavations are the foundation of modern infrastructure, whether installing fiber optic networks, power lines or charging stations. But what exactly happens underground before you have superfast Internet or a functional charging station? In this blog, we take you through the process of excavation, the challenges involved and how innovative techniques ensure efficiency and minimal inconvenience.
1. Preparation and site survey
Before the first shovel goes into the ground, a site survey is conducted. This includes:
- Mapping the existing infrastructure such as gas, water and power lines.
- Assessing soil conditions to determine the most appropriate excavation technique.
- Applying for necessary permits from local authorities.
2. Markings and safety measures
To prevent damage to existing cables and pipes, excavation locations are marked. This is often done with colored paint or bollards. In addition, safety measures such as:
- Closing the work area to protect pedestrians and traffic.
- Employing specialized excavators and tools to increase precision.
3. The digging itself
Depending on the project and soil type, different excavation techniques can be used, such as:
- Traditional digging: With excavators and manual work.
- Steered drilling: For minimal nuisance in urban areas.
- Suction technology: In which soil is removed with suction equipment to prevent damage.
During the excavation process, the trench is carefully dug, then cables or pipes are placed and properly insulated and protected.
4. Backfilling and site restoration
Once the network infrastructure is in place, the trench is backfilled. This is done with the original soil or a new type of fill for added stability. Paving and landscaping are then restored so that the surrounding area is affected as little as possible.
5. Testing phase and conclusion
After construction, all connections are tested to ensure optimal operation. Only when everything is functioning correctly is the project considered complete and the new infrastructure can be put into service.
Environmental and safety measures during excavations
In excavation work, it is very important to ensure both the environment and the safety of workers. Therefore, strict environmental and safety measures are taken:
Environmentally friendly practices
- Sustainable reuse of soil: Wherever possible, excavated earth is reused rather than disposed of.
- Minimum CO₂ emissions.: Using electric or hybrid excavators reduces the carbon footprint.
- Protection of flora and fauna: When working in natural areas, measures are taken not to disturb trees, plants and animals.
Safety measures for workers and local residents
- Workers wear protective clothing, helmets and reflective vests.
- Work areas will be clearly cordoned off to protect pedestrians and traffic.
- Special protocols ensure quick and appropriate action in case of emergencies.
Through a combination of careful planning, modern technology and strict safety regulations, A-NET ensures that excavations are performed as efficiently and safely as possible.
