Installation Guide
- Site Assessment & Trench Design: Route, depth, and spacing will be planned according to the project requirements.
- Excavation: Create a smooth trench base by removing debris, rocks, and obstacles.
- Bedding Preparation: The duct will be protected by sand or fine soil.
- Laying Duct Sections: Sections will be aligned correctly and slope will be maintained.
- Jointing: Secure joints will be achieved by connecting with solvent weld or mechanical couplers.
- Concrete Encasement: The concrete will be poured around the duct as per EB-35 specifications.
- Cable Pulling: The smooth interior of the duct will make the installation easy and damage-free.
- Backfilling & Warning Tape: The backfill will be laid in layers to protect the duct and indicate its location for future excavation.
