2. Excavation.
Digging of trenches according to the project specifications with stable sidewalls and safe working conditions will be done.
3. Bedding Preparation
The compacted sand or granular bedding will be prepared to support the conduit and to avoid point loads.
4. Laying Conduit Sections
The EB-35 conduits will be aligned with spacers to keep the separation uniform and to prevent shifting.
5. Jointing
Solvent cement or mechanical couplers will be used to make the joints watertight and secure.
6. Cable Pulling
Smooth bore allows for easy cable installation with very little friction.
7. Backfilling
Trenches will be backfilled in layers to ensure support and stability before concrete pouring.
8. Concrete Encasement
Encasement will share the load equally and will also keep the conduit protected from outside stress.
9. Warning Tape Installation
Warning tape will be placed over the conduit to mark it and to help avoid accidental excavation damage in the future.

PVC EB35 Conduit 315mm – Industry Insights & Best Practices
Large-diameter PVC conduits like EB35 315mm are widely used in utility infrastructure and telecom network corridors due to their strength, durability, and long service life.
PVC EB35 Conduit vs HDPE Corrugated Duct
| Feature | PVC EB35 Conduit | HDPE Corrugated Duct |
|---|---|---|
| Structural Strength | High rigidity for duct banks | Flexible structure |
| Cable Protection | Excellent for power and telecom cables | Good for telecom and drainage |
| Installation | Suitable for structured duct banks | Ideal for long flexible runs |
| Durability | Resistant to corrosion and chemicals | Resistant to soil stress |
Best Industry Practices for PVC Conduit Installations
1. Correct Duct Bank Design
Usually, big conduits like the 315 mm EB35 will be put within reinforced duct banks for major railway construction projects.
2. Maintain Properly Aligned
PVC conduits will need to be properly aligned when the cables are put through them so that there is no stress on the cables when they are installed.
3. Use Co-operating Couplings
Couplings and connectors must be made to work together according to both the manufacturer's specifications and the project's specifications.
4. Protect During Backfill
Using the proper materials to backfill will keep outside forces from damaging the conduit system.
5. Plan Multi-Utility Corridors'
Wherever there is power, telecommunications and data infrastructure, there will typically be very large conduits that provide an underground path for all three.
