Installation Precautions
l Silicon Duct /Micro duct(DI) shall be constructed on a good foundation and must be manually reinforced in unstable soil.
l The Angle between the center of the curved pipe should be as small as possible to reduce the lateral pressure when laying the cable.
l Silicon Duct /Micro duct(DI) Minimum bending radius of duct laid, shall not be less than 1m.
l The interface section of Silicon Duct /Micro duct(DI) shall be straight and free of burrs and shall be connected with matching sealing couplings.
l The outside of the connector should be waterproof.
l Special plugs should be used to seal both ends of the Silicon duct(DI) and prevent mud and water from entering the plastic duct during duct installation.
l Silicon Duct /Micro duct(DI) should be used appropriately, and small duct or cable should not take up large outer protective duct, thereby reducing duct utilization.
l Commonly used Silicon Duct is 40mm to 50mm in diameter and has good railing proof performance so that no special railing can be used.
l The protective measures of air blowing pipe ditches and the setting of marker stones shall be carried out according to the relevant standards issued by the Ministry.
FIG1- Soil cross section
The depth of the Silicon Duct /Micro duct(DI) should be determined in the following table according to factors such as soil and environmental conditions.
No. | Paved lot and soil quality | Buried depth (m) |
1 | Common soil, hard soil | ≥1.0 |
2 | Semi-stony (gritty soil, wind fossils, etc.) | ≥0.8 |
3 | All stone, fluid sand | ≥0.6 |
4 | Suburbs, towns and villages | ≥1.0 |
5 | Urban streets | ≥0.8 |
6 | Crossing railway (from subgrade surface), highway (from pavement base) | ≥1.0 |
7 | Middle divider and shoulder of high - grade highway | ≥0.8 |
8 | A ditch, canal, pond | ≥1.0 |
9 | The river | Same as the requirements for underwater cable burial depth |
