construction materials for drains
Connecting method Introduction
PCD (Plastic cylindrical drain) has improved the shortcomings of symmetrical crease drains by creating spiral creases on the surface. It allows high flux speed regarding the weight of earth, and shows no bending effect, making it most suitable for reducing construction period in ground with high water content and for the improvement of special ground.
Shape and Type
Characteristics
- The first in Korea certified as new technology on vertical drains
- Can be used both as vertical and horizontal drain
| Type | Standard(mm) | Use | |
|---|---|---|---|
| External diameter | Internal diameter | ||
| PCD32 | 32±2 | 26±2 | Vertical drain |
| PCD50 | 50±2 | 45±2 | Vertical drain and Horizontal |
Benefit
Superior drainage efficiency
- PCD shows high water inflow and discharge efficiency to the top due to the spiral creases on the exterior surface.
- Because there is no core clogging due to soil particles, it will show excellent drainage for long periods of time.
- External asymmetrical creases allow discharge of water to the top allowing superior drainage efficiency.
