Section | Design Standard |
---|---|
Hydrostatic Pressure | Water pressure reinforcement 4 times standard Transformation rate in filled u with water: Less than 1% form water tank heigh |
Wind Force | Less than 60m/sec |
Earthquake Force | Stable and safe till magnitude 5.0 (Over magnitude 5.0, it needs additional reinforcement) |
Snow load | 60Kg/㎡, , Snow fall less than 30cm |
Illumination Rate | Less than 0.1% |
Out-fitForce | No leakage under condition of vertical 100Kg after install of 100A fitting with 70mm span supprot |
Water Temperature | Usable temperature: Less than 30℃, Limited temperature: Max 70℃ |
Water quality | Tap water, well water: chlorine below 50mg/ℓ Seawater: applicantion Externally Reinforced water tank(max 3m height) |
By using external reinforcement bar at the exterior, it is minimizing internal reinforcement bar. Strengthened GRP water tank system is to simplify construction and reinforce cleanliness.
