重量輕，易于運輸及操作。適應的溫度范圍廣。耐侯性優越，利用壽命極長。抗沖擊才干強，具有優良的抗化學腐蝕能力。 集水能力極強，是其他類似產品的5至10倍。  流體流動速率快，是相同直徑的鋼廣混凝土或波紋管的2到3倍。 將集水迅速排走，避免水土流失。底部為無孔部分，利于集水迅速排出，防备二次滲漏
Hard Permeable Pipe
Hard permeable pipe (plastic blind ditch, drain pipe, curved mesh water permeable pipe). There are small holes in the upper 2/3 pipe, and without holes in the lower 1/3 pipe, which can prevent the groundwater leaking twice and can quickly drained the groundwater.
1. Light weight. It is easy for transportation and construction.
2. Wide temperature range. Excellent weather resistance (anti-aging) and long service life.
3. Extremely strong impact resistance and strong resistance to chemical corrosion.
4. The water collection ability is extremely strong, which is 5 to 10 times that of other similar products.
5. The fluid flow rate is fast, which is 2 to 3 times that of concrete-filled steel tube or corrugated pipe of the same diameter.
6. There are no small holes at the bottom, and the water is quickly drained away to prevent secondary leakage and soil erosion.
Products are used in railway construction, highway construction, airport runways, golf courses, football fields, large lawns, landscaping, highways, landfill sites, slope retaining walls, tunnels and other large-scale drainage projects.
