By changing the cross-section of the flow from circular to rectangular, we aim to reduce weight and improve constructability and cost-effectiveness!
The "Rain Collector" is a longitudinal pipe for drainage ditches designed for permeable pavement, featuring four drainage holes and two horizontal grooves, which enhances its drainage functionality. The drainage holes are elongated, allowing for the drainage of water that has permeated into the base layer. Additionally, by changing the flow cross-section from circular to rectangular, we have achieved weight reduction, improving both constructability and cost-effectiveness. 【Features】 ■ Enhanced drainage functionality due to four drainage holes and two horizontal grooves ■ Elongated drainage holes allow for the drainage of water that has permeated into the base layer ■ Flow cross-section changed from circular to rectangular to reduce weight and improve constructability and cost-effectiveness *For more details, please refer to the PDF document or feel free to contact us.
