The upper two-thirds of the rigid permeable pipe has small holes, while the lower one-third is solid without holes, which can prevent secondary leakage of groundwater and quickly drain it. The product is used in railway construction, highway construction, airport runways, golf courses, football fields, large lawns, landscaping, expressways, landfills, slope protection and retaining walls, tunnels, and other large-scale underground drainage projects.It is lightweight, easy to transport and operate. It has a wide temperature tolerance range, good weather resistance (anti-aging), and a long service life. It has strong impact resistance and excellent chemical corrosion resistance. Its water collection capacity is strong, 5 to 10 times that of similar products. The fluid flow rate is fast, 2 to 3 times that of steel-reinforced concrete or corrugated pipes of the same diameter. It quickly drains collected water to prevent soil erosion. The solid bottom section facilitates rapid water drainage and prevents secondary leakage.
