Drainage pipe for landslide prevention! Collection efficiency = water volume × collection capacity × water flow capacity!
The "Vent Trap Collection Pipe" is a collection pipe designed for landslide countermeasures, devised to improve the efficiency of groundwater drainage work (water drainage boring). The slit width in the collection pipe is 1/10 compared to conventional pipes, making it difficult for water to escape from the inside to the outside due to its "Vent Trap Structure," which enhances and balances both collection capacity and water flow capacity, resulting in a high-efficiency collection pipe. 【Features】 ■ The opening has a 0.5mm slit to prevent the intrusion of foreign objects. ■ Collection and drainage efficiency is significantly improved. ■ Improved workability due to screw joints. * Reduces the upward movement during casing extraction. * For more details, please download the PDF or feel free to contact us.
