Prefabricated Drain Wick Drain

200m/piece, Diameter0.8-1.3m, Thickness 0.1m, the core boards are made of mixture from PPand PE.
1. When a structure or embankment is constructed on a site that is underlain by soft wet soils, the load on the soft soil is initially partially supported by the incompressible water in the soil pores. Over time, the excess pore water pressure dissipates as the water slowly drains out from under the load. As this occurs, the load is transferred to the soil, the soil consolidates and settlement occurs. This process could take years to occur and result in damage to the structure.
One solution is to compress the soil prior to construction by placing a temporary fill load on the site. The time required for this preload to achieve the required compression can be shortened by installing wick drains/prefabricated vertical drains. The drains shorten the pore water drainage path thereby permitting the consolidation to occur in weeks instead of years.
2. The applications of wick drains are as diverse as the imagination of the design engineer. Typical applications have included dams, large storage areas, highway embankments, tanks, bridge abutments, buildings, and airport runways.
3. The SPB-A/B/C/D prefabricated vertical drains is the new material of reinforcement of ultra-soft ground and soft soil. Reinforcement of soft soil of it's mechanism, design, construction equipment is the same with sand wick.
4. Our factory is specialized in producing Prefabricated Vertical Drains. Our products are identified in quality by the national testing agencies for professional research. Various technical indicators have reached the design requirements, products are strictly in accordance with the process and industry standards JTJ/T257-96 in producing and self-test to ensure high quality products.
