White Plastic Drainage Board
Drainage Strip (named Plastic vertical drain) is like a cross parallel strips made of polyethylene and polypropylene as core board and wrapped by non-Woven Geotextile as filter layer. Drainage Sheet Strip is to play a supportive role and drain the leaking water and air out of ground. Geotextile Composite Drainage Strip is inserted into soft soil foundation by drilling machine, under the upper part of the prepressure loading. The pore water in soft soil will be drained out through plastic vertical drain to the horizontal drainage system, and drain outward to accelerate the soft ground consolidation.
Drainage Sheet Strip Feature
1. Good Filtration performance, smooth drainage, drainage effect is guaranteed.
2. Good strength and ductility, can be suitable foundation deformation capacity without affecting drainage performance.
3. The section size of drain is small, so disturbance is small too to the foundation when in operation.
4. Fast construction and working time is short. Each drilling machine can finish over 15,000 meters, which greatly save cost and shorten the construction period.
5. Flexible construction and low requirement to construction environment, applicable to variety of soft soil foundation and super soft soil foundation reinforcement treatment.
PVD is applied to reduce construction time and speed up the consolidation of soft ground for the following work:
| · Bank revetment |
| · Development of seaport area |
| · Road, railway & airport construction |
| · Improvement of dredged clay fill |
| · Construction of gas & oil storage facilities |
| · Development of building & industrial complex site |
