Product Description

Product Description
Its structure made of steel wire wrapt with PVC. It has the advantage of whole filtration and draining quickly and efficiently, high permeability, large tonnage, replacing traditional PVC pipe with wholes, eays to use, excellent function. 
Comparing with C type of the plastic drainage board, the flexible permeable hose can speed the consolidation and compression of the foundation and raise the deep reinforcing effect. 

The production process: 
Geotechnical material permeable pipe production company, spring steel wire through professional equipment to apply PVC plastic skin, after equipment to form spring coil, after the equipment tangle on polypropylene silk, after heating, can form the finished permeable pipe equipment drawing out. 

Characteristics
1. The small pore diameter, omni-directional permeable, good permeability; 
2. High compressive strength resistance, long service life. 
3. Good corrosion resistance and resistance to microbial erosion; 
4. Continuity on the whole, less joints, cohesion is convenient; 
5. Light weight, convenient construction; 
6. Soft, and soil as well as good associativit

Applications
1. All kinds of retaining wall on the back of the vertical and horizontal drainage; 
2. Highway, railway roadbed, road shoulder, soft soil drainage; 
3. Drainage tunnel, underground passage; 
4. Power ash dam and water drainage of the dam body; 
5. The central isolation belt highway drainage and protection of vegetation; 
6. Outdoor drainage of sports venues; 
7. Lateral horizontal drill empty drainage; 
8. Easy to collapse, ground drainage slope protection; 
9. The roof garden and flower terraces drainage; 
10. Slope water keep
11. Land preparation of underground water drainage; 
12. Low-lying land drainage and saline-alkali land reform system. 


Acid & Basic Resistance Test
Soft previous pipe for drainage wrapt with Polyester fibre and steel wire composite PVC outside. Its chemical composition in water and soil is following (72 hrs at room temperature. )
No apperance difference in 10% NaCI solution. 
No apperance difference in 10% NaOH solution.
