The 3D composite drainage network is made of high-density polyethylene (HDPE). The ribs are extruded through a special die. The three ribs are arranged according to a certain distance and angle to form a 3D spatial structure with drainage guide channel. The middle rib has greater rigidity, forming a rectangular drainage channel. The results show that the three-layer ribs of the drainage network have high longitudinal and transverse tensile strength and compressive strength,the drainage guide channel formed between the three-layer ribs is not easy to deform under high load, which can prevent the geotextile from embedding into the core of the geonet and ensure smooth drainage. The 3D geotechnical drainage network has high strength and high drainage type according to the requirements.

Product Description  

3D composite drainage network is a new type of drainage geotechnical materials. Made from high density polyethylene (HDPE) and processed by a special extrusion and forming process, it has a special three-layer structure. The middle bars are rigid and arranged longitudinally to form drainage channels, and the cross-arranged bars at the top and bottom form supports to prevent the geotextile from embedding in the drainage channels, maintaining a high drainage performance even under very high loads. The double-sided bonded permeable geotextile is an ideal drainage material with the comprehensive performance of "counter filtration - drainage - ventilation - protection".

Engineer Application

1.Groundwater conductive drainage layer;

2.Leakage detection layer;

3.Leachate collection and drainage layer;

4.Sealing field gas collection and drainage layer;

5.Surface water collection and drainage layer for sealing field;

Characteristics

1.Strong drainage performance (equivalent to one metre thick gravel drainage).

2. High tensile strength.

3. Reduce the chance of geotextiles embedded in the core of the network, to maintain long-term stable drainage.

4. Long-term resistance for high pressure loads (withstands compression loads of approximately 3000 Ka).

5. Corrosion resistance, acid and alkali resistance, long service life.

6. Easy to construct, shorten the construction period and save costs.

Application Case 

1.Landfill

2. Railway system drainage

3.roadbed and pavement drainage

4.Tunnel and retaining wall structural drainage
