Three-dimensional composite drainage network-三维复合排水网

 The application of three-dimensional composite drainage network in the drainage of landfill sites; Drainage of highway subgrade and pavement; Drainage and reinforcement of railway soft soil foundation; Railway subgrade drainage, railway bottom and ballast drainage, tunnel drainage; Drainage of underground structures; Drainage behind retaining walls; Drainage of gardens and sports fields.

The characteristics of composite drainage network:

1. Strong drainage ability (equivalent to one meter thick gravel drainage).

2. High tensile strength.

3. Reduce the probability of geotextile embedding into the mesh core and maintain long-term stable drainage.

4. Long term withstand high pressure loads (capable of withstanding compression loads of approximately 3000Ka).

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

6. Convenient construction, shortened construction period, and reduced costs.
