The Composite Wave Drain Pad can quickly drain excess water in the wading project, reduce the pore water pressure, and improve the overall stability of the project. Compared with the traditional graded gravel or yellow sand drainage layer, it has the following advantages:
1. Using geocomposite drainage pads to replace traditional drainage pad materials can save 15% to 30% of the cost, which does not include the benefits of the convenience of construction.
2. The use of geocomposite drainage pads is simple and quick to construct, which greatly simplifies the complicated grading process of traditional gravel drainage pads, effectively reduces the construction period and saves cost.
3. After calculation, the drainage capacity of a 5mm-thick geocomposite drainage pad is equivalent to that of a 50cm-thick gravel drainage layer under the same conditions, and it is not easy to be blocked, which can greatly reduce the volume of the drainage layer.
