Advantages of plastic drainage board
1. Good filterability, unobstructed drainage, and guaranteed drainage effect.
2. The material has good strength and ductility, and can be adapted to the deformation ability of the foundation without affecting the drainage performance.
3. The section size of the drainage board is small, and the disturbance to the foundation is small during the construction of the drainage board.
4. Insert board construction can be carried out on super soft foundation.
5. The construction is fast and the construction period is short. Each board inserting machine can insert more than 5000m per day, and the cost is lower than that of sand wells.
