Plastic drainage boards are generally made of polystyrene as the raw material, and the plastic base plate is stamped into a conical protrusion, which is either a stiffening rib or a convex point (or a hollow cylindrical inorganic) structure. Plastic drainage boards are generally used for drainage in roadbed, and are mainly used in soft foundation treatment projects. In the vacuum preloading method, plastic drainage boards are generally vertically inserted into the ground to be treated, and then the excess water in the foundation is discharged by the drainage board through vacuum pumping to achieve a small post construction settlement The testing range of plastic drainage boards can be pided into rubber drainage boards and plastic drainage boards according to their materials. Plastic drainage boards can be further pided into three categories: high-density polyethylene drainage boards, polypropylene drainage boards, and polystyrene drainage boards. The products that usually need to be tested are mainly made of polyethylene, polypropylene and other resins as the main raw materials, with a concave convex surface. They are used for plastic protective drainage boards for planting roofs, underground buildings, tunnels and other engineering projects. Plastic drainage board inspection item 1: Specification and size measurement; 2. Measurement of mass per unit area; 3. Appearance measurement; 4. Physical performance measurement: tensile force at 10% elongation, maximum tensile force, elongation at break, tearing performance, compression performance, low-temperature flexibility, thermal aging performance, and longitudinal water permeability; 5. Thermal aging performance measurement: tensile retention rate at 10% elongation, maximum tensile retention rate, fracture elongation retention rate, maximum strength retention rate at 20% compression rate, ultimate compression phenomenon, and low-temperature flexibility.
