Research on material performance indexes for plastic blind drains

An introduction is given to the raw materials, forms, and engineering characteristics of the plastic blind drain-a new type of geosynthetic, and it is pointed out that the porosity of opened voids, porosity, discharge capacity, and compressive strength of materials can be taken as the performance indexes of the plastic blind drain. In this paper, test methods for the porosity of opened voids, discharge capacity and compressive strength are emphasized, and their experimental results are given. The research shows that the plastic blind drain is of good performance in water collecting, drainage, compressive strength, and endurance.
