Plastic drainage board, also known as: plastic drainage board belt, plastic drainage belt, there are various shapes such as wave type, harmonica type, etc. In the middle is an extruded plastic core board, which is the skeleton and channel of the drainage belt. Its cross-section is parallel and cross shaped, and both sides are wrapped with non-woven geotextile as a filter layer. The core belt plays a supporting role and discharges the water that seeps into the filter layer upwards. It is a good vertical channel for the use of drainage consolidation method for soft foundation treatment of saturated cohesive and miscellaneous fill soil such as silt, silt, and alluvial fill, greatly reducing the consolidation time of soft soil.
