Which is a good plastic drainage board

Description :

　　Plastic drainage boards, also known as plastic drainage belts, come in various shapes such as wave shaped and harmonica shaped. 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 filter layers. The core belt plays a supporting role and discharges the water seeping in from the filter layer upwards. It is a good vertical channel for soft foundation treatment of saturated and viscous soils such as silt, silty soil, and backfill soil using drainage consolidation method, greatly reducing the consolidation time of soft soil.

　　1. Packaging appearance: Adopting a circular pancake shape with a center roll, 200 meters per roll, with a diameter of about 0.8M~1.3M and a height of 0.1M.

　　2. Cross section: The core board is parallel cross shaped to form a harmonica shape.

　　Working Principle:

　　The plastic drainage board is inserted into the soft soil foundation using an insertion machine. Under the action of the upper preloading load, the void water in the soft soil foundation is discharged from the plastic drainage board to the sand layer or horizontal plastic drainage pipe laid on the upper part, and then discharged from other places to accelerate the consolidation of the soft soil foundation. In the treatment of soft soil foundation, the design and construction equipment of plastic drainage boards are basically the same as those of bag sand wells.
