Working principle of plastic drainage plate
The plastic drainage board is inserted into the soft soil foundation with a plate inserting machine. Under the action of the upper preload, the void water in the soft soil foundation is drained from the plastic drainage board to the upper sand layer or horizontal plastic drainage pipe, and discharged from other places to accelerate Consolidation of soft foundations. In the treatment of soft soil foundation, the function design of the plastic drainage board and the construction equipment are basically the same as the bag sand well.
