Abstract:The plastic vertical drain is a vertical channel of water discharge in foundation treatment by vacuum preloading. The effect of the performance on the foundation treatment is very important. A series of physical and mechanical tests are carried out for different plastic vertical drains. The transverse sectional area of the integral core plate is slightly larger than that of the separation core plate. The mechanical properties of the anti-clogging core plate is superior to those of the conventional core board. For the membrane samples, the thickness of woven cloth is thinner than that of the non-woven fabric, with lighter quality. The mechanical performance is also significantly inferior to that of the non-woven fabric. For the non-woven fabric samples, the thickness of the anti-clogging non-woven fabric is thinner than that of the conventional one, with lighter quality. The mechanical performance is superior to that of the conventional non-woven fabric. The anti-clogging integral drains show optimal performance.
