摘要
针对温州永嘉世界贸易中心工程钻孔桩的废弃泥浆,通过添加相同的化学药剂结合真空预压采用不同的排水方法进行了模型桶试验,从排水速率、排水总量和含水率等方面对比研究。试验发现:改进排水方法后,废弃泥浆含水率在短时间内(80 h内)从处理前的180%~190%,降低到处理后的60%~80%。研究表明,药剂真空预压改进排水方法后处理废弃泥浆的效果十分显著。
The model barrel experiments were carried out on different drainage methods for the waste mud of bored pile in an engineering project in Wenzhou with the same chemical agent combined with vacuum preloading, the comparison analysis was made on drainage rate, total amount of drainage and water content. The experiments found that with the improved drainage methods, the water content of waste mud is reduced from original 180% - 190% to 60% - 80% in a short time （within 80h） , which shows remarkable effect of waste mud disposal by improved drainage methods of additive agent combined with vacuum preloading.
