人工挖孔桩中流砂的防治方法及其应用

Prevention and Treatment of Quicksand in Manual Hole Digging Pile and Its Application

人工挖孔桩基工程中遇流砂的情况比较常见,但治理流砂时可供参考且较为系统的防治方法比较少,很多施工单位遇到流砂时便自行采用某种方法进行处理,处理未果时又采取另外一种方法,这样不仅延误了工期,还增加了费用。为避免此种情况的发生,本文较为详细地介绍了治理桩基中流砂的各种方法,并对其进行了类比,最后结合工程实例进行了论证分析,以便工程技术人员参考,从而减少工期,降低工程成本。

Its frequently happen quicksand in manual hole digging pile, but there were less prevention and treatments. Many units of construction used some ineffective methods to treatment quicksand. However, its not only dallies over the time limit for project, but also made the expense increased. In order to avoid this circs occurs, this paper particularly introduce some prevention and treatments. Meanwhile, the comparison is also analyzed. Finally, an example simulation is given in order to illustrate the effectiveness of the method in application.
