摘　　要：随着国内逆作法施工的普及,在施工过程中保证一桩一柱钢管立柱桩的垂直度尤为重要。采用在立柱上预埋测斜管的方法,实现了实时对立柱垂直度的测试。施工完成后通过预埋声测管方式,采用声波透射法检测钢管柱内填混凝土与立柱下节桩部分,结合钻孔取芯检测内填混凝土质量,有效地保证了立柱桩施工效果。With the popularity of reverse construction in China,it is particularly important to ensure the perpendicularity of one-pile and one-column vertical-column pile in the construction process.The method of embedding an inclinometer pipe on the column is adopted to realize the real-time test of the vertical degree of the column.After the construction is completed,the embedded acoustic test tube is used to detect the inner concrete of the steel pipe column and the pile under the column by the acoustic transmission method,and the quality of the inner concrete is tested by drilling the core,which effectively ensures the construction quality of the column pile.
