灌注桩混凝土界面检测仪器的研发

Development of Detecting Instrument of Concrete Interface for Bored Pile

灌注桩混凝土与泥浆界面检测一直是困扰施工行业的难题,常规的手工量测误差随着空孔段的加深越来越大。利用混凝土的密度和电阻抗与其它介质不同的物性原理,研发了灌注桩混凝土界面自动检测仪,介绍了仪器的主要结构组成、软件设计、现场试验等。试验结果表明,该检测仪器能够有效解决灌注桩混凝土灌注过程中混凝土与泥浆界面检测问题,具有很好的经济、社会效益。

The detection of the interface between bored pile concrete and mud has been a bothering issue in construction,manual measurement error increases with the depth increasing of the empty hole section. Based on the physical properties that the density and electrical impedance of concrete are different with those of other media,an automatic detecting instrument of concrete interface for bored pile was developed. The paper introduces this instrument about its main structure composition,software design and the field test. The test result shows its good economic and social benefits.
