摘要
介绍一种在钻井泥浆或工业用水介质中具有自身定向和图形显示功能的超声测距仪器。它主要用于 测量桩基钻孔的井径与井筒偏斜,也可用于帷幕、沉井井筒测量以及海岸工程、岩盐水溶开采的井下溶腔测量等。 文章对该仪器的组成、工作原理和主要性能指标进行了阐述,并对仪器使用中出现的几个问题进行了讨论。
The pile foundation drill-hole measurer is a kind of ultrasonic rangefinder which can work in industrial water or drilling fluid, with the function of self-orientation and graph-displaying. Besides the diameter and inclination of pile foundation drill-hole, it can also be applied to other engineering, such as segmentation sinking,caisson sinking and halite mining by water-solution. The composition, working priciple and main specifications of the measurer are to be found in this paper, as well as several problems under some specific circumstances.
