QXY-5型存储式钻孔倾斜仪的研制与应用

滑坡深部位移变形监测是滑坡稳定性监测的一种重要手段,是滑坡整体位移变形动态综合监测的重要组成部分。目前国内外在实现滑坡深部位移监测方面主要采用钻孔倾斜方法解决。文章针对目前国内外深部位移监测设计孔的监测情况及手段,指出了目前测量仪器及测量方法的不足,提出并研制了一种全新的无缆存储式钻孔倾斜仪—QXY-5型存储式钻孔倾斜仪,介绍了其研制及使用情况。该仪器测量方式为数据自动存储,不使用电缆和地面仪表克服了随着孔深的增加电缆长度也随之增加带来的工作强度及天气对地面仪表的影响;设计了数据自动存储功能,避免了人工记录所带来的误差影响,提高了测量的效率和准确率;深孔测量配合准确计数的手动绞车对孔深无限制,测量操作非常方便。

The development and application of QXY-5 memery borehole inclinometer

The deep displacement and deformation monitoring of landslides is an important means in landslide stability monioring.It is also an important part of dynamic integration monitoring of overall displacement deformation of the landslide.Now deep displacement monitoring of landslides is mad by using borehole inclinometer at home and abroad.In this paper,aiming at the condition and means of deep displacement monitoring at home and abroad,the deficiency of the current measuring instruments and methods are indicated,and a new memory borehole inclinometer-QXY-5 is provided and developed.The measurement data is memorized automatically,without use cable and ground instrument.So the problem is overcame,which the cable length increases with the borehole deep increasing to bring work intension and the effect of weather on ground instrument.Data automatic memory is designed to avoid the error caused by human,this improves efficiency and accuracy. Hole deep is not limited by using hand winch and accuracy count.It is very convenient to operate.
