多级高边坡削坡质量检测技术研究与应用

Research and application of high-side slope surface repairquality automatic detection technology

针对高陡边坡削坡整平施工中,坡面人工检测困难、测量数据不全面等问题,提出一种机载式削坡质量自动检测方法。首先以北斗定位点为基准建立挖机斗齿尖坐标运动轨迹方程,并进行斗齿磨损误差修正;然后分析挖掘机斗齿尖空间坐标轨迹与坡面特征之间的关系,通过对斗齿尖坐标数据识别、采集算法研究,实现了利用斗齿坐标间接表达坡面质量的目的。工程应用实践证明该方法满足坡面削坡质量检测精度要求,取代了人工测量,提高了施工效率。

Regarding the problems of difficult manual detection of slope and incomplete measurement data in the construction of high and steep slope sparing,an automatic detection method of airborne slope cutting quality is proposed.Firstly,the equation of the motion trajectory of the excavator tooth tip coordinates is established based on the Beidou positioning point,and the wear error of the excavator is corrected.Then the relationship between the spatial coordinate trajectory of the excavator s tooth tip and the slope characteristics is analyzed.Through the study of the recognition and acquisition algorithm of bucket tooth tip coordinate data,the purpose of indirectly expressing the slope quality by using the tooth coordinate is realized.The practice of engineering application proves that this method meets the requirements of slope cutting quality inspection accuracy,replaces manual measurement,and improves construction efficiency.
