渠堤渗漏检测技术及多源融合新技术初探

Review of Canal Leakage Detection Technology and Preliminary Study on New Multi-Source Fusion Technology

平原河流河堤与输水渠道的填方段渠堤普遍存在渗漏破坏隐患,渗漏初期不易察觉,一旦形成渗漏通道则难以修复。因此利用精确、高效的渠堤渗漏检测技术对渠堤进行检测,对保障渠道安全意义重大。对此,分类评介钻探取样法、人工探视法与地球物理探测法等传统堤防渗漏检测技术的特点、测试原理、技术适用性,阐述集成人工智能的检测载体新技术--水下机器人的技术优势与特点,在此基础上提出“天-地-水”一体化填方渠道渗漏检测系统新技术设想。论述通过无人机红外成像巡检、热力-水动力耦合溯源、水下声纳机器人声纳成图、探地雷达扫描、5G移动通信技术、检测数据实时传输等多源检测技术,综合实现科学、无损、高效的渠堤渗漏检测,从而为渠道渗漏智能化检测提供新思路。

There is a common problem of seepage damage in the embankment of the fill channel of plain rivers and water conveyance channels,which is difficult to be detected at the initial stage of seepage damage and difficult to repair once the seepage channel is formed.Therefore,scientific,accurate and efficient detection technology of canal embankment leakage is of great significance to ensure the safe operation of the channel.In this paper,the technical characteristics,testing principles,technical advantages and disadvantages,and the applicability of traditional dike leakage detection technologies,such as drilling sampling method,manual visitation method and geophysical exploration method,are classified and reviewed.This paper also introduces the technical advantages and characteristics of underwater vehicle,a new detection carrier technology integrating artificial intelligence.On this basis,a new technical assumption of the integrated sky-land-water fill channel leakage detection system is put forward.The multi-source fusion technologies,such as infrared thermal imaging inspection of unmanned aerial vehicle,thermal-hydrodynamic coupling traceability,sonar mapping of underwater sonar robot,ground penetrating radar scanning,5G mobile communication technology,and real-time transmission of detection data,are proposed to realize scientific,accurate,nondestructive and efficient detection of canal embankment leakage,which may provide a new idea for intelligent detection of canal leakage.
