摘要
市政工程建设中,准确查明工程范围内的各类地下管线,是工程实施的必要先决条件。目前,针对地下浅埋管线、通信等有空孔的小管径深埋非开挖管线,已有一套非常完善的探测方法,但对于大管径深埋管道,尤其是曲线顶管的排水箱涵,一直缺乏有效的物探手段。本文将无人机激光雷达SLAM技术应用于深埋排水管涵的探测中,通过对实际案例的应用分析,认为无人机SLAM技术在满足飞行条件的情况下能较好适用于大管径深埋管线的探测工作,且探测精度较高,为该类管线的探测提供了新思路。
In the construction of municipal engineering,it is a necessary prerequisite for the implementation of the project to accurately identify all kinds of underground pipelines within the scope of the project.At present,there is a set of very perfect detection methods for shallow buried underground pipelines,communication and other small diameter deep buried trenchless pipelines with empty holes.However,for large diameter deep buried pipelines,especially for drainage box culverts with curved pipe jacking,there are too many limited conditions and there has been a lack of effective geophysical exploration methods.In this paper,the UAV laser radar slam technology is Applied to the detection of deep buried drainage pipe culverts.Through the analysis of the Application of the actual case,it is considered that the UAV slam technology can be fully Applicable to the detection of large diameter deep buried pipelines under the condition of meeting the flight conditions,and the detection accuracy is high,which provides a new idea for the detection of such pipelines.
