Application of Dual Axis Scanning Sonar Technology in Sewage Caisson Survey

随着城市建设的快速发展,大型污水沉井应运而生,对其进行竣工测量是必不可少的一项工作。针对传统探测方法危险系数高、测量精度低的缺陷,本文引入双轴扫描声呐技术。首先,通过对双轴扫描声呐系统的工作原理和特点进行研究,总结出一套应用于污水沉井的测量方法,对其工作模式、探测步骤以及数据处理进行了详细的阐述。最后,利用双轴扫描声呐系统对已竣工的污水沉井进行了实验分析。结果表明,双轴扫描声呐系统能够精确、高效地测量出污水沉井的尺寸,可以达到其竣工测量的精度要求,是一种有效的污水沉井测量方法。

With the rapid development of urban construction,large sewage well sinking is increasing,so it is necessary to measure the completion of the sewage well.In view of the traditional detection method,the danger coefficient is high and the measurement precision is low,this paper introduces the dualaxis scanning sonar technology.First of all,through the research of the working principle and characteristics of dual-axis scanning sonar system,summed up a set of measurement methods used in the detection of sewage caisson,work mode,steps and data processing are discussed in detail.Finally,the dualaxis scanning sonar is used to do the experimental analysis of the completed sewage well.The results show that the dual axis sonar system can accurately and efficiently measure the size of the sewage caisson,and can achieve the accuracy requirements of the completion measurement.It is an effective method for measuring the settlement of sewage.
