市政给排水管网设计中非开挖检测修复技术

Non-excavation detection and repair technology of municipal water supply and drainage network design

当前市政给排水管网检测修复工作的修复效果一般,且存在修复耗时较长的问题。针对这些问题,本研究设计了一种非开挖检测修复技术。首先,采用视频设备对管道的状态进行初步检测,并根据数字影像完成对管道状态的结构性评估;然后,根据评估结果,对当前管道中的缺陷进行划分,确定缺陷等级构建修复方法;最后,设定管道非开挖修复步骤,完成修复操作,选择目标给排水管网,构建实验环节。实验结果证明,此方法的应用效果更佳,使用其可推动当前市政给排水管网设计施工工作。

At present,the repair effect of municipal water supply and drainage pipe network inspection and repair work is general,and the repair time is long.To solve these problems,this study designed a trenchless detection and repair technology.Firstly,the state of the pipeline is preliminarily detected by video equipment,and the structural assessment of the pipeline state is completed according to the digital image.Then,according to the evaluation results,the defects in the current pipeline are divided,and the defect level is determined to construct and repair methods.Finally,the trenchless repair steps of the pipeline are set,the repair operation is completed,the target water supply and drainage network is selected,and the experimental link is constructed.The experimental results show that the application effect of this method is better,and the use of this method can promote the design and construction of the current municipal water supply and drainage network.
