摘要
目前国内各类排水管道检测技术标准中均未涉及既有排水箱涵结构安全性评估,现有的检测技术及评估方法在应用于既有排水箱涵时存在一定的风险隐患。首先分析了现有标准体系的不足,然后从市政基础设施性能三阶段检测的角度审视既有排水箱涵检测工作的不足,提出相应对策、技术依据、方案编制、检测技术及评估方法。最后给出典型实例分析。
At present,the structural safety evaluation standards for the detection of existing drainage box culverts were not involved in the technical standards for various types of drainage pipelines in China.The existing detection techniques and assessment methods had certain potential risks when applied to existing drainage box culverts.Firstly,the limitation of the existing standard system was analyzed,and then the shortage of the existing drainage box culvert was inspected from the perspective of the three-stage inspection of municipal infrastructure performance.Finally,the corresponding solution,the technical basis,the programming,the testing techniques and the methods for evaluation were proposed and the typical case study was pr ovided.
