电力电缆隧道结构病害及检测评估方法探讨
|
摘要
电力电缆隧道是目前常见的城市地下空间利用形态之一,但是该类隧道的结构病害检测技术体系和规范尚不完善,影响了该类隧道的病害评定及相应处治。电力电缆隧道的病害类型主要包括隧道渗漏水、隧道衬砌裂损、衬砌结构腐蚀这三大类型,其中影响较大的为隧道渗漏水。在电力电缆隧道的检测工作中,需要结合电力隧道的工作环境条件、功能特点,明确检测的目的和需求,有针对性地调查和收集相关的信息和资料以制定检测方案。检测的内容可以划分为外观检查、结构安全性检查、结构耐久性检查这三大类内容,以便选取适宜的仪器和方法开展电力隧道检测工作。论文提出了确定电力隧道结构区段的分项评定标准及综合技术状况评定方法,并建议依据检测评定结果对电力隧道采取对应的养护措施。
Power cables tunnel is one of the most common kinds of utilization of urban underground space,but the defect inspection and repair works for this kind of tunnel is usually limited by its uncomplete system of inspection techniques and specifications. Among the main defects of this kind of tunnel,such as the leakage problem,lining crack and damage,and corrosion of lining concrete,the most significant one is the leakage in the tunnels. The necessary information and documents of tunnels should be collected by investigation to make inspecting plans according to the working environmental conditions,function features of the tunnels and inspection purpose. The inspection works are suggested to be divvied into appearance inspection,structural safety inspection and structural durability inspection,so that the appropriate items and the relevant methods could be determined for the inspection works. The evaluation classification for the technical condition of each tunnel section could be determined according to the proposed evaluation methods,hence the appropriate maintenance measures would be adopted after inspection.
