检查井非开挖整体修复方法探究

Research on the overall repair method of non-dig of manhole

检查井面临的环境十分恶劣,极易被引发各种缺陷,因此寻求快速有效的修复方法十分重要。非开挖修复技术以简便快捷、非开挖等优点为检查井修复领域开辟一个新的途径。该文主要针对非开挖整体修复的四种工艺展开研究,包括紫外光固化法、玻璃纤维整体贴片加固法、检查井预制内衬法和离心喷涂法等。在工程实践中对传统修复工艺进行了改进,并将修复2 年后效果进行了分析和评价。

Facing harsh environment, the manhole can be easily caused various defects. Therefore, it is very important to find a quick and effective repair method. The non-dig repair technology opens up a new way for the field of manhole repair because of its simple and fast, non-dig etc. four kinds processes of non-dig for overall repair were studied in this paper, including UV curing method, glass fiber integral patch reinforcement method, inspection well prefabricated lining method and centrifugal spraying method. And the traditional repair process was improved in the engineering practice, and the effect of repair 2 years later was analyzed and evaluated.
