摘要
城市基础设施更新维护技术不断提升,对于城市生命线的地下管道的修复措施也应遵循"快速、高效、环保、经济"等多项原则,因此排水管道多采用非开挖修复技术.对于排水管道多发的汽蚀、渗漏等问题,提出一种喷涂改性环氧树脂的非开挖修复技术,相对于传统环氧树脂喷涂技术,经改性的环氧树脂可在潮湿界面固化,从而简化施工;喷涂后最快可实现 2h通水;与原管壁黏结性能良好,后期运营维护成本低;且树脂是环保型材料,施工过程中无碳排放,契合"双碳"要求.该技术可对排水管道起到非结构性、防腐抗渗的修复作用,同时可实现对异形断面和检查井的喷涂修复从而延长修复构件使用寿命,达到快速环保施工,满足城市快速更新需求.
Abstract
The renewal and maintenance technology of urban infrastructure is constantly updated and improved,and the renovation measures for the underground pipes of the urban lifeline should also follow the principles of"fast,efficient,environmentally friendly,and economical",so the drainage pipelines are mostly repaired by trenchless renovation technology.For the problems of cavitation and leakage in drainage pipelines,this paper proposes a trenchless renovation technology by spraying modified epoxy resin.Compared with traditional epoxy resin spraying technology,the modified epoxy resin can be cured at the wet interface,thus simplifying construction.After spraying,the fastest water flow can be achieved in two hours;The bonding performance with the original pipe wall is good,and the later operation and maintenance cost is low;And the resin is environmentally friendly material,no carbon emissions during the construction process,in line with the"double carbon"requirements.This technology can play a non-structural,anti-corrosion and impermeability renovation purpose for drainage pipelines,and realize the spraying renovation of special-shaped sections and inspection wells to extend the service life of repaired components,achieve rapid environmental protection construction,and meet the needs of rapid urban renewal.
