摘要
检查井沉陷及井周路面破坏是道路检查井的主要病害类型,尤以机动车道和交叉口处多发且病害也最为严重。它严重影响道路使用寿命和交通安全。近年来,道路检查井病害问题也日益引起了社会和相关政府部门的关注。北京、天津、济南、哈尔滨等多地针对该问题进行了专项维修整治,措施多样,效果不一。针对道路检查井病害产生的原因,结合实际工作,详细阐述了应用现浇钢纤维速凝混凝土处治道路检查井病害的优势、主要技术要点等,从而为检查井路面病害处治提供技术解决方案。
The subsidence of manhole and the pavement damage around manhole are the main types of road manhole diseases,especially more common and the most serious at the motorways and intersections,which seriously affect the service life and traffic safety of road.In recent years,the problems of road manhole disease have increasingly attracted the attention of the society and relevant government departments.The special maintenance and rectification to solve this problem are carried out in Beijing,Tianjin,Jinan,Harbin and other areas with various measures and different effects.Aiming at the causes of road manhole diseases,combined with the practical work,the advantages and the main technical essentials in the application of the cast-in-situ steel fiber quick-setting concrete to treat the diseases of road manhole are expounded in detail so as to provide the technical solutions for the treatment of manhole pavement diseases.
