摘要
通过对检查井周边沥青路面破碎、沉陷、井盖位移塌陷等病害形成原因进行现场实际调查,并进行原因分析,根据多年来在市政工程工作中对该问题的研究,以及在该问题治理上的一些实践经验,从检查井结构及回填工艺提出防治措施,提高城市道路质量,指导以后在新建、翻修、病害整治中施工.
This paper studies the actual investigation of the asphalt pavement damage and covers displacement around manhole, and analyzes the causes, such as cracking, sinking, cover displacement etc. According to the long-term study and practical experience in solving these problems, the paper proposes some effective prevention measures for improving manhole structures and backfilling process. It improves not only bituminous road quality, but also provides guidance for road construction,renovation and defects control.
