在环保成为全球关注的今天,黑色路面道路又称绿色环保道路,以其防粉尘、无污染、降噪、美观等优越性深受广大城市建设者和市民的喜爱。然而,随着道路“黑化”改造的不断进行,城市道路中检查井常出现下陷或安装不平整的现象,从而影响整条道路的外观,更影响了行车的舒适性。由于沥青砼路面施工工艺的不同,使得井框安装标高的掌握成为安装工作中的重点与难点。 Today, as environmental protection becomes a global concern, black pavement roads, also known as green roads, are loved by many city builders and citizens for their advantages of dust prevention, no pollution, noise reduction and beautiful appearance. However, with the continuous transformation of road “blackening”, inspection wells in urban roads often experience subsidence or uneven installation, which affects the appearance of the entire road and affects the driving comfort. Due to the different construction technology of asphalt concrete pavement, the mastery of the well frame installation elevation becomes the key and difficult point in the installation work.
