摘　　要：市政道路工程中,传统各类检查井在车辆荷载及雨水冲击下往往会出现井圈下沉、路面开裂、井盖隆起等现象,严重影响行车的舒适度及安全性。并且传统井圈维修中需要用混凝土浇筑固定井圈,工期长。采用"可调试五防(防盗、防沉降、防响、防移位、防滑)卡簧式球墨铸铁井盖"其优点在于作业面小,施工完毕后可即时通车,既确保施工质量又能使车辆白天通行无阻。瓯海大道、汤家桥南路、府西路等工程应用效果较好,在类似工程中具有一定的推广价值。In the municipal road projects, various traditional manholes have the phenomena of manhole crib sinking, pavement cracking and manhole cover upheaval under the vehicle load and rainwater impact,which serious influence the comfort and safety of driving. The maintenance of the traditional manhole crib needs the concrete to pour and fix the manhole crib with a long construction period. The "adjustable fiver-preventive(burglary, settlement, noise, displacement and skid) snap-spring nodular cast iron manhole covers is adopted. Its advantages are the small working face and open traffic in time after construction not only ensuring the construction quality, but also keeping the vehicles open traffic all day. The engineering application effects of Ouhai Avenue, South Tangjiaqiao Road, Fuxi Road and other projects are better, and have a certain promotional value for the similar projects.
