球墨井蓋和鋼纖維蓋板的區別在于球墨鑄鐵井蓋是目前*好的井蓋，井蓋抗壓強度*高，大錘砸不爛，井蓋與底座一體化鏈接，百分之百防盜。
The difference between ductile covers and steel fiber cover is ductile iron manhole cover manhole covers are currently the best, the highest compressive strength, a sledgehammer smashing rotten, cover and the base link integration, one hundred percent security.
球墨井蓋材料采用球墨鑄鐵井圈直徑密封范圍為正負2毫米，井蓋與井圈高低配合精度為正負1毫米，配合間隙為3毫米。
Ductile iron manhole cover material using the well ring nodular cast iron seal diameter range of plus or minus 2 mm, height of the manhole cover and the well ring with an accuracy of plus or minus 1 mm, 3 mm clearance.
井蓋重量較輕，單人徒手就可以開啟。鋼纖維井蓋就是水泥井蓋，有的根本沒添加鋼纖維，但是比樹脂井蓋、高分子塑料井蓋要結實，鋼纖維蓋板比較笨重，掉角，維修開啟不方便。
The manhole cover has light weight, single hand can be opened. Steel fiber covers is cement covers, some did not add steel fiber, but the ratio of polymer resin covers, plastic cover to cover strong steel fiber is relatively heavy, off angle, maintenance is not convenient to open.
在檢查井外圈設置三個120度分布的栓固點，通過與預埋栓的鉚固，從而可以避免筑路過程中碾壓造成的井圈位移，提高了井圈的防盜性能。
Set three 120 degree distribution in the outer ring of the fixing point inspection wells, with pre buried bolt riveting, which can avoid the well ring rolling road displacement caused by the process, improve the anti-theft performance of wells ring.
