球墨井盖和钢纤维盖板的区别在于球墨铸铁井盖是目前*好的井盖，井盖抗压强度*高，大锤砸不烂，井盖与底座一体化链接，百分之百防盗。
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.
球墨井盖材料采用球墨铸铁井圈直径密封范围为正负2毫米，井盖与井圈高低配合精度为正负1毫米，配合间隙为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.
井盖重量较轻，单人徒手就可以开启。钢纤维井盖就是水泥井盖，有的根本没添加钢纤维，但是比树脂井盖、高分子塑料井盖要结实，钢纤维盖板比较笨重，掉角，维修开启不方便。
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.
在检查井外圈设置三个120度分布的栓固点，通过与预埋栓的铆固，从而可以避免筑路过程中碾压造成的井圈位移，提高了井圈的防盗性能。
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.
