与传统的窄边井盖相比，出现了井盖下沉、周边路面碎裂、车辆碾压噪音等一系列缺点。新型宽檐井盖有效解决了这一市政道路管理的老大难问题。城市道路全天连续使用，路面上的窨井设施也会受到车流量、道路使用年限增加等因素的影响，出现各种病害。
井盖有方形和圆形，形状各异。而且这些井盖大多是传统的窄边井盖，很难与周围道路压实。车辆碾压时，荷载压力会直接传递到井身，容易造成井盖下沉，周围路面破损，给市民出行带来不便。在进行维修时，也会陷入频繁维修、频繁损坏、频繁修理的循环维修困境。另外，车辆碾压这些井盖时会发出叮当声，产生噪音。为了减少窨井设施的沉降和窨井周围的损坏，提高道路交通的舒适性，采用了一种新型的宽边窨井盖来代替原来的窄边窨井盖。新型宽边井盖不仅可以将原来的方形井盖改造成圆形井盖，还可以将荷载压力转移到路面结构层，避免直接压在井身上，大大降低下沉的可能性。而且井盖是用沥青碾压的，保证与路面的平整和密实。如果新井盖下沉，只需撬松抬高，在法兰面底部填沥青压实即可，大大提高了维修速度。新井盖的开合部分设计了橡胶垫圈，这样车辆过去碾压时就不会发出很大的声音。

井盖的类型有哪些？
井盖类型非常的多，像是上水井盖、污水井盖、雨水井盖、雨水箅子、电力井盖、路灯井盖、通信井盖、电信井盖、热力井盖、燃气井盖、电缆井盖、化粪池井盖等等。不同的井盖有不同的功能，上水井盖是供水用的井盖，下水井盖则主要是用来排除掉路面上的积水的。像湖南甄金井盖的类型，有不锈钢井盖、铸铁井盖、复合树脂井盖等类型，铸铁井盖中，球墨铸铁圆井和铸铁沟盖板使用的较多。因为路面上的车辆多，而球墨铸铁井盖的承压能力比较好，公路上使用的多的就是这类型井盖了，而且井盖的类型也多。
There are many types of well covers, such as water supply well covers, sewage well covers, rainwater well covers, rainwater grates, power well covers, street lamp well covers, communication well covers, telecommunications well covers, thermal well covers, gas well covers, cable well covers, septic tank well covers, and so on. Different manhole covers have different functions. The upper manhole cover is used for water supply, while the lower manhole cover is mainly used to remove water from the road surface. There are various types of manhole covers such as stainless steel manhole covers, cast iron manhole covers, and composite resin manhole covers. Among the cast iron manhole covers, ductile iron round wells and cast iron trench covers are more commonly used. “Because there are many vehicles on the road, and the pressure bearing capacity of ductile iron manhole covers is relatively good, this type of manhole cover is commonly used on highways, and there are many types of manhole covers.”
什么球墨铸铁井盖
球墨铸铁井盖是球墨铸铁产品的一种，球墨铸铁通过球化和孕育处理得到球状石墨，有效地提高了铸铁的机械性能，特别是提高了塑性和韧性，从而得到比碳钢还高的强度。球墨铸铁是20世纪五十年代发展起来的一种高强度铸铁材料，其综合性能接近于钢，正是基于其优异的性能，已成功地用于铸造一些受力复杂，强度、韧性、耐磨性要求较高的零件。球墨铸铁已迅速发展为仅次于灰铸铁的、应用十分广泛的铸铁材料。所谓“以铁代钢”，主要指球墨铸铁。
Ductile iron manhole covers are a type of ductile iron products. Spheroidal graphite is obtained from ductile iron through spheroidization and inoculation, effectively improving the mechanical properties of cast iron, especially its plasticity and toughness, resulting in higher strength than carbon steel. Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is similar to that of steel. It is precisely based on its excellent performance that it has been successfully used to cast some parts with complex stress and high requirements for strength, toughness, and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material, second only to gray iron. The so-called “replacing steel with iron” mainly refers to ductile iron.
什么是不锈钢井盖？
什么是高分子井盖？
“高分子井盖是采用不饱和聚脂树脂为基体的纤维增强热固性复合材料,用压制成型技术制成,是一种新型的环保型井盖。”
绿色环保：不生锈、绿色环保、节约不可再生资源。
防盗功能强：高分子井盖系复合材料具有不可再生性，不能回收利用，因而具有主动免被盗功能。
平衡能力好、承压力强：盖座咬合精度高，配合性好提高了道路的通行能力和行车舒适度。
日常维护简便、费用低：重量轻、防盗窃、寿命长、易识别，便于日常的开启和维护，有效降低了养护的劳动强度和更新费用的支出。
