近日，德清县管仲镇沈家墩村儿童之家社工带领村里的孩子们举办了“联系党和群众，协商出路——小议员”的研讨会，让孩子们参与到村里的儿童友好改造中来。
彩虹桥社工首先带领孩子们了解“儿童友好旅行”的概念，并鼓励孩子们分享他们平时友好和危险的旅行经历。“小区井盖损坏”“过马路的时候会有交警叔叔帮忙指挥”“上次坐爸爸的电动车差点被逆行的自行车撞了”…大家对遇到的危险印象深刻，对友好的旅行经历记忆犹新。
随后，社工带领孩子们整修井盖，孩子们开始用自己构思的图案和各种颜料进行整修。五颜六色的色彩和想象力画出了栩栩如生的漫画，引得路人纷纷驻足观看，村里的井盖也焕然一新。
在管仲镇，这样的场景在各个村落社区随处可见。今年以来，为促进孩子们身心健康发展，管仲镇各村“儿童之家”各显神通，为孩子们打造了环境友好、设施齐全、服务完善的“15分钟儿童社区生活圈”。
沈家墩村彩虹桥的社工带领辖区的孩子们参与社区治理，培养他们独立思考和积极表达的能力。东八斗村的社工帮助辖区的孩子肯定自我价值，每个周末丰富多彩的手工创作活动成为学习互助的平台；北戴河村的社工引导孩子们永远感恩，带领他们为亲人和邻居做一些有意义的事情。形式多样、主题鲜明的活动极大地丰富了孩子们的课余生活。

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。
