原本不起眼的井盖遇上Yuwa的奇思妙想,会擦出怎样的火花?
为丰富校园文化,增进亲子关系,加强家校联系,积极营造优美的校园环境氛围,促进学生心理健康成长,宇泰小学于5月举办了“小润通”亲子井盖涂鸦大赛。
经过评选,在提交的数百件参赛作品中,58名学生的设计脱颖而出,被学校邀请绘制校园亲子井盖。
5月20日这个特殊的日子,孩子们在父母的陪伴下走进校园。活动开始,欧蓉校长为获奖的孩子们颁奖。大队雷坤老师进行了简单的讲解培训,每组家庭都领到了自己的工号。根据宇泰井盖藏宝图,他们先找到了自己需要画的井盖,和父母一起画了起来。
大家充分利用井盖的造型和特点,以“爱、鹿、校园”为主题,将原本“满是灰尘”的井盖改造成了一件艺术品。
看,校园里的井盖都披上了独特的外衣,让不起眼的井盖成为我们校园里一道亮丽的风景线,让每一个孩子都能在学校找到“小幸运”,获得积极的情感体验。
活动结束后,参与活动的家长对活动给予了高度评价。其中,2105班的父亲李云灿说,“感谢学校组织这次活动,很有意义,很享受。我们平时工作忙,陪孩子的时间有限。这种活动增加了我们父母和孩子之间的互动。如果学校组织类似的活动,我们会积极参加。”
宇泰小学将继续团结家长和社区的共同努力,促进学生的心理健康,以德育,智慧,体力,美容和劳动。

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。
