30多名社区儿童最近来到修罗新村的生态家园林立晖。呼朋唤友,四人一组,组成几个创作团队,有条不紊的驻扎在各个创作场所,挥舞画笔。花、熊猫、圣甲虫、羊羔、鸭子等。栩栩如生,充满童趣。大家纷纷和自己小组的作品合影,用笑声为社区带来一道新的风景。
第二章
建造一个昆虫旅馆-
近日,孩子们聚集在生态家园邻里惠二楼的多功能厅,大家分成四组,搭建了一个“昆虫宿舍”。活动中使用的diy材料主要是木板、锯末、小圆木、松果、瓦楞纸等可回收材料。昆虫旅舍的框架是用木板拼起来的,用螺丝拧紧,里面填充了松球、锯末、小圆木、瓦楞纸等材料。这是昆虫生活的地方。

昆虫旅馆由木头、稻草、砖块、塑料软管等回收材料制成,为各种昆虫提供了不同类型的小空间。任何花园都可以放置不同大小的昆虫旅馆,提高花园的生物多样性。

孩子们发挥想象力,为自己的“昆虫旅社”穿上漂亮的“外衣”。
接下来,老师给孩子们科普了一点昆虫旅社的知识。松果可以吸引瓢虫,可以控制蚜虫和介壳虫。树枝、树干、树皮等。能吸引吃粘虫等的布钉。钻孔的原木会吸引传粉昆虫,如壁蜂、切叶蜂和其他独特的蜜蜂。

搭建昆虫旅社的活动,不仅让孩子们发挥了创意,放飞了梦想,还收获了科学知识,寓教于乐,热情高涨。
第三章
–创意绘画–
孩子们聚集在一起,以胶水为颜料,以石头为材料,发挥他们的想象力和创造力进行绘画。

看啊!他们用不同颜色的奶油胶涂在背景上,用小石头和人、动物等组件摆出图案。奶油胶水干了之后,一个五彩缤纷、璀璨夺目的新世界展现在我们面前!
创意绘画帮助孩子插上想象的翅膀,捕捉心灵的音符,探索生命的吉祥羽毛,让心灵更加宽广。

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。
