我国“抗震神器”问世!能抵消80%地震能量(图)

2017-09-13 08:47:13   央视财经

原标题:厉害了!我国“抗震神器”问世!能抵消80%地震能量!还有。。。

今年的8月8日,四川九寨沟发生7.0级地震,相隔一天,新疆博尔塔拉州精河县又发生6.6级地震。

作为自然界中毁灭性最高的灾害之一,人们谈及地震就会为之恐慌,近来,一种可以让建筑物抵销80%地震能量的“抗震神器”问世了,而且这种“抗震神器”还是利用火箭发动机的原理研发出来的,火箭和抗震神器,这到底是怎么结合到一块儿的?

航天科技四院80%收益来自民品资源共享共同发展

8月的最后一天,位于陕西省渭南市的大荔县实验小学迎来了孩子们开学前的报到日。

让孩子们除了迎接他们的新老师、新同学还有崭新的、高标准的教学楼。这所占地80亩的大荔县实验小学洛滨校区于两个月前刚刚竣工,三栋教学楼能够容纳3600名学生。之所以说建筑标准高,是因为在每一栋教学楼的下面增添了一种神秘的建筑部件-“隔震支座”,是建筑抵抗地震的有效装备。

孩子们报到的同时,中国航天科技集团四院41所的唐春昱和赵新男打开了教学楼的一处通风口,下到建筑的底部。隔震支座每6米一个,呈网状分布,在这个地下空间有30个,支撑着整栋教学楼,同时肩负起抗震的工作。

中国航天科技集团四院41所固体火箭发动机首席专家尤军峰:地震波最厉害的就是横波,地面是横向摆动。瞬间这个楼房就会倒塌。

传统的抗震技术是把建筑物上部结构和基础牢固地连接在一起,就是把房子盖得更结实,用更粗的钢筋、更多的混凝土浇注,但这样抗震效果并不理想。而隔震支座则是在上部结构与地基之间增加隔震层,安装橡胶隔震支座,起到与地面的软连接,通过这样的技术,可以把地震80%左右的能量抵消掉。而这样的抗震技术竟然来源于火箭发动机。正是研发火箭固体发动机的设计师们研发了这项技术。

位于陕西西安城郊的一处工厂内,炼胶师祁向礼开始对炼好的橡胶像揉面一样进行挤压。祁向礼炼的这种橡胶延伸率高达600%,能达到航天级橡胶的材质要求。反复挤压是为了让橡胶里的配方充分融合,制作完成的隔震支座能做到与建筑同寿命,没有发生地震不用更换,而橡胶配方正是航天人的得意之作。
