中国为什么会被世界称为“基建狂魔”?看看这些名场面就明白了。
9小时改造火车站 马斯克惊叹
“基建狂魔”的速度有多快?眼睛一闭一睁,9个小时过去了,一座火车站改造完了。
这座一夜之间“换血”的火车站是福建龙岩火车站,由中铁四局施工。2018年1月19日18:30,随着现场总指挥一声令下,1500余名工人同时上阵。要在9个小时内完成火车站的大改造,施工时间非常紧张。
此次龙岩站站改拨接施工为I级封锁施工,共包含4个龙口,7个拨接工作面3组道岔拆除、3组道岔插铺的施工。机器轰鸣、火星四溅,密密麻麻的工人有条不紊分工协作,画面犹如电影大片。
最终,1月20日凌晨2点多,经过近9个小时的紧张奋战,工人们圆满完成了道岔拆铺、拢口拨接、信号换装I级施工,龙岩站站改拨接顺利完成,漳龙铁路、赣龙铁路、赣瑞龙铁路、新建南龙铁路顺利接入龙岩站新站房。
龙岩站9小时完成大改造。 中铁四局供图龙岩站站改拨接是南龙铁路管线内最大的一次拨接,此次拨接为南龙铁路开通奠定了基础,南龙铁路建成通车后两地通行时间缩短至1.5小时。
9小时改造火车站的场面让世界再次为中国速度折服。美国企业家埃隆•马斯克也在社交媒体上为其点赞,并感慨:“中国在先进基础设施上的发展要比美国快100多倍!”
8小时拆完589米立交桥
“基建狂魔”的速度有多快?眼睛再一闭一睁,8个小时过去了,589米长的立交桥拆没了。
一夜之间被拆除的是江西南昌龙王庙立交桥。这座立交桥建于1992年,在2017年被拆除时已经“服役”了25年。
之所以要拆掉它,是因为这座立交桥属于“单纯式”立交,随着南昌交通的发展,龙王庙立交桥已经不能满足车辆通行的需要。所以,要拆除旧桥建新桥。
但是拆桥困难重重,该桥位于主城区,交通流量大,不能长时间封闭,总工期不到60小时,工期极其紧张,而且工程量大,全桥长589米,宽16米,最高处达7.6米,同时地下管线复杂,施工稍有不慎就会对沿线1000多户居民用水用气造成影响。
但这难不倒“基建狂魔”,中铁四局派出了200余台挖掘机同时作业。在桥两侧一字排开的挖掘机伸出长臂,就如一只只蚂蚁,努力啃食钢筋水泥,拆除现场蔚为壮观。最终,一夜之间这个庞然大物就消失了。
南昌龙王庙立交桥进行拆除作业现场。中铁四局 供图“中国效率”又一次惊艳世界。英媒不禁感叹:“这就是我们所说的效率!”
“基建狂魔”创造的名场面还有很多:
在重庆,上演五桥同转的“空中芭蕾”,5座全长383.5米、总重达21500吨(相当于1.5万辆小汽车)的大跨度混凝土梁式桥梁,完成88度的转体,最终实现精准对接。
在厦门,3万吨客运站“走起来”平移了288米,还来了个90度转身,成功上演最牛“搬家”。
在武汉,10天建成火神山医院,12天建成雷神山医院,让世界再次见识到中国的基建速度。
在东南沿海,“基建狂魔”集结两万多名建设者,建成55千米长的港珠澳大桥,这是世界最长的跨海大桥。
在西北沙漠,仅用时三年多建成和若铁路,“圈住”了塔克拉玛干沙漠,将和田群众出疆路程缩短1000多公里。
逢山开路、遇水架桥,“基建狂魔”的成绩有目共睹,他们不断连通,将全国各地连为一体。
这十年来,高速铁路营业里程由不到1万公里增加到4万公里,高速公路里程由9.6万公里增加到16.9万公里,让中国拥有了全球最大的高速铁路网、高速公路网。
“基建狂魔”为什么这么快?
这些不可思议的名场面,“基建狂魔”是怎样创造的?
参与一夜拆除立交桥项目的中铁四局洪都大道总工程师李青杠认为,中国基建速度之所以这么快,一是中国基础设施审批工作效率高,从立项到审批、建设,各部门全力推进。二是中国有强大、全系统的制造业,基础设施建设所需的原材料资源丰富。三是科技引领力不断增强,工艺工装创新不断加快工程建设速度。
中国基建,标定中国速度。“基建狂魔”,擦亮强国底色。(完)
中新网评:处理核污水绝不是日本自家私事****** 中新网北京1月19日电(蒋鲤)日本政府近日称,将于2023年春夏期间开始向海洋排放经过处理的福岛第一核电站核污水。日本罔顾国内民众及周边国家的屡屡反对,企图将核污水“一倒了之”,把一件关乎全球海洋生态环境和公众健康的事当成了自家私事。 资料图:日本福岛第一核电站。2011年,福岛核电站事故发生后,大量放射性物质泄漏到大气层和太平洋,对周围环境造成了难以逆转的伤害,数十万人被迫撤离该地区。时至今日,作为日本邻国之一的韩国仍未解除福岛海鲜禁令。 日本以核污水存储能力即将达到上限为由,在2021年4月13日,正式决定将福岛第一核电站核污水排入太平洋。过去一年多,日本政府和东京电力公司一直在持续推进核污水排海计划。 日本政府辩称,这些核污水经多核素处理系统(ALPS)处理后很安全,甚至“可以喝”,这样的表态无疑在愚弄大众。 事实上,经过处理的核污水仍含有多种放射性物质,核污水一旦排放入海就无法回收,长期来看,将会给海洋生态带来难以估量的潜在威胁,最终危害人类健康。 因此,核污水排海计划推出后,遭到日本民众强烈反对。日本《朝日新闻》2022年3月公布的问卷调查显示,福岛县、宫城县和岩手县受访的42个市町村长中,约六成反对东京电力公司福岛第一核电站核污水排放入海。日本全国渔业协会联合会也多次申明立场,反对该计划。 日本政府认为,核污水排海是最便宜、最省事的解决方案,但此举却将周边国家乃至全世界置于核污染风险中。太平洋非日本一家之海,核污水会随着洋流流动,其影响势必会跨越国界,危害周边国家乃至整个国际社会的公共福祉和利益。 《韩国经济新闻》发文称,相关研究认为,福岛核污水如果排放入海,约7个月后将到达济州等韩国海域,该国水产业和旅游业将遭受相当大的损失。 德国南极海洋机构也曾发出警告,若日本将所有核污水排入海中,不到半年,整个太平洋都将面临高度辐射威胁,包括远在大洋另一端的美国。太平洋地区人民更是对日本该计划持反对意见。 日本作为《联合国海洋法公约》缔约国,有义务保护海洋环境。然而,在核污水排海方案的正当性、核污水数据的可靠性、净化装置的有效性、环境影响的不确定性等问题上,日本未能作出科学、可信的说明。 国际原子能机构技术工作组虽已三次赴日实地考察评估,但尚未就日排海方案的安全性给出结论,并且对日本提出诸多澄清要求和整改意见。在此情况下,日本仍执意推进核污水排海工程建设,这是极不负责任的行为。 太平洋不是日本的下水道,日本必须正视各方合理关切,在与周边国家等相关利益方和国际原子能机构充分协商后,制定合理的核污水处理方案。日本也要着眼长远,若只顾眼前,执意将核污水排放入海,不仅其自身,周边国家乃至全世界都将为之买单,其后果必将会危害数代人。 Fukushima water disposal by no means Japan’s own business By John Lee (ECNS) -- Japan has announced it will release treated wastewater from the wrecked Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean this year. Although Fukushima wastewater disposal affects global marine ecological environment protection and public health, Japan has turned a deaf ear to domestic and international opposition to dumping the contaminated water into the sea, treating the "global" matter as its own business. The Fukushima accident in 2011 had sent large quantities of radiation into the atmosphere and the Pacific Ocean, causing irreversible damage to the surrounding environment, and hundreds of thousands of people were forced to evacuate the area. South Korea still maintains its import ban on Japanese seafood from areas affected by the Fukushima nuclear disaster. On April 13, 2021, Japan announced it had decided to discharge contaminated radioactive wastewater in Fukushima Prefecture into the sea due to dwindling storage space, with the Japanese government and plant operator Tokyo Electric Power Company Holdings Inc. promoting the release plan over the past year. The Japanese government argues that the water treated by an advanced liquid processing system, or ALPS, is safe and drinkable, which is undoubtedly fooling the public. In fact, the treated wastewater still includes a variety of radioactive substances and can’t be recycled once discharged into the sea, which will pose a great threat to marine ecology and ultimately endanger human health in the long run. Therefore, the discharge plan has been strongly opposed in Japan. According to a questionnaire conducted by The Asahi Shimbun, nearly 60 percent of mayors of 42 municipalities in Iwate, Miyagi and Fukushima prefectures oppose the discharge plan. The National Fisheries Cooperative Federation of Japan has also repeatedly stated its opposition in public. The Japanese government believes that dumping Fukushima wastewater into the sea is the cheapest and most convenient solution, but neighboring countries and even the whole world will be at risk of nuclear pollution. The Pacific Ocean doesn’t belong to Japan and the wastewater flow along oceanic currents will surely break boundaries and endanger public welfare and the interests of neighboring countries and even the international community. The Korea Economic Daily reported that related research concluded that if contaminated water from Fukushima is released into the ocean, it would only take seven months for the contaminated water to reach the shores of Jeju Island, with the country's aquaculture and tourism suffering considerable losses. According to the calculation of a German marine scientific research institute, radioactive materials will spread to most of the Pacific Ocean within half a year from the date of discharge, and the U.S. and Canada will be affected by nuclear pollution. People in the Pacific region also oppose the discharge plan. As a participant of the United Nations Convention on the Law of the Sea, Japan has the obligation of protecting the marine environment. However, it hasn’t offered a full and convincing explanation on issues like the legitimacy of the discharge plan, the reliability of data on the nuclear-contaminated water, the efficacy of the treatment system or the uncertainty of environmental impact. Though the IAEA has yet to complete a comprehensive review after three investigations in Japan, the Japanese side has been pushing through the approval process for its discharge plan and even started building facilities for the discharge. It is rather irresponsible for Japan to act against public opinion at home and concerns abroad. The Pacific Ocean is not a private Japanese sewer. The country must seriously heed the voices of the international community and make a reasonable plan for the Fukushima wastewater disposal after full consultation with stakeholders and international agencies. If it only seeks instant interest and insists on discharging the contaminated water into the sea, not only itself, but also its neighboring countries and the entire world will pay for the decision and several generations will be forced to bear the consequence.
