Visited Jiangxi province collapsed power core: fallen steel thicker than arm | | | power plant of Jiangxi province collapsed _ news

On November 24 at about 7:40, Yichun, Jiangxi province, the third-phase expansion project in fengcheng power plant level d section cooling tower crane collapsed. As of 24th at 22 o'clock, confirmed the accident site 74 people were killed and two others wounded.

This reporter has learned, after reported death toll was 67, number change is attributable, according to the rescue headquarters explained, is because more aid before, preliminary statistics summary results are not accurate. With the progress of rescue, collect, come to 74 deaths figure.

　　Journalists entering the core collapse of steel thicker than arms

Search-and-rescue after the reporter entered the scene of the accident in core. The collapsed area is 5000 square meters, according to the usual 100 square meters of housing, the collapse of houses in an area equivalent to 50. The entire circuit of the cooling tower is 400 meters, which is equivalent to the circumference of a circle the playground, from the model of the whole plant as you can see, two cooling towers accounted for one-fourth of the area of the entire plant, can see this project on the scale of local importance.

Model of power plant

I am sure you have a question, why the accident death rate is so high?

CCTV reporters Jia: "cooling towers along the height from the ground is almost more than 70 meters, the height of the average more than 25 floors of the building. Part time workers on the ground, and partly in cooling towers, whether it is falling from the height of a 25-story building, also was hit by something fell from the 25-story building, this impact is not everyone can afford. ”

As you can see, out of these steel, thicker than a human arm are crooked, rescue teams had to use hydraulic shears cut these structures to begin the rescue.

Jiangxi province Yichun City Fire Brigade Chief of staff Wang Gufeng: "after we arrived on the scene, using sniffer dogs, unmanned aerial vehicles and life detectors, 5000 square meters of collapse site for search and rescue. Scene divided into 7 job, each job rotations and two rescue groups work. ”

CCTV reporters Jia: "in accordance with the previously developed plan, collapse rescue force 5000 square meters of carpet the area of search and rescue. ”

Chief of staff Wang Gufeng: "on 24th 8:10, completing seven comprehensive search and rescue search and rescue region, 24th, 10:31, fully cleaned up. ”

　　Surviving workers tell horror moment: more than 10 minutes of platform collapse

It is understood that the two surviving workers on 24th at around 9 in the morning were sent to Jiangxi fengcheng city people's Hospital, between the age of 45-59, are people in Gansu province, there is no life danger.

"I don't know what happened, after I run scared silly. "Currently workers survived the accident treated Wang Yao-Sheng said. He was also at the scene, hospital care for several of his coworkers recalled the moment of panic.

24th just after 7 o'clock in the morning, they get to cooling tower, over more than 10 workers, are zero and the early handover. Above their heads more than 70 meters high, build a construction platform, there are also dozens of workers. About five minutes later, they suddenly heard a shout from above, then see the scaffolding fall, hit fallen water tower and secure channel. On the ground floor of workers ran outside into the cooling tower. Just more than 10 minutes of the period, the entire construction platform collapsed completely.

"When construction platform lifts, collapsed. In addition to coworkers in the surface layer, above all fall, steel material down below. "Wang Yao-Sheng said.

Wang Yaolong said of workers managed to escape from the ground floor, ground floor workers to escape from every day but two people were injured, mostly from Tianshui city, Gansu province.

　　Cooling tower has been built up to when the accident happened more than 70 meters

Background information to learn about the accident again. Full name of the site of the accident was "the third-phase expansion project in fengcheng power plant", is a key project in Jiangxi province, for this project, a total investment of 7.67 billion yuan.

Construction unit was company Jiangxi fengcheng of Jiangxi province for three power plants, general contractor is South China power engineering consulting group electric power Design Institute Ltd, main construction unit comprised of 4 companies bid for construction.

Accidents by Hebei billion to smoke Tower d standard engineering works limited, cooling tower and chimney construction projects. Hebei billion to smoke Tower Engineering Limited is specialized in cooling towers, chimneys, environmental engineering construction and project of a company. Cooling tower of the accident in April this year to start the construction, plans to build an altitude of 156 metres. When accidents occur, cooling towers have been building to more than 70 meters.

According to industry experts, is hyperbolic cooling tower construction, buildings belonging to the complex type. Cooling tower and thin wall construction platforms follow construction progress uplift.

Suspect the accident was caused by no standards for concrete strength

Construction of Hebei Yi feng Cheng Gao Shichao project Department staff said to the media, suspect incidents "may be caused by no standards for concrete strength". For the duration of construction experience, concrete has dried up, the morning of 24th, workers began tearing down the cooling towers of wooden scaffolding outside. But because of the bad weather, concrete and not dry like a thought, and thus has not been dry concrete starting off, finally collapsed. However, this claim has yet to be investigated.

探访江西坍塌电厂核心区:倒掉的钢结构比手臂粗|江西|电厂|倒塌_新闻资讯

　　11月24日7时40分左右，江西省宜春丰城电厂三期扩建工程D标段冷却塔平桥吊倒塌。截止到24日晚上22点，确认事故现场74人遇难，两人受伤。

　　记者了解到，此前报道的遇难人数是67人，之所以会发生人数的变化，按照救援指挥部的解释，是因为之前救援力量较多，初步统计汇总的结果并不准确。随着救援的进展，汇总各方情况，才得出74人死亡的数字。

　　记者进入核心现场 倒掉的钢结构比手臂粗

　　搜救基本结束后记者进入到了事故核心现场。整个坍塌面积是5000平方米，按平常的住宅100平方米一套，坍塌面积相当于50套普通住宅。整个冷却塔的周长是400米，这相当于操场一圈的周长，从整个电厂的模型可以看到，两个冷却塔占了整个厂区四分之一的面积，从规模上就能看得出这个工程对当地多么重要。

电厂模型

　　大家肯定有一个疑问，为什么这次事故的死亡率这么高？

　　央视记者贾林：“冷却塔的上沿距离地面高度差不多是70多米，这个高度相当于普通楼房的25层以上。当时有一部分工人在地面作业，有一部分是在冷却塔上面，不管是从25层楼的高度掉下来，还是被从25层楼掉下来的东西砸到，这个冲击力都不是普通人能承受的。”

电厂工地坍塌核心现场

　　现场可以看到，倒掉的这些钢结构，比人的胳膊还粗，都已经歪歪扭扭的，救援队当时得用液压剪剪开这些结构才能开始救援。

倒掉钢结构比人的胳膊都粗

　　江西宜春市公安消防支队参谋长王谷峰：“我们到了现场以后，利用搜救犬、无人机和生命探测仪，对5000平方米的坍塌现场进行搜救。救援现场分成7个作业面，每个作业面两个救援组进行轮换作业。”

　　央视记者贾林：“按照事先制定好的方案，救援力量对塌方的5000平米面积进行了地毯式搜救。”

　　参谋长王谷峰：“24日晚上8点10分，完成七个搜救区的全面搜救，24日晚上10点31分，对现场全面清理完毕。”

　　幸存工人讲述惊恐一刻：十几分钟平台全坍塌

　　据了解，两名幸存工人在24日早上9点左右被送到江西丰城市人民医院，年龄是在45到59岁之间，都是甘肃人，目前没有生命危险。

　　“不知道发生了什么，我逃出来以后就吓傻了。”目前在接受治疗的事故幸存工人王摇胜表示。他和当时也在现场、现在医院照顾他的几名工友回忆了那惊恐的一刻。

　　24日一早刚过7时，他们10多位工友就到达冷却塔内，进行零班与早班的交接。在他们头顶上方70多米的高处，搭建有施工平台，那里还有几十名工人。大概五分钟后，他们突然听到头顶上方有人大声喊叫，接着就看见上面的脚手架往下坠落，砸塌水塔和安全通道。在地面层工作的工人迅速往冷却塔外跑。短短十几分钟的时间内，整个施工平台完全坍塌下来。

　　“当时上下施工平台用的电梯，一起坍塌了。除了地面层的工友，在上面的人全部坠落，被钢筋等材料压在下面。”王摇胜说。

　　从地面层成功逃生的工人王耀龙说，地面层的工人除了两人受伤外都安全逃生，他们主要来自甘肃天水市。

　　事故发生时冷却塔已建至70多米

　　再来了解一下这次事故的背景信息。发生事故的工地全称是“丰城电厂三期扩建工程”，是江西省重点工程，本期工程投资总额76.7亿元。

　　建设单位是江西赣能股份有限公司丰城三期发电厂，总承包单位是中国电力工程顾问集团中南电力设计院有限公司，主体施工单位分别由4家公司分别中标建设。

　　发生事故的是由河北亿能烟塔工程有限公司负责的D标段工程，即冷却塔与烟囱施工项目。河北亿能烟塔工程有限公司，是专业从事冷却塔、烟囱、环保工程建设施工及项目改造的一家公司。发生事故的冷却塔今年4月份开工建设，计划建设高度156米。发生事故时，冷却塔已建设到70多米。

　　据业内专家介绍，冷却塔是双曲线建设工程，属于复杂的建筑种类。冷却塔外壁薄，施工平台跟随施工进度抬升。

　　怀疑事故是混凝土强度没达标造成

　　施工方河北亿能丰城项目部工作人员高士超对媒体说，怀疑事故“可能是混凝土强度没达标造成的”。为赶工期，施工方依经验，觉得混凝土已经干了，24日早上，工人们便开始拆除冷却塔外围的木质脚手架。但是由于天气原因，混凝土并没有像所想的那样干透，于是尚未干透的混凝土开始脱落，最后坍塌。不过，这一说法还有待调查。
