Secret that you don't know China, China-made "flood artifact"-flood, rainstorm, flood-IT information
Envy is the so-called "flood artifact"? That's because you don't know how much equipment made in China Bull. Underwater robot real-time monitoring of water regime, water-filled rubber Zidi quickly "turned" into a mobile wall of water, pillow covers new sandbag water swelling the size of ... ... In the recent floods in the South, groups of specialized rescue equipment put into use, become sophisticated in the floods "floods artifact." Xinhua News Agency reporter in the flood-fighting front line for you to reveal these "artifacts".
Secrets of flood-ravaged Chinese-made "flood artifact"
Responding to natural disasters, as well as science and technology first. Past, shipwrecks, heavy truck plug breached even by sea and flood "hand-to-hand combat", is the last resort for them. And now, depending on the terrain, River, flow velocity and flow trends, responding to different burst, piping, rescue teams will take a different approach. Professional rescue equipment inputs, making floods more precise and efficient.
"Artifact:" water water "folding of the moving wall of water"
Wangjiang County in Anhui Province, Wu Jiuwei rescue scene, hydropower force of armed police for the first time using the new major flood storage facilities-"water-filled rubber Zidi." Reporter in site see, rescue soldiers each 6 people a group, quickly spread rubber bags, with magic posted will more paragraph rubber Zidi connection, received Sheung Shui valve Hou flood fast into rubber bags in the, package Shang nursing Tan cloth, then with fixed pile will Zidi fixed, not to 20 minutes, a "to water water" of long 12 meters, and high 0.7 meters of rubber Zidi on "built" has up.
This equipment is also known as "mobile folding wall of water", the outer layer is strong and wear-resisting layer of high-strength canvas, which is impermeable rubber bladders. Portable compressed State, where there is a danger where you can move to; when using local materials, water weight as gravity to break containment. Advantages of speed, high efficiency, reusable, not afraid of water rush, can greatly improve the efficiency of emergency, effective flood control dam in danger.
"Artifact II: such as the" thousand-hand Bodhisattva ", and" walk "the intelligent excavator"
Reporters in jinzhai County, Anhui Province following the hydropower force of armed police involved in rescue operations when, late at night under the searchlight, dozens of large excavator operation, arm raised, another fall like the "thousand-hand Bodhisattva". In addition, length 20 m long jib excavators, "walk" of Walker, the unmanned intelligent excavator have been put into use, making different terrain and different forms of aid are guaranteed.
Poyang break sealing operations, a Digger hundred hands over more than 500 relief troops only 47 hours to complete the break seal. Sealing the break with 24,600 square filling, filling sandbags is about 700,000, or by "human wave" shoulder hand-carried, is impossible.
"Artifact III: the flood of" old objects "improved upgrade from the" new weapon ""
In the flood scene, reporters noted, when more than 10 people to carry up Tin boat now "turned" rubber assault boats to operate two people; heavy soil easily destroyed sandbags, have gradually been replaced by professional sandbags for flood control. Light and compact new sandbags stacked up, only hundreds of grams of weight is only a pillow size, once the water within 35 minutes of rapid expansion can be compacted. Not shipped filled with sand and distance carried, plugging breaches relief troops of field operations, saving significant time and energy, and improve the efficiency of emergency rescue and disaster relief.
Should burst its banks, with big load since truck of input using, can load near hundred tons of steel cage series, effect than sank car, and wreck blocking burst good have more; processing tube Chung, General first do surrounding well, now with plate, and hard quality plastic surrounding well of way instead of sandbags surrounding well, past 3 meters diameter of surrounding well to 20 people 3 hours to completed, now 4 a people 30 minutes on can get.
"Artifact-four:" foot root "combination of steel and wood debris dams (cofferdam)"
China-made "flood artifact" steel wood combinations of soil and stone dam (cofferdam), is made with wood trusses, hit on the dike burst "root", then truss space filled with sandbags, while filling the upper soil material formed to Qi, current carry debris to burst cofferdam can hole the size gradually blocked.
China Institute of water conservancy and hydroelectric power Research Institute for flood control and drought relief said Ding Liuqian, closing when the water flow is too large to completely fill, otherwise they will be derided swept away directly, truss "root" to support, it is established, the water can flow, borrow frame filled with sandbags and sandbag will not be washed away. This approach is consistent with the flow characteristics of science.
Fighting floods: sophisticated equipment revealed "machinery of beauties"
"Troops with shovels, pickaxes and woven bags, us to shoulder a bag a bag carrying, LEGO dams......" armed police corps Deputy Political Commissar Shi Zhiqiang of the MEW remembers more than 10 years ago, the Yangtze River, the nenjiang River and the Songhua River Valley when the flood occurred, they bubble in Zhaoyuan, Daqing reservoir flood-fighting experience. Now, as technology advances, use of human wave and flood "melee" and even army arm jumping into close up a breach in the flood scene will be less and less.
Break mouth at, ET walking type excavator and various heavy loaded mechanical armored battle; flood in the, charge boat search-and-rescue transfer was trapped masses, radar speed instrument, and water Xia robot real-time monitoring water changes; mountain collapsed site, snake eye, and radar detector implementation precision search-and-rescue; air, no machine not continuous return disaster image and related data, for Headquarters experts discussion relief programme; tied Shang life jackets and rescue material of no machine also can in was flood siege of masses above precision "dropped"......
Has long been engaged in construction and rescue, with advantages of hydropower force of armed police personnel, equipment and technology, in today's flood operations, increasingly appreciate the power of technology, the mechanical beauty.
In the flood-fighting front line, Youyang County Lakes danger is the hydropower troops used six-rotor UAV survey found. They finished in only 2 hours damming upstream within 1 km of the three-dimensional laser scan operations and underwater imaging system and system of slope deformation damming field 360-degree panoramic image data for effective disposal of danger provides first-hand information, gain valuable time.
In Guizhou province Dafang County, physico-chemical Xiang partial slope village Venus Group occurred mountain landslide, more than 40 hours day and night kept of rescue in the, soldiers using excavator and current most advanced of full terrain emergency rescue car and the Sonic, and radar, professional equipment, take "mechanical mainly, and artificial supplement, and by layer stripping, and light dug slow into, and opening cover search" of tactics on lost joint personnel for search, until found mountain landslide last one lost joint who.
Scientific research power and efficient rescue and relief
In floods, in addition to the broad masses of party members and cadres and the masses, the PLA and the armed police force has always been a main force of the flood, and the commandos, bears flood disaster risk heavy tasks. In the context of major river basins across the country, there are 19 Corps as the main flood of national professional emergency forces.
According to PLA's flood control engineering research center expert Chen Yunhe introduced, these forces are equipped with vehicles, command boats, boat fuck machines, plant and other special equipment and equipment for flood, carrying station close to area emergency task, plugging breaches, water rescue, dams, explosion flood has played an important role in major flood operations.
In addition, previous experience participating in the flood, and the flood control technology research based on experience, have become an important support efficient rescue and relief.
In recent years, as a professional rescue teams armed police targeted task needs of hydropower engineering troops and frontier areas, organizational strength of Earth and stone, metal structure, blasting remove danger engineering such as six rescue technology research and scientific and technological research, summarizes and explores Lake, grid, such as fast-erecting more than 50 kinds of tactical warfare.
Chen Yunhe introduces our army had carried out a "vacuum-surcharge preloading applied in the dam for flood control to quickly deal with research" and "caisson closing emergency research" research. Among them, the "dam safety key technology and research" project awarded the 2015 national science and Technology Advancement Award.
揭秘那些你所不知道的中国中国国产“抗洪神器” - 抗洪,暴雨,洪水 - IT资讯
羡慕别人有所谓的“抗洪神器”？那是因为你不知道中国制造救援装备有多牛。水下机器人实时监测水情、充水式橡胶子堤可迅速“变身”成移动堵水墙、枕巾大小的新型沙袋遇水自动膨胀……在近期的南方抗洪救灾现场，一批批专业救援装备投入使用，成为抗洪抢险中的高精尖“抗洪神器”。新华社记者在抗洪一线为你揭秘这些“神器”。
揭秘洪水肆虐中的中国国产“抗洪神器”
应对自然灾害，也需要科技先行。过去，以沉船、沉卡车堵决口，甚至以人海与洪水“肉搏”，是不得已而为之。现在，根据不同的地形、河道、流速和水流走势，应对不同的决口、管涌，救援队伍会采取不同的办法。专业救援装备的投入，使抗洪抢险更加精准、高效。
【神器一：“以水治水”的可折叠移动堵水墙】
在安徽省望江县伍玖圩抢险现场，武警水电部队首次运用了新型专业防洪抢险储备设备——“充水式橡胶子堤”。记者在现场看到，救援官兵每6人一组，迅速铺开橡胶袋，用魔术贴将多段橡胶子堤连接，接上水阀门后洪水快速流入橡胶袋中，包裹上护坦布，随后用固定桩将子堤固定，不到20分钟，一道“以水治水”的长12米、高0.7米的橡胶子堤就“筑”了起来。
这种装备又被叫作“移动折叠式堵水墙”，外层是结实耐磨的高强度帆布层，里面是不透水的橡胶水囊。压缩状态时轻便易携，哪里有险情就可以搬到哪里；使用时可就地取材，用水的自重作为重力进行溃口围堵。优点是速度快、效率高、可重复使用，不怕浪打水冲，可极大提高抢险效率，有效控制洪水漫坝险情。
【神器二：如“千手观音”、可“抬腿走路”的智能挖掘机】
记者在安徽省金寨县跟随武警水电部队参与救援行动时看到，深夜的探照灯下，几十台大型挖机同时作业，机械臂一只扬起，另一只落下，犹如“千手观音”。此外，臂展20米的长臂挖掘机、能“抬腿走路”的步履式挖掘机、无人驾驶的智能挖掘机相继投入使用，使得应对不同地形、不同形式的救援都有保障。
在鄱阳溃口封堵作业中，一台挖掘机能顶百双手，500余名救援官兵仅用47小时完成溃口封堵。封堵溃口用的2.46万方填筑料，装沙袋大概是70万个，如果还是靠“人海战术”肩扛手抬，根本不可能实现。
【神器三：抗洪“老物件”改良升级成的“新武器”】
在抗洪现场，记者注意到，当年十几个人才能扛起来的铁皮冲锋舟，如今“变身”橡皮冲锋艇两个人就能操作；笨重易毁的土质沙袋，也逐渐被专业防汛沙袋取代。轻便小巧、自重只有几百克的新型沙袋叠起来只有一块枕巾大小，一旦遇水三五分钟内就可迅速膨胀压实。不用装填沙土和远距离扛运，救援官兵可现场操作封堵决口，大大节约了时间和体力，提高了抢险救灾效率。
应对决堤，随着大载重自卸车的投入使用，可载重近百吨的钢筋笼串，效果比沉车、沉船堵决口好得多；处理管涌，一般先做围井，现在用钢板、硬质塑料围井的方式代替沙袋围井，过去3米直径的围井要20人3个小时才能完成，现在4个人30分钟就能搞定。
【神器四：“脚下生根”的钢木土石组合坝（围堰）】
中国国产“抗洪神器”钢木土石组合坝（围堰），就是用钢木做成桁架，打到溃口下面的堤口上“生根”，再在桁架空间内用沙袋填充，同时在上游抛填土料形成地碶，水流将土石带至溃口围堰时就可以将大小孔眼逐渐堵住。
中国水利水电科学研究院防洪抗旱减灾研究所所长丁留谦说，堵口的时候水流太大不能完全填满，否则会直接冲散冲垮，先做桁架“生根”能够支撑、立稳，水也可以流动，在用沙袋借框架结构填充，沙袋不会被大水冲跑。这种方法符合水流的特点，比较科学。
抗击洪灾：高精尖装备显现“机械之美”
“部队带着锹、镐和编织袋，大家一袋一袋地肩挑背扛，把堤坝加固垒高……”武警水电部队一总队副政委史志强清楚记得十几年前长江、嫩江、松花江流域发生特大洪水时，他们在大庆肇源库里泡水库的抗洪经历。如今，随着科技进步，利用人海战术与洪水“肉搏”，甚至子弟兵手挽手跳进洪水中堵住决口的场景将越来越少。
溃口处，ET步履式挖掘机和各类重装机械铁甲上阵；洪水中，冲锋舟搜救转移被困群众，雷达测速仪、水下机器人实时监测水情变化；山体坍塌现场，蛇眼、雷达探测仪实施精准搜救；半空中，无人机不间断回传灾情图像和相关数据，供总部专家讨论救灾方案；拴上救生衣和救援物资的无人机还能在被洪水围困的群众上方精准“空投”……
长期从事水电施工和抢险救援，拥有人才、装备和技术优势的武警水电部队，在如今的抗洪抢险作业中，愈发体会到科技之力、机械之美。
在抗洪一线，重庆酉阳堰塞湖险情就是水电官兵利用六旋翼无人机勘察时发现的。他们仅用2个小时就完成了堰塞体上游1公里范围内的三维激光扫描作业，并利用水下成像系统和边坡变形系统构建了堰塞体现场360度全景图像数据，为有效处置险情提供了第一手资料、赢得了宝贵时间。
在贵州省大方县，理化乡偏坡村金星组发生山体滑坡，40多个小时昼夜不停的救援中，官兵利用挖掘机和当前最先进的全地形应急救援车及声波、雷达等专业设备，采取“机械为主、人工为辅、逐层剥离、轻挖慢进、揭盖搜寻”的战法对失联人员进行搜寻，直到找到山体滑坡最后一名失联者。
科研成果助力高效抢险救灾
在洪水肆虐中，除了广大党员干部和群众，解放军和武警部队历来是抗洪抢险的主力军和突击队，承担着抗洪抢险的急难险重任务。在全国主要江河流域范围内，有19支以工程兵部队为主体的抗洪抢险国家级专业应急部队。
据解放军防汛抢险工程技术研究中心专家陈云鹤介绍，这些部队都配有指挥车、指挥艇、操舟机、植桩机等抗洪抢险专用装备与器材，担负着驻地临近地区的应急抢险任务，在封堵决口、水上救护、堤坝加固、爆破分洪等重大抗洪抢险行动中发挥了重要作用。
除此之外，历次参与抗洪抢险的实战经验，以及基于经验的防汛抢险技术装备研究成果，都成为高效抢险救灾的重要支撑。
近几年，作为专业救援部队的武警水电部队瞄准任务需要和前沿领域，组织力量开展了土石方类、金属结构类、爆破类工程排险等六类抢险技术课题研究和科技攻关，总结探索出堰塞湖处理、电网快速架设等50多种战术战法。
陈云鹤介绍，我军还开展了“真空堆载联合预压在防汛堤坝快速处理中应用研究”和“沉箱堵口抢险技术研究”等课题研究。其中，“水库大坝安全保障关键技术与研究”项目获得了2015年国家科学技术进步一等奖。
