Open final of three gorges project "answer": vessels may have such dams | _ Three Gorges project news

18th, the last of three gorges project "answer" is about to be revealed! According to the Maritime Bureau of three gorges project NOTAM, 18th into the trial navigation of three gorges ship lift phase, this means that ship to climb after the three Gorges Dam, you can "lift"!


  "The elevator" technology, the scale of the dam creating the world


Three Gorges ship lift and two-way five-level ship lock for the three gorges project of the three gorges navigation structures, high lift height, lifting weight, large amplitude, the upper navigable downstream water level variation characteristics of speed, technical difficulty and is currently the world's largest shiplift.


On July 6, 2016, Yichang city, Hubei Province, the three Gorges dam of three gorges ship lift location.

  Lifting weight and height of the world's largest


Ship Chamber of three gorges ship lift may contain 3000 tons ship, Max climbed 15,500 tonnes GRT, the largest climbing height of 113 meters. Lifting weight and height, are the highest in the world.


  The world's largest and highest technical difficulty


Three Gorges ship lift line with a total length of about 5000 meters, the Chamber Chamber Tower building height is 146 metres, maximum lifting height: 113 m, maximum lift weight more than 15,500 tons, ship compartments 132 meters and width of 23.4 meters long, 10 meters high, can raise the 3000 ton ship over a dam. These data show the shiplift of three gorges project is the world's largest and highest technical difficulty shiplift project.


  Over time reduced from 3.5 hours to 40 minutes


Design of three Gorge lift-ship machine bearing ship main 3000-ton large passenger ferries, cruise ships, and part of rapid material carriers transporting fresh. After the operation, this type of ship and time will be shortened from now through the permanent ship lock of 3.5 hours for about 40 minutes. After running three gorges ship lift for cargo and special vessels providing fast dam channel.


  How do ships "elevator"?


If ships were to sail downstream to upstream of the dam –


The first ship in ship lift Chamber, close the ship Chamber downstream gate.



Ship lift Chamber rise by climbing device until the ship Chamber in the water level and water level in the reservoir in the upper reaches.



Open ship Chamber Head gate, ships sailed out of the ship lift Chamber into the upstream channel.



Ships from upstream to downstream, the process is reversed.


  Three Gorges shiplift postponed after 13 years and 8 years continued


As the world's largest water control project of three gorges project the last construction project, TGP last three Gorge lift-ship machine was known as the "answer". After 13 years of postponed and after 8 years of construction, on May 13 this year and September 13 respectively before the trial navigation and fire control acceptance, has put into operation conditions. According to the Ministry of transport of Yangtze River shipping administration of the trial navigation of three gorges ship lift work programme, in September 2016 onwards into the trial navigation of three gorges ship lift.



According to reports, the trial navigation will be divided into four stages. The first phase from September 18, 2016 2016 experimental end of the impoundment of three Gorges reservoir, three Gorge lift-ship machine running time 8 o'clock until 17 o'clock every day.


  How vessels crossed the three Gorges Dam now?



There are two lines of three gorges shiplock, the equivalent of two-lane on the highway, up-link first-down. Each line shiplock has 5 rooms, 6 handyman gate; Chambers adjacent ground elevation difference of 22.6 m, five Chamber staircase-shaped layout.


Is the first Chamber in the upper reaches, downstream is the Fifth Chamber. If ships were to sail from downstream to upstream – after the ship sailed into the Fifth Chamber, close the downstream miter gates, through the underground water conveyance system, Fourth Chamber v Chamber filled with water, when two Chamber awash, and visitors on the opening words, the ship sailed into the fourth lock Chamber. And so on, the ship is like climbing a staircase at the grade level, the first Chamber, to the waterway in the upper reaches of the dam. Process of shipping down instead.



A single lock Chamber of three gorges shiplock NET width of 34 metres and a length of 280 meters, is the world's largest Chamber can accommodate 6 3000-ton ship. A boat through the three gorges ship lock for about 3 hours.

揭三峡工程最后“谜底”:轮船可这样过大坝|三峡工程_新闻资讯

  18日,三峡工程最后的“谜底”即将揭晓!据三峡海事局航行通告,三峡升船机将于18日进入试通航阶段,这意味着,以后船舶要翻越三峡大坝,可以“坐电梯”了!


  “坐电梯”翻大坝 技术、规模创世界之最


  三峡升船机与三峡双线五级船闸同为三峡工程通航建筑物,具有提升高度大、提升重量大、上游通航水位变幅大、下游水位变化速率快的特点,是目前世界上技术难度和规模最大的升船机。


2016年7月6日,湖北省宜昌市三峡大坝的三峡升船机外景。

  提升重量和高度均为世界之最


  三峡升船机承船厢可载3000吨级船舶,最大爬升吨位达1.55万吨,最大爬升高度113米。提升重量和高度,均为世界之最。


  全球规模最大、技术难度最高


  三峡升船机全线总长约5000米,船厢室段塔柱建筑高度146米,最大提升高度为113米、最大提升重量超过1.55万吨,承船厢长132米、宽23.4米、高10米,可提升3000吨级的船舶过坝。这些数据都显示了三峡升船机是世界上规模最大、技术难度最高的升船机工程。


  过坝时间从3.5小时缩短为40分钟


  三峡升船机承载船型的设计定位主要适应3000吨级大型客轮、旅游船,及部分运送鲜活快速物资货船。运营后,这类船舶过坝时间将由现在通过永久船闸的3.5小时缩短为约40分钟。投入运行后,三峡升船机将为客货轮和特种船舶提供快速过坝通道。


  船舶怎么“坐电梯”?


  假如船舶要从大坝下游驶向上游——


  首先船舶驶入承船厢,关闭承船厢下游闸门。



  承船厢通过爬升装置上升,直到承船厢内水位与上游水库水位齐平。



  打开承船厢上游闸门,船舶驶出承船厢进入上游航道。



  船舶从上游向下游行驶,与其过程相反。


  三峡升船机经历13年缓建和8年续建


  作为世界最大水利枢纽三峡工程的最后一个建设项目,三峡升船机被誉为三峡工程最后的“谜底”。在经历了13年缓建和8年续建之后,于今年5月13日和9月13日分别通过试通航前和消防工程验收,具备投入试运行的条件。根据交通运输部长江航务管理局《关于三峡升船机试通航工作方案》,三峡升船机于2016年9月起进入试通航期。



  据介绍,试通航将分为四个阶段。第一阶段从2016年9月18日至三峡水库2016年试验性蓄水结束,三峡升船机运行时间每天8时至17时。


  现在船只如何翻越三峡大坝?



  三峡船闸有南北两线,相当于公路上的双车道,一线上行一线下行。每线船闸有5个闸室、6道人字闸门;相邻闸室地面高程相差22.6米,五个闸室呈楼梯状布置。


  上游是第一闸室,下游是第五闸室。假如船舶要从下游驶向上游——船舶驶入第五闸室后,关闭下游人字门,通过地下输水系统,第四闸室往第五闸室内充水,当两个闸室内水面齐平时,打开上游人字门,船舶驶入第四闸室。依此类推,船舶就好像爬过一级又一级楼梯一样,通过第一闸室,驶向大坝上游航道。船舶下行的过程相反。



  三峡船闸单个闸室净宽34米、长280米,是世界上最大的闸室,可同时容纳6艘3000吨级船舶。一艘船通过三峡船闸大约要3个多小时。
