The last riddle of the Three Gorges project is about to reveal that the ship can pass the dam.-pay.91860.net


The Three Gorges project finally announced the upcoming "mystery ship can live a dam this paper source: Xinhua new network 18, the Three Gorges project, finally the" answer "to be announced! According to the shipping notice of the Three Gorges maritime bureau, the Three Gorges ship lift will enter the trial navigation stage on the 18 th, which means that after that, the ship will have to take the elevator by crossing the Three Gorges dam. "The elevator" dam technology, scale and in the world and the Three Gorges ship lift with double line five grade ship lock for Three Gorges Project navigation structures, with large lifting height, lifting weight, Upstream Navigation characteristics of water level variation, the variation rate of the downstream water level quickly, is now the world’s largest ship and technical difficulty machine. In July 6, 2016, the Three Gorges ship lift on Three Gorges Dam in Hubei province Yichang city. The lifting weight and height are all the Three Gorges ship lift in the world. The carrier can carry 3000 tons of ships, the maximum climbing tonnage is 15 thousand and 500 tons, and the maximum climbing height is 113 meters. Increase the weight and height, all in the world. The world’s largest and highest technical difficulty of Three Gorges ship lift the entire length of about 5000 meters, boat cab segment tower building height of 146 meters, the maximum lifting height of 113 meters, the maximum lifting weight of more than 15 thousand and 500 tons, the ship chamber 132 meters long, 23.4 meters wide, 10 meters high, can lift the 3000 ton ship over a dam. These data show that the Three Gorges ship lift is the largest and most technically difficult ship lifting machine in the world. The time of crossing the dam is shortened from 3.5 hours to 40 minutes. The design positioning of the Three Gorges ship lift’s carrying ship is mainly suitable for 3000 ton large passenger ships, tourist boats, and some fresh and fast cargo vessels. After operation, the time of passing this kind of ship will be reduced to about 40 minutes by the 3.5 hour of the permanent ship lock. After the operation, the Three Gorges ship lift will provide a fast crossing channel for the passenger and freight wheels and special ships. How does the ship "take the elevator"? If the ship is to go upstream from the downstream of the dam – the first ship goes into the ship’s carriage and closes the downstream gate of the vessel. The ship’s carriage rises through the climbing device until the water level in the vessel is flat with the water level of the upstream reservoir. The upstream gate of the vessel is opened, and the ship goes out of the vessel into the upstream channel. The ship runs downstream from the upstream to the opposite of the process. 13 years of experience in the installation of Three Gorges ship lift and finally a construction project of 8 years as the world’s largest water conservancy construction of the Three Gorges project, the Three Gorges ship lift is regarded as the answer to the last "Three Gorges project". After 13 years of construction and installation for 8 years, in May 13th and September 13th of this year through the trial navigation before and fire engineering acceptance, have put into trial operation conditions. According to the Ministry of transport of the Yangtze River Waterway Bureau "on the Three Gorges ship lift trial navigation scheme", the Three Gorges ship lift in September 2016 trial navigation period. According to the introduction, the pilot navigation will be divided into four stages. The first stage from September 18, 2016 to the Three Gorges Reservoir in 2016 experimental storage, the operation time of the Three Gorges ship lift from 8 to 17 hours a day. How do ships go over the Three Gorges Dam now? The Three Gorges ship lock has two lines of North and south, which is equivalent to the two lanes on the road. Every line of locks has 5 chamber, 6 chamber of miter gate; the adjacent ground elevation difference of 22.6 meters, the five chamber is arranged in the staircase. Upstream is the first chamber, fifth chamber downstream. If the vessel from the downstream to the upstream — fifth ships into the chamber, close the downstream miter gate, through the underground water system, fourth to fifth chamber sluice chamber filled with water. When the two gate indoor surface normal Qi, open the upper miter gate, fourth ships into the chamber. By analogy, the ship like to climb a stair like level, through the first chamber, the dam to the upstream channel. The process of ship descending is opposite. The Three Gorges shiplock chamber single width of 34 meters, 280 meters long, is the world’s largest chamber, which can accommodate 6 3000 ton ship. It takes about 3 hours for a ship to pass through the Three Gorges Lock.

三峡工程最后“谜底”即将揭晓:轮船可以这样过大坝   本文来源:新华社 新蓝网   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。相关的主题文章:
