中新网武汉1月10日电(李坤岳刘昱希徐金波)此间中建三局二公司10日发布消息称,由该企业承建的阿联酋迪拜950MW光热光伏电厂集热塔当地时间9日封顶,该光热光伏电厂集热塔既是全球最大的光热光伏电厂,又是全球最高的集热塔工程。

Wuhan, january 10(li kunyue liu yuxi xu jinbo) in the construction of the third bureau two company on the 10th, the company said that the construction of the dubai, dubai, u.e.,950mw photovoltaic power plant, the top of the local time 9, the photovoltaic power plant is the world's largest photothermal photovoltaic power plant, but also the world's highest collection tower project.

迪拜950MW光热光伏电厂项目是迪拜水电局DEWA与沙特国际电力和水务公司ACWA联合开发的马克图姆太阳能园区第一阶段第四期太阳能发电项目。其中,集热塔是光热电厂的核心构筑物,是整个电厂的“心脏”。迪拜950MW光热光伏电厂集热塔由上海电气EPC总承包、中建三局二公司施工总承包。

The Dubai 950MW photothermal photovoltaic plant project is the first phase of the Maktum Solar Park Phase IV solar power generation project developed by the Dubai Hydropower Authority DEWA in conjunction with the Saudi International Power and Water Company ACWA. Among them, the collector tower is the core structure of the photothermal power plant and the \"heart\" of the whole power plant.

“迪拜光热电厂集热塔总高度260米,222米以下为混凝土结构,222米以上为集热器,结构部分混凝土量18000立方米,不仅是全球最高、最大的集热塔,也是全球工艺最复杂、技术难度最高的集热塔。”中建三局二公司海外分公司迪拜光热项目指挥长顾冬10日介绍。

\"The total height of the collector tower in Dubai Photoelectric Power Plant is 260 meters, the concrete structure is below 222 meters, and the structure part of the concrete is 18000 cubic meters, which is not only the highest and largest collector tower in the world, but also the most complex and technically difficult collector tower in the world. China third bureau two company overseas branch dubai photothermal project commander gu dong 10.

同时,迪拜当地常年高温,夏季室外温度达60摄氏度以上,冬季昼夜温差大,常年遭受沙尘暴危害。在沙漠腹地,温度的影响因素被成倍的放大,采取传统的滑模式连续施工,其混凝土凝控和温控问题将带来极大挑战。

At the same time, Dubai local perennial high temperature, summer outdoor temperature of more than 60 degrees Celsius, winter temperature difference between day and night, perennial exposure to sandstorms. In the desert hinterland, the influence factors of temperature are multiplied, and the traditional sliding-form continuous construction will bring great challenges to the concrete coagulation control and temperature control.

此外,该集热塔51米以下为方形结构,51米到82米为变截面段,82米到222米为圆形。解决直径米、可自由截面变换的滑模平台设计和制造问题,对于采用滑模施工工艺的光热造塔团队也带来了极大的困扰。

In addition, the heat collection tower below 51 m is a square structure,51 m to 82 m is a variable section, and 82 m to 222 m is round. To solve the problem of design and manufacture of sliding-form platform with diameter meter and free-section transformation, it also brings great trouble to the photothermal tower-making team using sliding-form construction technology.

为在恶劣环境中完成复杂施工,中建三局二公司自主研发了被称为“沙漠造塔机”的集热塔滑模平台。该“沙漠造塔机”自重200吨,由64台短行程液压千斤顶构成。千斤顶荷载达6吨,按大小进行排布,既能同步提升,又能适时变形移位,相继攻克了变形变径滑模平台不间断施工、大直径滑模平台精确同步顶升施工、超高温条件下滑模混凝土质量控制等六大技术“硬核”。

In order to complete the complex construction in the harsh environment, the third bureau and two companies of China Construction independently developed the sliding form platform of the collector tower called \"desert tower building machine \". The \"desert tower machine\" weight of 200 tons, by 64 short-range hydraulic Jack. Jack load up to 6 tons, according to the size of the arrangement, both synchronous lifting, but also timely deformation shift, has conquered the deformation variable diameter sliding-form platform uninterrupted construction, large-diameter sliding-form platform accurate synchronous jacking construction, high temperature under the sliding-form concrete quality control and other six technologies \"hard core \".

据悉,迪拜950MW光热光伏电厂集热塔是中国“一带一路”重点建设工程,丝路基金也参与到该项目投资中,使用全球最先进的技术以“世界最高标准”承建。建成后每年将产生70万千瓦清洁电力配备世界上最大的储热能力,能够为迪拜27万多家住户提供清洁电力,每年减少140万吨碳排放量。(完)

It is reported that Dubai 950MW photovoltaic power plant collector tower is China's \"Belt and Road\" key construction project, Silk Road Fund also participated in the project investment, using the world's most advanced technology to \"the world's highest standard\" to build. It will generate 700,000 kilowatts of clean electricity a year with the world's largest heat storage capacity, capable of providing clean electricity to more than 270,000 households in Dubai, reducing carbon emissions by 1.4 million tons a year.
