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.
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. Dubai 950 MW photothermal photovoltaic power plant collector tower by Shanghai Electric EPC general contract, China Construction three bureau two company construction general contract.
\"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.
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.
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.
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 \".
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.
