The Hassan 4X600MW clean coal-fired power station project in Dubai ushered in a key node – the main truss steel structure of the dry coal shed of No. 1 coal storage yard was capped 10 days ahead of schedule, and the total steel consumption was equivalent to that of the Eiffel Tower in Paris.
In accordance with international standards and environmental protection requirements, Hassyan aims to equip two coal storage yards with triangular tube trusses and pull-down cable structures. The structure is light and beautiful, taking into account economics. The steel structure of the entire coal storage yard is strictly in accordance with international standards for structural design, material procurement, processing and construction acceptance.
According to reports, in accordance with international standards and environmental protection requirements, Hassyan aims to match two coal storage yards, using triangular tube trusses, pull-down cable structure, light and beautiful structure, taking into account economics. The steel structure of the entire coal storage yard is strictly in accordance with international standards for structural design, material procurement, processing and construction acceptance. After the completion of the coal storage yard, the length of the single coal storage yard is 677 meters, spanning 122 meters, covering an area of 83,000 square meters, equivalent to the area of 12 standard football fields; the steel consumption is about 8,100 tons, and the total weight is with the Eiffel Tower in Paris. Quite, the high-strength steel zipper has a total length of 7,800 meters; the single-chassis coal yard has a coal storage capacity of 570,000 tons, which can meet at least two 600,000-kilowatt units for 45 days of continuous full-load operation.
Since May 2017, Harbin International Dubai Hashan Project Department has gathered experts and strengths to overcome difficulties in structural design optimization, supply chain management, and construction speed. In terms of design, according to the most stringent wind load parameters, the wind tunnel test was successfully passed in the German laboratory, which was unanimously recognized by the owners, the Dubai Municipal Government and all parties.
At the supply chain end, the project department innovated the supply chain management system and adopted the international standard quality real-time management and control. The entire coal storage yard maintained a high-quality, high-capacity shipment during the production of 8100 tons of steel structure, and it was completed in only 4 months. Shipped. In terms of construction, before the construction, strict construction simulation calculation and 3D construction scheme display, and overcome the unfavorable factors such as high temperature in Ramadan, and at the same time overcome a large number of welding work problems, the welding capacity of a single coal storage yard steel structure is about 59,000 welds. Quite a boiler on-site welding equivalent, more than 300 Chinese and foreign workers, more than 100 machines, high-speed flow hydration welding assembly, hoisting, lasted 8 months, under the zero non-conformity record, high-quality high-speed propulsion construction progress, 10 days earlier than originally planned A major node of the 56-inch main truss cap of the coal storage yard was completed.
The whole process construction of the Hasin project coal storage yard not only fully demonstrates the capabilities of Chinese design and manufacturing in China, but also demonstrates the ability and level of Harbin International to construct large-scale complex projects integrating design, procurement, manufacturing and construction. Going to the Middle East and even the global high-end power market, Chinese technology “going out” and Chinese companies to enhance their international image have played a role in brand demonstration.
