Toll stations are not just places to collect car tolls at intersections, but to a large extent serve as the city's business card. Therefore, the design of toll booths must not be careless, especially the toll booths at the entrance of the city should be done as a face-saving project.
The coal storage yard is a key environmental protection project of Xinji No. 1 Mine, a key project that determines the safe and green development of the mine in the future, and a key environmental control project of China Coal Group and Xinji Company.
Arthur Vierendeel, born in Leuven, Belgium, is a university professor and civil engineer. The vierendeel structure he developed is named after him. Therefore, the scientific name of the hollow truss is also called Vierendeel truss.
The axis size of the space frame shed for coal storage yard is 120m (1-16 axis) * 300m (A-Q1 axis), and the height is 45.2m.
Taking (Indonesia) Boya 2 × 660 MW pithead power station supporting coal storage yard dry coal shed space frame project installation as an example, this paper focuses on the hoisting new technology and new method of the more dangerous space frame project, and the hoisting wire rope is carried out. The safety force check calculation is carried out, and effective analysis and verification are carried out for the structural hoisting under different working conditions at each stage. The hoisting process mainly includes the beginning of the space frame installation, the use of 50 t crawler cranes and 25 t truck cranes to cooperate with the space frame to continue to extend across the bucket turbine, the support is in place, the support position space frame expansion installation and subsequent space frame installation and other key processes .
