Research On The Key Resources In The Construction Of The Large-steel Structure In Non-slideway

With the rapid development of the construction industry, the application of large-steel structures becomes more and more widely. The scale of the construction becomes huger. And the construction of steel structures also tends to modular construction. Koniambo Nickel project was one of the projects which used modular construction technology in the world. This project had a total of 17 large-steel modules, and the heaviest one was about 5.00×106 kg. Because of the limit of outside environmental factors and the construction conditions, the steel module in the nickel-mining project was built in a non-slide area, which greatly limited the successful construction of large-steel modules.This paper gives analysis and discussions about the key resources in the construction process of the large-steel structures, such as field resource, the large-steel modules, the steel deck-plates and the key machines and tools used in construction; certain optimization of these resources were made. The main contents of this paper are as follows:1. Under the premise of expounding on key steel-structures'construction, the key resources in the construction process were significantly analyzed, and the critical importance of resource management was explained.2. By analyzing the construction site layout, the multi-level decision-making was proposed; by applying the fuzzy evaluation theory, the evaluation theory of construction site layout based on multi-level decision-making was proposed.3. For the production of the steel deck-plates, based on the scanning-algorithm and TSP saving-algorithm, production allocation model was proposed, which made the production of the steel deck-plates be rationalized and the production efficiency be increased.4. Since the production equipment utilization in the construction of steel modules and prefabrication of steel deck-plates was not so high, the production model based on the production efficiency was proposed to reduce idle time in the production process and improve the production efficiency.5. Through the analysis of site layout and the production of steel module and deck-plates, we knew the most frequent-used large-scale equipments in the construction process--which are tower crane, crawler crane and proposed methods to optimize the use of these machines. Moreover, for the confliction in construction, we proposed a scheduling model based on value coefficient.In summary, the management of large-scale resources in the steel modules' construction was optimized in some extent in this paper. By these methods, the construction of the large-steel structure would be completed smoothly. And these methods in this paper have certain significance to the actual projects.
