On The Distribution Program For Precast Beams Yard Of Railway Passenger Dedicated Lines

In our country, railway as the artery of the national economy,is the backbone of the dominant position in the transportation system.With rapid development of urban economy and the continuous improvement of population mobility, people have more and more high demand for the railway transportation in time and the capacity. The improvement of the high-speed rail technology meets the city's economic development and population liquidity problems to some extent. High speed railway is a collection of the most advanced railway technology,operational management, marketing and financing is very complicated system engineering, it includes infrastructure construction, locomotive vehicle configuration, station car operating rules and other content.Passenger dedicated line as one of the main content of the high-speed rail,for stable and safe operation, convenient maintenance, and the principle of passenger riding comfort, mostly on route choice model is given priority to with Bridges, in order to facilitate the site construction and management, usually adopt the method of centralized prefabrication and erection of the site. Precast girder erection quality and production speed directly affects the quality of the whole project and time limit for a project,therefore,railway passenger dedicated line the stand or fall of precast beams field planning and production management in the engineering construction plays a very important role.At present, our country planning and production management of precast beam field value is relatively weak,most site construction personnel are based on years of industry experience,combined with qualitative analysis,only to meet the time limit for a project as the main target of railway passenger dedicated line precast beam field planning and production management. Field construction of precast beams with independence and single Pin ZhongXing production, more professional type of work well together,alternate construction,great influenced by environmental conditions,is not gathered some mechanical equipment can make the project built and labor force,but to follow the objective law,reasonable arrangement for construction,be orderly, safe and economic to implement construction project quality,time limit and cost objectives.Combined with engineering practice experience, this article through to the railway passenger dedicated line of precast beams pre-planning influence factors such as location, layout and construction scale carries on the analysis comparison,and on the basis of the results of beam in field production technological process and the influence factors of field construction management analysis comparison,calculated the passenger dedicated line of precast beam field planning and production planning optimization combination,to ning an railway passenger dedicated line based on the actual construction of tongling sunan beam field analysis and evaluation,thus this article conclusion and provide some reference for the construction of the subsequent beam field, change the management of the construction personnel habits,the railway passenger dedicated line of precast beams field construction management level to further improve.
