[Abstract]:Based on the analysis and study of the guiding construction organization design and the practical characteristics and difficulties of this section, this paper comprehensively analyzes the various restrictive factors that affect the project. The overall construction organization scheme of the frame is determined to suit this section of the project. First of all, the general construction plan of laying track beam and the scheme of connecting the laying base with the existing Beijing-Shanghai railway are discussed emphatically, and the construction of large-scale temporary facilities such as frame laying base and beam yard are strengthened, and the construction mode of large-scale mechanized production is mainly adopted. Combined with the construction technology of manual replacement, reasonable arrangement of the access time between the base and the existing railway is made, and the solution to the transport problem of the laying frame is described in detail. Secondly, prefabricated storage, rail production and laying, bridge erection, bridge transverse connection, push (replacement) long rail, rail welding, ballast whole track of prestressed railway concrete T-type bridge, The main construction techniques, such as stress releasing and locking, are expounded in detail, and the labor force organization and mechanical configuration scheme adapted to the project are put forward. At the same time, the importance of coordinating organization and coordination in the process of frame laying is also put forward. Through summing up, the importance of construction organization and construction scheme is further strengthened, construction experience is accumulated, coordination ability is improved, and comprehensive construction level is raised. This paper mainly consists of the following parts: (1) the general situation of the project and the overall construction organization plan of the frame laying section I of Xinjiande large railway are introduced. (2) aiming at the setting of the base of laying the frame of the Xinjian Deda railway, In line with the actual situation of the existing railway lines and the arrangement of the laying order, a bridge, rail platoon, long rail strip and ballast transportation organization suitable for this project have been set up. The relevant organization plan and safety measures are worked out. (3) the fixed platform production line is used for rail arrangement assembly, the reverse anchor method is used for sleeper anchoring, and the artificial rail arrangement assembly technology is discussed. TJ165 railway special bridge erection machine, WZ500-TY long rail pushing equipment, DTC160t self-propelled turntable turning equipment are used to lay track beam, which basically achieve the goal of laying frame. (4) various construction machines and tools for track engineering are described in detail. Construction procedures and construction methods, scientific organization, rational determination of personnel, number and timing of mechanical approach, In order to ensure the continuous construction of the bridge erector and the long rail push car in the specified time. (5) the construction method of the long rail strip and the welding technology of the unit rail joint are expounded in detail, and the construction scheme of the seamless track stress releasing and locking is worked out.
