【摘要】：本文对新建德大铁路铺架工程面临的难题,通过对指导性施工组织设计的分析和研究,结合本段工程的实际特点和难点,综合分析了影响本工程的各种制约因素,确定了适应本段工程的铺架总体施工组织方案。首先着重论述了铺轨架梁总体施工方案及铺架基地与既有京沪铁路的接轨方案,加强铺架基地和制存梁场等大型临时设施的建设,主要采用大型机械化生产的施工模式,结合人工换铺的施工工艺,合理安排铺架基地与既有铁路的接入时机,详细叙述了铺架运输问题的解决。其次对预应力铁路混凝土T型桥梁的预制存放、轨排生产与铺设、桥梁架设、桥梁横向连接、推送(换铺)长钢轨、钢轨焊接、上砟整道、应力放散与锁定等主要施工工艺进行详细的阐述,并提出与本工程适应的劳动力组织和机械配置方案,同时也提出了铺架过程中协调组织与配合工作的重要性。通过总结,进一步强化施工组织及施工方案的重要性,积累新建铁路铺架工程施工经验,提高协调能力,提升铺架施工综合水平。文章主要由以下几个部分的内容组成：(1)介绍了新建德大铁路铺架Ⅰ标段的工程概况及总体施工组织方案。(2)针对新建德大铁路铺架基地的设置、与既有线接轨实际情况及铺架顺序安排,成立了适合本项目的桥梁、轨排、长轨条、道碴运输组织机构,制定了有针对性的行车组织计划和安全保障措施。(3)详细阐述了轨排拼装采用固定台位式生产线,采用反锚法进行轨枕锚固、人工轨排拼装工艺。铺轨架梁采用TJ165铁路专用架桥机、WZ500-TY长轨推送设备、DTC160t自行式转盘车调头设备,基本实现了铺架工期目标。(4)详细阐述了轨道工程的各种施工机具、施工程序和施工方法,科学组织,合理确定人员、机械进场数量和时机,确保在规定的时间内架桥机和长轨推送车交替不间断施工。(5)详细阐述了长轨条的施工方法及单元轨节的焊接工艺,制定了无缝线路应力放散、锁定等施工方案。
[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.
