【摘要】：随着城市轨道交通工程的快速发展,U型梁越来越多的用于高架桥线路,U型梁结构形式新颖,截面尺寸多变,施工工艺较为复杂。因建设项目相对较少,施工经验缺乏,U型梁的预制、运输及架设施工工艺,需进行专项研究,进一步完善提升。本文以青岛蓝色硅谷轨道交通工程2#梁场为依托,从施工角度出现,充分挖掘施工细节,结合南京地铁2号线,上海地铁16号线等工程实例,从施工的角度展开,通过部分试验验证,进行全方位总结、优划,确定最优的U型梁制、运、架施工方案。施工设备直接决定所采取的施工方案,施工时尽量选有技术先进、安全可靠设备,通过提高机械化作业程度,减少人工操作,提高工程质量。特别是U梁的制、运、架作业,技术含量高,专业性强,选择合适的机械设备,事半功倍。文中详细研究了2#梁场施工中采用的全自动钢筋生产线、全液压内模、智能张拉系统、250T轮胎式提梁机、专用公路大件运输车、双导梁架桥机等设备。本文的主要内容为：1、结合现场实际情况,确定U型制梁场的规划设计。提出梁预制场的平面布置、制存梁台位设计、工装设备配置、临时设施的安排,可为不同条件下的梁场建设参考采用。2、U型梁预制技术研究：全自动钢筋加工生产线的研究,液压模板的设计及安拆,砼施工工艺,智能张拉系统的研究,桥梁场内移运技术,梁体外观质量控制,冬季施工技术等。3、运、架施工技术研究：运、架梁设备的选用,桥下公路及梁上运输方案,架桥机架梁方案,运、架梁过程中的安全技术措施。
[Abstract]:With the rapid development of urban rail transit engineering, more and more U-shaped beams are used in viaduct lines. Due to the relatively few construction projects and the lack of construction experience in prefabrication, transportation and erection of U-shaped beams, it is necessary to carry out special research to further improve the construction. Based on Qingdao Blue Silicon Valley rail transit engineering beam yard, this paper, from the construction point of view, fully excavates the construction details, combined with Nanjing Metro Line 2, Shanghai Metro Line 16 and other engineering examples, from the construction point of view, Through partial test and verification, summing up and optimizing layout, the optimal construction scheme of U-beam system, transportation and frame is determined. The construction equipment directly determines the adopted construction plan, and selects as far as possible advanced technology, safe and reliable equipment during construction. By improving the degree of mechanization, reducing manual operation, and improving the engineering quality. In particular, U beam system, transportation, rack operation, high technical content, professional, choose the appropriate machinery and equipment, twice the result with half the effort. In this paper, the fully automatic steel production line, hydraulic internal model, intelligent tension system 250T tire beam lifting machine, special highway large truck, double guide beam erection machine and other equipment used in the construction of beam yard are studied in detail. The main content of this paper is 1: 1. According to the actual situation in the field, the planning and design of U-shaped beam yard are determined. It is put forward that the plane arrangement of beam precast yard, the design of beam making and storing platform, the arrangement of equipment and temporary facilities can be used as reference for the construction of beam yard under different conditions, and the research on prefabrication technology of .2U beam can be used: the research of automatic steel bar processing production line. Hydraulic formwork design and installation, concrete construction technology, intelligent tensioning system research, bridge yard transport technology, beam appearance quality control, winter construction technology, etc. Transportation scheme of highway and beam below bridge, beam erection scheme of bridge erecting machine, safety technical measures in the process of transportation and erection of beam.
