【摘要】：宁波余慈高速公路为现今宁波市高速公路骨架路网里面的“三连”里面的“一连”。项目的建设路段总长度为6.202公里,根据高速公路的标准进行建设,项目设计的车辆行使速度为100km/h,双向四车道,全线高架总宽度为25.5m。论文首先阐述了普通现浇连续箱梁的施工策略,并站于设计的层面具体探讨了箱梁工程的特点。重点阐述了桥梁的大致情况、主要工程数量、本施工设计使用到的技术标准、技术条件、材料、项目设计以及施工的一些重点。以为项目的设计与施工方案的规划奠定基础。论文在设计分析上,详细介绍了本项目的具体施工组织设计情况,在项目施工组织方面具体概述了施工团队的布署、施工任务的具体规划、相关设备的配备、项目的施工进度布置等内容。在项目的技术策略上,论文先行阐述了工艺流程,之后具体阐述了地基的处理、搭设支架、支架预压、支立模板、钢筋工程、混凝土工程、梁体预应力体系施工、支架拆除等工艺。同是,综合概括了本项目在施工的时候使用到的质量保障策略与安全保证措施,同时更是论文研究的主要内容。论文经过对全项目的设计,施工与实施的具体内容与存在的问题,解决方法等进行了归纳与总结,并具体将项目施工进程中出现的各种问题进行阐述,总结了问题的原因与使用到的解决策略。希望可以为类似的项目施工控制作为参考之用。
[Abstract]:Ningbo Yuci Expressway is the "three links" in the present Ningbo Expressway skeleton network. The total length of the construction section of the project is 6.202 kilometers. According to the standard of the expressway, the speed of the designed vehicle is 100 km / h, the two-way four-lane and the total width of the whole line elevated is 25.5m. Firstly, the construction strategy of common cast-in-place continuous box girder is expounded, and the characteristics of box girder engineering are discussed in detail from the aspect of design. The general situation of the bridge, the quantity of the main projects, the technical standards, technical conditions, materials, project design and some key points of the construction are described. Lay the foundation for project design and construction plan planning. In the aspect of design and analysis, the paper introduces the concrete construction organization design of this project in detail. In the aspect of project construction organization, it concretely outlines the deployment of the construction team, the concrete plan of the construction task, the equipment of the relevant equipment. Construction schedule layout of the project, etc. In terms of the technical strategy of the project, the paper first describes the technological process, and then expounds the treatment of the foundation, the erection support, the preloading of the support, the supporting formwork, the reinforcement engineering, the concrete engineering, and the construction of the prestressed system of the beam body. Support removal and other processes. At the same time, it synthetically summarizes the quality assurance strategy and safety assurance measures used in the construction of this project, and it is also the main content of this paper. The paper summarizes the design, construction and implementation of the project, the existing problems, solutions and so on, and describes the various problems in the construction process of the project. The causes of the problem and the strategies used to solve the problem are summarized. It is hoped that it can be used as a reference for similar project construction control.
