基于工业化建造思想的标准化预应力管道研发

Research and Development of Standardized Pre-stressed Pipe Based on Industrial Construction Ideas

预应力管道是体内预应力实现的基本构件,目前普遍应用的金属波纹管和塑料波纹管在使用过程中也暴露了诸多缺点。从工业化建造的要求出发,研究了一种新型智能预应力管道,包括锚头组件、标准管道组件、连接接头组件、索力测量组件和密实度测量组件五个部分。在完成了标准化设计之后,研究了这种新型预应力管道在T梁、板梁、小箱梁等中小跨径桥梁上的应用。新型预应力管道在提高施工质量的同时,节约了时间和人工成本,对于实现桥梁施工和管理的信息化、智能化、绿色化有很好的促进作用。

The pre-stressed pipeline is the basic component of the realization of internal pre-stressing. At present, the commonly used metal bellows and plastic bellows have exposed many problems in the process of use. From the requirements of industrial construction, a new type of intelligent pre-stressed pipeline is studied including five parts of anchor component, standard pipe component, joint component, cable force measurement component and density measurement component. After standardized design, the application of this new type of pre-stressed pipe in short and medium span bridges of T-beam bridge, plate girder bridge and small box girder bridge is studied. The new type of pre-stressed pipe saves the time and labor cost at the same time improves the construction quality, and is good for promotion of realizing the informatization,intelligentization and greenization of bridge construction and management.
