库区大跨度连续梁施工关键技术

Key construction technologies of large-span continuous beam in water

以某库区连续梁桥为例,介绍了连续梁桥钢管桩基础施工、基础上横梁架设、单桩预压、预拱度设置、梁体施工和预应力张拉等内容,解决了水中钢管桩支架高、跨度大、预压不方便的问题,为类似工程施工提供了借鉴。

Based on a continuous bridge in water as an example, introduced the construction of pile foundation, erection of beam on the foundation, pile preload, camber settings, construction of beam and prestressed tension, etc. , it solved the problem of support that is so tall, span that is so large and preload that is inconvenient. It provided a reference for the similar construction.
