城市跨线桥置换梁改造施工技术

Construction Technology of Displacement Beam Reconstruction of Urban Span Bridge

随着道路交通流量的逐步增加,部分现状道路的通行出现了能力不足的情况。因此,道路的改扩建已成为重要的研究方向,其中跨线桥加宽扩容则为重点施工内容。在佛山市某跨区的改扩建工程项目施工中,考虑到车辆通行、整体美观感等多重要求,根据某节点跨线桥的实际情况予以改造,采用换梁法操作,探讨具体的作业要点,旨在为类似项目提供参考。

With the gradual increase of road traffic flow, the capacity of some current roads is insufficient. Therefore, reconstruction and expansion has become an important breakthrough direction, in which the widening and capacity expansion of the bridge is the key construction content. In the construction of a cross-district reconstruction and expansion project in Guangdong city, considering the multiple requirements of vehicle passage and overall beauty, according to the actual situation of a node span bridge, the paper uses the beam replacement method to discuss the specific operational points, in order to provide reference for similar projects.
