桥梁施工时的作业面难免与既有道路存在交叉的情况,桥梁施工关键节点则会影响到桥梁的总工期。以悬索桥锚碇的施工为例,在锚碇开挖工作面与道路结构交叉的情况下进行保通设计,选择合适的保通方案及在保通方案中采用不同的施工措施,对于工程的经济性及安全性的影响极为重要。针对桥梁工程施工关键节点与既有道路交叉的问题,提出保通设计方案及注意事项。
The working face of bridge construction inevitably crosses existing roads, and the key nodes of bridge construction will affect the total duration of the bridge. Taking the construction of the suspension bridge anchorage as an example, under the circumstance that the anchorage 碇 excavation face intersects with the road structure, the design of Bao Tong, the selection of suitable Bao Tong solution and the adoption of different construction measures in Baotong project are of great significance to the economic The impact of sex and safety is extremely important. Aiming at the problem that the key nodes of the bridge construction intersect with the existing roads, this paper puts forward the design schemes and precautions of the insurance maintenance.
