Abstract

The invention provides a bridge reconstruction method, which belongs to the technical field of bridge construction, and comprises the steps that two sets of arch rings are built below an original bridge floor, the two sets of arch rings are arranged at intervals along the trend of a river channel, the two sets of arch rings are respectively positioned on the two sides of a plurality of rows of piers, and the two ends of each set of arch rings are respectively fixed on river levees on the two sides of the river channel; a supporting beam is built between each pier and the two sets of arch rings; the supporting beams penetrate through the bridge piers and the two sets of arch rings in the horizontal direction; and the part of the pier below the supporting beam is dismantled to suspend the pier. The invention provides a bridge reconstruction method, and aims to solve the problem of how to reasonably reconstruct a water-blocking bridge.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and more specifically relates to a bridge reconstruction method. Background technique [0002] With the continuous development and expansion of the city, higher requirements are put forward for the flood control of urban rivers. Through field investigation, it is found that the substructures such as piers and caps of many bridges need to occupy part of the flood flow area of ​​the river, thereby increasing the It reduces the local water flow resistance, blocks and retards the water flow, and has a water blocking effect on the river flow. Seriously affected the safety of river water flow, causing flood hazards. [0003] In the prior art, bridges with severe water resistance are usually demolished, and then new bridges are re-planned to meet urban flood control standards. However, this technical means is costly and has a long cycle, which affects urban traffic and causes bridges that ...
