Problems solved by technology

For some stone arch bridges, after the structural inspection and calculation, only some sections of the stone arch bridge have insufficient bearing capacity. If the entire section is reconstructed and repaired, it will lead to increased engineering volume, long construction period and high project cost.

Abstract

The invention discloses a method for strengthening the cross-section structure of the arch back of an old stone arch bridge. Construction - backfilling the arch filler and other steps, the old stone arch bridge arch back reinforcement method of the present invention can not only effectively improve the section strength of the stone arch ring, meet the design requirements for loading, but also maintain the original appearance of the bridge , reduce the damage to the old stone arch circle, reduce the amount and difficulty of construction work, save the cost, shorten the construction period, so that the reconstruction of the stone arch bridge can be carried out in a safe, efficient and environmentally friendly manner, which is in line with the concept of green construction and enriches the old stone arch bridge The transformation technology has good reference significance for similar projects.

Description

technical field [0001] The invention belongs to the technical field of bridge reconstruction and reinforcement, in particular to a reinforcement method for an old stone arch bridge with an enlarged cross-section structure. Background technique [0002] The stone arch bridge has a long history, good durability, and strong corrosion resistance. However, due to economic and technical limitations in design, the load level is low, and the rate of disease is relatively high, which affects the safety of the bridge. The structure of the stone arch bridge itself has a certain load-bearing potential. If it is well utilized, it will be repaired and reconstructed with appropriate methods to increase the safety of the road, and it will achieve good economic and social benefits. [0003] At present, there are many reinforcement methods for stone arch bridges. The common reinforcement methods for different diseases include enlarging the cross-section of the arch ring, pasting steel plates,...
