Abstract

The invention relates to a construction method of a two-way curved arch bridge combined type reinforcing structure. The method includes the steps of (1) construction preparation, (2) arch rib surfacetreatment, (3) arch rib formwork arrangement, (4) arch sheet formwork arrangement, (5) pedestrian passageway supporting, (6) arch rib concrete pouring construction, and (7) arch sheet concrete pouringconstruction. The method has the beneficial effects that arch rib formwork installation and location accuracy can be improved, the integrity of a formwork structure can be effectively improved, and the formwork supporting construction difficulty can be reduced as well; the stress of an arch sheet formwork structure can be improved, and two-way location of an arch sheet formwork is achieved; the stress performance of the formwork structure can be improved as well, and the formwork supporting construction efficiency and quality are improved; and a pedestrian passageway structure is good in stress performance and wide in application range, and passageway installation and location efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a construction method for a compound reinforcement structure of a double-curved arch bridge that can improve the quality of on-site construction and the integrity of the construction structure, reduce the difficulty of formwork installation and positioning, and improve the efficiency of on-site construction. It belongs to the field of bridge engineering and is suitable for double-curved arch bridges Reinforcement works. Background technique [0002] With the increase of traffic volume, the strain and disease of arch bridges are becoming more and more serious. How to improve the quality of reinforcement construction of arch bridges, improve the efficiency of on-site construction, and save the cost of reinforcement construction are often problems that need to be solved urgently in the design and construction of reinforcement. [0003] In the prior art, there is a method for strengthening double-curved arch bridges with corrugated...
