Large-radian overflow surface complex structure reinforced concrete bridge and dismantling method

Abstract

The invention belongs to the technical field of bridges, and particularly relates to a large-radian overflow surface complex structure reinforced concrete bridge and a dismantling method. The method comprises the steps of: support designing and machining, support installing, arch rib and wind brace dismantling, bridge deck dismantling, middle span main beam and cross beam dismantling and side span main beam and cross beam dismantling, wherein the support designing and processing step comprises support designing and support processing. The dismantling construction method is suitable for any terrains, operation can be carried out under the conditions that the terrains are complex and large-scale construction machines cannot enter a site for construction, according to existing construction conditions, computer finite element software is used for designing a support form, and stress analysis is calculated. Compared with traditional construction methods, the method is low in cost and safe, the construction period is easy to guarantee, and the construction process of the construction method has small pollution influence on the environment and has creativity.

Description

technical field [0001] The invention belongs to the technical field of bridges, and in particular relates to a reinforced concrete bridge with a complex structure on a large arc overflow surface and a demolition method. Background technique [0002] In recent years, with the development of the construction industry and the continuous improvement of people's architectural aesthetics, for tourist cities, characteristic buildings are even more unique, which can highlight local characteristics and attract tourists' attention. For this reason, the earliest batch of concrete bridges were demolished due to backward workmanship, resulting in quality defects and inconspicuous shapes, and new bridges that met local development requirements were rebuilt. [0003] Traditional demolition methods have the disadvantages of high cost, great environmental damage, long construction period and high cost. In view of the above situation, a new bridge demolition method is urgently needed to chang...
