Key Technology for Construction of Steel Composite Section of I-steel Composite Beam—Taking Chongqing Shuitu Jialing River Bridge as an Example

Abstract

The rapid installation and positioning construction of the steel-concrete joint section of the I-steel composite beam cable-stayed bridge is one of the main beam construction technologies of the I-steel composite beam cable-stayed bridge. It is mainly used for the rapid installation and positioning construction of the steel-concrete joint section of the I-steel composite beam cable-stayed bridge, with significant social benefits. Compared with the similar technologies in China, its innovative achievements make the rapid installation and positioning construction technology of the steel-concrete joint section of the I-steel composite beam cable-stayed bridge more capable of adapting to the complex environment, as the new technology greatly improves the installation and positioning construction time of the steel-concrete joint section of the I-steel composite beam cable-stayed bridge, reduces the cost, has stronger competitiveness, promotes the scientific and technological progress and development of the industry, and has outstanding social benefits.
