AI Technical Summary

Technical Problem

Existing bridge construction methods, such as segmental construction and use of trough-shaped longitudinal beams, result in high resource consumption, complex joint formation, and slow construction progress, particularly for bridges with larger span widths.

Method used

A method involving prefabricated, thin-walled longitudinal beams with a hollow box cross-section and deck slab elements, where joint gaps are minimized and reinforced with connecting reinforcement embedded in concrete, allowing for rapid construction with reduced resource consumption.

Benefits of technology

Enables the rapid construction of bridges with spans ranging from 25 to 60 meters, reducing resource consumption and enabling efficient use of cranes, while maintaining structural integrity and load-bearing capacity.

Abstract

The manufacture of a construction section of a bridge includes: providing two longitudinal beams made of reinforced concrete or pretensioned concrete; installing the two longitudinal beams at the installation site; providing deck slab elements; placing the deck slab elements onto the two longitudinal beams; laying reinforcement on the deck slab elements and over the cover plates of the longitudinal beams; applying the topping concrete onto the deck slab elements and the cover plates of the longitudinal beams to form the deck slab; repeating the operations to manufacture another construction section of the bridge; wherein one joint gap between two adjacent longitudinal beams, above a portion of the base plate, there is installed a longitudinal reinforcement that crosses the one joint gap and there is formed a layer of concrete over the base plate in the area of the longitudinal reinforcement.
