Description

Technical Field

[0001] This utility model belongs to the field of bridges and relates to a monitoring and auxiliary system, specifically a three-dimensional motion monitoring and auxiliary system for bridge rotation construction. Background Technology

[0002] With the increasing density of road networks, bridge construction requires more frequent crossings of existing roads. Traditional methods not only easily disrupt the safety and normal operation of existing lines but also affect the progress of bridge construction. Therefore, the bridge rotation construction method has emerged. Compared with other construction methods, the bridge rotation method can significantly reduce the impact on daily traffic on existing lines while ensuring the safety and economy of the bridge. Currently, bridge rotation construction is widely used in bridge construction due to its unique advantages and has very broad development potential.

[0003] In recent years, with the continuous improvement of bridge construction technology, the bridge rotation method has emerged as a promising approach in bridge construction. This method offers advantages such as minimal disruption to existing traffic operations and is widely used in bridge engineering projects crossing existing lines (especially railways). The bridge rotation method involves assembling or casting the main structure near a predetermined axis, using prefabricated ball joint structures with low friction coefficients, and then rotating the completed main structure to the designed axis using a traction system. Compared to traditional construction methods, the rotation method can avoid unfavorable terrain and fully utilize the natural terrain conditions for on-site prefabrication and casting of components. This method ensures uninterrupted traffic flow across the line and uninterrupted navigation during construction, making the impact on existing traffic negligible. Therefore, this method guarantees maximum socio-economic benefits and offers advantages such as good construction quality assurance, high construction safety, simple and convenient construction process, and fast construction speed, significantly improving both socio-economic and technical benefits.

[0004] However, current automated monitoring technology for rotary construction in my country cannot meet the needs of engineering practice, and there is no standardized document that can be universally adopted by the engineering community, which restricts the application and further development of rotary construction monitoring technology. To promote the digitalization and networking of transportation infrastructure, accelerate the green transformation of transportation, guide the transformation and upgrading of highway construction, maintenance and management with digitalization, and integrate the concept of safe development into all aspects and the entire process of transportation development, thereby enhancing safety assurance capabilities.
