Abstract

The invention relates to a steel box truss arch bridge mounting, positioning and monitoring integrated construction method, and belongs to the technical field of bridge engineering measurement construction, because a first prism device is already mounted on a monitoring point before a chord member is hoisted, when the chord member is hoisted, a measurer only needs to use a measuring instrument onthe ground to measure a first actual node coordinate at a chord member node, measurement positioning is realized, and the measurer does not need to hold a prism by hand to measure a steel box truss arch bridge from a middle rod; and the first actual node coordinates are substituted into the constructed spatial axis model to calculate the linear parameters of the steel box truss arch bridge, and the position of the chord member is adjusted to be hoisted according to the linear parameters so that the deformation monitoring and linear monitoring of the arch rib can be realized without moving thenode coordinates forwards or backwards and converting node deviation. Therefore, the measurement precision and the measurement efficiency can be improved, the measurement cost is reduced, and the safety in the measurement process can be improved.

Description

technical field [0001] The application relates to the technical field of bridge engineering measurement and construction, in particular to a construction method integrating installation, positioning and monitoring of a steel box truss arch bridge. Background technique [0002] Because the steel box truss arch bridge is not only suitable for crossing rivers and canyons and other mountainous valleys and complex terrains, but also suitable for bustling urban areas such as urban river crossing bridges, and has a beautiful appearance, it is widely used in bridge construction. Among them, the steel box truss arch bridge can not only be erected by cantilever single chord, but also can be hoisted in a segment or inter-segment, and if the navigation conditions are satisfied, it can also be hoisted in the whole segment. However, no matter what method is used to erect the steel box truss arch bridge, its linear change needs to be monitored to ensure the structural quality and safety of...
