Automatic Measurement System for Bridge Girder Displacement [3D Bridge]

basic information

This is an automatic measurement system that manages the three-dimensional coordinates of the bridge girder position information using an automatic sighting total station, displaying the differences from the planned height. With real-time automatic measurement, there is no need to interrupt work for measurements. It allows for viewing the measured displacement data via a web browser (K-Cloud) from the site office PC or remote terminals. ● Direct comparison with design values Traditionally, bridge measurements were conducted manually using a level and staff for comparison with the design. By registering the design (planned) data in advance into the system, it enables direct and real-time comparison of the differences between the design values and the values during construction.

Applications/Examples of results

【Applications】 - Cantilever Method: By measuring the position of each step of the girder, the deflection status of the girder over time can be understood. - Launching Method: By measuring the position of the girder and the hand-stretching machine, the position of the girder during the launching process can be grasped. - Cable-Stayed Bridge Erection: By measuring the position of each step of the girder, the settlement status of the girder can be understood. This serves as a guideline when making adjustments with wires. - Crane Bent Method: By measuring the position of the girder during erection, the position of the girder after completion can be simulated based on temporary assembly data. - Cable Erection Direct Hanging Method: By measuring the position of the receiving beam and the wire pulley, the deformation of the bridge body during erection and the position of the girder can be confirmed. 【Examples of Achievements】 - Measurement of girder displacement associated with national highway superstructure work - Measurement of girder launching associated with expressway superstructure work - Measurement of girder displacement associated with PC superstructure work - Measurement of girder displacement associated with elevated bridge superstructure work
