Automatic Measurement System for Bridge Girder Displacement [3D Bridge]
Understand the height and position of the beam without interrupting the construction.
The NETIS number has been updated! KT-230145-A (3D Displacement Automatic Measurement Cloud Management System) *Old NETIS number: KT-130050-VE This is an automatic measurement system that manages 3D coordinates of the position information of bridge construction girders using an automatic aiming total station, displaying the difference from the planned height. With real-time automatic measurement, there is no need to interrupt work for measurement purposes. Displacement data measured can be viewed from a PC in the field office or from remote terminals via a web browser (K-Cloud).
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 and displays the difference from the planned height. With real-time automatic measurement, there is no need to interrupt work for measurements. Displacement data measured can be viewed from a PC in the site office or from remote terminals using a web browser (K-Cloud). ● Direct comparison with design values Traditionally, bridge measurements were conducted manually using levels and staffs to compare with the design. By registering the design (planned) data in advance into the system, it is possible to directly and in real-time compare 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 of the girder over time can be understood. - Launching Method: By measuring the positions of the girder and the hand-extended machine, the position of the girder during launching can be grasped. - Cable-Stayed Bridge Erection: By measuring the position of each step of the girder, the settlement condition 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 the 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 due to construction of national highway superstructure - Measurement of girder launching due to construction of expressway superstructure - Measurement of girder displacement due to construction of PC superstructure - Measurement of girder displacement due to construction of elevated bridge superstructure
