Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in detail:

[0034] Such as Figure 1 to Figure 2 As shown, a kind of three-dimensional special-shaped bridge formwork assembly surveying method based on BIM technology that the present invention relates to comprises the following steps:

[0035] (1) Establishing a BIM model: According to the design drawings, the concrete veneer of the bridge is accurately modeled at 1:1 in Rhino software.

[0036] (2) 3D stakeout data export: Based on the established BIM model, use Rhino software to draw the structural feature points that need to be staked out, and then select the stakeout points according to the construction requirements, and then convert the selected stakeout points to 3D Batch export in coordinate form.

[0037] (3) Plane coordinate transformation: use the coordinate transformation formula to transform the plane coordinates, and use the UCS command mode in Aut...

Abstract

The invention relates to a BIM technology-based three-dimensional bridge template assembling measurement method, and belongs to the technical field of engineering measurement. The method comprises thefollowing steps of: establishing a BIM model; exporting three-dimensional lofting data; converting a plane coordinate; carrying out site lifting by a measurement robot; carrying out data acquisition;and importing the data into the model to carry out recheck. The method has the benefits of saving the measurement data calculation time and error rate, improving the three-dimensional special-shapedbridge template assembling measurement precision, enabling site piece and dislocation to be lower than standard requirements, saving a lot of construction cost, simplifying the measurement work content and improving the template assembling efficiency.

Description

technical field [0001] The invention relates to a three-dimensional special-shaped bridge template assembly and survey method based on BIM technology. Background technique [0002] At present, there is no application case for the combination of BIM technology and construction measurement in the domestic bridge industry, and there is little research on related technologies, especially for bridges with three-dimensional special-shaped structures, each of which has a changing shape. If traditional construction measurement methods are used, the following problems exist Big flaw: [0003] 1. The traditional coordinate and elevation calculation methods are very difficult to implement in three-dimensional special-shaped bridges and the accuracy is very low, which virtually increases the difficulty of measurement and stakeout errors, and cannot guarantee the construction quality. [0004] 2. Design drawings only provide two-dimensional CAD electronic drawings or paper drawings. Whe...
