Problems solved by technology

However, for the excavation measurement of irregularly curved tunnels, it is obvious that conventional instruments and methods are very difficult. Even so, the measurement accuracy cannot meet the requirements. Improper measurement accuracy and measurement methods often lead to ineffective and low Efficiency, and will cause waste of materials and costs

Embodiment 1

[0047] (1) After the construction drawings of the irregularly curved tunnel to be constructed are completed, create a BIM model with LOD400 accuracy level according to the construction drawings and the overall topographic drawings of the mountain where the irregularly curved tunnel to be constructed is located. The BIM model must meet the LOD400 accuracy Grade requirements, a model that meets and reflects information on construction drawings. The software used to create the model is not limited to Autodesk Revit software and its series of auxiliary software products. According to the requirements of modeling convenience and flexibility, various forms of BIM software can be used.

[0048] In the Autodesk Revit software environment, according to the measurement and positioning information provided by the construction drawings, mark the positioning points on the BIM model with LOD400 precision level, and input the measurement data. Export the BIM model with LOD400 precision level...

Abstract

The present invention provides a method for measuring irregularly curved tunnels, by creating a BIM model with an accuracy level of LOD400; and using three-dimensional holographic scanning technology to scan the overall terrain of the construction site, collect three-dimensional point cloud data information, and create a three-dimensional point cloud Then, the BIM model and the 3D point cloud model are fitted and analyzed to obtain deviation data; the BIM model is revised to make the BIM model fully match the 3D point cloud model; finally, the BIM model is input into the terminal equipment of the BIM pay-off robot , control the BIM wire-laying robot to complete the measurement, wire-laying, and positioning of the tunnel construction work, and complete the measurement work of the irregularly curved tunnel construction. The method for measuring irregularly curved tunnels of the present invention can perform measurement operations on irregularly curved tunnels, has high measurement accuracy, simple measurement operation, high measurement operation efficiency, ingenious design, simple operation, low cost, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction measurement, in particular to the technical field of tunnel engineering construction measurement, in particular to a measurement method for irregularly curved tunnels. Background technique [0002] With the continuous advancement of civil engineering construction technology, in the field of infrastructure: the construction and development of high-speed rail, expressway and other projects, especially in the construction process of high-speed rail and expressway projects in mountainous areas, it is inevitable that tunnel excavation will be encountered. During the excavation process, how to ensure that the tunnel is constructed according to the construction drawings without large deviations is one of the difficulties in the measurement work during the tunnel construction process. [0003] At present, the traditional measurement method uses laser collimator, theodolite, level, t...
