Quality inspection method of hydraulic structures based on BIM

Abstract

The invention relates to the technical field of engineering construction, in particular to a quality inspection method of hydraulic structures based on BIM, comprising the following steps: a true three-dimensional real scene model of a plant area is established based on a tilt photography method of an unmanned aerial vehicle; lightweight 3D real-time model is imported into BIM cloud platform for color difference analysis, and the analysis results of concrete structure leakage and seepage flow are presented in BIM cloud platform; outputting analysis results containing actual coordinates and field images. Compared with that prior art, Its advantages are: Based on the tilt photography method of UAV, with the ability of fast collection, the real-time three-dimensional model of sewage treatmentplant area is established, which truly reflects the concrete structure status of the site, and the high-score image shows its texture. Compared with the traditional manual query method, it is more efficient, can query in a large range in a short time, and avoids the safety risk of manual query.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a BIM-based quality inspection method for hydraulic structures. Background technique [0002] BIM, namely "Building Information Model", can be translated as "Building Information Model". A building information model is a digital representation of the physical and functional characteristics of a facility. Building information modeling is a new tool for architecture, engineering and civil engineering. It uses the relevant information data of construction projects as the basis of the model to establish a building model, and simulates the real information of the building through digital information simulation. . It has five characteristics of visualization, coordination, simulation, optimization and plotting. [0003] For municipal sewage treatment plant projects, there are many individual structures, complex structures, and many detailed structures, involving lea...

Problems solved by technology

[0003] For municipal sewage treatment plant projects, there are many individual structures, complex structures, and many detailed structures, involving leakage in expansion joints, construction joints, and settlement joints; crack leakage between wall-penetrating pipes and concrete; pool walls Leakage caused by the unreasonable waterproof structure of the formwork opposite the pull bolts; leakage caused by unreasonable waterproof layer outside the pool wall; leakage and seepage of the sewage treatment structure caused by various construction conditions cannot be discovered in time. It will affect the water treatment quality of t...
