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.

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 the entire sewage treatment plant project or the normal operation of the sewage treatment plant. At present, the conventional method uses manual observation, inquires one by one structural parts, and then conducts comprehensive treatment. For the entire plant area and multiple plant areas, on the one hand It is necessary to set up more maintenance personnel, the query efficiency of structural leakage and seepage is low, and there are certain safety risks for the leakage and seepage query of tall sewage treatment structures; on the other hand, for some hidden structural areas, Easy to ignore, difficult to control, and cause greater risk
