BIM-based track engineering construction progress information management method

Abstract

The invention discloses a BIM-based track engineering construction progress information management method. The method comprises the following steps: S1, establishing a three-dimensional simulation model of a to-be-constructed track construction based on BIM (Building Information Modeling); S2, establishing primitive information links for a construction progress plan and the three-dimensional simulation model in the S1, integrating time dimensions and forming a 4D progress visualization model; S3, applying the 4D progress visualization model to dynamic monitoring of the to-be-constructed trackconstruction, and comparing the actual construction progress and quality with the 4D progress visualization model to confirm consistency; if the actual construction progress and quality with the 4D progress visualization model are not consistent, carrying out S4: analyzing reasons of construction progress delays or poor quality; if the actual construction progress and quality with the 4D progressvisualization model are consistent, continuing S5: performing dynamic monitoring on each stage of the to-be-constructed track construction until the construction is completed. The method has the following advantages: the construction progress, related resources, the construction quality, site arrangement or the like can be comprehensively taken into consideration, plans can be formulated reasonably, resource utilization can be optimized, better dynamic monitoring and management of the whole construction progress can be realized, closed-loop feedback can be realized, and the efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of track engineering construction, in particular to a BIM-based management method for track engineering construction progress information. Background technique [0002] At present, the building information modeling (Building Information Modeling, BIM) technology is most used in the construction industry. BIM is based on various information data of construction projects as the basis of the model to establish the building model, and simulate the track through digital information simulation. The real information that the project has. It has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing.

Problems solved by technology

[0004] However, the above-mentioned patent establishes monitoring nodes at the construction site, and establishes acceptance criteria for the simulation model for the nodes, but it can only be inspected for a certain node in a certain construction stage in the construction site that can reflect the construction progress of the construction site. Only phased inspections can be carried out, but dynamic monitoring and management cannot be carried out, and real-time monitoring of the construction site cannot be carried out, which makes the construction process a potential safety hazard

In the technical solution disclosed in the above patent, the similarities and differences between the progress information represented by the nodes and the acceptance criteria can detect and deal with the problems in the construction stage in time, so as to adjust the simulation model or the on-site construction progress. The adjustment of the simulation model makes the simulation model established in advance for the nodes on the construction site change, resulting in a change in the acceptance criteria, which reduces the credibility of the construction process of the track engineering on the construction site, and makes use of the corresponding acceptance of the nodes to establish the progress of the simulation model. There is a large error in the standard
