Problems solved by technology

Due to the limitation of BIM modeling ability and the shortage of BIM technology application, the application of BIM traffic guidance settings is limited. Therefore, it is necessary to design a new type of BIM technology-based traffic guidance method in municipal engineering.

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the examples.

[0018] Preliminary review shall be carried out on the design description, structural construction drawings, pipeline diagrams of surrounding buildings (structures), construction plans, and professional deepening drawings in the construction drawings issued by the design unit. Sort and summarize the drawing problems that arise to the design unit, adjust and modify the construction drawings, specifically including the construction layout, size and elevation, scope, node layout, etc.

[0019] Before modeling, collect relevant data on modeling standards and coding. According to the BIM modeling specification and the actual project situation, a BIM modeling standard in line with road engineering is established to standardize the 3D model; the BIM coding system is based on the BIM data model, and the BIM model is used as the coding carrier, that is, all codes can correspond to ...

Abstract

The invention relates to a BIM technology-based municipal engineering traffic dispersion method, which comprises the following steps: checking, conforming to a design drawing, and carrying out preliminary review on the design drawing; establishing a three-dimensional model through Revit modeling software according to the corrected design drawing and the BIM modeling standard, and outputting a model file in an FBX format; encoding and splitting the model according to the progress plan and the construction process to ensure that the BIM model is matched with the construction progress; obtainingtraffic flow information and morning and evening peak time periods through data provided by a traffic management department and aerial photography of the unmanned aerial vehicle; and importing the FBXfile into LumenRT software for traffic simulation, determining a reasonable dispersion scheme, and optimizing the traffic dispersion scheme. Traffic in a construction influence range is simulated byusing a three-dimensional dynamic model, a traffic defibering scheme is optimized for input of related data such as traffic flow in different time periods, and traffic enclosures, indication boards, warning signs and the like are reasonably arranged.

Description

technical field [0001] The invention relates to the technical field of municipal engineering construction, in particular to a method for dredging municipal engineering traffic based on BIM technology. Background technique [0002] With the acceleration of my country's urbanization process, the original municipal roads cannot meet the growing traffic volume, and the number of municipal road projects is also increasing. Traffic guidance is very important for municipal engineering, and it is also an important task in the construction preparation stage. The traditional traffic guidance method uses the general construction plan to set up, and uses CAD drawings to perform two-dimensional traffic simulation. [0003] With the promotion and application of BIM technology, the method of simulating traffic flow scheme based on BIM three-dimensional modeling has attracted more and more attention. Due to the limitation of BIM modeling ability and the shortage of BIM technology applicat...
