Temporary building model establishing method based on three-dimensional GIS and BIM integration, and application thereof

Abstract

The invention discloses a temporary building model establishing method based on three-dimensional GIS and BIM integration. The method comprises the following steps: establishing a BIM model; collecting three-dimensional GIS information; converting the three-dimensional GIS information by adopting a classification conversion method, and importing the three-dimensional GIS information into a BIM platform; integrating BIM model data and the converted three-dimensional GIS information, and establishing a three-dimensional integrated temporary building model on the basis of the BIM model data and the converted three-dimensional GIS information; using a BIM5D platform, importing various construction information into the BIM5D platform, simulating a construction process in combination with the three-dimensional integrated temporary building model, and establishing a 5D temporary building model based on the construction progress and a construction cost. According to the invention, three-dimensional GIS information is converted and then integrated with a BIM model, a three-dimensional integrated temporary building model based on the BIM platform is obtained, a construction process is subjected to 5D simulation in combination with construction information, and a construction scheme is dynamically adjusted according to a simulation result, so that the management capability of long-line and large-scale regional engineering is improved.

Description

technical field [0001] The present invention relates to fields. More specifically, the present invention relates to a temporary construction model establishment method and application based on the integration of 3D GIS and BIM. Background technique [0002] BIM technology has been widely used in existing engineering construction. With the continuous development of national infrastructure level, new requirements are put forward for construction efficiency and process quality control. In large-scale building construction, there are often problems such as complex construction sites, long construction lines, inconvenient RTK data collection, and difficult re-survey of design lines. Especially when there are a large number of temporary construction facilities in the construction site, due to the limited construction space available, Simply relying on the existing construction drawings and construction experience will easily lead to problems such as unreasonable temporary constru...

AI Technical Summary

Problems solved by technology

In large-scale building construction, there are often problems such as complex construction sites, long construction lines, inconvenient RTK data collection, and difficult re-survey of design lines. Especially when there are a large number of temporary construction facilities in the construction site, due to the limited construction space available, Simply relying on the existing construction drawings and construction experience will easily lead to problems such as unreasonable temporary construction scheme design, increase the construction difficulty of the main project, affect the construction progress and construction quality of the main project, and greatly increase the construction cost

However, the application object of BIM technology is often a single building, and it cannot be used to simulate temporary construction projects and optimize temporary construction schemes under the complex surrounding environment of the project.
