The 3D construction model is a unit integral model of a construction site, and comprises but is not limited to a pilot tunnel excavation construction model, an advanced small conduit construction model and a steel grating installation construction model, and then a simulation 4D animation simulation construction process is generated through a Revit modeling platform so as to correct the accuracy of model information, correct incorrect model data and correspondingly modify a design drawing. And the data of the 3D construction model is maintained and updated regularly. Meanwhile, according to the comparison between the signed planned construction progress model and the actual construction progress model, the difference between the actual construction progress and the expected planned construction progress can be obtained, and therefore the actual construction plan can be adjusted in time according to actual conditions.
Examples
Firstly, a Revit modeling platform is utilized to perform modeling according to a design drawing of a project, including but not limited to advanced small guide pipes, steel grids, locking anchor rods and sprayed concrete modeling in a pilot tunnel, if input parameters are not accordant with or conflict with actual construction, a highlight display is performed in a drawn three-dimensional BIM model, namely a 3D construction model, and an error is prompted, so that the design drawing and construction parameters are effectively rechecked, and the error in the design drawing is found in advance before the actual construction, and the purpose of auditing the design drawing is achieved.
