in this embodiment, the construction model is created by a construction unit in real time during the construction process, and the construction information includes construction process attributes, material attributes, feed list information, quality inspector information, and the like.
The member refers to an independent unit constituting a main body of an engineering project, for example, in a bridge design and construction process, a single pier, a guy cable, a box girder, and the like can be regarded as a member, and a railway BIM system thereof can be called as a member model. During design and construction, component models of the same type and the same building specification have the same standard coding information, and independent components under each position and node have unique ID information. The component model library of the railway BIM system is used for recording information of all standard components applied in the railway construction process so as to form a unified standard, specifically, the component model records geometric information and non-geometric information, the geometric information comprises three-dimensional space information of the components, and the non-geometric information comprises material types, material specifications and/or construction process requirements of the components.
Step S20: creating a map model of a region where an entire railway project is located within a GIS system (Geographic information system technologies), the map model including Geographic location information and Geographic environment information;

Step S30: the method comprises the steps of inputting a map model into a railway BIM system, integrating a construction model and the map model into a comprehensive model in the railway BIM system, establishing an association relationship between positioning information of each component model of a railway project and geographic position information of the map model, and using the integrated comprehensive model for operation and maintenance of railway engineering.
In this embodiment, as shown in fig. 2, the construction model and the map model are integrated into a comprehensive model in the railway BIM system, or the construction model is entirely placed on the map model, and the coordinate systems of the construction model and the map model are associated with each other according to the actual geographical position relationship. The integrated comprehensive model can simultaneously carry construction information, geographical position, geographical environment information and the like of the construction model so as to be convenient for operation and maintenance of operation units.
The construction model established by the railway BIM system and the map model established in the GIS system are integrated into the comprehensive model, and the integrated comprehensive model can simultaneously carry the construction information, the geographic position, the geographic environment information and the like of the construction model so as to facilitate the operation and maintenance of an operation unit.

In the actual operation and maintenance stage, the railway BIM system can search the component model at the position based on the coordinate system, and all construction information contained in the component model is displayed at a user side of the railway BIM system. The coordinate system described here may be geographical position information of a map model, positioning information of a construction model, or a coordinate system reconstructed based on the geographical position information and the positioning information. Specifically, the method comprises the following steps:
a server of the railway BIM system receives a request of a user for viewing a specified road section, and opens the comprehensive model of the specified road section based on the geographical position information or the positioning information;
and the server checks the specified component model based on the ID information and displays the construction information carried by the component model at a user side of the railway BIM system.
In some embodiments, as shown in fig. 3 and 4, fig. 3 schematically illustrates the investigation mode after finding out the unqualified construction material of a certain place in the operation and maintenance process, and fig. 4 illustrates the investigation mode after finding out the unqualified construction process of a certain place in the operation and maintenance process.
As shown in fig. 3, specifically, the method includes the following steps:
step S41: the server associates the construction information of each component model of the construction model through the standard coding information of the component model;
step S42: and when the server receives a user request for displaying the material attribute, counting all component models of the same material according to the construction information and the standard coding information of each component, and displaying at the user side.
For example, in this embodiment, the operation and maintenance personnel find that the concrete of the bridge or the tunnel in a certain place is damaged, cracked, fallen off or deslagged. Opening a comprehensive model in the railway BIM system, and quickly searching a component model of a relevant position by relevant personnel through inputting a number, geographical position information or the positioning information or according to modes such as whole model navigation and the like; the server can then display all construction information carried by the component model at a user end of the railway BIM system. For example, information on what material a beam is, its material strength grade, its concrete grade, etc. is displayed. According to the actual research, the quality accident is caused by the unqualified material of the precast beam batch, and all the component models using the material can be counted according to the material properties and displayed at the user end. And then, the operation and maintenance personnel can detect the engineering components corresponding to the component models and take the detection result as a remedial measure for judging whether the engineering components need to be replaced, reinforced and the like.
In another embodiment, the constructor, the purchasing member, the supplier, the quality inspector, etc. may be responsible according to the feed list information and the quality inspector information of the construction information of the component model having the quality problem.
In one embodiment, as shown in fig. 4, the method specifically includes the following steps:
step S51: the server associates the construction information of each component model of the construction model through standard coding information of the component model;
step S52: and when the server receives a user request to display the construction process attribute, counting all component models of the same construction process according to the construction information and the standard coding information of each component, and displaying at the user side.
For example, in this embodiment, the operation and maintenance personnel find that the concrete of the bridge or the tunnel in a certain place is damaged, cracked, fallen off or deslagged. Opening a comprehensive model in the railway BIM system, and quickly finding out a component model of a relevant position by relevant personnel through inputting a number, geographical position information or the positioning information or according to the whole model navigation; the server can then display all construction information carried by the component model at a user end of the railway BIM system. For example, what construction process a certain pier/column/platform is shown. According to the actual research, the reason of the quality accident is the pile driving or pouring process of the pier/column/platform, and all the piers/columns/platforms using the construction process can be counted according to the material properties and displayed at the user end. And then, the operation and maintenance personnel can detect the engineering components corresponding to the component models and take the detection result as a remedial measure for judging whether the engineering components need to be replaced, reinforced and the like.
In another embodiment, the operator, the quality control staff, etc. may be followed up according to the quality control staff information of the construction information of the component model in which the quality problem occurs.
In the above embodiment, the manner of displaying at the user end is to highlight the corresponding component model. For example, the component models to be displayed are marked in red for display, and the unmarked component models are displayed in gray or green to distinguish the component models to be displayed.
In the above embodiment, the manner of displaying at the user side is to make the corresponding component model into a list, where the list includes a component name, positioning information, and ID information; the component name has a link to jump to a view showing the component model after clicking on the component name in order to view the component model.
In some embodiments, the geographic environmental information of the integrated model may include natural phenomena (e.g., hydrology, geomorphology, soil texture, vegetation) and social phenomena (e.g., residential areas, traffic lines, administrative boundaries, etc.) of the surrounding distribution environment. For example, the geographical environment information of the map model contains route information to visually display a route of a railroad project that can reach a designated area in the integrated model for planning a rescue route.
For example, when natural disasters such as landslide and debris flow occur on a railway line in some mountain environments in the south, the natural disaster section can be checked in the comprehensive model, and meanwhile, reachable traffic modes of the natural disaster section can be visually displayed, and rescue or maintenance personnel adopt traffic modes such as an engineering truck, an off-road vehicle, a waterway, a helicopter, walking and the like according to actual needs.
