Description

Technical Field

[0001] This invention relates to the field of nuclear power plant site layout technology, and in particular to a method and system for nuclear power plant site layout based on SketchUp software. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Currently, no design institute in the nuclear power industry has a complete BIM-based forward design solution for site layout design. Some design institutes have tried to use software such as Civil 3D and Revit for site layout construction drawing design. However, due to limitations in the coordination of 3D model data from different disciplines and the limitations of the software platforms themselves, they cannot meet the requirements of the existing construction drawing output system. There is currently no digital 3D design software specifically customized for the site layout profession. All kinds of software can only partially support the 3D design of the nuclear power plant site layout. There is an urgent need to invent a working method to realize the 3D visualization design of the nuclear power plant site layout for the site layout profession.

[0004] Patent CN 104631826 A proposes a working method based on BIM technology for the overall site layout of a construction site. However, the overall site layout of a construction site differs from the overall site layout of a nuclear power plant in terms of working objects and principles. Therefore, the working method of this patent is not applicable to the overall site layout of a nuclear power plant, both in terms of applicable objects and workflow.

[0005] Patent CN 113642066 A proposes a site layout method based on Revit software. It mainly targets the modeling process and work steps of outdoor works such as red lines, roads, and walls in small-scale civil and industrial construction projects. It is suitable for small-scale civil projects, but it cannot be applied to the complex modeling objects of large nuclear power plants, such as various outdoor terrains and geological features. Therefore, this patent is not suitable for large nuclear power plant areas in terms of scale or the types of layout objects. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a method and system for the overall layout of nuclear power plant sites based on SketchUp software, which can intuitively express and spatially visualize the overall layout scheme of nuclear power plants in a three-dimensional space.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] A method for the overall layout of a nuclear power plant site based on SketchUp software includes the following steps:

[0009] Based on the scale and model of the nuclear power plant, collect two-dimensional drawings of the outdoor buildings and facilities in the plant area, and build a three-dimensional model based on the two-dimensional drawings;

[0010] Based on past experience data, auxiliary buildings and facilities are planned and arranged with the nuclear island plant and conventional island plant as the center, and the initial planning and layout of the plant area is completed.

[0011] Specifically, first, a construction coordinate system for the plant area itself is established; then, the existing three-dimensional models of the outdoor buildings and facilities in the plant area are planned and arranged around the nuclear island plant; finally, the three-dimensional models of the auxiliary buildings and facilities are improved and formed into self-contained components.

[0012] Based on the site survey data, an original digital elevation model of the area where the plant is located was established.

[0013] Based on the site exploration data and combined with the excavation depth of the nuclear island plant, a three-dimensional model of geological elements was established.

[0014] Based on the original topography and the spatial distribution of the underground bedrock, the spatial geographical location of the three-dimensional model of the main nuclear island building is first solidified, and then the original ground digital elevation model and the three-dimensional model of geological related elements are integrated based on the same construction coordinate system.

[0015] Based on factors such as the overall site plan, site leveling, earthwork balance, layout of slope retaining wall facilities, flood control and drainage, and the stability of the bedrock of the nuclear island plant, the overall spatial layout of the plant area was repeatedly analyzed and finalized.

[0016] Furthermore, when creating a three-dimensional model from two-dimensional drawings, the basic idea of ​​modeling is to combine the plan, elevation, and section drawings of the facility, start with the plan view, recreate the elevation drawings in the corresponding spatial positions, and finally create a three-dimensional model.

[0017] Furthermore, the auxiliary building structures include roads, plazas, gravel paving, and green landscaping.

[0018] Furthermore, when establishing the factory's own construction coordinate system, the vertical part of the site follows the order of first laying out the plan and then setting the vertical elevation to complete the vertical space modeling within the factory area.

[0019] Furthermore, when establishing the original ground digital elevation model of the area where the factory is located, the coordinate system of the site survey data is first converted into the existing construction coordinate system according to the actual situation. Then, contour lines and elevation points are used to establish a triangulation digital model of the ground surface. The model is then imported into SketchUp software to cover all the triangulations and soften the edges of the triangulations to obtain the original ground digital elevation model of a certain range around the factory area. At the same time, various ground feature information is projected onto the original ground digital elevation model in the form of lines.

[0020] Furthermore, when establishing three-dimensional models of geologically related elements, under the same construction coordinate system, based on the exploration borehole data of the plant area and cross-sectional views of different elevation layers, the CAD graphics are processed and imported into SketchUp software, with a focus on establishing three-dimensional models of strongly, moderately, and weakly weathered bedrock areas.

[0021] Furthermore, when establishing a three-dimensional model of geological elements, the layout map of the exploration boreholes in the plant area is imported into SketchUp software under the same construction coordinate system. The underground part of each borehole is divided into components according to different rock strata, and the materials of each component are distinguished to form a borehole column. Then, the boundary points of the same rock strata of different boreholes on the borehole column are connected with lines to form a cover, forming a bedrock surface. Each bedrock surface is a component and named according to the actual situation. Finally, the spatial position and content of each bedrock surface are checked against the cross-sectional view.

[0022] Furthermore, when creating a three-dimensional model from two-dimensional drawings, the individual models of buildings become self-contained components, serving as the basic building blocks for the large-scale model of the factory area.

[0023] Furthermore, when planning and arranging auxiliary buildings and facilities, the requirements of nuclear power plant production processes and fire protection should be taken into account.

[0024] A nuclear power plant site layout system based on SketchUp software, comprising:

[0025] The initial 3D model building module is used to collect 2D drawings of professional outdoor buildings and facilities in the nuclear power plant area based on the scale and model of the nuclear power plant, and to build a 3D model from the 2D drawings.

[0026] The preliminary layout module for plant planning is used to plan and arrange auxiliary buildings and facilities based on past experience data, with the nuclear island plant and conventional island plant as the center, and to initially complete the plant planning and layout. Specifically, first, the construction coordinate system of the plant itself is established, then the existing three-dimensional models of the plant's outdoor buildings and facilities are planned and arranged around the nuclear island plant, and finally the three-dimensional models of the auxiliary buildings and facilities are improved and formed into a self-contained component.

[0027] The original ground digital elevation model creation module is used to create an original ground digital elevation model of the area where the plant is located based on the site survey data.

[0028] The 3D model building module for geologically related elements is used to build 3D models of geologically related elements based on site exploration data and the excavation depth of the nuclear island building.

[0029] The integration module is used to integrate the original ground digital elevation model and the three-dimensional model of geological elements based on the spatial geographical location of the first solidified three-dimensional model of the main nuclear island building, according to the original topography and the spatial distribution of the underground bedrock.

[0030] The overall spatial layout of the plant area is solidified by repeatedly analyzing factors such as the overall site plan, site leveling, earthwork balance, slope and retaining wall layout, flood control and drainage, and the stability of the bedrock of the nuclear island plant.

[0031] The beneficial effects of the present invention are as follows:

[0032] 1) Based on the same construction coordinate system, this invention integrates the three-dimensional model of the geological bedrock, the original three-dimensional digital model of the ground surface, and the three-dimensional model of the buildings and structures within the plant area. It can make a three-dimensional visual and intuitive judgment on the stability of the nuclear island plant in the underground three-dimensional space environment, ensuring the rationality and safety of the nuclear power plant technical solution. It can also make an intuitive observation and experience of the landscape and features of the plant area in the above-ground three-dimensional space environment, improving the aesthetics, rationality and feasibility of the plant area's planning and layout.

[0033] 2) The SketchUp software of this invention can easily and freely create three-dimensional models of all items in the factory area, including buildings, outdoor equipment and their foundations, terrain features, underground geology and other elements. It can achieve the goal of creating a model covering all outdoor engineering related items in the factory area on one software platform, and meet the needs of the general layout profession for impact analysis and collision detection of all items.

[0034] 3) The SketchUp software of this invention has a good interface and can be connected to different software platforms and different types of models at any time as other professional design models are developed. It supports the integration of data in different formats and meets the needs of general layout professionals for summarizing multi-source heterogeneous data. Attached Figure Description

[0036] Figure 1 This is a flowchart of a method for the overall layout of a nuclear power plant site based on SketchUp software, according to one or more embodiments of the present invention. Detailed Implementation

[0037] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0038] Example 1

[0039] A method for overall site layout of a nuclear power plant based on SketchUp software, such as... Figure 1 As shown, it includes the following steps:

[0040] Step 1: Based on the nuclear power plant's construction scale, turbine type, and other conditions, collect 2D drawings of outdoor buildings, structures, equipment, and other facilities within the plant area, specializing in architecture, structure, and equipment. Then, create a 3D model from these drawings. The basic modeling approach is to combine the facility's plan, elevation, and section drawings, starting with the plan view and recreating the elevation drawings at corresponding locations in space to ultimately build a 3D model. The interior of buildings is not modeled; individual models of buildings / equipment form self-contained components, serving as the basic building blocks for the larger-scale plant model.

[0041] Step 2: Based on past experience data and in conjunction with the nuclear power plant's production process and fire protection requirements, other auxiliary buildings and facilities are planned and arranged around the nuclear island and conventional island buildings, thus completing the initial planning and layout of the plant area.

[0042] First, establish the plant's own construction coordinate system. Then, plan and arrange the existing individual or outdoor equipment and other facilities around the nuclear island plant. Finally, improve the three-dimensional models of roads, squares, gravel paving, green landscapes and other facilities, and make them into components. The vertical part of the site follows the order of first laying out the plan and then setting the vertical elevation to complete the vertical space modeling within the plant area.

[0043] Step 3: Based on the site survey data, establish the original digital elevation model of the area where the factory is located;

[0044] Based on the actual situation, the coordinate system of the site survey data is converted into the existing construction coordinate system. Then, contour lines and elevation points are used to create a triangulation digital model of the ground surface using professional software. The model is then imported into SketchUp software to cover all the triangulation networks and soften the edges of the triangulation networks to obtain the original ground digital elevation model (DEM) of a certain area around the factory area. At the same time, various ground feature information is projected onto the original ground digital elevation model in the form of lines.

[0045] Step 4: Based on the site exploration data and combined with the excavation depth of the nuclear island plant, establish a three-dimensional model of the geological elements.

[0046] Under the same construction coordinate system, the layout map of the exploration boreholes in the plant area is imported into SketchUp software. The underground part of each borehole is divided into components according to different rock strata, and the materials of each component are distinguished to form a borehole column. Then, the boundary points of the same rock strata of different boreholes on the borehole column are connected with lines to form a cover, forming a bedrock surface. Each bedrock surface is a component and named according to the actual situation. Finally, the spatial position and content of each bedrock surface are checked against the cross-sectional view.

[0047] Step 5: Based on the same construction coordinate system and according to the original topography and the spatial distribution of the underground bedrock, first solidify the spatial geographical location of the three-dimensional model of the main nuclear island building, and then integrate the models of other buildings and structures, that is, summarize the results of Step 2, Step 3 and Step 4 into a core model.

[0048] Step Six: Based on factors such as the overall site plan, site leveling, earthwork balance, slope retaining wall layout, flood control and drainage, and the stability of the bedrock of the nuclear island plant, conduct repeated iterative analysis to solidify the overall spatial layout model of the plant area.

[0049] Specifically, in step five, the integration of the three-dimensional geological bedrock model, the original three-dimensional digital model of the ground surface, and the model of the main nuclear island building within the plant area, based on the same construction coordinate system, enables a three-dimensional visualization and intuitive judgment of the stability of the nuclear island building in the underground three-dimensional space environment, ensuring the rationality and safety of the nuclear power plant technical solution.

[0050] Specifically, in step five, the integration of the three-dimensional geological bedrock model, the original three-dimensional digital model of the ground surface, and the building models of the main nuclear island within the plant area, based on the same construction coordinate system, allows for intuitive observation and experience of the plant's landscape and features in a three-dimensional spatial environment on the ground, thereby enhancing the aesthetics, rationality, and feasibility of the plant's planning and layout.

Specifically, first, the construction coordinate system of the plant itself is established, then the existing three-dimensional models of the plant's outdoor buildings and facilities are planned and arranged around the nuclear island plant, and finally the three-dimensional models of the auxiliary buildings and facilities are improved and formed into a self-contained component.
