Description

Technical Field

[0002] With the vigorous development of my country's infrastructure, bridge engineering is also developing towards dangerous mountainous areas and deep-sea scenarios; and the temporary construction planning scenarios in the early stages of bridge construction directly determine the transportation efficiency and convenience of the entire bridge construction process.

[0003] Temporary buildings refer to temporary buildings, structures and other temporary facilities for living and production that construction companies must set up to carry out engineering construction. They mainly include temporary living buildings (project sites), temporary production buildings (concrete mixing plants, steel bar processing centers) and temporary construction buildings (piers, construction platforms), etc. Bridge projects have a long construction time, large project volume and complex construction environment, so the number of various types of temporary buildings is far greater than that of other types of projects. In particular, for bridges built in dangerous mountainous areas, temporary construction planning needs to be carried out in the early stages of the project based on the topography, road conditions and geological conditions of the project area.

[0004] At present, the traditional temporary construction site selection is mainly planned by manual survey, and then the drawings are designed; the design of each temporary construction is relatively independent, mainly considering the floor area and production efficiency of a single temporary construction, and it is difficult to consider the planning of temporary construction groups in an all-round way; especially for the planning of bridge construction in dangerous mountainous areas, due to complex geological conditions, lack of flat land, large height differences in the construction area and other problems, if the temporary construction cannot be planned as a whole, it will lead to excessive dispersion of temporary construction, low transportation efficiency and the design of large-scale temporary road construction, thus affecting the construction efficiency of the entire project; it is difficult to estimate the excavation and filling and temporary road construction projects involved in the construction of temporary construction through traditional planning methods, and basically the construction is calculated step by step, which is difficult to fully control.

The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001.

[0054] Those skilled in the art will understand that Figure 1 The device structure shown in the figure does not constitute a limitation of the device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0056] The device of the present invention calls the bridge engineering forward planning program stored in the memory 1005 through the processor 1001 and performs the operations in the embodiment of the bridge engineering forward planning method described below.

[0057] Through the above scheme, this embodiment obtains a temporary construction BIM model by performing BIM modeling and model deepening on the temporary construction planning scene of the bridge project; obtains a three-dimensional real-scene model and a geological model of the construction area, and fuses the temporary construction BIM model, the three-dimensional real-scene model and the geological model with multi-source data based on the GIS engine to obtain a fusion model; visualizes the fusion model based on the B / S architecture, and can perform related work anytime and anywhere, which greatly improves the convenience of planning and design, and achieves a comprehensive view of the overall situation while focusing on the details of each temporary construction. The size, dimensions, layout and other attributes of the temporary construction can be quickly and conveniently modified to make it more in line with the terrain characteristics and usage requirements, and the geological conditions can be considered in the design stage. The temporary construction model and the geology can be combined for finite element analysis, which can ensure the design safety of temporary construction.

[0058] Based on the above hardware structure, an embodiment of the bridge engineering forward planning method of the present invention is proposed.

[0059] Reference Figure 2 , Figure 2 2 is a flow chart of the first embodiment of the forward planning method for bridge engineering according to the present invention.

[0060] In a first embodiment, the bridge engineering forward planning method includes the following steps:

[0061] Step S10: Perform BIM modeling and model deepening on the temporary construction planning scenario of the bridge project to obtain a temporary construction BIM model.

[0062] It should be noted that the temporary construction planning scenario for bridge engineering is a forward design planning for temporary construction buildings for bridge engineering. By performing Building Information Modeling (BIM) modeling and model deepening on the temporary construction planning scenario for bridge engineering, a temporary construction BIM model can be obtained. The temporary construction BIM model can reflect the temporary construction area, site planning and functional design.

[0063] In specific implementation, temporary buildings refer to temporary buildings, structures and other temporary facilities for living and production that must be set up by construction companies to carry out engineering construction; they mainly include temporary living buildings (project sites), temporary production buildings (concrete mixing plants, steel bar processing centers) and temporary construction buildings (piers, construction platforms), etc. This embodiment does not impose any restrictions on this.

[0064] Step S20: Acquire a three-dimensional real scene model and a geological model of the construction area, and fuse the temporary construction BIM model, the three-dimensional real scene model, and the geological model based on a GIS engine to obtain a fusion model.

[0065] It can be understood that by obtaining a three-dimensional real-scene model and a geological model of the construction area, the three-dimensional real-scene model can restore the terrain, roads, vegetation and buildings of the entire construction scene, and based on the GIS engine, the temporary construction BIM model, the three-dimensional real-scene model and the geological model are multi-source data fused to obtain a fusion model of multi-source data such as BIM and 3Dtails, thereby realizing the visualization of temporary construction planning scenes.

[0066] Step S30: Visualize and interact with the fusion model based on the B / S architecture.

[0067] It should be understood that the fusion model can realize visual interaction based on the B / S architecture, that is, the appearance and layout of the temporary building can be viewed in a visual way, and the application requirements of the virtual construction interactive scene can be met.

[0068] Through the above scheme, this embodiment obtains a temporary construction BIM model by performing BIM modeling and model deepening on the temporary construction planning scene of the bridge project; obtains a three-dimensional real-scene model and a geological model of the construction area, and fuses the temporary construction BIM model, the three-dimensional real-scene model and the geological model with multi-source data based on the GIS engine to obtain a fusion model; visualizes the fusion model based on the B / S architecture, and can perform related work anytime and anywhere, which greatly improves the convenience of planning and design, and achieves a comprehensive view of the overall situation while focusing on the details of each temporary construction. The size, dimensions, layout and other attributes of the temporary construction can be quickly and conveniently modified to make it more in line with the terrain characteristics and usage requirements, and the geological conditions can be considered in the design stage. The temporary construction model and the geology can be combined for finite element analysis, which can ensure the design safety of temporary construction.

[0069] Furthermore, Figure 3 This is a flow chart of the second embodiment of the bridge engineering forward planning method of the present invention. Figure 3 As shown, a second embodiment of the bridge engineering forward planning method of the present invention is proposed based on the first embodiment. In this embodiment, step S10 specifically includes the following steps:

[0070] Step S11: perform BIM modeling and model deepening on the temporary construction planning scenario of the bridge project to obtain a target model after deepening.

[0071] It should be noted that by performing BIM modeling and model deepening on the temporary construction planning scenario of the bridge project, the model after deepening can be obtained as the target model.

[0072] Furthermore, the step S11 includes the following steps:

[0073] Conduct BIM modeling of temporary construction planning scenarios for bridge projects to obtain planning scenario BIM models;

[0074] The temporary construction functional zoning of the planning scenario BIM model is displayed in three dimensions and the model is deepened to obtain the target model after the deepening is completed.

[0075] It can be understood that by carrying out BIM modeling of the temporary construction planning scenario of the bridge project, a BIM model of the planning scenario can be obtained, and by planning the temporary construction functional zoning through three-dimensional display, the target model after in-depth completion can be obtained.

[0076] Step S12: Obtain the scene and environmental requirements corresponding to the target model, adjust the model size, model position and model quantity of the temporary building structure according to the scene and environmental requirements, and obtain a temporary building BIM model.

[0077] It can be understood that after obtaining the scene and environmental requirements corresponding to the target model, the deepened model can adjust the size, position and number of the structure models in the temporary building according to the scene and environmental requirements of the model, so as to realize the landscape planning and functional design of the temporary building.

[0078] It should be understood that after obtaining the BIM model of the temporary building, the appearance and layout of the temporary building can be viewed through model visualization, and the functional divisions and planning inside the model can be intuitively viewed through the roaming function;.

[0079] In specific implementation, for temporary building models during the construction process, the BIM model can be used to realize the statistics and mechanical properties simulation of construction materials. By establishing a high-precision BIM model, the engineering quantity of steel pipe piles and Bailey frames can be quickly counted, and the model can be connected to the finite element analysis software for mechanical analysis to ensure the rationality of the design. Compared with other types of models, the BIM model has a high degree of parameterization. The temporary building design needs to be repeatedly optimized and modified according to the actual terrain characteristics and address conditions. Therefore, the BIM model can be used to modify the model by modifying the parameters.

[0080] Through the above scheme, this embodiment obtains the target model after the deepening by performing BIM modeling and model deepening on the temporary construction planning scenario of the bridge project; obtains the scene and environmental requirements corresponding to the target model, adjusts the model size, model position and model quantity of the structures in the temporary construction according to the scene and the environmental requirements, and obtains the temporary construction BIM model, which can realize rapid modification of the model and meet the needs of rapid optimization of the model.

[0081] Furthermore, Figure 4 This is a flow chart of the third embodiment of the bridge engineering forward planning method of the present invention. Figure 4 As shown, a third embodiment of the bridge engineering forward planning method of the present invention is proposed based on the first embodiment. In this embodiment, step S20 specifically includes the following steps:

[0082] Step S21: Use a drone to perform equidistant tilt aerial survey of the ground in the construction area at a constant speed, and collect image information from different shooting angles and drone POS data through multiple aerial surveys.

[0083] It should be noted that the three-dimensional real-scene model requires the use of a drone to conduct equidistant tilt aerial surveys of the construction site ground at a constant speed, and through multiple aerial surveys, image information from different shooting angles and corresponding POS data are collected as materials for building the model.

[0084] It is understandable that when a drone is in flight, the drone images obtained usually carry supporting POS data, namely the exterior orientation elements in oblique photogrammetry: (heading angle phi, pitch angle omega and roll angle kappa), and of course can also include latitude, longitude and elevation data, which is not limited in this embodiment; thereby, the images can be processed more conveniently during processing.

[0085] Step S22: perform computational processing on the image information and the drone POS data to obtain a three-dimensional model of the photographed object.

[0086] It can be understood that by performing computational processing on the image information and the drone POS data, a three-dimensional model of the object being photographed can be obtained. The image information and the drone POS data can be used as corresponding photo data. By performing computational processing on the photo data, a three-dimensional model of the object being photographed can be formed by fitting photos taken at different shooting angles.

[0087] Step S23: Deepen the design of the three-dimensional model of the photographed object to obtain a three-dimensional real scene model.

[0088] It should be understood that the three-dimensional model of the photographed object is further designed to obtain a three-dimensional real scene model, for example, a three-dimensional real scene model of the area is formed after flattening the areas on both sides of the road, repairing the water surface, filtering floating objects, etc.

[0089] In the specific implementation, the three-dimensional real-life terrain model is used to achieve precise positioning of temporary buildings and carry out distributed temporary construction planning scenarios. The three-dimensional real-life model contains a geodetic coordinate system. By inputting coordinates, the temporary building BIM model is placed on the corresponding coordinate points of the three-dimensional real-life terrain model. The model placement process can match the terrain in the three spatial dimensions of X, Y, and Z, and the model can be rotated, translated, flipped, and fine-tuned with the mouse.

[0090] Step S24: Acquire a geological cross-section map and survey data of the construction area, and construct a geological model based on the geological cross-section map and the survey data.

[0091] It is understandable that an address model can be established based on geological cross-section maps and survey data. The establishment of a geological model can guide the site selection of temporary construction structures and ensure construction safety. The geological model is essentially a BIM model, which can be processed through BIM software and can also be combined with a three-dimensional real-scene model.

[0092] In the specific implementation, in order to meet the project's precise positioning needs, the three-dimensional real-scene model captured and processed by the drone can be connected to the digital elevation model according to the longitude and latitude, so as to greatly improve the accuracy of the geographic model of the construction area. The accuracy can be increased from 5m to 5cm. After the high-precision geographic information model is deployed, the BIM model can be positioned and placed on the platform.

[0093] Step S25: Based on the GIS engine, the temporary construction BIM model, the three-dimensional real scene model and the geological model are subjected to multi-source data fusion to obtain a fusion model.

[0094] It should be understood that, based on the GIS engine, the temporary construction BIM model, the three-dimensional real scene model and the geological model can be fused through multi-source data to obtain a fusion model.

[0095] Through the above scheme, this embodiment uses a drone to conduct equidistant oblique aerial surveys of the ground in the construction area at a constant speed, and collects image information and drone POS data at different shooting angles through multiple aerial surveys; the image information and the drone POS data are processed to obtain a three-dimensional model of the object being photographed; the three-dimensional model of the object being photographed is further designed to obtain a three-dimensional real-scene model; the geological cross-section map and survey data of the construction area are obtained, and a geological model is constructed based on the geological cross-section map and the survey data; based on the GIS engine, the temporary building BIM model, the three-dimensional real-scene model and the geological model are multi-sourced and fused to obtain a fusion model, which can better meet the terrain characteristics and usage requirements, can consider the geological conditions in the design stage, and can combine the temporary building model with the geology for finite element analysis, so as to ensure the design safety of temporary construction.

[0096] Furthermore, Figure 5 This is a flow chart of the fourth embodiment of the bridge engineering forward planning method of the present invention. Figure 5 As shown, a fourth embodiment of the bridge engineering forward planning method of the present invention is proposed based on the third embodiment. In this embodiment, step S25 specifically includes the following steps:

[0097] Step S251: Acquire the geographic coordinates of the GIS engine, and connect the latitude and longitude coordinates of the three-dimensional real scene model to the geographic coordinates.

[0098] It should be noted that after obtaining the 3D real scene model, the 3D real scene model can be connected to the geographic coordinates of the virtual construction platform Geographic Information System (GIS) engine through longitude and latitude coordinates to complete the layout of the real scene terrain in the engine.

[0099] It should be understood that GIS is a system used in the surveying and mapping industry, and GIS engines are often used in navigation and other systems; because this system can not only integrate geographic information, but also present BIM models through the GIS engine by format conversion using the Inline Formatting Contexts (IFC) format.

[0100] Step S252: Process the temporary construction BIM model and the geological model through BIM software, and perform multi-source data fusion of the processed temporary construction BIM model and the geological model with the three-dimensional real scene model to obtain a fusion model.

[0101] It can be understood that the temporary construction BIM model and the geological model are processed by BIM software, and the processed temporary construction BIM model and the geological model are fused with the three-dimensional real scene model through multi-source data to obtain a fusion model.

[0102] In the specific implementation, in order to better form a complete program with the help of a carrier for BIM models and three-dimensional real-scene models, a graphics engine is needed to integrate the model and develop interactive functions; through a comprehensive analysis of the development cost, operating efficiency, and presentation form of various graphics engines such as UE4, Unity 3D, and GIS, it was decided to use a GIS engine with high open source and good integration with three-dimensional real-scene models as the carrier.

[0103] This embodiment adopts the above scheme, obtains the geographic coordinates of the GIS engine, and connects the latitude and longitude coordinates of the three-dimensional real scene model to the geographic coordinates; processes the temporary construction BIM model and the geological model through BIM software, and performs multi-source data fusion of the processed temporary construction BIM model and the geological model with the three-dimensional real scene model to obtain a fusion model; it can better meet the terrain characteristics and usage requirements, can consider the geological conditions in the design stage, and can combine the temporary construction model and the geology to perform finite element analysis, which can ensure the design safety of temporary construction.

[0104] Furthermore, Figure 6 FIG. 5 is a flow chart of the fifth embodiment of the bridge engineering forward planning method of the present invention. Figure 6 As shown, a fifth embodiment of the bridge engineering forward planning method of the present invention is proposed based on the first embodiment. In this embodiment, step S30 specifically includes the following steps:

[0105] Step S31: Publish the fusion model to the web page based on the B / S architecture, and develop corresponding interactive functions according to actual needs.

[0106] It should be noted that by publishing the fusion model integrated with the three-dimensional real-scene model to the web page, different interactive functions can be developed according to actual needs.

[0107] It is understandable that GIS engines are widely used in the surveying and mapping industry. They can integrate geographic information, support B / S architecture, and convert BIM models into IFC, 3Dtails and other formats for integration. At the same time, GIS engines can read data and refresh models in real time, and display vehicle locations and monitoring data in real time on the web page. Compared with other more closed C / S engines, they can meet the needs of virtual construction.

[0108] Step S32: running the interactive function on the web page to realize visual interaction.

[0109] It can be understood that running the interactive function on the web page can realize the visual interaction of the forward planning of temporary construction of bridge projects. The use of GIS combined with BIM to achieve visualization can change the problem that traditional planning is not intuitive and it is difficult to consider the overall situation of the entire construction area only through two-dimensional drawings and contour maps.

[0110] In the specific implementation, the Ceisum engine, as an open source GIS engine, is not a customized product. It supports JavaScript development and B / S (web page) packaging. It can be customized according to actual needs to meet the application requirements of virtual construction interactive scenes. It can integrate BIM models, three-dimensional real-scene models and geological models on the web page for operation, and can perform related work anytime and anywhere, which greatly improves the convenience of planning and design; it greatly improves the degree of interaction in planning. On the WEB side, the program only needs to use the mouse to arrange temporary buildings according to needs, so as to achieve a comprehensive view and focus on the details of each temporary building. The parameterized characteristics of the model reduce the cost of modifying the plan. By modifying the parameters, the size, dimensions, layout and other attributes of the temporary building can be quickly and conveniently modified to make it more in line with the terrain characteristics and usage needs. By combining geology and topography, the geological conditions can be considered in the design stage, and the temporary building model and geology can be combined for finite element analysis to ensure the design safety of temporary buildings under construction.

[0111] This embodiment uses the above solution to publish the fusion model to the web page based on the B / S architecture, and develop corresponding interactive functions according to actual needs; running the interactive functions on the web page to realize visual interaction can greatly improve the convenience of planning and design, achieve a comprehensive view of the overall situation and focus on every detail of the temporary construction, and ensure the design safety of temporary construction.

[0112] Furthermore, Figure 7 This is a flow chart of the sixth embodiment of the bridge engineering forward planning method of the present invention. Figure 7As shown, a sixth embodiment of the bridge engineering forward planning method of the present invention is proposed based on the fifth embodiment. In this embodiment, step S31 specifically includes the following steps:

[0113] Step S311: Publish the fusion model to the web page based on the B / S architecture.

[0114] It should be noted that the fusion model is published to the web page based on the B / S architecture, so that by developing corresponding functions, the forward design planning of temporary construction can be realized through the web page.

[0115] Step S312: Develop a temporary terrain matching and road planning interactive function based on transportation needs to calculate road distances according to planned position relationships.

[0116] It can be understood that according to transportation needs, temporary building terrain matching and road planning interactive functions are developed to calculate road distances based on planned position relationships, matching of temporary living buildings and terrain, and road planning between temporary buildings. Position relationships can be planned according to the functional characteristics and transportation needs of each temporary building. By clicking on any two models in the platform, the road distance can be automatically displayed and calculated, which can optimize the layout of temporary buildings.

[0117] Step S313: Develop a temporary construction overall layout effect evaluation function for adjusting temporary construction facilities based on the overall layout effect of the temporary construction according to the temporary construction layout requirements.

[0118] It should be understood that, according to the needs of temporary construction layout, a temporary construction overall layout effect evaluation function is developed, which can adjust the temporary construction facilities according to the overall layout effect of the temporary construction. Based on the WEB side, the overall layout effect of the temporary construction is evaluated through functions such as rotating terrain and roaming. It can very intuitively present the temporary construction layout of the entire project, and timely adjust the unreasonable layout of temporary facilities to ensure that the temporary construction layout in complex mountainous environments is adapted to local conditions.

[0119] Step S314: Develop a single temporary construction site planning function based on the temporary construction functional design requirements.

[0120] It is understandable that the planning function of a single temporary building site is developed according to the functional design requirements of the temporary building. The single temporary building site and functional planning can be designed based on the high degree of parameterization and model sophistication of the BIM model. The functionality of each temporary building can be designed, such as the number and layout of rooms, the division of office and living areas, and the design of drainage pipes. The BIM model can fully simulate the effect after construction.

[0121] Step S315: Develop the association function between each temporary building and the surrounding environment according to the association requirements of the temporary building relationship.

[0122] It should be understood that according to the needs of temporary building relationships, the functions of linking each temporary building with the surrounding environment can be developed. The area, orientation, and relationship with surrounding vegetation and construction of each temporary building can be presented through the system, which can better conform to the terrain characteristics for site layout and optimization of temporary buildings, maximize land utilization while reducing the workload of excavation and filling.

[0123] Through the above scheme, this embodiment publishes the fusion model to the web page based on the B / S architecture; develops temporary building terrain matching and road planning interactive functions based on transportation needs to calculate road distances according to planned position relationships; develops a temporary building overall layout effect evaluation function based on temporary building layout needs to adjust temporary facilities according to the overall layout effect of temporary buildings; develops a single temporary building site planning function based on temporary building functional design needs; develops a function to associate each temporary building with the surrounding environment based on temporary building relationship association needs; it can greatly improve the convenience of planning and design, achieve a comprehensive view of the overall situation and focus on the details of each temporary building, and ensure the design safety of temporary construction.
