[0031] In order to build bridges more efficiently and accurately, the prior art typically requires the construction of a 3D bridge construction model, allowing construction to proceed based on the model. However, existing methods for constructing 3D bridge construction models often rely heavily on manual labor, resulting in complex operations and high demands on the personnel who construct the 3D model. Furthermore, relying too much on manual labor to complete the complex modeling process can lead to low efficiency and be prone to errors, compromising the accuracy of the bridge construction model.

[0032] In order to solve the above problems, the present disclosure provides a railway bridge construction modeling and in-depth design method for the entire life cycle, which obtains configuration parameters for generating a three-dimensional model of bridge construction; generates a precast beam model, a cast-in-place box beam model, a segment beam model, a bridge deck model, a pier model and an abutment model according to the configuration parameters and the preset section templates associated with the configuration parameters; generates a prestressed steel beam model and an anchor model associated with the prestressed steel beam model at a preset position of the cast-in-place box beam model according to the first parameter information, the preset tensioning pre-embedded constraint conditions and the steel beam configuration parameters; generates a longitudinal reinforcement model in the pier model according to the longitudinal reinforcement parameter information, and generates a stirrup reinforcement model in the pier model according to the stirrup parameter information; obtains the user-inputted data for the bridge No. 0 block model The initial intelligent line of steel bars is obtained from the configuration parameters, and multiple vertical steel bar installation positions and corresponding height parameters are obtained. According to the initial intelligent line of steel bars and the height parameters corresponding to the multiple vertical steel bar setting positions, corresponding vertical steel bar models are generated at each vertical steel bar setting position respectively; according to the precast beam model, cast-in-place box beam model, segmental beam model, bridge deck model, pier model, abutment model, prestressed steel bundle model, anchor model, stirrup model and stirrup model, a three-dimensional bridge construction model is generated, thereby realizing the generation of a three-dimensional bridge construction model according to the configuration information and the preset section template, improving the convenience of generating the three-dimensional bridge construction model, reducing the difficulty of building the three-dimensional bridge construction model, and thus improving the accuracy and efficiency of building the three-dimensional bridge construction model.

[0033] Figure 1 is a flowchart of a railway bridge construction modeling and in-depth design method for the entire life cycle according to an exemplary embodiment. Figure 1 As shown, it should be noted that the railway bridge construction modeling and in-depth design method for the entire life cycle of the embodiment of the present disclosure is applied to the railway bridge construction modeling and in-depth design device for the entire life cycle. Figure 1 As shown, the method may include the following steps:

[0034] Step 101: Obtain configuration parameters for generating a three-dimensional bridge construction model.

[0035] In the embodiment of the present disclosure, the above configuration parameters can be pre-set by the user according to actual needs.

[0036] Step 102 : Generate a precast beam model, a cast-in-place box beam model, a segmental beam model, a bridge deck model, a pier model, and an abutment model according to the configuration parameters and a preset section template associated with the configuration parameters.

[0037] The configuration parameters include first parameter information of the cast-in-place box girder model, steel bundle configuration parameters, longitudinal reinforcement parameter information, and stirrup parameter information.

[0038] It can be understood that the section template can be a template of the cross-section of a three-dimensional model, that is, it can be a two-dimensional drawing template formed by the cross-section. Since most structural component models in the bridge can be obtained by stretching the cross-sectional shape, the cross-sectional templates corresponding to different models can be stored in advance. When the model needs to be generated, the corresponding cross-sectional template is extracted, and the stretching processing is performed according to the preset size parameters and other configuration parameters to obtain the required model.

[0039] In some embodiments of the present disclosure, a cross-section template of a segmental beam may be generated in the following manner:

[0040] Enter the cross-sectional parameters of the standard segment beam: cross-sectional parameters, side guardrail parameters, middle guardrail parameters, and cross slope; enter the cross-sectional parameters of the constant height thickened segment beam: cross-sectional parameters, side guardrail parameters, middle guardrail parameters, cross slope, thickening and chamfer parameters; enter the cross-sectional parameters of the variable height segment beam: cross-sectional parameters (including top web chamfer, web slope, etc.), side guardrail parameters, middle guardrail parameters, and cross slope; enter the cross-sectional names of the standard segment, constant height thickened segment, and variable height segment beams respectively;

[0041] According to the cross-section drawing rules of standard segment, constant height thickened segment and variable height segment beam, and based on the above input parameters, graphics drawing and intersection calculation between graphics are performed to generate cross-section graphics;

[0042] Storing design data in cross-sectional drawings;

[0043] Save the cross-section template in the segmental beam cross-section template library.

[0044] In some embodiments of the present disclosure, a T-beam model can be generated in the following manner: enter general setting information, T-beam mid-span, end, diaphragm cross-section information, facade information, continuous end information and tooth block size setting information in the prefabricated T-beam editor to obtain all physical dimension information for creating the T-beam model. According to the total width of the bridge deck and the number of beams, calculate and obtain the coordinate values ​​of the starting and ending points of the center line of each beam. According to the cross-section of the T-beam mid-span, stretch along the center line of each beam to obtain the initial T-beam body. According to the information such as the T-beam end, diaphragm setting, facade, etc., create other bodies or cut or merge with the initial T-beam body to obtain the final T-beam body model. Create a wet joint model between adjacent T-beam models. First, obtain the relative side profiles of adjacent T-beams, and stretch out the wet joint model according to the two profiles. Store all T-beam models and wet joint models together in the newly created T-beam model, and convert all information in the T-beam editor into strings and bind them to the model in attribute mode.

[0045] In some embodiments of the present disclosure, a bridge plane model can be generated in the following manner: obtaining a preset bridge starting pile number, basic bridge parameters, and the route where the bridge is located, generating a bridge plane sub-model according to the above basic parameters, and generating a bridge plane model based on the bridge plane sub-model, the route where the bridge is located, and the bridge starting pile number.

[0046] For example, you can retrieve a preset bridge element and the left and right side lines of the bridge. In the interactive interface, you can set the starting distance for placement, select the desired bridge cross-section template from the bridge deck template library, and set the cross-section placement spacing. Then, you can match the edge lines with the points in the bridge cross-section template. Then, you can extrude the bridge cross-section along the route to generate a 3D bridge deck model.

[0047] The specific steps for generating a 3D bridge deck model by stretching the bridge deck cross section along the route are as follows:

[0048] For each mileage node, draw a two-dimensional cross-section of the bridge deck with the origin (X=0, Y=0) on the XY plane at the mileage node as the base point; move the two-dimensional cross-section of the bridge deck to the corresponding mileage position on the route; rotate the bridge deck cross-section around the X and Z axes to align it with the actual orientation; obtain the lateral and vertical offset data of the selected edge line in the bridge deck cross-section at the current mileage relative to the route; and adjust the bridge deck cross-section based on the above lateral and vertical offset data.

[0049] Based on all the placed bridge deck cross sections, stakeout is performed to generate the bridge deck pavement entity.

[0050] In one embodiment, the segment beam model can be generated in the following manner: select the route model, select the starting mileage and the ending mileage, input the segment division and longitudinal section setting information (including the starting mileage, length, template name, transition type, parabola index), and the hollow section setting information (including the distance from the starting point of the hollow section to the starting point of the height-changing section, the bottom plate thickness at the hollow starting point, the bottom plate thickness at the hollow end point, and the distance from the end point of the hollow section to the center of the pier). Place the corresponding cross-section templates in each stage in turn, and stretch along the route to generate a three-dimensional model. Adjust the bottom plate thickness of the three-dimensional model along the route according to the longitudinal section setting information, and complete the gradual change processing at the sudden change position. Adjust the top and bottom plate parameters of the height-changing section model along the route according to the hollow section setting information to achieve continuous changes in the cavity, and perform chamfering processing at the same time.

[0051] In some embodiments of the present disclosure, the preset section template is obtained from a pre-built bridge model library; the model library includes any one or more of the following: a cast-in-place box girder cross-section template library, a bridge deck template library, a prefabricated T-beam model library, and bridge piers.

[0052] As an example of a possible implementation, a bridge structure hierarchy table can be generated. Upon system startup, the data in this table is loaded to obtain the bridge structure hierarchy information. A model structure tree is configured for each bridge component, including the primary node type, secondary node type, node name, and corresponding modeling process. Once the model structure tree is configured, subsequent bridge modeling can be synchronized with the modeling process to generate the model structure tree, combining this configuration information. This facilitates quick search and manipulation of local components.

[0053] Step 103: Generate a prestressed steel strand model and an anchor model associated with the prestressed steel strand model at a preset position of the cast-in-place box girder model according to the first parameter information, the preset tensioning and embedding constraint conditions, and the steel strand configuration parameters.

[0054] It should be noted that the preset tensioning and pre-embedding constraint conditions may be relevant specifications and standards for tensioning and pre-embedding.

[0055] In one embodiment of the present disclosure, according to the parameter information of the cast-in-place box girder model and the cross-sectional dimension information of the cast-in-place box girder model, and in accordance with the tensioning pre-embedded constraint conditions, parameters are set for the three different types of steel bundles: top plate steel bundle, web steel bundle, and bottom plate steel bundle; the position of each steel bundle is further determined according to the cross-sectional dimensions of the end, mid-span, and continuous end of the cast-in-place box girder model; and the horizontal and vertical bending parameters of the steel bundle are set. For each type of steel bundle, based on the collision relationship between the steel bundle and the steel bar and in accordance with the specification requirements, the spatial point coordinates of each steel bundle within the mileage range of the route where the box girder model is located are calculated, and a prestressed steel bundle model is generated based on the spatial point coordinates. The parameters of the tensioning grooves and tooth blocks at the left and right ends of the steel bundle are set, and the anchor model to be placed is selected; the tensioning groove model and tooth block model are created at both ends of the steel bundle in accordance with the parameters of the tensioning groove and tooth block, and the anchor model to be placed is placed based on the positions of the tensioning groove model and tooth block model.

[0056] In one embodiment, a steel bundle node may be added under the corresponding bridge structure tree and the corresponding connection node to form a complete steel bundle structure tree, and corresponding attributes may be bound to the steel bundle model.

[0057] Step 104 : generating a longitudinal reinforcement model in the pier model according to the longitudinal reinforcement parameter information, and generating a stirrup reinforcement model in the pier model according to the stirrup parameter information.

[0058] In some embodiments of the present disclosure, generating a longitudinal reinforcement model in the pier model according to the longitudinal reinforcement parameter information in step 104 may specifically include the following steps:

[0059] Step a1: Select a target pier model and obtain the top surface contour line and the bottom surface contour line of the target pier model.

[0060] Step a2: determining a first starting point of a first longitudinal rib on the top surface contour line, and determining a first end point of the first longitudinal rib on the bottom surface contour line.

[0061] Step a3: generating a longitudinal reinforcement model of the first longitudinal reinforcement according to the first starting point and the first end point.

[0062] In one embodiment, a line connecting the first starting point and the first end point may be determined as a trajectory line of the first longitudinal reinforcement, and a longitudinal reinforcement model may be generated according to preset longitudinal reinforcement parameter information and the trajectory line.

[0063] For example, the longitudinal reinforcement parameter information may include steel bar specifications, protective layer thickness, longitudinal reinforcement spacing, starting end extension length, ending end extension length, starting end hook information, and ending end hook information.

[0064] It should be noted that the longitudinal reinforcement model can be perpendicular to the center line of the pier model, that is, the longitudinal reinforcement model is parallel to the pier model.

[0065] Step a4: obtaining the longitudinal reinforcement protective layer thickness in the longitudinal reinforcement parameter information, and translating the longitudinal reinforcement model toward the axis direction of the target pier model according to the longitudinal reinforcement protective layer thickness to obtain the translated longitudinal reinforcement model.

[0066] It is understandable that the longitudinal reinforcement model should be set inside the pier model rather than on the outer surface of the pier model. Therefore, after the longitudinal reinforcement model is generated based on the top and bottom contour lines of the target pier model, the longitudinal reinforcement model needs to be translated toward the axis of the target pier model according to the thickness of the longitudinal reinforcement protective layer to obtain the translated longitudinal reinforcement model.

[0067] Step a5: generating a three-dimensional point set of longitudinal reinforcement positions according to the arrangement parameters of the longitudinal reinforcement model in the longitudinal reinforcement parameter information and the position information of the translated longitudinal reinforcement model.

[0068] It is understandable that multiple longitudinal reinforcements need to be set in a pier to ensure that the pier has sufficient supporting capacity. The arrangement of multiple longitudinal reinforcement models in the same pier can be pre-set, that is, the above-mentioned arrangement parameters.

[0069] In one embodiment, the placement position of each longitudinal reinforcement model in the pier model is determined according to the arrangement parameters of the longitudinal reinforcement model in the longitudinal reinforcement parameter information and the position information of the translated longitudinal reinforcement model, and a three-dimensional point set of the longitudinal reinforcement position is obtained according to the placement position.

[0070] Step a6: for each three-dimensional point coordinate in the three-dimensional point set of longitudinal reinforcement positions, determine the top surface elevation and the bottom surface elevation of the pier model corresponding to the three-dimensional point coordinate.

[0071] It is understandable that the top and bottom surfaces of the pier model are not horizontal. There may be different elevations of the top surface or different areas of the ground, and the elevation of the longitudinal reinforcement needs to be adapted to the elevation of the top and bottom surfaces of the pier model.

[0072] Therefore, it is necessary to determine the top surface elevation and the bottom surface elevation of the pier model corresponding to each three-dimensional point coordinate in the three-dimensional point set of the longitudinal reinforcement position.

[0073] Step a7: for each three-dimensional point set, based on the three-dimensional point set and the top surface elevation and bottom surface elevation corresponding to the three-dimensional point set, generate a longitudinal reinforcement model corresponding to the three-dimensional point set.

[0074] In one embodiment, the position, top elevation, and bottom elevation of each longitudinal reinforcement model are determined based on the three-dimensional point set and the top surface elevation and bottom surface elevation corresponding to the three-dimensional point set, thereby generating a longitudinal reinforcement model corresponding to each three-dimensional point coordinate in the three-dimensional point set, that is, the top elevation of each longitudinal reinforcement model corresponds to the top surface elevation of its location, and the bottom elevation of each longitudinal reinforcement model corresponds to the bottom surface elevation of its location.

[0075] In some embodiments of the present disclosure, generating a stirrup model in the pier model according to the stirrup parameter information in step 104 may specifically include the following steps:

[0076] Step b1: in response to receiving an instruction to generate a stirrup model in a target pier model, determining the top surface contour line or the bottom surface contour line as an initial contour line of the stirrup.

[0077] It can be understood that the stirrups of the bridge are annular and are arranged perpendicular to the longitudinal reinforcement. Therefore, the initial contour line of the stirrups can be determined based on the top surface contour line or the bottom surface contour line.

[0078] Step b2, obtaining the position information of the longitudinal reinforcement model, the stirrup radius parameter in the configuration parameters, and the protective layer thickness information.

[0079] Step b3: shrinking the initial contour line inward according to the stirrup radius parameter and the position information of the longitudinal reinforcement model to obtain a target contour line.

[0080] It is understandable that the stirrups need to be set inside the pier model, so the initial contour line can be contracted inward according to the stirrup radius parameters and the position information of the longitudinal reinforcement model to obtain the target contour line.

[0081] Step b4: generating a first stirrup model according to the protective layer thickness information and the target contour line.

[0082] Step b5: obtaining the stirrup elevation configuration parameters in the configuration parameters and the elevation information of the pier model, and determining the elevations of the plurality of second stirrup models to be generated in the pier model.

[0083] Step b6: generating a plurality of second stirrup models according to the respective elevations of the first stirrup model and the second stirrup model.

[0084] In one embodiment, the number of stirrup models required to be configured in the pier model and the elevation of each stirrup model can be determined based on the elevation information of the pier model and the stirrup elevation configuration parameters, and multiple second stirrup models can be generated according to the respective elevations of the first stirrup model and the second stirrup model.

[0085] Step 105: Obtain the initial intelligent steel bar line for the bridge block model input by the user, obtain multiple vertical steel bar installation positions and corresponding height parameters from the configuration parameters, and generate corresponding vertical steel bar models at each vertical steel bar setting position based on the initial intelligent steel bar line and the height parameters corresponding to the multiple vertical steel bar setting positions.

[0086] It should be noted that the length and position of the smart line can be adjusted according to the location of the steel bars, so that users only need to draw the smart line once to generate multiple vertical steel bar models that can adapt to different positions (that is, adapt to different length requirements), which greatly reduces the user's operation steps and improves the convenience and efficiency of model generation.

[0087] In some embodiments of the present disclosure, generating a corresponding vertical reinforcement model at each vertical reinforcement setting position according to the height parameters corresponding to the initial reinforcement smart line and the plurality of vertical reinforcement setting positions may include the following steps:

[0088] For each vertical reinforcement setting position, placing an initial reinforcement smart line;

[0089] According to the height parameter corresponding to the vertical steel bar setting position, the elevation parameter of the steel bar initial smart line in the pier model is adjusted to obtain the steel bar trajectory line corresponding to the vertical steel bar setting position;

[0090] Based on the steel bar trajectory line, a vertical steel bar model is generated at the vertical steel bar setting position.

[0091] In one embodiment, for each vertical steel bar setting position, an initial steel bar smart line is placed, which is equivalent to generating an initial steel bar trajectory line at the target position. According to the height parameters corresponding to the vertical steel bar setting position, the elevation parameters of the initial steel bar smart line in the pier model are adjusted, that is, the top elevation and bottom elevation of the initial steel bar smart line are adjusted to adapt to the length requirements of the vertical steel bars at different positions. Based on the steel bar trajectory line, a vertical steel bar model is generated at the vertical steel bar setting position.

[0092] Step 106: Generate the three-dimensional bridge construction model based on the precast beam model, cast-in-place box beam model, segmental beam model, bridge deck model, pier model, abutment model, prestressed steel bundle model, anchor model, stirrup model and stirrup model.

[0093] In one embodiment, a precast beam model, a cast-in-place box beam model, a segmental beam model, a bridge deck model, a pier model, an abutment model, a prestressed steel bundle model, an anchor model, a stirrup model and a stirrup model can be assembled according to preset positional relationship conditions to obtain a three-dimensional bridge construction model. The above-mentioned multiple models can also be generated one by one according to the above-mentioned preset positional relationship conditions to finally obtain a three-dimensional bridge construction model.

[0094] In some embodiments of the present disclosure, after step 106, the method may further include the following steps:

[0095] Step c1: Obtain parameter information of the device model to be configured or the functional space to be configured.

[0096] In one embodiment, the model to be configured may be any one or more of the following models:

[0097] Passage model for personnel passage, vibration channel model, ventilation hole model, and spare prestressed steel strand placement space model.

[0098] Step c2: determining the target position and target size of the device model to be configured or the functional space to be configured according to the parameter information.

[0099] The target position is a position in the three-dimensional model of the bridge construction.

[0100] Step c3: cutting the three-dimensional bridge construction model at the target position to obtain a reserved space corresponding to the target size.

[0101] The reserved space is used to place the device model to be configured or to configure the function space to be configured.

[0102] In some embodiments of the present disclosure, after step c3, the method may further include the following steps:

[0103] Step d1, determining the type of the reserved space;

[0104] Step d2, when the type meets the preset conditions, obtaining the steel bar path corresponding to the steel bar associated with the reserved space;

[0105] Step d3, determining the reserved space as an obstacle, and replanning the steel bar path based on the obstacle to obtain a planned steel bar path;

[0106] Step d4: updating the steel bar model according to the planned steel bar path.

[0107] In one embodiment, when the type of reserved space meets the preset conditions, for example, when the reserved space is a passage model for personnel passage, it is necessary to re-plan the steel bars in the area where the reserved space is located, so as to reserve the passage space while ensuring the stability of the bridge.

[0108] In some embodiments of the present disclosure, after step c3, the method may further include the following steps:

[0109] Obtaining a temporary construction model associated with the reserved space;

[0110] The temporary construction model is adjusted according to the configuration parameters of the reserved space.

[0111] In one embodiment, a corresponding temporary construction model, such as a temporary support model, is configured in the three-dimensional model of bridge construction according to actual needs. After a new reserved space is generated in the model, the demand for the temporary construction model will also change accordingly. Therefore, it is necessary to obtain the temporary construction model associated with the reserved space and adjust the temporary construction model according to the configuration parameters of the reserved space, so as to avoid unreasonable problems caused by the generation of the reserved space and affect the rationality of the model construction.

[0112] In some embodiments of the present disclosure, after step 106, the method may further include the following steps:

[0113] Determine a construction model for the sensor model to be placed; the construction model is a sub-model in the construction three-dimensional model;

[0114] Acquire a surface or line in the constructed model where the sensor model is to be placed;

[0115] Determine the installation position and placement direction of the sensor model on the surface or line according to any one or more of the detection object, detection head, and detection mileage on which the sensor model is to be placed;

[0116] The sensor model is placed in the construction model according to the installation position and the placement direction.

[0117] It should be noted that a large number of sensors need to be set up in the three-dimensional model of bridge construction. These sensors are used to collect relevant data during the bridge construction process. Due to the large number of sensors and certain requirements for their placement, the sensor model needs to be reasonably placed according to preset conditions.

[0118] In one embodiment, the sensor model to be placed and the construction model of the sensor model to be placed in the three-dimensional construction model can be determined based on the preset sensor model type, quantity and placement position parameters, and the surface or line on which the sensor model is to be placed in the construction model is obtained. According to any one or more of the detection object, detection head, and detection mileage of the sensor model to be placed, the installation position and placement direction of the sensor model on the surface or line are determined, that is, the sensor model should not intersect with other models, and the probe of the sensor model should be able to be aligned with the object to be detected. The sensor model is placed in the construction model according to the installation position and the placement direction.

[0119] In some embodiments of the present disclosure, a model structure tree can be displayed on the interactive interface of the terminal device, and the bridge component model involved in this cutting can be selected. The system automatically obtains all the steel bar models corresponding to the selected bridge component model. Based on the steel bar parameters bound to each type of steel bar corresponding to each bridge component, preliminary steel bar cutting information is generated and displayed on the interactive interface. Each cutting information is modified, merged, and split to form a final steel bar cutting list. The data is converted according to the data format required by the platform system connected to the intelligent steel bar processing equipment, and exported to the platform system connected to the intelligent processing equipment to obtain the returned information and complete the steel bar cutting list data transmission. The platform system connected to the intelligent processing equipment is operated to perform intelligent processing of steel bars.

[0120] In other embodiments of the present disclosure, it is possible to customize attribute information, export an Excel table of attribute information of all bridge component models, supplement the model construction information in the table, and then bind the construction attributes to each bridge component model by importing the construction attribute function. According to the data format requirements of the construction management platform, the attribute information of all models is exported and imported into the construction management platform together with the bridge BIM model. On the construction management platform, the imported attribute data is parsed and matched with the imported bridge component models. The bridge component models are connected to equipment (such as concrete pouring equipment), and the equipment reads construction information (such as the amount of concrete poured this time) from the BIM model, inputs setting information (such as pouring steps, pouring speed, alarm conditions, termination conditions, etc.), and combines with the sensor detection devices related to on-site construction (such as pouring) to carry out the entire construction (such as pouring) process, and save and export the entire construction (such as pouring) process information and detection monitoring information for backtracking, inspection and delivery.
