[0036] In related technologies, in order to efficiently carry out railway tunnel construction work, it is usually necessary to pre-construct a railway tunnel construction model to effectively carry out construction work according to the railway tunnel construction model. However, the existing methods for constructing railway tunnel construction models rely too much on manual modeling, lack constraints on construction standards of relevant industries in construction modeling and deepening, and it is also difficult to update the model in a timely manner according to the construction progress, resulting in low convenience and efficiency in constructing railway tunnel construction models and being difficult to meet actual needs.

[0037] To solve the above problems, the present disclosure provides a method, device and system for railway tunnel construction modeling and detailed design.

[0038] Figure 1 is a flowchart of a method for railway tunnel construction modeling and detailed design shown according to an exemplary embodiment. As Figure 1 shown, it should be noted that the method for railway tunnel construction modeling and detailed design in the embodiments of the present application is applied to a railway tunnel construction modeling and detailed design device. As Figure 1 shown, the method may include the following steps:

[0039] Step 101, obtain the target parameters of the tunnel to obtain a set of target parameters, and generate a cross-sectional graph of the tunnel according to the set of target parameters.

[0040] In some embodiments of the present application, before step 101, the method may further include: obtaining the route name, the horizontal curve information corresponding to the route name (including: coordinate X, coordinate Y, arc radius, length of the front transition curve, length of the rear transition curve, deflection angle, length of the front tangent, length of the rear tangent, mileage prefix of ZH, mileage of ZH), vertical curve information (including: mileage prefix of the grade change point, mileage number of the grade change point, design elevation, radius of the vertical curve), and chainage information (including: mileage prefix of the left side of the equal sign, mileage number of the left side of the equal sign, mileage prefix of the right side of the equal sign, mileage number of the right side of the equal sign), generating a horizontal curve model according to the read horizontal curve data, generating a vertical curve model according to the read vertical curve data, and adding the chainage information to the horizontal curve to generate a three-dimensional route model for generating a railway tunnel construction model according to the three-dimensional route model, that is, determining the overall route of the railway tunnel construction model based on the three-dimensional route.

[0041] In some embodiments of the present application, step 101 may specifically include the following steps:

[0042] Read the target parameters in the two-dimensional design drawing of the tunnel to obtain the set of target parameters; the target parameters include graphic elements in the two-dimensional design drawing of the tunnel and configuration parameters corresponding to the graphic elements;

[0043] Convert the graphic elements into corresponding feature line layers according to the target parameter set to obtain the cross-sectional graph of the tunnel for generating a 3D model.

[0044] Bind the configuration parameters corresponding to the feature line layer to the corresponding layer in the cross-sectional graph.

[0045] In some embodiments of the present application, a component library can be pre-constructed before step 101. The component library includes: a geological information library, a cross-section library, and a lining type library.

[0046] The geological information library can include: advanced horizontal drilling data, advanced horizontal drilling geological data, and geological radar geological data. The geological data all use their respective corresponding BIM models as storage media and are stored in the BIM models in the form of attribute data. The storage, modification, and reading of the data are all based on their respective corresponding BIM models.

[0047] The cross-section library can store rich tunnel cross-sectional model files. The tunnel cross-sectional files are used to describe the geometry and attribute information of the tunnel cross-section and are divided into two storage methods: the design data storage method; the tunnel cross-sectional geometry storage method. The stored data includes: basic design parameters of cross-section attributes, basic design information of the outer contour of the primary support, basic design information of the inner contour of the primary support, basic design information of the outer contour of the secondary lining, basic design information of the inner contour of the secondary lining, basic design information of the central drainage ditch, basic design parameters of the cable trough, basic design parameters of the drainage side ditch, basic design parameters of the pavement structure, basic design parameters of the invert backfill, and excavation method design parameters.

[0048] The lining type library can store lining type information under different surrounding rock grade conditions, which is summarized in the lining type library. Each lining type is associated with its corresponding tunnel cross-section, enhanced support, advanced support, etc. information. When the system is actually used, the lining type of the location of the proposed tunnel model can be first judged, and the corresponding tunnel cross-section can be recommended by the system. After the user approves and confirms, the next step of tunnel construction modeling and deepening work can be continued.

[0049] Step 102, generate the main construction structure model of the tunnel according to the preset configuration parameters, the target parameter set, and the cross-sectional graph.

[0050] In some other embodiments of the present application, the target parameters of the pre-configured tunnel can be directly obtained, and the main construction structure model of the tunnel can be directly generated according to the preset configuration parameters, the target parameter set, and the cross-sectional graph in the target parameters.

[0051] In one embodiment, the main construction structure model of the tunnel can be generated by stretching the matching cross-sectional graph according to the configuration parameters and the target parameter set.

[0052] In one embodiment, the configuration parameters may include various standards, specifications, and guiding principles related to railway tunnel construction. For example, engineering design documents, topographic and spatial data of alternative areas for temporary works, engineering geological and hydrological data, site layout condition data, temporary engineering component models, site forward design standards, construction specifications, project delivery requirements, safety and environmental protection standards, and construction specifications applicable to general and special sites.

[0053] Step 103: Generate a waterproof and drainage model and a pre-embedded model for the four-electrical interfaces in the main construction structure model according to the configuration parameters.

[0054] In some embodiments of the present application, the pre-embedded model for the four-electrical interfaces includes any one or more of a through-tube model, a catenary channel model, and a grounding terminal model.

[0055] In some embodiments of the present application, the waterproof and drainage model can be generated in the following manner: Based on the starting and ending mileage where the waterproof and drainage model is to be generated according to the route selection, obtain all the secondary lining model elements within this mileage range, sequentially obtain the bound tunnel cross-sectional data from these elements, and perform further mileage segmentation within the selected starting and ending mileage range according to the cross-sectional type. Within the selected starting and ending mileage range, sequentially generate the three-dimensional line information of the inner contour of the secondary lining in memory. Set the parameters of the waterproof and drainage model: for longitudinal and transverse drainage pipes, set the longitudinal spacing, pipe diameter, etc.; for waterproof sheets and geotextiles, set the offset distance, cut-off elevation, etc.; for longitudinal and transverse waterstops, set the longitudinal spacing, cross-sectional dimensions, etc. Based on the route, secondary lining inner contour data, and waterproof and drainage model parameters, sequentially generate the trajectory line, the cross-sectional polygon at the starting position of the trajectory line, and stretch it into a solid within the starting and ending mileage range.

[0056] In some embodiments of the present application, the following steps are used to generate the through-tube model:

[0057] Obtain the pre-drawn two-dimensional trajectory line of the through-tube; the size of the two-dimensional trajectory line of the through-tube corresponds to the cross-sectional size of the main construction structure model;

[0058] Obtain the configuration information of the through-tube model from the configuration parameters; the configuration information includes the first positional relationship between the through-tube model and the target tunnel model, and the first included angle between the through-tube and the target tunnel model;

[0059] Generate the three-dimensional trajectory line of the through-tube at the three-dimensional target position in the main construction structure model according to the two-dimensional trajectory line of the rail tube, the first positional relationship, and the first included angle;

[0060] Generate the three-dimensional model of the through-tube at the target position according to the three-dimensional trajectory line.

[0061] Among them, the size of the two-dimensional trajectory line 1 of the first pipeline corresponds to the size of the cross-section 2 of the target tunnel model; the first pipeline is an under-rail pipe or an under-groove pipe.

[0062] In one embodiment, the two-dimensional trajectory line 1 of the first pipeline can be drawn by the user on the cross-section of the target tunnel model. Additionally, the two-dimensional trajectory line 1 of the first pipeline can be drawn within the cross-section at the bottom of the secondary lining model 3 in the above-mentioned cross-section.

[0063] As Figure 2 shown, the under-rail pipes are all connected to the two cable trench 4 models in the tunnel, and the two cable trenches 4 are arranged on both sides of the internal space of the tunnel model.

[0064] Among them, the configuration information includes the first positional relationship between the first pipeline model and the target tunnel model 5, and the first included angle between the first pipeline and the target tunnel model 5.

[0065] In one embodiment, the first positional relationship can be the position of the first pipeline model on the mileage line 6 of the template tunnel model. The first included angle can be the included angle between the first pipeline model and the orthographic projection of the mileage line 6 on the XY plane.

[0066] Generate the three-dimensional trajectory line of the first pipeline at the three-dimensional target position in the target tunnel model according to the two-dimensional trajectory line of the first pipeline, the first positional relationship, and the first included angle.

[0067] It can be understood that in order to generate a three-dimensional pipeline model, it is necessary to convert the two-dimensional trajectory line into a three-dimensional trajectory line.

[0068] Therefore, in one embodiment, the three-dimensional trajectory line of the first pipeline can be generated at the three-dimensional target position in the target tunnel model 5 according to the two-dimensional trajectory line 1 of the first pipeline, the first positional relationship, and the first included angle.

[0069] Among them, the first positional relationship and the first included angle can be preset according to actual requirements.

[0070] In some embodiments of the present application, as Figure 3 、 Figure 4 shown, the first positional relationship is the two-dimensional intersection coordinates 9 of the first pipeline model and the tunnel mileage line 6 in the target tunnel model 5; the two-dimensional trajectory line 1 of the first pipeline is a two-dimensional trajectory line on the XY plane. Generating the three-dimensional trajectory line of the first pipeline at the three-dimensional target position in the target tunnel model according to the two-dimensional trajectory line of the first pipeline, the first positional relationship, and the first included angle can include:

[0071] Step a1: Determine the three-dimensional target position based on the position information of the target tunnel model 5 and the two-dimensional intersection coordinates 9.

[0072] In some embodiments of the present application, step a1 may specifically include the following steps:

[0073] Step a11: Obtain the position information of the target tunnel model 5.

[0074] Among them, the position information includes the horizontal curve information and vertical curve information of the target tunnel model 5.

[0075] Step a12: Determine the X-axis coordinate and Y-axis coordinate corresponding to the three-dimensional target position through the horizontal curve information and the two-dimensional intersection coordinates 9.

[0076] In one embodiment, the X-axis coordinate and Y-axis coordinate corresponding to the three-dimensional target position can be determined according to a preset first pipeline center line, that is, two-dimensional information is determined.

[0077] Step a13: Determine the Z-axis coordinate corresponding to the target position according to the vertical curve information.

[0078] In one embodiment, the Z-axis coordinate corresponding to the target position can be determined according to the vertical curve information, that is, elevation information is determined.

[0079] Step a14: Obtain the target position according to the X-axis coordinate, Y-axis coordinate corresponding to the three-dimensional target position, and the Z-axis coordinate corresponding to the target position.

[0080] Step a2: Move the first pipeline two-dimensional trajectory line 1 to the three-dimensional target position.

[0081] Step a3: Rotate the first pipeline two-dimensional trajectory line 1 according to the tunnel mileage line 6 to obtain a rotated pipeline two-dimensional trajectory line.

[0082] Among them, in one embodiment, the rotated pipeline two-dimensional trajectory line is perpendicular to the tunnel mileage line 6, and the rotated pipeline two-dimensional trajectory line is located in the YZ plane.

[0083] Step a4: Determine the target plane 8 perpendicular to the XY plane according to the first included angle and the three-dimensional target position.

[0084] Among them, the three-dimensional target position is located in the target plane 8.

[0085] In some embodiments of the present application, as Figure 3 shown, step a4 may specifically include the following steps:

[0086] Generate an intermediate plane including the three-dimensional target position based on the YZ plane;

[0087] Rotate the intermediate plane around the first straight line as the rotation axis to a position where the included angle with the tunnel mileage line 6 is the first included angle; the first straight line is perpendicular to the XY plane, and the X-axis coordinate and Y-axis coordinate of the first straight line are the intersection coordinates of the tunnel mileage line 6 and the first two-dimensional pipeline trajectory line 1.

[0088] In one embodiment, determine the YZ plane with the three-dimensional target position as the origin as the above intermediate plane, use the first straight line on the intermediate plane that includes the three-dimensional target position and is perpendicular to the XY plane as the rotation axis, and rotate the intermediate plane around the first straight line as the rotation axis to a position where the included angle with the tunnel mileage line 6 is the first included angle.

[0089] Step a5, project the first two-dimensional pipeline trajectory line 1 after the rotation process onto the target plane 8 to obtain the three-dimensional trajectory line.

[0090] Generate a first pipeline three-dimensional model at the target position according to the three-dimensional trajectory line.

[0091] In some embodiments of the present application, generating a first pipeline three-dimensional model at the target position according to the three-dimensional trajectory line may specifically include the following steps:

[0092] Step b1, obtain the cross-sectional information of the first pipeline from the configuration information.

[0093] Step b2, generate a cross-sectional graphic of the first pipeline at one end of the three-dimensional trajectory line according to the cross-sectional information.

[0094] Step b3, perform three-dimensional lofting processing on the cross-sectional graphic according to the three-dimensional trajectory line to obtain the first pipeline three-dimensional model 10.

[0095] In some embodiments of the present application, the configuration information further includes the first pipeline placement mileage, the number of placed pipes, and the placement spacing; the method may further include the following steps:

[0096] Based on the first pipeline three-dimensional model 10, generate a plurality of the first pipeline three-dimensional models 10 at corresponding positions in the target tunnel model 5 according to the first pipeline placement mileage, the number of placed pipes, and the placement spacing.

[0097] It can be understood that after generating one over-track pipe model, multiple corresponding over-track pipes can be generated in the target tunnel model 5 according to the first pipeline placement mileage, the number of placed pipes, and the placement spacing.

[0098] In some embodiments of the present application, such asFigure 4 As shown, when the first pipeline is an over-track pipeline, a plurality of three-dimensional models 10 of the first pipeline are generated at corresponding positions in the target tunnel model 5, including:

[0099] Step c1: Determine the target comprehensive chamber 7, and determine the center line of the target comprehensive chamber 7 according to the position information of the target comprehensive chamber 7.

[0100] Wherein, the center line is perpendicularly arranged to the target tunnel model 5.

[0101] It can be understood that the target comprehensive chamber 7 is used to place relevant equipment and the maintenance ends of the four-electrical circuits. Therefore, it is necessary to determine the positions of a plurality of three-dimensional models 10 of the first pipeline according to the position information of the target comprehensive chamber 7.

[0102] Step c2: Generate a plurality of first over-track pipeline models on one side of the center line according to the mileage of the first pipeline placement, the number of placed pipelines, and the placement spacing.

[0103] Wherein, each first over-track pipeline model is communicated with two cable trough 4 models in the target tunnel model 5; the two cable trough 4 models are arranged on both sides of the internal space of the target tunnel model 5; the cable trough 4 model on the side close to the target comprehensive chamber 7 is connected to the equipment model or the maintenance end model in the target comprehensive chamber 7.

[0104] Step c3: Generate a plurality of second over-track pipeline models that are mirror images of the plurality of first over-track pipeline models according to the center line.

[0105] Step c4: Obtain the plurality of three-dimensional models 10 of the first pipeline according to the plurality of first over-track pipeline models and the plurality of second over-track pipeline models.

[0106] In some embodiments of the present application, the following steps are used to generate the catenary trough model:

[0107] Obtain the three-dimensional coordinates of the target placement mileage of the catenary trough model in the main construction structure model;

[0108] Taking the three-dimensional coordinates of the target placement mileage as the center, within a preset angle range, generate a set of projection points of the three-dimensional coordinates of the target placement mileage on the inner side of the secondary lining model; the secondary lining model corresponds to the main construction structure model;

[0109] Generate a projection line based on the set of projection points;

[0110] Cut the projection line according to the preset catenary trough parameters to obtain a trough track line;

[0111] Generate the catenary channel model according to the channel trajectory line and the preset catenary channel parameters.

[0112] It should be noted that the mileage line can be pre-set on the central axis of the main construction structure model, and the mileage for Mr. Yu's verification target is placed on the mileage line.

[0113] As an example, the preset angle range can be from 1 degree to -89 degrees, and the above preset spacing can be 1 degree, that is, a projection point is generated every one-degree spacing, and a set of projection points of the three-dimensional coordinates of the target placement mileage on the inner side of the secondary lining model is obtained. The projection points in the set of projection points can be connected to obtain a projection line, the length of the channel trajectory line is determined according to the preset catenary channel parameters, and the projection line is trimmed according to the above length to obtain the channel trajectory line.

[0114] In some embodiments of the present application, a grounding terminal model library can also be established. Starting from the grounding terminal insertion point, parametric components are drawn in sequence. Each component can adjust the model size through parameters, and the components can be linked (that is, when the model size or position of one component changes, the other components in contact with it can synchronously adjust their positions). The made grounding terminal library file is put into the component library. Select the route model and the placement starting point, select the grounding terminal library file, input the placement information (placement horizontal spacing, elevation difference, placement direction, placement spacing, placement quantity, etc.), calculate the insertion point coordinates based on the route model, copy a grounding terminal model from the selected grounding terminal library file, and place it at the insertion point with the origin as the base point. Rotate the grounding terminal around the Z-axis so that the normal vector of its cross-section rotates to be consistent with the tangent vector direction of the route horizontal curve at this position. Set the layer, generate the code, and bind the component attributes for each grounding terminal model.

[0115] Step 104: Identify the cross-sections in the main construction structure model. For any two adjacent cross-sections, judge the relative position relationship between the two cross-sections, and perform transition processing on the two cross-sections according to the processing method corresponding to the relative position relationship to obtain the cross-section transition model corresponding to the two adjacent cross-sections.

[0116] Wherein, the cross-section transition model is a transition section model or a plug wall model.

[0117] In some embodiments of the present application, the two adjacent cross-sections include a first cross-section and a second cross-section. Step 104 may specifically include the following steps:

[0118] Obtain the first cross-section 11 area coordinates of the first cross-section 11 and the second cross-section 12 area coordinates of the second cross-section 12;

[0119] Generate a first minimum bounding box based on the coordinates of the area of the first cross-section 11, and generate a second minimum bounding box based on the coordinates of the area of the second cross-section 12;

[0120] For the first minimum bounding box and the second minimum bounding box, when one bounding box contains the other bounding box, determine that the relative position relationship is a size relationship;

[0121] When there is a partial area overlap between one bounding box and the other bounding box, determine that the relative position relationship is an offset relationship, and perform a transition process on the two cross-sections according to the first processing method to obtain the cross-section transition model;

At the positions of the starting mileage and the ending mileage of the transition section, the corresponding secondary lining model elements are obtained, the tunnel cross-section information bound thereto is read from the model elements, and converted into tunnel cross-section graphic data. Each component in the tunnel cross-section graphic data corresponding to the starting mileage and the ending mileage of the transition section is mapped and associated based on the component type. The tunnel cross-section graphics corresponding to the starting mileage and the ending mileage of the transition section are respectively drawn at the plane position and translated onto the three-dimensional route, and rotated along the Z axis so that the normal vector thereof is in the same direction as the tangent vector of the route horizontal curve. According to the mapping relationship of each component of the two tunnel cross-section graphics, stretching is respectively performed to form a solid, a layer is set for each component model, a code is generated, attributes are bound, and at the same time, corresponding nodes are generated in the model structure tree window. The original tunnel concrete model within the transition section range is trimmed and deleted to complete the processing of the transition section.

[0126] Step 105, using the configuration parameters and the target parameter set, perform engineering quantity statistics on the tunnel construction model and generate cutting list information for the tunnel construction model.

[0127] Wherein, the tunnel construction model includes the main construction structure model, the waterproof and drainage model, the pre-buried model for the four systems of electricity, communication, signal and ventilation, and the section transition model.

[0128] In one embodiment, the specific steps for obtaining the attribute information of "engineering quantity per meter" bound to each component element (i.e., sub-model) of the tunnel construction model, calculating the quantity information of the current component element according to the "engineering quantity per meter" information, and adding it to the "engineering quantity information object" are as follows: reading the attribute value of "engineering quantity per meter" from the component element; obtaining the "component engineering quantity object" of the same type as the current component element from the "engineering quantity information object"; parsing the attribute value of "engineering quantity per meter" to obtain the quantity information of each material stored therein; calculating the engineering quantity of each "material - specification" of this component (which can be further subdivided according to the surrounding rock grade of the current component); obtaining each "material - specification quantity object" from the "component engineering quantity object", and adding the engineering quantity in step A4 to the "material - specification quantity object" to complete the engineering quantity statistics.

[0129] In another embodiment, the cutting statistics range can be determined according to the preset starting mileage and ending mileage. All steel component model elements within the selected range are obtained (such as steel arch frames, advanced small conduits, steel mesh sheets, system bolts, locking bolts, main reinforcement bars, longitudinal reinforcement bars, hook reinforcement bars, etc.). The obtained steel component model elements are traversed, and the bound unit quantity attribute values and geometric attribute values are read, and classified and summarized according to "construction location, sub-item, material model, specification size, quantity". When all steel component model elements have been traversed, the initialization of the cutting data is completed, and the data is displayed on the interaction interface. The "construction location - sub-item" to be cut is selected, and the cutting data is modified. Based on the final data on the interface, the cutting list is exported.

[0130] Among them, the "construction location, component type" can be obtained according to the identity information attribute of the steel component model element; the sub-elements of the steel component model element are obtained, and the "sub-item" of each sub-element is determined according to the steel component type and sub-element type; the "unit quantity" attribute value is obtained from the steel component model element, and the "material model, specification size, unit quantity" of each relevant sub-item is parsed; according to the information obtained above, and the geometric attribute values (such as volume, length, etc.) of each sub-element, all "sub-item - material model - specification size - quantity" information of the current steel component model element is determined; all "sub-item - material model - specification size - quantity" information of the current steel component model element is added to a predefined cutting list data object (the definition of its class and sub-class / field is as follows: construction location - sub-item - material model - specification size - quantity).

[0131] In some embodiments of the present application, the method may further include the following steps:

[0132] In response to detecting the parameter change information of the tunnel construction model, the model parameters corresponding to the parameter change information in the tunnel construction model are updated using the parameter change information;

[0133] The tunnel construction model is updated using the updated model parameters.

[0134] As an example of a possible implementation, an advanced prediction model for tunnel update is selected (including: geological radar prediction model, advanced prediction fusion model), and the corresponding surrounding rock grade segmentation and lining type segmentation information within the update range is obtained. Within the update mileage range, the obtained surrounding rock grade segmentation information is used to update the original surrounding rock grade segmentation information, and the obtained lining type segmentation information is used to update the original lining type segmentation information. The updated lining type segmentation information is used to determine the segmented range of the tunnel concrete model to be updated. The corresponding tunnel cross-section name is obtained within each segmented range, and the tunnel cross-section information is read from the tunnel cross-section library. The tunnel cross-section information for update is used to generate a new tunnel concrete model. Layers are set for each generated tunnel concrete model, the original component attributes are inherited, new codes are generated based on the original corresponding model, and corresponding nodes are generated in the model structure tree window. The original tunnel concrete model is cropped and deleted to complete the update of the tunnel model based on geology.
