Description

Technical Field

[0001] This application relates to the field of tunnel engineering technology, and in particular to the design method, apparatus, equipment and storage medium for connecting passages in twin-track tunnels. Background Technology

[0002] Traditional connecting passage design typically requires designers to manually calculate tunnel length and end mileage based on route drawings and tunnel end manhole drawings. They then need to identify the lowest points within the tunnel area, considering the longitudinal profile design, and determine whether each lowest point requires a connecting passage / pump station. After initially estimating the number of connecting passages needed within the tunnel area, each passage must be manually laid out, and the distance between adjacent passages must be checked against specifications. If any exceed these limits, a comprehensive adjustment is necessary. Once a feasible solution is confirmed, the elevation and mileage of each connecting passage must be manually measured and marked. This entire design process is extremely cumbersome, and repeated adjustments are highly likely during the review process, leading to errors by designers, wasted time, and other problems. It is a highly inefficient design method.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0021] When multiple target points corresponding to the first tunnel line and the second tunnel line are within the tunnel mileage range of the double-track tunnel to be designed, the step of matching neighboring points based on the basic information of the multiple target points corresponding to the first tunnel line and the second tunnel line is executed.

[0039] The preliminary design scheme is analyzed according to the scheme evaluation principles;

[0040] When the scheme analysis result is a reasonable result as preset, the design scheme of the connecting passage of the double-track tunnel to be designed is determined according to the preliminary design scheme.

[0041] In addition, to achieve the above objectives, this application also proposes a design device for a connecting passage of a double-track tunnel.

[0065] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0066] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0067] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0068] The main solution of this application embodiment is as follows: Based on the longitudinal slope information of the double-track tunnel to be designed, determine the basic information of multiple target points corresponding to the first tunnel line and the second tunnel line respectively; perform neighbor point matching based on the basic information of the multiple target points corresponding to the first tunnel line and the second tunnel line respectively, and determine multiple initial connecting passages / pump houses and the center mileage information of each initial connecting passage / pump house based on the point matching results; divide the first tunnel line into multiple evacuation sections by using the center mileage information of each initial connecting passage / pump house and the boundary mileage information of the tunnel ventilation shaft; determine the number of target passages in each evacuation section based on the segment spacing and fire evacuation spacing of the multiple evacuation sections of the first tunnel line; determine multiple target connecting passages and the center mileage information of each target connecting passage based on the number of target passages in each evacuation section and the center mileage information of each initial connecting passage / pump house; and determine the connecting passage design scheme of the double-track tunnel to be designed based on the center mileage information of each target connecting passage.

[0069] Currently, urban rail transit is experiencing rapid growth, and shield tunneling, as a common construction method for rail transit engineering, has made shield tunnels the main structural form of urban subway tunnels. To meet the needs of passenger evacuation, tunnel drainage, fire prevention, and firefighting, double-track tunnels of a certain length typically have connecting passages between the left and right tracks. Based on the longitudinal profile design of the line and the requirements for tunnel waterproofing and drainage, a wastewater pumping station is usually required at the lowest point of the line. Generally, to minimize project costs, the wastewater pumping station and connecting passage are combined, meaning the connecting passage houses the wastewater pumping station, as well as pipelines and manholes for wastewater pumping and personnel maintenance; this is commonly referred to as the connecting passage / pumping station. Currently, the layout of communication channels is mostly carried out using manual drawing design. On the one hand, manual drawing is inefficient, requiring a lot of manpower and time, and the intellectual achievements of designers are completely solidified in the drawings, which is not conducive to the transmission of information downstream and the use of computers for digital integration and application. On the other hand, the design process is mostly based on the subjective decisions of designers, and less experienced designers often tend to overlook some design details, leading to errors in the solution decision. Furthermore, the review and approval of drawings are difficult, making it hard to propose reasonable suggestions based on taking into account all relevant business information.

[0070] Traditional connecting passage design typically requires designers to manually calculate tunnel length and end mileage based on route drawings and tunnel end manhole drawings. They then need to identify the lowest points within the tunnel area, considering the longitudinal profile design, and determine whether each lowest point requires a connecting passage / pump station. After initially estimating the number of connecting passages needed within the tunnel area, each passage must be manually laid out, and the distance between adjacent passages must be checked against specifications. If any exceed these limits, a comprehensive adjustment is necessary. Once a feasible solution is confirmed, the elevation and mileage of each connecting passage must be manually measured and marked. This entire design process is extremely cumbersome, and repeated adjustments are highly likely during the review process, leading to errors by designers, wasted time, and other problems. It is a highly inefficient design method.

[0071] The review process for connecting corridor layout plans is challenging because the design information is entirely fixed on two-dimensional drawings. Reviewers typically need to thoroughly understand the entire route plan, verifying that each connecting corridor meets the specifications, checking for issues with mileage markings, and evaluating the plan based on their experience, offering optimization suggestions. This entire review process is labor-intensive and time-consuming, primarily due to the lack of intuitive design information and inefficient data transmission, leading to repetitive work and making the review of connecting corridor layout plans difficult.

[0072] Analyzing the above process, this design approach is mainly due to the poor correlation between relevant business information. Designers collect all information and then make subjective decisions to form the final design drawings, which has pain points such as poor fault tolerance, lack of intuitiveness in the design process, and difficulty in reviewing the design.

[0073] Specifically, traditional communication channel deployment schemes mainly suffer from the following technical problems:

[0074] 1. Traditional connection channel layout design relies entirely on manual calculations by designers, resulting in low design efficiency and a high probability of errors: Traditional connection channel layout design requires designers to visually interpret drawings to collect upstream professional information and manually calculate the mileage of the lowest point, which is inefficient; connection channel design generally requires repeated adjustments and comparisons, consuming a lot of manpower and time; the drawings are complex, and the possibility of errors in visual identification is high, and repeated adjustments further increase the possibility of errors.

[0075] 2. Traditional communication channel layout design processes are not intuitive, and the visualization of scheme information is poor, which is not conducive to later review and verification: The traditional communication channel layout design process requires designers to repeatedly review the completed design content, and the design information is not linked before and after, making the design process not intuitive; the information of traditional communication channel layout schemes is fixed on drawings, and the review process involves a lot of repetitive work to extract scheme information, resulting in poor visualization of the results; business information linkage is not achieved, and reviewers, after becoming familiar with the overall scheme, rely on experience to subjectively decide the rationality of the scheme, resulting in poor fault tolerance.

[0076] 3. Traditional communication channel deployment schemes lack digital and integrated management, hindering automated and batch processing of business processes and increasing the difficulty of subsequent data statistics. In traditional schemes, upstream input, scheme design, and scheme verification are separate processes, lacking correlation and integrated management. No computer-recognizable relationships exist between them, preventing rapid, integrated deployment across the entire process. Furthermore, this lack of correlation prevents the one-click expansion of other functions such as design optimization, quantity surveying, design drawing generation, and cost verification. Repeated manual backtracking and inter-departmental communication are required, consuming time and effort and slowing down overall departmental efficiency.

[0077] To address the aforementioned issues, this application provides a design method for connecting passages in a dual-track tunnel, which solves the above problems and achieves the following technical effects: 1. By combining computer technology, the design of connecting passage layout schemes is batched and automated, significantly improving design efficiency. Human-computer interaction design improves design and reduces error rate: The computer automatically reads upstream professional information, completes internal calculations and analysis, extracts key data, and reduces communication costs between disciplines; the batch automatic calculation method obtains the minimum point mileage and completes matching, automatically generating a uniform distribution scheme for connecting passages; interactive dynamic adjustment reduces the time required for scheme adjustment, significantly improving design efficiency; the structured storage of design information can further realize automatic drawing and annotation of drawings, eliminating the traditional manual drawing and annotation design method, and fully reducing labor and time consumption. 2. The integrated display of design-related information via a user interface allows for synchronized changes in the design scheme after adjustments. The computer automatically analyzes and evaluates the current scheme, significantly improving design quality. This enables digital design of connecting passageway layout schemes, with relevant information integrated and displayed in real-time on the interactive interface, eliminating the need for repeated manual extraction of drawing information and greatly improving the readability of the scheme data. Designers can adjust scheme parameters in real-time, with related design information changing in tandem, providing a clear view of design data changes and facilitating scheme decision-making. The computer automatically evaluates the engineering cost and drainage of the scheme using built-in rules, comprehensively assessing the rationality of the scheme and compensating for the incompleteness and lack of systematic consideration by humans, thus improving the fault tolerance of the design process. 3. The digital integration and extended application of connecting passageway layout scheme design lay the foundation for the automation and batch processing of subsequent business processes. From the structuring of upstream input data to the digital design of connecting passageway schemes, and then to the combination of automatic and manual verification of design schemes, various discrete data related to connecting passageway scheme design are digitally integrated, forming an integrated solution for connecting passageway layout scheme design. It also provides interfaces for various automated output methods based on the aforementioned integrated data, such as engineering quantity statistics and automatic tunnel design drawings, to improve the efficiency of the entire process of connecting passage layout design. This provides strong data support for achieving a win-win situation of safety and cost optimization in the final connecting passage layout design, and improves the work efficiency of the entire department.

[0078] This application determines the basic information of multiple target points corresponding to the first and second tunnel lines based on the longitudinal slope information of the double-track tunnel to be designed. It then performs neighbor point matching based on the basic information of the multiple target points corresponding to the first and second tunnel lines, and determines multiple initial connecting passages / pump houses and their center mileage information based on the matching results. The first tunnel line is then segmented using the center mileage information of each initial connecting passage / pump house and the boundary mileage information of the tunnel ventilation shaft, resulting in multiple evacuation segments. The number of target passages in each evacuation segment is determined based on the segment spacing and fire evacuation spacing. Multiple target connecting passages and their center mileage information are then determined based on the number of target passages in each evacuation segment and the center mileage information of each initial connecting passage / pump house. Finally, the design scheme for the connecting passages of the double-track tunnel to be designed is determined based on the center mileage information of each target connecting passage. This method achieves batch and automation of connecting passage layout design, significantly improving design efficiency and reducing error rates, eliminating traditional manual drawing design methods, and greatly reducing labor and time consumption.

[0079] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions, a dual-track tunnel communication channel design device, etc. The following description uses a dual-track tunnel communication channel design device as an example to illustrate this embodiment and the subsequent embodiments.

[0080] Based on this, embodiments of this application provide a design method for a connecting passage in a dual-track tunnel, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the design method for the connecting passage of a dual-track tunnel in this application.

[0081] In this embodiment, the design method for the connecting passage of the dual-track tunnel includes steps S10 to S60:

[0082] Step S10: Based on the longitudinal slope information of the double-track tunnel to be designed, determine the basic information of multiple target points corresponding to the first tunnel line and the second tunnel line respectively.

[0083] It should be noted that the dual-track tunnel to be designed refers to a tunnel containing two driving lanes (left and right) that requires connecting passage design. The tunnel can be an urban subway tunnel or other traffic tunnel; this embodiment does not impose any restrictions. However, this embodiment uses an urban subway tunnel as an example for illustration. In this embodiment, a CAD platform is built into the connecting passage design equipment for the dual-track tunnel.

[0084] It is understood that the longitudinal slope information of the route includes, but is not limited to, the data necessary for determining the lowest point on the left and right lines of the double-track tunnel to be designed. The data necessary for determining the lowest point includes, but is not limited to, the mileage of the slope change point, the elevation of the slope change point, the design slope before / after, the design slope length before / after, and the radius of the vertical curve, etc. In this embodiment, the lowest point refers to the relative lowest point of the route in space, rather than the absolute lowest point.

[0085] In the specific implementation, the longitudinal slope information of the line is filled in manually by the designer or automatically generated by other software modules. The data in the longitudinal slope information can be read into the computer memory and saved to the local database file. The import process of the longitudinal slope information can be carried out by manually importing files, or by calling the network service interface and parsing the returned data, and finally importing the longitudinal slope information into the computer memory. Other methods can also be used, and this embodiment does not limit them.

[0086] It should be noted that the first tunnel line and the second tunnel line refer to the two driving lines existing in the double-track tunnel to be designed. The first tunnel line and the second tunnel line can be the right line or the left line in the double-track tunnel to be designed, respectively. This embodiment does not limit this, but in this embodiment, the first tunnel line is the right line and the second tunnel line is the left line as an example for explanation.

[0087] Understandably, based on the longitudinal slope information of the dual-track tunnels to be designed, and using the criterion of "negative slope at the front and positive slope at the rear," the computer batch-determines whether there are lowest points at the longitudinal slope change points of the first and second tunnel lines. The line calculation module calculates and saves the mileage, elevation, coordinates, and other information of the lowest points of the first and second tunnel lines. In this embodiment, the lowest points existing on the first and second tunnel lines are the multiple target points existing on the first and second tunnel lines, respectively, and the mileage, elevation, and coordinates of the lowest points constitute the basic information of each target point.

[0088] In this specific implementation, the mileage mentioned above and subsequently refers to the mileage markers of linear engineering projects such as roads or railways. Mileage markers are used to indicate any position on the route; mileage markers must not be repeated, and there is a one-to-one relationship between mileage markers and route positions. Each mileage marker includes both a mileage prefix and a mileage number. Without chainage breaks, the mileage number represents the horizontal distance from the starting point of the route along the centerline. With chainage breaks, the calculation of the horizontal distance must consider the impact of the chainage break. A chainage break refers to a measure implemented to ensure the one-to-one relationship between mileage markers and route positions when mileage markers are discontinuous due to segmented measurements, partial route changes, or measurement errors during the linear engineering design process. A negative front slope and a positive rear slope means that in the design of tunnels, the front part of the tunnel (the side entering the tunnel) slopes downwards, while the rear part (the side exiting the tunnel) slopes upwards. This design helps vehicles enter and exit tunnels more smoothly, reducing speed changes and driving discomfort caused by slope variations. This design is typically used in long tunnels or tunnels requiring significant gradient changes to improve safety and comfort during passage.

[0089] It should be noted that the route calculation module determines whether there is a lowest point near the current slope change point based on the judgment criterion of "the slope of the front slope is negative and the slope of the back slope is positive". If there is, the route calculation module calculates the lowest point information. The route calculation module is a strongly related external module, which mainly implements route-related calculation functions, including but not limited to the conversion between mileage and coordinates, the calculation of the lowest point of the route, and the calculation of the equal division of the route mileage segment.

[0090] In one feasible implementation, step S10 may include steps A11 to A13:

[0091] Step A11: Based on the longitudinal slope information and slope judgment criteria of the double-track tunnel to be designed, point detection is carried out;

[0092] It should be noted that in this embodiment, the slope judgment standard refers to the judgment standard of "the slope of the front slope is negative and the slope of the back slope is positive". The line calculation module performs point detection based on the longitudinal slope information of the line and the slope judgment standard to determine whether there is a lowest point near the current slope change point of the first tunnel line and the second tunnel line respectively.

[0093] Step A12: When there are multiple target points in the first tunnel line and the second tunnel line, determine the mileage and elevation information of each target point in the first tunnel line and the second tunnel line based on the longitudinal slope information of the line.

[0094] It should be noted that, based on the point detection results of the first tunnel line and the second tunnel line, when it is determined that there are multiple target points on the first tunnel line and the second tunnel line respectively, the basic information corresponding to the lowest point is calculated using the line calculation module. That is, the mileage information, elevation information and coordinate information of each target point are obtained through the calculation results.

[0095] Step A13: Determine the basic information of multiple target points corresponding to the first tunnel line and the second tunnel line based on the mileage and elevation information of each target point in the first tunnel line and the second tunnel line.

[0096] It should be noted that by using the mileage, elevation, and coordinate information of each target point on the two tunnel routes, the basic information of multiple target points corresponding to the first and second tunnel routes can be obtained.

[0097] In this embodiment, point detection is performed based on the longitudinal slope information and slope judgment criteria of the double-track tunnel to be designed. When there are multiple target points in the first and second tunnel lines, the mileage and elevation information of each target point in the first and second tunnel lines are determined according to the longitudinal slope information. Based on the mileage and elevation information of each target point in the first and second tunnel lines, the basic information of multiple target points corresponding to the first and second tunnel lines is determined, thereby accurately obtaining multiple target points and their corresponding basic information on the first and second tunnel lines.

[0098] The above is only one possible implementation of step S10 provided in this embodiment. This embodiment does not specifically limit the specific implementation of step S10.

[0099] Step S20: Based on the basic information of multiple target points corresponding to the first tunnel line and the second tunnel line respectively, perform neighboring point matching, and determine multiple initial connecting channels / pump stations and the center mileage information of each initial connecting channel / pump station based on the point matching results.

[0100] It should be noted that multiple target points existing on the first and second tunnel routes are matched one by one using the nearest-neighbor principle based on the basic information of each target point. For example... Figure 2As shown, a connecting passage / pump station can only be set up when the target points of the first tunnel line and the second tunnel line match each other. The lowest point of a one-way match is marked as a point where a connecting passage / pump station cannot be set up. The connecting passage / pump station that can be set up after the initial match and meets the design fire protection requirements are the multiple initial connecting passage / pump stations in the double-track tunnel to be designed. By using the basic information of each target point of the matched first tunnel line, the center mileage information of the initial connecting passage / pump station on the first tunnel line can be determined. By using the basic information of each target point of the matched second tunnel line, the center mileage information of the initial connecting passage / pump station on the second tunnel line can be determined. The center mileage information of the initial connecting passage / pump station on the first tunnel line and the center mileage information of the second tunnel line constitute the center mileage information of the initial connecting tunnel.

[0101] Understandably, before performing neighboring point matching, it is necessary to first determine whether each target point on the first tunnel line is within the tunnel mileage range of the double-track tunnel to be designed, based on the basic information of each target point on the second tunnel line. Then, it is necessary to determine whether each target point on the first tunnel line is within the tunnel mileage range of the double-track tunnel to be designed, based on the basic information of each target point on the second tunnel line, and store the target points on the first and second tunnel lines that are within the tunnel mileage range. Matching is then performed based on the target points on the first and second tunnel lines that are within the tunnel mileage range.

[0102] In one feasible implementation, step S20 may further include steps B11 to B13:

[0103] Step B11: Based on the basic information of multiple target points corresponding to the first tunnel line and the second tunnel line respectively, perform distance calculation to determine the point spacing between each target point on the first tunnel line and each target point on the second tunnel line.

[0104] It should be noted that, based on the basic information of each target point on the first tunnel line and the basic information of each target point on the second tunnel line, the distance between each target point on the first tunnel line and each target point on the second tunnel line is calculated to determine the point spacing between each target point on the first tunnel line and each target point on the second tunnel line.

[0105] Step B12: Based on the principle of proximity, the target points on the first tunnel route and the target points on the second tunnel route are matched with neighboring points to determine the matching results.

[0106] It should be noted that the principle of proximity means that each target point on the first tunnel line finds the nearest target point on the second tunnel line, and at the same time, each target point on the second tunnel line finds the nearest target point on the first tunnel line. A match is successful only when the target points on the first and second tunnel lines are closest to each other; otherwise, the match is considered unsuccessful.

[0107] Step B13: Based on the point matching results and the basic information of multiple target points corresponding to the first tunnel line and the second tunnel line respectively, determine the multiple initial connecting channels / pump houses of the double-track tunnel to be designed and the center mileage information of each initial connecting channel / pump house.

[0108] It should be noted that by matching the target points on the first tunnel route with the target points on the second tunnel route, multiple sets of successfully matched target points are determined. Once the target points on the first tunnel route and the target points on the second tunnel route are successfully matched, the basic information of the two sets of successfully matched target points is associated and saved based on the basic information of the target points. After the basic information of the two sets is associated and saved, the traceability of the matching results can be ensured, and the matching status of the target points can be displayed to facilitate the designers to review and verify.

[0109] It is understandable that the requirements for fire evacuation distances inside the tunnel are being obtained, such as... Figure 3 As shown, multiple sets of target points that have been successfully matched are identified. For each set of target points, it is determined whether a connecting passage / pump station should be set up to meet the drainage requirements. Each set of target points that meets the drainage requirements is deemed suitable for setting up a connecting passage / pump station, thus obtaining the initial connecting passage / pump station in the double-track tunnel to be designed. Based on the basic information of the target points, the center mileage information of the initial connecting passage / pump station on the first tunnel line and the center mileage information of the initial connecting passage / pump station on the second tunnel line are determined. The center mileage information of the initial connecting passage / pump station on the first tunnel line and the center mileage information of the initial connecting passage / pump station on the second tunnel line constitute the center mileage information of the initial connecting tunnel.

[0110] In specific implementations, such as Figure 4As shown, in some cases, such as when the target point of the line is located in the section ventilation shaft, the initial connecting passage / pump room is set by default and automatically set after being identified by the program. In this embodiment, the connecting passage layout scheme mainly needs to meet the fire evacuation distance requirements of relevant specifications. In other application scenarios, the control logic of the connecting passage layout scheme can be adjusted or added to adapt to its business needs. Furthermore, the internal fire evacuation distance can be specified by the designer through manual input, or the control value can be obtained by automatically querying relevant documents to improve the automation level of the program. In this embodiment, the target points of the matched first tunnel line and second tunnel line are set with connecting passage / pump rooms by default. The designer can manually adjust the setting of the connecting passage / pump room by clicking the checkbox to improve design efficiency and obtain multiple initial connecting passage / pump rooms. Furthermore, after confirming the setting of the connecting passage / pump room, the mileage of the lowest point of the left and right lines is used as the center mileage of the left and right lines of the connecting passage / pump room. It should be noted that in the design of long-distance double-track tunnels, the section ventilation shaft is generally set in the middle of the tunnel to meet the tunnel ventilation requirements. In order to reduce the project cost, usually The connecting passage or connecting passage combined with the ventilation shaft is set up. In this embodiment, the boundary mileage between the ventilation shaft and the tunnel is automatically generated by other software modules or manually entered by the designer. By default, the ventilation shaft is set up together with the connecting passage or connecting passage combined with the pump room. Furthermore, in other application scenarios, individual buildings that play a similar role to the ventilation shaft can also be processed according to the above logic. It should be noted that in this embodiment, when the lowest point is located in the ventilation shaft, the connecting passage combined with the pump room is set up in the ventilation shaft by default and cannot be adjusted or canceled. If there is a need to cancel the setting in other business scenarios, an adjustment function can be added without affecting the use of this method.

[0111] The above is only one possible implementation of step S20 provided in this embodiment. This embodiment does not specifically limit the specific implementation of step S20.

[0112] This embodiment calculates the distance between target points on the first and second tunnel lines by performing distance calculations based on the basic information of multiple target points corresponding to the first and second tunnel lines, respectively. Then, based on the principle of proximity, it performs neighboring point matching according to the distances between the target points on the first and second tunnel lines, determining the matching results. Based on the matching results and the basic information of the multiple target points corresponding to the first and second tunnel lines, it determines the center mileage information of multiple initial connecting passages / pump stations and each initial connecting passage / pump station for the dual-track tunnel to be designed. This ensures the accuracy of the matching process and enables rapid determination of the initial connecting passages / pump stations and their corresponding center mileage information, laying the foundation for subsequent deployment schemes.

[0113] Step S30: The first tunnel line is segmented by using the center mileage information of each initial connecting channel and pump room and the boundary mileage information of the tunnel ventilation shaft to obtain multiple evacuation segments of the first tunnel line.

[0114] It should be noted that a tunnel ventilation shaft refers to a pre-existing ventilation shaft within the planned double-track tunnel. The tunnel boundary mileage between the ventilation shaft and the planned double-track tunnel indicates the location of different sections of the planned double-track tunnel. Figure 5 As shown, A is a tunnel ventilation shaft in the double-track tunnel to be designed.

[0115] It is understandable that the evacuation segmentation of the first tunnel line is divided by using the central mileage information of each initial connecting channel and pump house and the boundary mileage information between the tunnel ventilation shaft and the tunnel to be designed, so as to obtain multiple evacuation segments of the first tunnel line and store the mileage range of each evacuation segment.

[0116] Step S40: Determine the number of target passages for each evacuation segment based on the segment spacing and fire evacuation spacing of the multiple evacuation segments of the first tunnel line.

[0117] It should be noted that the fire evacuation distance refers to the pre-set fire evacuation distance inside the tunnel. The distance between each evacuation segment is obtained by the mileage range of each evacuation segment, representing the length of each evacuation segment. The distance between each evacuation segment is divided by the fire evacuation distance, and the result is rounded up. This number is the number of connecting passages that need to be added to meet the fire evacuation distance requirement for that evacuation segment. The number of connecting passages that need to be added to meet the fire evacuation distance requirement for that evacuation segment is the target number of passages for each evacuation segment.

[0118] Understandably, in this embodiment, the computer obtains the center mileage of the first tunnel line, which is confirmed by the designer to require N connecting passages / pump rooms. The first tunnel line is then divided into N+1 evacuation segments. Each evacuation segment should have sufficient connecting passages to meet fire evacuation distance requirements. Furthermore, if a ventilation shaft exists within an evacuation segment, a connecting passage is defaulted to be set within the ventilation shaft. The current evacuation segment is then divided into two independent evacuation segments according to the boundary mileage between the ventilation shaft and the tunnel. Furthermore, in other application scenarios, individual buildings that serve a similar function to ventilation shafts can also be processed according to the above logic. It should be noted that in this embodiment, connecting passages / pump rooms are defaulted to being set in the tunnel ventilation shaft and cannot be adjusted or canceled. If other business scenarios require cancellation, an adjustment function can be added without affecting the use of this method. Furthermore, the length of each evacuation segment is divided by the calculated fire evacuation distance and rounded up to obtain the number of connecting passages for that evacuation segment, ensuring that the spacing between evacuation passages meets the fire evacuation distance requirements under uniform distribution. It should be noted that the number of connecting passages for each evacuation segment should be stored in the computer memory for subsequent steps to read or adjust.

[0119] Step S50: Determine multiple target connecting channels and the center mileage information of each target connecting channel based on the number of target channels in each evacuation segment and the center mileage information of each initial connecting channel / pump station.

[0120] It should be noted that a target number of connecting channels are added to each evacuation segment. The connecting channels are added in each evacuation segment in a equidistant manner. By combining the added connecting channels and their corresponding center mileage information with the initial connecting channel / pump station and its corresponding center mileage information, multiple target connecting channels and their corresponding center mileage information are obtained.

[0121] Step S60: Determine the design scheme of the connecting passage for the dual-track tunnel to be designed based on the center mileage information of each target connecting passage.

[0122] It should be noted that, taking into account the surrounding environment and geological conditions, the center mileage information of each target connecting passage was adjusted, and the final connecting passage design scheme was determined based on the adjustment results. Figure 6 As shown.

[0123] In one feasible implementation, step S60 may include steps C11 to C15:

[0124] Step C11: Obtain the surrounding environment information of each target communication channel;

[0125] It should be noted that the surrounding environment information includes, but is not limited to, the surrounding environment information and geological information of the dual-track tunnel to be designed.

[0126] Step C12: Evaluate the design location of each target communication channel based on the surrounding environmental information of each target communication channel;

[0127] It should be noted that the design location of each target communication channel can be determined by the center mileage information of each target communication channel. The design location of each target communication channel is evaluated based on the surrounding environmental information of the target communication channel to determine whether the design location is suitable for designing the target communication channel.

[0128] Step C13: When the evaluation results of each target connecting passage are the preset qualified results, determine the preliminary design scheme of the double-track tunnel to be designed based on the center mileage information of each target connecting passage.

[0129] It should be noted that when the design location of each target connecting passage can be designed as a connecting passage and pump room, it means that the evaluation result of each target connecting passage is a pre-set qualified result. At this time, the preliminary design scheme of the double-track tunnel to be designed is determined based on the center mileage information of each target connecting passage.

[0130] Step C14: Analyze the preliminary design scheme according to the scheme evaluation principles;

[0131] It should be noted that, since the design of the connecting passage and pumping station needs to meet the requirements of project cost, drainage of the interval, and other professional aspects, it is necessary to obtain the scheme evaluation principles. The scheme evaluation principles include, but are not limited to, the design requirements of project cost and drainage of the interval. The preliminary design scheme is analyzed through the scheme evaluation principles to determine whether the preliminary design scheme meets the scheme evaluation principles.

[0132] Step C15: When the scheme analysis result is a preset reasonable result, determine the design scheme of the connecting passage of the double-track tunnel to be designed according to the preliminary design scheme.

[0133] It should be noted that when the preliminary design scheme meets the scheme evaluation principles, it means that the scheme analysis results are the pre-set reasonable results. In this case, the preliminary design scheme will be used as the design scheme for the connecting passage of the double-track tunnel to be designed.

[0134] Understandably, based on the surrounding environment and geological conditions of the tunnel, designers interactively adjust the mileage of each target connecting passage. During this interactive adjustment process, the adjusted connecting passage will fix its left and right line mileage and serve the same function as the connecting passage / pump station for evacuation segmentation. Repeating the steps of tunnel segmentation and adding connecting passages, the connecting passage layout plan needs to be continuously updated. Finally, the final connecting passage layout plan is determined through continuous interactive updates. Figure 6As shown. In this embodiment, the civil engineering related to the geological survey is loaded into the CAD platform in the form of a base map. The computer draws and displays the layout scheme of the target connecting channel calculated after adding the connecting channel. Designers decide whether to adjust the connecting channel by viewing the surrounding environment and geological conditions. Furthermore, the adjustment of the connecting channel is carried out by mouse interaction or by manually inputting the right line mileage to determine the appropriate right line mileage position. Then, after determining the position of adding the connecting channel in the right line, a perpendicular line is drawn to the left line to calculate the mileage of the left line. Furthermore, after determining that the current connecting channel adjustment is completed, the selected option can be checked. The method involves fixing the current connecting passage at a certain mileage position and recording the fixed connecting passage. It should be noted that connecting passages can be fixed or opened, and can be adjusted interactively by designers until all connecting passage positions are fixed, resulting in the final connecting passage layout plan. In this embodiment, each time the mileage position of the connecting passage is fixed, the evacuation segmentation of the right tunnel is performed using the mileage of the connecting passage that also serves as the pump room center, the boundary mileage between the ventilation shaft and the tunnel, and the mileage of the fixed connecting passage center. The process of tunnel segmentation and adding connecting passages is repeated. It should be noted that the plan is refreshed after the connecting passage is fixed to ensure that the current plan always meets the requirements for fire evacuation distance.

[0135] In practical implementation, since all business information related to the design of connecting passages has been stored, the computer systematically analyzes the scheme data using built-in evaluation principles for the final connecting passage layout scheme. It provides rationalization suggestions from professional perspectives such as engineering cost and drainage, for designers' reference. In this embodiment, based on the current tunnel design information and the connecting passage layout scheme information, the sum of the distances between each connecting passage and the connecting passages on both sides is calculated and compared with the fire evacuation distance to evaluate the rationality of the scheme. The main recommended measures are to adjust the location of the line, stations, and ventilation shafts to minimize the number of connecting passages in each section. Figure 7 As shown; furthermore, in other business scenarios, there are different evaluation criteria. Similarly, the computer can execute the corresponding evaluation principles, analyze the current solution information, and provide reasonable suggestions to optimize the design results.

[0136] This embodiment acquires the surrounding environmental information of each target connecting passage; evaluates the design location of each target connecting passage based on the surrounding environmental information; when the evaluation result of each target connecting passage is a preset qualified result, determines the preliminary design scheme of the double-track tunnel to be designed based on the center mileage information of each target connecting passage; analyzes the preliminary design scheme according to the scheme evaluation principle; when the scheme analysis result is a preset reasonable result, determines the connecting passage design scheme of the double-track tunnel to be designed based on the preliminary design scheme. Through the above methods, the design results are optimized and the design quality is improved.

[0137] This embodiment provides a method for designing connecting passages for a dual-track tunnel. The method involves determining basic information about multiple target points corresponding to the first and second tunnel lines based on the longitudinal slope information of the tunnel to be designed; performing neighboring point matching based on the basic information of the multiple target points corresponding to the first and second tunnel lines; determining multiple initial connecting passages / pump houses and their center mileage information based on the matching results; segmenting the first tunnel line using the center mileage information of each initial connecting passage / pump house and the boundary mileage information of the tunnel ventilation shaft to obtain multiple evacuation segments; determining the number of target passages in each evacuation segment based on the segment spacing and fire evacuation spacing; determining multiple target connecting passages and their center mileage information based on the number of target passages in each evacuation segment and the center mileage information of each initial connecting passage / pump house; and finally, determining the connecting passage design scheme for the dual-track tunnel to be designed based on the center mileage information of each target connecting passage. The above methods enable the batch and automation of communication channel layout design, significantly improving design efficiency and reducing error rate, eliminating the traditional manual drawing design method, and greatly reducing labor and time consumption.

[0138] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 8 Before step S20, the design method for the connecting passage of the dual-track tunnel further includes steps S21 to S25:

[0139] Step S21: Obtain the coordinates of the intersection point between the centerline of the double-track tunnel to be designed and the outline of the working shaft;

[0140] It should be noted that within the CAD platform of the equipment for designing connecting passages in double-track tunnels, the coordinates of the intersection points of the centerline of the double-track tunnel to be designed and the outline of the tunnel end working shaft are automatically calculated. The centerline and the outline of the tunnel end working shaft are stored as coordinate arrays and drawn as lines within the CAD system, such as... Figure 9 As shown.

[0141] It is understood that in this embodiment, the contour data of the line centerline and the tunnel end working well are manually input by the designer or automatically generated by other software modules, and the contour data can be read into the computer memory and saved to the local database file; furthermore, the CAD platform reads the contour data of the line centerline and the tunnel end working well and draws the lines of the two, and obtains the intersection point of the line centerline and the tunnel end working well through the CAD platform, or the designer manually confirms the intersection point.

[0142] Step S22: Determine the tunnel mileage information of the double-track tunnel to be designed based on the coordinates of the intersection of the centerline of the line and the outline of the working shaft;

[0143] It should be noted that the coordinates of the intersection of the centerline of the line and the outline of the working shaft are input into the line calculation module. The line calculation module converts the intersection into mileage, and the resulting mileage is the starting mileage and ending mileage of the designed double-track tunnel. The starting mileage and ending mileage of the double-track tunnel to be designed constitute the tunnel mileage information of the double-track tunnel to be designed.

[0144] Step S23: Determine the tunnel mileage range of the double-track tunnel to be designed based on the tunnel mileage information;

[0145] Step S24: Detection is performed based on the basic information of multiple target points corresponding to the first tunnel line and the second tunnel line, and the tunnel mileage range;

[0146] It should be noted that the tunnel mileage range of the double-track tunnel to be designed can be obtained through the tunnel mileage information. Based on the basic information of each target point on the first tunnel line and the second tunnel line, it is determined whether the target points on the first tunnel line and the second tunnel line are located within the tunnel mileage range.

[0147] Step S25: When multiple target points corresponding to the first tunnel line and the second tunnel line are within the tunnel mileage range of the double-track tunnel to be designed, perform a step of matching neighboring points based on the basic information of the multiple target points corresponding to the first tunnel line and the second tunnel line.

[0148] It should be noted that the target points on the first tunnel line and the second tunnel line located within the tunnel mileage range are stored, and matching is performed based on the target points on the first tunnel line and the second tunnel line located within the tunnel mileage range.

[0149] It is understandable that in this embodiment, the focus is mainly on the lowest point within the tunnel mileage range of the dual-track tunnel to be designed. The lowest point is selected by the tunnel's starting and ending mileages. In other application scenarios, the selection logic for the lowest point can be adjusted to meet their business needs.

[0150] This embodiment provides a method for designing connecting passages for a double-track tunnel. The method involves obtaining the coordinates of the intersection of the centerline of the double-track tunnel to be designed and the outline of the working shaft; determining the tunnel mileage information of the double-track tunnel based on the intersection coordinates; determining the tunnel mileage range of the double-track tunnel based on the tunnel mileage information; detecting multiple target points corresponding to the first and second tunnel lines based on the tunnel mileage range; and performing a neighboring point matching step based on the basic information of the multiple target points corresponding to the first and second tunnel lines when the multiple target points are within the tunnel mileage range of the double-track tunnel to be designed. This ensures the rationality and accuracy of the subsequent layout of the connecting passage.

[0151] Based on the first and / or second embodiments of this application, in the third embodiment of this application, the content that is the same as or similar to that in embodiments one and two above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 10 Step S50, the design method for the connecting passage of the dual-track tunnel further includes steps S51 to S53:

[0152] Step S51: Divide the first tunnel line into tunnels according to the number of target channels in each evacuation segment, and obtain the division points of each evacuation segment.

[0153] It should be noted that, based on the principle of equal spacing, each evacuation passage of the first tunnel line is divided according to the target number of passages in each evacuation segment, and the division points of each evacuation segment are obtained. Each division point is the location of the connecting passage to be added on the first tunnel line.

[0154] Step S52: Determine the additional connecting passages and the center mileage information of each additional connecting passage for each evacuation segment on the first tunnel line based on the segmentation information of each evacuation segment and the division point of each evacuation segment.

[0155] It should be noted that in this embodiment, the batch deployment of internal connecting channels in each evacuation section of the right-line tunnel is completed sequentially by adopting the principle of equal spacing. This is achieved by reading the number M of connecting channels that should be deployed in the current evacuation section from the computer memory, and using the line calculation module to calculate the coordinates of the M+1 equal division points of the current evacuation section mileage range and their corresponding right-line mileage.

[0156] In one feasible implementation, step S52 may include steps D11 to D14:

[0157] Step D11: Draw perpendicular lines from the division points of each evacuation section and the channel connection principle to obtain the line perpendicular lines of each division point.

[0158] It should be noted that the channel connection principle refers to, after determining the location of the connecting channel to be added in each evacuation segment on the first tunnel line, in this embodiment, connecting the first tunnel line and the second tunnel line by drawing a vertical line from the division point.

[0159] Understandably, for each evacuation segment, based on the coordinates of the division points on the first tunnel line, the perpendicular line of the left line is drawn from the aforementioned coordinates, thereby obtaining the perpendicular line of the line corresponding to each division point.

[0160] Step D12: Determine the matching channel point on the second tunnel line for each division point based on the intersection of the perpendicular line of each division point and the second tunnel line.

[0161] It should be noted that the intersection of the perpendicular line of each dividing point with the second tunnel line is determined, and this intersection is used as the matching channel point corresponding to the dividing point on the second tunnel line.

[0162] Step D13: Based on the matching channel locations of each division point on the second tunnel line and the segmentation information of each evacuation segment, determine multiple additional connecting channels, and the first and second center mileages of each additional connecting channel.

[0163] It should be noted that the designated points are the locations of the connecting passages that need to be added to each evacuation segment on the first tunnel line. The matching passage points on the second tunnel line based on each designated point are the locations of the passages on the second tunnel line. Thus, based on the locations of the connecting passages that need to be added to each evacuation segment on the first tunnel line and the second tunnel line, multiple connecting passages that need to be added to each evacuation segment are obtained. These multiple connecting passages that need to be added to each evacuation segment are the multiple additional connecting passages.

[0164] It is understandable that the segment information of each evacuation segment refers to the mileage information of each evacuation segment. The line calculation module determines the center mileage information of the connecting channel that needs to be added in each evacuation segment on the first tunnel line by using the mileage information of each evacuation segment and the division points in each evacuation segment. The center mileage information of the added connecting channel of each evacuation segment on the first tunnel line is the first center mileage of each added connecting channel.

[0165] In the specific implementation, the second center mileage of the matching channel point on the second tunnel line is calculated by the line calculation module. The second center mileage is the center mileage information of the added connecting channel on the second tunnel line.

[0166] Step D14: Summarize the first and second center mileages of each added communication channel to obtain the center mileage information of each added communication channel.

[0167] It should be noted that the first and second center mileages of each added communication channel together constitute the center mileage information of each added communication channel.

[0168] Step S53: Determine multiple target communication channels and their center mileage information based on the center mileage information of each added communication channel and each initial communication channel / pump station.

[0169] It should be noted that after determining the center mileage information of each added connecting passage, the distance between connecting passages on the second tunnel line is calculated and checked one by one from the starting mileage of the second tunnel line towards the greater mileage direction to see if it meets the fire evacuation distance requirement. Furthermore, if the distance between a certain connecting passage and the connecting passages on both sides is greater than the fire evacuation distance value, the number of connecting passages in the evacuation section where the connecting passage is located should be increased by 1, and the above calculation process of adding connecting passages for the vertical line should be repeated for this evacuation section. Furthermore, during the second tunnel line verification process, connecting passages that also serve as pump rooms and ventilation shafts are all verified as connecting passages. When calculating the distance between connecting passages for ventilation shafts, the boundary mileage between the ventilation shaft and the tunnel is used as the calculation mileage. It should be noted that if a double-track tunnel fails the second tunnel line verification, the number of connecting passages in the evacuation section should be increased by 1. If the verification fails again, it means that the tunnel cannot meet the fire evacuation requirements by setting up connecting passages, and the designers should be advised to add ventilation shafts or other structures that can play a role in evacuation.

[0170] Understandably, after detecting that the distance between connecting passages on the second tunnel line meets the fire evacuation distance, the center mileage information of the added connecting passages and the center mileage information of each initial connecting passage that also serves as a pump room will be summarized to determine multiple target connecting passages and the center mileage information of each target connecting passage.

[0171] In the specific implementation, the principle of equal spacing is adopted to complete the layout of internal connecting passages in each evacuation segment in batches on the right line. The mileage of the left line is obtained by using the mileage of the right line as a perpendicular line. The computer calculates the center mileage of the left and right lines of all connecting passages in each evacuation segment in batches, and checks whether the distance between each connecting passage on the left line and the distance between the connecting passage and the start and end points of the tunnel meet the fire evacuation distance requirements. If the check fails, a connecting passage is added to the evacuation segment, and the check is performed again to obtain the added connecting passage. Combined with the initial connecting passage that also serves as a pump room, the target connecting passage in the double-line tunnel to be designed is obtained, and the center mileage information of the target connecting passage is determined.

[0172] This embodiment provides a method for designing connecting passages for a double-track tunnel. The method involves drawing perpendicular lines from the division points of each evacuation segment and the passage connection principles to obtain the perpendicular lines of each division point. The method then determines the matching passage points on the second tunnel line for each division point based on the intersections of these perpendicular lines and the second tunnel line. Based on the matching passage points on the second tunnel line and the segmentation information of each evacuation segment, multiple additional connecting passages are determined, along with the first and second center mileages of each additional connecting passage. Finally, the first and second center mileages of each additional connecting passage are summarized to obtain the center mileage information for each additional connecting passage.

[0173] For example, to help understand the implementation process of the dual-track tunnel connection channel design method obtained by combining Embodiment 1 and Embodiment 2 above, please refer to... Figure 11 , Figure 11 A simplified schematic diagram of a design method for a connecting passage in a two-track tunnel is provided, specifically:

[0174] The design method for the connecting passage of the double-track tunnel in this embodiment includes the following steps: Step 1: In the CAD platform, the computer automatically solves the coordinates of the intersection point between the centerline of the line and the outline of the working well at the end of the tunnel, and inputs them into the line mileage calculation module to obtain the starting and ending mileage of the tunnel.

[0175] Step 2: Import the longitudinal slope information table of the line. Using "the slope of the front slope is negative and the slope of the back slope is positive" as the judgment standard, the computer batch judges whether there is a lowest point at the longitudinal slope change point of the left and right lines, calculates and saves the mileage and elevation information of the lowest point of the left / right line.

[0176] Step 3: Determine whether each lowest point of the left / right line is within the tunnel mileage range, store the lowest points of the line within the tunnel range, and match them one by one according to the nearest principle. The lowest points that are not matched are marked as not being able to set up a connecting passage and pump room.

[0177] Step 4: The designer inputs the fire evacuation distance requirements inside the tunnel, and specifies whether a connecting passage / pump house should be set up between the lowest points of each pair of double lines to meet the drainage requirements, and saves the center mileage of the left and right lines of the connecting passage / pump house.

[0178] Step 5: Use the mileage of the connecting passage and pump room center, and the boundary mileage between the ventilation shaft and the tunnel to divide the right tunnel into evacuation sections. Determine the number of connecting passages that need to be added to meet the fire evacuation distance for each section based on the length of each evacuation section. Store the mileage range of each evacuation section and the number of connecting passages that need to be added.

[0179] Step 6: The computer uses the principle of equal spacing to complete the layout of internal connecting passages in each evacuation section in batches, and checks whether the distance between each connecting passage on the left line and between the connecting passage and the beginning and end of the tunnel meet the fire evacuation distance requirements. If the check fails, an additional connecting passage is added to the evacuation section, and the check is performed again.

[0180] Step 7: Based on the surrounding environment and geological conditions of the tunnel, the designers interactively adjust the mileage of the connecting passages one by one. During the interactive adjustment process, the layout plan of the connecting passages needs to be constantly updated. The adjusted connecting passages will have fixed mileage positions and play the same role as the connecting passages and pump rooms in evacuation segmentation. Repeat steps 5 to 6, and finally determine the final layout plan of the connecting passages through continuous interactive updates.

[0181] Step 8: For the final connection channel layout plan, the computer analyzes the plan data and provides rationalization suggestions from common professional perspectives such as engineering cost and drainage of the section for the designers' reference.

[0182] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the design method of the connecting passage of the double-track tunnel in this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0183] This application also provides a design device for a connecting passage in a dual-track tunnel, please refer to... Figure 12 The connecting passage design device for the dual-track tunnel includes:
