[0002] As the demand for intensive urban development intensifies, the importance of horizontal pipeline corridors, as the core vehicle for the intensive utilization of underground space, is becoming increasingly prominent. As the "lifeline" of urban infrastructure, horizontal pipeline corridors can effectively alleviate land shortages in urban centers by integrating various municipal pipelines. Pipeline corridor design requires comprehensive consideration of the coordinated layout of up to 12 specialized pipeline types, including water supply and drainage, electricity, communications, and gas. These pipelines are numerous in type and route. Therefore, it is necessary to rationally arrange and route the various pipelines in the horizontal pipeline corridor to achieve functional and regulatory requirements while saving costs.

[0003] However, in existing layouts, pipelines are often placed above, below, or to the sides of corridors, severely restricting access for maintenance personnel. Especially in narrow corridors with complex equipment, pipeline layouts often result in low space utilization and insufficient maintenance space. Summary of the Invention

[0009] Furthermore, S3 also includes: S4: performing maintenance accessibility simulation on the optimal arrangement scheme in combination with a human body model to verify maintenance blind spots and blocking factors, thereby finding problem areas in the optimal arrangement scheme, and fine-tuning and optimizing the problem areas to obtain a target arrangement scheme.

[0010] Furthermore, after S4, the step also includes: presenting the target layout plan in the form of drawings and parameter files, construction drawings, cross-section drawings and construction guidance documents for real-time adjustment and updating during on-site construction.

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0026] Example 1 This embodiment provides a pipeline layout design method for a horizontal pipe gallery, such as Figure 1 As shown, the following steps are included.

[0027] S1: Based on the design principles of locating the air duct area at the top of the horizontal corridor, the maintenance space in the middle with an unobstructed bottom, and the water pipe area below the high-voltage and low-voltage areas, various pipeline layout patterns are developed for the horizontal corridor based on the actual dimensions, pipeline types, and quantity. It is important to note that prior to S1, detailed information on each specialized pipeline can be collected, including pipeline type (such as water pipes, gas pipes, cables, ventilation ducts, etc.), quantity, diameter, length, material, minimum allowable bend radius, and connector dimensions. The actual dimensions of each pipeline will influence its placement within the corridor and the required clearances. By obtaining actual corridor dimensions, such as corridor width, height, wall location, overhead beam position, and other structural obstacles, it is possible to determine the area available for pipeline layout and clarify restrictions (such as beam bottoms, ceiling height, and floor-level equipment).

[0028] Specifically, the corridor space is abstracted into a preset space. The core features of the preset space are: the air duct area is located at the top of the horizontal pipe corridor, the maintenance space is located in the middle and has no obstruction at the bottom, and the water pipe area is located at the lower end of the high-voltage area and the low-voltage area. According to the actual horizontal pipe corridor width, clear height, number and type of pipelines, multiple possible pipeline layout modes are set. Among them, the various pipeline layout modes include but are not limited to horizontal arrangement, staggered arrangement, layered arrangement and other combinations of pipelines. Each pipeline layout mode is designed to ensure that the maintenance space runs through the cross section of the corridor, forming an obvious preset layout, so that the pipelines and maintenance areas do not interfere with each other.

[0029] S2: Based on spatial constraints, the specific location and arrangement order of pipelines in each area of ​​each pipeline layout mode are systematically designed to obtain a three-dimensional pipeline layout model corresponding to each pipeline layout mode.

[0030] Specifically, based on the actual dimensions of the horizontal utility corridor, pipeline types, and quantity, the area available for pipeline layout is determined, and restrictions (such as beam bottoms, ceiling heights, and ground equipment) are clearly defined. For each pipeline layout pattern, a systematic design of maintenance space, pipeline location, and arrangement sequence is conducted to ensure the rational layout of different pipelines and accessibility of maintenance operations.

[0031] As an optional implementation, S2 includes: considering the layout area and space constraints, inputting the professional pipeline design parameters corresponding to each pipeline layout mode and the actual structural characteristics of the corridor into the selected layout algorithm, and constructing a three-dimensional pipeline layout model corresponding to each pipeline layout mode. For example, a three-dimensional pipeline layout model of each pipeline layout mode can be constructed using Revit, such as Figure 2 During the modeling process, a set of rules can also be set to set the priority of pipeline layout and determine the arrangement order of each pipeline to minimize crossing, overlapping or repeated detours.

[0032] As an optional implementation, the specialized pipeline design parameters corresponding to each pipeline layout pattern and the actual structural characteristics of the corridor are input into a lowest level line algorithm, which is designed according to optimization principles, ultimately generating a three-dimensional pipeline arrangement model corresponding to each pipeline layout pattern. The optimization principles include: arranging pipelines sequentially from top to bottom, optimizing the total height occupied by pipelines, prioritizing large or installation-critical pipelines, and arranging small pipelines in rows. The specialized pipeline design parameters include at least pipeline size, material, connector specifications, and allowable bend radius.

[0033] To maximize the corridor clear height, the lowest horizontal line algorithm is used to highly optimize the 3D pipeline layout model under each pipeline layout mode. The specific steps include: (1) Perform height statistics on the three-dimensional pipeline layout model under each layout mode and calculate the net height occupied by each pipeline in the corridor cross section; the pipeline layout is completed as follows: Figure 3 shown.

[0034] (2) Based on the layout height of each pipeline, calculate the overall vertical space occupancy and use the lowest horizontal line algorithm to arrange the pipeline positions to minimize the layout height occupancy. Prioritize the layout of pipelines with larger sizes or strict installation requirements (such as ventilation ducts and gas pipelines), and then gradually arrange pipelines with smaller diameters. By optimizing the layout order, reduce the mutual interference between pipelines and improve the compactness of the overall layout. For pipelines of the same type (such as multiple cables or multiple small-diameter water pipes), arrange them in rows as much as possible to make full use of the horizontal space and simplify future maintenance and management. The spacing between pipelines arranged in rows is set to the minimum safe distance to avoid soft collisions or operational interference. In each round of optimization, the relative height of each pipeline is detected. If it is found that the layout position of a pipeline affects the overall height (for example, the height of a pipeline is too low, making it impossible for other pipelines to be arranged more compactly), the pipeline is fine-tuned or relocated to release more vertical space.

[0035] (3) Calculate the height occupancy data of each pipeline layout mode and conduct comparative analysis. The comparison indicators include total height occupancy, minimum clear height, layout uniformity, etc. Through data comparison, identify the layout mode with the highest vertical space utilization.

[0036] S3: Compare and analyze the space utilization indicators of the three-dimensional pipeline arrangement models corresponding to each pipeline layout mode to find the optimal arrangement solution.

[0037] As an optional implementation method, the space utilization index includes: clear height distribution and uniformity variance; S3 includes: performing comparative analysis on the space utilization index of the three-dimensional pipeline arrangement model corresponding to each pipeline layout mode, and selecting the scheme with the highest weighted score of the height occupancy corresponding to the clear height distribution and the maintenance convenience corresponding to the uniformity variance as the optimal arrangement scheme.

[0038] Among them, the uniformity of different three-dimensional pipeline layout models is analyzed by uniformity variance calculation. The specific calculation steps include: Area division: Divide the cross section of the pipeline corridor into several functional areas (such as the left pipeline area, the right pipeline area, the middle maintenance space, etc.).

[0039] Regional coverage analysis: Analyze the accessibility and operation frequency of the human body model in each region and calculate the operation coverage area of ​​each region.

[0040] Variance calculation: By comparing the operational coverage area of ​​each area, the uniformity variance is calculated. The smaller the variance, the more balanced the operational convenience and space utilization of each area, and the better the layout.

[0041] Coverage density analysis: Evaluate the activity density of human models in each functional area under each layout mode, that is, whether the areas with frequent operations are consistent with the maintenance space. Density analysis helps to identify which areas are too dense or loose, thus guiding subsequent optimization adjustments such as Figure 5 shown.

[0042] Furthermore, S3 also includes: S4: combining the human body model to simulate the maintenance accessibility of the optimal layout plan to verify the maintenance blind spots and blocking factors, so as to find the problem areas in the optimal layout plan, and fine-tune and optimize the problem areas to obtain the target layout plan.

[0043] To ensure the feasibility of the pipeline layout and the convenience of maintenance, a simulation verification is performed in conjunction with a human body model. The specific operations are as follows: (1) Human accessibility verification: areas that can be reached by the simulated human arm, such as Figure 4 As shown, by simulating the arm movement of the maintenance personnel, the accessible areas within the maintenance space are analyzed. The movable angles of the model's shoulder joint, elbow joint, and wrist are used to gradually verify the maximum movable range of each joint in the space. Detect whether there are blind spots in maintenance and ensure that all key pipelines, valves, connectors, etc. are within the operable range. Through the human model's line of sight and arm extension simulation, areas that may hinder maintenance operations are identified. If certain pipelines or support structures are found to cause obvious obstruction to the maintenance space, they are marked as parts that need to be optimized. Further eliminate or reduce obstruction factors by adjusting the pipeline height, position, or support structure design.

[0044] (2) Multiple scenario testing: The layout plan is tested in a simulated environment under multiple scenarios, including equipment maintenance, pipeline maintenance, emergency operations, etc., to ensure that the plan can adapt to actual project needs.

[0045] As an optional implementation method, S4 also includes: presenting the target layout plan in the form of drawings and parameter files, construction drawings, cross-section drawings and construction guidance documents for real-time adjustment and updating during on-site construction.

[0046] The generation and application of the target layout plan is a key step in this invention. By integrating optimization algorithms, verification results, and user interaction, a seamless transition from design to actual application is achieved. The resulting layout plan is not only used for the output of design drawings, but also for the entire process of construction guidance and post-maintenance. The specific steps are as follows: (1) Integrated optimization results: Combining the optimization results of multiple modules such as pipeline height optimization, human body model verification, and uniformity analysis, the system automatically selects the optimal layout solution that meets various standards. The evaluation results of each layout solution will be scored, including multiple dimensions such as height occupancy, maintenance convenience, uniformity variance, and blocking factors. The solution with the highest score will be marked as the optimal solution. After determining the optimal solution, further refinement and adjustment will be made to the solution, especially for some minor spatial conflicts or areas with inconvenient maintenance. By making local adjustments to the position of key pipelines or fine-tuning the maintenance space, the final solution is ensured to perfectly meet the project requirements. In the process of generating the optimal solution, users are allowed to select multiple high-scoring solutions for parallel comparison. Users can also use the interactive comparison interface to view the advantages and disadvantages of each solution and make the final decision based on specific needs. For example, some solutions may have the best height occupancy but are slightly insufficient in maintenance accessibility, which can be further optimized through manual adjustment.

[0047] (2) 3D model output: The target layout plan is output in the 3D design software (Revit). Through the dynamic display of the 3D model, the layout position of each pipeline, the connectivity of the maintenance space and the installation position of the supporting structure can be fully viewed. Users can view the details of the layout, especially the areas prone to problems, by rotating, zooming in and out of the model. Using the conflict detection function in the design software, the optimal solution is fully tested to check whether there are collisions or interferences between pipelines, between pipelines and supporting structures, and between pipelines and building structures. For the detected conflict points, the system will automatically mark and provide improvement suggestions to ensure that the final layout is conflict-free.

[0048] (3) User interactive adjustment: During the display of the layout plan, a user-friendly interactive interface is provided, through which users can adjust key parameters such as the position of pipelines, the size of the maintenance space, and the angle of the support structure. The interactive interface should have simple and easy-to-use operating instructions, such as dragging, rotating, and zooming, so that users can quickly adjust the layout details. Each time the user adjusts the layout plan, the system will perform optimization calculations in real time and provide feedback on the adjusted results. The adjustment feedback includes the new height occupancy, maintenance accessibility score, uniformity analysis, etc., so that users can immediately understand the adjustment effect during the adjustment process and ensure that each adjustment is in the optimal direction. The system automatically selects the optimal layout plan and makes detailed adjustments through three-dimensional visualization and user interactive interface.

[0049] (4) Data output and construction support: The final optimized pipeline layout plan is output as standard construction drawings and data files, including the detailed size, location, direction and maintenance space configuration of each pipeline, to support on-site construction and engineering applications. In actual engineering applications, it can significantly improve the space utilization of corridors, optimize the rationality of pipeline layout, and ensure the accessibility of maintenance space. The innovative design of the preset layout solves many defects of traditional layout methods, significantly improves the relationship between pipelines and maintenance operations, and makes pipeline layout in complex building environments more efficient, safe and easy to maintain.

[0050] After completing the optimization and comprehensive analysis, this embodiment provides the target arrangement plan in a standardized output format to guide on-site construction and subsequent maintenance work.

[0051] (1) Drawing and data output: Generate detailed layout drawings including plan, section, and 3D views, along with annotations of pipeline dimensions, locations, and access spaces. Output data files support multiple formats (e.g., DWG, PDF, Excel, etc.) for direct use by construction units.

[0052] (2) Construction Instruction Manual: Based on the final optimization plan, a construction instruction manual is generated, detailing the pipeline installation sequence, precautions, and maintenance space requirements. The manual covers pipeline layout standards, construction steps, installation tools, and testing methods to ensure that the construction process proceeds smoothly according to design requirements.

[0053] (3) Maintenance recommendations: Provide recommendations for pipeline maintenance and overhaul, including solutions to common problems, selection of overhaul tools and operating procedures, etc., to facilitate subsequent equipment maintenance and emergency overhaul.

[0054] (4) Real-time construction adjustment support: During the construction process, if the on-site conditions change (such as the actual size does not match the design, temporary equipment adjustment, etc.), the system of the present invention supports real-time on-site adjustments and automatically updates the drawings and construction instructions to ensure that the construction can flexibly respond to various changes.

[0055] Example 2 This embodiment provides a pipeline layout design method for a horizontal pipeline corridor, including: when the horizontal pipeline corridor is a plurality of continuous pipeline corridors, executing the pipeline layout design method for the horizontal pipeline corridor in Example 1 for each continuous pipeline corridor to obtain an optimal layout scheme corresponding to the continuous pipeline corridor; automatically adjusting the longitudinal slope and pipeline layout method in the corner area between two adjacent continuous pipeline corridors to connect the optimal layout schemes corresponding to the various continuous pipeline corridors to obtain an optimal layout scheme corresponding to the entire horizontal pipeline corridor.

[0056] Taking into account the multiple cross-sections in actual projects, the overall layout plan is further optimized by comprehensively analyzing the layout effects of each cross-section. The specific steps are as follows: (1) Multi-cross-section data collection: Collect multiple sets of corridor cross-section data, including pipeline layout at different locations and heights, to ensure that the optimization process takes into account the integrity and continuity of the corridor.

[0057] (2) Cross-section optimization: Comprehensively analyze the continuity and height changes of the pipeline between different cross-sections to ensure the longitudinal continuity and rationality of the pipeline. For sudden changes in pipeline direction or large changes in vertical height, appropriate transition design is carried out to avoid layout incoherence.

[0058] (3) Longitudinal slope and corner considerations: For corridors with longitudinal slopes or corners, the optimization algorithm automatically adjusts the layout of pipelines to avoid overlap or interference at steep slopes or corners. By adjusting the shape and location of the maintenance space, pipelines in special locations can be ensured to remain accessible and operable.

[0059] (4) Unified coordination and adjustment: The optimization results of each cross section are unified and coordinated to generate an overall layout plan. For conflict points between different cross sections, local fine-tuning and height adjustment are used to correct them to ensure the coordination of the overall plan.

[0060] Example 3 This embodiment provides a pipeline layout design device for a horizontal pipeline corridor, including a memory and a processor. The memory stores a computer program, and when the processor executes the computer program, the steps of the pipeline layout design method for the horizontal pipeline corridor in Example 1 are implemented.

[0061] Example 4 This embodiment provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of the pipeline layout design method for the horizontal pipeline corridor in Example 1 are implemented.

[0062] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
