[0068] The track state change data reflects the current condition and future change trend of the railway track, and the track state change data includes:

[0069] Track geometric dimensions: Measure geometric dimensions such as gauge, level, alignment, and cross-level of the track to ensure good docking with the track after the bridge is erected and guarantee the smooth passage of construction equipment;

[0070] Track material and wear condition: Understand the material and wear degree of the track, evaluate the bearing capacity and stability of the track, and provide a basis for bridge design;

[0071] Track maintenance records: Consult the maintenance history of the track to understand recent maintenance projects, maintenance times, and maintenance effects, so as to conduct necessary inspections and adjustments on the track before the bridge is erected;

[0072] The operation line operation data reflects the actual situation and future plans of railway operation. The operation line operation data includes:

[0073] Train operation diagram: Obtain the train operation plan for the current and a period of time in the future, understand information such as the departure time, arrival time, running speed, and train number of the train, so as to determine the time window for the erection and demolition of the crossover bridge;

[0074] Train type: Understand the train type and load capacity of the trains passing through the construction site;

[0075] Emergency braking distance: Calculate the emergency braking distance according to the train type and speed to ensure that there is enough safety margin between the erection position of the crossover bridge and the emergency braking distance of the train;

[0080] In this step, by obtaining multi-dimensional structural data such as on-site three-dimensional data, track status change data, and operating line operation data, as well as a detailed understanding of the basic parameters of construction equipment, the actual situation of the operating line construction site can be comprehensively and accurately grasped; it helps with subsequent construction planning, design, and execution, ensuring the smooth progress of construction activities; the measurement and analysis of track geometric dimensions, material properties, and wear conditions, as well as an understanding of train operation plans and types, help determine the optimal time window for the erection and demolition of the crossover bridge, avoiding unnecessary interference to railway operations; at the same time, based on information such as the type, size, and movement method of construction equipment, a crossover bridge that better meets actual requirements can be designed, improving construction safety and efficiency; by conducting geological exploration and pipeline detection to understand the underground pipeline information beneath the construction site, damage to pipelines during the erection of the crossover bridge can be avoided, protecting the safety of underground facilities; at the same time, recording the building layout also helps avoid damage to existing buildings during construction; a detailed understanding of the basic parameters of construction equipment helps to reasonably arrange the allocation and use of construction resources according to the type, size, and operation requirements of the equipment; it can not only improve construction efficiency but also reduce construction costs; the acquisition and analysis of multi-dimensional structural data and construction equipment basic parameters provide a scientific basis for construction decision-making; it helps formulate more reasonable and feasible construction plans, ensuring the smooth progress of construction activities and the safety and stability of railway operations.

[0081] S2. Conduct a feasibility analysis on the multi-dimensional structural data to obtain the set of support points for the erection of the crossover bridge;

[0082] The method for obtaining the set of support points for the erection of the crossover bridge includes:

[0083] Clean and preprocess the multi-dimensional structural data; remove noise data and unify the formats of data from different sources for subsequent analysis;

[0084] Based on the on-site three-dimensional data, conduct a detailed assessment of the environmental and geological conditions; analyze the characteristics such as terrain undulation and gully distribution at the construction site, and evaluate the impact of the terrain on the erection of the crossover bridge; analyze the locations, heights, and structural types of existing buildings and structures at the site to determine their limitations and potential impacts on the erection of the crossover bridge, and evaluate whether it is necessary to demolish or move some buildings during the erection of the crossover bridge, as well as the related costs and risks; based on the underground pipeline information obtained through geological exploration and pipeline detection, analyze the pipeline routes, burial depths, and materials, and evaluate the impact of the erection of the crossover bridge on the underground pipelines to ensure that the normal operation of the pipelines will not be damaged or affected during the erection of the crossover bridge;

[0085] Evaluate the impact of the ferry bridge erection on the track based on the track status change data; measure the geometric dimensions of the track such as gauge, level, alignment, and direction, and evaluate whether they meet the requirements for the erection of the ferry bridge; analyze the change trend of the track geometric dimensions and predict the change of the track status in the next period of time; understand the track material and wear degree, and evaluate its bearing capacity and stability; analyze the impact of track wear on the ferry bridge erection, such as whether it is necessary to reinforce the track or adjust the ferry bridge design; consult the track maintenance history to understand the recent maintenance projects, maintenance time, and maintenance effects; evaluate the impact of the track maintenance records on the ferry bridge erection;

[0086] Combined with the operation data of the operating line, evaluate the possible impact on railway operation during the erection and use of the ferry bridge; obtain the train operation plan for the current and next period of time, and analyze information such as the departure time, arrival time, running speed, and train number of the train; determine the time window for the erection and demolition of the ferry bridge to avoid unnecessary interference to railway operation; calculate the emergency braking distance according to the type and speed of the train; ensure that there is enough safety margin between the erection position of the ferry bridge and the train emergency braking distance to cope with emergencies;

[0087] Comprehensively evaluate the analysis results of the data in each dimension, determine the feasibility of the ferry bridge erection, and determine the set of the best support points for the ferry bridge erection.

[0088] In this step, by cleaning and preprocessing the multi-dimensional structure data, noise is removed and the data format is unified, providing an accurate and consistent data basis for subsequent analysis; ensuring the accuracy and reliability of the analysis results and avoiding misjudgment caused by inconsistent or incorrect data; based on the on-site three-dimensional data, a detailed evaluation of the terrain undulation, gully distribution, location and structural type of buildings and structures is carried out, and the information of geological exploration and pipeline detection is considered at the same time, which helps to identify potential risks and challenges; by analyzing the geometric dimensions, material, wear degree, and maintenance history of the track, the impact of the ferry bridge erection on the track is accurately evaluated; helping to ensure that the erection of the ferry bridge will not damage the stability and bearing capacity of the track, and at the same time avoiding potential safety hazards caused by track problems; combined with the operation data of the operating line, the impact on railway operation during the erection and use of the ferry bridge is evaluated, and a reasonable erection and demolition time window is determined; helping to ensure that the ferry bridge erection work will not cause unnecessary interference to railway operation and ensuring the smoothness and safety of the railway; comprehensively evaluate the analysis results of the data in each dimension, determine the feasibility of the ferry bridge erection and the set of the best support points; ensuring the scientificity and rationality of the decision-making and improving the success rate and efficiency of the ferry bridge erection.

[0089] S3. Conduct a force analysis on the basic parameters of the construction equipment to obtain the lower limit index of the ferry bridge load-bearing capacity;

[0090] Methods for obtaining the lower limit index of the bridge load-bearing capacity include:

[0091] Based on the total weight of the construction equipment and its distribution on the bridge, calculate the maximum static load imposed by the equipment on the bridge. This process needs to take into account the differences in weight distribution of the equipment under different working conditions.

[0092] Consider the dynamic loads generated when construction equipment moves on the bridge, and conduct dynamic analysis, including evaluating the impact effect, vibration frequency and amplitude of the equipment movement on the bridge;

[0093] Consider the impact of environmental factors on equipment and bridges, including additional loads caused by wind, temperature changes, etc.;

[0094] Analyze the overall stability of the bridge when it is subjected to the load of construction equipment to ensure that the bridge will not overturn or slide under the load;

[0095] Based on the analysis results, determine the type of material used for the bridge and verify the bridge structure based on its mechanical properties. If the preliminary analysis shows that the existing design cannot meet the load-bearing requirements, the structural design of the bridge needs to be adjusted, such as adding support points, changing the cross-sectional shape or thickness of the beam, etc., until the best design solution that ensures both safety and economy is found.

[0096] Based on all the analysis results, the lower limit index of the ferry bridge's load-bearing capacity is determined. The lower limit index of the ferry bridge's load-bearing capacity is used to indicate the minimum load-bearing capacity that the ferry bridge must have to ensure that it can safely support the passage of the scheduled construction equipment. It not only reflects the structural strength of the ferry bridge itself, but also indirectly reflects the safety redundancy of the entire system.

[0097] In this step, by conducting a detailed force analysis of the basic parameters of the construction equipment, the lower limit index of the bridge load can be accurately calculated, thereby ensuring that the bridge has sufficient minimum load-bearing capacity to safely support the passage of the scheduled construction equipment; greatly reducing the safety risks caused by insufficient load-bearing; in the analysis process, the weight distribution differences of the equipment under different working conditions, the dynamic loads generated during movement, and the impact of environmental factors on the equipment and the bridge are considered, so that the design of the bridge is more in line with the actual situation and the accuracy and reliability of the design are improved; based on the analysis results, the structural design of the bridge can be adjusted and optimized to achieve the best design solution that can ensure safety and achieve economy; it helps to reduce construction costs and improve the economic benefits of the project; the determination of the lower limit index of the bridge load not only reflects the structural strength of the bridge itself, but also indirectly reflects the safety redundancy of the entire system; through the analysis of this step, it can provide a strong basis for construction decisions; this step not only ensures the safety of construction activities through detailed force analysis and structural design optimization, but also improves the accuracy and economy of the bridge design.

[0098] S4. Develop a construction plan for the temporary cross-track bridge according to the set of support points for the bridge erection and the lower limit index of the bridge's load-bearing capacity.

[0099] The method for developing a construction plan for the temporary cross-track bridge includes:

[0100] Select the bridge structure form according to the set of support points and the lower limit index of the load-bearing capacity; the bridge structure forms include beam bridges, arch bridges, suspension bridges, etc.

[0101] Select building materials according to the load-bearing requirements and durability requirements of the bridge; the building materials include steel, concrete, wood, etc.

[0102] Determine the span, width, and height of the bridge according to the size and weight distribution of the construction equipment; ensure that the bridge can accommodate the smooth passage of the construction equipment, while considering a certain safety margin.

[0103] Design the support structure based on the set of support points; this includes support columns, cross beams, connectors, etc., to ensure that the bridge has sufficient stability and stiffness when bearing loads.

[0104] Develop a detailed construction process, including the erection sequence of the bridge, construction time window, personnel division of labor, etc.; ensure that the construction activities can be carried out efficiently and orderly, while reducing the impact on railway operations.

[0105] Develop comprehensive safety measures, including safety management at the construction site, response measures for emergencies, etc.; ensure the safety of construction personnel and the safety of the bridge erection process.

[0106] The construction plan for the temporary cross-track bridge includes:

[0107] Use disk buckle scaffolds for erection; the longitudinal spacing of the vertical poles is 600 mm, locally 900 mm and 300 mm, and the transverse spacing is 600 mm; the step distance of the horizontal bars is 500 mm, and a full set of steel pipe horizontal scissors braces is arranged at the top layer of the horizontal bars; the main keel is erected with channel steel, and the secondary keel is laid flat with channel steel, and the secondary keel is the finished surface.

[0108] First lay the first channel steel longitudinally between the sleepers, then lay the second channel steel transversely, place the inverted top supports on the second channel steel according to the designed spacing, and then install the vertical poles.

[0109] Erect from both platforms towards the middle at the same time. When the vertical pole spacing and the horizontal bar length modulus do not match during the closure in the middle, use steel pipes for tying. Four are arranged horizontally and two are arranged vertically along the height direction. The tying rods are connected to the vertical poles of the scaffold through fasteners, and two connection points are set at each end.

[0110] To ensure that the coping stones are not damaged, thick formwork is laid on the platform surface, thick wooden planks are laid at the coping stones, thick formwork is nailed to the side to protect the side of the coping stones, and three sets of backstays are arranged at the bottom of the coping stones; three horizontal braces are arranged horizontally on the platform side wall and two horizontal braces are arranged vertically along the height direction. The horizontal braces are made of steel pipes sleeved with bottom supports. The steel pipes are connected to the vertical poles of the scaffold, and three connection points are set to protect the side wall and prevent the scaffold from tilting forward.

[0111] Since the carrying capacity of the trench cover plate is weak, it is prohibited to directly install the vertical poles on the trench cover plate. The vertical poles are supported by setting channel steel on the concrete surfaces on both sides of the trench cover plate; to avoid installing the vertical poles at the edge of the steps or conflicting with the communication pipeline positions, the vertical poles are supported by setting channel steel supporting beams.

[0112] The width of the overpass is expanded outwards on both sides. First, the rails are covered with quilts to prevent the generation of red light bands, and thick plywood hard protection is covered to prevent the materials from bumping against the rails during the erection process.

[0113] In this step, by comprehensively considering factors such as the set of support points, the minimum load-bearing index, the size and weight distribution of construction equipment, etc., the structural form and building materials of the overpass can be scientifically selected, and the span, width and height of the overpass can be accurately determined; it ensures that the overpass not only meets the construction requirements but also has sufficient safety margins; the support structure designed based on the set of support points, including support columns, cross beams, connectors, etc., ensures that the overpass has sufficient stability and stiffness when bearing loads; at the same time, the comprehensive safety measures formulated effectively guarantee the safety of construction personnel and the safety of the overpass erection process; by formulating a detailed construction process, including the erection sequence of the overpass, the construction time window, personnel division of labor, etc., it can ensure that the construction activities are carried out efficiently and orderly; it not only improves work efficiency but also reduces the impact on railway operations; the specific settings such as the use of disc buckle scaffolds for erection, the spacing of vertical poles and the step distance of horizontal poles mentioned in the plan show the adaptability and flexibility of the plan to different site conditions; during the erection of the overpass, protective measures are taken for key parts such as the platform surface, coping stones and side walls to avoid damage during the construction process; in addition, the plan also considers the reusability and environmental protection of materials, which helps to achieve sustainable development; the overpass erection plan for crossing tracks formulated in this step has multiple beneficial effects such as scientificity and accuracy, stability and safety, efficiency and orderliness, adaptability and flexibility, and protection and sustainability, providing a strong guarantee for the construction safety of the railway operating line.

[0114] S5. Erect a test overpass off-site according to the overpass erection plan for crossing tracks, and conduct a load-bearing test on the test overpass. Based on the erection process and the results of the load-bearing test, obtain an optimized overpass erection plan.

[0115] The erection method of the test overpass includes:

[0116] According to the construction plan for the temporary cross-track bridge, prepare the required construction materials, construction equipment and personnel;

[0117] Select an off-site location similar to the construction site environment of the operating line for building the test bridge;

[0118] Build the bridge on the off-site location according to the support point sets and structural design in the plan;

[0119] After completion of the construction, conduct a comprehensive quality inspection of the test bridge, including aspects such as dimensions, shape, material strength, etc.;

[0120] Ensure that the test bridge meets the requirements of the design plan and has the conditions for carrying out the load-bearing test;

[0121] Methods for conducting the load-bearing test on the test bridge include:

[0122] Prepare test loads similar to the weight and dimensions of the construction equipment to simulate the load effect of the actual construction equipment on the bridge;

[0123] Install monitoring equipment, including strain gauges and displacement sensors, to monitor the strain and displacement of the bridge under the action of the load;

[0124] Gradually increase the test load to simulate different positions and action modes of the construction equipment on the bridge;
