[0001] This invention relates to the technical field of ramp erection, and in particular to a method and structure for erecting a temporary ramp across a passenger tunnel for construction machinery entering a commercial railway line. Background Technology
[0002] During the rapid development of high-speed railways in my country, steel structures were widely used in the construction of high-speed railway stations. However, with the increase in service life, and given that most steel structure canopies are located in semi-open or open environments, they are significantly affected by climate, and corrosion problems have become apparent. Considering the actual construction conditions of the station canopy steel structure, it is necessary to transport spider cars across platforms and develop a plan for a bridge crossing the passenger underpass to successfully complete the erection and dismantling and allow vehicle passage within a single maintenance window.
[0003] During the construction and maintenance of railway operating lines, large construction machinery is often required to enter specific work areas. However, when the construction area is located above or near a passenger tunnel, the access of construction machinery becomes a complex issue. Due to the presence of the passenger tunnel, direct access to the construction area may be severely restricted, especially in environments with complex terrain and variable geological structures. Therefore, there is an urgent need for a method and structure for erecting temporary ramps across passenger tunnels for the access of construction machinery on railway lines. Summary of the Invention

Simultaneously, the method offers flexibility, allowing for adjustments and optimization based on different terrain features and construction machinery types, making it suitable for construction needs in various complex environments. It helps reduce construction costs, improve construction quality and efficiency, and also contributes to raising the overall construction level and technical standards of the industry. Through precise calculation and evaluation, this method can reduce unnecessary material waste and energy consumption. Furthermore, by optimizing the climbing scaffolding erection scheme, it can minimize interference and damage to the surrounding environment, achieving harmonious coexistence between construction and the environment.

[0063] This application will now be described with reference to the accompanying drawings.
[0064] Example 1: As Figure 1 As shown, the method for erecting a temporary ramp scaffold across a passenger tunnel for construction machinery entering the operational railway line according to the present invention specifically includes the following steps:
[0065] S1. Obtain terrain feature data across the passenger tunnel, the terrain feature data including topographic information, geological structure information, and tunnel internal size information;
[0066] A detailed on-site survey of the passenger tunnel and its surrounding topography was conducted, including recording the tunnel's specific location, surrounding environment, terrain undulations, surface coverings, and obstacles. Aerial photography was conducted using drones to obtain an overhead view of the tunnel and a 3D image of the surrounding environment. Based on the aerial photography data, a 3D model of the tunnel was constructed using 3D modeling software to provide a more intuitive understanding of the topographic features.
[0067] Geological exploration methods are used to obtain geological structure information of the tunnel and its surrounding area; this includes key parameters such as soil layer distribution, rock layer thickness, groundwater level, and soil bearing capacity; historical geological data of the area are reviewed to understand geological structure, seismic activity history, and other information in order to assess potential geological hazard risks;
[0068] Use measuring tools to accurately measure the width, height, length, and dimensions of any obstacles inside the tunnel; verify the measurements against the design drawings to ensure accuracy and understand the tunnel's structural features and design requirements;
[0069] The collected topographic and geomorphological information, geological structure information, and tunnel internal size information are integrated to form a complete topographic feature dataset.
[0070] In this step, a detailed topographic and geomorphological survey, geological exploration, and internal dimension measurement of the passenger tunnel and its surrounding area are conducted to comprehensively and accurately obtain topographic feature data of the area. This provides a solid foundation for subsequent planning, design, construction, and safety management. Based on the collected topographic feature dataset, decision-makers can formulate relevant plans more scientifically. During the planning stage, the location and orientation of the tunnel can be optimized based on topographic and geomorphological information and geological structure information to reduce damage to the natural environment and the risk of geological disasters. During the construction stage, appropriate construction methods and materials can be selected based on the tunnel's internal dimensions and structural characteristics. The geological structure information obtained through geological exploration can help assess potential geological disaster risks and facilitate early intervention. Corresponding preventative measures are implemented to ensure the safety of the tunnel and its surrounding area. Precise measurements of the tunnel's internal dimensions also help identify potential safety hazards, allowing for timely rectification. Utilizing drones for aerial photography and 3D modeling software to construct a 3D model of the tunnel provides a clear visual representation of the terrain and tunnel structure, enabling personnel to quickly understand the situation and improve work efficiency. Furthermore, these digital tools facilitate data sharing and collaboration, promoting communication and cooperation within the team. A complete dataset of terrain features not only provides a basis for tunnel construction but also serves as an important reference for subsequent maintenance and management. During the maintenance phase, targeted maintenance plans can be developed based on geological structure information and tunnel internal dimensions to ensure the long-term stable operation of the tunnel.
[0071] S2. Based on terrain feature data and pre-acquired construction machinery parameters, set up a climbing frame erection plan;
[0072] The parameters of the construction machinery include:
[0073] Machinery weight and size: The weight and size of construction machinery are key factors that must be considered when designing ramps; it is necessary to ensure that the ramps can withstand the weight of the machinery and that their size is sufficient to allow the machinery to pass through.
[0074] Mechanical movement method: Different construction machinery has different movement methods, which will affect the design of the climbing frame;
[0075] Machinery operation requirements: Construction machinery requires a certain amount of operating space during operation, which needs to be considered when designing the ramp frame to ensure that the machinery can smoothly enter and exit the tunnel and carry out operations;
[0076] The steps for setting up a ramp erection plan include:
[0077] Based on the analysis results, the materials for the ramp scaffolding should be selected to ensure sufficient structural strength while minimizing its weight to facilitate quick assembly and disassembly.
[0078] The climbing frame structure was determined based on terrain feature data and construction machinery parameters;
[0079] The specific layout of the climbing frame needs to be planned, including the location and spacing of the support points, as well as the connection methods between the components. At the same time, it is also necessary to consider how to complete the on-site assembly and disassembly work conveniently and quickly to meet the needs of completing the work within a single daylight window.
[0080] Based on the workload and available time window, schedule the timeline for each construction phase to ensure that all work proceeds in an orderly manner.
[0081] Determine the number of people involved in the construction and their division of responsibilities to ensure that each stage has a designated person in charge, thereby improving work efficiency while ensuring construction safety;
[0082] Develop corresponding contingency plans for potential problems, make preparations in advance, and reduce the impact of unexpected events on the construction progress.
[0083] In this step, by comprehensively considering terrain feature data and construction machinery parameters, a more practical climbing scaffold erection scheme can be designed. This not only ensures that construction machinery can smoothly enter and exit the tunnel and carry out operations, but also improves the efficiency of erection and dismantling through reasonable layout and material selection, while ensuring safety during construction. The climbing scaffold erection scheme fully considers the workload and available time windows, thus enabling a reasonable scheduling of the timetable for each construction stage. This helps optimize the allocation of construction resources, avoid waste and idleness, and improve overall construction efficiency. The design of the climbing scaffold erection scheme fully considers the variability of terrain feature data and construction machinery parameters, making the scheme more... It offers a degree of flexibility and adaptability; it helps to cope with various situations that may arise during construction, ensuring the smooth progress of construction work; by planning the specific layout of the climbing frame, the location and spacing of support points, and the connection methods between various components in detail, it can ensure the structural strength and stability of the climbing frame; it helps to improve the quality control level during construction and reduce safety hazards caused by structural problems; when formulating the climbing frame erection plan, it not only considers construction efficiency and quality, but also focuses on ensuring construction safety; by determining the number of people involved in the construction and their division of responsibilities, and by formulating corresponding emergency plans, it can make preparations in advance, reduce the impact of unexpected events on the construction progress, and ensure the safe progress of construction work.
[0084] S3. Extract safety indicators from the terrain feature data to obtain a set of safety analysis indicators for the temporary climbing frame across the passenger tunnel; the set of safety analysis indicators includes the maximum allowable slope, ground flatness, soil bearing capacity, soil layer distribution and properties, clearance height and width, and tunnel structure stability.
[0085] The maximum allowable slope is analyzed, including the slope of the tunnel and its variations. The slope affects the tilt angle and stability of the climbing frame.
[0086] Ground flatness: Assess the flatness of the ground around the tunnel, including whether there are large undulations, potholes or cracks; ground flatness affects the support and stability of the climbing frame, and foundation treatment may be necessary.
[0087] Soil bearing capacity: Based on the geological survey report, assess the soil bearing capacity of the area where the tunnel is located; soil bearing capacity is an important basis for determining the foundation size and burial depth of the climbing frame to ensure that the climbing frame is not affected by foundation settlement or collapse;
[0088] Soil layer distribution and properties: Analyze the distribution and properties of soil layers, such as whether there are soft soil layers, expansive soil or frozen soil; special soil layers can have an adverse effect on the stability of the climbing frame, and corresponding foundation reinforcement measures need to be taken.
[0089] Clearance height and width: Measure the clearance height and width of the tunnel to ensure that the climbing frame and the construction machinery on it can pass smoothly; at the same time, consider the operating space and safety clearance of the machinery during the passage process;
[0090] The stability of the tunnel structure is assessed, including the load-bearing capacity of the walls and the stability of the arch; it is ensured that the erection of the ramp frame will not damage or affect the tunnel structure.
[0091] In this step, through in-depth analysis of terrain feature data, key safety indicators are extracted. These indicators provide clear safety standards for the design and erection of the climbing frame, helping to ensure sufficient stability and load-bearing capacity during use, thereby greatly improving safety during construction. The extraction of safety analysis indicators makes the design of the climbing frame more scientific and reasonable. Designers can adjust the structure, size, and materials of the climbing frame according to these indicators to adapt to different terrain and geological conditions. This not only improves the applicability and reliability of the climbing frame but also reduces construction costs and time. By evaluating indicators such as soil layer distribution and properties, and tunnel structure stability, potential safety risks can be identified and prevented in a timely manner. This is especially important for soft soil layers or expansive soils. For special soil layers such as silt, foundation reinforcement measures can be taken to enhance the stability of the climbing frame; for structurally unstable tunnels, additional support measures can be taken to ensure safety; guided by safety analysis indicators, the erection and dismantling process of the climbing frame can be more orderly and efficient; construction personnel can select appropriate erection methods and tools based on these indicators, thereby reducing unnecessary waste and delays; at the same time, clear safety standards also help construction personnel understand and execute construction tasks more quickly; the set of safety analysis indicators provides strong data support for decision-makers; in the decision-making process, decision-makers can comprehensively consider these indicators to formulate more reasonable and feasible construction plans; this helps to ensure the smooth progress of the construction process while reducing potential safety risks.
[0092] S4. Based on the set of safety analysis indicators and combined with the parameters of construction machinery, data fitting is performed, and a safety analysis model of the temporary climbing frame across the passenger tunnel is constructed based on the fitted data.
[0093] The method for constructing the security analysis model includes:
[0094] The safety analysis index set and construction machinery parameters of the temporary climbing frame across the passenger tunnel were integrated, and the integrated data were standardized.
[0095] Based on the complexity of the problem and the availability of data, a mathematical model is selected as the basic architecture of the safety analysis model. The mathematical model includes a finite element analysis model, a structural mechanics model, and a geomechanics model.
[0096] The standardized data is divided into training and test sets in a 70% ratio and a 30% ratio, respectively. The training set is used for parameter estimation and learning of the model, while the test set is used to evaluate the model's generalization ability.
[0097] The training set data is used to estimate the parameters of the model. During the training process, the parameters of the model are continuously optimized through iteration to minimize the prediction error of the model on the training set.
[0098] The trained model is evaluated using test set data. Commonly used evaluation metrics include mean squared error (MSE), root mean square error (RMSE), mean absolute error (MAE), and coefficient of determination.
[0099] The optimized model is validated using methods such as cross-validation to ensure its stability and reliability.
[0100] Deploy validated security analysis models into real-world applications for subsequent evaluation.
[0101] In this step, by integrating the safety analysis index set of the temporary climbing frame across the passenger underpass and the construction machinery parameters, and performing standardization processing, a comprehensive and accurate data foundation is provided for constructing the safety analysis model. Selecting an appropriate mathematical model as the basic architecture of the safety analysis model further ensures the model's scientific validity and accuracy. The constructed safety analysis model can fit the input data, thereby achieving the prediction and assessment of the safety of the temporary climbing frame across the passenger underpass. Predictive capability helps identify potential safety risks before construction and take corresponding preventative measures to reduce the probability of accidents. By dividing the data proportionally into training and test sets, and using the training set data to estimate the model's parameters, the prediction error of the model on the training set is minimized; while using the test set... Evaluating the model using data can test its generalization ability, i.e., its performance on new data; it helps ensure the model's effectiveness and reliability in practical applications; using methods such as cross-validation to validate the optimized model can further ensure its stability and reliability, evaluate its performance on different datasets, thereby avoiding overfitting or underfitting, and improving the model's generalization ability and robustness; the validated safety analysis model can be deployed in practical applications for subsequent evaluation; it helps construction personnel monitor the safety of the climbing frame in real time during construction, promptly identify and address potential safety hazards, and ensure the smooth progress of construction; at the same time, the model can also provide a scientific basis for the formulation and optimization of construction plans, improving construction efficiency and safety.
[0102] S5. Input the climbing frame erection plan into the safety analysis model, evaluate it, and obtain the climbing frame operation safety index.
[0103] The climbing frame erection plan is refined into specific parameters and indicators, which are matched with the input data required in the safety analysis model; including the geometry of the climbing frame, material properties, design of the support structure, and expected load capacity.
[0104] The refined scheme data format is converted into a format that the model can recognize;
[0105] Load the prepared data into the security analysis model;
[0106] The model is started for simulation. During the simulation, a static analysis is first performed to check the overall stability of the climbing frame and the stress distribution of key parts under the condition of no external dynamic forces. The purpose is to ensure that the structure will not deform or be damaged in a static state. Then, a dynamic analysis is performed to simulate the impact of dynamic loads generated during the movement of construction machinery on the climbing frame. Dynamic loads often have a greater impact on the structure than static loads, especially in the presence of vibration or impact. In order to fully understand the performance of the climbing frame under various extreme conditions, limit state analysis is also required.
[0107] After the simulation is completed, the model generates the safety index for the ramp-climbing frame operation.
[0108] In this step, by refining the ramp-climbing scaffold erection plan into specific parameters and indicators and inputting them into a validated safety analysis model, the operational safety of the ramp-climbing scaffold under various conditions can be accurately assessed. This is more accurate and scientific than traditional experience-based judgments or simple calculations, enabling the identification of potential safety hazards and timely implementation of improvement measures. The safety analysis model not only performs static analysis, examining the overall stability and stress distribution of the ramp-climbing scaffold under no external dynamic forces, but also performs dynamic analysis and limit state analysis. This helps to comprehensively understand the performance of the ramp-climbing scaffold under various extreme conditions, thereby ensuring the safety and reliability of the ramp-climbing scaffold in actual use. Through the simulation operation of the safety analysis model, the operational safety index of the ramp-climbing scaffold can be quickly generated, providing a basis for further analysis. The assessment provides decision-makers with intuitive results, enabling them to make quick decisions, optimize construction plans, improve construction efficiency, and reduce safety risks. During the assessment process, if safety hazards are found in the climbing frame under certain conditions, the safety of the climbing frame can be optimized by adjusting the parameters and indicators in the design plan. Accurate safety assessment of the climbing frame can avoid construction delays and additional costs caused by safety hazards. Furthermore, the optimized design plan may utilize more economical and reasonable materials and structures, further reducing construction costs. The assessment results of the safety analysis model provide important safety guidance for construction personnel, ensuring they follow safety regulations and take necessary safety measures during construction, thereby reducing the risk of construction accidents.
[0109] S6. Compare the operating safety information of the ramp frame with the preset safety factor qualification threshold. If the operating safety information of the ramp frame exceeds the preset safety factor qualification threshold, it means that the ramp frame erection scheme can meet the requirements.
[0110] The factors influencing the setting of the preset safety factor qualification threshold include:
[0111] Structural stability requirements: The strength of the materials used in the climbing frame directly determines its load-bearing capacity; based on the mechanical properties of the materials and actual usage, a reasonable safety factor needs to be set to ensure that the climbing frame remains stable under maximum load; the structural design of the climbing frame, including the arrangement of support points, the cross-sectional dimensions of beams and columns, etc., will affect its stability; the overall stiffness and local stability of the structure should be considered during the design, and an appropriate safety factor should be set.
[0112] Construction machinery parameters: The weight and dimensions of construction machinery are important references for the design of ramp frames; an appropriate safety factor needs to be set according to the actual machinery parameters to ensure that the ramp frame can bear the weight of the machinery and remain stable; the dynamic loads generated by the construction machinery during movement are also factors to be considered; these loads may include the impact forces generated by starting, braking, turning and other actions, as well as the bumps when the machinery travels on uneven ground;
[0113] Environmental factors: The terrain and topography of the passenger tunnel, such as slope, ground hardness, and soil bearing capacity, will affect the stability of the ramp; it is necessary to set an appropriate safety factor according to the actual terrain conditions.
[0114] Risk assessment: By conducting a risk assessment of the scaffolding erection plan, potential safety hazards and risk factors can be identified; based on the risk assessment results, corresponding safety factors can be set to reduce risks.
[0115] In this step, by comparing the safety information of the climbing frame operation with the preset safety factor qualification threshold, it can be ensured that the climbing frame erection plan meets certain safety standards while satisfying structural stability requirements, adapting to construction machinery parameters, and adapting to environmental factors. This avoids potential safety hazards and ensures safety and compliance during construction. Setting a reasonable safety factor qualification threshold and evaluating the climbing frame operation safety information based on this threshold makes the decision-making process more scientific and objective. It helps to avoid biases caused by subjective judgment and improves the accuracy and reliability of decision-making. When setting the safety factor qualification threshold, structural stability requirements need to be comprehensively considered. The process involves considering multiple factors, including construction machinery parameters, environmental factors, and risk assessment results. By comprehensively considering these factors, resources can be allocated more rationally, thereby improving construction efficiency and reducing costs. By setting corresponding safety factors through risk assessment, potential safety hazards and risks in the climbing frame erection scheme can be identified, and corresponding preventive measures can be taken. This helps to enhance the ability to cope with risks and reduce the probability of accidents and losses. By comparing the safety information of the climbing frame operation with the preset safety factor qualification threshold, problems can be identified in a timely manner and corresponding improvement measures can be taken. This helps to promote continuous improvement and optimization of the construction process, and improve the overall construction quality and safety.
[0116] S7. Erect the ramp scaffolding on site according to the evaluation and comparison plan;
[0117] Before setting up the ramp, the site should be cleared, and all obstacles that may hinder the erection should be removed to ensure that the site is flat and unobstructed.
[0118] According to the climbing frame erection plan, use measuring tools to mark the exact location of the climbing frame on site, including key locations such as support points and connection points;
[0119] Based on the design plan of the climbing frame, purchase the necessary steel, connectors, fasteners and other materials, and ensure that the quality of the materials meets the relevant standards; inspect the purchased materials to ensure that there are no defects such as rust, cracks and deformation, and at the same time check whether the specifications and models of the materials are consistent with the design plan;
[0120] According to the design plan, the first step is to build the support structure of the ramp frame, including columns and beams, to ensure that the support structure is stable and vertical. Connectors such as welding and bolting are then installed between the support structures to ensure that the connections are firm and reliable. Ramp panels are then laid on the support structure. The panels should be flat and non-slip to ensure that construction machinery can move smoothly. During the construction process, the stability, verticality, flatness, and other indicators of the ramp frame are constantly checked, and any deviations are adjusted in a timely manner.
[0121] Conduct a visual inspection of the ramp frame to ensure there are no issues such as deformation, looseness, or missing parts; apply a certain load to the ramp frame to simulate the actual use of construction machinery and check its load-bearing capacity and stability; place safety warning signs in prominent locations on the ramp frame to remind construction workers to pay attention to safety.

[0132] Multiple support brackets 1 are connected end to end, forming a continuous support surface; these support brackets 1 are arranged in two parallel groups to ensure the stability and load-bearing capacity of the construction machinery during the climbing process; the support brackets 1, as the main load-bearing components of the climbing frame, are responsible for supporting the weight of the construction machinery and preventing it from sinking or tilting; they are set on the ground, connecting and supporting each adjacent support bracket 1; connecting plates 11 are fixedly connected to two adjacent support brackets 1 to ensure the stability and continuity between the support brackets 1; the main support column 12 is fixedly connected to the connecting plate 11 to transfer the weight on the support brackets 1 to the ground; the bottom end of the main support column 12 is equipped with... A support plate is provided to increase the contact area with the ground and improve stability; the diagonal brace connecting rod 13 is fixedly inserted into the support bracket 1, providing a connection point for the diagonal brace 14; the diagonal braces 14 are respectively set on both sides of the main support column 12, with the bottom connected to the bottom of the main support column 12 and the top fixedly connected to the corresponding diagonal brace connecting rod 13; the diagonal braces 14 provide additional stability and support force to prevent the main support column 12 from bending or tilting under stress; the main support node is a key support structure of the climbing frame, ensuring the stability and load-bearing capacity of the entire climbing frame; the intermediate support node is set in the middle part of the support bracket 1. Provides additional support; intermediate support nodes further enhance the overall rigidity and stability of the climbing frame, especially when the span of the support bracket 1 is large or the weight of the construction machinery is heavy; when the construction machinery drives onto the climbing frame, its weight is first borne by the support bracket 1; since the support bracket 1 is set in two parallel sets, the weight of the construction machinery can be distributed to prevent single-point overload; the weight of the construction machinery is transferred to the main support node through the support bracket 1; the connecting plate 11 ensures the stable connection between the support brackets 1, forming an integral structure; the main support column 12 transfers the weight to the ground, supporting the weight of the entire climbing frame; diagonal brace 1 4 and the diagonal brace connecting rod 13 provide additional stability and support; the arrangement of the diagonal brace 14 enables it to provide support perpendicular to the direction of the main support column 12, enhancing the overturning resistance of the entire structure; the intermediate support node provides additional support in the middle part of the support bracket 1, further enhancing the overall rigidity and stability of the climbing frame; these nodes disperse the stress on the support bracket 1, preventing structural damage caused by local overload; the structural design of the temporary climbing frame across the passenger tunnel fully considers the weight and stability requirements of the construction machinery, ensuring the safety and stability of the construction machinery during the climbing process.
[0133] Intermediate support nodes include:
[0134] Angle steel 21 is fixedly installed in the middle of support bracket 1;
[0135] The intermediate support column 22 is fixedly connected to the supporting angle steel 21, and a support plate is provided at the bottom end of the supporting angle steel 21. The intermediate support column 22 is supported on the ground.
[0136] The connecting beam 23 is fixedly connected to the support angle steel 21 of the two sets of parallel support brackets 1.
[0137] The supporting angle steel 21 is fixedly installed in the middle of the support bracket 1, providing support and reinforcement for the middle part of the support bracket 1. The supporting angle steel 21 distributes the weight of the middle part of the support bracket 1 more evenly onto the ground, while increasing the bending strength of the support bracket 1 and preventing bending or deformation under stress. The intermediate support column 22 is fixedly connected to the supporting angle steel 21, and a support plate is provided at the bottom of the supporting angle steel 21. The intermediate support column 22 is supported on the ground. The intermediate support column 22 is the core support component of the intermediate support node, responsible for transferring the weight of the middle part of the support bracket 1 to the ground, while providing additional stability and support force. The presence of the support plate increases the contact area between the intermediate support column 22 and the ground, improving its stability. The connecting beam 23 is fixedly connected to the supporting angle steel 21 of the two sets of parallel support brackets 1. The connecting beam 23 connects the two sets of parallel support brackets 1 into a whole, enhancing the overall rigidity and stability of the climbing frame. Simultaneously, the connecting beam 23 can further distribute the support weight. The stress on the support frame 1 is prevented from causing structural damage due to local overload. When construction machinery travels on the climbing frame, its weight is transferred to the support frame 1. The support frame 1 then transfers the weight to the main support node and the intermediate support node. The supporting angle steel 21 and the intermediate support column 22 of the intermediate support node work together to support the weight in the middle of the support frame 1 and transfer it to the ground. At the same time, the support plate at the bottom of the supporting angle steel 21 increases the contact area with the ground, improving the stability of the support. The connecting beam 23 connects the two sets of parallel support frames 1 into a whole, enhancing the overall rigidity and stability of the climbing frame. This connection method can prevent the support frame 1 from relative displacement or deformation when under stress, thereby ensuring the overall stability of the climbing frame. Through the combined action of the supporting angle steel 21, the intermediate support column 22 and the connecting beam 23, the stress on the support frame 1 can be more evenly distributed to the ground. This not only prevents the support frame 1 from being damaged due to local overload, but also improves the load-bearing capacity and service life of the entire climbing frame.
