Description

Technical Field

[0001] This invention belongs to the field of evacuation platform design technology, specifically relating to an evacuation platform deployment method, a computer-readable storage medium, and a computer device. Background Technology

[0002] Evacuation platforms are important auxiliary components on rail transit bridges and tunnels, providing fire safety evacuation routes during rail transit operation. Evacuation platforms are generally assembled on-site from prefabricated components. During the civil construction of the main structure of bridges and tunnels, attention should be paid to reserving foundations for the installation of evacuation platforms. After the evacuation platform construction is completed, special attention should be paid to clearance checks. The main problems in the design and construction of evacuation platforms are as follows: the evacuation platform layout parameter tables provided in the design are often too rough, failing to provide a set of parameters for each slab and column, making high-precision construction difficult; at the same time, during the construction of the main structure, the foundation of the evacuation platform is often subject to significant pre-embedding deviations because only relative distances are given without accurate coordinates, frequently resulting in omissions or incorrect installations on-site. Summary of the Invention

[0003] To overcome the above-mentioned technical defects, the first aspect of the present invention provides a method for deploying an evacuation platform, comprising the following steps: S1. Obtain the structural span data table, and determine the mileage value of each column position of the evacuation platform on each span structure according to the specific evacuation platform division principle based on the structural span data table. S2. Select the left and right lines of the horizontal curve of the route. Based on the mileage value obtained in step S1, calculate the point Zpt on the left line and the point Ypt on the right line corresponding to each evacuation platform column. Based on the point Zpt on the left line and the point Ypt on the right line, calculate the line spacing between the left and right lines of the column position. S3. Determine the structural form of the evacuation platform based on the line spacing; S4. Calculate the coordinates of the center point of the evacuation platform column based on the structural form of the evacuation platform; S5. Obtain the superelevation data table for the left track and the superelevation data table for the right track. Based on the superelevation data table for the left track, the superelevation data table for the right track, and the mileage value obtained in step S1, interpolate to obtain the superelevation value for the left track and the superelevation value for the right track at the mileage position of the column. S6. Based on the superelevation value calculated in S5, calculate the clearance values ​​at the evacuation platform column relative to the left and right lines according to the clearance calculation formula provided by the clearance specialist. S7. Based on the line spacing obtained in step S2, the center point coordinates obtained in step S4, the fixed offset value, and the limit value calculated in step S6, calculate the distance from the center point of an evacuation platform column to the left line, the distance from the center point to the right line, and the net width of the evacuation platform. S8. Repeat steps S1 to S7 to calculate the distance from the center point of each evacuation platform column to the left line, the distance from the center point to the right line, and the net width of the evacuation platform. Combine the line file, structural span data table, track superelevation data table, and clearance parameters to calculate the position of the evacuation platform column and the size of the evacuation platform plate. Save the position of the evacuation platform column and the size of the evacuation platform plate as an evacuation platform layout plan.

[0004] As a further improvement of the present invention, step S3 includes: S31. When the line spacing is less than or equal to the line spacing S1, a double-line type I evacuation platform shall be adopted. S32. When the line spacing is greater than the line spacing S1 and less than or equal to the line spacing S2, a Type II evacuation platform shall be used. S33. When the line spacing is greater than the line spacing S2, a single-line type I evacuation platform shall be adopted.

[0005] As a further improvement of the present invention, in step S4, when the line spacing is less than or equal to the line spacing S2, the center point of the evacuation platform column is the midpoint of point Zpt and point Ypt; when the line spacing is greater than the line spacing S2, the center point of the evacuation platform column is calculated based on point Zpt, point Ypt, and a fixed offset value.

[0006] As a further improvement of the present invention, step S6 includes: S61. When point Zpt is located on the circular curve or transition curve segment of the left and right lines, calculate the curve radius of point Zpt and point Zpt. Based on the curve radius and the evacuation platform clearance calculation formula, calculate the clearance value of the evacuation platform column relative to the left and right lines. S62. When Zpt and point Zpt are located on the straight segments of the left and right lines, the limit value of the evacuation platform column relative to the left and right lines is the standard net distance from the center line of the line to the edge of the platform.

[0007] As a further improvement of the present invention, after step S8, the method further includes: S9. Draw a plan of the entire evacuation platform layout based on the evacuation platform layout data table.

[0008] As a further improvement of the present invention, step S9 includes: S91. Based on the evacuation platform layout data table, place the evacuation platform column blocks; S92. Draw the evacuation platform board based on the evacuation platform layout data.

[0009] As a further improvement of the present invention, after step S8, the method further includes: S10. Based on the evacuation platform layout data table, derive the center coordinates of each evacuation platform column and the theoretical dimensions of each evacuation platform panel.

[0010] As a further improvement of the present invention, after step S9, the method further includes: S11. For evacuation platform sections where it is difficult to determine whether they encroach on the boundary, and based on the on-site measurement data, generate an actual evacuation platform layout plan according to step S9. Then compare it with the theoretical evacuation platform layout plan generated in S9 to determine whether the on-site evacuation platform slabs encroach on the boundary and determine the adjustment method.

[0011] A second aspect of the present invention provides a computer-readable storage medium, characterized in that the readable storage medium stores at least one instruction, at least one program, code set, or instruction set, wherein the at least one instruction, at least one program, code set, or instruction set is loaded and executed by a processor to implement the above-described evacuation platform deployment method.

Detailed Implementation

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example 1 This embodiment provides a method for deploying evacuation platforms, such as... Figure 1 As shown, the steps include: S1. Obtain the structural span data table (e.g., ...) Figure 2 As shown), based on the structure span data table, the starting mileage Lci and ending mileage Lcj of a span structure are obtained, and then the span length L = Lcj - Lci is obtained, according to L = D + E + n*B + E + D (as shown). Figure 3 The division principle (where D is the structural joint width, B is the standard span length of the evacuation platform, n is the number of standard spans of the evacuation platform, and E is the span length of a non-standard span at each end) determines the mileage value CTi of each column position of the evacuation platform. S2. Select the left and right lines of the horizontal curve of the route. Based on the mileage value CTi of each evacuation post, calculate the point Zpt on the left line and the point Ypt on the right line corresponding to each evacuation platform post. Based on the points Zpt on the left line and Ypt on the right line, calculate the line spacing S between the left and right lines of the post position (e.g., ...). Figure 4 As shown in the figure, the line spacing S is the distance between points Zpt and Ypt; S3. Determine the structural form of the evacuation platform based on the line spacing S, such as... Figure 5 As shown; S31. When the line spacing S ≤ line spacing S1, a double-line type I evacuation platform is used, such as... Figure 6 As shown; S32. When the line spacing S1 < line spacing S ≤ line spacing S2, a Type II evacuation platform is used, such as... Figure 7 As shown; S33. When the line spacing S > line spacing S2, a single-line Type I evacuation platform is used, such as... Figure 8 As shown.

[0017] Among them, line spacing S1 and line spacing S2 are user-defined line spacing threshold values.

[0018] S4. Calculate the center point of the evacuation platform column based on the structural form of the evacuation platform; specifically, when the line spacing S ≤ line spacing S2, i.e., when using a double-line Type I evacuation platform or a double-line Type II evacuation platform, the center point of the evacuation platform column is the midpoint mpt of points Zpt and Ypt (e.g., ...). Figure 9 (As shown); when the line spacing S > line spacing S2, that is, when a single-line type I evacuation platform is used, the evacuation platform is divided into left and right sections (as shown). Figure 10 As shown in the figure, the center point of the evacuation platform column is calculated based on point Zpt, point Ypt, and fixed offset value PYZ. The center point of the evacuation platform column includes the left center point Lpt and the right center point Rpt.

[0019] S5. Obtain the superelevation data tables for the left and right tracks (e.g., ...). Figure 9 As shown in the figure, based on the superelevation data table of the left track, the superelevation data table of the right track, and the mileage value CTi, the superelevation values ​​of the left track and the right track are obtained by interpolation at the mileage position. S6. Calculate the clearance values ​​at the evacuation platform columns relative to the left and right lines, including the following steps: S61. When point Zpt is located on the curved or transitional curve segment of the left and right lines, calculate the curve radius of point Zpt and point Zpt. Based on the curve radius and the evacuation platform clearance calculation formula, calculate the clearance value Bs(Bs_z, Bs_y) of the evacuation platform column relative to the left and right lines. When the platform is located outside the curve:

[0020] If the calculated result is less than Bs0mm, the value Bs0 is used.

[0021] When the platform is located inside the curve:

[0022] in: Bs: Clear distance from the centerline of the line to the edge of the platform; Bs0: Standard clearance from the centerline to the edge of the platform when the line is a straight segment (fixed value, provided by the clearance specialist); Cgi: Orbital superelevation value (obtained in step S5); R: Curve radius value; h: Height of the evacuation platform above the rail surface (fixed value, provided by the clearance specialist); CS1, CS2: Clearance parameters for evacuation platforms (fixed values, provided by clearance specialists); S62. When Zpt and point Zpt are located on the straight segments of the left and right lines, the limit value of the evacuation platform column relative to the left and right lines is the standard net distance Bs0 from the center line of the line to the edge of the platform.

[0023] S7. Based on the line spacing S, center point mpt or Lpt, Rpt, fixed offset value PYZ, limit value Bs, Bs0, and single-side fixed value C0 of a single-line evacuation platform column, calculate the distance C1 from the center point to the left line, the distance C2 from the center point to the right line, and the net width C of the evacuation platform. For a dual-line evacuation platform: C1 = S / 2 - Bs_z; C2 = S / 2 - Bs_y; C = C1 + C2; For a single-line evacuation platform: C1=PYZ-Bs_z; C2=PYZ-Bs_y; C=C1+C0 (left line), C=C2+C0 (right line); S8. Repeat steps S1 to S7, calculating the distance C1 from the center point mpt (Lpt, Rpt) of each evacuation platform column to the left line, the distance C2 from the center point to the right line, and the net width C of the evacuation platform; combining the route file, structural span data table, track superelevation data table, and clearance parameters, calculate the position of the evacuation platform columns and the dimensions of the evacuation platform slabs, and save the position of the evacuation platform columns and the dimensions of the evacuation platform slabs as an evacuation platform layout plan, such as... Figure 9 and Figure 10 As shown.

[0024] To further improve design efficiency, this embodiment also adds a quick drawing output step, that is, after step S8, it further includes: S9. Draw a plan layout of the evacuation platform slabs along the entire line based on the evacuation platform layout data table, specifically including: S91. Based on the evacuation platform layout data table, read the coordinates of the center point (mpt, Lpt, Rpt) of each evacuation platform column. Place a batch of evacuation platform column blocks at the center point locations. There are three block types, corresponding to double-line Type I evacuation platforms, double-line Type II evacuation platforms, and single-line Type I evacuation platforms, respectively. This will give the plan layout of the entire evacuation platform column (e.g., ...). Figure 11 ).

[0025] S92. Based on the evacuation platform layout data, read the coordinates of the center point mpti (Lpti, Rpti) of any evacuation platform column, the distance from the center point to the left line C1i, the distance to the right line C2i, and the net width Ci of the evacuation platform. Also, read the coordinates of the center point mptj (Lptj, Rptj) of the adjacent evacuation platform column, the distance from the center point to the left line C1j, the distance to the right line C2j, and the net width Cj of the evacuation platform. This will allow you to draw the plan layout of the entire evacuation platform (e.g., ...). Figure 11 ).

[0026] In order to provide the construction unit with the coordinates of the evacuation platform columns and the parameter table of the evacuation platform slab, so as to facilitate the construction unit's precise control and construction, the following is included after step S8: S10. According to the evacuation platform layout data table (e.g.) Figure 12 As shown in the diagram, the center coordinates of each evacuation platform column are derived. This facilitates precise positioning of the base and pre-embedding of reinforcing bars, fundamentally eliminating the possibility of omissions or mis-embedding. Since each evacuation platform base in this process is precisely positioned using coordinate control, construction errors are strictly controlled, reducing the workload of on-site measurements in subsequent processes. Simultaneously, the theoretical dimensions of each evacuation platform slab can be derived, facilitating the construction unit to organize and categorize slab types, reducing the number of formwork sets required for each slab. Specifically, the construction unit, based on the theoretical calculation values ​​of slab dimensions provided in the evacuation platform layout data table and combined with the needs of on-site formwork fabrication, merges and rounds slabs with similar dimensions. Because the clearance at each point is precisely calculated, the possibility of evacuation platform slab encroachment on clearances is reduced later, minimizing on-site cutting and modification work.

[0027] Furthermore, after step S9, the method further includes: S11. For evacuation platform sections where it is difficult to determine whether they encroach on the boundary, and based on the on-site measurement data, generate an actual evacuation platform layout plan according to step S9. Then compare it with the theoretical evacuation platform layout plan generated in S9 to determine whether the on-site evacuation platform slabs encroach on the boundary and determine the adjustment method. The on-site measurement data includes: the coordinates of the column center and the distances C1 and C2 from the column center to the left and right ends.

[0028] In summary, this embodiment has the following beneficial effects: 1. Based on the route file, structural span data table, superelevation value, and clearance value, the system automatically calculates the position of each column of the evacuation platform. During the construction of the main structure, it provides the accurate coordinates of the evacuation platform columns, reducing the probability of errors in column pre-embedding and improving the construction accuracy of the columns.

[0029] 2. The system automatically calculates the dimensions of each evacuation platform slab, eliminating the need to measure on-site to determine the type and size of the slab, which greatly reduces the workload of on-site measurement. 3. Avoid encroachment on the evacuation platform to reduce the huge workload caused by subsequent adjustments, cutting, and rectification.
