Description

Technical Field

[0001] This invention relates to the field of hydraulic engineering drawing, and more specifically, to a method, equipment, and medium for generating drawings of a continuous rigid frame aqueduct. Background Technology

[0002] Aqueducts are key control projects in water conservancy infrastructure construction, and modern water conservancy projects place even higher demands on them. With the rapid development of national water conservancy projects, the demand for ultra-long-span water conveyance aqueducts is constantly increasing, especially in long-distance above-ground water conveyance aqueduct projects, where large-span aqueducts are preferred when crossing deep ditches, wide rivers, or important transportation facilities. Continuous rigid frame stacked box girder aqueducts, with their high performance, low investment, and easy maintenance, have become a commonly used structural type for large-span and extra-large-span aqueduct bridges in recent years.

[0003] Currently, very few large-span continuous rigid frame aqueducts have been constructed. The existing methods for drawing drawings of continuous rigid frame aqueducts are basically done manually, which results in low drawing efficiency and poor drawing quality. Summary of the Invention

[0004] The purpose of this invention is to provide a method, equipment, and medium for generating drawings of continuous rigid frame aqueducts, which solves the problems of low drawing efficiency and poor drawing quality of current continuous rigid frame aqueduct drawings.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] In a first aspect, the present invention provides a method for generating drawings of a continuous rigid frame aqueduct, the method comprising:

[0007] Obtain parameter information and length information of each segment of the continuous rigid frame aqueduct;

[0008] Based on the parameter information and the length information of each segment, a general structural diagram of the continuous rigid frame aqueduct body is drawn.

[0009] Obtain the first information of the web steel strands, top plate steel strands and bottom plate steel strands, calculate the first coordinates of each of the web steel strands, top plate steel strands and bottom plate steel strands based on the first information, and draw the longitudinal prestressed steel strand diagram on the general structural diagram according to the first coordinates.

[0010] Second information about the transverse steel strands, vertical steel strands, and circumferential steel strands is obtained. Based on the second information and the length information of each segment, the second coordinates of the transverse steel strands, vertical steel strands, and circumferential steel strands are determined. Based on the second coordinates, the prestressed steel strand diagrams of the transverse steel strands, vertical steel strands, and circumferential steel strands are drawn on the general structural diagram respectively.

[0011] Obtain the arrangement parameters of longitudinal reinforcement, transverse reinforcement and stirrups, and draw the structural reinforcement diagram of longitudinal reinforcement, transverse reinforcement and stirrups on the general construction drawing according to the arrangement parameters and the length information of each segment.

[0012] In one implementation, the method further includes:

[0013] Based on the first coordinate, sections are constructed one by one from the left end to the right end of the trough at equal intervals, and the minimum spacing between adjacent steel strands at each section is calculated.

[0014] The minimum spacing between adjacent steel strands at each cross section is compared with a preset minimum spacing threshold. Based on the comparison result, it is determined whether adjacent steel strands at each cross section collide. If a collision occurs, the minimum spacing is marked on the longitudinal prestressed steel strand cross section diagram, and the collision location of the steel strands is drawn on the longitudinal prestressed steel strand diagram.

Based on the inner and outer contour coordinates of the single-box and stacked-box standard sections, the single-box and stacked-box standard section diagrams of the continuous rigid frame aqueduct are drawn.

[0022] When the longitudinal coordinate values ​​of each segment are greater than the coordinates of the boundary point between the single box and the stacked box, the inner and outer contour coordinates of the cross section of each segment of the single box are calculated based on the thickness of the top plate, bottom plate and web plate of the single box segment, the thickness of the cantilever end, the thickness of the cantilever root, the width of the top plate and the inner contour coordinates of the water passage section. The cross section diagram of the single box segment is drawn based on the inner and outer contour coordinates of the single box section and the standard cross section shape of the single box.

[0023] When the longitudinal coordinate values ​​of each segment are less than or equal to the coordinates of the boundary point between the single box and the stacked box, the inner and outer contour coordinates of the cross section of each segment of the stacked box are calculated based on the thickness of the top plate, bottom plate and web plate, the thickness of the cantilever end, the thickness of the cantilever root, the width of the top plate, the inner contour coordinates of the water passage section, the thickness of the middle partition plate, and the inner contour coordinates of the lower box of the stacked box.

[0047] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a method for generating drawings of a continuous rigid frame aqueduct body according to an embodiment of the present invention, as shown below. Figure 1 As shown, the method includes:

[0048] S101, obtain parameter information and length information of each segment of the continuous rigid frame aqueduct.

[0049] In this embodiment, the parameter information of the continuous rigid frame aqueduct is mainly divided into longitudinal information, transverse information, and standard section information. The parameter information includes the starting and ending coordinates of the beam height section, the starting and ending coordinates of the curved section, the starting and ending coordinates of the straight section, the starting and ending thickness of the bottom plate transition section, the starting and ending coordinates of the inner edge of the web, the starting and ending thickness of the web transition section, the length and thickness of the diaphragm, the width and thickness of the beam top, the thickness of the cantilever end, the thickness of the cantilever root, the inner contour height of the water passage section, the upper chamfer size and the lower chamfer size, and the chamfer size of the stacked box type.

[0050] For example, the longitudinal information of a continuous rigid frame aqueduct includes the starting coordinates P1(0, Z1) and ending coordinates P2(X2, Z1) of the contour section, the starting coordinates P2(X2, Z1) and ending coordinates Pn-1(Xn-1, Zn-1) of the curved section, the starting coordinates Pn-1(Xn-1, Zn-1) and ending coordinates Pn(Xn, Zn-1) of the straight section, the arrangement spacing of the aqueduct spans (e.g., (67+120+67)m), the degree of the parabola at the bottom of the beam (e.g., 1.8), and the origin of the coordinate system (with the center of the aqueduct pier as the origin).

[0051] It is understandable that the start and end coordinates include the start coordinates and the end coordinates. Secondly, the longitudinal information refers to the coordinates in the XZ plane of the three-dimensional coordinate system. The transverse information includes the beam top width B, the cantilever end thickness Bt1, the cantilever root thickness Bt2, the chamfer dimension A×B (length×height) on the water-crossing section, and the lower chamfer dimension R. The length information of each segment is Li(6+4×3+6×3.5+5×4)m. It should be noted that a segment is a beam segment of a continuous rigid frame aqueduct. Since a continuous rigid frame aqueduct is composed of multiple beam segments, for example, the length information Li(6+4×3+6×3.5+5×4) provided in this embodiment consists of one 6m long beam segment, four 3m long beam segments, six 3.5m long beam segments, and five 4m long beam segments.

[0052] Information can be obtained by reading an Excel file of structural parameters or by manually entering them.

[0053] S102. Draw a general structural diagram of the continuous rigid frame aqueduct body based on the parameter information and the length information of each segment.

[0054] In this embodiment, generally speaking, the general structural drawing includes the bottom edge line of the beam, the inner edge line of the bottom plate, the inner edge line of the web, the outer edge line of the web, and the standard cross-sectional view of the continuous rigid frame aqueduct. The required engineering drawings also need to be divided into elevation views and cross-sectional views, such as the line distribution of an elevation, which is common knowledge in this technical field.

[0055] Based on the parameter information and the length information of each segment, a general structural diagram of the continuous rigid frame aqueduct body is drawn, as follows:

[0059] In this embodiment, with the center of the pier as the origin, the thickness of the bottom plate of the beam at the starting point of the curved segment is d1 (which is the thickness of the bottom plate at the beginning and end of the beam height equalization segment), and the thickness of the bottom plate at the end of the curved segment is dn (which is the thickness of the bottom plate at the beginning and end of the straight segment). Based on the length information of each segment, the thickness of the bottom plate at each segment division of the curved segment is calculated. By calculating the theoretical thickness of the base plate at each segment of the curve segment, the inner edge line of the base plate of the curve segment is drawn.

[0060] S1023. Based on the length of the partition plate, determine the coordinates of the dividing point between the single-box section and the stacked-box section. When the longitudinal coordinate value of each section is greater than zero and less than the longitudinal coordinate value of the dividing point, the bottom plate thickness of the stacked-box section is the bottom plate thickness of each section. When the longitudinal coordinate value of each section is greater than the longitudinal coordinate value of the dividing point and less than or equal to the longitudinal coordinate value of the end point of the straight section, calculate the bottom plate thickness of the single-box section based on the height of the trough beam, the height of the inner contour of the water passage section, and the thickness of the top plate of the trough.

[0061] In this embodiment, the center of the trough pier is taken as the origin, and the length L of the diaphragm is used as the reference point. 中 That is, the X coordinates of the dividing point between the single-box section and the stacked-box section. 中 Then input the thickness h of the middle partition. 中 The height h of the inner contour of the water passage section 水 The thickness of the top plate of the tank body is Dt; therefore, when the segment coordinates Xi∈(0,X) 中 When the thickness of the bottom plate of the stacked box segment is di, it is the thickness calculated in step S1022; when the segment coordinates Xi∈(X 中 When [Xn] is used, the bottom plate thickness di of a single box section is calculated as: beam height Zi - top plate thickness of the trough body Dt - inner contour height h of the water passage section.水 This step corrects the inner edge line of the bottom plate of the single-box section and draws the partition plate of the stacking area.

[0062] S1024. Based on the thickness of the starting and ending points of the web segment, calculate the web thickness at each segmental dividing line. Then, combined with the starting and ending coordinates of the inner edge line of the web, calculate the outer edge line coordinates of any segmental dividing line. Draw the inner and outer edge lines of the web using the coordinates of the inner and outer edge lines of the web.

[0063] In this embodiment, taking the center of the pier as the origin, the starting coordinates PM1(X1, Y1) and ending coordinates PM2(X2, Y2) of the inner edge line of the equal-thickness section web are input respectively; the starting coordinates PM2(X2, Y2) and ending coordinates PMn(Xn, Yn) of the inner edge line of the changing section are input respectively; then the starting thickness Ft1 (thickness of the equal-thickness section web) and the ending thickness Ftn of the changing section are input, and the web thickness of the changing section is calculated. Based on the coordinates of the inner edge of the web and the web thickness, the coordinates of the outer edge of the web are calculated, and the inner and outer edge diagrams of the web are drawn using the coordinates of the inner and outer edges.

[0064] S1025. Based on the beam top width, cantilever end thickness, cantilever root thickness, chamfer dimensions on the water passage section and the lower chamfer dimensions on the water passage section, and combined with the beam bottom edge line, trough top plate thickness, water passage section inner contour height, single box / stacked box bottom plate thickness, web inner edge line and web thickness, and stacked box lower box chamfer dimensions, calculate the inner and outer contour coordinates of the single box standard section and the stacked box standard section respectively. Based on the inner and outer contour coordinates of the single box and stacked box standard sections, draw the single box and stacked box standard section diagrams of the continuous rigid frame trough.

[0065] In this embodiment, the center of the top of the aqueduct box girder is taken as the origin of the coordinate system. The top width B of the girder, the thickness Bt1 of the cantilever end, the thickness Bt2 of the cantilever root, the chamfer dimensions A×B (length×height) and the lower chamfer dimensions R on the water passage section are input respectively. Then, the bottom curve Zi of the girder, the thickness Dt of the top plate, and the inner contour height h of the water passage section are calculated above. 水 Given the inner edge line Yi of the web and the web thickness Fti, the inner and outer contour coordinates of the standard section of a single box can be obtained sequentially, and the standard section diagram of the single box of the continuous rigid frame aqueduct can be drawn.

The top width B of the girder, the thickness Bt1 of the cantilever end, the thickness Bt2 of the cantilever root, the chamfer dimensions A×B (length×height) and the lower chamfer dimensions R on the water passage section are input respectively. Then, the bottom curve Zi of the girder, the thickness Dt of the top plate, and the inner contour height h of the water passage section are calculated above.水 The inner and outer contour coordinates of the standard cross-section of the stacked box can be obtained by taking the base plate thickness di, the inner edge line Yi of the web, the web thickness Fti, and the chamfer dimensions C×D (length×height) of the stacked box, and then drawing the quasi-cross-section diagram of the stacked box of the continuous rigid frame aqueduct.

[0070] S1026 When the longitudinal coordinate values ​​of each segment are greater than the coordinates of the boundary point between the single box and the stacked box, the inner and outer contour coordinates of the cross section of each segment of the single box are calculated based on the thickness of the top plate, bottom plate and web plate of the single box segment, the thickness of the cantilever end, the thickness of the cantilever root, the width of the top plate and the inner contour height of the water passage section. The cross section diagram of the single box segment is drawn based on the inner and outer contour coordinates of the single box section and the standard cross section shape of the single box.

[0071] S1027 When the longitudinal coordinate values ​​of each segment are less than or equal to the coordinates of the boundary point between the single box and the stacked box, the inner and outer contour coordinates of the cross section of each segment of the stacked box are calculated based on the thickness of the top plate, bottom plate and web plate, the thickness of the cantilever end, the thickness of the cantilever root, the width of the top plate, the height of the inner contour of the water passage section, the thickness of the middle partition plate, and the inner contour coordinates of the lower box of the stacked box. The cross section diagram of the stacked box segment is drawn based on the inner and outer contour coordinates of the stacked box section and the standard cross section shape of the stacked box.

[0072] In summary, by combining steps S1021-S1027 provided in this embodiment, the three-dimensional coordinates of the aqueduct box girder can be obtained, and the general structural drawings (elevation view, plan view, and cross-section view) of the continuous rigid frame aqueduct body can be completed.

[0074] In this embodiment, the first information of the web steel strand includes the vertical bending information and the horizontal bending information of the web steel strand. The vertical bending information of the web steel strand includes a first distance and a second distance from the top edge of the top plate of the trough, a third distance from the anchoring surface of the web steel strand to the cantilevered segment of the steel strand, the vertical inclination angle of the web steel strand, and the vertical bending radius of the web steel strand. The horizontal bending information of the web steel strand includes a fourth distance from the web steel strand to the centerline of the box girder.

[0075] The first information of the top plate steel strand includes the vertical bending information and horizontal bending information of the top plate steel strand. The vertical bending information of the top plate steel strand includes the fifth and sixth distances from the top edge of the box girder top plate, the seventh distance from the anchoring surface of the top plate steel strand to the cantilevered segment of the steel strand, the vertical inclination angle of the steel strand, the anchoring end length in the vertical bending direction, and the vertical bending radius of the top plate steel strand. The horizontal bending information of the top plate steel strand includes the eighth and ninth distances from the top plate steel strand to the center line of the trench, the horizontal bending radius of the top plate steel strand, the anchoring end length in the horizontal bending direction, and the horizontal inclination angle of the steel strand.

[0076] The first information of the bottom plate steel strand includes the vertical bending information and the horizontal bending information of the bottom plate steel strand. The vertical bending information of the bottom plate steel strand includes the tenth distance from the lower edge of the bottom plate of the trench body, the eleventh distance from the upper edge of the bottom plate of the trench body, the twelfth distance from the anchoring surface of the bottom plate steel strand to the steel strand cantilever segment, the anchoring end length in the vertical bending direction, the vertical inclination angle, the vertical bending radius of the bottom plate steel strand, and the thickness of the bottom plate. The horizontal bending information of the bottom plate steel strand includes the thirteenth and fourteenth distances from the center line of the trench body, the horizontal bending radius of the bottom plate steel strand, the anchoring end length in the horizontal bending direction, and the horizontal inclination angle of the steel strand in the horizontal bending direction.

[0077] Specifically, for the longitudinal web tendons Fn (where n is the cantilever segment number), with the centerline of the pier as the coordinate origin, the vertical bending information is first input, including the first distance S1 from the top edge of the box girder, the second distance S2 (which can be understood as S1 being the distance from the unbent portion of the longitudinal web tendon to the top edge of the box girder, and S2 being the distance from the lowest bending portion of the longitudinal web tendon to the top edge of the box girder), the third distance Ls from the anchorage surface to each cantilever segment, the tendon inclination angle βs, and the tendon vertical bending radius Rs. Then, the horizontal bending information, i.e., the fourth distance P from the centerline of the box girder, is input.

Based on the second coordinates, draw the prestressed steel strand diagrams of the transverse steel strand, vertical steel strand and circumferential steel strand on the general structural diagram respectively.

[0103] In this embodiment, the second information of the transverse steel strands includes the distances from the anchoring end and tensioning end of the top plate transverse steel strands to the surface of the trough and the distances from the top edge of the trough; the distances from the anchoring end and tensioning end of the middle diaphragm transverse steel strands to the surface of the trough and the distances from the bottom edge of the middle diaphragm; and the distances from the anchoring end and tensioning end of the bottom plate transverse steel strands to the surface of the trough and the distances from the bottom edge of the bottom plate.

[0104] Specifically, the transverse steel strand information is mainly divided into top plate transverse steel strands Cn, middle plate transverse steel strands Zn, and bottom plate transverse steel strands Wn. Using the main pier centerline as the coordinate origin, the arrangement spacing of the top plate transverse steel strands Cn, middle plate transverse steel strands Zn, and bottom plate transverse steel strands Wn for each segment is set according to the length information Li of each segment: Li = dj1 + n × dj2 + dj3 (dj1 is the distance from the right segment line, dj3 is the distance from the left segment line, and dj2 is the steel strand arrangement spacing). Then, the distance dc1 between the anchoring end of the top plate transverse steel strand Cn and the surface of the trench, the distance dc2 between the tensioning end and the surface of the trench, and the steel strand spacing are entered sequentially.

[0105] It is important to understand that the calculation principle for the second coordinate of the transverse, vertical, and circumferential steel strands is the same. Therefore, this embodiment only provides the calculation process for the transverse steel strands. The calculation process for the vertical and circumferential steel strands can be implemented by referring to the calculation process for the transverse steel strands, as follows:

[0106] The calculation method for the start and end control points of the transverse steel strands in the top slab includes: using the length information of each segment as the longitudinal coordinate value of the start and end control points of the transverse steel strands in the top slab; determining the abscissa value of the start control point of the transverse steel strands in the top slab based on the distance between the anchoring end of the transverse steel strands in the top slab and the surface of the trench body and the width of the top beam; determining the abscissa value of the end control point of the transverse steel strands in the top slab based on the width of the top beam and the distance between the tensioning end of the transverse steel strands in the top slab and the surface of the trench body; and determining the longitudinal coordinate value of the end control point of the transverse steel strands in the top slab based on the distance between the transverse steel strands in the top slab and the upper edge of the top slab.

[0107] The calculation method for the start and end control points of the transverse steel strands of the diaphragm includes: using the length information of each segment as the longitudinal coordinate value of the start and end control points of the transverse steel strands of the diaphragm; determining the transverse coordinate value of the start control point of the transverse steel strands of the diaphragm based on the inner edge of the web, the web thickness, and the distance from the anchoring end of the transverse steel strands of the diaphragm to the surface of the trough; determining the transverse coordinate value of the end control point of the transverse steel strands of the diaphragm based on the inner edge of the web, the web thickness, and the distance from the tensioning end of the transverse steel strands of the diaphragm to the surface of the trough; and determining the longitudinal coordinate value of the start and end control points of the transverse steel strands of the diaphragm based on the thickness of the top plate of the trough, the inner contour height of the water passage section, the thickness of the diaphragm, and the distance from the lower edge of the diaphragm.

[0108] The calculation method for the start and end control points of the transverse steel strands in the bottom plate includes: using the length information of each segment as the longitudinal coordinate value of the start and end control points of the transverse steel strands in the bottom plate; determining the transverse coordinate value of the start control point of the diaphragm steel strand based on the inner edge line of the web, the web thickness, and the distance from the anchoring end of the transverse steel strand in the bottom plate to the surface of the trench; determining the transverse coordinate value of the end control point of the diaphragm steel strand based on the inner edge line of the web, the web thickness, and the distance from the tensioning end of the transverse steel strand in the diaphragm to the surface of the trench; and determining the longitudinal coordinate value of the start and end control points of the transverse steel strands in the bottom plate based on the beam height at the position of the transverse steel strands in the bottom plate and the distance from the lower edge of the bottom plate.

[0109] Based on the calculation process described above, the following calculation expression is obtained:

[0111] ;

[0113] ;

[0114] The coordinates (X, Y, Z) of the control points for the transverse steel strand Wn in the base plate.

[0115] .

[0116] The vertical steel strand information is the web vertical strand Sn. Using the main pier centerline as the coordinate origin, the spacing of the web vertical steel strand Sn in each segment is set according to the length information Li of each segment: Li = dj1 + n × dj2 + dj3 (dj1 is the distance from the right segment line, dj3 is the distance from the left segment line, and dj2 is the steel strand spacing). Then, the distances ds1 (anchor end to the trench surface), ds2 (tensioning end to the trench surface), and ts (steel strand to the outer side of the trench web) of the web vertical steel strand Sn are input sequentially. This yields the three-dimensional coordinates (X, Y, Z) of the control points of the vertical steel strands. The three-dimensional parametric information of the vertical steel strands is then calculated, and the three-dimensional curve of the vertical steel strands is plotted. Therefore, the formula for calculating the coordinates (X, Y, Z) of the vertical steel strand Sn anchoring points is: .

[0117] The circumferential steel strand information is the web circumferential steel strand Un. Using the main pier centerline as the coordinate origin, the spacing of the web circumferential steel strand Un in each segment is set according to the beam segment length Li: Li = dj1 + n × dj2 + dj3 (dj1 is the distance from the right segment line, dj3 is the distance from the left segment line, and dj2 is the steel strand spacing). Then, the distance from the tensioning end of the web circumferential steel strand Un to the surface of the trench (ds2) and the distance from the steel strand to the inner side of the trench web (tu) are input sequentially. This yields the three-dimensional coordinates (X, Y, Z) of the control points of the transverse steel strands. The three-dimensional parametric information of the circumferential steel strands is calculated, and the three-dimensional curve of the circumferential steel strands is plotted. Therefore, the formula for calculating the vertical coordinates (X, Y, Z) of the web circumferential steel strand Un is: R is the radius of the cross-section of the water passage.

[0118] Based on the three-dimensional parameterized information of the transverse steel strands Cn of the top plate, Zn of the transverse steel strands of the middle diaphragm, Wn of the transverse steel strands of the bottom plate, Sn of the vertical steel strands of the web plate, and Un of the circumferential steel strands at any position calculated in this embodiment, the transverse, vertical and circumferential prestressed steel strand diagrams are drawn, including the elevation and planar structural diagrams of the transverse, vertical and circumferential steel strands, and the cross-sectional diagrams of the transverse, vertical and circumferential steel strands.

[0121] Specifically, based on the layout parameters provided in this embodiment, the design parameters for the quantity and length of the reinforcing bars are determined. Specifically, the longitudinal reinforcing bar diameter information d is input.纵 The net protective layer thickness *c* of the longitudinal reinforcement is determined. The structural reinforcement drawing is drawn according to the segment length division in step 1. The longitudinal reinforcement lap splice method is single-sided welding. According to the specification requirements, the longitudinal reinforcement extends 70cm beyond the segment length. Therefore, the longitudinal reinforcement length is segment length *Li* + 0.7m. The longitudinal reinforcement spacing *s* is set. The number of longitudinal reinforcements arranged transversely in the top slab is... The base plate is arranged horizontally in a number of... (Where Yi is the distance from the centerline to the inner side of the web, and Fti is the web thickness); the number of longitudinal reinforcement bars arranged vertically in the web is... The longitudinal reinforcement design shall be completed according to the above calculation principles.

[0122] Input the diameter information d of the horizontal reinforcing bars 横 The net protective layer thickness *c* of the transverse reinforcement is determined by dividing the segment length according to step 1 and drawing the structural reinforcement diagram. The longitudinal spacing of the transverse reinforcement is *s*, therefore the number of reinforcement sections is... The length of the transverse reinforcement in the top slab is l 顶 =B-2×c, length of transverse reinforcement in the bottom slab l 底 =Yi+Fti-2×c (where Yi is the distance from the centerline to the inner side of the web, and Fti is the thickness of the web), and complete the transverse reinforcement design according to the above calculation principle.

[0123] Input the diameter information d of the stirrups. 箍 Given the net protective layer thickness *c* of the stirrups, and drawing the structural reinforcement diagram according to the segment length division in step 1, with the stirrups spaced longitudinally at intervals of *s*, the number of stirrups is: Vertical length l of web stirrup reinforcement 竖 =Zi-2×c, transverse length of web stirrups l 横 =Fti-2×c (where Yi is the distance from the inner side of the web to the centerline, and Fti is the web thickness), and complete the stirrup design according to the above calculation principle.

[0124] In summary, the method for generating drawings of a continuous rigid frame aqueduct provided by this invention involves: obtaining parameter information of the continuous rigid frame aqueduct and length information of each segment (beam segment); drawing a general structural diagram of the continuous rigid frame aqueduct body based on the parameter information and length information of each segment; then obtaining first information of the web steel strands, top plate steel strands, and bottom plate steel strands, calculating the first coordinates of each of the web steel strands, top plate steel strands, and bottom plate steel strands based on the first information, and drawing a longitudinal prestressed steel strand diagram on the general structural diagram based on the first coordinates; obtaining second information of the transverse steel strands, vertical steel strands, and circumferential steel strands, determining the second coordinates of the transverse steel strands, vertical steel strands, and circumferential steel strands based on the second information and length information of each segment, and drawing prestressed steel strand diagrams of the transverse steel strands, vertical steel strands, and circumferential steel strands on the general structural diagram based on the second coordinates; obtaining the arrangement parameters of the longitudinal reinforcement, transverse reinforcement, and stirrups, and drawing the structural reinforcement diagram of the longitudinal reinforcement, transverse reinforcement, and stirrups on the general structural diagram according to the arrangement parameters and length information of each segment. In other words, the present invention adopts a unified data model, and changes in the data of the continuous rigid frame aqueduct body will automatically affect the relevant structural drawings. This allows for the automatic extraction of structural parameters to generate drawings, thereby reducing repetitive data input and manual calculations and improving the efficiency and accuracy of drafting work.

[0125] Secondly, the single and double-cell continuous rigid frame aqueducts have complex structures, with multiple types of longitudinal, transverse, and vertical steel strands arranged in an interlaced manner. Traditional manual drafting cannot effectively check the clearance between steel strands, leading to steel strand conflicts or failure to meet code requirements, thus affecting structural quality.

[0127] S202, compare the minimum spacing between adjacent steel strands at each cross section with the preset minimum spacing threshold, and determine whether adjacent steel strands at each cross section collide based on the comparison result. If a collision occurs, mark the minimum spacing on the longitudinal prestressed steel strand cross section diagram and draw the collision position of the steel strand on the longitudinal prestressed steel strand diagram.

[0128] In this embodiment, a minimum longitudinal steel strand spacing warning threshold dmin is set according to design requirements; then, the longitudinal steel strand coordinates are extracted from the longitudinal prestressed steel strand diagram to obtain the longitudinal steel strand coordinate information used; sections are constructed one by one from the left end to the right end of the trench at intervals of 0.5cm, and the minimum spacing between adjacent steel strands at each section is calculated. Based on the input minimum control threshold, collision detection is performed on the spacing between steel strands at different longitudinal sections. When ds≤dmin, a collision warning is determined to have occurred in the steel strands.

[0129] When the calculated minimum spacing ds ≤ dmin between adjacent steel strands, a collision warning is determined, and the collision location of the steel strand is output and plotted on the plan and elevation views of the continuous rigid frame aqueduct. The collision detection results are then clearly checked.
