Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bridge engineering, and in particular to a method and a system for reading plane coordinates of a bridge pile foundation. Background Art
[0002] The foundation is an important structural structure and load-bearing component of the bridge. The construction of the bridge usually starts from the foundation. Pile foundation, as a form of bridge foundation, is widely used in bridge engineering. In actual engineering construction, the accurate layout of the plane coordinates of the pile foundation is the prerequisite for the accurate positioning of the entire bridge on the plane, and it is the basis for the orderly construction of the bridge according to the established goals.
[0003] In highways, especially mountain highways, bridges occupy a large proportion of the entire route, with a large number of piers and pile foundations that may reach tens of thousands. The traditional method of reading the plane coordinates of pile foundations is to draw a two-dimensional pile foundation layout diagram manually in a two-dimensional mapping software, then select the pile foundations one by one in the two-dimensional pile foundation layout diagram, and record the pile foundation coordinates displayed by the two-dimensional mapping software. The specific steps of drawing a two-dimensional pile foundation layout diagram in a two-dimensional mapping software include drawing the center line of the bridge according to the design data to obtain the overall plane layout diagram of the bridge, drawing each pier and the pile foundation inside it according to the relative position relationship between the pile foundation and the pier, and finally drawing each pier and the pile foundation inside it on the center line of the bridge according to the relative position relationship between the pier, especially the center line of the pier and the center line of the bridge to obtain a two-dimensional pile foundation layout diagram, thereby achieving accurate stakeout of the pile foundation. This solution manually takes the plane coordinates of the pile foundation one by one in the plane diagram, which is not only time-consuming and laborious, but also has a high error rate due to the large number of pile foundations.
[0004] Another method is to model the pile foundation in 3D software based on the existing 2D pile foundation layout to obtain a 3D model, and then read the plane coordinates of the pile foundation through the information input in the 3D model during the modeling process, including the relative position relationship between the pile foundation and the pier, the relative position relationship between the center line of the pier and the center line of the bridge, etc. This can greatly improve the accuracy of the pile foundation plane coordinate reading, but it is necessary to model the 2D drawings in 3D software, which is a bit cumbersome and has low work efficiency. Summary of the invention
[0005] The embodiment of the present application provides a method and system for reading the plane coordinates of bridge pile foundations. Based on the existing two-dimensional mapping software, a local coordinate system is constructed at each pier by acquiring a two-dimensional pile foundation layout diagram and corresponding bridge-related information. Combined with the relative position relationship between the pier and the pile foundation inside it, all pile foundations inside each pier are automatically identified and numbered, and the coordinates of all pile foundations are output according to the numbers. The plane coordinates of pile foundations at different positions can be acquired efficiently and accurately in an intelligent manner.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the drawings describe only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0037] Based on the problems existing in the prior art, the present invention proposes a method and system for reading the plane coordinates of bridge pile foundations, including: obtaining a two-dimensional pile foundation layout diagram and corresponding bridge-related information. Constructing a local coordinate system 6 at each intersection 5. Identifying all pile foundations 4 within the range of each pier cap 3, and numbering each pile foundation 4 according to its coordinates in its corresponding local coordinate system 6 to obtain numbering information. According to the numbering information of each pile foundation 4, sequentially obtain the pile foundation plane coordinates of all pile foundations 4 under the overall coordinates of the two-dimensional pile foundation layout diagram. The present application can construct a local coordinate system 6 at each pier by obtaining a two-dimensional pile foundation layout diagram and corresponding bridge-related information, automatically identifying all pile foundations 4 inside each pier and automatically numbering them in combination with the relative position relationship between the pier and the pile foundation 4 inside it, and outputting the coordinates of all pile foundations 4 according to the numbering, avoiding the problems of low efficiency and high error rate in coordinate reading, and realizing intelligent reading of pile foundation plane coordinates.
[0038] like Figure 1 As shown, in a specific embodiment, the above method includes:
[0039] Step S1a, obtaining a two-dimensional pile foundation layout diagram and corresponding bridge-related information, wherein the bridge-related information includes first coordinate information of the intersection 5 of each pier centerline 2 and the bridge centerline 1 and second coordinate information of each pier cap 3 in the overall coordinate system of the two-dimensional pile foundation layout diagram.
[0040] Step S2a: Based on the first coordinate information, a local coordinate system 6 is constructed at each intersection 5, and the two coordinate axes of the local coordinate system 6 coincide with the pier centerline 2 and the bridge centerline 1. Specifically, given the direction of the bridge centerline 1, the intersection 5 of each pier centerline 2 and the line centerline is obtained.
[0041] Step S3a, according to the second coordinate information, identify all pile foundations 4 within the range of each pier cap 3, and number each pile foundation 4 according to its coordinate in the corresponding local coordinate system 6 to obtain numbering information. Specifically, the piers are numbered in the order of the intersections 5 along the centerline 1 of the bridge, and a local coordinate system 6 is established at each intersection 5. The X-axis and Y-axis of the local coordinate system 6 should conform to the distribution law of the pile foundation 4 to facilitate numbering of the pile foundation 4. For example, the pile foundation 4 is distributed along the X-axis of the local coordinate system 6 in the horizontal direction and along the Y-axis of the local coordinate system 6 in the vertical direction. The range of the pier cap 3 is specified by the local coordinate system 6 at the intersection 5, and the pile foundation 4 of the corresponding pier is identified within the range of each pier cap 3, and the pile foundation 4 is numbered according to the coordinate of the pile foundation 4 in the local coordinate system 6 of the pier.
[0042] Step S4a, sequentially obtain the plane coordinates of all pile foundations 4 in the global coordinate system of the two-dimensional pile foundation layout diagram according to the serial number information of each pile foundation 4. Specifically, read the plane coordinates of each pier pile foundation 4 in the global coordinate system according to the serial number sequence of the pile foundation 4.
[0043] In this embodiment, firstly, a pre-drawn two-dimensional pile foundation layout diagram is obtained, and the bridge related information is the image information in the two-dimensional pile foundation layout diagram. The specific steps of drawing the two-dimensional pile foundation layout diagram in the two-dimensional drawing software include drawing the bridge centerline 1 according to the design data to obtain the overall plan layout diagram of the bridge. The plan layout of the pile foundation 4 of each pier of the bridge is calculated according to the load of the bridge superstructure, the geological conditions at the bridge location and the bridge design control conditions, and the pile foundation 4 of each pier is arranged in the overall plan layout diagram of the bridge in the two-dimensional drawing software for accurate layout (that is, according to the relative position relationship between the pile foundation 4 and the pier, each pier and the pile foundation 4 inside it are drawn, and finally, according to the relative position relationship between the pier, especially the pier centerline 2 and the bridge centerline 1, each pier and the pile foundation 4 inside it are drawn on the bridge centerline 1 to obtain the two-dimensional pile foundation layout diagram). The file information of the two-dimensional pile foundation arrangement diagram contains the coordinates of all the pile foundations 4, but the traditional method is either to open the two-dimensional pile foundation arrangement diagram in the display interface of the two-dimensional drawing software, and then manually click on the pile foundation 4 images one by one to obtain the coordinates of each pile foundation 4 in the overall coordinate system, which cannot be exported in batches, or to convert the two-dimensional pile foundation arrangement diagram into a three-dimensional image and then obtain the coordinates of each pile foundation 4, which cannot be exported in batches. The coordinate reading efficiency is low and the error rate is high, and the position and corresponding coordinates of each pile foundation 4 in the pier need to be manually recorded.
[0044] In order to solve these problems, a local coordinate system 6 is constructed at each intersection 5 according to the first coordinate information of each intersection 5, and all pile foundations 4 within the range of each pier cap 3 are identified according to the second coordinate information of each pier cap 3, that is, the range of each pier cap 3, and each pile foundation 4 is numbered according to the coordinates of the corresponding local coordinate system 6 to obtain the numbering information. After all pile foundations 4 are assigned numbering information, the pile foundation plane coordinates of all pile foundations 4 under the overall coordinates are obtained according to the numbering information. The method of obtaining the coordinates after numbering can realize the orderly and efficient acquisition of the pile foundation plane coordinates, and after obtaining, the coordinates of the pile foundation 4 at which pier and position can be clearly obtained. By calculating and integrating the relevant storage information of the pile foundation plane coordinates, the pile foundation plane coordinates can be exported in batches according to the needs of users, greatly improving the efficiency and accuracy of pile foundation plane coordinate reading.
[0045] There is no need to manually point out the plane coordinates of the pile foundation multiple times, and the error rate of manual point-taking of coordinates is eliminated, which greatly improves the reading efficiency and accuracy of the plane coordinates of the pile foundation, and improves the intelligence and accuracy of the reading of the plane coordinates of the pile foundation.
[0046] This application does not need to establish a pile foundation 4 model in three-dimensional software, but directly reads the plane coordinates of the pile foundations at all different positions from the two-dimensional pile foundation layout diagram based on drawing software, thereby improving the efficiency of pile foundation plane coordinate reading.
[0047] like Figure 2 As shown, in another specific embodiment, the above method includes:
[0048] Step S1b, obtaining a two-dimensional pile foundation layout diagram and corresponding bridge-related information, wherein the bridge-related information includes, in the overall coordinate system of the two-dimensional pile foundation layout diagram, first coordinate information of the intersection 5 of each pier centerline 2 and the bridge centerline 1, second coordinate information of each pier cap 3, and third coordinate information of each pile foundation 4.
[0049] Step S2b: construct a local coordinate system 6 at each intersection 5 according to the first coordinate information, wherein two coordinate axes of the local coordinate system 6 coincide with the pier centerline 2 and the bridge centerline 1 respectively.
[0050] Step S3b: According to the second coordinate information, all pile foundations 4 within the range of each pier cap 3 are identified, and each pile foundation 4 is numbered according to its coordinate in the corresponding local coordinate system 6 to obtain numbering information.
[0051] Step S4b: sort the third coordinate information according to the number information of each pile foundation 4 to sequentially obtain the pile foundation plane coordinates of all the pile foundations 4 under the overall coordinates of the two-dimensional pile foundation arrangement diagram.
[0052] In this embodiment, the third coordinate information of all pile foundations 4, that is, the pile foundation plane coordinates of all pile foundations 4 in the global coordinate system, can be obtained first. Then, after numbering, all pile foundation plane coordinates are sorted to avoid data confusion and data errors when obtaining a large number of pile foundation plane coordinates.
[0053] In a preferred embodiment, the first coordinate information also includes the coordinates of the center lines 2 of each pier and the coordinates of the center line 1 of the bridge in the overall coordinate system of the two-dimensional pile foundation arrangement diagram.
[0054] In this embodiment, in the two-dimensional pile foundation arrangement diagram, relative to the overall coordinate system, the distribution of the numerous pile foundations 4 in each pier is not uniformly distributed along the X-axis direction or the Y-axis direction and has no certain rules. Therefore, a local coordinate system 6 with the pier centerline 2 and the bridge centerline 1 as the X-axis and the Y-axis (or with the pier centerline 2 and the bridge centerline 1 as the Y-axis and the X-axis) is constructed within the range of each pier cap 3. Since in each local coordinate system 6, the distribution of the pile foundation 4 is uniformly distributed along the X-axis and the Y-axis of the local coordinate system 6 and has a certain rule, each pile foundation 4 can be numbered according to the distribution rule, thereby marking all the pile foundations 4 and their positions. Then, the corresponding pile foundation plane coordinates are extracted according to the numbering information of the pile foundation 4 at different positions, and all the pile foundation plane coordinates can be obtained comprehensively, efficiently and accurately, freeing people from the repeated work of taking the pile foundation plane coordinate points, eliminating the error rate of manual point taking of coordinates, greatly improving the reading efficiency and accuracy of the pile foundation plane coordinates, and improving the intelligence and accuracy of the pile foundation plane coordinate reading.
[0055] Furthermore, there is no need to establish a pile foundation 4 model in the three-dimensional software, but the plane coordinates of the pile foundation can be directly read in the two-dimensional software, thereby improving the efficiency of reading the plane coordinates of the pile foundation.
[0056] In a preferred embodiment, the above-mentioned numbering of each pile foundation 4 according to its coordinates in its corresponding local coordinate system 6 specifically includes:
[0057] According to the numbering of each pile foundation 4 in its corresponding local coordinate system 6, all pile foundations 4 within the range of all pier caps 3 are numbered in sequence in a cycle from small to large along the Y axis - from small to large along the X axis. It is also possible to cycle from small to large along the X axis - from small to large along the Y axis as needed.
[0058] In this embodiment, according to the relationship between the pile foundation 4 and the bridge pier, the pile foundation 4 inside each bridge pier is numbered according to the size of the coordinate value in the local coordinate system 6, and the numbering is performed according to the rule of first the Y-axis coordinate from small to large, and then the X-axis coordinate from small to large.
[0059] The order of the pile foundation 4 numbering is determined by the direction of the coordinate axis of the local coordinate system 6. The numbering of the pile foundation 4 can be controlled by controlling the direction of the coordinate axis of the local coordinate system 6. The direction of the coordinate axis of the local coordinate system 6 can be adjusted according to user needs to control the order of obtaining and outputting the coordinates of the pile foundation 4.
[0060] In a preferred embodiment, the above-mentioned acquisition of the pile foundation plane coordinates of all pile foundations 4 under the overall coordinates of the two-dimensional pile foundation layout diagram specifically includes:
[0061] According to the preset coordinate accuracy, the pile foundation plane coordinates of all pile foundations 4 under the overall coordinates of the two-dimensional pile foundation arrangement diagram are obtained.
[0062] In this embodiment, if the required coordinate accuracy is not set, the accuracy of the automatically acquired pile foundation plane coordinates may reach 10 or even 20 decimal places, which is far from the accuracy requirement of 3 decimal places (i.e., millimeter level) in actual engineering and does not meet the actual work requirements.
[0063] Therefore, its accuracy is uniformly set to directly obtain the pile foundation plane coordinates of the required accuracy. In this way, the pile foundation plane coordinate data read can directly guide practice, avoid manual modification of data, minimize manual intervention in the calculated plane coordinates, and reduce the probability of error.
[0064] In a preferred embodiment, the numbering information includes the bridge pier to which the pile foundation 4 belongs and the position of the pile foundation 4 relative to the bridge pier.
[0065] In this embodiment, the size range of the pier cap 3 in the local coordinate system 6 is specified to identify the pile foundation 4 within the size range of the cap 3, and the relationship between the pile foundation 4 and the pier is further determined by numbering, so that the plane coordinates of the pile foundation finally output can correspond to its position.
[0066] like Figure 3 to Figure 4 As shown, in a specific embodiment, the plane coordinate reading system of the bridge pile foundation includes a receiving module 1A based on two-dimensional mapping software, a coordinate system construction module 2A, a pile foundation numbering module 3A, and a pile foundation reading module 4A. The plane coordinate reading system of the bridge pile foundation can be a system based on the two-dimensional mapping software, or a system independent of the two-dimensional mapping software and capable of interacting with the two-dimensional mapping software through an interface.
[0067] The receiving module 1A obtains the two-dimensional pile foundation layout diagram and corresponding bridge-related information, which includes the first coordinate information of the intersection 5 of each pier centerline 2 and the bridge centerline 1 and the second coordinate information of each pier cap 3 in the overall coordinate system of the two-dimensional pile foundation layout diagram.
[0068] The coordinate system construction module 2A constructs a local coordinate system 6 at each intersection 5 according to the first coordinate information.
[0069] The pile foundation numbering module 3A identifies all pile foundations 4 within the range of each pier cap 3 according to the second coordinate information, and numbers each pile foundation 4 according to its coordinate in the corresponding local coordinate system 6 to obtain numbering information.
[0070] The pile foundation reading module 4A sequentially obtains the pile foundation plane coordinates of all the pile foundations 4 under the overall coordinates of the two-dimensional pile foundation arrangement diagram according to the serial number information of each pile foundation 4 .
[0071] The reading system of this embodiment is applicable to the above-mentioned reading methods. The plane layout of the pier pile foundation 4 is calculated according to the known conditions, i.e., the design data. The plane layout of the pile foundation 4 is accurately laid out in the overall plane layout of the bridge using two-dimensional mapping software to obtain a two-dimensional pile foundation layout diagram. The plane coordinates of the pile foundation 4 in the overall coordinate system are calculated in the bridge pile foundation plane coordinate reading system. Only two-dimensional mapping software is needed, and the software requirements are low. The calculation and integration of the pile foundation 4 coordinate storage information in the two-dimensional mapping software, i.e., the pile foundation 4 numbering sequence of each pier, automatically reads the corresponding pile foundation plane coordinates in the overall coordinate system in the two-dimensional mapping software, and can batch export the pile foundation plane coordinates according to the user's needs, greatly improving the efficiency and accuracy of pile foundation plane coordinate reading.
[0072] Specifically, the direction of the given bridge centerline 1 is from left to right. The intersection 5 of each pier centerline 2 and the bridge centerline 1 is obtained. The piers are first numbered through each intersection 5 to obtain pier numbers 1# and 2#. A local coordinate system 6 is established at the intersection 5 between the pier centerline 2 and the bridge centerline 1 of pier 1#, whose X-axis coincides with the bridge centerline 1 and the Y-axis coincides with the pier centerline 2. The range of the pier cap 3 (the pier cap 3 is surrounded by four corner points a, b, c, and d) is specified by the local coordinate system 6 at the intersection 5, and the coordinates of the four corner points in the local coordinate system 6 are (-6, -12), (6, -12), (6, 24), and (-6, 24) respectively. All pile foundations 4 within this range are identified and determined by the coordinates of the four corner points a, b, c, and d in the local coordinate system 6, and the determination condition is that the coordinates of the pile foundation 4 in the local coordinates are within the range of these four corner points. The pile foundation 4 is numbered according to its coordinate value in the local coordinate system 6 of the 1# bridge pier, and the pile foundation 4 is numbered from 1 to 44, and the numbering sequence is first the Y-axis coordinate from small to large, and then the X-axis coordinate from small to large. The plane coordinates of the 1# bridge pier pile foundation 4 in the global coordinate system are read in the order of the pile foundation 4 numbers 1 to 44. When reading, the coordinates are retained with the preset 3 significant digits to obtain the significant digits of the pile foundation plane coordinates required by the user.
[0073] The foregoing is merely a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features claimed herein.
