Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular to a positioning device and a positioning method for a suspension bridge anchoring system. Background Art

[0002] In the anchoring construction of suspension bridges, prestressed anchoring systems are often used to anchor the main cables. The prestressed pipes and anchor pads of the prestressed anchoring system are pre-buried and installed in the anchor blocks at a preset inclination angle (the prestressed pipes and anchor pads are arranged inclined upward). After the anchor blocks are cast and formed, the steel strands connected to the main cables are passed through the prestressed pipes and tensioned and installed on the anchor pads. Finally, concrete is poured into the prestressed pipes to seal them. It can be seen that the installation angles of the prestressed pipes and anchor pads directly determine the force direction of the steel strands. If the installation angle deviates from the preset inclination angle, the prestressing direction of the steel strands will deviate from the design direction, affecting the force distribution of key components such as the main beam and main cable. It may cause local stress concentration in the suspension bridge, thereby weakening the overall bearing capacity of the structure. Therefore, the accuracy of the installation position of the prestressed pipes and anchor pads is crucial.

[0003] In the prior art, when installing a prestressed pipe, a bracket is set at the preset position of the prestressed pipe, and the prestressed pipe is placed on the bracket. Then, a positioning frame is fixed at the upper end of the prestressed pipe. The positioning frame is provided with three observation points, located at the top and left and right sides of the prestressed pipe. The coordinates of the three observation points are then observed and the coordinates of the center point of the prestressed pipe at this time are deduced and calculated based on them. By comparing with the preset center point coordinates, the installation position of the prestressed pipe can be adjusted so that the center point coordinates of the upper end of the prestressed pipe are consistent with the preset center point coordinates. In actual construction, the prestressed pipe is usually composed of multiple pipes spliced ​​together, and multiple pipes need to be installed and spliced ​​one by one to form the prestressed pipe. If the above installation method is used, it only measures and adjusts the coordinates of the center point of the upper port of the installed prestressed pipe, and cannot control the spatial angular connection between the pipes. Even if the coordinates of a single pipe section are correct, the overall axis after splicing may still have angular deviations, which can easily cause pipe installation errors. The prestressed pipe installation direction will differ from the preset installation direction, causing the prestressing direction of the steel strand to deviate from the designed direction, affecting the force distribution of key components of the suspension bridge (such as the main beam and main cable). In addition, the coordinates of the center point of the prestressed pipe are obtained through indirect calculation, which is easily affected by the precision of the positioning frame and the installation position, resulting in large errors. Summary of the Invention

[0004] The purpose of the present invention is to provide a positioning device and a positioning method for a suspension bridge anchoring system, which can improve installation accuracy, control the installation direction of the pipeline, effectively avoid angular deviation during pipeline splicing, prevent the prestressing direction of the steel strand from deviating from the design direction, avoid affecting the force distribution of key components of the suspension bridge, and reduce installation errors.

[0055] Example 1

[0056] This embodiment provides a positioning device, such as Figures 1 to 7 As shown, using the positioning device to position the anchoring system 1 of the suspension bridge can improve installation accuracy, control the installation direction of the pipe 122, effectively avoid angular deviation when splicing the pipe 122, reduce the installation error of the pipe 122, and also reduce the workload of the staff.

[0057] like Figure 3 As shown, the anchoring system 1 of the suspension bridge includes a first anchor plate 11, a prestressed tube 12, and a second anchor plate 13, which are spliced ​​in sequence. The first anchor plate 11 and the second anchor plate 13 are both provided with mounting holes, and the inner cavity of the prestressed tube 12 is directly opposite to the mounting holes. The prestressed tube 12 includes a plurality of sleeves 121 and a plurality of pipes 122. A sleeve 121 is used to splice between two adjacent pipes 122, between a pipe 122 and the first anchor plate 11, and between a pipe 122 and the second anchor plate 13. The inner diameter of the mounting hole is the same as the inner diameter of the sleeve 121. It can be seen that the multiple pipes 122 are spliced ​​into one piece through the multiple sleeves 121. At the same time, a sleeve 121 is spliced ​​at the mouth of the pipe 122 at both ends, thereby forming the prestressed tube 12. The two sleeves 121 at both ends are spliced ​​with the first anchor plate 11 and the second anchor plate 13 respectively.

[0058] like Figures 1 to 3 As shown, the positioning device is configured as an anchoring system 1 for positioning a suspension bridge, and the positioning device includes a positioning base 2, a prediction member 3 and a target member 4. The cross-sectional area of ​​the positioning base 2 is the same as the cross-sectional area of ​​the mounting hole. The positioning base 2 can be selectively buckled into the pipe mouth of the sleeve 121 or the mounting hole so that the centroid of the positioning base 2 is collinear with the centroid of the sleeve 121 or the centroid of the mounting hole. A through hole 121 is provided at the centroid of the positioning base 2. The prediction member 3 is selectively connected to the positioning base 2, and the prediction member 3 is vertically connected to the centroid of the positioning base 2. The length of the prediction member 3 is the same as the length of the pipe 122, and a socket 321 is provided at the end of the prediction member 3 facing away from the positioning base 2. The target member 4 can be selectively inserted into the through hole 121 or the socket 321.

[0059] When positioning the anchoring system 1, first vertically splice any one of the sleeves 121 with the first anchor plate 11 so that the centroids of the sleeve 121 and the first anchor plate 11 are collinear, and at the same time vertically splice the other sleeve 121 with the second anchor plate 13 so that the centroids of the sleeve 121 and the second anchor plate 13 are collinear. Then, according to the preset installation direction of the prestressed pipe 12, the first anchor plate 11 is installed on the anchoring template, and the sleeve 121 spliced ​​with the first anchor plate 11 is tilted upward, and the sleeve 121 pipe mouth faces the main cable of the suspension bridge, and then the positioning The base 2 is buckled on the pipe mouth of the sleeve 121 on the first anchor plate 11, and the target part 4 is inserted into the through hole 121. The coordinates of the target part 4 at this time are measured using a measuring device. The coordinates of the target part 4 at this time are the actual center point coordinates of the pipe mouth of the sleeve 121 at this time. The coordinates of the target part 4 at this time are recorded as the first coordinates. If the first coordinates are inconsistent with the preset center point coordinates of the pipe mouth of the sleeve 121, the installation position of the first anchor plate 11 is adjusted until the measured first coordinates are consistent with the preset center point coordinates of the pipe mouth of the sleeve 121, thereby completing the first coordinate adjustment.

[0060] After completing the first coordinate adjustment, the positioning base 2 and the target part 4 are disassembled and removed, and then the prediction part 3 and the positioning base 2 are connected, and the target part 4 is inserted into the socket 321. The positioning base 2 is buckled on the pipe mouth of the sleeve 121 on the first anchor plate 11 again, and the coordinates of the target part 4 at this time are measured and recorded as the second coordinates. The second coordinates are the center point coordinates of the pipe mouth of the pipe 122 to be spliced ​​with the sleeve 121. The second coordinates are compared to see whether they are the theoretical coordinates of the pipe mouth of the pipe 122 to be spliced ​​with the sleeve 121. If the two are inconsistent, the installation position of the first anchor plate 11 is adjusted until the measured second coordinates are consistent with the theoretical coordinates, thereby completing the second coordinate adjustment. This adjustment is the initial adjustment of the center point coordinates of the pipe mouth of the pipe 122 to be spliced ​​with the sleeve 121, as well as the prediction of the direction of the pipe 122.

[0061] After completing the second coordinate adjustment, the positioning base 2, the prediction part 3 and the target part 4 are disassembled and removed, and a pipe 122 and another new sleeve 121 are spliced ​​on the sleeve 121, and then the above operation is repeated until all pipes 122 are spliced. The sleeve 121 connected to the second anchor plate 13 is spliced ​​with the last pipe 122, and then the positioning base 2 is buckled into the mounting hole groove of the second anchor plate 13, and the target part 4 is inserted into the through hole 1 21. The coordinates of the target part 4 at this time are measured and recorded as the third coordinates. The third coordinates of the target part 4 are compared with the preset center point coordinates of the second anchor plate 13. If the two are inconsistent, the installation position of the first anchor plate 11 is adjusted until the measured second coordinates are consistent with the theoretical coordinates, thereby completing the third coordinate adjustment. This adjustment is a secondary adjustment of the center point coordinates of the installed pipe 122. Finally, the positioning base 2 and the target part 4 are disassembled to complete the positioning work of the anchoring system 1.

[0062] By buckling the positioning base 2 on the pipe mouth of the installed sleeve 121 and inserting the target part 4, the installation position of the installed sleeve 121 can be adjusted to ensure that it is consistent with the preset installation position. After adjusting the position of the sleeve 121, the prediction part 3 is vertically connected to the centroid of the positioning base 2, and the target part 4 is inserted on the prediction part 3. Then, the positioning base 2 is buckled on the pipe mouth of the sleeve 121 again, and the position of the installed structure can be adjusted again to improve the installation accuracy. At the same time, the prediction part 3 can provide installation guidance and directly give the theoretical installation direction of the pipe 122 to be spliced, ensuring the accuracy of the splicing direction of the pipe 122 and reducing cumulative deviations. By controlling the spatial direction of the prediction part 3, the staff can control the installation direction of the pipe 122, effectively avoiding the angle deviation when the pipe 122 is spliced, preventing the prestressing direction of the steel strand from deviating from the design direction, and avoiding affecting the force distribution of the key components of the suspension bridge. In addition, the center point coordinates of the pipe opening of the sleeve 121 and the pipe opening of the pipe 122 are directly measured, which can reduce installation errors.

[0063] Exemplarily, the target element 4 includes a prism insert, and the measuring device includes a total station.

[0064] In this embodiment, when the first anchor plate 11 is mounted on the anchor form, bolts may be used to penetrate the first anchor plate 11 and the anchor form and be threadedly connected with nuts. In other embodiments, when the first anchor plate 11 is mounted on the anchor form, the first anchor plate 11 may be first attached to the anchor form, a snap connector may be provided on one of the first anchor plate 11 and the anchor form, and then the snap connector may be snapped onto the other. This is not a limitation herein.

[0065] Alternatively, as Figure 2 、 Figure 4 and Figure 5As shown, the prediction member 3 includes a vertically connected mounting base 31 and a prediction rod 32. The centroid of the mounting base 31 and the centroid of the prediction rod 32 are collinear. The mounting base 31 can be connected to the positioning base 2 so that the centroid of the mounting base 31 coincides with the centroid of the positioning base 2. The prediction rod 32 is adjustable in length along the axial direction, and a socket 321 is provided on the end of the prediction rod 32 facing away from the mounting base 31. When predicting the installation direction of the next pipe 122 to be spliced, it is necessary to connect the prediction part 3 vertically to the centroid of the positioning base 2. By connecting the mounting base 31 to the positioning base 2, the connection between the prediction part 3 and the positioning base 2 can be achieved, and the prediction rod 32 is perpendicular to the mounting base 31. Therefore, the prediction rod 32 is also perpendicular to the positioning base 2. If the positioning base 2 is buckled on the pipe mouth of the sleeve 121, the inclination direction of the prediction rod 32 is the predicted installation direction of the next pipe 122 to be spliced. The staff can directly observe and judge whether the predicted installation direction of the pipe 122 is consistent with the designed installation direction of the pipe 122. At the same time, the target can also be The target part 4 is inserted into the socket 321 on the prediction rod 32, and the coordinates of the target part 4 are measured to see if they match the preset center point coordinates of the pipe 122 to be spliced. If the predicted installation direction is inconsistent with the designed installation direction of the pipe 122, or if the measured coordinates of the target part 4 are inconsistent with the preset center point coordinates, they can be adjusted by adjusting the installation position of the first anchor plate 11. Adjusting the spatial point coordinates and spatial direction can more accurately control the installation direction of the pipe 122, effectively avoid angular deviation when splicing the pipe 122, prevent the prestressing direction of the steel strand from deviating from the design direction, and avoid affecting the force distribution of the key components of the suspension bridge. In addition, the length of the prediction rod 32 is adjustable along the axial direction, and can be used to predict the installation direction of pipes 122 of different lengths, with strong versatility.

[0066] Optionally, the positioning device also includes a connector and a fastener. The connector is positioned on the side of the mounting base 31 facing away from the prediction rod 32 and is collinear with the centroid of the mounting base 31. The connector passes through through-hole 1 21 and is threadedly connected to the fastener. To connect the mounting base 31 and the positioning base 2, simply stack them, insert the connector through through-hole 1 21, and then thread the connector into the fastener. This provides a simple structure and convenient operation.

[0067] Exemplarily, the connector includes a screw and the fastener includes a fastening nut.

[0068] Optionally, the prediction rod 32 includes a first rod body and a second rod body. One end of the first rod body is connected to the mounting base 31, and the other end is hollow. One end of the second rod body extends into the first rod body and is threadedly connected to the inner wall of the first rod body. A socket 321 is provided at the end of the second rod body away from the first rod body. When the length of the pipe 122 to be spliced ​​is shorter, the required length of the prediction rod 32 is shorter. The second rod body can be screwed into the first rod body to reduce the overall length of the prediction rod 32. When the length of the pipe 122 to be spliced ​​is longer, part of the second rod body can be screwed out of the first rod body to increase the overall length of the prediction rod 32. The adjustment method is simple and easy to operate.

[0069] In some embodiments, the positioning device further includes a limiting plug-in, and the prediction rod 32 includes a third rod body and a fourth rod body. One end of the third rod body is connected to the mounting base 31, and the other end of the third rod body is hollow inside and has a plurality of through holes 2 spaced apart along the axial direction. One end of the fourth rod body has a plurality of through holes 3 spaced apart along the axial direction and extends into the third rod body. The limiting plug-in is inserted into through holes 2 and 3, and the other end of the fourth rod body is provided with a socket 321. When it is necessary to increase or decrease the length of the prediction rod 32, it is only necessary to pull out part of the second rod body or extend it into the first rod body, and then insert the limiting plug-in into through holes 2 and 3. The structure is simple and the operation is simple.

[0070] Alternatively, as Figure 1 、 Figure 3 and Figure 6 As shown, the positioning device further includes at least one lifting lug 5, which is provided on the positioning base 2. When the positioning base 2 needs to be buckled into the pipe mouth of the sleeve 121 or buckled into the mounting hole groove, the staff can buckle the positioning base 2 into the pipe mouth of the sleeve 121 or the mounting hole groove by holding the lifting lug 5, and can maintain the positioning base 2 in a stable state in the pipe mouth of the sleeve 121 or the mounting hole groove by supporting the lifting lug 5. Moreover, when the positioning base 2 needs to be disassembled, it can also be disassembled by holding the lifting lug 5. By providing the lifting lug 5, a force application basis can be provided for the staff, and the structure is simple and easy to operate.

[0071] In this embodiment, two lifting lugs 5 are provided. In other embodiments, one or more lifting lugs 5 may be provided according to actual needs, which is not limited here.

[0072] Alternatively, as Figure 1 、 Figure 3 and Figure 7As shown, the positioning base 2 has a circumferentially protruding retaining projection 6 on the side facing away from the prediction element 3. The retaining projection 6 can be selectively retained within the inner cavity of the sleeve 121 or within the mounting slot. The provision of the retaining projection 6 ensures that the positioning base 2 is stably secured within the sleeve 121 or within the mounting slot, preventing measurement errors caused by movement of the positioning base 2 during measurement and improving the accuracy of the measurement results.

[0073] Alternatively, as Figure 7 As shown, a reinforcement structure 7 is provided on the side of the positioning base 2 facing away from the prediction member 3. By providing the reinforcement structure 7, the strength of the positioning base 2 can be enhanced, measurement errors caused by deformation of the positioning base 2 can be prevented, and the accuracy of the measurement results can be ensured.

[0091] By buckling the positioning base 2 on the pipe mouth of the installed sleeve 121 and inserting the target part 4, the installation position of the installed sleeve 121 can be adjusted to ensure that it is consistent with the preset installation position. After adjusting the position of the sleeve 121, the prediction part 3 is vertically connected to the centroid of the positioning base 2, and the target part 4 is inserted on the prediction part 3. Then, the positioning base 2 is buckled on the pipe mouth of the sleeve 121 again, and the position of the installed structure can be adjusted again to improve the installation accuracy. At the same time, the prediction part 3 can provide installation guidance and directly give the theoretical installation direction of the pipe 122 to be spliced, ensuring the accuracy of the splicing direction of the pipe 122 and reducing cumulative deviations. By controlling the spatial direction of the prediction part 3, the staff can control the installation direction of the pipe 122, effectively avoiding the angle deviation when the pipe 122 is spliced, preventing the prestressing direction of the steel strand from deviating from the design direction, and avoiding affecting the force distribution of the key components of the suspension bridge. In addition, the center point coordinates of the pipe opening of the sleeve 121 and the pipe opening of the pipe 122 are directly measured, which can reduce installation errors.
