Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge construction measurement, in particular to a method for quickly positioning and measuring a steel anchor beam of a cable-stayed bridge. BACKGROUND

[0002] The steel anchor beam is a key load-bearing structure of a cable-stayed bridge tower, which is usually in the form of a cable pipe, a cuboid steel beam fixed body and a bracket, and is generally located on the upper tower column of the tower. The positioning accuracy requirement is high. Specifically, the allowable deviation of the anchor point and the outlet center point plane of the steel anchor beam is 5mm, and the relative allowable deviation of the anchor point to the outlet center point axis is only 3mm.

[0003] In the traditional positioning and measurement of the steel anchor beam, a measuring tool is generally used to materialize the three-dimensional coordinates of the anchor point and the outlet center point, and the axis of the cable pipe of the steel anchor beam is indirectly measured for positioning. When the construction personnel perform the measurement operation, the pre-prepared entity measuring tool is first installed at the anchor plate and the cable pipe outlet, then the anchor point and the outlet center point of the cable pipe are replaced by the center of the entity component, and the prism is placed on the center of the entity component, and the three-dimensional coordinates of the anchor point and the outlet center point are measured respectively.

[0004] However, the construction personnel need to install the measuring tool, which is a complex process, and multiple measurement personnel need to cooperate with each other in the air to complete the installation. In addition, since the steel anchor beam cable pipe and the measuring tool are both in an inclined state, it is also difficult to install the prism on the inclined measuring tool. Overall, the positioning and measurement of the steel anchor beam is difficult and the operation efficiency is low. SUMMARY

[0005] In view of the defects in the prior art, the purpose of the present application is to provide a method for quickly positioning and measuring a steel anchor beam of a cable-stayed bridge, so as to reduce the difficulty of positioning and measuring the steel anchor beam and improve the efficiency of positioning and measuring the steel anchor beam.

[0008] In a more preferred improvement, the step of selecting more than three points on the steel anchor beam as reference points and measuring first positioning coordinates of the reference points further comprises the following steps: selecting a plurality of checking points on the steel anchor beam other than the reference points; measuring first checking coordinates of the checking points; and obtaining first relative geometric relations of the checking points and the anchoring points and first relative geometric relations of the checking points and the cable path pipe outlet center points; and the step of adjusting the steel anchor beam to the posture according to the positioning deviation values of the second positioning coordinates of the reference points and the theoretical positioning coordinates of the reference points further comprises the following steps: measuring second checking coordinates of the checking points; and checking and correcting the position of the steel anchor beam.

[0009] In a more preferred improvement, the step of measuring first positioning coordinates of the reference points specifically comprises the following steps: calibrating a total station by using a bridge independent coordinate system; and measuring the reference points on the steel anchor beam by using the total station to obtain the first positioning coordinates of the reference points.

[0010] In a more preferred improvement, the step of measuring first checking coordinates of the checking points specifically comprises the following steps: calibrating a total station by using a bridge independent coordinate system; and measuring the checking points on the steel anchor beam by using the total station to obtain the first checking coordinates of the checking points.

[0011] In a more preferred improvement, the step of adjusting the steel anchor beam to the theoretical posture specifically comprises the following steps: placing the steel anchor beam on a processing jig; measuring actual posture coordinates of the two anchoring points and the two cable path pipe outlet center points on the adjustment device by using the total station; comparing a difference between the actual posture coordinates and the theoretical posture coordinates; and adjusting the steel anchor beam to the theoretical posture on the processing jig according to the difference.

[0012] In a more preferred improvement, the step of calibrating the total station specifically comprises the following steps: arranging a plurality of control points in a steel anchor beam measurement area; placing the total station on a known control point; and looking at another known control point.

[0013] In a more preferred improvement, the specific step of measuring the second positioning coordinates of each reference point comprises: setting a total station on the reference point of the tower anchoring area and calibrating the total station; and measuring each reference point using the total station to obtain the second positioning coordinates of each reference point.

[0014] In a more preferred improvement, the specific step of measuring the second checking coordinates of each checking point comprises: setting a total station on the reference point of the tower anchoring area and calibrating the total station; and measuring each checking point using the total station to obtain the second checking coordinates of each checking point.

[0015] In a more preferred improvement, the specific step of checking and correcting the position of the steel anchor beam comprises: calculating the theoretical checking coordinates of each checking point according to the theoretical installation coordinates of the anchoring points of the steel anchor beam and the center points of the cableway pipe outlets, combining the first relative geometric relationship, and correcting the position of the steel anchor beam according to the checking deviation values of the second checking coordinates of each checking point and the theoretical checking coordinates thereof; checking the positioning deviation values of the second positioning coordinates of each reference point and the theoretical positioning coordinates thereof, and correcting the position of the steel anchor beam according to the positioning deviation values until each positioning deviation value and each checking deviation value meet the requirements.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] This application provides an embodiment of a rapid positioning and measurement method for steel anchor beams of cable-stayed bridges, in order to reduce the difficulty of positioning and measuring steel anchor beams and improve the efficiency of positioning and measuring steel anchor beams.

[0026] Combination Figure 1 and Figure 2 This application provides an embodiment of a rapid positioning and measurement method for a steel anchor beam 1 of a cable-stayed bridge, the steps of which include:

[0027] S 1. Adjust the steel anchor beam 1 to be hoisted to its theoretical posture so that it is consistent with the posture when it is erected on the tower column.

[0028] S2. Record the theoretical attitude coordinates of the two anchoring points 4 and the two cableway tube outlet centers of the steel anchor beam 1. Select more than three points on the steel anchor beam 1 as reference points 2, measure the first positioning coordinates of each reference point 2, and obtain the relative geometric relationship between each reference point 2 and the anchoring point 4, as well as the relative geometric relationship between each reference point 2 and the cableway tube outlet center point 5.

[0029] S3. Place the steel anchor beam 1, after adjusting its posture, in the anchorage area. Based on the theoretical installation coordinates of the anchorage point 4 of the steel anchor beam 1 and the center point 5 of the cableway outlet, calculate the theoretical positioning coordinates of each reference point 2 in combination with the relative geometric relationship. Then measure the second positioning coordinates of each reference point 2. Based on the positioning deviation value between the second positioning coordinates of each reference point 2 and its theoretical positioning coordinates, adjust the steel anchor beam 1 to the correct position.

[0030] During steps S1 and S2, the measurement of steel anchor beam 1 was carried out in the processing workshop of steel anchor beam 1. During step S3, steel anchor beam 1 was hoisted to the anchorage area of ​​the tower column of the cable tower.

[0031] Specifically, in combination Figure 1 and Figure 2 The specific implementation steps for adjusting the steel anchor beam 1 to its theoretical position in step S1 include:

[0032] S11. Place the steel anchor beam 1 on the processing fixture.

[0033] S12. Use the bridge's independent coordinate system to calibrate the total station in the machining fixture area.

[0034] S13. Use a total station to measure the actual attitude coordinates of the two anchor points 4 and the two cableway tube outlet center points 5 on the processing jig, and compare the difference between the actual attitude coordinates and the theoretical attitude coordinates; on the processing jig, adjust the steel anchor beam 1 to the theoretical attitude according to the difference.

[0035] For step S11, the machining jig is the machining fixture used to machine the steel anchor beam 1, which facilitates the subsequent adjustment of the posture of the steel anchor beam 1. The machining jig has a definite position in the machining coordinate system (the coordinate system used when machining the steel anchor beam 1). Therefore, when the steel anchor beam 1 is adjusted to its theoretical posture on the machining jig, the two anchoring points 4 and the two cableway tube outlet center points 5 all have definite theoretical machining coordinates in the machining coordinate system.

[0036] In other embodiments, the steel anchor beam 1 can also be placed on other devices that can adjust the posture of the steel anchor beam 1. However, since it is more convenient to position and adjust the steel anchor beam 1 on the processing jig, it is preferred in this application to adjust the posture of the steel anchor beam 1 on the processing jig.

[0037] To facilitate the measurement work of the staff, in step S12, the bridge independent coordinate system is used. Based on the relationship between the processing coordinate system and the bridge independent coordinate system, after coordinate transformation, the theoretical processing coordinates of the two anchor points 4 and the two cableway tube outlet center points 5 in the processing coordinate system are converted into the theoretical attitude coordinates in the bridge independent coordinate system.

[0038] Specifically, in step S12, the specific steps for calibrating the total station in the machining fixture area are as follows:

[0039] S121. Set up multiple control points in the measurement area of ​​steel anchor beam 1, place the total station on one of the known control points, and backsight another known control point.

[0040] After completing step S121, the total station is calibrated. At this point, in step S13, since anchor point 4 and cableway outlet center point 5 are virtual points, when measuring the actual attitude coordinates of anchor point 4 and cableway outlet center point 5, a measuring fixture needs to be installed at the locations of both anchor points 4 and cableway outlet center points 5. This fixture simulates the virtual points, and then a prism is installed on it. The total station is then used to measure the actual attitude coordinates of the two anchor points 4 and cableway outlet center points 5, and the difference between the actual and theoretical attitude coordinates is compared. Next, on the machining jig, the steel anchor beam 1 is adjusted to the theoretical attitude based on the difference.

[0041] In the next step S2, refer to Figure 2 In this embodiment, four reference points 2 were selected on the steel anchor beam 1. In other embodiments, other numbers of points, such as 3, 5, or 6, can be selected on the steel anchor beam 1, as long as they are greater than or equal to 3. To facilitate the measurement of the first positioning coordinates of the four reference points 2, the four reference points 2 are located at the four corners of the top surface of the steel anchor beam 1. In this way, after the workers use punches to mark the points at the four corners of the top surface, it is relatively easy to install prisms at the marked points. After the prisms are installed, the total station used to adjust the theoretical attitude of the steel anchor beam 1 is used to measure the first positioning coordinates of the four reference points 2.

[0042] Since the theoretical attitude coordinates of the two anchor points 4 and the two cableway tube outlet center points 5 have been obtained in step S12, the first positioning coordinates of the four reference points 2 are compared with the theoretical attitude coordinates of the two anchor points 4, and the theoretical attitude coordinates of the two cableway tube outlet center points 5 are compared with the theoretical attitude coordinates of the two reference points 2. This allows us to obtain the relative geometric relationship between each reference point 2 and the anchor point 4, as well as the relative geometric relationship between each reference point 2 and the cableway tube outlet center point 5.

[0043] After completing the above steps, the subsequent step S3 can be performed. Since the designers have theoretical installation coordinates for the two anchor points 4 and the two cableway outlet center points 5 in each anchorage zone, and since the relative geometric relationships between each reference point 2 and the anchor points 4, as well as the relative geometric relationships between each reference point 2 and the cableway outlet center point 5, have been obtained in step S2, the theoretical positioning coordinates of the four reference points 2 can be derived from the theoretical installation coordinates of the two anchor points 4 and the two cableway outlet center points 5, combined with the relative geometric relationships. After the workers use hoisting equipment to hoist the steel anchor beam 1 to the anchorage zone, the second positioning coordinates of each reference point 2 are measured, and the positioning deviation between the second positioning coordinates and the theoretical coordinates of each reference point 2 is calculated. Based on the positioning deviation values, the steel anchor beam 1 is adjusted to its position.

[0044] The specific steps for measuring the second positioning coordinates of each reference point 2 include:

[0045] S31. Set up a total station at the reference point of the tower anchorage area and calibrate the total station. Then use the total station to measure each reference point 2 and obtain the second positioning coordinates of each reference point 2.

[0046] In step S31, the step S311 for calibrating the total station is as follows: set multiple control points in the tower anchorage area, then select one of the control points as the reference point, set the total station on the reference point, and then use the total station to backsight another control point to complete the calibration of the total station.

[0047] After the above steps, the steel anchor beam 1 is positioned and installed. Compared with the existing technology, in the entire process of installing the steel anchor beam 1, the positioning of the anchor point 4 and the center point 5 of the cableway outlet is transformed into the positioning of the reference point 2 on the actual steel anchor beam 1. The selection of the reference point 2 is completed on the ground, which reduces the operation difficulty for construction personnel. In addition, since the reference point 2 is selected on the actual steel anchor beam 1, there is no need to use measuring tools for simulation. A prism can be directly set up at the reference point 2, which reduces the operation steps for construction personnel and reduces the cumulative error in the measurement process. Therefore, this positioning and measurement method reduces the difficulty of positioning and measuring the steel anchor beam 1, improves the efficiency of positioning the steel anchor beam 1, and improves the positioning accuracy of the steel anchor beam 1.

[0048] In the actual construction process, in order to ensure the accuracy of the installation position of steel anchor beam 1, the staff also need to conduct further acceptance and verification of the installed steel anchor beam 1. For this purpose, referring to Figure 2After selecting three or more points as reference points 2 on the steel anchor beam 1 and measuring the first positioning coordinates of each reference point 2, the process includes step S21: selecting several check points 3 outside of the reference points 2 on the steel anchor beam 1, measuring the first check coordinates of each check point 3, and obtaining the first relative geometric relationship between each check point 3 and the anchor point 4, and the first relative geometric relationship between each check point 3 and the center point 5 of the cableway tube outlet. Correspondingly, after adjusting the steel anchor beam 1 to its position based on the positioning deviation value between the second positioning coordinates of each reference point 2 and its theoretical positioning coordinates, the process includes step S32: measuring the second check coordinates of each check point 3, checking and correcting the position of the steel anchor beam 1.

[0049] Specifically, in step S21, one, two, three, or more verification points 3 can be selected. In this embodiment, two verification points 3 are selected, and the two verification points 3 are located at the bottom end of the cableway tube outlet. With this setting, the two verification points 3 are located at the two positions with the longest distance on the steel anchor beam 1, which conforms to the error propagation law of long side correcting short side, ensuring the accuracy of the verification. When measuring the first verification coordinates of each verification point 3, a punch is used to mark the points at the bottom end of the cableway tube outlet where it is easy to install a prism, and then the prism is installed at the two punch points. The measurement of the two verification points 3 is also carried out using a total station, and the total station used is the same total station used when adjusting the theoretical attitude of the steel anchor beam 1.

[0050] In step S32, a total station is used to measure the second verification coordinates of each verification point 3, and the total station used to measure the second positioning coordinates of each reference point 2 is the same total station.

[0051] Specifically, in step S32, the steps for checking and correcting the position of the steel anchor beam 1 are as follows:

[0052] S321. Based on the theoretical installation coordinates of the anchor point 4 of the steel anchor beam 1 and the center point 5 of the cableway outlet, and combined with the first relative geometric relationship, calculate the theoretical verification coordinates of each verification point 3. Based on the verification deviation value between the second verification coordinates of each verification point 3 and its theoretical verification coordinates, correct the position of the steel anchor beam 1.

[0053] S322. Check the positioning deviation values ​​between the second positioning coordinates of each reference point 2 and its theoretical positioning coordinates, and correct the position of the steel anchor beam 1 according to the positioning deviation values ​​until each positioning deviation value and each check deviation value meet the requirements.

[0054] After the staff installed the steel anchor beam 1 using reference point 2, they then used check point 3 to further check the position of the steel anchor beam 1. Combining reference point 2 and check point 3, the staff adjusted the posture of the steel anchor beam 1, making its position more accurate and further improving the positioning measurement accuracy of the steel anchor beam 1.

[0055] The working principle of this embodiment is as follows: When the construction personnel install the steel anchor beam 1, they first place the steel anchor beam 1 on the processing jig, then calibrate the total station in the measurement area of ​​the steel anchor beam 1, and adjust the steel anchor beam 1 to its theoretical posture. Then, four reference points 2 are selected on the top surface of the steel anchor beam 1, and a check point 3 is selected at the bottom of each of the two cableway pipe outlets. The first positioning coordinates of the four reference points 2 are measured using the total station, and the first check coordinates of the two check points 3 are measured. This yields the relative geometric relationships between the four reference points 2 and the anchoring point 4, the four reference points 2 and the center point 5 of the cableway pipe outlet, the two check points 3 and the anchoring point 4, and the two check points 3 and the center point 5 of the cableway pipe outlet. Next, the steel anchor beam 1 is hoisted to the anchoring area, and the second positioning coordinates of the four reference points 2 are measured. Based on the positioning deviation values ​​between the second positioning coordinates and the theoretical coordinates of each reference point 2, the steel anchor beam 1 is adjusted into position. Finally, the position of the steel anchor beam 1 is checked using two check points 3. The position of the steel anchor beam 1 is corrected by combining the four reference points 2 and the two check points 3.
