Description

Technical Field

[0001] The present application relates to the field of construction measurement, and in particular to a method for measuring and positioning a high tower column. Background Art

[0002] Among the existing methods for measuring and positioning the templates of high tower columns, most are based on the three-dimensional coordinate method of the total station for direct measurement and positioning. When the total station is used in conjunction with a prism for measuring the construction of high tower columns, the corners of the template are often blocked by the internal steel bars, so that the total station and the measuring prism cannot see through each other, and the measurement work cannot be completed. The template can only be adjusted by measuring the internal points of the template and pulling the tape measure. This cannot guarantee the accuracy of measurement and positioning, affecting the construction progress. Therefore, although the three-dimensional coordinate method of the total station can meet the daily measurement work in an environment with good sight, when the characteristic points of the high tower columns are blocked, the traditional three-dimensional coordinate measurement and positioning technology of the total station cannot complete the template measurement and positioning work.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The embodiment of the present application provides a high tower column measurement and positioning method, which can solve the problem in the related art that when the characteristic points of the high tower column are blocked, the traditional total station three-dimensional coordinate measurement and positioning technology cannot complete the template measurement and positioning operation.

[0036] Among the existing methods for measuring and positioning the templates of high tower columns, most are based on the three-dimensional coordinate method of the total station for direct measurement and positioning. When the total station is used in conjunction with a prism for measuring the construction of high tower columns, the corners of the template are often blocked by the internal steel bars, so that the total station and the measuring prism cannot see through each other, and the measurement work cannot be completed. The template can only be adjusted by measuring the internal points of the template and pulling the tape measure. This cannot guarantee the accuracy of measurement and positioning, affecting the construction progress. Therefore, although the three-dimensional coordinate method of the total station can meet the daily measurement work in an environment with good sight, when the characteristic points of the high tower columns are blocked, the traditional three-dimensional coordinate measurement and positioning technology of the total station cannot complete the template measurement and positioning work.

[0037] It can be seen that the current three-dimensional coordinate method has problems such as slow measurement progress and low accuracy in the actual measurement of high tower column template adjustment. When the characteristic points of high tower columns are blocked, the traditional total station three-dimensional coordinate measurement and positioning technology cannot complete the template measurement and positioning operation. Figure 1 to Figure 2 , the embodiment of the present application provides a high tower column measurement and positioning method, which includes:

[0038] 101: Obtain design coordinates of tower column feature points based on tower column design drawings;

[0039] 102: Use the total station 1 to collect the three-dimensional coordinates of the control point 3 on the high tower column foundation, and mark the three-dimensional coordinates as the collection coordinates of the total station 1;

[0040] 103: Use the GPS measuring device 2 to collect the three-dimensional coordinates of the control point 3 on the high tower column cap, and mark the three-dimensional coordinates as GPS collection coordinates;

[0041] 104: based on the coordinates collected by the total station 1 and the coordinates collected by the GPS, obtaining the difference of the three-dimensional coordinates of the control point 3;

[0042] 105: Obtaining corrected coordinates of the tower column feature point based on the difference between the design coordinates of the tower column feature point and the three-dimensional coordinates of the control point 3;

[0043] 106: Obtaining a deviation value of the tower column feature point based on the measured coordinates of the tower column feature point and the corrected coordinates of the tower column feature point;

[0044] 107: Compare the tower column feature point deviation value with the set threshold range. If the tower column feature point deviation value is within the set threshold range, the high tower column template measurement and positioning is completed. If the tower column feature point deviation value exceeds the set threshold range, adjust the high tower column template position until the tower column feature point deviation value is within the set threshold range.

[0045] In the present application, firstly, the design coordinates of the tower column feature points are obtained based on the tower column design drawings, and then the total station 1 is used to collect the three-dimensional coordinates of the control point 3 on the high tower column foundation, and the three-dimensional coordinates are marked as the total station 1 collection coordinates, and the GPS measuring device 2 is used to collect the three-dimensional coordinates of the control point 3 on the high tower column foundation, and the three-dimensional coordinates are marked as the GPS collection coordinates, and then based on the total station 1 collection coordinates and the GPS collection coordinates, the difference of the three-dimensional coordinates of the control point 3 is obtained, based on the difference between the design coordinates of the tower column feature points and the three-dimensional coordinates of the control point 3, the tower column feature point correction coordinates are obtained, based on the measured coordinates of the tower column feature points and the tower column feature point correction coordinates, the tower column feature point deviation value is obtained, and finally the tower column feature point deviation value is compared with the set threshold range, if the tower column feature point deviation value is within the set threshold range, the high tower column template measurement and positioning is completed, if the tower column feature point deviation value exceeds the set threshold range, the high tower column template position is adjusted until the tower column feature point deviation value is within the set threshold range. The total station 1 is coordinated with the GPS measuring device 2, and the three-dimensional coordinates of the control point 3 obtained by utilizing the characteristic of the GPS measuring device 2 that is not afraid of obstruction are differentially processed with the three-dimensional coordinates of the control point 3 obtained by utilizing the characteristic of the total station 1 with high precision. The difference obtained can be used to correct the design coordinates of the tower characteristic points, guide the adjustment of the high tower template during on-site construction, solve the problem of line of sight obstruction during measurement by the total station 1, directly improve the efficiency of template measurement and positioning, and is simple to operate, which is conducive to accelerating the progress of the project.

[0046] On the basis of the above-mentioned embodiment, in this embodiment, in step 101: obtaining the design coordinates of the tower column feature points based on the tower column design drawings, the specific steps include: based on the plane dimensions of the tower column in the tower column design drawings, calculating the corner point coordinates of the tower column plane polygon corner points in the design line, and the corner point coordinates are the design coordinates of the tower column feature points.

[0047] Specifically, before the project starts, the design unit will send the designed construction drawings to the construction unit. The construction unit will calculate the coordinates of the corner points on the design route (road line direction) based on the plane dimensions of the tower column (here refers to length, width, and height) in the tower column design drawings.

[0048] Generally, the horizontal projection of the tower column plane is mainly presented as a polygon, so there are also multiple corner point coordinates. When measuring and positioning, one or more corner point coordinates can be selected as the tower column feature point design coordinates. For example, in this embodiment, a corner point coordinate is selected as the tower column feature point design coordinate, and the tower column feature point design coordinate is marked as (X, Y, Z).

[0049] On the basis of the above embodiment, in this embodiment, before using the total station 1 to collect the three-dimensional coordinates of the control point 3 on the high tower column base, the method further includes: marking a control point 3 on the high tower column base.

[0050] Specifically, in this embodiment, it should be noted that the control point 3 mark is in line of sight with the designed intersection control point 3. Here, marking the control point 3 means: determining a control point 3 on the high tower column cap, in this embodiment, it is named JM1, and then making a mark at the control point 3 to facilitate finding this control point 3 in subsequent work. When making the mark, a hole is drilled on the high tower column cap and a stainless steel measurement point mark is buried. The control point 3 is needed to determine the acquisition coordinates of the total station 1 and the GPS acquisition coordinates in the future.

[0051] On the basis of the above embodiments, in this embodiment, in step 102: use the total station 1 to collect the three-dimensional coordinates of the control point 3 on the high tower column foundation, and the specific steps include: use the total station 1 in conjunction with the observation prism to measure, and use any two mutually visible designed intersection control points 3 in the high tower column construction area to obtain the three-dimensional coordinates of the control point 3 on the high tower column foundation.

[0052] It should be noted that the design intersection control point 3 is the intersection control point 3 given in the design drawing. There are multiple design intersection control points 3. In this embodiment, any two design intersection control points 3 are selected. It should be noted that it is necessary to ensure that the two design intersection control points 3 can see each other. The two design intersection control points 3 are respectively recorded as G1 and G2. When collecting the three-dimensional coordinates of the control point 3 on the high tower column cap, a total station 1 is set at one of the design intersection control points 3, and an observation prism is set at the other design intersection control point 3. The three-dimensional coordinates of the control point 3 on the high tower column cap are collected by the total station 1 and the observation prism. In order to distinguish the three-dimensional coordinates of the control point 3 on the high tower column cap collected by the subsequent GPS measurement device 2, the three-dimensional coordinates of the control point 3 on the high tower column cap collected by the total station 1 and the observation prism are marked as the total station 1 collection coordinates (X1, Y1, Z1).

[0053] On the basis of the above embodiment, in this embodiment, in step 103: the three-dimensional coordinates of the control point 3 on the high tower column cap are collected using the GPS measurement device 2, and the three-dimensional coordinates are marked as the GPS collection coordinates:

[0054] Specifically, the built-in measurement program of the GPS measurement device 2 of the established engineering project is used to smoothly measure the three-dimensional coordinates (X2, Y2, Z2) of the JM1 point, which are recorded as the GPS acquisition coordinates (X2, Y2, Z2).

[0055] When using the total station 1 to collect the three-dimensional coordinates of the control point 3 on the high tower column foundation and using the GPS measuring device 2 to collect the three-dimensional coordinates of the control point 3 on the high tower column foundation, the three-dimensional coordinates of the control point 3 on the high tower column foundation can be collected by the total station 1 first and then collected by the GPS measuring device 2, or the three-dimensional coordinates of the control point 3 on the high tower column foundation can be collected by the GPS measuring device 2 first and then collected by the total station 1. In this application, no limitation is made.

[0056] On the basis of the above embodiments, in this embodiment, in step 104: based on the coordinates collected by the total station 1 and the coordinates collected by the GPS, the difference in the three-dimensional coordinates of the control point 3 is obtained. The specific steps include: subtracting the coordinates collected by the total station 1 and the coordinates collected by the GPS to obtain the difference in the three-dimensional coordinates of the control point 3.

[0057] Use a calculator to calculate the difference (△X, △Y, △Z) of the three-dimensional coordinates of the JM1 point measured by the total station 1 and the GPS measuring device 2. The coordinates collected by the total station 1 are (X1, Y1, Z1), the coordinates collected by the GPS are (X2, Y2, Z2), and the difference of the three-dimensional coordinates of the control point 3 is (△X, △Y, △Z), △X = X1-X2; △Y = Y1-Y2; △Z = Z1-Z2.

[0058] On the basis of the above embodiments, in this embodiment, in step 105: based on the difference between the design coordinates of the tower column feature point and the three-dimensional coordinates of the control point 3, the corrected coordinates of the tower column feature point are obtained, and the specific steps include: adding the difference between the design coordinates of the tower column feature point and the three-dimensional coordinates of the control point 3 to obtain the corrected coordinates of the tower column feature point.

[0059] In this embodiment, the design coordinates of the tower column feature point obtained in step 101 are added to the three-dimensional coordinate difference (△X, △Y, △Z) in step 104 to obtain the corrected coordinates of the tower column feature point: the design coordinates of the tower column feature point are (X special, Y special, Z special), and the corrected coordinates of the tower column feature point are (X special + △X, Y special + △Y, Z special + △Z).

[0060] On the basis of the above embodiment, in this embodiment, in step 106: obtaining the deviation value of the tower column feature point based on the measured coordinates of the tower column feature point and the corrected coordinates of the tower column feature point, specifically:

[0061] The corrected coordinates of the tower column feature points are input into the notebook of the GPS measuring device 2, and the corrected coordinates of the tower column feature points are laid out using the GPS measuring device 2. Then, the measured coordinates of the tower column feature points are compared with the corrected coordinates of the tower column feature points to calculate the deviation value of the tower column feature points.

[0062] Then proceed to step 107: compare the tower column feature point deviation value with the set threshold range. If the tower column feature point deviation value is within the set threshold range, the high tower column template measurement and positioning is completed. If the tower column feature point deviation value exceeds the set threshold range, adjust the high tower column template position until the tower column feature point deviation value is within the set threshold range.

[0063] When adjusting the position of the high tower column template, use the GPS measuring device 2 to stake out the corrected coordinates of the tower column feature points. Specifically: when the tower column feature point deviation value is within the set threshold range, it means that the tower column feature point deviation value meets the design and specification requirements; if the tower column feature point deviation value exceeds the set threshold range, it means that the tower column feature point deviation value does not meet the design and specification requirements. At this time, the tower column template position is continuously adjusted according to the tower column feature point deviation value (using construction machinery for adjustment) until the tower column feature point deviation value meets the design and specification requirements.

[0064] In summary, a new control point 3 is marked on the high tower column foundation and named JM1. The advantage is that the total station 1 and the GPS measuring device 2 can measure the same control point 3 each time, thereby improving the accuracy of construction layout.

[0065] The advantages of the high precision of the total station 1 and the fact that the GPS measuring device 2 does not require line of sight are fully utilized, and the efficiency of the measuring operation and the progress of the construction are improved on the basis of ensuring the measuring accuracy.

[0066] The coordinates of the JM1 control point 3 on the high tower column foundation are measured respectively by using the total station 1 and the GPS measuring device 2, which is simple to operate and can be achieved quickly.

[0067] The difference in the three-dimensional coordinates of the point JM1 measured by the total station 1 and the GPS measuring device 2 is calculated using a calculator (△X, △Y, △Z). The result can be obtained immediately on site without the need to collect data in the field and then process it indoors, thus shortening the measurement operation time.

[0068] The three-dimensional coordinate difference (△X, △Y, △Z) obtained by the calculator on site is used to correct the design coordinates of the tower column feature points, and the GPS measuring device 2 is used to lay out the corrected coordinates. This operation method is real-time, fast and accurate. Among them, the measurement work of measuring the plane position and elevation of the engineering building on the design drawing to the actual site using certain measuring instruments and methods is called construction layout (also called construction layout).

[0069] Therefore, the present application uses the GPS measuring device 2 to measure and locate the template whose line of sight is blocked by the high tower column, and uses the total station 1 to assist in the measurement and perform differential processing on the data collected by the GPS measuring device 2. The differential value obtained is used to correct the high tower column template data, and guide the adjustment of the high tower column template during on-site construction. This solves the problem of line of sight blocked during measurement by the total station 1, directly improves the efficiency of template measurement and positioning, is simple to operate, and is conducive to accelerating the progress of the project.
