Description

Technical Field

[0001] The invention relates to the technical field of power transmission line construction, and in particular to an installation parameter determination method and a construction method for inserting a steel pipe type power transmission tower foundation. Background Art

[0002] The steel pipe insertion foundation of the transmission tower is an excavation-type foundation in which the main material of the tower leg of the transmission tower is directly inserted into the foundation concrete column. This construction structure or form is disclosed in Chinese patent documents such as "CN202099809U" and "CN115059077A".

[0003] Current transmission towers usually have four tower legs, and correspondingly, four corresponding tower foundations are required when assembling the transmission tower. Figure 1 For example, in the case of inserting a steel pipe transmission tower foundation, the general construction steps are as follows: casting a cap structure and a column structure at the center point of the current tower foundation, pre-embedding a positioning anchor bolt group in the column structure, connecting the connecting flange at the lower end of the steel pipe (10) to the positioning anchor bolt group, and then casting a pier column structure around the steel pipe to form the tower foundation.

[0004] Steel pipe inserted foundations are generally used in high-voltage transmission lines, that is, the steel pipes in the steel pipe inserted foundations usually have larger sizes and deadweights. Taking a ±800kV ultra-high voltage DC transmission line as an example, the total length of a single steel pipe in a steel pipe inserted foundation in the line project is 8.7 meters, the total diameter is 1.9 meters, and the total deadweight is 27.5 tons. This means that in the actual construction process, relying solely on the alignment and fixation between the lower end connecting flange of the steel pipe and the embedded positioning anchor bolt group cannot guarantee the displacement of the upper end of the steel pipe due to the deformation of its own weight.

[0005] In current construction, the posture of the upper area of ​​the steel pipe is generally adjusted by tensioning the upper end and / or middle of the steel pipe with ground anchors. However, in practical applications, there is no relatively fast method for obtaining or collecting data based on posture adjustment. Summary of the invention

[0006] In order to solve the problem of low efficiency in obtaining the posture parameters of the steel pipe inserted in the foundation of the steel pipe transmission tower during and after the construction, the present invention provides a method for measuring the installation parameters of the foundation of the steel pipe inserted in the steel pipe transmission tower and a construction method, which establishes a measurement system based on the upper end face of the flange of the connecting flange at the upper end of the steel pipe, and obtains the installation parameters of the steel pipe inserted in the steel pipe transmission tower at the current tower foundation by constructing an observation reference point, which can quickly, conveniently and accurately provide basis data for the posture adjustment of the steel pipe, and can realize the measurement of the final actual construction parameters.

[0052] The present invention has the following beneficial technical effects:

[0053] (1) The four tower legs of the transmission tower are evenly arrayed around the midpoint of the tower, that is, for the same inserted steel pipe transmission tower, its four tower foundations are also evenly arrayed around the midpoint of the tower; during the tower construction, the coordinates of the midpoint of the tower and the coordinates of the center point of each tower foundation are known design values; in the present disclosure, the first reference point is located at the midpoint of the tower, and the second reference point and the third reference point are respectively located at the midpoint of the line connecting the current tower foundation and the two adjacent tower foundations, so the position coordinates of the first reference point, the second reference point and the third reference point can be directly obtained based on the design value of the tower; at the same time, since the four tower foundations of the same transmission tower are cast and constructed in sequence, based on the selection of the observation reference point disclosed in the present disclosure, when the four tower foundations are constructed in sequence, the position of the first reference point does not need to be changed, and when the installation parameters of the tower foundation are measured each time, only one of the observation reference points needs to be adjusted to achieve rapid collection of relevant parameters;

[0054] (2) The present disclosure can quickly and accurately obtain the torsional posture of the steel pipe in the circumferential direction based on the torsional state of the upper end face of the flange. It can be understood that, under ideal conditions, the straight line of the first observation plane and the straight line of the first reference plane, the straight line of the second observation plane and the straight line of the second reference plane, and the straight line of the third observation plane and the straight line of the third reference plane should all be collinear. However, under actual working conditions, the steel pipe will be twisted both overall and locally due to its own weight. In the present disclosure, the torsional posture parameters of the steel pipe are measured from three different angles, and the angle of the projected straight line on the horizontal plane is used as the judgment standard, which can realize the rapid and accurate measurement of relevant parameters;

[0055] (3) The present disclosure can measure the inclination angle of the steel pipe in space based on, for example, only the height coordinates of 8 measurement marks and the known length parameters of the steel pipe. This method has the advantages of both high efficiency and accuracy.

[0056] (4) The present invention can quickly obtain the inclination parameters of the upper end surface of the flange in the horizontal and vertical directions based only on the distance between two points in the height direction and the distance in the horizontal direction. At the same time, through the correction of auxiliary parameters such as the first auxiliary horizontal inclination parameter and the second auxiliary horizontal inclination parameter, as well as the first auxiliary vertical inclination parameter and the second auxiliary vertical inclination parameter, the accuracy of the relevant data can be ensured.

[0058] Figure 2 This is a deployment diagram of the installation parameter determination method in Example 1. DETAILED DESCRIPTION

[0059] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it. Example

[0060] In the present disclosure, in order to ensure that the posture of the steel pipe 10 can be adjusted based on the construction process of inserting the steel pipe type transmission tower foundation, the present disclosure establishes a measurement system based on the flange upper end face 30 of the connecting flange 20 at the upper end of the steel pipe 10, and obtains the installation parameters of the steel pipe 10 inserted into the steel pipe type transmission tower at the current tower foundation by constructing an observation reference point. It can quickly, conveniently and accurately provide basis data for the posture adjustment of the steel pipe 10, and can realize the determination of the final actual construction parameters.

[0061] See Figure 2In a specific embodiment of the present disclosure, a method for determining installation parameters of an inserted steel tube transmission tower foundation is provided, which comprises the following steps:

[0062] A plurality of measuring marks are provided on the flange upper end surface 30 of the connecting flange 20 located at the upper end of the steel pipe 10;

[0063] Establish multiple observation reference points on the ground; and,

[0064] Based on the measurement positions of the multiple measurement marks at the multiple observation reference points, the installation parameters of the steel pipe 10 inserted into the steel pipe type transmission tower at the current tower foundation are obtained.

[0065] The multiple measurement marks include a first point mark 1 located at the lowest point of the flange upper end surface 30, a second point mark 2 located at the flange upper end surface 30 and centrally symmetrical with the first point mark 1 relative to the center point of the flange upper end surface 30 (the second point mark 2 is located at the highest point of the flange upper end surface 30), a third point mark 3 and a fourth point mark 4 centrally symmetrically arranged at the same height of the flange upper end surface 30 with the center point of the flange upper end surface 30, a fifth point mark 5 deflected 45° relative to the first point mark 1 in the circumferential direction of the flange upper end surface 30 in the front side of the route advancement direction, a sixth point mark 6 located at the flange upper end surface 30 and centrally symmetrical with the fifth point mark 5 relative to the center point of the flange upper end surface 30, a seventh point mark 7 deflected 45° relative to the first point mark 1 in the circumferential direction of the flange upper end surface 30 in the rear side of the route advancement direction, and an eighth point mark 8 located at the flange upper end surface 30 and centrally symmetrical with the seventh point mark 7 relative to the center point of the flange upper end surface 30.

[0066] The multiple observation reference points include a first reference point 100 located at the midpoint of the pole tower, a second reference point 200 located at the center point of a line connecting a current pole tower foundation and a pole tower foundation adjacent to a vertical line advancing direction, and a third reference point 300 located at the center point of a line connecting a current pole tower foundation and a pole tower foundation adjacent to a parallel line advancing direction.

[0067] Among them, the installation parameters include the angular torsion parameters of the steel pipe 10 in the circumferential direction at the current tower foundation, the inclination parameters of the steel pipe 10 in the vertical direction at the current tower foundation, the inclination parameters of the flange upper end face 30 of the steel pipe 10 at the current tower foundation in the horizontal direction, and the inclination parameters of the flange upper end face 30 of the steel pipe 10 at the current tower foundation in the vertical direction.

[0068] In this embodiment, the direction of the line connecting the first reference point 100 and the center point of the current tower foundation can be used as the horizontal direction, and the direction perpendicular to the horizontal direction can be used as the vertical direction.

[0069] The four tower legs of the transmission tower are evenly arrayed around the midpoint of the tower, that is, for the same inserted steel pipe transmission tower, its four tower foundations are also evenly arrayed around the midpoint of the tower; during the tower construction, the coordinates of the midpoint of the tower and the coordinates of the center point of each tower foundation are all known design values; in the present disclosure, the first reference point 100 is located at the midpoint of the tower, and the second reference point 200 and the third reference point 300 are respectively located at the midpoint of the line connecting the current tower foundation and the two adjacent tower foundations, so the position coordinates of the first reference point 100, the second reference point 200 and the third reference point 300 can be directly obtained based on the design value of the tower; at the same time, since the four tower foundations of the same transmission tower are cast and constructed in sequence, based on the selection of the observation reference point of the present disclosure, when the four tower foundations are constructed in sequence, the position of the first reference point 100 does not need to be changed, and when the installation parameters of the tower foundation are measured each time, only one of the observation reference points needs to be adjusted to achieve rapid collection of relevant parameters.

[0070] In this embodiment, the offset values ​​of the eight measurement marks at the flange upper end surface 30 are all 45°, and in order to facilitate subsequent data processing, the distance between any measurement mark and the center point of the connecting flange end surface can be equal.

[0071] In addition, in this embodiment, a spatial observation coordinate system can be established with the first reference point 100 as the origin, and the measurement positions of the multiple measurement marks at the multiple observation reference points can include the spatial coordinates of the multiple measurement marks in the spatial observation coordinate system. Therefore, it can be better to obtain relevant data and improve the efficiency of measuring installation parameters.

[0072] The selection of the measurement marks in the present disclosure enables the presence of a first point mark 1 corresponding to the first reference point 100, a fifth point mark 5 corresponding to the second reference point 200, and a seventh point mark 7 corresponding to the third reference point 300. That is, based on parameters such as the measurement position of the first point mark 1 at the first reference point 100, the measurement position of the fifth point mark 5 at the second reference point 200, and the measurement position of the seventh point mark 7 at the third reference point 300, multiple installation parameters can be acquired efficiently and quickly.

[0073] In this embodiment, the acquisition of the angular torsion parameters of the steel pipe 10 at the current tower base in the circumferential direction can include, for example,

[0074] Obtain a first angular offset parameter of the first point mark 1 offset from a line connecting the first reference point 100 and the center point of the flange upper end surface 30;

[0075] Obtain a second angular offset parameter of the fifth point mark 5 offset from a line connecting the second reference point 200 and the center point of the flange upper end surface 30;

[0076] Obtain a third angular offset parameter of the seventh point mark 7 offset from a line connecting the third reference point 300 and the center point of the flange upper end surface 30;

[0077] Based on the first angular offset parameter, the second angular offset parameter and the third angular offset parameter, the angular torsion parameter of the steel pipe 10 in the circumferential direction at the current tower foundation is obtained.

[0078] In the above, the acquisition of the first angular offset parameter may include, for example:

[0079] Obtaining a first observation plane straight line based on the plane coordinates of the first reference point 100 and the center point of the flange upper end surface 30;

[0080] Acquire a first reference plane straight line based on the plane coordinates of the first point mark 1 and the second point mark 2;

[0081] The included angle between the first observation plane straight line and the first reference plane straight line is taken as the first angular offset parameter.

[0082] In the above, the acquisition of the second angular offset parameter can include, for example,

[0083] Obtaining a second observation plane straight line based on the plane coordinates of the second reference point 200 and the center point of the flange upper end surface 30;

[0084] Acquire a second reference plane straight line based on the plane coordinates of the fifth point mark 5 and the sixth point mark 6;

[0085] The included angle between the second observation plane straight line and the second reference plane straight line is taken as the second angular offset parameter.

[0086] In the above, the acquisition of the third angular offset parameter can include, for example,

[0087] Obtaining a third observation plane straight line based on the plane coordinates of the third reference point 300 and the center point of the flange upper end surface 30;

[0088] Acquire a third reference plane straight line based on the plane coordinates of the seventh point mark 7 and the eighth point mark 8;

[0089] The angle between the third observation plane straight line and the third reference plane straight line is taken as the third angle offset parameter.

[0090] Based on the above, the torsional state of the upper end face 30 of the flange can be used to quickly and accurately obtain the torsional posture of the steel pipe 10 in the circumferential direction. It can be understood that, under ideal conditions, the straight line of the first observation plane and the straight line of the first reference plane, the straight line of the second observation plane and the straight line of the second reference plane, and the straight line of the third observation plane and the straight line of the third reference plane should all be collinear. However, under actual working conditions, the steel pipe 10 will be twisted both overall and locally due to its own weight. In the present disclosure, the torsional posture parameters of the steel pipe 10 are measured from three different angles, and the angle of the projected straight line on the horizontal plane is used as a criterion for judgment, so that the relevant parameters can be measured quickly and accurately.

[0091] It can be understood that the straight line equations in the present disclosure, such as the first observation plane straight line, the first reference plane straight line, the second observation plane straight line, the second reference plane straight line, the third observation plane straight line and the third reference plane straight line, can all be constructed using the two-point form, and the straight line angles can also be directly obtained based on the coefficients or constant terms of the straight line equations, which will not be elaborated in this embodiment.

[0092] Meanwhile, the acquisition of the angular torsion parameter includes taking the average of the first angular offset parameter, the second angular offset parameter and the third angular offset parameter as the angular torsion parameter. Therefore, the average can be preferably used as the actual construction parameter to achieve an intuitive evaluation of the torsion posture of the steel pipe 10.

[0093] In this embodiment, the acquisition of the vertical tilt parameters of the steel pipe 10 at the current tower foundation may include, for example:

[0094] Get the height coordinates of the center point of the current tower foundation;

[0095] Obtain the height coordinate of the center point of the upper end surface 30 of the flange;

[0096] Based on the height coordinate of the center point of the current tower foundation, the height coordinate of the center point of the flange upper end surface 30 and the length of the steel pipe 10 , the inclination parameter of the steel pipe 10 at the current tower foundation in the vertical direction is obtained.

[0097] The height coordinate of the center point of the flange upper end surface 30 can be obtained based on, for example, the average value of the height coordinates of the plurality of measurement marks.

[0098] Based on the above, the present disclosure can measure the inclination angle of the steel pipe 10 in space based only on the height coordinates of, for example, 8 measurement marks and the known length parameters of the steel pipe 10. This method has the advantages of both high efficiency and precision.

[0099] It is understandable that the height coordinate of the center point of the current tower foundation actually corresponds to the coordinate of the center point of the lower end of the steel pipe 10. The height coordinate of the center point of the current tower foundation can be directly obtained as a design value or a known value during the construction process.

[0100] In this embodiment, the acquisition of the horizontal inclination parameter of the flange upper end surface 30 of the steel pipe 10 at the current tower foundation can include, for example,

[0101] Based on the plane coordinates of the first point marker 1 and the second point marker 2, obtaining the distance parameter between the first point marker 1 and the second point marker 2;

[0102] Based on the height coordinates of the first point marker 1 and the second point marker 2, obtaining a height difference parameter between the first point marker 1 and the second point marker 2;

[0103] Based on the distance parameter and the height difference parameter between the first point mark 1 and the second point mark 2, the inclination parameter of the flange upper end surface 30 of the steel pipe 10 at the current tower foundation in the horizontal direction is obtained.

[0104] Furthermore, it is also possible to obtain the first auxiliary horizontal inclination parameters based on the fifth point mark 5 and the eighth point mark 8, obtain the second auxiliary horizontal inclination parameters based on the seventh point mark 7 and the sixth point mark 6, and correct the horizontal inclination parameters of the flange upper end face 30 of the steel pipe 10 at the current tower foundation based on the first auxiliary horizontal inclination parameters and the second auxiliary horizontal inclination parameters.

[0105] Based on the above, the horizontal inclination parameters of the upper end face 30 of the flange can be quickly acquired based only on the distance between the two points in the height direction and the distance in the horizontal direction. At the same time, the accuracy of the relevant data can be ensured by correcting the first auxiliary horizontal inclination parameters and the second auxiliary horizontal inclination parameters.

[0106] It can be understood that the first auxiliary horizontal tilt parameter and the second auxiliary horizontal tilt parameter are obtained by referring to the related horizontal tilt parameters obtained based on the first point mark 1 and the second point mark 2, which will not be elaborated here.

[0107] In this embodiment, when the first auxiliary horizontal tilt parameter and the second auxiliary horizontal tilt parameter participate in data correction, the first auxiliary horizontal tilt parameter, the second auxiliary horizontal tilt parameter and the average of the relevant horizontal tilt parameters obtained based on the first point mark 1 and the second point mark 2 can be used as the final measured horizontal tilt parameter of the flange upper end face 30.

[0108] In this embodiment, the acquisition of the vertical inclination parameters of the flange upper end surface 30 of the steel pipe 10 at the current tower foundation can include, for example,

[0109] Based on the plane coordinates of the third point mark 3 and the fourth point mark 4, obtaining the distance parameter between the first point mark 1 and the second point mark 2;

[0110] Based on the height coordinates of the third point mark 3 and the fourth point mark 4, the height difference parameter between the first point mark 1 and the second point mark 2 is obtained;

[0111] Based on the distance parameter and the height difference parameter of the third point mark 3 and the fourth point mark 4, the inclination parameter of the flange upper end surface 30 of the steel pipe 10 at the current tower foundation in the vertical direction is obtained.

[0112] Furthermore, it is also possible to obtain the first auxiliary vertical inclination parameters based on the fifth point mark 5 and the seventh point mark 7, obtain the second auxiliary vertical inclination parameters based on the eighth point mark 8 and the sixth point mark 6, and correct the vertical inclination parameters of the flange upper end face 30 of the steel pipe 10 at the current tower foundation based on the first auxiliary vertical inclination parameters and the second auxiliary vertical inclination parameters.

[0113] Based on the above, the vertical inclination parameters of the upper end face 30 of the flange can be quickly acquired based only on the distance between the two points in the height direction and the distance in the horizontal direction. At the same time, the accuracy of the relevant data can be ensured by correcting the first auxiliary vertical inclination parameters and the second auxiliary vertical inclination parameters.

[0114] As an illustration, for example, the first auxiliary horizontal tilt parameter, the first auxiliary vertical tilt parameter and other tilt parameters can obtain the tangent value of the inclination angle based on the height difference parameter of the corresponding two measurement marks and the distance parameter on the horizontal plane, and the corresponding inclination angle value can be obtained by calculating the inverse function of the trigonometric function, and the inclination angle value can be used as the corresponding inclination parameter; it will not be repeated in this embodiment. Example

[0115] Based on the installation parameter determination method provided in Example 1, another embodiment of the present disclosure further provides a construction method for inserting a steel tube type transmission tower foundation, which can obtain the installation parameters of the steel pipe 10 inserted into the steel tube type transmission tower at the current tower foundation based on the installation parameter determination method in Example 1, and adjust the installation position of the steel pipe 10 at the current tower foundation in real time based on the obtained installation parameters.

[0116] In fact, the method provided in Example 1 can be applied simultaneously to the measurement of actual construction parameters of the inserted steel tube transmission tower foundation after the construction is completed and the parameter control during the construction process as described in this example.
