Fig. 1 is a flow chart illustrating a variable cross-section ultra-high pier vertical degree measurement and control method according to an embodiment of the disclosure.
Referring to fig. 1, in step S101, first coordinates of a plurality of points to be measured on a construction form of an ultra-high pier may be acquired. Here, the ultra-high pier of the present disclosure may be constructed for a pier in a segmental casting form using a construction method of a hydraulic creeping formwork, so that the first coordinates may include at least the second coordinates at the top of the cast pier segment of the ultra-high pier. Further, a measuring net can be established, and then the total station is utilized to measure the first coordinates of the points to be measured. Further, the specific number and position of the plurality of points to be measured on the construction form can be determined by those skilled in the art according to actual needs, and the disclosure is not limited thereto.
Next, in step S102, a first fitting may be performed on the projection line of the construction template on the reference vertical plane based on the first coordinate, so as to obtain a first line function. Here, the reference vertical plane is perpendicular to the plane of the construction form. Further, based on the first coordinates, the first fitting may be performed, but is not limited to, by a least squares method to determine fitting parameters of the first line function.
Next, in step S103, a slope angle of the construction form may be obtained, and a second fitting may be performed on the projection line of the construction form on the reference vertical plane based on the slope angle and the second coordinate, to obtain a second line function. Here, the construction form may be measured for a slope angle using a digital sag gauge.

And may be the slope of the second line function, so that in the case of a certain slope, the second fitting may be performed by, but not limited to, a least squares method in combination with the second coordinate to determine the fitting parameters in the second line function. By combining the slope collection angle measured by the digital sag gauge and the second coordinate fitting second line function measured by the total station, the influence of the single measuring device on the measurement and control result can be reduced, and therefore errors in construction measurement and control are reduced.
Referring back to fig. 1, in step S104, a first horizontal distance between a first point location on the construction template and a preset second point location may be obtained, and a third fitting may be performed on the projection line of the construction template on the reference vertical plane based on the first horizontal distance and the second coordinate, so as to obtain a third line function. Here, the first horizontal distance between the first point location and the preset second point location on the construction form may be measured using a laser plummet.
Fig. 3 is a schematic diagram illustrating a principle of a laser plummet according to an embodiment of the present disclosure, and as shown in fig. 3, a first point position may be used as a target ruler position, and a second point position may be used as a laser plummet position, so that a first horizontal distance between the first point position and the second point position may be measured by using the target ruler and the laser plummet. According to the embodiment of the present disclosure, the first horizontal distance is obtained

And may be the slope of the third line function, so that in the case of a certain slope, the third fitting may be performed by, but not limited to, a least square method in combination with the second coordinate to determine the fitting parameters in the third line function. By combining the first horizontal distance measured by the laser plummet and the second coordinate fitting third linear function measured by the total station, the influence of the single measuring device on the measurement and control result can be reduced, and therefore the error in construction measurement and control is reduced.

In scientific research or high-accuracy measurement, measurement and comparison can be performed by different devices, different measurement methods, different measurement times and different measurers under different measurement conditions, and the measurement is called unequal precision measurement. Since the unreliability of the various measurement results of unequal accuracy measurements is different, the arithmetic mean of the measurement values cannot be simply taken as the final measurement result, but the measurement result with a high degree of reliability should have a higher weight and the measurement result with a low degree of reliability should have a lower weight. In other words, the reliability of the observation values with different accuracies is different, and the influence exerted on the calculation is also different. This requires selecting a quantity for comparing the confidence level between the observations, which is a weight, and the more reliable observations should be weighted more heavily. The purpose of weighting is to weigh the contribution of the unequal precision measurement data to the final result, the weights are relative, the weighting objects are the data of the unequal precision measurements, and the weighting is because the unequal precision measurement data have different precisions, so that the arithmetic mean is not convenient to be used for synthesizing the final result.
Therefore, referring back to fig. 1, in step S105, the first line function, the second line function, and the third line function may be weighted to obtain a composite line function.
According to an embodiment of the present disclosure, the first linear function may be subjected to a preset weighting
Figure 271378DEST_PATH_IMAGE048
Second line function
Figure 454097DEST_PATH_IMAGE049
And a third line function

Performing weighted summation, and taking the result of weighted summation as a synthetic line function

. Further, the preset weight may include a first weight of the first line function
Figure 240154DEST_PATH_IMAGE052
Second weight of the second line function
Figure 859354DEST_PATH_IMAGE053
And a third weight of a third linear function
Figure 159010DEST_PATH_IMAGE054
Thereby to make
Figure 154648DEST_PATH_IMAGE055
In accordance with embodiments of the present disclosure, in one possible implementation, the first weight may be determined based on an accuracy of a first device that measures the first coordinate, the second weight may be determined based on an accuracy of a second device that measures the roll angle, and the third weight may be determined based on an accuracy of a third device that measures the first horizontal distance. Here, before the weighting processing is performed on the first line function, the second line function, and the third line function, a sum of the accuracies of the first device, the second device, and the third device may be calculated; then, the ratio of the accuracy of the first device to the sum is taken as a first weight, the ratio of the accuracy of the second device to the sum is taken as a second weight, and the ratio of the accuracy of the third device to the sum is taken as a third weight. As an example, the first device is a total station, the second device is a digital plummet, and the third device is a laser plummet, such that the first weight

Accuracy that can be based on total powerstation

To determine, in particular, that
Figure 158879DEST_PATH_IMAGE059
Figure 729276DEST_PATH_IMAGE060
And an
Figure 169484DEST_PATH_IMAGE061
. Here, the accuracy of each device can be determined by the content of the specification of each device, and the disclosure is not repeated herein. The weights are distributed according to the equipment accuracy by fitting the linear functions obtained by utilizing different equipment, so that the comprehensive adjustment is carried out, the distribution of the weights is reasonable, the weight distribution is easy to understand and implement, the problem that the weights are not reasonably distributed in the adjustment process of measuring and controlling the verticality of the ultrahigh pier in the related technology is solved, and the measurement and control accuracy of the verticality of the ultrahigh pier is improved.
It should be understood that the above description of determining the weights of the respective line functions by using the accuracy of the respective devices is only an exemplary illustration, and the present disclosure does not limit this, i.e., a person skilled in the art can determine the specific distribution manner of the weights according to actual situations. For example, in another possible implementation, the weights of the respective line functions may be determined from the measured variances of the respective devices using a unit weight variance method.
Next, in step S106, a verticality deviation of the ultra-high pier at the target height may be calculated based on the composite line function, and the construction form may be adjusted based on the verticality deviation.
According to the embodiment of the disclosure, when the vertical degree deviation of the ultrahigh pier at the target height is obtained through calculation based on the comprehensive line function, the third horizontal distance between the third point of the ultrahigh pier at the target height H and the pier bottom of the ultrahigh pier can be determined based on the comprehensive line function
Figure 35809DEST_PATH_IMAGE062
Then, a third horizontal distance is calculated
Figure 295889DEST_PATH_IMAGE062
At a predetermined fourth horizontal distance
Figure 109124DEST_PATH_IMAGE063
And the ratio of the difference to the target height is taken as the vertical deviation T, i.e.
Figure 138260DEST_PATH_IMAGE064
. Here, the fourth horizontal distance is a theoretical horizontal distance between the third point location and the bottom of the ultra-high pier, which is determined based on the construction design. The vertical degree deviation of the ultrahigh pier is determined by combining the actually measured third horizontal distance obtained by utilizing the comprehensive line function and the fourth horizontal distance which is a design value, so that the vertical degree deviation condition of the ultrahigh pier can be accurately reflected, and increasingly severe measurement and control precision requirements of the ultrahigh pier are met.
According to the embodiment of the disclosure, when the construction formwork is adjusted based on the verticality deviation, the inclination state of the construction formwork can be determined based on the verticality deviation, then the absolute value of the difference is used as the formwork adjustment value, and the construction formwork is adjusted based on the formwork adjustment value and the inclination state. Here, in the case where the vertical degree deviation is greater than 0, it may be determined that the inclination state is the first state; in the case where the deviation of the vertical degree is less than 0, it may be determined that the inclination state is the second state; in the case where the vertical degree deviation is equal to 0, the inclination state may be determined to be the third state.
