Embodiment Construction
[0015] The present invention will be described in further detail below through specific examples. The following examples are only descriptive and not restrictive, and cannot limit the protection scope of the present invention.
[0016] A method for measuring the elevation of the top of an ultra-high column, and its pouring inversion method includes the following steps:
[0017] ⑴. Measure an elevation point h of 0.5m or 1m on the side wall of the ultra-high column;
[0018] ⑵. The total station is set up at point A which is 1.5 times the height of the super-high column along the axis direction on the side of the super-high column with the elevation point h;
[0019] ⑶. Measure the distance of S1 along the direction of the total station at the bottom of the ultra-high column to determine point B, control S1 at 0.2m-0.5m, set up a prism at point B, and measure the horizontal distance from the total station to the prism with the total station S;
[0020] ⑷. Observe the elevation point h w...

The invention relates to a method for measuring the elevation of the top of an ultrahigh column. The method comprises the following steps: (1), measuring an elevation point h on the side wall of the ultrahigh column; (2), building a total station on a point A at a distance from one side of the ultrahigh column, which is provided with the elevation point h, wherein the distance is controlled to be 1.5 times the height of the ultrahigh column; (3), measuring an S1 distance at the bottom of the ultrahigh column along the direction of the total station and determining a point B, controlling the S1 to be 0.2m-0.5m, arranging a prism at the point B, and measuring the horizontal distance S; (4), observing the elevation point h by using the total station, recording a vertical angle alpha1, and recoding a vertical angle alpha2; and (5), measuring the elevation of the top of the ultrahigh column, wherein the elevation H of the top of the ultrahigh column is equal to h+tanalpha2*(S1+S)+ / -tanalpha1*(S1+S). According to the method, the working time is shortened, and the work risk is lowered. Meanwhile, the measurement precision is ensured, and the safety environment of work is also improved when manpower and material resources are saved for the project from the perspective of conservation.
Description
Technical field [0001] The invention belongs to the field of measurement methods, in particular to a method for measuring the elevation of the top of an ultra-high column. Background technique [0002] At present, public buildings tend to have large spaces and multiple styles. Nowadays, large super-high pillars are very common and play a major supporting role in buildings. Whether the top elevation of the pillars meets the design requirements is particularly important. How to accurately measure the elevation of the top of an ultra-high column above 10 meters in height is a relatively difficult task. In the past, the method of measuring the top elevation of an ultra-high column was mainly determined by measuring the bottom elevation of the column and adding the actual length of the column, or directly measuring from the top of the column with a steel ruler to the bottom elevation of the column to determine the column. Top elevation. These two measurement methods cannot accurate...
