Problems solved by technology
There are multiple errors accumulated in this process. First, there are human errors in the process of snapping the line, and the line width error cannot be ignored; second, there are human reading errors in the process of the construction personnel checking the wall to the 200 control line, and These errors continue to accumulate with the increase of the wall, which greatly affects the accuracy of the PC wall setting-out; third, due to the complexity of the construction site, construction tools are piled up in many places, and the setting-out measurement cannot be carried out

Embodiment 1
[0027] Such as figure 1 As shown, it is known from the design drawings that the height of the first wall 1 and the second wall 2 is 3m, the total station is 5m away from the first wall 1 along the Y direction, and 6m away from the second wall 2 along the X direction. The conversion height of instrument 3 is 1.2m.
[0028] Draw the upper line and the lower line on the same horizontal line as the measured surface of the first wall 1 and the measured surface of the second wall 2, where the distance between the lower line and the bottom of the wall is 0.3m, and the distance between the lower line and the upper line is 1m. The second wall 2 is respectively used as the vertical line of the upper line and the lower line (two for each surface, a total of four), so as to obtain a total of eight measuring points 4:

A method for quickly measuring and calibrating a PC wall based on a total station measures and calibrates the horizontal position deviation and verticality of the PC wall when the PC wall is hoisted on a prefabricated building construction site. Reserve the total station control point on the construction site to set up the total station, use chalk to mark two straight lines at a fixed distance L on the wall of the PC under test, and use the total station to measure the total station to the mark on the PC wall The vertical distance of any point on two straight lines can be used to obtain several X 上 and x 下 , similarly, when there is a deviation in the verticality of the PC wall, the corresponding points on different straight lines must show the same deviation trend, which can easily, efficiently and accurately calculate the deviation angle and direction of the wall. The invention can be applied to more complex on-site measurement environments, and can greatly save manpower. It can check the horizontal deviation and verticality deviation of PC wall installation in real time and correct them immediately, and promotes the efficiency of PC wall installation and construction calibration in prefabricated buildings. improve.
Description
technical field [0001] The invention belongs to the field of construction engineering measurement, in particular to a PC wall rapid measurement and calibration method based on a total station. Background technique [0002] With the transformation and upgrading of my country's economic and social development, especially the acceleration of the urbanization strategy, the national policy has raised the development of prefabricated buildings to a new height, and prefabricated buildings have gained unprecedented development opportunities. However, various factors under the current situation make the development of prefabricated houses face difficulties. The procedures in the planning and design stage, production stage, construction installation and acceptance stage are out of line, making it difficult to guarantee the quality of prefabricated houses. However, the industrialization and patterning of assembly type construction requires high-precision measurement to ensure, otherwis...
