Total station collimation line method horizontal displacement observation platform and application method thereof

Abstract

The invention relates to a total station collimation line method horizontal displacement observation platform. The total station collimation line method horizontal displacement observation platform comprises a foundation support, a slideway which is arranged on the foundation support, a collimation part which is perpendicular to the foundation support and can slide along the slideway, a pointer which is fixed on the bottom of the collimation part, a scale surface which is arranged on the foundation support and corresponds to a reading pointer and a laser. When the observation platform is in use, the scale surface of the total station collimation line method horizontal displacement observation platform is closely fit to a moved deformation monitoring point, an observation direction is determined by virtue of laser transmitted by the laser, the scale surface is adjusted to be perpendicular to a collimation plane, three adjusting screws are rotated to guarantee the levelness of the foundation support, an initial scale value, which is aligned at the center of the deformation monitoring point, of the observation platform at the moment is recorded, a deformation monitoring point is found, the collimation part is horizontally moved by an operator of the observation platform, a reflecting plate with a collimation crossing on the collimation part is overlapped with a cross wire in a total station telescope, the scale value corresponding to the reading pointer is recorded, and the initial scale value is subtracted from the scale value to obtain the displacement of the deformation point deviated from the collimation plane, namely the displacement of the deformation point relative to an original position. The total station collimation line method horizontal displacement observation platform is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to an observation platform for measuring horizontal displacement by a total station line-of-sight method and a use method thereof, belonging to the field of engineering measurement, and is an auxiliary positioning and measuring platform for measuring horizontal displacement by a total station line-of-sight method. Background technique [0002] The line-of-sight method is one of the methods for structural displacement measurement of general engineering projects, and is commonly used in engineering monitoring. Its measurement principle is: select two stable datum points, set the total station on one of the datum points, adjust the total station, aim at the other datum point, use the vertical line of sight of the total station as the datum, and then Arrange deformation monitoring points on the intersection of the collimation plane and the structural surface to be monitored. As the construction progresses, resulting in structural def...

Problems solved by technology

[0005] 2. When the ruler is placed, it cannot be read horizontally, that is, the reading error caused by the ruler surface not being perpendicular to the line of sight is relatively large;

[0006] 3. The diameter of the measuring drill is too large. In order to determine the center line of the measuring drill, it will cause reading errors when estimating and reading, and this error is relatively large;

[0007] 4. When reading, the inclination of the line of sight caused by the inclination angle between the surveyor's eyes and the measuring drill ruler causes reading errors, which are relatively large;

[0008] 5. Aiming error when the total station is aiming at the braze measurement

[0009] Due to the above-mentioned errors, the measurement accuracy of the reading method of measuring drill and ruler is not high. At present, it can only be estimated to 1mm, and in the process of reading, the surveyor needs to determine the station position according to the direction of the line of sight, and needs to Repeatedly adjusting the position and verticality of the measuring brazing, this method consumes more time, requires higher physical fitness of the surveyors, and lower work efficiency
