Continuous measurement method for flatness of concrete terrace

Abstract

According to the concrete terrace flatness continuous measurement method provided by the invention, a wheel type measurement trolley carrying an inertial measurement unit, an odometer and other various sensors traverses on the surface of a to-be-measured terrace according to a planned measurement line, and meanwhile, a total station is used for tracking the wheel type measurement trolley in real time and obtaining position measurement data; and then using coordinates measured by the total station as control points to restrain a measurement result. And then, carrying out inertial navigation / odometer / total station multi-source data fusion calculation to obtain the optimal track of the movement of the measurement trolley. And the elevation grid is obtained through measuring line splicing and indirect adjustment. And finally, the flatness information of the to-be-measured terrace is obtained through a flatness calculation algorithm. Compared with a traditional concrete terrace measuring method, the measuring method provided by the invention has the advantages that the efficiency is high, and the requirement on operators is not harsh; the precision is good, and the measurement precision of a level gauge can be completely achieved; the measuring result is good in repeatability, accidental errors can be reduced to the minimum, and human factors in the measuring result are greatly eliminated.

Description

Technical field [0001] The present invention relates to the field of surveying and mapping, and more particularly to a continuous measurement method of condensation flooring flatness. Background technique [0002] According to the current floor acceptance standard, a floor of a high difference in the 2 meter is not more than ± 4mm can be called super flat. With the continuous advancement of concrete floor construction technology, super flat floor is widely used, more common in all major logistics storage centers, equipment factory, underground parking, indoor stadium and other places. Super flat flooring uses integrated construction methods, not only saves investment costs, but also enhances the wear resistance of the floor and extend its useful life. [0003] During the concrete floor measurement, the common flatness measurement method includes horizontal tape and plug, a level, and a level. The horizontal tip and the plug measurement method is easy to operate, but the measureme...
