RTK system-based building construction verticality measurement method

Abstract

The invention discloses a RTK system-based building construction verticality measurement method. A rectifier is included. Through satellite positioning, multi-satellite continuous correction and RTK dynamic coordinate data grabbing of the rectifier, check point horizontal latitude / longitude coordinate + / - 0.5 cm and elevation coordinate + / - 1 cm data is realized, and the data is displayed on a display screen of the rectifier while grabbing. The rectifier will guide the data into a background control center through a communication module, and the data center corrects the centre-of-gravity shift problem and construction height data statistics in the high-rise construction through software differential data analysis. By the method, defects of existing measurement methods are effectively overcome. By fixedly installation on a certain fixed vertical coordinate point of a slip form, real-time high-precision measurement during each-layer building process can be realized, and a series of problems due to measurement after construction are effectively overcome. In addition, no traditional laser or theodolite is required for correction, 24-hour effective operation without the influence of bad environment can be realized, and anti-interference capability is strong.

Description

technical field [0001] The invention relates to the field of construction industry, in particular to a method for verticality measurement and elevation monitoring of high-rise buildings (or structures) and large-scale facility construction. Background technique [0002] As we all know, the verticality measurement of general high-rise buildings can only be measured after the construction is completed or part of the construction is completed. How to keep the real-time verticality of the construction of high-rise buildings? In the actual high-rise building construction process, there are many instruments for measuring verticality, but these instruments have various shortcomings, which lead to the existence of verticality errors, and cannot solve the verticality problem well. [0003] For example, the following measurement methods have inevitable shortcomings in their measurement process: [0004] 1. When using a hammer ball to measure the verticality of a high-rise building, b...

AI Technical Summary

Problems solved by technology

[0004] 1. When using a hammer ball to measure the verticality of a high-rise building, because the floor of the high-rise building is too high, the hammer ball will swing back and forth due to external interference during the high-altitude measurement process, so that the hammer ball will produce a large error in the shaking measurement, so the hammer ball The ball is not suitable for measuring the verticality of tall buildings;

[0005] 2. When using laser to measure the verticality of high-rise buildings, although the well-known optical principles can be used for measurement, if the instrument is accidentally dropped or damaged unintentionally during the measurement process, the measurement accuracy of the instrument itself will be caused if people do not know it. There is an error in the change, which causes the instrument to always have an error in the measurement of high-rise buildings, which affects the accuracy of the measurement, and the current laser test instrument is also relatively expensive;

[0006] 3. When using infrared to measure the verticality of high-rise buildings, infrared is limited by distance, and infrared will also be affected by the surrounding environment during the measurement process, so infrared is more suitable for close-range measurement, not suitable for verticality measurement of high-rise buildings ;

[0007] 4. Using theodolite to measure also has the situation that the accuracy of the instrument is often inaccurate due to external reasons.
