Embodiment
[0018] RTK-based measurement and control method for engineering arbitrary curve sliding and translation refer to figure 1 , the steps are as follows:
[0019] 1) Large-scale building components are constructed on moving sliders on several sliding tracks. The sliding track can be any curve, and hydraulic thrusters are used to drive the sliding of large-scale building components;
[0020] 2) GNSS receivers are divided into mobile stations and reference stations. The number of GNSS receivers is N, and N is equal to the number of sliding orbits plus 1. One of the GNSS receivers is fixed on a known coordinate point as a reference station. The remaining N-1 GNSS receivers are fixed on the sliding objects in each track as mobile stations;
[0021] 3) The hydraulic propeller is controlled by the hydraulic station; the control computer controls the hydraulic station and the GNSS receiver through wireless signals, corrects the starting point, checks the working condition of the hydraul...

The invention discloses an RTK-based method for synchronous measurement and control of engineering arbitrary curve sliding and translation. The system includes: a hydraulic thruster, a sliding track, a hydraulic station, a GNSS receiver and a control computer. The large-scale building slip data on each track collected by the GNSS receiver is sent to the control computer by the wireless communication module, and the control computer controls the action of the hydraulic thruster after calculation by the control components to make the object move on the slip track. Using an RTK-based method for synchronous measurement and control of sliding and translation of arbitrary curves in engineering, during the sliding construction process, the displacement of each push point is synchronized, so that the entire structure is in a translational state, avoiding the stress of structural attachments, and protecting the overall stability. damaged.
Description
technical field [0001] The invention relates to the field of building construction, and specifically provides an RTK-based method for synchronous measurement and control of any engineering curve sliding and translation. Background technique [0002] At present, there are many large-scale venues in China, such as airports, railway stations, stadiums, etc., and the roofs used generally have relatively large spans, areas, and self-weights. With the traditional construction technology, multiple steel structure assembly platforms need to be built on the construction site. It is difficult to further improve the installation accuracy of the project, and the safety of construction operations is also low. In addition, it will cause a lot of waste of temporary support rods. At the same time, since the bearing capacity of the roof of the warehouse is only about 2.5 tons per square meter, and the overall roof is generally greater than 500 tons, it is not possible to use a large crane fo...
