Roadbed earthwork filling precise construction system based on Beidou technology

Abstract

The invention discloses a subgrade earthwork filling precise construction system based on the Beidou technology, and relates to the technical field of earthwork subgrade filling construction. According to the subgrade earthwork filling precise construction system based on the Beidou technology, engineering design data are converted into a three-dimensional digital model, calculation data are distributed to all engineering vehicles according to a certain sequence, the positions of soil unloading points are distributed, construction machines are commanded to reach the correct positions, and the construction efficiency is improved. A brand new control mode with absolute coordinates X and Y as references is adopted, traditional procedures of measurement, piling, grid drawing, lime scattering and the like are abandoned, the problem of soil unloading of a large number of dump trucks is solved at a time, a large amount of field measurement work is saved, operators are liberated, and the working efficiency is improved. And on-site construction management personnel can organize and manage the soil unloading procedure only on a computer, so that engineering construction in the traditional sense is converted into digital construction, and construction control is precise.

Description

technical field [0001] The invention relates to the technical field of earthwork roadbed filling construction, in particular to a precision construction system for roadbed earthwork filling based on Beidou technology. Background technique [0002] The traditional construction method is to unload the soil grid grid before filling the roadbed, and use the grid grid to control the soil unloading position. On-site technicians calculated the paving area of ​​each vehicle based on the compaction degree, loose paving coefficient and other data obtained in the test section, according to the loading capacity of each vehicle, and then calculated the grid size according to the filling width. Due to the inconsistent filling width of each layer, repeated calculations are required. Then, according to the calculated size, the technicians use a steel ruler to stake out the size on site, set up signs, organize personnel to pull out the grid lines, and use lime to mark them. After the grid, ...

Problems solved by technology

[0003] The above-mentioned traditional construction methods require a lot of manpower, long time, and large operation restrictions. For this reason, a precision construction system for subgrade earthwork filling based on Beidou technology is proposed, which converts engineering design data into a 3D digital model, and calculates the data. Allocate to each engineering vehicle according to a certain sequence, allocate the position of the unloading point, and direct the construction machinery to reach the correct position. The new control method based on absolute coordinates X and Y eliminates the need for measurement, piling, square drawing, Lime spreading and other traditional processes have solved the problem of unloading a large number of dump trucks at one time, saved a lot of on-site measurement work, liberated the operators, and the on-site construction management personnel can realize the unloading process only on the computer. Organization and management, transforming traditional engineering construction into digital construction, and realizing precise construction control
