Non-stop asphalt multi-machine continuous paving method applying 3D automatic paving system

Abstract

The invention provides a non-stop asphalt multi-machine continuous paving method applying a 3D automatic paving system. The method comprises the following steps of: 1, data preparation: obtaining paper and CAD design data from a design unit, extracting control point and benchmark point information in the paper and CAD design data, converting the control point and benchmark point information into arecognizable data format, selecting a laser erection position in combination with the layout condition and the construction direction of a construction site, and obtaining accurate position information, 2, carrying out data design, taking the recognizable data format obtained in the step 1 as a construction reference basis, and carrying out conversion from data to a construction result through GNSS RTK, domain laser, radio station communication and a hydraulic control method, and 3, carrying out non-stop asphalt multi-machine continuous paving operation. The butt joint of the MMGPS 3D pavingautomatic and control technology from theory to practice is completed, and the application of the MMGPS 3D paving automatic and control technology in the actual engineering paving process is perfected.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a non-stop asphalt multi-machine continuous paving method using a 3D automatic paving system. Background technique [0002] In the past asphalt construction methods, a 2D automatic control leveling system is usually used, which is implemented by erecting balance beams or sliding shoes, with metal beams, wire ropes, or the original ground as the reference. During the paving process, the metal beams or datum lines erected by the personnel are usually measured by the slip shoe sensor and the sonar sensor tracker for on-site construction to realize the control of the paving thickness and smoothness. During the construction, a lot of on-site personnel are required to carry out the erection of the benchmark and the pre- and post-measurement of the pavement, and many workers are also required to assist in the measurement [0003] The mmGPS 3D paving automatic control syst...

Problems solved by technology

[0004] However, since the MMGPS 3D paving automation and control technology is not yet perfect, it cannot be combined with the actual paving process of the project, so there is no grounding for any engineering project
