Abstract

The invention discloses an automatic paving method based on laser scanning and satellite positioning. The method comprises the following steps: importing design data: importing the design data of a paving pavement into a controller of a paver, and taking the design data as a basis for the comparison and correction of the paving pavement in actual paving; planning measurement stations: planning a plurality of monitoring control stations at two sides of a paving roadbed, and arranging laser emitters and/or differential satellite positioning receivers at the monitoring control stations; and performing real-time measurement paving: when the paver is used for paving operation, sending information to a resolver by the laser emitters and the differential satellite positioning receivers, transmiting the information to the controller by the resolver, and adjusting the direction of a screed correspondingly by the controller, so that the paving pavement generates gradient and elevation changes, pavement fluctuation is made up, and the pavement flatness and thickness required by design are achieved. The automatic control level of pavement paving is improved, the control precision is high, andmulti-machine joint paving is realized.

Description

technical field [0001] The invention relates to the field of foundation paving, in particular to an automatic paving method based on laser scanning and satellite positioning. Background technique [0002] In the prior art, roadbed paving mostly uses slipper sensors and sonar sensors to track the Luliang or datum line erected by surveyors for on-site construction to realize the control of paving thickness and smoothness. During construction, many on-site personnel are required to carry out benchmarking During the erection and pavement pre- and post-measurement work, monitoring and control cannot be implemented during the paving process, and rework often occurs due to incorrect benchmark setting. On-site coordination is time-consuming and labor-intensive, and the accuracy of paving is also difficult to achieve high standards , especially in the paving construction of expressway pavement and airport pavement with large roadside width and long distance.
