Research on the Application of 3D Intelligent Paving Construction Technology for Water-stabilized Layer of Roadbed
The 3D intelligent paving automatic control system integrates a variety of positioning/sensing technologies,professional software and powerful control systems.The digital paving automatic control system consists of a GPS base station and a PZL-1 laser base station installed at the control point.The GPS differential signal and laser elevation information are transmitted to the MC-R3 receiver through the wireless data transmission station and the MC-R3 pair of receivers After the data is processed,the three-dimensional coordinate data is transmitted to the GX-60 control box in real time.The control box will compare the current three-dimensional coordinate information with the design card data in the control box,generate corresponding elevation correction information,and then the control box will generate the corresponding proportional drive signal,and drive the paver traction arm hydraulic cylinder through the hydraulic valve.The screed is adjusted in the corresponding direction to cause changes in slope and elevation of the paving surface,compensate for road fluctuations,and meet the paving design requirements.This article studies the key points of the 3D intelligent paving system,which is simple and convenient to operate,easy to promote and use,and brings huge benefits to engineering applications.
