AI Technical Summary

Technical Problem

Traditional road rollers cannot adapt to the curvature of the V-shaped trench arch roadbed during construction, resulting in uneven contact pressure and uneven compaction. Furthermore, the direction of the excitation force is fixed and cannot match the arched surface, affecting construction efficiency and structural stability.

Method used

An adjustable arc-shaped compaction plate is adopted, which integrates real-time arc recognition, dynamic curvature adjustment and normal synchronous excitation functions to achieve active fitting and precise vibration of the arched filling surface. Through the combination of the arc-shaped compaction module and the excitation module, uniform compaction of the entire cross section is achieved.

Benefits of technology

It achieves high-precision and high-efficiency compaction of V-shaped trench arch roadbed, eliminates compaction dead corners and unevenness, and improves construction quality and structural stability.

Abstract

The application discloses a curved surface self-adaptive compaction method for V-shaped ditch arched roadbed, and aims at the limitations of traditional road rollers in geometric adaptation and power transmission in arched roadbed filling areas.The core of the device is that the curved surface fitting technology of an adjustable circular arc compaction plate is adopted, three functions of integrated radian real-time identification, curvature dynamic adjustment and normal synchronous excitation are realized, active fitting and accurate excitation of the arched filling surface are realized, uneven compaction, low efficiency and structure disturbance caused by geometric mismatch, excitation direction deviation and forming control loss of traditional rigid road rollers are fundamentally overcome while full-section uniform compaction of the arched filling surface is realized, and therefore a high-precision and high-efficiency special equipment solution is provided for arched structure construction of V-shaped ditch high fill roadbed in a collapsible loess area.
