Abstract

L'invention concerne un procédé de réparation et de construction de chaussée à rupture de pierre à résonance pour une route interne d'installation. Le procédé comprend : l'aspersion d'eau sur une file qui doit être rompue à l'aide d'un véhicule d'aspersion d'eau avant la rupture, et la régulation de la fréquence de vibration du marteau de telle sorte qu'elle est entre 44 Hz et 45 Hz, proche de la fréquence inhérente d'un panneau de ciment, de façon à exciter la résonance du panneau de ciment, de telle sorte que le panneau de béton de ciment est facilement rompu ; la réalisation d'une rupture de pierre à résonance dans l'ordre à partir de files latérales jusqu'à une file intermédiaire ; et, après que la rupture de pierre a été achevée, la réalisation d'un compactage par une machine de compactage, et, avant le compactage, une couche de film d'eau étant formée sur la surface de particules de pierre concassées classées après la rupture de pierre à l'aide d'une aspersion d'eau, et la couche de film d'eau sur la surface des particules ayant un effet de lubrification pendant le compactage, de façon à faciliter ainsi le mouvement de verrouillage mutuel des particules, de telle sorte que la compacité après le compactage peut être améliorée. Par le procédé, la construction est pratique et l'efficacité de travail est élevée.
