在公路施工技术逐渐更新的过程中,很多先进的施工技术得到了推广运行,让公路工程施工效率大幅度上升。从最近几年的施工情况看,真空灌浆技术是公路工程中常用的技术,其摆脱了传统压力灌浆技术的不足,在施工工艺、操作流程、成本投资等方面都得到了改善。针对这一点,本文分析了真空灌浆技术的优势,并对其工艺流程深入研究。 In the process of gradual updating of highway construction technology, many advanced construction technologies have been popularized and run, so that the construction efficiency of highway projects has risen substantially. According to the construction situation in recent years, vacuum grouting technology is a commonly used technology in highway engineering. It has got rid of the shortage of traditional pressure grouting technology and has been improved in construction technology, operation flow and cost investment. In view of this, this paper analyzes the advantages of vacuum grouting technology, and in-depth study of its technological process.
