摘　　要：孔道压浆质量的好坏是影响公路桥梁工程质量与安全的重要因素。对于较长的孔道,采用塑料波纹管辅助真空压浆施工工艺,用水灰质量比小于0.35的水泥浆,配合专用的压浆设备,由专业施工队伍严格按照标准操作工序进行压浆施工,可以保证压浆质量。文中以某大桥施工为例,介绍了塑料波纹管真空辅助压浆的技术要点。Duct grouting quality is an important factor influencing the quality and safety of bridges.For long duct,the grouting quality will be ensured fundamentally by using corrugated plastic pipe-assisted vacuum grouting construction technology,with the cement slurry whose water-cement ratio is less than 0.35,with dedicated grouting equipment and by the professional team in strict accordance with standard operating procedures for grouting construction.Taking a bridge as an example,the paper introduced the main poi...
