公路工程钻孔桩灌注混凝土质量通病及防治措施研究

Research on Common Quality Problems and Prevention Measures ofBored Pile Grouting Concrete in Highway Engineering

为提高公路工程钻孔桩施工效果,加强对灌注混凝土质量通病的防治,文章具体分析了钻孔桩在灌注混凝土工序环节中存在的导管进水、钢筋笼上浮、导管堵管等质量通病,深入探讨了形成质量问题的原因,并在此基础上提出了对各类质量通病的有效防治措施,旨在预防和减少质量问题,为公路工程基础施工质量提供保障。

In order to improve the construction effect of bored piles in highway engineering and strengthen the prevention and control of common quality problems in grouting concrete,this paper analyzes common quality problems of bored piles in the process of grouting concrete,such as pipe water inflow,steel cage floating and pipe plugging,and probes into the causes of quality problems.On this basis,effective prevention and control measures for various quality problems are put forward,aiming at preventing and reducing quality problems and providing guarantee for the quality of highway engineering foundation construction.
