夯扩沉管灌注桩事故分析及加固处理

Accident Analysis and Strengthening Treatment of Sinking Tubular and Expanded Placing Pile

桩身混凝土灌注过程中,发现混凝土充盈系数过大,混凝土流失过快,针对质量事故产生的原因进行了分析,并采取了加固措施,实践表明,效果良好。

Concrete filling coefficient is large, concrete is washed away fast in the pile body concrete process, the cause of quality accident is analysed. Meanwhile,strengthening measures are adopted,the result shows that it has good effect.
