水泥搅拌桩在软土路基中的施工工艺

Construction technology of cement mixing pile in soft soil foundation

以某工程为实例,阐述了在特殊软土地层中软基处理施工方法的选择原则,对具体的施工工艺进行了介绍,针对施工中遇到的喷浆中断、喷浆量不够、钻进受阻、钻进速度不稳等问题提出了解决的措施,以保证路基的稳定性。

Based on the engineering example,the paper describes soft foundation construction methods selecting principles in special soft soil lay-er,introduces its specific construction technology,and puts forward solving measures to construction problems including spray interrupt,insuffi-cient spray amount,drilling barricade,and instable drilling speed and so on,with a view to guarantee the subgrade stability.
