浅谈水泥搅拌桩在公路深厚软基处理中的应用

Application of Cement Mixing Pile in Deep Soft Foundation Treatment in Highway Engineering

水泥搅拌桩具有加筋软土厚度大,施工方便,成本低,基础处理效果好的特点。本文结合工程实际,根据场地的工程地质、软土层分布等情况,通过现场工艺研讨优化了成桩工艺参数,探讨了影响水泥搅拌桩强度的因素,并从水泥掺量管理,设备工艺管理和桩身质量检测等方面提出了施工管理的控制措施。

Cement mixing pile has the characteristics of large thickness of reinforced soft soil, convenient construction, low cost and good foundation treatment effect. In this paper, according to the engineering geology and soft soil distribution of the site, the process parameters of pile-forming are optimized through on-site technological discussion, the factors affecting the strength of cement mixing pile are discussed, and the control measures of construction management are put forward from the aspects of cement admixture management, equipment technology management and pile quality detection.
