公路施工中水泥搅拌桩应用技术

水泥搅拌桩是公路施工中软基处理常用的一种技术,通过水泥的固化作用,让软土硬结,从而提高地基的承载力。该方法具有施工速度快、成本低、效果显著等优点,因而广泛被应用于公路工程软弱地基的处理。结合工程实际,对水泥搅拌桩的施工工艺及其质量控制进行阐述,以供参考。

Application Technology of Cement Mixing Piles in Highway Construction

Cement mixing pile is a common technology for soft foundation treatment in highway construc- tion. Its principium is hardening the soft soil by the solidification of cement in order to advance the bearing ca- pacity of foundation. The method has such advantages as high speed, low cost, prominent effect and so on, thus it is widely used in soft foundation treatment of highway engineering. Combining with practical engineering, the con- struction technique and quality control of cement mixing pile are expatiated on, which can be consulted by peers.
