水泥搅拌桩的施工工艺及控制措施

水泥搅拌桩是我国在20世纪发展起来的地基处理新技术,它是通过特制的深层搅拌机械在地层深部就地将软土和水泥强制拌和,使软土硬结而提高地基强度。这种方法适用于软弱地基的处理,对于淤泥质土、粉质粘土及饱和性土等软土地基的处理效果显著,处理后可以很快投入使用,施工速度快,在施工中无噪音、无振动,对环境无污染,投资省。本文主要介绍水泥搅拌桩现场管理、施工控制要点、控制方法,并总结了几点体会。

The Construction Technique and Control Measures of Cement Agitation Pile

Cement mixing pile is the foundation treatment technology developed in the 20th century,it is through a special machine in the formation of deep mixing of deep soft soil and cement in situ so that with the soft soil indurations and increased strength.This method is suitable for soft ground treatment and has significant treatment effect for the muddy soil,silty clay and saturated soft foundation.After treatment,it can be quickly put to use,work fast,no noise,no vibration in the construction,no pollution to environment;little investment.In this paper,on-site management of cement,construction control points,control methods are introduced and the experience is summarized.
