在加固处理软土地基工程中经常采用的是水泥搅拌桩技术,它利用专业的机械把水泥注入需要处理的软土地上,运用水泥加固土体的物理化学反应过程的原理,用机械的力量促使土体上下搅拌并达到均匀状态,最后土和水泥发生了水分和分解反应、固结软土、提高地基的承载力和强度。本文将分析水泥搅拌桩的特点和作用,根据杭州市长睦大型居住区天都路道路工程软土地基实际案例,从具体工艺、设备机械、试验检验和质量控制等方面分析水泥搅拌桩在施工中的具体应用。
Often used in the consolidation of soft soil foundation engineering is the cement mixing pile technology, which uses professional machinery to inject the cement into the soft soil needs to be treated, the principle of using cement to reinforce the physical and chemical reaction process of soil, using mechanical force to promote The soil is stirred up and down and reaches a uniform state. Finally, moisture and decomposition reactions occur between the soil and the cement, consolidating the soft soil and increasing the bearing capacity and strength of the foundation. This paper will analyze the characteristics and functions of cement mixing piles. According to the actual case of soft soil foundation of Tiandu Road, a large residential area in Hangzhou, this paper analyzes the concrete mixing piles during construction from the aspects of concrete technology, equipment and machinery, test and quality control, In the specific application.
