Tower crane concrete foundation construction method based on soft soil layer natural foundation
The invention provides a tower crane concrete foundation construction method based on a soft soil layer natural foundation. The tower crane concrete foundation construction method comprises the steps of tower crane foundation site selection, geological soil layer analysis, triaxial deep stirring pile soil body reinforcement parameter determination, triaxial deep stirring pile reinforcement soil body construction, earth excavation, tower crane foundation construction, foundation bottom plate construction, tower crane installation and tower crane monitoring and testing. In the selected construction range of the tower crane concrete foundation, the three-shaft mixing piles are adopted in advance to reinforce the soil body and replace the soft soil layer in the original position, the influence of the soft soil layers with different elevations on the tower crane foundation is avoided, meanwhile, a larger interval is provided for elevation selection of the tower crane foundation, and the construction efficiency of the tower crane foundation is improved. The requirement for the foundation bearing capacity needed by the tower crane foundation is met, the condition limitation that a natural foundation is originally selected for a fixed foundation is broken through, the use range of the fixed foundation is expanded, the overall safety performance of tower crane construction is guaranteed, meanwhile, the engineering amount of tower crane pile construction can be reduced, and the economic effect of reducing cost is achieved.
本发明提供了一种基于软质土层自然地基的塔吊砼基础施工方法，包括：塔吊基础选址，地质土层分析，三轴深搅桩土体加固参数确定，三轴深搅桩加固土体施工，土方开挖，塔吊基础施工，基础底板施工，塔吊安装，塔吊监测测试。本发明在选定的塔吊砼基础的施工范围内，预先采用三轴搅拌桩加固土体，置换原位置的软质土层，避免了因不同标高软质土层对塔吊基础带来的影响，同时对塔吊基础在标高的选择上提供更大的区间，满足了塔吊基础所需的地基承载力要求，突破固定式基础原本选择自然地基的条件限制，扩大固定式基础的使用范围，保证塔吊施工整体的安全性能，同时也可减少塔吊桩施工的工程量，达到降本的经济效果。
