Three-shaft mixing pile construction method for deep and thick mud layer of foundation pit
The invention relates to the field of three-shaft mixing pile reinforcement construction, in particular to a foundation pit deep and thick sludge layer three-shaft mixing pile construction method which comprises the steps of foundation pit reinforcement layering, parameter determination and reinforcement inspection, and according to foundation pit reinforcement layering, a reinforcement area is layered according to the excavation depth of a foundation pit; the parameter determination is to determine construction parameters of three-axis reinforcement of each layer; and the reinforcing inspection is to verify the reinforcing compressive strength of each layer of the foundation pit through core drilling sampling. The reinforced foundation pit is layered and segmented in advance, the construction parameter values suitable for the structural characteristics of the reinforced foundation pit are selected in the construction process, the pile forming quality of all layers is guaranteed, cement waste is avoided, and the construction cost is saved while the construction quality is guaranteed.
本发明涉及三轴搅拌桩加固施工领域，特别涉及一种基坑深厚淤泥层三轴搅拌桩施工方法，包括基坑加固分层、参数确定、加固检验步骤，所述的基坑加固分层为根据基坑开挖深度对加固区进行分层；所述的参数确定为对每层三轴加固的施工参数进行确定；所述的加固检验为通过钻芯取样，验证基坑各分层的加固的抗压强度。通过预先对加固基坑进行分层分段，在施工中选定适宜其结构特征的施工参数值，不仅保证各分层的成桩质量，而且有利于避免水泥浪费，在保证施工质量的同时节约了施工成本。
