Construction method of fiber reinforced curing agent mixing pile suitable for sludge foundation pit support
The invention relates to the technical field of sludge foundation pit supporting, and discloses a fiber reinforced curing agent mixing pile construction method suitable for sludge foundation pit supporting, which comprises the following construction steps: 1) leveling a construction site, and determining the pile position of a construction mixing pile; (2) preparing a fiber reinforced curing agent, wherein the fiber reinforced curing agent is formed by mixing cement, mineral powder, fly ash, gypsum, polyvinyl alcohol short fibers and water; (3) a stirring drill rod of the slurry spraying pile machine is used for drilling and stirring the soil body downwards at the pile position, in the soil layer drilling process of the stirring drill rod, a slurry spraying pipe synchronously sprays a fiber reinforced curing agent to the soil body till the stirring drill rod drills to the set depth, and then the stirring drill rod is lifted upwards to the set height; in the process that the stirring drill rod is lifted upwards in the soil layer, the stirring drill rod synchronously drills and stirs the soil body, and a slurry spraying opening of the slurry spraying pipe synchronously sprays a fiber reinforced curing agent into the soil body; and (4) the step (3) is repeatedly operated and constructed for set times, and the fiber reinforced curing agent and the soil body are mixed to form the stirring pile.
本发明涉及淤泥基坑支护的技术领域，公开了适用淤泥基坑支护的纤维加筋固化剂搅拌桩施工方法，包括以下施工步骤：1)、平整施工场地，确定施工搅拌桩的桩位；2)、配置纤维加筋固化剂，纤维加筋固化剂由水泥、矿粉、粉煤灰、石膏、聚乙烯醇短纤维以及水体混合而成；3)、利用浆喷桩机的搅拌钻杆在桩位朝下钻进搅拌土体，搅拌钻杆在土层钻进的过程中，喷浆管朝土体同步喷射纤维加筋固化剂，直至搅拌钻杆钻至设定深度后，再朝上提升搅拌钻杆至设定高度；搅拌钻杆在土层朝上提升的过程中，搅拌钻杆同步钻动搅拌土体，喷浆管的喷浆口同步往土体中喷射纤维加筋固化剂；4)、重复操作施工步骤3)至设定次数，纤维加筋固化剂与土体混合形成搅拌桩。
