The invention relates to a cement stirring grouting reinforcement treatment method for a deep soft soil foundation, which comprises the following steps that a drill bit is provided, a grouting opening is formed in the side wall of the drill bit, and a cover plate is rotatably connected to the side wall of the drill bit and used for opening or closing the grouting opening; determining a pile position; the stirring pile machine is started, and the drill bit sinks to the preset depth through positive circulation stirring; the drill bit lifts the drill in a reverse circulation mode and sprays concrete slurry through a grouting opening; and the drill bit repeatedly ascends and sinks for stirring until the pile is formed. According to the cement mixing grouting reinforcement treatment method for the deep soft soil foundation, the amount of cement paste at the bottom of the drilled hole can be guaranteed, and therefore the strength of a cement mixing pile is guaranteed.
本申请涉及一种深层软土地基的水泥搅拌注浆加固处理方法，包括以下步骤：提供钻头，所述钻头的侧壁开有注浆口，所述钻头的侧壁转动连接有盖板，用以打开或闭合所述注浆口；确定桩位；启动搅拌桩机，使钻头正循环搅拌下沉至预设深度；钻头反循环提钻并通过注浆口喷射混凝土泥浆；使钻头重复上升和下沉搅拌，直至成桩。该深层软土地基的水泥搅拌注浆加固处理方法可以保证钻孔的底部水泥浆的量，从而保证水泥搅拌桩的强度。
