Cement mixing pile and method for reinforcing foundation in cold region
The invention belongs to the technical field of foundation reinforcement, and particularly relates to a cement mixing pile and method for reinforcing a foundation in a cold region. A connector capable of moving up and down is arranged on the rack, a group of hollow connecting shafts are mounted on the bottom surface of the connector, a driving mechanism for driving the connecting shafts to rotate is arranged in the connector, stirring blades are fixedly connected to the surfaces of the connecting shafts, and the tops of the connecting shafts are opened; a set of connecting grooves are formed in the side wall, close to the bottom face, of the connecting shaft, a feeding pipe is communicated with the interior of the connecting shaft, and a set of baffle rings are fixedly connected to the side wall of the rack through a support. The connecting shaft is driven by the driving mechanism to drill into the ground to start hole digging, when hole digging is finished, cement is injected from the opening end of the connecting shaft, meanwhile, the anti-freezing solution is injected from the feeding pipe, the anti-freezing solution and the cement are mixed, the anti-freezing solution can reduce the freezing point of water in the cement, and therefore the solidification time is shortened.
本发明属于地基加固技术领域，具体的说是一种寒区地基加固用的水泥搅拌桩及方法，包括机架；所述机架上设置有可上下移动的连接器，所述连接器的底面安装有一组空心的连接轴，所述连接器内设置有驱动连接轴转动的驱动机构，所述连接轴的表面固定连接有搅拌叶片，所述连接轴的顶部开口设置，所述连接轴靠近底面的侧壁开设有一组连接槽，所述连接轴内连通有进料管，所述机架的侧壁通过支架固定连接有一组挡环；通过借助驱动机构驱动连接轴钻入地内开始挖孔，挖孔结束时，从连接轴的开口端注入水泥，并同时从进料管注入防冻液，让防冻液与水泥混合，防冻液可以降低水泥中水分的凝固点，从而缩短凝固时间。
