Method for reinforcing soft soil foundation through cement mixing piles
The invention provides a method for reinforcing a soft soil foundation by using a cement mixing pile, which belongs to the technical field of pile hole planning and comprises the following steps of: constructing a corresponding digital model according to a drill rod and structures and materials of a plurality of mixing blades on the drill rod; planning the initial shape of the pile hole according to the detection result of the foundation; and according to the overall design specification, the inner diameter of the corresponding position of the pile hole is increased, and a construction route in the stratum is generated in combination with the model. Controlling the movement speed and direction of the drill rod and the plurality of stirring blades in the stratum by taking the construction route as a reference; and after the stirring blades reach the designated positions, the distance between the stirring blades and the drill rod is changed to adjust the movement radius of the stirring blades, and therefore the inner diameter of the formed pile hole is changed. And after construction is completed, concrete pouring and stirring are conducted, and finally construction of the stirring pile is completed. According to the method for reinforcing the soft soil foundation through the cement mixing piles, the bearing capacity of the mixing piles is improved, sedimentation of the mixing piles is reduced, and the construction quality is improved.
本发明提供了水泥搅拌桩加固软土地基方法，属于桩孔规划技术领域，包括：根据钻杆和钻杆上多个搅拌叶片的结构和材质构建对应的数字模型。根据地基的探测结果规划出桩孔的初步形状；根据整体的设计规格，增大桩孔对应位置的内径并结合模型生成在地层内的施工路线。以施工路线为基准在地层内控制钻杆和多个搅拌叶片运动的速度和方向；当搅拌叶片达到指定位置后，改变搅拌叶片与钻杆之间的间距以调整搅拌叶片的运动半径，从而改变形成的桩孔的内径。在施工完成后进行混凝土的浇筑和搅拌，最终完成搅拌桩的施工。本发明提供的水泥搅拌桩加固软土地基方法提高了搅拌桩的承载能力，降低了搅拌桩的沉降，提高了施工质量。
