The invention provides a construction method for improving soft foundation soil layer bearing capacity, which comprises the following steps: selecting a soil layer position, taking out sample soil, and testing; measuring and setting out; a drilling machine of the stirrer is aligned with the pile position, and a pile machine body of the stirrer is leveled; feeding slurry while stirring and sinking; after slurry sprayed by the deep stirrer sinks to the depth of the pile foundation, the deep stirrer stays at the hole bottom for stirring and slurry spraying, and a stirring head is reversed from the pile end for lifting and stirring; and the guniting stirring sinking step and the guniting stirring lifting step are repeated. The curing agent and the soil body are stirred and mixed into a whole through a deep stirring method to improve the bearing capacity of the foundation, original soil is utilized to the maximum extent, disturbance to the surrounding soil body is small, and the problems that an existing soft soil area treatment mode is complex, and the construction period is long are solved.
本发明提供了一种用于提高软弱地基土层承载力的施工方法，该施工方法包括如下步骤：选取土层位置，并取出试样土，进行试验；测量放样；将搅拌机的钻机对准桩位，调平搅拌机的桩机机身；在搅拌下沉同时送浆；深层搅拌机喷浆下沉到桩基深度后，停留在孔底搅拌喷浆，将搅拌头自桩端反转提升搅拌；重复喷浆搅拌下沉步骤和喷浆搅拌提升步骤。本发明通过深层搅拌法将固化剂和土体搅拌混合为一体来提高地基承载力，最大限度的利用了原土，对周围土体的扰动比较小，解决了现有软土地区处理方式复杂、施工周期长的问题。
