Method for controlling pile-forming perpendicularity of vibro-replacement stone column under action of dynamic load
The invention belongs to the technical field of gravel pile forming construction, and particularly relates to a vibro-replacement gravel pile forming perpendicularity control method under the action of dynamic load, which comprises the following steps: determining the position of a gravel pile according to a designed drawing; according to the position of the gravel pile, a crane is moved to a proper position on one side of the gravel pile, a proper vibroflot is selected according to the specification of the gravel pile, and then a lifting ring hook on the vibroflot is hung on a universal vertical heavy hook of the crane; and an infrared verticality measuring instrument is mounted at a proper position, close to one side of the vibroflot, on the crane. According to the method, the phenomenon that the perpendicularity of the gravel pile does not meet the requirement due to the factors that the vibroflot is not perpendicular and the descending speed is too high in the descending process can be avoided, and therefore the economic losses such as construction period loss and material waste caused by the fact that the gravel pile diameter is too large and needs to be designed and checked again are avoided; and therefore, the gravel pile forming quality under the dynamic load effect is guaranteed.
本发明属于碎石桩成桩施工技术领域，尤其是涉及一种动荷载作用下振冲碎石桩成桩垂直度控制方法，包括依据设计的图纸，确定碎石桩位置；根据所述碎石桩的位置，将吊车移动至碎石桩一侧的合适位置，并根据所述碎石桩规格选用合适的振冲器，然后将所述振冲器上的吊环钩挂在所述吊车的万向垂重钩上；在所述吊车上靠近所述振冲器一侧的合适位置安装红外线测垂仪。本发明既能解决因振冲器下降过程中的不垂直和下降速度过快的因素，造成碎石桩垂直度不符合要求的现象，从而避免因碎石桩桩径过大而需要设计重新验算，造成工期损失，还会造成材料浪费等经济损失，进而保证动荷载作用下碎石桩成桩质量。
