Piling method for improving bearing capacity of single pile
The invention relates to the technical field of building construction, in particular to a piling method for improving the bearing capacity of a single pile, which comprises the following steps: fixing a target single pile through a guide device; the pile periphery soil body at the target piling position is measured, the initial soil body softness is obtained, and the initial falling speed of a piling hammer is determined according to the initial soil body softness; acquiring each actual single settlement depth of the target single pile, analyzing the actual single settlement depth, measuring the perpendicularity of the single pile to obtain actual target single pile perpendicularity, and determining whether to adjust the initial falling speed or not according to the actual target single pile perpendicularity to obtain a first falling speed; and on the basis that the settlement requirement is not met, the initial piling frequency is adjusted to obtain the first piling frequency, a second piling result is obtained on the basis of the first piling frequency, and the piling mode is adjusted according to the second piling result. Damage to soil around the pile is reduced by adjusting the falling speed and the piling frequency.
本发明涉及建筑施工技术领域，尤其涉及一种提高单桩承载力的打桩方法，包括：对目标单桩通过导向装置进行固定；测量目标打桩位置的桩周土体并得到初始土体松软度，根据初始土体松软度确定打桩锤的初始下落速度；获取目标单桩的各实际单次沉降深度，对实际单次沉降深度进行分析，测量单桩垂直度得到实际目标单桩垂直度，根据实际目标单桩垂直度确定是否调整初始下落速度，以得到第一下落速度；基于不满足所述沉降需求的情况，对初始打桩频率进行调节，以得到第一打桩频率，基于所述第一打桩频率获取第二打桩结果，并根据所述第二打桩结果调整打桩方式。本发明通过对下落速度和打桩频率的调整，以减少对桩周土体破坏。
