Steel pipe pile resonance-free construction method suitable for soft soil foundation
The invention relates to the technical field of building pile foundation engineering, in particular to a steel pipe pile resonance-free construction method suitable for a soft soil foundation, which comprises the following steps: paving a sand cushion in a construction site of the soft soil foundation, and arranging a transverse drainage channel in the sand cushion; a steel pipe pile with a plastic drainage plate on the periphery is implanted into the soft soil foundation through a high-frequency resonance-free pile sinking construction technology, the plastic drainage plate is implanted into the soft soil foundation along with the steel pipe pile, and a vertical drainage channel is formed in the pile sinking process; the plastic drainage plate is embedded into the sand cushion layer, the vertical drainage channel formed by the plastic drainage plate is communicated with the transverse drainage channel, and rapid dissipation of excess pore water pressure is achieved. The resonance-free pile sinking method has the advantages of being high in construction speed, small in influence on the surrounding environment, low in noise, small in slurry pollution and the like, and meanwhile the technical problems that after resonance-free pile sinking is conducted in the soft soil area, excess pore water pressure dissipation is slow, and the pile bearing capacity recovery time is long are solved.
本发明涉及建筑桩基工程技术领域，尤其是一种适用于软土地基的钢管桩免共振施工方法，在软土地基的施工场地内铺设砂垫层并在所述砂垫层内设置横向排水通道；通过高频免共振沉桩施工工艺在所述软土地基内植入外围具有塑料排水板的钢管桩，所述塑料排水板随着所述钢管桩一并植入所述软土地基并在沉桩过程中形成竖向排水通道；将所述塑料排水板埋入所述砂垫层并使其形成的所述竖向排水通道与所述横向排水通道连通，实现超孔隙水压力的快速消散。本发明的优点是：具有免共振沉桩方法施工速度快、对周边环境影响小、噪音小、泥浆污染小等优势，同时克服了软土地区免共振沉桩后超孔隙水压力消散慢、桩承载力恢复时间长的技术难题。
