Pile sinking method of tubular pile
The invention relates to the field of pile sinking technologies, in particular to a tubular pile sinking method which comprises the following steps that S1, a pile hole is formed from the earth surface to the stratum; s2, filler is injected into the pile hole, and the volume of the filler is large enough to enable the filler to overflow from the pile hole after the tubular pile sinks into the bottom of the pile hole; s3, the pipe pile is sunk into the bottom of the pile hole, and the filler overflows out of the pile hole; and S4, after the filler is solidified, pile sinking is completed. The filler is injected into the pile hole before the pipe pile, a sand cushion layer does not need to be laid at the bottom of the pile hole, the end, sunk into the pile hole, of the pipe pile is further plugged through the pile end plug, the situation that the filler rushes into the pipe pile is avoided, and the construction procedure of pile sinking operation is simplified. In addition, the defects that according to an existing pile sinking method of the prestressed concrete pipe pile, the earthwork operation area is too large, the price of purchased filler is high, and the civil construction cost is too high are overcome.
本发明涉及沉桩技术的领域，尤其是涉及一种管桩的沉桩方法，该方法包括以下步骤：S1、自地表向地层开设桩孔；S2、向所述桩孔注入填料，所述填料的体积足以使其在所述管桩沉入所述桩孔的底部后从所述桩孔中溢出；S3、将所述管桩沉入至所述桩孔底部，所述填料从所述桩孔内溢出；S4、待所述填料凝固，沉桩完成。本发明填料先于管桩注入桩孔内，桩孔底部不需要再铺设砂土垫层，管桩沉入桩孔内的一端还通过桩端封堵进行封堵，避免了填料涌入管桩内的情形，使得本发明简化了沉桩作业的施工工序。并且，本发明还克服了现有的现有预应力混凝土管桩的沉桩方法土方作业面积过大，外购回填料价格昂贵，土建施工费用过高的缺陷。
