Construction method of wedge-shaped composite discrete material pile
The invention relates to the technical field of discrete material pile construction, and discloses a construction method of a wedge-shaped composite discrete material pile, which comprises the following steps: S1, piling operation preparation; s2, along-rail gooseneck type rod hammers are used for ramming and reaming, and gravel is mixed with soil to form a retaining wall; s3, pile forming at the lower part; s4, forming a pile in the middle; s5, molding the upper pile body; s6, pile forming of the upper pile body; s7, pile top forming; and S8, a complete wedge-shaped discrete material pile body is formed. The wedge-shaped pile body with the large upper portion and the small lower portion is formed, the upper portion load pressure stress trapezoid transmission characteristic is formed, the pressure bearing area of the pile top is increased, meanwhile, the compactness and the compressive strength of soil between piles are promoted to be improved, the lateral restraining force generated by the discrete material pile body is promoted to be improved, and the multiple effects of synchronous improvement are achieved.
本发明涉及散体材料桩施工技术领域,公开了一种楔形复合散体材料桩的施工方法，包括以下步骤：S1、打桩作业准备；S2、顺轨鹅颈型棒锤夯击扩孔，碎石混合土壤形成护壁；S3、下部成桩；S4、中部成桩；S5、上部桩体成模；S6、上部桩体成桩；S7、桩顶形成；S8、形成完整的楔形散体材料桩体。本发明形成上大下小的楔形桩体，在形成上部荷载压应力梯形传递特色及增加桩顶承压面积的同时，促使桩间土密实度和抗压强度提高及对散体材料桩体所产生的侧向约束力的提升，得到同步提高的多重效果。
