Composite pile foundation construction method for high-rise building
The invention discloses a composite pile foundation construction method for a high-rise building. The composite pile foundation construction method specifically comprises the following steps: (1) pile position setting-out is conducted, specifically, a lower pile hole position and depth are designed according to a field environment and a position condition of an underground buried object; (2) machine tool in-place adjustment is conducted, specifically, a drilling machine is arranged on the lower pile hole position, and a vertical shaft of the drilling machine is aligned with the lower pile hole position and is kept perpendicular to the lower pile hole position; (3) drilling is conducted; (4) slurry is prepared, specifically, water and ash are quantitatively applied according to a ratio of 1:1, and the slurry is filtered; (5) spraying operation is conducted, specifically, spraying operation is conducted from bottom to top to form jet grouting piles; and (6) pile pressing is conducted, specifically, PHC pipe piles are prefabricated, after the jet grouting piles are completed, after two hours, the multiple prefabricated PHC pipe piles are pressed into the jet grouting piles through a static press and a pile pressing machine before cement is not solidified. According to the construction method, the composite pile foundation of the high-pressure jet grouting and the prefabricated PHC pipe piles is formed, the bearing capacity of the pile foundation is greatly improved, the requirement of the high-rise building for the bearing capacity of a pile body is met, construction is easy and convenient, and the construction period is short.
本发明公开了用于高层建筑的复合桩基础施工方法，具体包括以下步骤：(1)桩位放样：根据现场环境和地下埋设物的位置情况，设计下桩孔位以及深度；(2)机具就位调整：在下桩孔位上设置钻机，钻机的立轴与下桩孔位对正并保持垂直；(3)钻孔；(4)制浆：按水灰1：1比定量施加并进行浆液过滤；(5)喷射作业：由下而上进行喷射作业形成旋喷桩；(6)压桩：预制PHC管桩，待旋喷桩完成后，间隔2小时，在水泥未凝固前用静压机通过压桩机将多根预制的PHC管桩压入旋喷桩内。依据本发明的施工方法，组成形成高压旋喷+预制PHC管桩的复合桩基础，大大提升了桩基础的承载力，满足高层建筑对桩身承载力的要求，施工简便，工期短。
