Construction method of precast pile foundation and precast pile foundation
The invention relates to the technical field of building construction, and provides a construction method of a precast pile foundation and the precast pile foundation. The construction method comprises the following steps that an assembled precast pile is settled to a target position; the connecting base is installed at the top end of the precast pile; the low-rigidity material layer is laid in a cavity defined by the connecting base and the top end of the precast pile; and the cushion layer is poured on the periphery of the connecting base, and the foundation is poured on the cushion layer. The low-rigidity material layer in the adopted precast pile foundation can effectively prevent the foundation located above the cushion layer from making direct contact with the top ends of the precast piles, the precast pile foundation which is located below the skirt room area and does not resist pressure is utilized, and the uniform settlement amplitude of the high-rise building area and the skirt room area between the wet season and the dry season is reduced; accordingly, the stability of the foundation of the skirt room area is guaranteed, and the safety of the skirt room area is improved.
本发明涉及建筑施工技术领域，提供一种预制桩基础的施工方法及预制桩基础，所述施工方法包括如下步骤：将组装后的所述预制桩沉降至目标位置处；将所述连接座安装于所述预制桩的顶端；在所述连接座与所述预制桩的顶端围成的腔体内铺设所述低刚度材料层；在所述连接座的外周浇筑所述垫层，在所述垫层上浇筑所述基础。本发明采用的预制桩基础中的低刚度材料层可有效阻止处于垫层上方的基础与预制桩的顶端直接接触，利用裙房区域下方具有不抗压作用的预制桩基础，减少丰水期与枯水期之间高层建筑区域与裙房区域的沉降均匀幅度，相应地保证裙房区域的地基基础的稳定性，提高裙房区域的安全性。
