Deep foundation pile with expanded head and construction method thereof
The invention discloses a deep foundation pile with an expanded head and a construction method thereof. The deep foundation pile comprises a pile body and the expanded head at the pile bottom. The expanded head sequentially comprises a cushion layer, a bottom step and a high step from outside to inside. The cushion layer is formed by extruding a filling material and then compacting a soil body inthe lower portion. The bottom step is formed by extruding a filling material. The high step is formed by tamping a concrete filling material. The construction method of the deep foundation pile with the expanded head is controllable in process, safe and reliable in quality and convenient to construct. The deep foundation pile with the expanded head is good in foundation expansibility, can be usedas an environment-friendly fabricated building to explore and innovate underground space geotechnical engineering, and conforms to the development direction of national environment-friendly buildings.
本发明公开了一种具有扩大头的深基础桩及其施工方法，包括桩身、桩底的扩大头，所述扩大头自外向内依次为垫层、底阶、高阶；所述垫层为填充料挤出后挤密下方的土体形成；所述底阶由填充料挤出形成；所述高阶由混凝土填充料夯实形成。本发明流程可控，质量安全可靠，施工方便。本发明基础扩展性能好，可作为绿色装配式建筑向地下空间岩土工程探索创新，符合国家绿色建筑的发展方向。
