Spliced prefabricated root key type excavation foundation
The invention discloses a spliced prefabricated root key type excavation foundation. The spliced prefabricated root key type excavation foundation comprises concrete composite members, prestressed reinforcements and prefabricated root keys; the concrete composite members are of a disc structure, and the middles of the concrete composite members are of a hollow structure; a plurality of through reserved prestress holes are formed in the concrete composite members in the height direction, and a plurality of root key reserved holes are formed in the concrete composite members in the radial direction; the multiple concrete composite members are sequentially stacked in a foundation pit, and the prestressed reinforcements penetrate through the corresponding reserved prestressed holes in the multiple concrete composite members to enable the concrete composite members to be assembled to form a foundation body; and the prefabricated root keys penetrate through the root key preformed holes to beinserted into the side wall of the foundation pit. The construction period can be remarkably shortened, the synergistic effect of the foundation and a soil body is fully played, the horizontal load resistance and the overturning resistance of the foundation are improved, the construction safety risk and the construction cost are reduced, construction spoil and environmental damage are reduced, the concrete quality and the foundation durability are improved, and environmental protection is facilitated.
本发明公开一种拼接预制根键式掏挖类基础,包括混凝土组合件、预应力钢筋和预制根键;所述混凝土组合件为圆盘结构,其中部为空心结构;所述混凝土组合件沿高度方向设置有贯穿的若干预留预应力孔,沿径向设置有多个根键预留孔;多个所述混凝土组合件依次叠放在基坑内,所述预应力钢筋穿过多个混凝土组合件上对应的预留预应力孔使混凝土组合件装配组成基础主体;所述预制根键穿过所述根键预留孔插入基坑侧壁内。本发明可显著节约施工周期,充分发挥基础与土体的协同作用,提高基础的抗水平荷载和抗倾覆能力,降低施工安全风险和工程造价,减少施工弃土和环境破坏,提高混凝土质量和基础耐久性,有益于环境保护。
