Multi-section expanding disc prefabricated hollow excavation type foundation
The invention discloses a multi-section expanding disc prefabricated hollow excavation type foundation. The foundation comprises concrete composite members and prestressed reinforcements, a pluralityof through preformed holes are formed in the concrete composite members in the height direction, the multiple concrete composite members are sequentially stacked in a foundation pit, the prestressed reinforcements penetrate through the corresponding preformed holes in the multiple concrete composite members to enable the concrete composite members to be assembled into a foundation body, the concrete composite members are non-cylindrical expanding disc components, the middle parts of the concrete composite members are of hollow structures, and gaps between the concrete composite members and thefoundation pit are filled with cement paste or fine aggregate concrete. According to the multi-section expanding disc prefabricated hollow excavation type foundation, the synergistic effect of the foundation and a soil body can be given to full play, the vertical and horizontal bearing capacity and the lateral rigidity of the foundation can be improved, the construction time and the constructionperiod can be saved, the construction safety risk and the construction cost can be lowered, the construction spoil and environmental destruction can be reduced, the concrete quality and the foundationdurability can be improved, and environmental protection can be facilitated.
本发明公开一种多节扩盘装配式空心掏挖类基础，包括混凝土组合件和预应力钢筋；所述混凝土组合件沿高度方向设置有贯穿的若干预留孔；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孔使混凝土组合件装配组成基础主体；所述混凝土组合件为非圆柱体扩盘构件，其中部为空心结构；所述混凝土组合件与基坑之间间隙填充水泥浆或细石混凝土。本发明提供的多节扩盘装配式空心掏挖类基础，可充分发挥基础与土体的协同作用，提高基础的竖向、水平承载力和侧向刚度，节约施工时间和施工周期，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。
