Prefabricated packing expanding key type excavation foundation for power transmission line and construction method thereof
The invention discloses a prefabricated packing expanding key type excavation foundation for a power transmission line and a construction method thereof. The foundation comprises concrete assemblies,prestressed reinforcements and prefabricated root keys, wherein the concrete assemblies are packing expanding components, the middles of the concrete assemblies are of hollow structures, a plurality of through reserved prestress holes are formed in the concrete assemblies in the height direction, a plurality of root key reserved holes are formed in the concrete assemblies in the bottom surface direction, the plurality of concrete assemblies are sequentially stacked in a foundation pit, the prestressed reinforcements penetrate through the corresponding reserved prestress holes in the multiple concrete assemblies to enable the concrete assemblies to be assembled to form a foundation body, and the prefabricated root keys penetrate through the root key preformed holes to be inserted into the side wall of the foundation pit. According to the prefabricated packing expanding key type excavated foundation, the construction period can be remarkably shortened, the synergistic effect of the foundation and a soil body is brought into full play, the horizontal load resistance and the overturning resistance of the foundation are improved, and the construction safety risk and the construction cost are reduced.
本发明公开一种用于输电线路的预制扩盘根键式掏挖类基础及其施工方法，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扩盘构件，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，沿底面方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。本发明提供的预制扩盘根键式掏挖类基础，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。
