Pier circular deep foundation and construction method thereof
The pier circular deep foundation comprises a circular deep foundation body and a hole guide wall arranged around the whole circle of a hole of the circular deep foundation body, and the circular deep foundation body comprises a soil layer section corrugated steel plate retaining wall structure and a rock layer section sprayed concrete retaining wall structure fixedly connected with the soil layer section corrugated steel plate retaining wall structure; the foundation is different from a cast-in-place concrete retaining wall deep foundation, segmented pouring in the vertical direction of the foundation is not needed, weak parts at the joint of the segments do not exist, and the overall stability is good; compared with a steel casing retaining wall deep foundation, the corrugated steel plate is in a concave-convex shape and is tightly connected with surrounding soil through grouting, and the stress performance of the foundation is good.
一种桥墩圆形深基础及施工方法，包括：圆形深基础本体和环圆形深基础本体洞口整圈设置的洞口导向墙，所述圆形深基础本体包括土层段波形钢板护壁结构和与土层段波形钢板护壁结构固定连接的岩层段喷射混凝土护壁结构；本发明区别于现浇混凝土护壁深基础，无需沿基础竖向分节段浇筑，不存在节段连接处薄弱部位，整体稳定性较好；与钢护筒护壁深基础相比，波形钢板外形为凹凸形，并通过注浆与周围土体紧密连接，基础受力性能较好。
