Double-wall concrete open caisson structure and construction method thereof
The invention provides a double-wall concrete open caisson structure and a construction method thereof, and relates to the technical field of concrete open caissons. The double-wall concrete open caisson structure comprises a concrete inner wall, a concrete outer wall, a plurality of concrete partition walls and a plurality of reinforcing anchor rods, and a containing cavity is formed between the concrete outer wall and the concrete inner wall; the concrete partition walls are arranged in the containing cavity; the reinforcing anchor rods penetrate through the concrete inner wall and the concrete outer wall and extend outward in the radial direction of the concrete outer wall; and the lower end of the concrete outer wall is provided with a blade foot assembly, and the blade foot assembly extends towards one side of the concrete inner wall and blocks a lower opening of the containing cavity. According to the double-wall concrete open caisson structure, the concrete inner wall, the concrete outer wall and the concrete partition walls are used for forming a double-wall concrete open caisson, then after the double-wall open caisson sinks underground, the reinforcing anchor rods stretch into a soil layer, mortar is injected into the reinforcing anchor rods, the reinforcing anchor rods are tightly combined with a peripheral soil body, and tight connection between the double-wall open caisson and an external soil layer is improved.
本发明提供了一种双壁混凝土沉井结构及施工方法，涉及混凝土沉井技术领域，包括混凝土内壁、混凝土外壁、若干个混凝土隔墙以及若干个增强锚杆，混凝土外壁与混凝土内壁之间形成容纳腔；混凝土隔墙设置于容纳腔内；增强锚杆贯穿混凝土内壁和混凝土外壁设置，且沿混凝土外壁的径向向外延伸；其中，混凝土外壁的下端设有刃脚组件，刃脚组件向混凝土内壁一侧延伸，并封堵于容纳腔的下口处。本发明提供的双壁混凝土沉井结构，利用混凝土内壁、混凝土外壁和混凝土隔墙形成双壁混凝土沉井，再将上述双壁沉井沉入地下后，增强锚杆伸入土层内部，向增强锚杆内注入砂浆，使增强锚杆与外周土体严密结合，提高了双壁沉井与外部土层的紧密连接。
