Bridge large-diameter precast concrete tubular column foundation and construction method thereof
The invention belongs to the technical field of bridge foundation construction, and particularly relates to a bridge large-diameter prefabricated concrete tubular column foundation and a construction method thereof. The upper end of the tubular column body is fixedly connected with a connecting section, a pier column and a cover beam in sequence; the pipe column body is formed by splicing a group of pipe joints end to end; a water guide hole is formed in the side surface of the pipe joint; a blocking groove is formed in the outer side of the water guide hole; a blocking piece is rotationally connected into the blocking groove; a net plate is fixedly connected to the interior of the water guide hole; and a connecting piece is fixedly connected between the screen plate and the plugging sheet. External water enters the pipe joint through the blocking groove and the water guide hole to supplement water to the interior of the pipe column body, the dredging efficiency of dredging equipment is improved, the water and rock soil excavated in the pipe column body form muddy water, outward suction is facilitated, the phenomenon of soil gushing or sand drifting is avoided, the water guide hole is formed, the effect of automatically supplementing water to the interior of the pipe column is achieved, and the service life of the pipe column is prolonged. The construction process is simplified, and the construction cost is reduced.
本发明属于桥梁基础施工技术领域，具体的说是一种桥梁大直径预制混凝土管柱基础及其施工方法，包括管柱体；所述管柱体上端依次固定连接有连接段、墩柱和盖梁；所述管柱体由一组管节首尾拼接组成；所述管节侧面开设有导水孔；所述导水孔外侧设置有封堵槽；所述封堵槽内部转动连接有封堵片；所述导水孔内部固定连接有网板；所述网板与封堵片之间固定连接有连接件。外界的水通过封堵槽和导水孔进入管节内部，为管柱体内部补充水，提高挖泥设备的挖泥效率，并与管柱体内部挖开的岩土形成泥水，便于向外抽吸，并避免发生涌土或流砂现象，通过设置导水孔，起到为管柱内部自动补水的作用，简化了施工流程，降低施工成本。
