Steel blade angle structure of vertical open caisson

Abstract

The steel blade angle structure of the vertical open caisson comprises an upper steel blade angle and a lower steel blade angle, the upper steel blade angle is defined by an upper top plate, an upper vertical plate, a first upper inclined lower plate and a second upper inclined lower plate, and the lower steel blade angle is defined by a lower inclined upper plate, a lower inclined lower plate, a lower bottom plate and a lower vertical plate; the second upper inclined lower plate and the lower inclined upper plate are connected through a fixing plate and form a steel strand channel allowing a steel strand to pass through, an arc-shaped guide plate is installed on the second upper inclined lower plate, a through hole is formed in the fixing plate, an anchor plate is fixed to the through hole of the fixing plate, a plurality of steel strand hole channels are formed in the anchor plate, and the steel strand channel is communicated with the arc-shaped guide plate. The ends, close to the through holes of the fixing plate, of the steel strand hole channels are circular holes, and the ends, away from the through holes of the fixing plate, are wedge-shaped holes. The steel blade angle structure has the advantages that one end of the steel strand passes through the steel strand channel formed by the upper steel blade angle and the lower steel blade angle and is anchored on the anchor plate in the steel blade angle structure, so that safe sinking of the vertical shaft can be ensured.
