Open caisson structure and open caisson construction method
The invention discloses an open caisson structure and an open caisson construction method, and belong to the technical field of buildings. The open caisson structure comprise an open caisson body, thelower part of the open caisson body is provided with a blade foot, and the open caisson structure is characterized in that the inner circumferential surface of the blade foot is an inclined surface,a plurality of supporting and pressing block bodies are uniformly distributed in the circumferential direction of the inner side of the open caisson body, the lower parts of the supporting and pressing block bodies are wedge-shaped surfaces, the upper parts of the supporting and pressing block bodies are bearing planes, and balancing weights are arranged on the bearing planes. The supporting and pressing block bodies can increase sinking resistance of the open caisson body, the balancing weights can provide extra sinking power, the increased resistance can effectively prevent the open caissonbody from suddenly sinking, and through weight adjustment of the balancing weights, the adjustable space of the sinking power is increased, so that the sinking controllability of an open caisson is improved, and sinking balance of the open caisson body is maintained.
本发明公开了一种沉井构造及沉井施工方法，属于建筑技术领域，包括沉井本体，沉井本体的下部为刃脚，其特征在于：所述刃脚内圆周面为斜面，所述沉井本体的内侧周向均布有若干支压块体，所述支压块体块的下部为楔形面，所述支压块体的上部为承托平面，所述承托平面上设置有配重块。支压块体可增大沉井本体的下沉阻力，配重块可提供额外的下沉动力，增加的阻力可有效放置沉井本体产生突沉现象，通过配重块的重量调节，增加了下沉动力的可调空间，从而提高沉井下沉的可控能力，且能够维持沉井本体的下沉平衡。
