Steel blade angle structure for lifting and sinking open caisson
The invention discloses a steel blade angle structure for lifting and sinking an open caisson, which is arranged at the lowermost end of the open caisson and comprises a whole-section type steel blade angle and a sectional type lifting steel blade angle, and the whole-section type steel blade angle and the sectional type lifting steel blade angle are alternately arranged and combined to form a circle of steel blade angle structure; the sectional type lifting steel blade angle comprises an upper-section steel blade angle, a lower-section steel blade angle and a blade angle lifting plate connecting the upper-section steel blade angle and the lower-section steel blade angle, and the oblique lower side face of the upper-section steel blade angle and the oblique upper side face of the lower-section steel blade angle are arranged in parallel. The two ends of the blade angle lifting plate are perpendicularly welded to the oblique lower side face of the upper steel blade angle and the oblique upper side face of the lower steel blade angle respectively, and a plurality of steel strand holes are formed in the blade angle lifting plate at intervals. The steel blade foot has the advantages that the steel blade foot is adopted, self-compacting concrete is poured into the steel blade foot, and the overall rigidity of the blade foot is enhanced; a stiffening plate and a steel strand guide plate are arranged at a lifting point, so that the smooth force transmission of the structure is ensured; lifting points are evenly arranged around the open caisson, and the sinking speed and posture of the open caisson are controlled.
本发明公开了一种提吊下沉沉井的钢刃角结构，布置于沉井最下端，包括整段式钢刃角以及分段式提吊钢刃角，整段式钢刃角与分段式提吊钢刃角相互交替设置组合形成一圈钢刃角结构；其中，分段式提吊钢刃角包括上段钢刃角、下段钢刃角以及连接两者的刃角提吊板，上段钢刃角的斜向下侧面与下段钢刃角的斜向上侧面之间相互平行设置，刃角提吊板的两端分别垂直焊接于上段钢刃角的斜向下侧面上以及所述下段钢刃角的斜向上侧面上，刃角提吊板上间隔开设有若干钢绞线孔。本发明的优点是：采用钢刃脚，钢刃脚内灌注自密实混凝土，增强刃脚整体刚度；提吊点设置加劲板，钢绞线导板，确保结构传力顺畅；沿着沉井四周均匀设置提吊点，控制沉井下沉速度和姿态。
