Equivalent diaphragm wall reinforcement cage anti-floating correction structure and construction method
The invention discloses an equivalent diaphragm wall reinforcement cage anti-floating correction structure which is characterized in that a reinforcement cage body is formed by welding and combining vertical main reinforcements and annular main reinforcements, and the reinforcement cage body is of a cylindrical hollow structure; the steel reinforcement cage body is sleeved with steel base plates, and air bags are arranged between the steel base plates or between the steel base plates and a pit wall. The air bag is further communicated with an air pipe used for inflation or deflation. According to the construction method, lateral pressure is applied to the reinforcement cages through the air bags arranged between the reinforcement cages, the integrity of the reinforcement cages is improved, the positions of the reinforcement cages in the groove pits are fixed, it is avoided that the reinforcement cages are too long and thin to bend and deviate or float due to impact during concrete pouring, and the problems that the reinforcement cages float and deviate are effectively solved; and a secondary pouring procedure is adopted, after primary pouring concrete is condensed, the integrity and stability of the reinforcement cage are further improved, and the upward floating phenomenon of the reinforcement cage is weakened or even eliminated.
本发明公开了一种等效地连墙钢筋笼抗浮校正结构，所述钢筋笼体由垂直主筋和环形主筋焊接组合而成，所述钢筋笼体为圆柱形空心结构；所述钢筋笼本体上套设有钢垫板，所述钢垫板之间、或者钢垫板与坑壁之间设置有气囊；所述气囊还连通有用于充气、或放气的气管。本申请的施工方法通过在钢筋笼间设置的气囊对钢筋笼施加侧向压力，增加钢筋笼整体性、固定钢筋笼在槽坑中的位置，避免钢筋笼过于细长而发生弯斜偏移或者混凝土灌注时受冲击浮动，有效解决了钢筋笼浮动、偏移的问题；采用二次灌注工序，在初次灌注混凝土凝结后，钢筋笼的整体性和稳固性进一步提升，削弱甚至削出钢筋笼上浮现象。
