Anti-floating construction method for equivalent diaphragm wall reinforcement cage under low clearance condition
The invention discloses a base reinforcement cage for an equivalent diaphragm wall, 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; reinforcing steel bar barbs which are arranged obliquely upwards are welded to the lower portions of the vertical main reinforcements, and the reinforcing steel bar barbs are distributed on the vertical main reinforcements of the reinforcing cage body in an inverted-V-shaped structure. The percussion drill and the underreaming drill are adopted for grooving construction, a trapezoidal underreaming main hole can be obtained, meanwhile, the construction efficiency is improved, and the grooving construction quality of the equivalent diaphragm wall is guaranteed; the bottom-expanded main hole and the steel reinforcement cage base with the steel bar barbs are adopted, efficient quick-setting cement is matched, and the steel reinforcement cage and the bottom-expanded part of the main hole form a whole, so that the stability of the steel reinforcement cage is improved, the construction quality of the equivalent diaphragm wall is guaranteed, and the phenomenon that the steel reinforcement cage floats during grouting construction of the equivalent diaphragm wall is prevented.
本发明公开了一种用于等效地连墙的基座钢筋笼，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；所述垂直主筋下部焊接有斜向上设置的钢筋倒刺，所述钢筋倒刺呈倒V字形结构分布在钢筋笼体的垂直主筋上。本申请采用冲击钻机与扩底钻机进行成槽施工，能够获得梯形的扩底主孔，同时提高施工效率，保证等效地连墙成槽施工质量；采用扩底主孔与带钢筋倒刺的钢筋笼基座，并配合高效速凝水泥，使钢筋笼与主孔扩底部分形成整体，从而提高钢筋笼的稳固性，保证了等效地连墙的施工质量，防止钢筋笼在等效地连墙灌浆施工时发生浮笼现象。
