Reinforcement cage for large-diameter variable cross-section pile foundation
The invention relates to a reinforcement cage for a large-diameter variable cross-section pile foundation, in particular to the technical field of bridge construction. The reinforcement cage comprisesan inner-layer reinforcement cage main body, an outer-layer reinforcement cage main body and a plurality of first stiffening rings, wherein the inner-layer reinforcement cage main body is provided with a reducing position matched with a variable cross-section position of the pile foundation, the reducing position divides the inner-layer reinforcement cage main body into a first unit and a secondunit which are sequentially arranged in the length direction of the inner-layer reinforcement cage main body, the outer-layer reinforcement cage body is arranged outside the first unit of the inner-layer reinforcement cage body in a sleeving mode, and a stiffening space is formed between the outer-layer reinforcement cage body and the first unit, all the first stiffening rings are located in the stiffening space and arranged at intervals in the axis direction of the first unit, the cross sections of the first stiffening rings are in an I shape, and the outer-layer reinforcement cage body is connected to the first unit of the inner-layer reinforcement cage body through the first stiffening rings. According to the reinforcement cage, cross-shaped or triangular supporting ribs do not need tobe additionally arranged on the first stiffening rings, so that circumferential deformation of the reinforcement cage is prevented.
本申请涉及一种用于大直径变截面桩基的钢筋笼，涉及桥梁施工技术领域，其包括内层钢筋笼主体、外层钢筋笼主体和多个第一加劲环，内层钢筋笼主体上设有与桩基的变截面的位置相适配的变径位置，变径位置将内层钢筋笼主体分隔成沿该内层钢筋笼主体长度方向依次布置的第一单元和第二单元；外层钢筋笼主体套设于内层钢筋笼主体的第一单元外，并与第一单元之间形成一加劲空间；所有的第一加劲环均位于加劲空间内，并沿第一单元的轴线方向间隔布置，且第一加劲环的横截面呈工字型，外层钢筋笼主体通过第一加劲环连接于内层钢筋笼主体的第一单元上。本申请的钢筋笼不需在第一加劲环上增设十字或三角形支撑筋，来防止钢筋笼的环向变形。
