Abstract

The invention discloses a manufacturing device and a manufacturing method for a large-diameter super-long pile double-layer reinforcement cage. The manufacturing method comprises the following steps that a stiffening hoop is manufactured according to the design size; outer-layer main reinforcements used for forming the sections of the reinforcement cage are positioned and arranged on the universal jig frame; the stiffening hoops are arranged on the inner sides of the positioned outer-layer main reinforcements and are welded and fixed to the positioned outer-layer main reinforcements; in the length direction of the reinforcement cage, the stiffening hoops are positioned through the universal jig frame, and the positions of the inner-layer main reinforcements are marked on the inner sides of the stiffening hoops; the inner-layer main reinforcements are sequentially welded to the stiffening hoops; the rest outer-layer main reinforcements used for forming the reinforcement cage sections are positioned and welded on the stiffening hoops; and the manufactured reinforcement cage sections are numbered and stored. By means of the universal jig frame, the mode that manufacturing is performed while positioning calibration is performed is adopted, the situation that when main reinforcements are connected in a penetrating mode in a multi-layer small-interval reinforcement combining structure form, the distance between the inner-layer main reinforcements and the outer-layer main reinforcements is too small, mutual interference is caused, and the construction efficiency is affected is avoided, and efficient manufacturing of the double-layer reinforcement cage is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a manufacturing device and a manufacturing method of a double-layer reinforcement cage for large-diameter and super-long piles. Background technique [0002] During the construction of bridges or high-rise buildings, foundation piling may be required according to needs. Usually, machine punching and ink drilling are used. After the hole depth meets the design requirements, the reinforcement cage is lowered into the pile hole, and then the conduit is inserted for concrete pouring. Concrete has high compressive strength but low tensile strength, so it is necessary to lower the reinforcement cage to play a tensile role, and to restrain the concrete of the pile body so that it can bear a certain axial tension. [0003] Most of the pile foundations adopt constant section design, and in large bridges, the application of variable section design is also more common. A certain...
