Construction method for prefabricating and assembling open caisson reinforcing steel bar sections
The invention belongs to the technical field of suspension bridge anchor open caisson steel bar installation and construction, and particularly provides an open caisson steel bar segment prefabricating and splicing construction method which comprises the steps that well wall steel bars and partition wall steel bars of an open caisson are subjected to segment division; steel bars are manufactured according to the divided sections; manufacturing a hoisting stiff framework of each section; manufacturing a reinforcing mesh of each section; the upper layer and the lower layer of the hoisting stiff framework of each section are connected with the steel bar meshes of the corresponding sections, and prefabrication of steel bars of each section is completed; moving each prefabricated section of reinforcing steel bar to the divided corresponding sections and mounting the reinforcing steel bars; mounting a protective layer cushion block on the mounted reinforcing steel bars to finish construction; the problems that under the existing construction conditions that the number, types and configurations of reinforcing steel bars are large, the conventional field reinforcing steel bar binding project amount is large, the effect is poor, and the work efficiency is low are solved. The construction method is small in work amount, high in practicability, reliable in safety performance and high in construction efficiency, and the open caisson steel bar segment construction technology is widened.
本发明属于悬索桥锚锭沉井钢筋安装施工技术领域，具体提供了一种沉井钢筋节段预制拼装的施工方法，将沉井的井壁钢筋和隔墙钢筋进行节段划分；根据划分后的节段制作钢筋；制作各节段的吊装劲性骨架；制作各节段的钢筋网片；在各节段的吊装劲性骨架的上层和下层均连接对应节段的钢筋网片，完成各节段钢筋的预制；将预制的各节段钢筋移动至划分的对应节段并安装；在安装后的钢筋上安装保护层垫块，完成施工；解决了现有在钢筋数量多、类型多、配置多的施工条件下，常规现场绑扎钢筋工程量大，效果差，工效低的施工组织缺陷问题。本发明工程量小，拓宽了沉井钢筋节段施工工艺，实用性强，安全性能可靠，施工效率高。
