Construction method for secondary conversion lowering of pile foundation reinforcement cage
The invention discloses a construction method for secondary conversion lowering of a pile foundation reinforcement cage, which is characterized in that the reinforcement cage is gradually lowered by arranging lengthened steel wire ropes in batches. The traditional concept that the reinforcement cage can only be lowered in place at one time is broken through, the defect that the reinforcement cage can be lowered for multiple times to meet the requirement for high lowering height and insufficient hoisting height through the improved construction method is overcome, meanwhile, the construction method can be completed through conventional equipment, large hoisting equipment does not need to be replaced, and the construction cost is reduced. Compared with the cost brought by the replacement of hoisting equipment, the added materials such as the secondary section steel wire rope and the hanging plate hook greatly reduce the project investment, meanwhile, the lowering of the reinforcement cage is realized by adopting the simplest process, the working efficiency and the construction quality are improved, the construction is safe and reliable, and the characteristics of strong applicability, strong economical efficiency, simplicity in operation and the like are realized.
本发明公开了一种桩基钢筋笼二次转换下放的施工方法，通过分次设置加长钢丝绳，完成钢筋笼的逐步下放。本发明打破了钢筋笼只能一次下放到位的传统观念，改进后的施工方法使钢筋笼可以多次下放以满足下放高度较高而吊高不足的缺点，同时，此施工方法采用常规设备即可完成，无需更换大型起吊设备，增加的次节钢丝绳、悬挂板钩等材料相比起吊设备更换带来的费用，大大减少了项目投入，同时也采用最简单的工艺实现钢筋笼的下放，提高了工作效率和施工质量，施工安全可靠，具有适用性强、经济性强、操作简单等特点。
