High-reinforcement-ratio round pile reinforcement cage sleeve cage and construction method thereof
The invention provides a high-reinforcement-ratio round pile reinforcement cage sleeve cage and a construction method of the high-reinforcement-ratio round pile reinforcement cage sleeve cage. According to the steel bar uniform-section replacement principle, a single steel reinforcement cage with the high reinforcement ratio is changed into two steel reinforcement cages including the inner cage and the outer cage, the length of the inner cage and the length of the outer cage are equal to the length of the originally-designed single steel reinforcement cage, the outer diameter of the inner cageis 60-150 millimeters smaller than that of the outer cage, and the outer cage is arranged outside the inner cage in a sleeving mode. The problems that an existing seam welder cannot process the high-reinforcement-ratio round pile reinforcement cage, only manual processing operation can be adopted, the quality cannot be easily guaranteed, the processing efficiency is low, the labor and the cost are high, and due to the fact that reinforcement cage main reinforcements are dense, the filling rate of concrete located outside the reinforcement cage is poor, and the pile forming quality cannot be easily guaranteed are solved. The invention belongs to the field of constructional engineering.
本发明提供一种高配筋率圆桩钢筋笼套笼及其施工方法，根据钢筋等截面替换原理，将高配筋率的单个钢筋笼改为内笼和外笼共两个钢筋笼，内笼和外笼的长度与原设计的单个钢筋笼长度相同，内笼的外径尺寸比外笼的外径尺寸小60‑150mm，外笼套设于内笼的外部。以解决现有滚焊机无法加工高配筋率圆桩钢筋笼，只能采用人工加工，质量难以保证，且加工效率低、人工及成本高，同时，钢筋笼主筋密集造成钢筋笼外混凝土填充率不佳，成桩质量也难以保证的问题。属于建筑工程领域。
