The invention relates to the technical field of bridge construction, in particular to a tandem type hoisting method. The tandem type hoisting method comprises the following steps that 1, a plurality of pre-hoisting pieces are moved to a hoisting position from a prefabricating yard to be stacked; and 2, at least two stacked pre-hoisting pieces are connected to a hoisting mechanism in series through slings, and the slings on the lower pre-hoisting pieces penetrate through reserved grooves in the upper pre-hoisting pieces on the slings; and when the reserved grooves exist in the pre-hoisting pieces, the slings of the pre-hoisting pieces on the lower layer penetrate through the reserved grooves in the pre-hoisting pieces on the upper layer. The purpose of series hoisting of the multiple pre-hoisting pieces is achieved, and on the premise that the cost is controllable, operation is easy and the safety risk is small, hoisting of the pre-hoisting pieces can be rapidly and efficiently conducted.
本发明涉及桥梁施工技术领域,具体涉及一种串联式吊装方法,包括如下步骤:步骤一,若干预吊件由预制场转运至起吊位置进行层叠码放;步骤二,将至少两个层叠码放的预吊件通过吊索与起重机构进行串联连接,在下的预吊件上的吊索穿过其上方预吊件上的预留槽。当预吊件上存在预留槽的情况下,将下层预吊件的吊索穿过上层预吊件上预留槽,实现多个预吊件串联式吊装的目的,在成本可控、操作简单和安全风险小的前提下,能够快速高效的进行预吊件的吊装。
