Construction method and system for roof reinforcement system conversion of immersed tube prefabrication
The invention discloses a construction method and system for roof reinforcement system conversion of immersed tube prefabrication. The construction method is characterized by comprising the followingsteps that 1, construction before demolding of an outer mold of a segment n is carried out; 2, roof system conversion construction of a segment (n+1) is carried out; and 3, mold closing construction of the segment (n+1) is carried out. According to the construction method and system, roof reinforcement is bound in advance through a reinforcement trolley, critical path work is reduced through system conversion, the construction time of a critical path is effectively shortened, and full-section construction of immersed tubes is guaranteed; and longitudinal main ribs of the adjacent segments areconnected in the whole length direction, the construction quality is effectively improved, and the immersed tube water seepage risk is reduced.
本发明公开了一种用于沉管预制顶板钢筋体系转换的施工方法及系统，其特征在于，包括以下步骤：步骤1、节段n外模脱模前施工；步骤2、节段n+1顶板体系转换施工；步骤3、节段n+1合模施工。本发明采用钢筋台车提前绑扎顶板钢筋，通过体系转换，减少了关键线路工作，有效缩短了关键线路施工时间，保证了沉管全断面施工且相邻节段纵向主筋通长连接，提高了施工质量，降低了沉管渗水风险。
