The invention discloses a tower group construction method for alternate dislocation tower top lifting. The tower group construction method comprises the following steps that a building project is divided into a plurality of work areas; three tower cranes are arranged in each work area, the hoisting range of the three tower cranes completely covers the work area, the three tower cranes comprise a constant low tower, a translocation middle tower and a translocation high tower, and the initial fall of the three tower cranes is a preset height; the three tower cranes are jacked step by step according to multiple stages, in each jacking stage, the top of the translocation middle tower is lifted by at least two times of the preset height, the top of the constant low tower is lifted by one prefabricated height, and the translocation high tower is kept at the original height, so that the translocation middle tower is converted into the translocation high tower in the next stage, and the translocation high tower is converted into the translocation middle tower in the next stage; the constant-low tower is still the constant-low tower in the next stage. According to the method, the problems that partition construction is adopted for existing building engineering with the large volume, and building construction shutdown is likely to occur due to the fact that a group engineering cluster tower crane lifting scheme lacks unified deployment are solved.

    本发明公开了一种交替易位错塔顶升的群塔施工方法,包括以下步骤:将建筑工程划分为多个工区;于每个工区设置三台塔吊,三台塔吊的吊装范围全覆盖工区,三台塔吊包括一恒低塔、一易位中塔和一易位高塔,三台塔吊的初始落差分别为一预设高度;按多个阶段逐步顶升三台塔吊,在每个顶升阶段中,易位中塔顶升至少两倍预设高度,恒低塔顶升一预制高度,易位高塔维持原高度,使得易位中塔转变为下一个阶段的易位高塔,而易位高塔转变为下一个阶段的易位中塔,恒低塔仍然为下一个阶段的恒低塔。本发明解决了现有的体量较大的建筑工程采用分区施工,由于群体工程集群塔吊顶升方案缺乏统一部署易出现建筑施工停工的问题。
