Annular bridge tower top lifting construction method
The invention relates to an annular bridge tower top lifting construction method. The lifting construction method comprises the following specific steps: 1, erecting a lower annular section ground temporary buttress; 2, assembling a plurality of sections in the middle of a lower annular section; 3, connecting a temporary support to the lower annular section; 4, hoisting the pre-assembly part of an upper annular section; 5, sequentially jacking, continuously assembling the upper annular section and positively mounting the lower annular section on a cantilever; 6, closing the annular bridge tower, arranging an attached hydraulic jack at the end of the assembled lower annular section, and completing hoisting of the closed section of the annular bridge tower in cooperation with a crane. According to the method, the mode that the upper annular section is assembled on the riverbed ground and then jacked and assembled to the design position is adopted, splicing of the lower annular section and splicing of the upper half ring can be conducted synchronously, and the method has the advantages of being safe, economical and the like.
本发明是一种环形桥塔顶升施工方法，具体步骤如下：步骤一，架设下环段地面临时支墩；步骤二，拼装下环段中部多个截段；步骤三，下环段上接临时支撑；步骤四，吊装上环段预拼装部分；步骤五，依次顶升、续拼上环段以及悬臂正装下环段；步骤六，环形桥塔合拢，在拼装好的下环段端部设置附着式液压千斤顶，配合吊机完成环形桥塔合拢段的吊装。本发明方法中，上环段采用河床地面拼装再顶升续拼至设计位置的方式，下环段的拼装可与上半环的拼装同步进行，兼具安全、经济等多方面优势。
