Main bridge main span steel structure segment spare part type assembling method based on cantilever bridge girder erection machine
The invention discloses a main bridge main span steel structure segment spare part type assembling method based on a cantilever bridge erecting machine. Comprising the steps that a first main bridge main span steel structure section is hoisted, and a plurality of other main bridge main span steel structure sections which are sequentially spliced behind the first main bridge main span steel structure section are hoisted; the hoisting process of the first main bridge main span steel structure section comprises the following steps that 01, a cantilever bridge erecting machine is adopted for hoisting lower chords on the two sides of the first main bridge main span steel structure section, and the ends of the first main bridge main span steel structure section are temporarily fixed through stacking plates; 02, four adjusting web members of the first main bridge main span steel structure section are hoisted twice through a cantilever bridge erecting machine; 03, two upper chords of the first main bridge main span steel structure section are hoisted twice through a cantilever bridge erecting machine, and temporary steel pipes are adopted for supporting; and 04, an upper bridge deck, a decorative plate and a cantilever plate of the first main bridge main span steel structure section are sequentially hoisted through a cantilever bridge erecting machine.
本发明公开了一种基于悬臂架桥机的主桥主跨钢结构节段散件式拼装方法。包括首个主桥主跨钢结构节段的吊装以及若干个顺序拼接在首个主桥主跨钢结构节段后的其余主桥主跨钢结构节段吊装，其中：首个主桥主跨钢结构节段的吊装流程包括如下步骤：步骤01：采用悬臂架桥机吊装首个主桥主跨钢结构节段两侧的下弦杆，端部采用码板临时固定；步骤02：采用悬臂架桥机分两次吊装首个主桥主跨钢结构节段的四个调节腹杆；步骤03：采用悬臂架桥机分两次吊装首个主桥主跨钢结构节段的两个上弦杆，并采用临时钢管支承；步骤04：采用悬臂架桥机依次吊装首个主桥主跨钢结构节段的上桥面板、装饰板及挑臂板。
