Construction method for quickly assembling and integrally hoisting large-span steel box girder
The invention discloses a construction method for quickly assembling and integrally hoisting a large-span steel box girder. The construction method comprises the following steps: step 1, erecting temporary struts on two sides of an existing expressway; 2, a crawler crane is built, and meanwhile, all the sections are spliced and welded on the existing elevated ramp to form a to-be-mounted beam section; thirdly, the to-be-installed beam section is hoisted through a crawler crane, and angle adjustment is conducted on the to-be-installed beam section through an adjusting mechanism; and 4, the to-be-installed beam section is guided through a guide mechanism till the to-be-installed beam section is lowered to the temporary supporting column. The construction method has the effects of shortening the overall construction period and improving the construction efficiency.
本发明公开了一种大跨度钢箱梁快速组装整体吊装施工方法,其包括如下步骤：步骤一：在既有高速公路的两侧搭设临时支柱；步骤二：搭建履带吊，并同时在既有高架匝道上完成对各节段进行拼装焊接形成待安装梁段；步骤三：采用履带吊将待安装梁段吊起，通过调整机构对待安装梁段进行角度调整；步骤四：通过导向机构对待安装梁段进行导向，直至下放至临时支柱上。本申请具有缩短整体的施工周期，提升施工效率的效果。
