Prefabricated bridge non-landing horizontal rotation girder erection method
The invention relates to a prefabricated bridge non-landing horizontal rotating girder erection method, which comprises the following steps of: after construction of a prefabricated pile and a prefabricated cover beam is completed, erecting a next span of girder on an erected span of girder in a non-landing manner, and so on to complete all girder erection work, and comprises the following steps of: preparing before construction; the small box girder to be erected is transported to the site, one end of the small box girder to be erected is placed on the combined jack, the other end of the prefabricated small box girder is hoisted by the crawler crane, the small box girder is rotated by 180 degrees to the position above the next adjacent prefabricated cover beam with the combined jack as the center, the rubber support is installed, and the prefabricated small box girder is located on the rubber support; after one end of the prefabricated small box girder falls in place, the other end of the prefabricated small box girder is hoisted by the crawler crane, the combined jack is moved away, and the rubber support is installed, so that the prefabricated small box girder falls on the rubber support; and the combined jack is correspondingly moved on the prefabricated cover beam, so that a plurality of prefabricated small box beams in the to-be-erected one-span main beam can be conveniently hoisted. The ground environment is protected, and construction is convenient.
本发明是一种预制桥梁不落地平转架梁方法，预制桩和预制盖梁施工完成后，在已架设的一跨主梁上不落地架设下一跨主梁，以此类推完成所有架梁的工作，包括以下步骤：施工前准备；将待架设小箱梁运输到现场，一端放置于组合式千斤顶上，由履带吊吊起预制小箱梁另一端，以组合式千斤顶为中心，转动180°到下一个相邻的预制盖梁上方，安装橡胶支座，使预制小箱梁落位到橡胶支座上；预制小箱梁一端落位后，由履带吊吊起预制小箱梁另一端，移走组合式千斤顶，安装橡胶支座，使预制小箱梁落位到橡胶支座上；将组合式千斤顶在预制盖梁上进行相应移动，方便待架设一跨主梁内的多个预制小箱梁吊装。本发明保护了地面环境，施工方便。
