Method for installing large special bailey beam
The invention provides a method for installing a large special bailey beam, and belongs to the technical field of bridge construction technologies. The method for installing the large special bailey beam comprises the following steps that S1, a temporary supporting cushion cross beam is installed on the top of each mid-span pile; s2, sequentially hoisting two special beret pieces for the second time; s3, one special beret piece is sequentially hoisted for the third time; s4, sequentially hoisting one, two and three follow-up specially-made beret pieces, switching to a tower crane on the other side for hoisting, and mutually fixing all the specially-made beret pieces; s5, beret pieces are used as longitudinal beams, a simple device capable of moving horizontally is arranged, and two 20 t chain blocks are hung to lift a cross beam; the cross beams are transported to designated positions by the floating platform, and gaps between the cross beams and the longitudinal beams are supported by steel plates; s6, the whole falling bailey beam falls onto the cross beam; and each group of bailey beams adopts a 32t screw jack, and a support pad is sequentially dropped and dismantled until the bailey beams fall to the top of the cross beam. According to the invention, the problem that no large-scale water equipment is used for hoisting overweight components is solved; and the hoisting safety risk is controllable.
本发明提供了一种大型特制贝雷梁安装的方法，属于桥梁施工技术技术领域。该一种大型特制贝雷梁安装的方法：包括如下步骤：S1：在每根中跨桩顶安装临时支垫横梁；S2：依次吊装第二次两片特制贝雷片；S3：依次吊装第三次一片特制贝雷片；S4：依次吊装后续1片、2片、3片特制贝雷片，转换另一侧塔吊吊装，全部相互固定；S5：利用贝雷片作为纵梁，设置简单可水平移动装置，悬挂两幅20t倒链提升横梁；横梁由浮式平台运输至指定位置，横梁与纵梁间间隙采用钢板支垫；S6：下落贝雷梁整体落至横梁上；每组贝雷梁采用32t螺旋千斤顶，依次落顶和拆除支垫，直至落至横梁顶上。本发明解决了无大型水上设备吊运超重构件的问题；吊装安全风险可控。
