Construction method for erecting 40m box girder on paved 35m girder
The invention discloses a construction method for erecting a 40m box girder on a paved 35m girder, which comprises the following steps of: S1, establishing a 35m prefabricated box girder model by using finite element software for calculation and analysis to obtain a feasible conclusion; s2, a first crane and a second crane are arranged; s3, the first crane is hoisted to the left bridge floor of the xth span, and the second crane is located within the range of the (X + 2) th span; s4, the first crane and the second crane erect the 40m box girder from the girder transporting vehicle to an inner edge beam and an inner middle beam of the (x + 1) th span according to preset hoisting steps; s5, after the inner edge beams and the inner middle beams are erected, a beam transporting channel of the (x + 1) th span is formed; and S6, after remaining box girders on the left of the (x + 1) th span are completed through the beam transporting channel of the (x + 1) th span, the erected left of the (x + 1) th span serves as a beam transporting channel of the right of the (x + 1) th span, and hoisting of the right box girders of the (x + 1) th span is completed. Finite element software is used for building a 35m prefabricated box girder model for calculation and analysis, and a construction method for erecting 40m box girders on the laid 35m girders is provided accordingly.
本发明公开了已铺架35m梁上架设40m箱梁的施工方法，包括以下步骤：S1：利用有限元软件建立35m预制箱梁模型进行计算分析，得出可行结论；S2：设置第一吊车和第二吊车；S3：将第一吊车吊至第x跨左幅桥面上，第二吊车站位第X+2跨范围内；S4：第一吊车和第二吊车按照预设吊装步骤将40m箱梁从运梁车上架设至第x+1跨的内边梁处和内中梁处；S5：内边梁处和内中梁处完成架设后，形成第x+1跨的运梁通道；S6：通过第x+1跨的运梁通道完成第x+1跨左幅剩余箱梁后，已架好的第x+1跨左幅作为第x+1跨右幅的运梁通道，完成吊装第x+1跨右幅箱梁，本申请利用有限元软件建立35m预制箱梁模型进行计算分析，并以此提出已铺架35m梁上架设40m箱梁的施工方法。
