Secondary pouring construction method for double-wall steel cofferdam
The invention relates to a secondary pouring construction method for a double-wall steel cofferdam. The secondary pouring construction method comprises the steps that a hoisting platform is built at the position of a pier; the first double-wall steel cofferdam is hoisted to a hoisting platform, and a first blade foot is welded to the first double-wall steel cofferdam; the first double-wall steel cofferdam is lowered, and the second double-wall steel cofferdam is welded to the first double-wall steel cofferdam; the two sections of double-wall steel cofferdams are lowered to a riverbed; water in the double-wall steel cofferdam is discharged, and a hoisting platform is built at the position of the next pier; after construction of the pier is completed, the double-wall steel cofferdam is cut, the second blade foot is welded to the bottom of the second double-wall steel cofferdam, and the second double-wall steel cofferdam is put down; the first double-wall steel cofferdam is divided into a pouring part and an inserting part, and the pouring part is welded to the second double-wall steel cofferdam; the pouring part and the second double-wall steel cofferdam are lowered to a riverbed; and the steps are repeated, and water-free environment construction is conducted on the other bridge pier positions. The double-wall steel cofferdam has the advantages that the number of the double-wall steel cofferdams needing to be used is reduced, and the bridge fabrication cost is reduced.
本申请涉及一种双壁钢围堰二次倒用施工方法，其包括：在桥墩位置处搭建吊装平台；将第一双壁钢围堰吊运至吊装平台，对第一双壁钢围堰焊接第一刃脚；将第一双壁钢围堰下放，将第二双壁钢围堰焊接于第一双壁钢围堰；将两节双壁钢围堰下放至河床；将双壁钢围堰内的水排出，并在下一桥墩位置处搭建吊装平台；当完成该桥墩的施工后，对双壁钢围堰进行切割，将第二刃脚焊接于第二双壁钢围堰底部，将第二双壁钢围堰下放；将第一双壁钢围堰分割为倒用部和插入部，将倒用部与第二双壁钢围堰焊接；将倒用部和第二双壁钢围堰下放至河床；重复以上步骤，在其余桥墩位置进行无水环境施工。本申请具有减少需要使用的双壁钢围堰数量，降低造桥成本的效果。
