Pushing and sliding construction method for double-width steel truss girder
The invention discloses a pushing and sliding construction method for a double-width steel truss girder. The method comprises the steps that longitudinal moving temporary construction supports are arranged on the front side and the rear side of a pier set on the right side, and left-width temporary construction supports are arranged on the front side and the rear side of a pier set on the left side; a longitudinal moving slide way structure and a transverse moving slide way structure are erected on the longitudinal moving temporary construction support; a left first steel truss and a left guide beam are assembled on the longitudinal moving slide way structure, and a left second steel truss is assembled after the left first steel truss and the left guide beam are pushed forwards to a first preset position and is pushed forwards to a second preset position; the left truss girder is pushed to the left temporary construction support along the transverse sliding way structure and falls in place, so that the left truss girder is arranged on the first pier column and the second pier column in a spanning mode; a right first steel truss and a right guide beam are assembled on the longitudinal sliding way structure, and after the right first steel truss and the right guide beam are pushed forwards to a first preset position, a right second steel truss is assembled, and the right second steel truss is pushed forwards to a second preset position; and the right truss girder falls in place so that the right truss girder can be arranged on the third pier column and the fourth pier column in a spanning mode.
本发明公开一种双幅钢桁梁的顶推滑移施工方法包括：在右侧的墩组的前后侧设置纵移临时施工支架，在左侧的墩组的前后侧设置左幅临时施工支架；在纵移临时施工支架上搭设纵移滑道结构和横移滑道结构；在纵移滑道结构上拼装左幅第一钢桁架以及左幅引导梁，并向前顶推至第一预设位置后拼装左幅第二钢桁架，向前顶推至第二预设位置；将左幅桁架梁沿横移滑道结构顶推至左幅临时施工支架上并落梁就位，以使左幅桁架梁跨设于第一墩柱和第二墩柱；在纵移滑道结构上拼装右幅第一钢桁架和右幅引导梁，并向前顶推至第一预设位置后拼装右幅第二钢桁架，向前顶推至第二预设位置；将右幅桁架梁落梁就位，以使右幅桁架梁跨设于第三墩柱和第四墩柱。
