Construction method for widening old bridge and bridge structure
The invention relates to a construction method for widening an old bridge and a bridge structure, and the construction method comprises the following steps: outwards extending and pouring an expanded inner side bearing platform in the bridge width direction on one side, which needs to be widened, of an old bridge bearing platform; on the old bridge tower columns, extending outwards in the bridge width direction to form expansion inner side tower columns in a pouring mode; according to the size specifications of the old bridge bearing platform and the old bridge tower column, an expansion outer side bearing platform and an expansion outer side tower column are poured on the outer side of the expansion inner side bearing platform; constructing an upper expansion cross beam and a lower expansion cross beam between the expansion inner side tower column and the expansion outer side tower column; and constructing and expanding the framing bridge on the lower expanding cross beam to finish the construction. The method has the beneficial effects that the expanding inner side bearing platform is poured in the mode that the old bridge bearing platform extends outwards in the bridge width direction, the expanding inner side tower column is poured in the mode that the old bridge tower column extends outwards in the bridge width direction, the width of the bearing platform and the width of the tower column between the expanded bridge and the old bridge are reduced, and the utilization rate between the new bridge and the old bridge is effectively increased.
本发明涉及一种旧桥拓宽的施工方法及桥梁结构，包括以下步骤：在旧桥承台需要拓宽的一侧，朝桥宽方向向外，延伸浇筑出拓展内侧承台；在旧桥塔柱上，朝桥宽方向向外，延伸浇筑出拓展内侧塔柱；按照旧桥承台及旧桥塔柱的尺寸规格，在拓展内侧承台的外侧浇筑拓展外侧承台及拓展外侧塔柱；在拓展内侧塔柱与拓展外侧塔柱之间施工上拓展横梁及下拓展横梁；在下拓展横梁上施工拓展分幅桥梁，即，完成施工。本发明的有益效果在于：通过在旧桥承台朝桥宽方向向外，延伸浇筑出拓展内侧承台，在旧桥塔柱朝桥宽方向向外延伸浇筑拓展内侧塔柱，使拓展的桥梁与旧桥之间的承台及塔柱的宽度减小，有效提高了新桥与旧桥之间的利用率。
