Bridge widening structure and construction method
The invention discloses a bridge widening structure and a construction method, and relates to the technical field of bridge construction. The bridge widening structure comprises an old bridge; the new bridge pile foundation is poured on one side of the old bridge; the new bridge pier column is poured on the new bridge pile foundation; the temporary hoop is mounted between the new bridge pier column and the old bridge; the new bridge deck is poured on the new bridge pier columns, and the new bridge deck and the old bridge are arranged at intervals; the number of the first straining beams is multiple, the multiple first straining beams are installed on the new bridge pile foundation and the new bridge pier column correspondingly, and the multiple first straining beams are arranged at intervals; the second straining beams are arranged in one-to-one correspondence with the first straining beams; the post-cast sections are arranged between the bridge surface of the new bridge and the old bridge as well as between the first straining beam and the corresponding second straining beam, so that most shrinkage creep and settlement of the new bridge occur in the standing period through the cooperation of the temporary hoops, the first straining beam, the second straining beam and the post-cast sections; therefore, the probability of cracks near the junction surface of the new bridge and the old bridge is reduced.
本发明公开了一种桥梁加宽的构造及施工方法，涉及桥梁施工技术领域。该桥梁加宽的构造包括旧桥；新桥桩基，浇筑在旧桥的一侧；新桥墩柱，浇筑在新桥桩基上；临时抱箍，安装在新桥墩柱与旧桥之间；新桥桥面，浇筑在新桥墩柱上，且新桥桥面与旧桥间隔设置；第一系梁，第一系梁的数量为多个，多个第一系梁分别安装在新桥桩基以及新桥墩柱上，且多个第一系梁间隔设置；第二系梁，与第一系梁一一对应设置；后浇段，新桥桥面与旧桥以及第一系梁与对应的第二系梁之间均设有后浇段，这样，通过临时抱箍、第一系梁、第二系梁以及后浇段的配合，使得新桥的大部分收缩徐变和沉降发生在静置期期间，从而减小了新桥与旧桥的结合面附近出现裂缝的几率。
