T-beam bridge widening structure and construction method
The invention relates to the technical field of bridge reconstruction and extension construction, and discloses a T-beam bridge widening structure and a construction method. The T-beam bridge wideningstructure comprises a cross beam and a bridge floor connecting structure, the cross beam is connected with a T-beam web of a new bridge and a T-beam web of an old bridge, and the bridge floor connecting structure is connected with a T-beam bridge floor of the new bridge and a T-beam bridge floor of the old bridge. According to the T-beam bridge widening structure and the construction method provided by the embodiment of the invention, the lower structures of new and old bridges do not influence each other, the construction is effectively simplified, and the construction requirement of not interrupting the traffic of the old bridges under the condition of large traffic volume is met; the connection of the upper part comprises a bridge surface connecting structure for connecting the T-beambridge surfaces of the new bridge and the old bridge; and cross beams are arranged between the T-shaped beam webs of the new bridge and the old bridge, so that bridge longitudinal joints caused by differential settlement of the new bridge and the old bridge are avoided while dead load increase of the old bridge is effectively controlled to reduce adverse effects on the structure, the structure islight and handy, and construction and maintenance are convenient.
本发明涉及桥梁改扩建施工技术领域，公开了一种T梁桥拼宽构造及施工方法，拼宽构造包括横梁和桥面连接结构，横梁连接新桥的T梁腹板和旧桥的T梁腹板，桥面连接结构连接新桥的T梁桥面和旧桥的T梁桥面。本发明实施例提供的T梁桥拼宽构造及施工方法，新旧桥梁下部结构互不影响，有效简化了施工，满足大交通量情况下不中断旧桥交通的施工需求；上部的连接不但包括使新桥、旧桥T梁桥面相连接的桥面连接结构，还在新桥、旧桥的T梁腹板之间设置横梁，从而能够在有效控制旧桥恒载增加以减小对结构不利影响的同时，避免因新旧桥不均匀沉降所导致的桥梁纵缝，结构轻巧、施工方便、维护方便。
