Construction method combining rotation and pushing of continuous rigid frame bridge girder
The invention discloses a construction method combining rotation and pushing of a main beam of a continuous rigid frame bridge. The construction method comprises the following steps that S1, a lower bearing platform is constructed; s2, spherical hinge construction; s3, constructing an upper bearing platform; s4, constructing a bracket; s5, bridge pier construction; s6, a main beam construction stage; s7, a rotation stage; s8, a pushing stage; s9, a splicing stage; s10, a closure stage; and S11, a bridge forming stage. Compared with the prior art, the method has the advantages that swivel construction and incremental launching construction are flexibly combined, and cross-railway construction of the continuous rigid frame bridge is innovated. The defects that a continuous rigid frame bridge cantilever casting method is long in construction period, large in risk, numerous in uncontrollable factors and the like and the limitation of incremental launching construction application are overcome. And the main beam can be quickly connected with a prefabricated section after rotating, so that the construction step of cast-in-place is reduced. The construction period is greatly shortened, the complexity of section-by-section construction and field unsafe factors are reduced, and meanwhile, complicated construction tools such as a hanging basket and the like can be replaced with a simpler jack, a simpler traction oil cylinder and the like.
本发明公开了连续刚构桥主梁转体与顶推相结合的施工方法，包括以下步骤：S1.下承台施工；S2.球铰施工；S3.上承台施工；S4.支架施工；S5.桥墩施工；S6.主梁施工阶段；S7.转体阶段；S8.顶推阶段；S9.拼接阶段；S10.合龙阶段；S11.成桥阶段。本发明与现有技术相比的优点在于：灵活地将转体施工与顶推施工相结合，对连续刚构桥跨铁路施工进行创新。弥补了连续刚构桥悬臂浇筑法施工工期长、风险大、不可控因素众多等缺陷以及顶推施工应用的局限性。可在主梁转体后迅速与预制段进行连接，减少现场浇筑的施工步骤。大量减少施工工期，减少逐段施工的复杂程度以及现场不安全因素，同时可将挂篮等复杂施工器具更换为更简易的千斤顶以及牵引油缸等。
