Cantilever side span cast-in-place section bending moment balance structure and construction method thereof
The invention discloses a cantilever side span cast-in-place section bending moment balance structure and a construction method thereof, and belongs to the technical field of bridge construction. The structure comprises a side pier, a bridge abutment, an approach bridge box girder, a locking mechanism and a connecting mechanism, padstones are arranged at the tops of the side pier and the bridge abutment, the bottom of one end of the approach bridge box girder is connected with the padstone at the top of the side pier through a support, the bottom of the other end of the approach bridge box girder is connected with the padstone at the top of the bridge abutment through a support, and the locking mechanism is located on the upper side of the side pier. One end of the connecting mechanism is connected with the approach bridge box girder, and the other end of the connecting mechanism is connected with the top of the abutment. According to the side-span cast-in-place section concrete balance weight device, balance weight can be automatically carried out, the provided bending moment balance weight is increased along with the increase of the weight of side-span cast-in-place section concrete, linear and equal-bending-moment balance weight is achieved, the balance weight effect is good, the side-pier body structure and stress safety are effectively protected, and the construction technology is simplified.
本发明公开了一种悬臂边跨现浇段弯矩平衡结构及其施工方法，属于桥梁施工技术领域。该结构包括边墩、桥台、引桥箱梁、锁定机构和连接机构，所述边墩和桥台的顶部均设有垫石，所述引桥箱梁一端的底部通过支座与边墩顶部的垫石连接，另一端的底部通过支座与桥台顶部的垫石连接，所述锁定机构位于边墩的上侧，并约束固结边墩顶部的垫石和支座，所述连接机构的一端与引桥箱梁连接，另一端与桥台顶部连接。能够自行进行配重，其所提供的弯矩配重随边跨现浇段混凝土重量增大而增大，实现了线性、等弯矩平衡配重，配重效果好，有效保护了边墩墩身结构和受力安全，且简化了施工工艺。
