The invention belongs to the technical field of operation, transportation, aircrafts, aviation, universe navigation subclasses, ground facilities or aircraft carrier deck facility classification. Theinvention relates to a bridge, in particular to a lever balance type bridge. The bridge is characterized in that the middle section of the bridge is not provided with bridge piers, supporting bridge piers are built at the proper positions of the two banks respectively to serve as balance supporting points of the bridge, then gravity piers are built at the backer ends of the supporting bridge piersrespectively, and then bridge box girder hoisting and splicing construction is conducted at the ends close to rivers (valleys); the moment of force of the gravity pier supporting one side of the bridge pier must be guaranteed to be always larger than the moment of force of the unilateral bridge supporting the other side of the bridge pier, so that the unilateral bridge can be guaranteed to be always kept in a relatively balanced and stable state. Connection between the box girders and the connection between the box girders and the gravity pier are finally conducted through steel column tenonsand reinforced concrete egg holes. And after the two unilateral bridges are completed, the middles of the bridges are fixedly connected.
本发明的技术领域属于作业、运输大类，飞行器、航空、宇宙航行小类，地面设施或航空母舰甲板设施分类。本发明涉及一种桥梁，特别是涉及一种杠杆平衡式桥梁。本发明的特征就是桥梁的中段没有桥墩，而是分别在两岸合适的位置建造支撑桥墩作为桥梁的平衡支撑点，再分别在支撑桥墩的靠山端建造完成重力墩，然后再分别在靠河(山谷)端进行桥梁箱梁的吊装拼接施工，当然，必须保证支撑桥墩一侧的重力墩的力矩始终大于另一侧单边桥梁的力矩，才能确保单边桥梁始终保持相对平衡稳定的状态，最后再通过钢柱榫和钢筋砼卵孔来进行各箱梁及箱梁与重力墩之间的连接，待到两单边桥梁完成后再进行桥梁中间的固定连接即可。
