Composite beam bridge and construction technology thereof
The invention provides a composite beam bridge and a construction process thereof, and relates to the technical field of bridge engineering. The composite beam bridge comprises a plurality of foundations, bridge piers and a main beam erected on the bridge piers, the main beam is a steel-concrete composite beam, and the composite beam is composed of a transverse full-width overall prefabricated prestressed concrete bridge deck slab and a stiffening rib-free steel beam. The construction technology comprises the steps that after construction of the bridge pier foundation is completed, the steel beam is constructed through a hoisting or pushing technology, then the prefabricated concrete bridge deck is hoisted, high-strength mortar between the bridge deck and the steel beam is poured, and then transverse wet joint pouring is conducted. The method is suitable for rapid prefabrication and assembly construction.
本发明提供了一种组合梁桥及其施工工艺，涉及桥梁工程技术领域。该组合梁桥包含：若干基础、桥墩，架设于桥墩上的主梁，主梁采用钢混凝土组合梁，组合梁由横向全宽整体预制预应力混凝土桥面板和无加劲肋钢梁组成。本施工工艺包括桥墩基础施工完毕后，先通过吊装或者顶推工艺实施钢梁，然后吊装预制混凝土桥面板，浇注桥面板与钢梁之间高强砂浆，再进行横向湿接缝浇注。本发明适用于快速预制拼装施工。
