Rigid cable-stayed bridge and incremental launching construction method
The rigid cable-stayed bridge comprises a rigid cable-stayed bridge framework formed by steel longitudinal beams (1), steel bridge towers (2), steel diagonal draw bars (3), steel secondary longitudinal beams (7) and steel cross beams (8), piers (5) are poured on the surface of a ground line (12) between roadbeds (11), supports (4) are arranged at the top ends of the piers (5), and bridge abutments (6) are arranged at the contact positions of the roadbeds (11) and the steel longitudinal beams (1); steel cross beams (8) are arranged between the steel longitudinal beams (1); secondary longitudinal beams (7) are arranged in the middle of the steel cross beams (8); opening profiled steel sheets (9) are arranged on the top surfaces of the steel cross beams (8) and the steel secondary longitudinal beams (7); and a concrete bridge deck (10) is poured on the opening profiled steel sheets (9). The construction method has the beneficial effects that rapid assembly can be achieved, pushing is conducted at the same time, bridge floor bottom construction can be closed, influences on underbridge navigation rivers and passing roads are limited, the construction period is short, the construction process is simple, and component stress is definite.
本发明一种刚性斜拉桥及顶推施工方法，包括钢纵梁(1)、钢桥塔(2)、钢斜拉杆(3)、钢次纵梁(7)、钢横梁(8)形成的刚性斜拉桥骨架，路基(11)之间地面线(12)表面浇筑桥墩(5)，桥墩(5)顶端设支座(4)，路基(11)与钢纵梁(1)接触处设桥台(6)；钢纵梁(1)之间设钢横梁(8)；钢横梁(8)中间设次纵梁(7)；钢横梁(8)与钢次纵梁(7)顶面设开口压型钢板(9)，在开口压型钢板(9)上浇筑有混凝土桥面板(10)。本发明有益效果：能够快速拼装、同时顶推、可封闭桥面底施工、对桥下通航河道和通行道路影响有限、施工周期短、施工过程简单、构件受力明确。
