Deepwater bare rock stratum river channel steel trestle structure, construction method and pouring device
The invention provides a deepwater bare rock stratum river channel steel trestle structure, a construction method and a pouring device. The steel trestle structure comprises a steel pipe pile foundation, a bearing beam, a bailey beam and a bridge floor; the steel pipe pile foundation comprises pile position drill holes formed in a riverbed exposed rock stratum through a drilling machine, steel pipe piles fixed in the pile position drill holes and underwater concrete arranged in the steel pipe piles and between the steel pipe piles and the pile position drill holes, and a connecting system is arranged between every two sets of steel pipe piles arranged in the longitudinal bridge direction. Connecting systems are also arranged between the steel pipe piles arranged in the transverse bridge direction, bailey beam limiters are arranged at the bottoms of the bailey beams to fix the bailey beams above the steel pipe piles, and the bridge deck comprises transverse distribution beams evenly arranged above the bailey beams in the transverse bridge direction, longitudinal beams arranged above the transverse distribution beams in the longitudinal bridge direction and a bridge deck arranged above the longitudinal beams. According to the deepwater bare rock stratum river channel steel trestle structure, through the process of firstly forming holes, then constructing the steel trestle and finally pouring the underwater concrete, the construction period can be greatly prolonged, and meanwhile, the stability of the steel pipe pile foundation of the steel trestle is ensured.
本发明提供一种深水裸露岩层河道钢栈桥结构及施工方法及灌注装置，钢栈桥结构包括钢管桩基础、承重梁、贝雷梁、桥面，所述钢管桩基础包括通过钻机在河床裸露岩层上形成的桩位钻孔、固定在桩位钻孔内的钢管桩、置于钢管桩内及钢管桩和桩位钻孔之间的水下混凝土，沿纵桥向设置的钢管桩每两组之间设有连接系，横桥向设置的所述钢管桩之间也设有连接系，所述贝雷梁底部设有贝雷梁限位器将其固定在钢管桩上方，所述桥面包括横桥向均匀设置在贝雷梁上方的横向分配梁、纵桥向设置在横向分配梁上方的纵梁、设置在纵梁上方的桥面板。本发明通过先成孔再钢栈桥施工，最后水下混凝土灌注的工艺，可大大提高施工工期，同时确保了钢栈桥钢管桩基础的稳定性。
