Large-span construction trestle under sea area deepwater bare rock condition
The invention relates to the technical field of bridge construction, in particular to a large-span construction trestle under the sea area deepwater bare rock condition, which comprises four-column buttresses, bailey beams and pit caps, a plurality of four-column buttresses are equidistantly distributed between a bridge abutment and a cofferdam, each four-column buttress comprises four steel pipe piles, and the bottoms of the steel pipe piles extend into bare rock of a seabed surface; four pile planting holes corresponding to the steel pipe piles are formed in the position, corresponding to each four-column buttress, of the seabed face, the steel pipe piles are sleeved with pit caps corresponding to the pile planting holes in a covering and buckling mode, the lower edges of the pit caps are tightly attached to the seabed face to form a concrete forming space, and the concrete forming space is filled with concrete so that the pit caps, the steel pipe piles and the pile planting holes can be fixedly connected into a whole. Pile bottom concrete and the anchor form composite anchoring, the stability of the trestle under the action of ocean long-period wind power, surge force and water flow force is guaranteed, the concrete can be prevented from being impacted and damaged by water flow in the pouring process of the pit cap, a concrete block is formed in the pit cap along with pouring of the concrete, and the stability of the steel pipe pile is improved.
本发明涉及桥梁施工的技术领域，具体涉及一种海域深水裸岩条件下的大跨度施工栈桥，包括四柱支墩、贝雷梁和坑帽，多个四柱支墩在桥台和围堰之间等距分布，四柱支墩包括四个钢管桩，钢管桩的底部伸入海床面的裸岩中；在海床面对应每个四柱支墩点位均设置有四个对应钢管桩的栽桩孔，钢管桩外部套接罩扣有对应栽桩孔的坑帽，坑帽下沿贴紧海床面形成混凝土成型空间，在混凝土成型空间填充混凝土，以将坑帽、钢管桩和栽桩孔固结为一体。桩底混凝土与锚锭形成复合锚固，既保证栈桥在海洋长周期风力、浪涌力、水流力作用下的稳定，坑帽在浇注过程中可以避免水流冲击破坏混凝土，随着混凝土的浇注在坑帽内形成混凝土块，提高钢管桩的稳定性。
