Large-span construction trestle steel pipe pile composite anchoring method 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 steel pipe pile composite anchoring method under the sea area deepwater bare rock condition, which comprises the following steps: S1, carrying out seabed scanning through multiple beams, S2, erecting a piling platform between two positioning ships, the method comprises the following steps: step 1, arranging a pile driving platform, and arranging four steel pipe piles of the same four-column buttress on the pile driving platform, step 3, lowering an impact hammer to a seabed surface through the steel pipe piles, step 4, lowering the steel pipe piles into pile planting holes, lowering pit caps along the outer walls of the steel pipe piles, and enabling the lower surfaces of the pit caps to be tightly attached to the seabed surface; and S5, concrete is poured along inner holes of the steel pipe piles, pile planting holes are drilled with the steel pipe piles as guide pipes, so that the drilling precision of the pile planting holes is guaranteed, pit caps corresponding to the steel pipe piles are arranged on the pile driving platform, a protection cover is formed above the pile planting holes in the pouring process, and the concrete is prevented from being impacted and damaged by water flow. A concrete block is formed in the pit cap along with concrete pouring, 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大跨度施工栈桥钢管桩复合锚固方法，包括以下步骤：步骤S1，通过多波束进行海床扫测，步骤S2，在两个定位船之间搭设打桩平台，在打桩平台上设置同一四柱支墩的四个钢管桩，步骤S3，将冲击锤通过钢管桩下放至海床面，步骤S4，将钢管桩下放至栽桩孔内，沿钢管桩外壁下放坑帽，使坑帽下表面贴紧海床面；步骤S5，沿钢管桩内孔灌注混凝土，以钢管桩为导管进行栽桩孔打设，从而保证栽桩孔的打设精度，在打桩平台上设置对应钢管桩的坑帽，浇注过程中在栽桩孔上方形成保护罩，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。
