Deepwater large-tonnage temporary pier foundation and construction method thereof
The invention discloses a deepwater large-tonnage temporary pier foundation and a construction method thereof, and relates to the technical field of temporary pier foundation construction. The construction method comprises the following steps that S1, a steel casing is constructed, the lower end of the steel casing penetrates through a riverbed, and the upper end of the steel casing is exposed out of the construction water level; S2, a drilled pile is constructed in the steel casing; and S3, water in the steel casing is extracted to form a water-free environment, the steel pipe pile is lowered into the steel casing, the steel pipe pile is connected with the drilled pile, and concrete is poured at the connecting structure. According to the construction method, the water-free environment is manufactured through the steel casing, the steel pipe pile and the drilled pile are connected in the water-free environment, and concrete is poured at the connecting structure, so that the steel pipe pile and the drilled pile are reliably connected, large-tonnage vertical load can be borne, and large shearing force and bending moment can be effectively borne.
本发明公开了一种深水大吨位临时墩基础及其施工方法，涉及临时墩基础施工技术领域，该施工方法包括以下步骤：步骤S1，施工钢护筒，并使钢护筒下端穿过河床、上端露出施工水位；步骤S2，在钢护筒内施工钻孔桩；步骤S3，抽取钢护筒内的水形成无水环境，下放钢管桩至钢护筒内，将钢管桩与钻孔桩连接，并在连接结构处浇筑混凝土。本发明通过钢护筒制造无水环境，在无水环境下将钢管桩与钻孔桩连接，并在连接结构处浇筑混凝土，使钢管桩与钻孔桩形成可靠的连接，不仅能承受大吨位竖向荷载，还能有效地承受较大的剪力和弯矩。
