Underwater steel pipe pile construction method for embedding steel pipe concrete into mid-weathered rock
The invention discloses an underwater steel pipe pile construction method for embedding a steel pipe concrete into mid-weathered rock, and relates to the technical field of steel pipe pile construction. S2, hole guiding and downward moving of the steel casing are conducted, a drilling machine is used for hole guiding in the steel casing on the piling platform, and the steel casing is moved downwards while hole guiding is conducted; s3, hole forming is conducted, specifically, after the steel casing is stabilized, the drilling machine is used for continuously drilling till the designed rock entering depth is reached through drilling; s4, lowering the steel pipe pile; s5, concrete is poured underwater; the piling platform comprises a fixed piling platform body and a floating piling platform body, the fixed piling platform body is used for constructing a steel pipe pile arrangement concentration area, the floating piling platform body is used for constructing a steel pipe pile arrangement dispersion area, and the floating piling platform body can also be used for assisting installation of the fixed piling platform body, so that the overall construction cost is greatly reduced, and the construction efficiency is improved.
本发明公开了一种钢管混凝土嵌入中风化岩的水中钢管桩施工方法，涉及钢管桩施工技术领域，包括如下步骤：S1：插打钢护筒；S2：引孔下移钢护筒，在打桩平台上使用钻机于钢护筒内引孔，边引孔边下移钢护筒；S3：成孔，待钢护筒稳定后，再使用钻机继续钻孔，直至钻到设计入岩深度；S4：下放钢管桩；S5：水下灌注混凝土；打桩平台包括固定打桩平台以及浮式打桩平台，固定打桩平台用于施工钢管桩布置集中区域，浮式打桩平台用于施工钢管桩布置分散区域，且浮式打桩平台也可用于辅助固定打桩平台安装，大大降低了整体施工费用，提高施工效率。
