Rock-socketed construction technology for large-diameter steel pipe inclined pile of offshore wind power high-rise pile cap foundation
The invention discloses a rock-socketed construction technology for a large-diameter steel pipe inclined pile of an offshore wind power high-rise pile cap foundation. The technology comprises the following processes of steel pipe pile sinking, platform bearing frame installation, rock-socketed construction platform installation, rock-socketed equipment installation, steel pipe pile rock-socketed construction and rock-socketed construction platform removal. When the platform bearing frame installation process is performed, a platform bearing frame adopts an H-type steel structure or a cap bottom sealing reinforced concrete structure; when the rock-socketed equipment installation process is performed, a drilling machine and an 80 t crawler crane are arranged on a rock-socketed construction platform, and auxiliary facilities including a container, a generator, a slag collecting box and an air compressor and living facilities are arranged; and the steel pipe pile rock-socketed constructionprocess comprises the following steps of hole drilling protection wall slurry mixture ratio test, hole forming, hole cleaning, steel reinforcement cage hoisting, guide pipe lowering installation andconcrete pouring. The rock-socketed construction technology has the advantages that the standardized construction degree is high, the construction safety is well guaranteed, and the construction progress can be greatly improved.
本发明公开了一种海上风电高桩承台基础大直径钢管斜桩的嵌岩施工工艺，包括以下流程：钢管桩沉桩、平台承重架安装、嵌岩施工平台安装、嵌岩设备安装、钢管桩嵌岩施工和嵌岩施工平台拆除。进行平台承重架安装流程时，平台承重架采用H型钢结构或采用承台封底钢筋混凝土结构；进行嵌岩设备安装流程时，在嵌岩施工平台上布置一台钻机和一部80t履带吊机，并配置包括集装箱、发电机、集渣箱、空压机的辅助设施以及生活设施；进行钢管桩嵌岩施工流程时，包括以下步骤：钻孔护壁泥浆配合比试验、成孔、清孔、钢筋笼吊装、导管下放安装和混凝土灌注。本发明的嵌岩施工工艺，标准化施工程度高，且对施工安全有较大的保障，能大幅度提高施工进度。
