Wind power single pile, pile sinking construction device and pile sinking construction method
According to the wind power single pile and pile sinking construction device and method, two crossed partition plates are arranged in the root section of a single pile body, and the partition plates are used for extruding filler entering the bottom of the pile; a barb is arranged on the outer wall of the root section of the single pile body, the barb is in a V shape and attached to the outer wall of the pile, the upper end of the V shape is closed and free of an opening, and the tip end faces the sinking direction of the wind power single pile. According to the pile sinking construction device, a second-stage pile casing is arranged in a first-stage pile casing, the second-stage pile casing is used for being placed into drilling equipment to excavate and drill a gravel layer, the second-stage pile casing integrally moves downwards along with the drilling equipment, and the second-stage pile casing drives the first-stage pile casing to sink; according to the pile sinking construction method, in the hole forming process section in single pile construction, a gravel layer is arranged below a rock stratum, a secondary pile casing is arranged in a primary pile casing, the secondary pile casing is used for being placed in drilling equipment to drill a hole in the gravel layer, and the primary pile casing and the secondary pile casing advance along with the drilling operation depth.
一种风电单桩和沉桩施工装置及施工方法，单桩本体根部段的内部设置有两个交叉的隔板，隔板用于挤压进入桩底部的填充物；单桩本体根部段的外壁设置有倒刺，倒刺为V型且贴合在桩的外壁，V型的上端封闭无开口设置，且尖端朝向风电单桩的下沉方向；沉桩施工装置，一级护筒内设置有二级护筒，二级护筒用于置入钻孔设备对碎石层开挖钻孔，且二级护筒随钻孔设备一体向下作业行进，二级护筒带动一级护筒下沉；沉桩施工方法，单桩施工中在成孔工艺段，岩层下方有碎石层，在一级护筒内设置二级护筒，二级护筒用于置入钻孔设备对碎石层钻孔，一级护筒和二级护筒随钻孔作业深度前进。
