Soft soil layer offshore wind power rock-socketed single pile construction method based on double pile casing structure
The invention belongs to the field of offshore wind power engineering, and particularly relates to a soft soil layer offshore wind power rock-socketed single pile construction method based on a double-pile casing structure. The method comprises the following steps: driving an outer pile casing into a soil layer and abutting against a rock stratum; driving a middle pile casing of the auxiliary guide frame into the soil layer and abutting against the rock stratum, wherein the diameter of the middle pile casing is smaller than that of the outer pile casing, the middle pile casing is located in the outer pile casing, and the top of the middle pile casing is higher than the sea surface; inserting the inner pile casing into the middle pile casing and driving the same into the rock stratum; drilling a pile hole; putting a single pile into the drilled pile hole and putting the single pile to a designed height; and grouting and reinforcing the bottom and the outer side of the single pile. According to the method, the soil body is reinforced through the inner and outer double pile casings, so that the possibility of soil body damage and collapse in the drilling process is reduced.
本发明属于海上风电工程领域，具体涉及一种基于双护筒结构软土层海上风电嵌岩单桩施工方法，包括以下步骤：将外护筒打入土层并与岩层相抵；将辅助导向架的中间护筒打入土层并与岩层相抵，中间护筒的直径小于外护筒的直径，中间护筒位于外护筒内，且中间护筒的顶部高出海面；将内护筒插入中间护筒并打入岩层；钻桩孔；将单桩放入钻好的桩孔并放至设计高度；在单桩底部及外侧进行灌浆加固。本发明通过内外双护筒的方式进行土体的加固，降低了在钻孔过程中发生土体破坏塌方的可能。
