Recyclable land wind power foundation prestress spiral anchor rod structure
The invention discloses a recyclable land wind power foundation prestress spiral anchor rod structure, and belongs to the technical field of wind power generation. The recyclable land wind power foundation prestress spiral anchor rod structure comprises a grouting channel and a spiral anchor rod; the grouting channel is located at the bottom of a concrete foundation and stretches into the foundation; a plurality of outer layer pipelines are arranged in the concrete foundation; inner layer pipelines are arranged in the outer layer pipelines; the spiral anchor rod penetrates the inner layer pipelines to extend into the grouting channel; a concrete pouring layer is arranged between the spiral anchor rod and the inner layer pipelines; the spiral anchor rod is of a hollow structure; grouting holes are formed in the side face of the spiral anchor rod; a plurality of spiral blades are arranged at the bottom of the spiral anchor rod and located in the grouting channel; and a self-breaking grouting layer is arranged between the grouting channel and the spiral anchor rod, and dismounting of the spiral anchor rod is achieved. By means of the anchor rod dismounting manner, the construction difficulty is greatly reduced.
本发明公开了一种可循环利用的陆上风电基础预应力螺旋锚杆结构，属于风力发电技术领域，包括灌浆通道和螺旋锚杆，所述灌浆通道位于混凝土基础底部，且灌浆通道伸入地基中，所述混凝土基础内设置有若干外层管道，所述外层管道内设置有内层管道，螺旋锚杆穿过内层管道延伸至灌浆通道内，所述螺旋锚杆与内层管道之间设置有混凝土浇筑层，所述螺旋锚杆为中空结构，所述螺旋锚杆侧面设置有灌浆孔，所述螺旋锚杆底部设置有若干螺旋叶片，所述螺旋叶片位于灌浆通道内，所述灌浆通道与螺旋锚杆之间设置有自破碎灌浆层，实现螺旋锚杆的拆卸，此种锚杆拆除方式大大降低了施工难度。
