Pipe barrel type wind tower foundation in soft soil area and construction method of pipe barrel type wind tower foundation
The invention relates to the technical field of wind tower foundations, in particular to a soft soil area pipe barrel type wind tower foundation and a construction method thereof.The wind tower foundation comprises an original circular-truncated-cone-shaped foundation, a new foundation and secant piles, a new top platform is poured at the top of the original circular-truncated-cone-shaped foundation, and the new foundation is arranged on the side surface of the original circular-truncated-cone-shaped foundation; first hidden beams are arranged on the periphery of the new top platform in the circumferential direction, reinforcing steel bars in the first hidden beams are connected with anchor bolt cage reinforcing steel bars in the original circular-truncated-cone-shaped foundation, new unit pre-stressed anchor bolts are arranged in the first hidden beams, and the new unit pre-stressed anchor bolts are anchored into the original circular-truncated-cone-shaped foundation. Second hidden beams are arranged outside the new foundation in the annular direction, and secant piles are arranged below the second hidden beams. Under the condition that the occupied area of an original foundation is not enlarged basically, the overall strength is improved, the bearing capacity of the original foundation is improved, and the engineering cost and the construction period are saved.
本发明涉及风塔基础技术领域，尤其是涉及一种软土区管筒型风塔基础及其建造方法，风塔基础包括原有圆台形基础、新基础及咬合桩，所述原有圆台形基础的顶部浇筑有新顶台，所述原有圆台形基础侧表面设有新基础，所述新顶台周边环向设有第一暗梁，所述第一暗梁内的钢筋与所述原有圆台形基础内的锚栓笼钢筋相连，所述第一暗梁内设有新机组预应力锚栓，所述新机组预应力锚栓锚入所述原有圆台形基础内。所述新基础外环向设有第二暗梁，第二暗梁下设置咬合桩。本发明在基本不扩大原有基础占地面积的情况下，增大了整体的强度，提升了原有基础的承载能力，节约了工程成本和工期。
