Reinforcement reinforcement method and system for foundation anchor bolts of power transmission tower
The invention discloses a reinforcement reinforcement method and system for foundation anchor bolts of a power transmission tower. The reinforcement system comprises a concrete pile foundation, a plurality of anchor rods are arranged in the center of the concrete pile foundation in the axial direction, the anchor rods form an anchor bolt group, the reinforcement system further comprises a plurality of L-shaped steel bars, the L-shaped steel bars are annularly and evenly arranged with the anchor bolt group as the center, and the L-shaped steel bars are connected with the concrete pile foundation through the L-shaped steel bars. The L-shaped reinforcing steel bar comprises a reinforcing steel bar horizontal section and a reinforcing steel bar vertical section which are perpendicular to eachother, the reinforcing steel bar vertical section extends downwards to be inserted into a hole channel in the concrete pile foundation, the hole channel is filled with epoxy resin glue, the reinforcing steel bar vertical section extends downwards to exceed the fracture surface of the concrete cone by a certain length, and the exceeding part is the calculated anchoring length. The steel bar horizontal section extends outwards in the radial direction of the concrete pile foundation and has a certain anchoring length. The problem that an existing crack repairing method cannot fundamentally inhibit cracks is solved, and the method has the advantage of being simple in construction operation.
本发明公开了一种输电塔基础锚栓的置筋加固方法及系统，所述加固系统包括混凝土桩基，所述混凝土桩基的中心在轴向上设置有多个锚杆，多个锚杆构成锚栓群，还包括若干L形钢筋，若干L形钢筋以锚栓群为中心环向均匀布置，所述L形钢筋包括相互垂直的钢筋水平段和钢筋竖直段，钢筋竖直段的向下延伸插入混凝土桩基内的孔道内，所述孔道内填充有环氧树脂胶，所述钢筋竖直段向下延伸超过混凝土锥体破裂面一定长度，超出部分为计算锚固长度，所述钢筋水平段沿着混凝土桩基径向向外延伸，且具有一定锚固长度。本发明解决了现有修补裂缝的方法不能从根本上抑制裂缝的问题，且具有施工操作简单的优点。
