Self-pretension steel wire rope mesh reinforcing construction method
The self-pretension steel wire rope mesh reinforcing construction method comprises the steps that an anchorage device is made to be vertically attached to the outer vertical face of a pier through a temporary fixing device, and a plurality of steel wire ropes are sequentially arranged on the anchorage device in a penetrating mode around the pier from top to bottom; synchronously tensioning the plurality of steel wire ropes by utilizing a tensioning device, so that one end of each steel wire rope is clamped on one side of the anchorage device, and the other end of each steel wire rope penetrates out of the other side of the anchorage device and is automatically pre-tensioned; dedusting and cleaning the reinforced surface, pressing and smearing permeable polymer mortar, pressing and smearing the polymer mortar in layers, and watering and maintaining after the construction of the polymer mortar is completed. According to the reinforcing construction method, the body structure of the bridge pier cannot be secondarily damaged in the reinforcing process, the bridge pier does not need to be punched, secondary damage to a seriously damaged part is avoided, the load of the seriously damaged part is reduced, the seriously damaged part can be filled and restored by subsequently matching with coating of polymer mortar, and the construction efficiency is improved. And the pier restores the original structure for continuous use.
本发明公开一种自预张拉钢丝绳网片加固施工方法，通过临时固定装置使锚具竖向贴近所述桥墩的外立面，在锚具上从上至下围绕桥墩依次穿设若干钢丝绳；利用拉紧装置同步拉紧若干所述钢丝绳，使所述钢丝绳的一端卡紧在所述锚具的一侧、另一端从所述锚具另一侧穿出并自预张紧；对加固面进行除尘清理，压抹渗透性聚合物砂浆，聚合物砂浆分层压抹，完成聚合物砂浆施工后进行洒水养护。本加固施工方法在加固过程中不会二次破坏所述桥墩的本体结构，不用在桥墩上打孔，避免对严重损坏部位再次造成伤害，降低严重受损部位的负荷，后续再配合聚合物砂浆的涂覆，能够填补和复原严重受损部位，使桥墩恢复原有结构继续使用。
