Reinforcing device and reinforcing method for preventing beam falling and overturning of in-service bridge
The invention discloses an in-service bridge anti-falling and anti-overturning reinforcing device and method, and relates to the field of bridge construction and in-service bridge reinforcing and repairing. The reinforcing device is used for reinforcing a bridge, the bridge comprises a beam body, a cover beam bridge platform and a bridge pier, the reinforcing device comprises a reinforcing anchor rod used for being embedded into the beam body, the cover beam bridge platform and the bridge pier at the same time, and an anchor rod anchoring assembly used for locking the reinforcing anchor rod from the two ends of the reinforcing anchor rod to enable the reinforcing anchor rod to generate pretension. Compared with a common anti-falling beam anti-overturning reinforcing device, the pre-pressure applied by the device can be adjusted according to the bridge condition, an original structure stress system under the normal use condition is not changed, and the obvious engineering advantages that the transverse bridge direction rigid body translation sliding of the beam body under the large deformation condition can be additionally limited and the like are achieved. The problem of potential safety hazards in existing bridge engineering is solved, the single-column pier beam bridge body is prevented from overturning, manpower and financial resources are saved, and value is created for the country and the society.
本申请公开了在役桥梁防落梁抗倾覆的加固装置及加固方法，涉及桥梁建造以及在役桥梁加固修复领域。该加固装置，用以对桥梁进行加固，桥梁包括梁体、盖梁桥台和桥墩，包括用以同时埋入梁体、盖梁桥台、桥墩的加固锚杆，以及从加固锚杆的二端部锁定加固锚杆以形成使加固锚杆产生预张力的锚杆锚固组件。相比与常见的防落梁抗倾覆加固装置，本装置施加的预压力可根据桥梁状况调整，不改变正常使用条件下原有结构受力体系，可额外限制大变形条件下梁体横桥向刚体平移滑动等显著的工程优势。本发明既解决了现有桥梁工程上的安全隐患问题，防止独柱墩梁桥梁体倾覆，同时节约了人力财力，为国家及社会创造价值。
