Bridge multi-point dispersion external prestress prefabricated module reinforcing device and reinforcing method thereof
The invention provides a bridge multi-point dispersion external prestress prefabricated module reinforcing device and a reinforcing method thereof. The device comprises a prefabricated steering piecearranged at a steering point of a to-be-reinforced bridge, a plurality of prefabricated anchoring parts, a wet joint, and a plurality of dispersive external prestressed cables, wherein a plurality ofdispersed anchoring points are arranged on the two opposite sides of the steering point; the plurality of prefabricated anchoring parts are arranged at the anchoring points; the wet joint is formed between the prefabricated anchoring part and the to-be-reinforced bridge, the wet joint is formed between the prefabricated steering piece and the to-be-reinforced bridge, and concrete is poured into the wet joint; and the plurality of dispersive external prestressed cables are arranged on the prefabricated steering piece in a penetrating manner, and the two ends of each dispersive external prestressed cable are connected to the prefabricated anchoring parts on the two opposite sides of the steering point respectively. Problems that according to a traditional bridge external prestress reinforcing method, external prestress is concentrated at an anchoring point or a steering point, construction is complex, and a construction period is long are solved.
本发明提供了一种桥梁多点分散体外预应力预制模块加固装置及其加固方法，该装置包括：预制转向件，所述预制转向件设置于待加固桥梁的转向点，所述转向点的相对两侧设置有分散的多个锚固点；多个预制锚固件，所述预制锚固件设置于所述锚固点；湿接缝，所述预制锚固件、所述预制转向件分别与所述待加固桥梁之间形成所述湿接缝，所述湿接缝中浇筑有混凝土；多个分散体外预应力索，所述分散体外预应力索穿设于所述预制转向件，所述分散体外预应力索的两端分别连接于所述转向点的相对两侧的所述预制锚固件。本发明解决了传统桥梁体外预应力加固方法存在体外预应力在锚固点或转向点较为集中，施工复杂、施工周期长的问题。
