Single-column pier reinforcing structure capable of improving anti-overturning capacity of bridge
The invention relates to a single-column pier reinforcing structure capable of improving the anti-overturning capacity of a bridge. The single-column pier reinforcing structure comprises a lower fastening ring, an upper fastening ring, a pair of inclined struts, a pair of horizontal supporting platforms, vertical supporting columns and supports, wherein the lower fastening ring and the upper fastening ring are arranged on a pier column up and down in a sleeving mode respectively; the inclined struts are symmetrically arranged on the two sides of the pier column; the horizontal supporting platforms are arranged at the tops of the two inclined struts respectively; the vertical support columns are arranged on the horizontal support platforms and the supports are arranged on the tops of the vertical support columns. the bottoms of the inclined struts are connected with the lower fastening ring, and a horizontal inhaul cable matched with the upper fastening ring is arranged between the twohorizontal supporting platforms. Compared with the prior art, the structure is formed through fasteners and fixed to the pier column through the fastening rings, the bending moment borne by the pier when a beam body bears transverse eccentric loads can be reduced, and the beam body is prevented from overturning. Compared with a traditional reinforcing structure, the reinforcing structure is simplein structure, reliable in performance and clear in stress, and the stress performance of materials is fully utilized. In addition, the structure is small in occupied area and wider in application range.
本发明涉及一种提高桥梁抗倾覆能力的独柱墩加固结构，包括一下一上分别套设在墩柱上的下紧固环及上紧固环、一对对称设置在墩柱两侧的斜撑、一对分别设置在两个斜撑顶部的水平支撑平台、设置在水平支撑平台上的竖向支撑柱以及设置在竖向支撑柱顶部的支座，斜撑的底部与下紧固环相连，两个水平支撑平台之间设有与上紧固环相适配的水平拉索。与现有技术相比，本发明通过紧固件形成结构，并通过紧固环固定于墩柱上，可减少梁体受横向偏心荷载时桥墩所受弯矩，防止梁体发生倾覆。相比于传统加固结构，本发明结构构造简单且性能可靠，受力明确，充分利用材料受力性能。此外，本发明结构占地面积小，适用情况更为广阔。
