The system safety problem of single-column pier bridges is prominent. Content of the Utility Model
[0004] In order to solve the above technical problems, the utility model proposes a reconstruction structure for a single-column pier bridge pier. When strengthening and rectifying the highest single-column pier body, two arc-shaped steel plates are installed on the outer side of the single-column pier body and fixed by bolts. That is, a steel hooping column cap beam is arranged at the contact top of the single-column pier body and the beam slab to increase the contact area with the beam slab, so that the force of the upper structure is more evenly transmitted to the bridge pier and the bridge pier foundation, further ensuring the safe and unobstructed operation of the highway bridge and ensuring the safe travel of the people. The steel hooping type cap beam reconstruction measure is faster in construction speed than adding supporting columns on both sides of the original independent bridge pier, greatly saves the construction period, has less impact on traffic, low cost, good aesthetics and good reconstruction effect.
[0005] The technical solution for achieving the purpose of the utility model is: a reconstruction structure for a single-column pier bridge pier, including a single-column pier body, on the circumferential outer side wall of the single-column pier body, two arc-shaped steel plates are fitted, and supports are fixedly connected to the outer side walls of the two arc-shaped steel plates. It also includes;
[0006] A stabilizing mechanism, which is located on the single-column pier body;
[0007] The stabilizing mechanism includes a plurality of fixing holes formed in the two arc-shaped steel plates, a plurality of connecting holes are formed in the single-column pier body, and a reinforcing bar body is fixedly connected in the plurality of fixing holes and the plurality of connecting holes together. Two fixing plates are fixedly connected to the two arc-shaped steel plates respectively, and every two fixing plates are fixedly connected by a plurality of bolts.
[0008] In some embodiments, cushion stones are fixedly connected to the tops of the two supports.
[0009] In some embodiments, support beams are installed on the outer side walls of the two arc-shaped steel plates, and a plurality of stiffeners are installed on both sides of the two support beams.
[0010] In some embodiments, the two cushion stones are both in an "I" shape.
[0011] Compared with the prior art, the utility model has the remarkable advantages that:
[0012] The utility model discloses when reinforcing and governing the highest single column pier body, installs two arc steel sheets outside single column pier body, fixes it through bolt, makes the force of upper structure more balanced transmission to bridge pier and bridge pier foundation through setting up steel hoop bent cap beam expansion and the contact area of beam board, further guarantees the safe and smooth of highway bridge, ensures the safe travel of the people, and the bent cap beam reconstruction measure of steel hoop is relative to the increase of the support column at the both sides of the original independent bridge pier, and the construction speed is fast, greatly saves the construction period, and the influence to traffic is less, and the cost is low, and the appearance is beautiful, and the reconstruction effect is good.
[0013] The system safety problem of the single column pier bridge is solved. BRIEF DESCRIPTION OF DRAWINGS

[0019] The utility model will be explained further in combination with the drawings and the embodiment:
[0020] The utility model discloses a kind of single column pier bridge pier reconstruction structures by improvement, and the technical scheme of the utility model is:
[0021] As Figures 1-2As shown, a single-column pier modification structure includes a single-column pier body 4. Two arc-shaped steel plates 2 are attached to the outer circumference of the single-column pier body 4. Supports 1 are fixedly connected to the outer walls of the two arc-shaped steel plates 2. The structure also includes a stabilizing mechanism located on the single-column pier body 4. The stabilizing mechanism includes multiple fixing holes 5 opened on the two arc-shaped steel plates 2. Multiple connecting holes are opened on the single-column pier body 4. Reinforcing steel bodies 6 are fixedly connected to the multiple fixing holes 5 and the multiple connecting holes respectively. Two fixing plates 7 are fixedly connected to the two arc-shaped steel plates 2 respectively. Each pair of fixing plates 7 is fixedly connected by multiple bolts 8. The stabilizing mechanism improves the stability of the single-column pier body 4.
[0022] like Figure 1 As shown, in one embodiment, the tops of both supports 1 are fixedly connected with pad stones 3; the pad stones 3 facilitate the support of the bridge.
[0023] like Figure 2 As shown, in one embodiment, support beams 9 are installed on the outer walls of both arc-shaped steel plates 2, and multiple stiffening ribs 10 are installed on both sides of the two support beams 9; the stiffening ribs 10 are provided to facilitate the enhancement of the structural stability of the support beams 9.
[0024] like Figure 1 As shown, in one embodiment, both pad stones 3 are in the shape of an "I"; the "I" shape facilitates the support of the bridge and the support 1.
[0025] The specific working method is as follows: When the highest single-column pier body 4 needs to be reinforced and renovated, two arc-shaped steel plates 2 are installed on the outside of the single-column pier body 4 and fixed with bolts 8. That is, the contact area between the single-column pier body 4 and the beam is expanded by setting steel clamp cap beams at the top of the contact between the single-column pier body 4 and the beam, so that the force of the superstructure is more evenly transmitted to the pier and the pier foundation, further ensuring the safety and smooth flow of the highway bridge and ensuring the safe travel of the people. Compared with adding support columns on both sides of the original independent pier, the steel clamp cap beam renovation measure has a fast construction speed, greatly saves the construction period, has less impact on traffic, is low in cost, aesthetically pleasing, and has a good renovation effect.
[0026] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
