[0001] This utility model relates to the field of bridge pier reinforcement technology, and in particular to a rapid-assembly bridge pier reinforcement cofferdam. Background Technology

[0002] In recent years, the construction technology of steel cofferdams for bridges has been widely applied to the fields of bridge foundation and pier reinforcement.

[0003] In existing technologies, common steel cofferdams include steel sheet pile cofferdams, steel caisson cofferdams, and double-walled steel cofferdams. These cofferdams often require specialized design to ensure that their bearing capacity, stiffness, stability, service life, and riverbed construction conditions meet construction requirements. Riverbed treatment is necessary before and after construction, and the placement of the cofferdam on the riverbed needs to be checked and adjusted as needed during construction. Therefore, the installation and dismantling of cofferdams are relatively complex, requiring large floating vessels and lifting equipment, and the material reuse rate is also very low.

[0031] Referring to Figures 1-9, this utility model discloses a rapidly assembled bridge pier reinforcement cofferdam, including a retaining assembly set around the bridge pier 14. Several support components are set on the side of the retaining assembly facing the bridge pier 14. Each support component is connected to a clamp 9 via a second connector, and the clamp 9 is fitted onto the bridge pier 14. The retaining assembly includes several straight steel plates 3, which are installed on a bearing platform 13 via a first connector. Adjacent straight steel plates 3 are connected by an arc steel plate 6. The support components include several H-shaped steels 8 arranged vertically and parallel to each other on the side of the straight steel plates 3 facing the bridge pier 14. Two adjacent H-shaped steels 8 on adjacent straight steel plates 3 and on the same plane are detachably connected by a connecting steel pipe.

[0032] This utility model, by placing the support component and the second connector between the enclosure component and the pier 14, and by placing the enclosure component on the pier cap 13 through the first connector, enables rapid assembly on the existing pier 14 and pier cap 13. This effectively solves the problems of multiple construction steps, long construction time, high construction cost, difficulty in floating and positioning, need for large floating vessels and lifting devices, and low material reuse rate in the prior art.

[0033] Further optimization of the scheme: the straight steel plate 3 includes several waler steel plates 32. The two outermost waler steel plates 32 are connected to the arc steel plate 6 by several fourth bolts 16. Several U-shaped steels 31 are installed on the side of the waler steel plates 32 facing the H-shaped steel 8. The U-shaped steels 31 are connected to the H-shaped steel 8 by brackets 7.

[0034] By using several fourth bolts 16, the two outermost waler steel plates 32 can be connected to the arc steel plate 6, which not only facilitates quick installation and disassembly, but also effectively encloses the pier 14.

[0035] The bracket 7 on the U-shaped steel 31 enables the H-shaped steel 8 to be effectively installed on the bracket 7.

[0036] In a further optimized design, a transverse steel plate 33 is fixedly connected between two adjacent U-shaped steels 31. The transverse steel plate 33 enables a stable connection between the two adjacent U-shaped steels 31.

[0037] In a further optimized design, two adjacent waler steel plates 32 are connected by several third bolts 15. These third bolts 15 allow for quick installation and removal of the two adjacent waler steel plates 32.

[0038] The design was further optimized so that the waler steel plate 32 is arranged in a U-shape, allowing adjacent waler steel plates 32 to effectively abut against each other.

[0039] To further optimize the design, a first water-stop rubber strip 5 is installed between two adjacent waler steel plates 32 and between the waler steel plate 32 and the arc steel plate 6.

[0040] The first water-stop rubber strip 5 enables effective sealing between two adjacent waler steel plates 32 and between the waler steel plate 32 and the arc steel plate 6.

[0041] To further optimize the design, a second water-stop rubber strip 34 is installed between the waler steel plate 32 and the U-shaped steel 31. The second water-stop rubber strip 34 enables effective sealing between the waler steel plate 32 and the U-shaped steel 31.

[0042] Further optimizing the design, the first connecting component includes a bottom steel pad 1 fixedly connected to the bearing platform 13, with an angle steel 2 fixedly connected to the bottom steel pad 1.

[0043] Further optimizing the design, the second connecting component includes a supporting steel pipe 11, with flanges 12 fixedly connected to both ends of the supporting steel pipe 11. The flanges 12 are detachably connected to the H-shaped steel 8 and the clamping component 9 via several fifth bolts 17. The use of several fifth bolts 17 facilitates the quick installation and disassembly of the supporting steel pipe 11.

[0044] The design is further optimized so that the clamp 9 includes symmetrically arranged side panels in a U-shape, and the two side panels are detachably connected by several second bolts 10. These second bolts 10 facilitate quick installation and removal of the side panels.

[0045] To effectively improve installation efficiency, the bottom steel pad 1, angle steel 2, arc steel plate 6, bracket 7, H-shaped steel 8, clamp 9, support steel pipe 11, U-shaped steel 31, waler steel plate 32, and horizontal steel plate 33 are prefabricated according to the actual construction dimensions and assembled on site.

[0046] Meanwhile, the first bolt 4, the second bolt 10, the third bolt 15, the fourth bolt 16, and the fifth bolt 17 facilitate on-site installation and disassembly.
