[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0030] This invention provides a bridge pier anti-blast reinforcement and rapid repair device, including an adjusting ring 1, an extension rod 2, a weight 3, a connecting plate 4, and an auxiliary pier body 5. Multiple adjusting rings 1 are coaxially installed. The extension rod 2 is vertically placed and slidably connected to the adjusting rings 1. The weight 3 is coaxially installed with the adjusting rings 1. The extension rod 2 extends vertically downwards through the weight 3, simultaneously increasing the distance between the multiple adjusting rings 1, thereby covering the damaged area of ​​the bridge pier in the vertical direction. The auxiliary pier body 5 is connected to the adjusting rings 1 via the connecting plate 4. Multiple auxiliary pier bodies 5 are arranged in a circular array on the sidewall of the adjusting rings 1.

[0031] First, the coaxial installation of multiple adjusting rings 1 ensures the stability and reliability of the device. Under the vertical downward pull of the heavy object 3, multiple extension rods 2 can be elongated, thus enabling the overall structure to withstand external impacts. Second, the vertical placement of the extension rods 2, under the action of the heavy object 3, allows the device to quickly cover the damaged area of ​​the bridge pier to be repaired, thereby providing a framework for pouring concrete for rapid repair. The auxiliary pier body 5 further enhances the stability and support capacity of the device, effectively reducing the external impact force borne by the pier.

[0032] The adjusting ring 1 is provided with a sliding track 11 along its axis, and the sliding track 11 is arranged coaxially with the adjusting ring 1. The sliding track 11 is used to provide conditions for the extension rod 2 to slide. Since one end of the adjusting ring 1 is provided with a hinge shaft 12, when the damaged bridge needs emergency repair, such as when the bridge has partial damage, the adjusting ring 1 can be unfolded through the hinge shaft 12 to match the pier to be maintained. Since the sliding track 11 is set as a semi-open structure, that is, the position relative to the axis of the hinge shaft 12 is set as an opening, when the adjusting ring 1 hugs the pier, the extension rod 2 can be slid into the adjusting ring 1 and the end with the locking block 21 needs to be placed on the upper end of the adjusting ring 1, and the remaining part passes through the adjusting ring 1 and enters the sliding track 11.

[0033] The extension rod 2 is a telescopic structure. A locking block 21 is installed at the upper vertical end of the extension rod 2. The locking block 21 is spherical. The diameter of the locking block 21 is the same as the distance between the sliding rail 11. After the extension rod 2 slides into the sliding rail 11, because multiple adjusting rings 1 are coaxially arranged and the arc-shaped openings on their surfaces are of different sizes, and the end guards 111 at both ends are also provided with arc-shaped openings, the distance between the two arc-shaped openings combined with the distance between the end guards 111 can perfectly match the diameter of the spherical locking block 21. Since the sizes of the arc-shaped openings are different, before sliding to the matching arc-shaped opening, the adjusting ring 1 will be restricted within the sliding rail 11 of the first adjusting ring 1 due to the size of the spherical locking block 21.

[0034] The sliding track 11 has a retaining edge 111 at its upper vertical end. The spacing between the retaining edges 111 is the same as the outer diameter of the extension rod 2. The purpose of setting the retaining edges 111 and the extension rod 2 to have the same outer diameter is to allow the extension rod 2 to slide into the sliding track 11 when the adjusting ring 1 is fixed. The size of the locking block 21 is larger than the diameter of the extension rod 2, so the extension rod 2 can be locked in the adjusting ring 1.

[0035] The surface of the retaining edge 111 is provided with an arc-shaped groove 112, which is arranged in a ring around the adjusting ring 1. The arc-shaped groove 112 has two sizes and is arranged in a loop. The size includes A: the maximum diameter of the circle formed by the distance between the arc-shaped groove 112 and the retaining edge 111 is set to be the same as the diameter of the locking block 21, and size B: the maximum diameter of the circle formed by the distance between the arc-shaped groove 112 and the retaining edge 111 is located between the outer diameter of the extension rod 2 and the diameter of the locking block 21, excluding the two sides.

[0036] The number of arc-shaped grooves 112 of size A on the surface of the adjusting ring 1 decreases vertically downwards layer by layer.

[0037] The following is a feasible installation scheme: A three-layer adjusting ring 1 is provided. The first layer of adjusting ring 1 has 12 pairs of arc-shaped grooves 112, forming 12 circular holes. These 12 holes are grouped in sets of three. Each group of arc-shaped grooves 112 has two dimensions: A and B. Dimension A is where the maximum diameter of the circle formed by the distance between the arc-shaped groove 112 and the stop 111 is the same as the diameter of the locking block 21. Dimension B is where the maximum diameter of the circle formed by the distance between the arc-shaped groove 112 and the stop 111 is smaller than the diameter of the locking block 21, but larger than the outer diameter of the extension rod 2. The clockwise dimensions of the first layer of arc-shaped grooves 112 are: AAB, AAB, A... AB, AAB; the second layer of arc groove 112 is set clockwise as follows: ABB, ABB, ABB, ABB; the third layer of arc groove 112 is set clockwise as follows: BBB, BBB, BBB, BBB; thus ensuring that when the extension rod 2 slides to the fixed position, it can fall into the adjustment ring 1 of the next layer. As for the arc groove 112 of size B in the first layer, since the locking block 21 is too large, it will be stuck in the position under the pull of the weight of the heavy object 3. At the same time, combined with the arc groove 112 of size B, the extension rod 2 is fixed in the position, ensuring the position of each extension rod 2, thereby ensuring that the subsequent concrete pouring process is stable enough.

[0038] One end of the adjusting ring 1 is provided with a hinge shaft 12 and a nail shear force connector 13 is installed on its side wall. The hinge shaft 12 allows the adjusting ring 1 to adapt to piers with different degrees of damage. It can also be opened and closed through the hinge shaft 12 for welding to adapt to piers of different shapes and sizes, thereby enhancing the stability and adaptability of the connection. The installation of the nail shear force connector 13 improves the load-bearing capacity and connection stability of the adjusting ring 1, enabling the device to more effectively resist external impacts and pressures, and improving the applicability and reliability of the device. At the same time, it reduces the difficulty of construction workers' work, making the installation and adjustment process simpler, thereby improving construction efficiency and ease of operation.

[0039] The connecting plate 4 includes a side plate 41, a ring plate 42, and a support frame 43; the ring plate 42 is coaxially connected to the auxiliary pier body 5, and the ring plate 42 is fixedly connected to the adjusting ring 1 through the side plate 41; the support frame 43 is cross-installed between the adjusting ring 1 and the auxiliary pier body 5.

[0040] The structural combination of side plate 41, ring plate 42, and support frame 43 provides strong support and fixing force, enabling the device to more firmly connect and support the adjusting ring 1 and the auxiliary pier 5. The ring plate 42 is coaxially connected with the auxiliary pier 5, ensuring the stability and reliability of the device. At the same time, the fixed connection between the side plate 41 and the adjusting ring 1 further strengthens the structural integrity and impact resistance of the device. In addition, the cross-installation of the support frame 43 between the adjusting ring 1 and the auxiliary pier 5 effectively increases the support area and load-bearing capacity of the device, improving its resistance to external impact. The support frame 43 can controllably adjust the angle of the intersection of the two support frames 43 according to the position of the adjusting ring 1, thereby adapting to the pier under different working conditions. For example, on slopes, the piers that need to be maintained or reinforced can be fixed by adjusting the length of the auxiliary pier 5.

[0041] The overall working process is as follows: When the bridge pier encounters a special situation requiring maintenance, due to partial damage, concrete cannot be poured directly. Therefore, the adjusting ring 1 is opened through the hinge shaft 12, and the adjusting ring 1 clamps the upper end of the area to be maintained. Then, multiple extension rods 2 are slid into the sliding track 11. Due to the setting of the arc grooves 112 of sizes A and B, under the pull of the weight 3, the extension rods 2 will slide down and extend one by one. At the same time, under the regular arrangement of the arc grooves 112, a gradient extension rod 2 is formed. Different adjusting rings 1 are arranged as needed, so that the area to be maintained is completely covered. Then, the clamping ring is fixed by welding, and the side plate 41 and ring plate 42 are welded. According to the height difference of the adjusting rings 1, the cross support frame 43 is welded. Under the coverage of the extension rods 2, concrete is poured.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
