[0004] The technical scheme adopted by the utility model is as follows:

[0005] A quick-mounting type protection device of pier column is used to surround the lower part of the pier column, which is composed of several fan-shaped prefabricated units. Each prefabricated unit includes an inner arc plate, an outer arc plate, a side plate, and a reinforcing plate. The side plate is connected between the end portions of the inner arc plate and the outer arc plate. The inner arc plate, the outer arc plate, and the side plates at both ends form a fan-shaped cavity. The reinforcing plate is distributed within the cavity and connected between the inner arc plate and the outer arc plate. The side plate has bolt holes for cooperating with bolts. When two adjacent prefabricated units are spliced, the side plates are attached together and fixed by bolts.

[0006] Preferably, the prefabricated unit is made of rubber material.

[0007] Preferably, the prefabricated unit is made of concrete material.

[0008] Preferably, the prefabricated unit is made of plastic material.

[0009] Preferably, a steel backing plate is provided at the position of the bolt hole on one side of the side plate within the cavity.

[0010] Preferably, one of the reinforcing plates is at the center of the inner arc plate and the outer arc plate, and the remaining reinforcing plates are symmetrically distributed about the center position of the reinforcing plate.

[0011] Preferably, the bolt holes are vertically arrayed along the side plate.

[0012] The utility model has the following beneficial effects:

[0013] The device does not need cast-in-place, and only needs to be spliced on site to quickly surround the lower part of the pier column to play a protective role, so the construction period is short, and once a certain prefabricated unit is damaged and fails, the damaged prefabricated unit can be directly replaced without overall replacement, so the maintenance is simple and the cost is low. In each prefabricated unit, the cavity can reduce the amount of material used, and after the self-weight is reduced, it is also convenient to load and unload, and in the case of need, sand, stone, water and other substances can be filled in the cavity to enhance the protection capacity; in each prefabricated unit, the reinforcing plate can compensate to a certain extent for the strength reduction caused by the larger size of the cavity, and ensure the structural strength.

[0018] The present application will be further described below in conjunction with the drawings and examples.

[0019] The present application discloses a fast-assembled protective device of a pier column, as shown in Figure 1 for surrounding the lower part of the pier column, which is spliced by a plurality of fan-shaped prefabricated units 1; as shown in Figures 1 to 3 Each prefabricated unit 1 includes an inner arc plate 11, an outer arc plate 12, a side plate 13 and a reinforcing plate 14, the side plate 13 is connected between the end portions of the inner arc plate 11 and the outer arc plate 12, the inner arc plate 11, the outer arc plate 12 and the side plates 13 at both ends form a fan-shaped cavity, the reinforcing plate 14 is distributed in the cavity and connected between the inner arc plate 11 and the outer arc plate 12, and the side plate 13 is distributed with bolt holes 16 for cooperating with bolts; as Figure 1As shown, when two adjacent prefabricated units 1 are spliced, the side plates 13 are attached together and fixed by bolt connection. The device does not need cast-in-place, but only needs to be spliced on site to quickly surround the lower part of the pier column to play a protective role, so the construction period is short, and once a prefabricated unit 1 is damaged and fails, it does not need to be replaced as a whole, but only the damaged prefabricated unit 1 needs to be replaced, so the maintenance is simple and the cost is low. In each prefabricated unit 1, the cavity can reduce the amount of material used, and after the self-weight is reduced, it is also convenient to load and unload, and in the case of need, sand, stone, water and other substances can be filled in the cavity to enhance the protection capacity; In each prefabricated unit 1, the reinforcing plate 14 can compensate to a certain extent for the reduction in strength caused by the large size of the cavity, thereby ensuring the structural strength.

[0020] As shown in the drawings, Figures 1 to 3 In this embodiment, preferably, a steel backing plate 15 is arranged at the position of one side bolt hole 16 in the cavity of the side plate 13, which can avoid the damage caused by the locking force of the bolt concentrated on the side plate 13.

[0021] As shown in the drawings, Figures 1 to 3 In this embodiment, preferably, one of the reinforcing plates 14 is located at the center of the inner arc plate 11 and the outer arc plate 12, and the remaining reinforcing plates 14 are symmetrically distributed about the center position of the reinforcing plate 14, which makes the structural strength more uniform.

[0022] As shown in the drawings, Figure 3 In this embodiment, preferably, the bolt holes 16 are vertically arrayed along the side plate 13, which makes the connection more reliable.
