[0023] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0024] Example 1:

[0025] The preferred embodiment of the present invention provides a bridge pier protection structure with anti-wear performance, such as Figure 1 As shown, it includes a base 1 and a pier 2 arranged on the base 1. More than one pier 2 can be arranged on the base 1. A leveling layer 3 is arranged on the outside of the cement structure of the base 1 and the pier 2. The leveling layer 3 is mainly used for leveling the surface to facilitate the subsequent setting of the coating. An elastic layer 4 is arranged on the lower part of the pier 2 and the leveling layer 3 of the base 1. The elastic layer 4 is used to resist scouring and the impact of sand and gravel in the water flow, which can effectively avoid direct damage to the cement base. A protective layer 5 is arranged on the upper part of the pier 2. The upper part of the pier 2 mainly refers to the remaining area above the water level that is not covered by the elastic layer 4. The protective layer 5 is mainly used to prevent weathering and corrosion and prevent the cement strength from decreasing. The leveling layer 3 adopts high-strength and wear-resistant material. The elastic layer 4 is a flexible protective elastomer formed by multiple applications of primer and topcoat. Of course, other similar materials can also be used as long as they meet the requirements.

[0026] The elastic layer 4 is based on the upper surface of the base 1, and the height requirement is greater than 2 m. 2 m is considered as the basic height requirement considering the depth of most water areas. Of course, for shallower locations, the height can also be appropriately reduced, such as being set to 1.5 m. Of course, the elastic layer 4 requires being higher than the highest water level during the flood season to avoid the water level rising during the flood season causing inadequate protection. If necessary, historical maximum water level and average water level data can be referred to.

[0027] The protective layer 5 is formed by multiple coatings of silica enamel paint. The thickness of the elastic protective layer 5 meets the protection function, so thick coating and multiple coating are required. Of course, other ways can also be used to realize the silica enamel coating, such as pasting.

[0028] The elastic layer 4 coats all surfaces of the base 1 that are in contact with the water flow, specifically the upper surface and the side surface. The elastic layer 4 corresponds to all positions that may be subjected to water flow erosion. The base 1 of the utility model is a cuboid, so all positions except the bottom buried position need to be covered.

[0029] The thickness of the leveling layer 3 is 2 mm or more, the thickness of the elastic layer 4 is 3 mm or more, and the thickness of the protective layer 5 is 1 mm or more. Of course, the thickness is only a relatively reasonable limit. The thickness cannot be too thick. Generally, it is required to be no more than 10 mm to avoid increasing the risk of falling off and to consider the overall adsorption capacity to ensure the service life.

[0030] Example 2:

[0031] As Figures 1-3 A bridge pier protection structure with anti-erosion performance includes a base 1 and a bridge pier 2 arranged on the base 1. One or more bridge piers 2 can be arranged on the base 1. A leveling layer 3 is arranged outside the cement structure of the base 1 and the bridge pier 2. The leveling layer 3 is mainly used for surface leveling to facilitate the subsequent arrangement of the coating layer. An elastic layer 4 is arranged on the leveling layer 3 at the lower part of the bridge pier 2 and the base 1. The elastic layer 4 is used to resist erosion and the impact of sand and stones in the water flow, which can effectively avoid damage to the cement base. A protective layer 5 is arranged on the upper part of the bridge pier 2. The upper part of the bridge pier 2 mainly refers to the area above the water level and not covered by the elastic layer 4. The protective layer 5 is mainly used to prevent wind and corrosion to prevent the reduction of cement strength. The leveling layer 3 is made of high-strength anti-erosion material. The elastic layer 4 is a flexible protective elastomer formed by multiple coatings of primer and finish. Of course, other similar materials can also be used as long as they meet the requirements. If necessary, the elastic layer 4 can also be arranged outside the protective layer 5 to facilitate the realization of stronger protection capability and facilitate construction.

[0032] It should be noted that the damaged base 1 and pier 2 are repaired by using a repair material to form a repair layer 6 on the cement structure, and a leveling layer 3 is coated on the basis of the repair layer 6, the repair layer 6 is mainly used for repairing the damaged cement base, repairing the base and ensuring the flatness of the subsequent leveling layer 3, the repair layer and the leveling layer 3 can use the same material, of course, different materials can also be used, the repair layer is mainly used for repairing the main body of the cement base, if necessary, the seriously damaged and falling position can be stripped and then repaired to form the repair layer 6, and the repair layer 6 can be re-anchored if necessary. The repair layer 6 is locally filled in the gap position by using high-strength wear-resistant cement, so that the surface of the cement base is complete.

[0033] The elastic layer 4 is based on the upper surface of the base 1, and the height requirement is greater than 2m, and 2m is considered as a basic height requirement considering the depth of most water areas, of course, the height can be appropriately reduced for relatively shallow positions, such as being set to 1.5m. Of course, the elastic layer 4 is required to be higher than the highest water level in the flood season, so as to avoid the water level rising in the flood season to cause insufficient protection, if necessary, historical highest water level and average water level data can be referred to.

[0034] The protective layer 5 is formed by multiple coating of silica glaze paint, and the thickness of the elastic protective layer 5 meets the protection function, so that thick coating and multiple coating are required, of course, other ways such as pasting can also be used to realize the silica glaze coating.

[0035] The elastic layer 4 is coated on all surfaces of the base 1 in contact with the water flow, specifically the upper surface and the side surface, that is, the elastic layer 4 corresponds to all positions that may be subjected to water flow erosion, and the base 1 of the utility model is a cuboid, so all positions except the bottom buried position need to be covered.

[0036] The thickness of the leveling layer 3 is more than 2mm, the thickness of the elastic layer 4 is more than 3mm, and the thickness of the protective layer 5 is more than 1mm, of course, the thickness is only a relatively reasonable limit, and the thickness cannot be too thick, generally not more than 10mm, so as to avoid increasing the falling risk, and the overall adsorption capacity needs to be considered to ensure the service life.

[0037] The above only describes the preferred embodiment of the utility model, and does not limit the protection scope of the utility model, any modification, equivalent replacement and improvement made by any person skilled in the art within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
