This utility model belongs to the field of bridge
pier safety protection and discloses a reinforcement device for bridge piers to
resist erosion. It includes a permeable protective
barrel, which is fitted around the bridge
pier to form an annular cavity. The cavity is filled with a filler material tightly adhering to the outer wall of the bridge
pier. The top of the permeable protective
barrel is sealed with a
concrete cover. The protective
barrel is composed of multiple vertically spliced prefabricated sections, each with multiple circumferential openings on its sidewalls. These openings allow
water flow to partially penetrate rather than directly
impact the bridge pier, effectively dispersing
water energy and slowing down the downstream
water flow velocity, thereby inhibiting
sediment initiation and localized
erosion. The filler material fits tightly against the bridge pier, providing lateral support and reinforcement, enhancing the overall stability of the bridge pier. The
concrete cover and prefabricated section structure ensure the device's airtightness and modular convenience, facilitating construction, installation, and subsequent maintenance. This device can simultaneously achieve the dual goals of
erosion prevention and bridge pier reinforcement, significantly improving the durability and safety performance of the bridge pier and avoiding the limitations of existing technologies with only single functions.
