Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge protection plates, in particular to a bridge horseshoe protection plate. Background Art
[0002] The existing bridge crash barrier is constructed of cast-in-place reinforced concrete. Both the crash barrier's impact surface and the horseshoe section exhibit surface spalling and deterioration. This spalling and deterioration is caused by the application of deicing agents during winter snow removal and maintenance. The salts in the deicing agents corrode the concrete, causing surface degradation and spalling.
[0003] In existing technologies, spalling of the concrete surface above the horseshoe section is caused by insufficient steel reinforcement protection. Under the influence of rain and natural factors, the steel rusts and expands, causing cracking and spalling of the concrete surface. To mitigate the effects of long-term corrosion from the natural environment and deicing agents on the concrete of the crash barrier and to ensure its protective capabilities, a plan was proposed to protect the crash barrier, resulting in the development of a bridge horseshoe protection plate. Utility Model Content
