After the device is used for simulating corroded reinforced concrete components in a wave splashing area in the sea environment, the interference of human factors can be greatly reduced, the test process can be controlled according to the test result, the test result can better represent actual environment of the site, and the test result is reliable. The device is applicable to tests of sample in different sizes and can carry out simulation of wave splashing conditions of small samples as well as mass reinforced concrete.

Description

technical field [0001] The invention belongs to the technical field of test equipment, and in particular relates to a test equipment for simulating corrosion of reinforced concrete structures in seawater splashing environment. Background technique [0002] Concrete structures in marine environments are very common for steel corrosion caused by chloride ions in seawater to cause structural damage. The phenomenon of damage caused by the reaction of alkali aggregates. Tianjin Xingang built 25 berths from 1958 to 1985. The coastline is as long as 6000m. year. [0003] The factors affecting the durability of concrete structures in seawater environments are very complex, such as structural exposure time, tidal changes, ambient temperature, seawater salinity, and exposure locations (atmospheric areas, splash areas, water level fluctuation areas, underwater areas) and other factors will affect the structure. has a huge impact on durability. [0004] The manufacturing methods of t...

Problems solved by technology

[0004] The manufacturing methods of the rusted components needed to study the durability of concrete materials and structures are: full-wet method, semi-wet method, etc. However, the rusted components used in the laboratory obtained by using these methods have large errors, because the concrete structure in the ocean The corrosion situation is more complex and needs to be determined by multiple factors such as chloride ions, moisture, oxygen, and carbon dioxide. The above methods cannot well simulate the real situation of concrete structures in the splash zone. In order to study the real situation in the splash zone, researchers often use The test components are placed in the real marine environment. However, this environment has great disadvantages, such as small components, easy to lose in the marine environment, slow corrosion rate, high production costs, and high transportation costs. , the labor cost is high, in addition, it is also controlled by non-human factors such as typhoon and big waves

The above conditions greatly limit people's research on corroded reinforced concrete members in the splash zone.
