Abstract

The invention discloses a microbial corrosion device for simulating hydraulic concrete under different conditions. The device comprises an upper-layer water storage tank and a lower-layer water storage tank. N first partition plates are arranged in the upper-layer water storage tank in parallel in a first direction to divide the upper-layer water storage tank into N+1 first unit structures. Each first unit structure is divided into a reaction area and a transition area by a second partition plate in the upper-layer water storage tank in a second direction. N third partition plates are arrangedin the lower-layer water storage tank in parallel in the first direction to divide the lower-layer water storage tank into N+1 second unit structures. Grooves for placing concrete pieces under test are formed in the reaction areas. Each transition area is communicated to a water inlet of the corresponding reaction area, and a water outlet of each reaction area is communicated to the second unit structure at the corresponding position in the lower-layer water storage tank. A water outlet of each second unit structure is communicated with a water inlet of the transition area of the first unit structure at the corresponding position, and a circulating water pump is arranged at the water outlet of each second unit structure.

Description

technical field [0001] The invention relates to an experimental device for microbial corrosion of concrete, in particular to a microbial corrosion device for simulating hydraulic concrete under different conditions. Background technique [0002] Hydraulic engineering is an important infrastructure for the development of modern society. As an important part of it, hydraulic structures are mostly concrete or reinforced concrete structures. During long-term service, they are subject to multiple effects such as water erosion, sea tide erosion, and microbial corrosion. The structural integrity of concrete affects the safe operation of hydraulic projects. At present, water conservancy projects in all countries in the world have problems such as structural aging and shortened service life. [0003] Hydraulic concrete is in a humid environment for a long time, and the surface is easy to absorb nutrients in the water body, thus providing favorable conditions for the growth of microo...
