Abstract
Description
technical field
[0001] The invention relates to a test device for the water penetration resistance of the joints of new and old concrete structures caused by construction intervals. Background technique
[0002] In the civil engineering industry, there are parts where there are joints in the concrete structure due to the construction interval, such as the concrete joints and post-casting strips in the basement, the subway station structure with a laminated wall structure, and the joints of the fabricated underground structure Parts, concrete stubble parts of underground passages, post-repair parts of other engineering structures, etc. When these engineering structures are located below the groundwater level, these joints are often the places where the leakage is relatively concentrated during the operation and use stage, which has a great impact on the later use of the structure and the durability of the concrete, and will also cause certain damage. In serious cases, it may...
