Description

Concrete impermeability test device for hydraulic engineering quality detection Technical Field The invention belongs to the technical field of concrete testing, and particularly relates to a concrete impermeability test device for hydraulic engineering quality detection. Background In the field of hydraulic engineering construction, the impermeability of concrete is one of the core indexes for measuring engineering quality, and is directly related to the impermeability effect and long-term durability of water conservancy facilities such as dykes and dams, channels, water gates and the like. Therefore, before and during the construction of the hydraulic engineering, the impermeability of the concrete test piece is detected by a professional impermeability test device, so that the concrete material is ensured to meet the engineering design requirement. At present, a concrete impermeability test device commonly used in industry is mostly composed of a fixed frame, an integrated test die (a placement part) and a simple pressurizing structure, and has the obvious pain point that a test piece is easy to damage in disassembly in the practical application process, so that the subsequent analysis is influenced. Because the concrete test piece can appear bleeding and segregation phenomenon in the shaping in-process, the test piece surface is liable to form adsorption affinity with the test die inner wall, and current integral test die need be peeled off by force with the help of tools such as crowbar, hammer when dismantling, and not only operation consuming time still easily leads to the test piece edge damage, surface cracking, destroys the test piece integrality. If the test piece is seriously damaged, the accuracy of the anti-permeability test result can be directly affected, and even the test piece needs to be prepared again, so that the detection cost and the time cost are increased. In view of the shortcomings of the existing concrete impermeability test device in terms of operation flexibility, test piece protection and the like, a novel impermeability test device capable of solving the pain points is needed.
