Automatic pressure-regulating concrete impermeability instrument

Abstract

The invention relates to an automatic pressure regulating concrete impermeability instrument, and relates to the field of concrete impermeability. Th eautomatic pressure regulating concrete impermeability instrument comprises an impermeability instrument body; a concrete test mold arranged on the impermeability instrument body through a flange and used for containing concrete blocks; and a supporting plate which is fixed on the inner wall of the concrete test mold and is used for supporting the concrete block; wherein a through hole is formed in the supporting plate, and the supporting plate and the concrete test mold are coaxial; a plurality of first grooves and a plurality of second grooves are formed in the supporting plate, the first grooves and the second grooves are located in the end face, away from the anti-permeability instrument body, of the supporting plate, the first grooves are annular grooves, the first grooves are distributed outwards along the axis of the supporting plate and are coaxial, the second grooves are linear grooves, the second grooves are distributed in the radial direction of the supporting plate, the multiple second grooves are evenly distributed along the axis of the supporting plate, the second grooves communicate with the multiple first grooves, and the second grooves communicate with the through holes in the supporting plate. According to the invention, the accuracy of concrete block impermeability test data is improved.

Description

technical field [0001] The application relates to the field of concrete anti-seepage, in particular to an automatic pressure-regulating concrete anti-seepage instrument. Background technique [0002] Concrete, artificial stone widely used in construction, for some buildings, such as hydraulic construction, underwater, underwater, underground and other construction projects, buildings are required to have special properties - impermeability performance The so-called impermeability Performance refers to the ability of the materials used in structures to resist the penetration of water and / or other liquid (light oil, heavy oil) media under pressure. HS-4 type impermeability tester is mainly used for the test of concrete impermeability performance and the determination of impermeability grade. At the same time, it can also be used for the measurement and quality inspection of the air permeability of building materials, so it has been widely used in production, construction, des...

Problems solved by technology

[0003] The concrete anti-seepage instrument is also called the concrete anti-seepage instrument. During the use of the concrete anti-seepage instrument, when the concrete block is tested for impermeability, the concrete block is directly put into the concrete test mold on the concrete anti-seepage instrument. , the bottom of the concrete block hits the body of the impermeability instrument directly, which makes the bottom of the concrete block prone to damage, which in turn affects the accuracy of the concrete block impermeability test data
