Description

Technical Field

[0002] Precast concrete bricks are made of cement and aggregate as the main raw materials, and are made through processing, vibration pressurization or other molding processes. They are used for paving concrete pavements and ground engineering blocks and slabs of urban road sidewalks, urban squares, etc. During their preparation process, the permeability is generally tested by a detection device to verify the quality of the precast concrete bricks, thereby ensuring the stability and safety of the concrete building structure. For testing the permeability of precast concrete bricks, water is generally allowed to penetrate into the precast concrete bricks, and then the flow velocity v2 through the precast concrete bricks can be obtained through the length L of the precast concrete bricks, the cross-sectional area A1 of the water inlet pipe and the cross-sectional area A2 of the precast concrete bricks; the permeability coefficient K of the sample is then calculated by Darcy's law, thereby being able to obtain a more accurate permeability rate.

[0003] The existing precast concrete brick permeability rate testing device lacks a fixing device for the precast concrete bricks when it is installed and used. Therefore, during the test, the bricks may slip or be damaged due to lack of fixing, which will lead to inaccurate test data. In addition, the water used in the precast concrete brick permeability rate test is difficult to recycle, which will cause waste and bring certain adverse effects to people's use process. In order to solve the shortcomings of the prior art, we propose a precast concrete brick permeability rate rapid testing device. Utility Model Content
