Description

Technical Field

[0001] The utility model relates to the field of concrete impermeability detection equipment, in particular to a concrete impermeability detection device. Background Technique

[0002] Concrete, usually simply referred to as "concrete", is an engineering composite material in which a binder cements aggregates into a whole. It is mainly composed of raw materials such as cement, aggregate, coarse aggregate and water, which are mixed in a certain proportion. It has various excellent properties, such as mechanical properties such as compressive, tensile, bending and shear resistance, as well as certain physical properties such as density, water absorption and dry shrinkage.

[0003] At present, when concrete is used in a special environment, it is necessary to detect the impermeability of concrete in advance through an impermeability detection device. When the existing concrete impermeability detection device is in use, the operator first places the test mold in the installation hole, and then the driving mechanism drives each group of clamping blocks to clamp the test mold. After clamping the test mold, the impermeability performance test can be started. During the test process, any start-stop switch can be pressed at any time to take out the test mold corresponding to the start-stop switch, which will not affect the other test molds. After the impermeability performance test of the concrete is completed, it is necessary to take out the concrete from the test mold. However, after the existing concrete has completed the impermeability performance test, when the concrete is in the test mold, the operator will use tools such as a scraper and a plastic plate to gently pry along the contact surface between the specimen and the test mold, and gradually take out the specimen from the test mold, which may cause the demolding process to be time-consuming and cumbersome, reduce the overall test efficiency, and may cause damage to the specimen due to improper operation or improper force control.
