Description

Technical Field

[0001] The present application relates to the technical field of anti-penetration detection, and specifically to a concrete anti-penetration detection device. Background Art

[0002] Concrete is a building material widely used in construction. Due to its low price and simple production process, the use of concrete is increasing. However, current construction projects usually require buildings to have certain anti-seepage properties, so detection devices are usually needed to test the anti-seepage properties of concrete.

[0003] Chinese utility model patent publication number CN220508669U discloses a concrete performance testing device for concrete preparation, comprising a testing frame, a separator unit, a concrete block, and a pressure testing unit, as well as an elastic fixing unit and a liquid receiving unit. The elastic fixing unit comprises a slider movably disposed within the separator unit, and two side fixing plates fixedly connected to the top of the slider for elastically clamping the concrete block. The liquid receiving unit comprises a conical funnel fixedly connected to the center of the bottom of the separator unit, and a liquid receiving tube disposed directly below the conical funnel for receiving seepage liquid. This utility model is a concrete performance testing device for concrete preparation. When a concrete block fails to meet strength requirements and breaks and deforms, elastic fixing reduces structural damage and testing costs. The liquid receiving tube is easily disassembled and assembled, and the presence and amount of water in the liquid receiving tube are observed to determine the concrete's anti-permeability performance.

[0004] The device is provided with a detection frame, and a partition unit is provided on the inner wall of the detection frame. A slider is movably provided inside the partition unit, and a side fixing plate is fixedly connected to the top of the slider. When performing penetration testing, the staff installs the concrete block on the top of the partition unit and then clamps the concrete plate through the side fixing plate. However, after the concrete is injected with external water source, part of the water after penetration will be adsorbed in the partition plate and the chute. The liquid receiving test tube does not completely collect the penetrated water, and the detection accuracy is not high. Utility Model Content
