A concrete impermeability testing device

Abstract

This application relates to the field of permeability testing technology, and discloses a concrete permeability testing device, including a frame, annular seats, molds, a first hydraulic cylinder, a first lifting plate, a second hydraulic cylinder, a second lifting plate, circular plates, and supports. In use, the molds are placed upside down on multiple annular seats, allowing concrete specimens to be placed inside multiple cylinders. Then, controlling the operation of multiple second hydraulic cylinders moves multiple second lifting plates, ultimately causing multiple circular plates to press against multiple concrete specimens, thus pressing the specimens into the cylinders. Afterwards, the circular plates are reset, allowing the molds containing the concrete specimens to be placed upright. Controlling the first hydraulic cylinder then moves the lifting plates until they press against the multiple cylinders, ensuring a tight seal. Finally, water is supplied to the center of the annular seats for permeability testing, eliminating the need for other equipment to press the concrete specimens into the molds.

The second plate 12 includes a plurality of first through holes, each of which allows passage through the central portion of the annular seat 20. The annular seats 20 are mounted on the top surface of the second plate 12 and are coaxially distributed with the plurality of first through holes, respectively, for supporting and placing the molds 30.

Driven by multiple support columns 90, multiple circular plates 80 press against multiple concrete specimens, thus pressing the specimens into the cylinders 31. After resetting the circular plates 80, the mold 30 containing the concrete specimens is placed upright. Controlling the first hydraulic system moves the lifting plates until they press against multiple discs 32, ensuring a seal. Finally, water is supplied to the center of the annular seats 20 for permeability testing.
