[0002] A concrete permeameter is a key experimental device specifically designed to determine the water permeability resistance of concrete. It works by simulating the water pressure environment experienced by concrete in actual engineering projects to evaluate the concrete's impermeability.

[0003] In existing technologies, such as a concrete permeameter with publication number CN222837967U, impurities and dust entering the transport pipe can be blocked by setting a screen, thereby avoiding the situation where the transport pipe is blocked and affects the test results.

[0004] However, it also has some shortcomings, such as the inconvenience of disassembling and assembling the mounting base, which makes it inconvenient to maintain the concrete permeameter. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a concrete permeameter that is easy to assemble and disassemble.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a concrete permeameter, including a table and multiple test mold components set on the table for testing concrete, and a water supply device for supplying water to the test mold components. Each test mold component includes a water outlet mold base, which is detachably installed on the top of the table by bolts. The top of the water outlet mold base has a receiving groove. A water inlet pipe is installed at the bottom of the water outlet mold base, and the bottom of the water inlet pipe extends out of the bottom of the table. The top of the water inlet pipe communicates with the receiving groove, and the bottom of the water inlet pipe is connected to the water supply device. A test cylinder has a connecting seat at the bottom of the test cylinder that connects to the water outlet mold base. The connecting seat and the test cylinder are integrally formed and detachably connected by bolts. An elastic cylinder is provided in the test cylinder, and a sealing ring is provided at the bottom of the elastic cylinder. The sealing ring is integrally formed with the elastic cylinder and is located between the water outlet mold base and the connecting seat.

[0007] A further preferred embodiment of this utility model is: the top of the table body is provided with a groove for accommodating the water outlet mold base, and the bottom of the groove is provided with a through hole for the water inlet pipe to pass through.

[0008] A further preferred embodiment of this utility model is: a filter screen is provided in the receiving groove, and the filter screen is detachably installed in the receiving groove by bolts.

[0009] A further preferred embodiment of this utility model is as follows: a water collection trough is provided on the top of the table body, and a water outlet pipe is provided at the bottom of the table body, with the top of the water outlet pipe connected to the water collection trough.

[0010] A further preferred embodiment of this utility model is: a limiting groove for restricting the movement of the elastic cylinder is provided on the inner wall of the test cylinder.

[0011] A further preferred embodiment of this utility model is that the water inlet pipe and the water outlet mold base are integrally formed.

[0012] A further preferred embodiment of this utility model is that the elastic cylinder and the sealing ring are made of uniform rubber material, and the elastic cylinder is detachably connected to the test cylinder.

[0013] Compared with the prior art, the advantages of this utility model are that when it is necessary to disassemble and assemble the water outlet mold base, it is only necessary to remove the bolts from the water outlet mold base or tighten the bolts on the water outlet mold base. This makes it convenient to disassemble and assemble the water outlet mold base. Then, a receiving groove is opened on the top of the water outlet mold base, and a water inlet pipe is set at the bottom of the water outlet mold base, which extends out of the bottom of the table body and connects to the output end of the water supply device. The top of the water inlet pipe is connected to the receiving groove. Then, a test cylinder for holding concrete specimens is set on the water outlet mold base. In order to facilitate the connection between the test cylinder and the water outlet mold base, a connecting seat is set at the bottom of the test cylinder, which can be detachably connected to the water outlet mold base by bolts. This facilitates the disassembly and assembly of the test cylinder and the water outlet mold base, and thus facilitates the disassembly and assembly of the concrete permeameter, as well as the maintenance of the concrete permeameter.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0026] This embodiment mainly describes the structure of a concrete permeameter, as follows:

[0027] like Figures 1-8 As shown, a concrete permeameter includes a table 1 and multiple mold components 2 mounted on the table 1 for testing concrete, as well as a water supply device for supplying water to the mold components 2. When the concrete permeameter is in use, the concrete specimen to be tested is fixed by the mold components 2 located on the table 1. Then, the output end of the water supply device is connected to the mold components 2, and the water supply device is activated to supply water and pressurize it into the mold components 2. This achieves the testing of the concrete specimen's impermeability. The water supply device is existing mature technology and is therefore not described in detail (as described in the water supply device in the published patent with publication number CN210923411U).

[0028] The trial mold assembly 2 includes a water outlet mold base 21 that is detachably mounted on the top of the table body 1 by bolts. This allows for easy disassembly and assembly of the water outlet mold base 21 by simply removing the bolts from or tightening them. A receiving groove 28 is provided at the top of the water outlet mold base 21, and a water inlet pipe is provided at the bottom of the water outlet mold base 21, extending through the bottom of the table body 1 and connecting to the output end of the water supply device. 26, and the top of the inlet pipe 26 is connected to the receiving tank 28. A test cylinder 22 for holding concrete specimens is set on the outlet mold base 21. To facilitate the connection between the test cylinder 22 and the outlet mold base 21, a connecting seat 23 is provided at the bottom of the test cylinder 22, which is detachably connected to the outlet mold base 21 by bolts. This facilitates the assembly and disassembly of the test cylinder 22 and the outlet mold base 21, thereby facilitating the assembly and disassembly of the concrete permeameter and its maintenance. Furthermore, to ensure… The connection strength between the connecting seat 23 and the test cylinder 22 is ensured by the integral molding of the connecting seat 23 and the test cylinder 22. Finally, to ensure the sealing performance when the outer wall of the concrete specimen abuts against the inner wall of the test cylinder 22, an elastic cylinder 25 covering the concrete specimen is provided in the test cylinder 22. At the same time, to ensure the sealing performance when the test cylinder 22 is connected to the water outlet mold base 21, a sealing ring 24 is provided at the bottom of the elastic cylinder 25, and the sealing ring 24 is located between the water outlet mold base 21 and the connecting seat 23. Thus, when the test cylinder 22 is installed on the water outlet mold base 21, the connecting seat 23 at the bottom of the test cylinder 22 can press the sealing ring 24. At the same time, to ensure the reliability of the connection between the sealing ring 24 and the elastic cylinder 25, the sealing ring 24 and the elastic cylinder 25 are integrally molded. In addition, to ensure the sealing effect of the elastic cylinder 25 and the sealing ring 24, the elastic cylinder 25 and the sealing ring 24 are made of uniform rubber material. At the same time, to facilitate the replacement of the elastic cylinder 25, the elastic cylinder 25 and the test cylinder 22 are detachably connected.

[0029] Furthermore, in order to facilitate the installation of the water outlet mold base 21, a groove 13 is provided on the top of the table body 1 to accommodate the water outlet mold base 21. At the same time, in order to facilitate the water inlet pipe 26 to pass through the table body 1, a through hole 14 is provided at the bottom of the groove 13 for the water inlet pipe 26 to pass through.

[0030] Furthermore, to prevent the water inlet pipe 26 from being blocked by impurities, a filter screen 27 is provided in the receiving tank 28 to block impurities. At the same time, in order to facilitate the maintenance of the filter screen 27, the filter screen 27 is detachably installed in the receiving tank 28 by bolts, and multiple installation slots 29 are provided in the receiving tank 28 to facilitate the installation of the filter screen 27.

[0031] Furthermore, in order to ensure the strength of the connection between the water inlet pipe 26 and the water outlet mold base 21, the water inlet pipe 26 and the water outlet mold base 21 are integrally formed.

[0032] Furthermore, in order to improve the reliability of the elastic cylinder 25 in the test cylinder 22, a limiting groove 221 is provided on the inner wall of the test cylinder 22 to restrict the movement of the elastic cylinder 25.

[0033] Furthermore, in order to prevent the water used for testing from overflowing from the top of the test tube 22 and flowing directly from the table body 1 to the ground, a water collection tank 12 is provided on the top of the table body 1, and a water outlet pipe 11 connected to the water collection tank 12 is provided at the bottom of the table body 1.
