Description

Technical Field

[0001] This utility model belongs to the technical field of concrete testing equipment, specifically relating to a permeability testing machine. Background Technology

[0002] Concrete is a type of artificial stone widely used in modern construction. For certain buildings, such as hydraulic structures, underwater structures, underground structures, and other construction projects, concrete structures are required to have special properties—permeability resistance. Permeability resistance refers to the ability of concrete to resist the penetration of water or other liquids (light oil, heavy oil, etc.) under pressure.

[0003] A concrete permeability tester is an instrument used to test the waterproof performance of hardened concrete and determine its permeability grade. It is an essential measuring instrument for premixed concrete manufacturers and construction engineering quality testing laboratories. The concrete permeability tester utilizes a sealed container and its connected piping system to ensure equal pressure at all points (ignoring water head), pressurized by a water pump, and maintained within a specified pressure range by an intelligent digital control gauge. Concrete permeability testing is a lengthy process; existing concrete permeability testers can only perform one set of tests at a time, resulting in low testing efficiency. Utility Model Content

[0026] The following is combined with Figures 1-4 This utility model will be described in detail.

[0027] Example:

[0028] A permeability testing machine, in some embodiments, such as Figures 1-4As shown, the system includes a placement frame 1, which comprises an upper top plate 2 and a lower top plate 3. The upper top plate 2 and the lower top plate 3 are connected by columns 4. Multiple anti-permeability test modules are arranged vertically between the columns 4, and each anti-permeability test module is detachably connected to the column 4. Each anti-permeability test module is connected to a water pump. The water pump is connected to a control system. The control system controls the water pressure, thereby controlling the test pressure. Each anti-permeability test module can perform one set of anti-permeability tests. Multiple anti-permeability test modules can be used to perform multiple sets of anti-permeability tests at once, eliminating the need for a separate testing instrument, resulting in higher testing efficiency and less space occupation.

[0029] In some embodiments, such as Figures 1-4 As shown, the impermeability test module includes a mounting plate 5, on which multiple mold stands 6 are mounted. Mold sleeves 7 are bolted to the mold stands 6. A flow distribution system is located within the mounting plate 5 and is connected to the interior of the mold sleeves 7. The flow distribution system is also connected to a water pump. Water from the pump is injected into the mold inside the mold sleeves 7 via the flow distribution system for testing.

[0030] In some embodiments, such as Figures 1-4 As shown, fixed seats 8 are symmetrically arranged on the opposite sides of the two columns 4. Multiple fixed seats 8 are arranged vertically on each column 4, and a pin 9 is provided at the top of each fixed seat 8. Mounting sleeves 10 that cooperate with the pins 9 are provided on both sides of the mounting plate 5. After the test is completed, the anti-permeability test module is separated from the water pump. Then, the forks of a forklift are inserted into the anti-permeability test module to be removed. By operating the forklift, the mounting plate 5 is lifted, thereby separating the mounting sleeves 10 from the pins 9, thus removing the anti-permeability test module and facilitating the removal and placement of the mold inside the mold sleeve 7.

[0031] In some embodiments, such as Figures 1-4 As shown, a sealing gasket 11 is provided between the trial mold platform 6 and the trial mold sleeve 7 to prevent water leakage.

The main diversion pipe 12 is equipped with a high-pressure water pipe quick-connect fitting 13 for connection to a water pump. Multiple tee pipes 14 are connected to the main diversion pipe 12, the number of which is the same as the number of test mold stands 6. One end of each tee pipe 14 is connected to a switch 15, and the other end of each tee pipe 14 is connected to a diversion pipe, which is connected to a corresponding test mold stand 6. The water pressure diversion is controlled by the switch 15; the high-pressure water pipe quick-connect fitting 13 is used to control the diversion.

[0033] In some embodiments, such as Figures 1-4 As shown, an infusion tube 16 is fitted inside the sealing gasket 11 and the test mold platform 6. One end of the infusion tube 16 is connected to the inside of the test mold sleeve 7, and the other end of the infusion tube 16 is connected to a high-pressure pipe connector 17 that is connected to the shunt pipe. This allows the inside of the test mold sleeve 7 to be connected to the corresponding shunt pipe.

[0034] In some embodiments, such as Figures 1-4 As shown, each of the mounting plates 5 is provided with a drain pipe connected to the main diversion pipe 12, and each drain pipe is connected to the main drain pipe 18 provided on the column 4.

[0035] In some embodiments, such as Figures 1-4 As shown, the top of the mounting plate 5 is provided with a water receiving plate 19 to prevent excess liquid from overflowing.

[0036] In some embodiments, such as Figures 1-4 As shown, the test mold sleeve 7 is provided with an auxiliary handle 20 on the outside. This facilitates the removal of the test mold sleeve 7 from the test mold table 6.

[0037] In some other embodiments, such as Figure 1 As shown, the bottom of the mounting plate 5 is provided with a protective pad to prevent forklifts from damaging the impermeability test module.

[0038] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
