Technical Field

[0001] This utility model relates to the technical field of permeable concrete, and in particular to a device for testing the permeability performance of permeable concrete. Background Technology

[0002] Permeable concrete is a new type of building material with unique pore structure and functional properties. Its porosity is typically 15%-25%, and its permeability is much higher than that of traditional drainage systems. This characteristic enables it to effectively intercept natural rainfall, replenish groundwater, and reduce urban runoff and the risk of flooding.

[0003] Currently, there is a lack of corresponding testing equipment for the permeability efficiency of permeable concrete. Therefore, this utility model proposes a permeability performance testing device for permeable concrete that is different from the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0004] To address the aforementioned problem of the lack of corresponding testing equipment for the permeability efficiency of permeable concrete, this utility model provides a permeable concrete permeability performance testing device.

[0005] This utility model provides a device for testing the permeability performance of permeable concrete, which adopts the following technical solution: A permeable concrete permeability performance testing device includes a horizontal plate, a test frame installed on the upper surface of the horizontal plate, a first test unit installed at the middle position of the top of the test frame, water injection units installed on both sides of the top of the test frame, multiple sets of support legs installed on the upper surface of the horizontal plate, and a second test unit that cooperates with the first test unit installed at the top of the multiple sets of support legs. A permeable concrete slab is provided inside the second test unit, and a measuring cylinder is provided on the upper surface of the horizontal plate. The permeable concrete slab can be stably placed through the first and second test units, and the permeability of the permeable concrete slab is tested through the water injection unit and the measuring cylinder.

[0006] By adopting the above technical solution, the permeable concrete slab is placed in the second test unit, the first test unit is started, and clean water is injected into the first test unit using the water injection unit, so that the clean water can seep out through the pores inside the permeable concrete slab, thereby detecting whether the permeability performance meets the requirements.

[0007] Optionally, the first test unit includes a cylinder, which is fixed to the top wall of the test frame. The bottom end of the cylinder output end penetrates the top wall of the test frame and is equipped with multiple sets of connecting rods. The bottom ends of the multiple sets of connecting rods are equipped with a test inner frame, and the bottom end of the test inner frame is equipped with a rubber gasket.

[0008] Optionally, the second test unit includes a test frame, which is fixed to the top wall of the support leg. A collection hopper is installed at the bottom of the inner cavity of the test frame, and a collection pipe penetrating the bottom wall of the test frame is installed at the bottom of the collection hopper. Multiple sets of support components are evenly installed on the bottom wall of the inner cavity of the test frame.

[0009] Optionally, the lifting component includes a placement rod that passes through the collection hopper and is installed on the bottom wall of the inner cavity of the test frame, with a placement plate installed at the top of the placement rod that contacts the permeable concrete slab.

[0010] By adopting the above technical solution, the permeable concrete slab is placed on multiple placement plates, and the cylinder is activated to extend until the rubber gasket is tightly attached to the upper surface of the permeable concrete slab, which facilitates the testing of the permeability performance of the permeable concrete slab.

[0011] Optionally, the water injection unit includes a water storage frame, which is fixed to the top wall of the test frame. The top of the water storage frame is provided with a soft plug that can be inserted and removed, and the bottom of the water storage frame is equipped with a water injection pipe that penetrates the top wall of the test frame.

[0012] By adopting the above technical solution, opening the control valve on the water injection pipe allows clean water in the inner cavity of the water storage frame to be injected into the inner cavity of the test inner frame through the water injection pipe, so that the clean water can seep out through the pores inside the permeable concrete slab, thereby detecting whether the permeability performance meets the requirements.

[0013] Optionally, an electronic timer is installed at one end of the bottom wall of the test frame.

[0014] By adopting the above technical solution, the test duration is set under the action of an electronic timer, so that staff can test whether the water permeability meets the requirements under the specified test duration.

[0015] In summary, this utility model has at least one of the following beneficial effects: This invention uses a starting cylinder to tightly fit a rubber gasket onto a permeable concrete slab, allowing clean water to be injected into the inner test frame of the water storage frame. This enables the clean water to seep through the pores inside the permeable concrete slab and be collected in the inner cavity of a measuring cylinder. By observing and reading the liquid level inside the measuring cylinder, the permeability performance can be tested to determine if it meets the requirements. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0019] Example 1: This example provides a device for testing the permeability performance of permeable concrete, such as... Figure 1 and Figure 2 As shown, this invention can solve the problem of the lack of corresponding testing equipment for the permeability efficiency of permeable concrete. It includes a horizontal plate 7, on the upper surface of which a test frame 15 is installed. The longitudinal section of the test frame 15 is set as an inverted U-shape. A first test unit is installed at the middle position of the top of the test frame 15. The first test unit includes a cylinder 17, which is fixed to the top wall of the test frame 15. The bottom end of the output end of the cylinder 17 penetrates the top wall of the test frame 15 and is equipped with multiple sets of connecting rods 2. A test inner frame 3 is installed at the bottom of the multiple sets of connecting rods 2. Both the upper and lower ends of the test inner frame 3 are set as open. A rubber gasket 13 is installed at the bottom of the test inner frame 3.

[0020] Combination Figure 1 and Figure 2 In this embodiment of the present invention, water injection units are installed on both sides of the top of the test frame 15. The water injection unit includes a water storage frame 16, which is fixed on the top wall of the test frame 15. A soft plug 18 that can be inserted and removed is provided at the top of the water storage frame 16. A water injection pipe 1 that penetrates the top wall of the test frame 15 is installed at the bottom of the water storage frame 16. A control valve is installed on the outside of the water injection pipe 1. Multiple sets of support legs 6 are installed on the upper surface of the horizontal plate 7. A second test unit is installed at the top of the multiple sets of support legs 6. The second test unit includes a test outer frame 14, which is fixed on the top wall of the support legs 6. The upper surface of the test outer frame 14 is set to be open.

[0021] Combination Figure 1 and Figure 2In an embodiment of this utility model, a collection hopper 11 is installed at the bottom of the inner cavity of the test frame 14, and a collection pipe 10 penetrating the bottom wall of the test frame 14 is installed at the bottom of the collection hopper 11. Multiple sets of support members are evenly installed on the bottom wall of the inner cavity of the test frame 14. The support members include a placement rod 5, which penetrates the collection hopper 11 and is installed on the bottom wall of the inner cavity of the test frame 14. A placement plate 4 is installed at the top of the placement rod 5. The longitudinal section of the placement plate 4 is L-shaped. Permeable concrete slabs 12 are provided on the multiple sets of placement plates 4. A measuring cylinder 9 is provided on the upper surface of the horizontal plate 7. The measuring cylinder 9 is located directly below the collection pipe 10.

[0022] The cylinder 17 is extended until the rubber gasket 13 is tightly fitted to the upper surface of the permeable concrete slab 12. The control valve on the water injection pipe 1 is opened, allowing clean water to be injected into the inner cavity of the water storage frame 16 into the inner cavity of the test inner frame 3. This allows the clean water to seep through the pores inside the permeable concrete slab 12 and be collected into the inner cavity of the measuring cylinder 9 through the collection pipe 10 under the conduction of the collection hopper 11. This allows the staff to test whether the permeability performance meets the requirements under the specified test duration.

[0023] Combination Figure 1 and Figure 2 In this embodiment of the invention, an electronic timer 8 is installed at one end of the bottom wall of the test frame 14 to monitor the water permeability time. The test duration is set under the action of the electronic timer 8, allowing personnel to check whether the water permeability performance meets the requirements within the specified test duration.

[0024] Working principle: When using this permeable concrete permeability performance testing device, place the horizontal plate 7 stably in an appropriate position, then place the permeable concrete slab 12 on multiple placement plates 4, start the cylinder 17 to extend and drive the connecting rod 2, the inner test frame 3 and the rubber gasket 13 to move downwards synchronously until the rubber gasket 13 is tightly attached to the upper surface of the permeable concrete slab 12, then pull out the soft plug 18 and inject an appropriate amount of clean water into the inner cavity of the water storage frame 16.

[0025] Opening the control valve on the water injection pipe 1 allows clean water to be injected into the inner cavity of the test inner frame 3 through the water injection pipe 1. This allows the clean water to seep out through the pores inside the permeable concrete slab 12 and be collected into the inner cavity of the measuring cylinder 9 through the collecting pipe 10 under the conduction of the collecting hopper 11. The test duration is set under the action of the electronic timer 8, so that the staff only needs to observe and read the liquid level height inside the measuring cylinder 9 to compare and obtain the water permeability of the permeable concrete slab 12 under the specified test duration. This allows the staff to check whether the water permeability performance meets the requirements. After the test is completed, the clean water in the inner cavity of the measuring cylinder 9 is poured out and the permeable concrete slab 12 is replaced to repeat the test.
