Description

Technical Field

[0001] The utility model relates to an anti-seepage tester, in particular to a concrete anti-seepage tester, and belongs to the field of concrete anti-seepage detection equipment. Background Art

[0002] Concrete is a composite material made of gel material, aggregate and water in appropriate proportions, which is hardened after a certain period of time. It is the most widely used artificial civil construction material in the world. Nowadays, concrete plays an irreplaceable role in the construction industry. It is popular because of its high hardness, wide source of raw materials and low cost. Before making concrete, it needs to be made according to the proportion, and after making it, it needs to be tested to avoid substandard quality. Among them, concrete impermeability test is a more important and common test item. The so-called impermeability performance refers to the ability of materials used in buildings (such as concrete) to resist the penetration of water or other liquid media (light oil, heavy oil) under pressure. The concrete impermeability tester is suitable for the determination and experimental research of the impermeability of concrete and mortar. It can also be used for the determination of the air permeability and quality inspection of building materials. Therefore, people usually use concrete impermeability testers to test the concrete impermeability.

[0003] The existing anti-seepage instrument includes multiple test tubes, each of which includes a test tube base and a sealing sleeve detachably connected to the test tube base. When using the concrete anti-seepage tester for testing, the concrete block to be tested needs to be made into a truncated cone in advance, and the top diameter of the sample is smaller than the bottom diameter; then the concrete test block is installed in the test tube and tightly sealed. A water inlet is provided on the test tube base, and pressurized water is injected into the lower side of the concrete test block through the test tube base. A certain water seepage pressure is applied through the control system, and the pressure change is recorded. After a certain period of time, it is observed whether water will penetrate the upper side of the concrete test block to form data records, etc. According to the test results, the anti-seepage performance and water permeability of the concrete can be evaluated.

[0004] In the existing impermeability tester, the test tube base and sealing sleeve of each test tube are mostly fixed by 6-8 groups of bolts, and each tester includes multiple test tubes. This results in the staff needing to repeatedly twist and disassemble multiple groups of bolts on multiple test tubes during the disassembly and assembly process of the concrete test block when conducting the impermeability test of the concrete test block. The whole process is relatively cumbersome to operate, and it takes a long time, which is inconvenient for the staff to replace and use, and it is difficult to achieve a good use effect. In addition, the labor intensity is relatively large, which will also affect the test efficiency. Some existing technologies add a pressurizing mechanism to the impermeability tester to replace the multiple groups of bolts on the test tube to fasten the test tube base and the sealing sleeve, but it still retains some bolt assemblies, and the pressurizing mechanism not only increases the equipment cost, but also complicates the equipment structure, and interferes with the disassembly and assembly process of the concrete test block.

[0005] In addition, when the existing impermeability tester is used, the cured concrete sample needs to be pressed into the preheated sealing sleeve by a pressurizer (or a press, etc.) to make the bottom surface of the sample flush with the bottom surface of the sealing sleeve, which is inconvenient to use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Example 1

[0029] like Figure 1-Figure 5As shown: a concrete impermeability tester, including an impermeability tester body 1, a test platform 2 is arranged on the impermeability tester body 1, six groups of test tubes for loading concrete test blocks 3 to be tested are arranged on the test platform 2, all test tubes are arranged in two rows on the test platform 2, the test tubes include a base 4 and a sealing sleeve 5 detachably connected to the base 4, the base 4 is fixed on the test platform 2, a water inlet 6 is arranged on the base 4, pressurized water is injected into the lower side of the concrete test block 3 through the test tube base 4, a certain water seepage pressure is applied through the control system of the impermeability tester, and the pressure change is recorded, and after a certain period of time, it is observed whether water will penetrate the upper side of the concrete test block 3 to form data records, etc. According to the test results, the impermeability and water permeability of concrete can be evaluated. The above are all prior arts and will not be described in detail.

[0030] The concrete impermeability tester provided in this embodiment also includes a sealing interlayer 7; in this embodiment, the base 4 is threadedly connected with the sealing sleeve 5, which is convenient for quick disassembly and assembly of the test tube, saving a lot of time, and does not increase the complex external pressurization structure. A support ring 15 is arranged in the sealing sleeve 5, and the concrete test block 3 is placed from the upper end of the sealing sleeve 5 and finally placed on the support ring 15, and a gap is formed between the concrete test block 3 and the sealing sleeve 5, and the sealing interlayer 7 is screwed into the gap between the concrete test block 3 and the sealing sleeve 5 and tightly wraps the concrete test block 3, specifically, in the process of the sealing interlayer 7 being screwed in, the concrete test block 3 is continuously accommodated until the concrete test block 3 is completely wrapped by the sealing interlayer 7 (or the lower end of the sealing interlayer 7 is against the support ring 15, and the height of the sealing interlayer 7 is set equal to the height of the sealing sleeve 5 above the support ring 15), and the sealing interlayer 7 is threadedly connected with the sealing sleeve 5, the connection is tight, and it is convenient for the sealing interlayer 7 to be screwed in and the concrete test block 3 to be tightly wrapped.

[0031] Example 2

[0032] This embodiment further optimizes the connection structure between the base 4 and the sealing sleeve 5 on the basis of the embodiment 1, specifically:

[0033] The base 4 is provided with a water tank 8, the water inlet 6 is provided in the middle of the water tank 8, the inner wall of the water tank 8 is provided with an internal thread, the lower end of the sealing sleeve 5 is provided with a connecting portion 9, the outer surface of the connecting portion 9 is provided with an external thread, and the connecting portion 9 of the sealing sleeve 5 is inserted into the water tank 8 and threadedly connected with the water tank 8.

[0034] In this embodiment, a first sealing ring 10 is nested at the bottom of the water tank 8. The first sealing ring 10 is opposite to the connecting part 9. When the connecting part 9 is connected to the water tank 8, the connecting part 9 presses the first sealing ring 10 to increase the sealing performance of the connection between the base 4 and the sealing sleeve 5. The first sealing ring 10 forms a seal between the sealing sleeve 5 and the base 4, which can reduce the situation where the measured water seeps out from the gap between the sealing sleeve 5 and the base 4 and affects the measured data of the test piece's anti-permeability performance.

[0035] Example 3

[0036] This embodiment further optimizes the connection structure between the base 4 and the sealing sleeve 5 on the basis of the embodiment 2, specifically:

[0037] A ring-shaped extension plate 11 is further disposed outside the lower portion of the sealing sleeve 5 , and the extension plate 11 is in contact with the outer edge of the water tank 8 , making the structure more reliable.

[0038] Example 4

[0039] This embodiment further optimizes the structure of the sealing interlayer 7 and the sealing sleeve 5 on the basis of the embodiment 3, specifically:

[0040] The inner cavity of the sealing sleeve 5 is a cylindrical structure, and the concrete test block 3 is a truncated cone structure, and its maximum outer diameter is smaller than the inner diameter of the sealing sleeve 5, so that the sealing interlayer 7 can completely wrap the concrete test block 3; the outer shape of the sealing interlayer 7 is a straight cylinder structure of the same size as the inner cavity of the sealing sleeve 5, which is convenient for connection and setting of threads. The inner cavity of the sealing interlayer 7 is a truncated cone structure that fits the outer shape of the concrete test block 3, which is convenient for sealing.

[0041] Example 5

[0042] This embodiment further optimizes the structure of the sealing interlayer 7 and the sealing sleeve 5 on the basis of the embodiment 4, specifically:

[0043] The upper inner cavity of the sealing sleeve 5 is provided with an internal thread, and the upper outer portion of the sealing interlayer 7 is provided with an external thread. The upper end of the sealing sleeve 5 and the upper end of the sealing interlayer 7 are threadedly connected, that is, the two only form a tight threaded connection at the upper end, which is convenient for quick disassembly and assembly, while ensuring that the sealing interlayer 7 can be screwed in and tightened.

[0050] After the concrete test block 3 is placed in the sealing sleeve 5, the overall mass is relatively large, and it is not convenient to lift it and place it on the base 4 or remove it. Therefore, in this embodiment, a handle 14 is provided on the outer wall of the sealing sleeve 5 to facilitate lifting the sealing sleeve 5 and rotating the sealing sleeve 5 to connect it to the base 4 in place.

[0051] When using the utility model, the cured concrete test block 3 is placed in the sealing sleeve 5, and then the sealing sleeve 5 is installed on the base 4, and the order of the two can also be exchanged; after the sealing sleeve 5 and the base 4 are threaded and tightened, the sealing interlayer 7 is screwed in until its upper end is flush with the upper end of the sealing sleeve 5. At this time, the sealing interlayer 7 completely wraps the concrete test block 3, and then the test can be started; after the test is completed, the sealing interlayer 7 is screwed out, and a small hammer or other tool is used to knock down the concrete test block 3 inside it for the next step of use, and then the sealing sleeve 5 is removed, and the cleaning operation is carried out. After wiping dry, the sealing sleeve 5 and the sealing interlayer 7 are reset.
