Description

Technical Field

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

[0002] Concrete is a composite material formed by binding fine and coarse aggregates with cement and allowing it to harden over a period of time. In the past, lime-based cement, such as lime paste, was the most common, but hydraulic cement, such as calcium aluminate cement or silicate cement, is sometimes used. Non-cement-based concrete is different from other concretes in that it directly binds various aggregates together. Non-cement-based concrete includes asphalt concrete, which uses asphalt as a binder, and polymer concrete, which uses polymers as a binder. Asphalt concrete is often used for road surfaces.

[0003] The applicant found a Chinese patent published under the title "A Concrete Permeability Testing Device" (CN219978084U). This patent mainly uses a first water pump to extract liquid from a water tank, which is then sprayed onto the surface of a concrete block through a water pipe, an outlet pipe, and a nozzle. Some of the liquid seeps through the concrete block into a collection box and then flows into a measuring cylinder. A filter plate prevents impurities from falling into the measuring cylinder. Excess liquid flows to the bottom of a working chamber, where a second water pump extracts the excess liquid and returns it to the water tank for reuse, saving resources and making the device convenient to use. The permeability can then be calculated by observing the liquid level inside the measuring cylinder. The aforementioned device, through a series of structural designs, can achieve the effects of fixing concrete test blocks and recovering excess liquid. However, in actual use, the concrete test block is placed on a sealing gasket, but the concrete test block and the sealing gasket cannot be exactly the same size. This results in a gap between the concrete test block and the liquid collection box. Therefore, during permeability testing, liquid can easily enter the interior of the liquid collection box through the gap between the concrete test block and the liquid collection box, leading to inaccurate results when testing the permeability of the concrete test block.

[0024] This utility model provides, for example Figure 1-5 The illustrated concrete permeability testing device includes a main body 1 and support legs 11 fixedly connected to the four corners of the bottom surface of the main body 1. A placement cylinder 7 is fixedly connected to the bottom surface of the inner wall of the main body 1, and a measuring cylinder 8 is fixedly connected to the bottom surface of the placement cylinder 7. The bottom surface of the measuring cylinder 8 penetrates the bottom surface of the inner wall of the main body 1 and extends to the bottom surface of the main body 1. The interior of the main body 1 is equipped with a water delivery component 2 for delivering water to the surface of the concrete test block. The interior of the main body 1 is also equipped with a pushing component 4 that can move downwards or upwards. The interior of the main body 1 is equipped with a mechanism that, under the urging of the pushing component 4, seals the gap between the concrete test block and the placement cylinder 7 and... The sealing component 3, which fixes the concrete test block, places the concrete test block inside the placement cylinder 7. Then, the pushing component 4 causes the sealing component 3 to move downward to press and fix the top of the concrete test block, while simultaneously sealing the gap between the concrete test block and the placement cylinder 7. Water is then delivered to the surface of the concrete test block through the water delivery component 2 to test the water permeability of the concrete test block. This device avoids the problem of low accuracy of test results caused by the gap between the concrete test block and the placement cylinder 7, thus ensuring the stability of the test results of the concrete test block.

[0025] like Figure 5As shown, the pushing component 4 includes a mounting plate 401, the top surface of which is fixedly connected to the top surface of the inner wall of the body 1. The pushing component 4 also includes a hydraulic rod 402, the top end of which is fixedly connected to the bottom surface of the mounting plate 401. The output end of the hydraulic rod 402 is fixedly connected to a pushing plate 403, which can move upward or downward as the hydraulic rod 402 is activated.

[0026] like Figure 2 and Figure 3 As shown, the water delivery assembly 2 includes a water pump 201, the bottom surface of which is fixedly connected to the top surface of the main body 1. A first connecting pipe 202 is fixedly connected to the outlet end of the water pump 201.

The water delivery assembly 2 also includes a flexible hose 203, the top end of which is fixedly connected to the bottom end of the first connecting pipe 202. A second connecting pipe 204 is fixedly connected to the bottom end of the flexible hose 203. The bottom end of the second connecting pipe 204 penetrates the top surface of the push plate 403 and extends into the push plate 403. The bottom surface of the water delivery assembly 2 also includes a water distribution plate 205, which can deliver water into the interior of multiple nozzles 206. The top surface of the water distribution plate 205 is fixedly connected to the bottom surface of the push plate 403, and the top surface of the water distribution plate 205 is fixedly connected to the bottom end of the second connecting pipe 204. The interior of the water distribution plate 205 is connected to the interior of the second connecting pipe 204. Multiple nozzles 206 are fixedly connected to the bottom surface of the water distribution plate 205. The multiple nozzles 206 can deliver water evenly to the surface of the concrete test block. All of the multiple nozzles 206 are connected to the interior of the water distribution plate 205.

[0027] like Figure 3 and Figure 5 As shown, the sealing assembly 3 includes two sliding rods 301. The walls of the two sliding rods 301 are slidably connected to the inner wall of the push plate 403. The top of each of the two sliding rods 301 is fixedly connected to a baffle 302. A spring 303 is sleeved on the wall of each of the two sliding rods 301. The spring 303 enables the first sealing ring 304 to fit tightly against the top surface of the concrete test block. The sealing assembly 3 also includes a first sealing ring 304. The first sealing ring 304 can fit tightly against the inner wall of the placement cylinder 7 and the top surface of the concrete test block, thereby preventing water seepage between the concrete test block and the placement cylinder 7. The top surface of the first sealing ring 304 is fixedly connected to the top of the two sliding rods 301. The outer diameter of the first sealing ring 304 is the same as the inner diameter of the placement cylinder 7.

[0028] like Figure 4As shown, an installation ring 15 is fixedly connected to the inner wall of the placement cylinder 7. A filter screen 16 is placed on the top surface of the installation ring 15. A second sealing ring 18 is fixedly connected to the top surface of the filter screen 16. The second sealing ring 18 and the inner wall of the installation ring 15 are threaded together with multiple fastening studs 17.

[0029] like Figure 1 and Figure 2 As shown, a water tank 5 is fixedly connected to the top surface of the main body 1, and a water inlet pipe 6 is fixedly connected to the top surface of the water tank 5.

The timer 12 is set to facilitate the calculation of water permeability later. A drain valve 9 is fixedly connected to the bottom surface of the measuring cylinder 8. The drain valve 9 can drain the water inside the measuring cylinder 8.

[0030] The working principle of this utility model is as follows: When using the device, first open the box door 13, then place the concrete test block directly inside the placement cylinder 7, then close the box door 13 and the drain valve 9, then start the hydraulic rod 402. After the hydraulic rod 402 is started, it pushes the push plate 403 downward. As the push plate 403 moves, the two sliding rods 301 drive the first sealing ring 304 to contact the top surface of the concrete test block. Since the outer diameter of the first sealing ring 304 is the same as the inner diameter of the placement cylinder 7, the first sealing ring 304 can fit tightly with the placement cylinder 7. Then, as the push plate 403 continues to move, the two sliding rods 301 move upward and actuate the spring 303 on the rod wall. The compression causes the two springs 303 to push the first sealing ring 304 downwards, ensuring that the first sealing ring 304 is tightly attached to the top surface of the concrete test block. Then, by starting the timer 12 and the water pump 201, the water pump 201 draws water from the water tank 5 and delivers it to the surface of the concrete test block through the hose 203, the water distribution plate 205, and the nozzle 206. The water then seeps through the concrete test block and eventually enters the measuring cylinder 8. The permeability of the concrete test block is calculated by observing the value of the measuring cylinder 8 and the time taken, and then by using a calculation formula. After the test is completed, the water inside the measuring cylinder 8 is drained by opening the drain valve 9. The original text highlights the innovative structure and does not elaborate on the existing technology.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
