Technical Field

[0001] This utility model relates to the field of concrete, specifically to a high-performance concrete impermeability testing device. Background Technology

[0002] With the continuous development of construction engineering, high-performance concrete is widely used in various building structures due to its excellent mechanical properties and durability. However, the impermeability of concrete directly affects its durability and service life, making accurate testing of its impermeability particularly important.

[0003] Currently, the demand for permeability testing in the industry is increasing. In existing technologies, traditional testing methods usually involve using a pump to add a certain amount of water into the test container or maintaining a certain water pressure. After a set time, the permeability performance can be judged based on whether there is leakage in the concrete. Although this testing method can achieve the corresponding testing purpose, its testing method is relatively simple and cannot perform more comprehensive permeability testing on concrete test blocks. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-performance concrete impermeability testing device that uses an electric push rod to drive a pressure plate to adjust the test water pressure more flexibly and accurately, enabling a more comprehensive test of the concrete impermeability performance.

[0005] This utility model is achieved through the following technical solution: This utility model proposes a high-performance concrete impermeability testing device, including a testing box and a test block, wherein the test block is slidably connected inside the testing box, and a testing component is movably connected above the test block inside the testing box;

[0006] The test assembly includes a test cylinder and a pressure cylinder formed in the center of the test cylinder. An electric push rod is fixedly installed at the lower end of the inner top wall of the pressure cylinder. A pressure plate is fixedly connected to the movable end of the electric push rod. A water supply pipe and a water pressure sensor are respectively inserted into the upper two sides of the test cylinder. The water supply pipe is used to add test water into the test cylinder, and the water pressure sensor is used to detect changes in water pressure inside the test cylinder.

[0007] Furthermore, an electric telescopic rod is fixedly connected to the upper end of the test cylinder and to the periphery of the pressure cylinder. The fixed end of the electric telescopic rod is fixedly installed on the top wall of the test box, and the movable end of the electric telescopic rod is fixedly connected to the test cylinder. The electric telescopic rod is used to drive the test cylinder to perform vertical displacement movement.

[0008] Furthermore, a sealing ring is also fitted around the periphery of the pressure plate.

[0009] Furthermore, a sealing gasket is also fitted at the lower end of the test cylinder.

[0010] Furthermore, the water supply pipe is a telescopic pipe.

[0011] Furthermore, a sliding groove is provided in the test box at the connection of the test block, and a sliding platform is slidably connected in the sliding groove. The test block is placed on the sliding platform and slidably connected in the test box.

[0012] Furthermore, a control console is fixedly installed on the upper part of the testing box, and an observation window is installed on the door of the testing box via a slot.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention achieves flexible and precise adjustment of the water pressure within the test cylinder and pressure cylinder by installing a pressure plate inside the test cylinder and equipping it with an electric push rod for driving the pressure plate to adjust its displacement.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, a high-performance concrete impermeability testing device in this embodiment includes a testing box 1 and a test block 3. The test block 3 is slidably connected inside the testing box 1, and a testing component is movably connected above the test block 3 inside the testing box 1.

[0024] The test assembly includes a test cylinder 4 and a pressure cylinder 401 formed in the center of the test cylinder 4. An electric push rod 402 is fixedly installed at the lower end of the inner top wall of the pressure cylinder 401. A pressure plate 403 is fixedly connected to the movable end of the electric push rod 402. A water supply pipe 6 and a water pressure sensor 7 are respectively inserted into the upper two sides of the test cylinder 4. The water supply pipe 6 is used to add test water into the test cylinder 4, and the water pressure sensor 7 is used to detect the water pressure change inside the test cylinder 4.

[0025] This application provides a high-performance concrete permeability testing device that uses an electric actuator 402 to drive a pressure plate 403 to more flexibly and precisely adjust the test water pressure, enabling a more comprehensive test of the concrete's permeability resistance. This solves the problem of traditional testing methods that typically involve pumping a certain amount of water into a test container or maintaining a certain water pressure, and then judging the permeability resistance based on the presence of seepage after a set time. While this method achieves the desired testing objective, it is relatively limited and cannot perform more comprehensive permeability tests on concrete test blocks. The overall approach to solving this problem is to install a pressure plate 403 inside the test cylinder 4 and the pressure cylinder 401, and configure an electric actuator 402 for driving it. The pressure plate 403 is displaced to achieve flexible and precise adjustment of the water pressure in the test cylinder 4 and the pressure cylinder 401. During the test, the vertical displacement of the pressure plate 403 will directly affect the water pressure in the test cylinder 4 and the pressure cylinder 401, and the range of this effect can be precisely adjusted under the telescopic control of the electric push rod 402. Therefore, the testing device can perform more precise testing on the concrete test block 3. In addition, the pressure plate 403 can be controlled to increase the water pressure at an appropriate time and decrease the water pressure after an appropriate time according to actual needs, so as to achieve a more comprehensive testing effect on the concrete test block 3. Based on the above operation steps, the pressure plate 403 can also be controlled to continuously increase the water pressure at a certain speed and gradually decrease it after the pressure reaches the set value, thereby achieving a linear testing effect.

[0026] As one implementation method, such as Figure 2 and Figure 4 As shown, an electric telescopic rod 5 is fixedly connected to the upper end of the test cylinder 4 and the periphery of the pressure cylinder 401. The fixed end of the electric telescopic rod 5 is fixedly installed on the top wall of the test box 1, and the movable end of the electric telescopic rod 5 is fixedly connected to the test cylinder 4. The electric telescopic rod 5 is used to drive the test cylinder 4 to perform vertical displacement. The test cylinder 4 can be adjusted up and down under the drive of the electric telescopic rod 5. When the staff needs to put the concrete test block 3 into the test box 1, the electric telescopic rod 5 can be controlled to retract, so that it drives the test cylinder 4 to move upward, so that the staff can put the concrete test block 3 into the test box 1. After the staff has placed it, the electric telescopic rod 5 drives the test cylinder 4 to move downward and abut against the concrete test block 3. Then, the water supply pipe 6 adds test water into the test cylinder 4. At the same time, the water pressure sensor 7 can detect the water pressure change in the test cylinder 4.

[0027] As one implementation method, such as Figure 5As shown, a sealing ring 404 is also fitted around the pressure plate 403; the sealing ring 404 is used to improve the sealing and water-blocking effect between the pressure plate 403 and the inner wall of the pressure cylinder 401, and at the same time improve the stability of the pressure plate 403 in hydraulic pressure regulation.

[0028] As one implementation method, such as Figure 2 , Figure 4 and Figure 5 As shown, a sealing gasket 405 is also fitted at the lower end of the test cylinder 4; the sealing gasket 405 is used to improve the sealing performance of the test cylinder 4 against the test block 3 and prevent water leakage inside.

[0029] As one implementation method, such as Figure 2 and Figure 5 As shown, the water supply pipe 6 is a telescopic pipe; the telescopic effect of the water supply pipe 6 can adapt to the vertical displacement effect of the test cylinder 4, ensuring the stable water supply effect of the water supply pipe 6.

[0030] As one implementation method, such as Figure 3 As shown, a sliding groove 101 is provided at the connection point of the test block 3 inside the test box 1, and a sliding platform 102 is slidably connected in the sliding groove 101. The test block 3 is placed on the sliding platform 102 and slidably connected to the test box 1. The sliding platform 102 can assist the staff in placing the test block 3. For example, when placing the test block 3, the staff first places two corners of the test block 3 on the inner sliding platform 102, and then holds the other two corners of the test block 3. By using the sliding connection effect of the sliding platform 102, the test block 3 can be smoothly slid into the test box 1, and its outer two corners are placed on the outer sliding platform 102 to achieve the horizontal placement effect of the test block 3.

[0031] As one implementation method, such as Figure 1 As shown, a control console 2 is also fixedly installed on the upper end of the detection box 1. An observation window is installed on the door of the detection box 1 through a slot. The control console 2 is a PLC controller or control computer, which can control the extension and retraction of the electric telescopic rod 5 and the electric push rod 402, and can also receive real-time detection data from the water pressure sensor 7.
