Description

Technical Field

[0001] This application relates to the field of concrete impermeability testing technology, specifically to a device for testing concrete impermeability. Background Technology

[0002] The impermeability of concrete is one of the important indicators for measuring concrete quality, directly affecting the durability and safety of buildings. With the expansion of the scale and improvement of the quality of construction projects, the requirements for the impermeability of concrete are becoming increasingly stringent.

[0003] Currently, the testing of anti-permeability properties both domestically and internationally is mainly conducted using methods such as hydrostatic testing and electrical flux methods. While these methods can meet testing requirements to some extent, they still suffer from problems such as complex operation, low accuracy, and high equipment costs.

[0004] In recent years, with the continuous development of testing technology, new anti-permeability testing devices have gradually become a research hotspot, aiming to improve testing efficiency, reduce costs and simplify operating procedures. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a device for testing the impermeability of concrete, which optimizes the pressure loading and data acquisition process, improves testing accuracy, and simplifies the operation procedure.

[0006] To achieve the above objectives, this application provides the following technical solution: a device for testing the impermeability of concrete, comprising a frame, a testing component, an adjustment component, and a control component. The testing component includes a hydraulic cylinder, a storage tank, and a sealing cap. The bottom end of the storage tank is connected to a pressurization pipeline, and the bottom end of the pressurization pipeline passes through the sealing cap and extends below it. A high-precision flow meter is installed on the inner wall of the pressurization pipeline. A pressurization piston is fixedly connected to the output end of the hydraulic cylinder. The pressurization piston is slidably sleeved on the inner wall of the storage tank. A sealing cavity is formed inside the frame. A high-precision pressure sensor is installed on the inner wall of the sealing cavity. A rubber sealing sleeve is embedded in the inner wall of the sealing cavity, and a concrete test block is placed on the inner wall of the rubber sealing sleeve.

[0007] The above solution, through optimized design and modular structure, improves testing accuracy, simplifies operation procedures, reduces equipment manufacturing costs, and is more practical. During testing, the concrete sample can be placed in a rubber sealing sleeve and sealed inside the hydraulic cylinder with a sealing cap. Then, the hydraulic cylinder is activated, causing the pressure piston to push the liquid inside the reservoir through the pressure pipeline to the inside of the hydraulic cylinder. A high-precision pressure sensor can monitor the pressure changes inside the hydraulic cylinder in real time, and a high-precision flow meter records the liquid flow rate through the concrete sample. The data processor integrates the pressure and flow data and generates a permeability performance report, thus enabling convenient testing and making it more practical.

[0008] Furthermore, a connecting pile is fixedly connected to the bottom surface of the hydraulic cylinder, and the upper surface of the liquid storage cylinder is fixedly connected to the bottom surface of the connecting pile.

[0009] The above scheme enables a stable connection between the hydraulic cylinder and the reservoir via the connecting piles.

[0010] Furthermore, a liquid replenishment port is connected to one side of the liquid storage cylinder, and a one-way valve is installed on the pipe section of the liquid replenishment port.

[0011] The above scheme allows for convenient addition of test liquid to the storage tank via the provided replenishment port and check valve.

[0012] Furthermore, the upper surface of the sealing cover has two positioning holes, and the upper surface of the frame is fixedly connected to two positioning bolts. Each positioning bolt has a nut installed on its top, and the positioning bolt is adapted to the positioning hole.

[0013] The above solution, with its positioning holes, positioning bolts, and nuts, allows for easy installation and removal of the sealing cover from the upper surface of the frame, facilitating subsequent testing.

[0014] Furthermore, a sealing ring is installed on the bottom surface of the sealing cover, the sealing ring is adapted to the inner wall of the sealing cavity, and a control valve is installed on the section of the pressurized pipeline.

[0015] The above solution improves the sealing performance at the connection between the sealing cover and the frame by using a sealing ring, thereby optimizing the test results. The control valve allows for easy control of the flow of liquid inside the storage tank.

[0016] Furthermore, the adjustment assembly includes two brackets fixedly connected to the upper surface of the frame. Each bracket has a diagonal brace fixedly connected to its outer surface. A lead screw and a guide rod are respectively installed at the top of the two brackets. The bottom end of the lead screw is rotatably connected to the top end of the corresponding bracket, and the bottom end of the guide rod is fixedly connected to the top end of the corresponding bracket.

[0017] The above scheme improves the stability of the support structure by using diagonal braces, and facilitates the adjustment of other components by using lead screws.

[0018] Furthermore, a top plate is fixedly connected to the top end of the guide rod, the top end of the lead screw is rotatably sleeved on the inner wall of the top plate, a knob is fixedly connected to the rotating end of the lead screw, and two connecting plates are fixedly connected to the outer surface of the hydraulic cylinder. One of the two connecting plates is threadedly connected to the lead screw, and the other connecting plate is slidably sleeved on the guide rod.

[0019] With the above scheme, turning the knob will cause the lead screw to rotate. The rotation of the lead screw can cause the hydraulic cylinder to move up and down through the two connecting plates, thereby facilitating the adjustment of the position of the sealing cover. By adjusting the position of the sealing cover, it is convenient to test the impermeability of the concrete test block.

[0020] Furthermore, the control component includes a data processor and a control panel fixedly connected to the front of the rack. All electrical components inside the detection component are electrically connected to the data processor, and the data processor is electrically connected to the control panel.

[0021] The above scheme simplifies the control process by using the control components. The data processor and control panel work together to integrate pressure and flow data and generate a seepage resistance performance report.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This device for testing the impermeability of concrete improves testing accuracy, simplifies operation, and reduces manufacturing costs through optimized design and modular structure, making it more practical. During testing, a concrete sample is placed in a rubber-sealed sleeve, and a sealing cap creates a sealed space inside the hydraulic cylinder. The hydraulic cylinder is then activated, causing a pressure piston to push liquid from the reservoir through a pressurized pipeline into the cylinder. A high-precision pressure sensor monitors pressure changes in the cylinder in real time, and a high-precision flow meter records the liquid flow rate through the concrete sample. A data processor integrates the pressure and flow data to generate an impermeability report, enabling convenient testing and enhancing practicality. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a device for testing the impermeability of concrete includes a frame 1, a testing component 2, an adjustment component 3, and a control component 4. The testing component 2 includes a hydraulic cylinder 201, a liquid storage cylinder 202, and a sealing cap 203. A connecting pile 207 is fixedly connected to the bottom surface of the hydraulic cylinder 201, and the upper surface of the liquid storage cylinder 202 is fixedly connected to the bottom surface of the connecting pile 207. The connecting pile 207 enables a stable connection between the hydraulic cylinder 201 and the liquid storage cylinder 202. A pressurization pipeline 204 is connected to the bottom end of the liquid storage cylinder 202. The bottom end of the pressurization pipeline 204 passes through the sealing cap 203 and extends to the bottom of the sealing cap 203. Liquid in the liquid storage cylinder 202 can pass through the pressurization pipeline. 204 is used for conveying. One side of the liquid storage cylinder 202 is connected to a liquid replenishment port 208. A one-way valve 209 is installed on the pipe section of the liquid replenishment port 208. The liquid for testing can be easily added to the liquid storage cylinder 202 through the liquid replenishment port 208 and the one-way valve 209. Two positioning holes 210 are opened on the upper surface of the sealing cover 203. Two positioning bolts 211 are fixedly connected to the upper surface of the frame 1. A nut 212 is installed on the top of each positioning bolt 211. The positioning bolts 211 are adapted to the positioning holes 210. The positioning holes 210, positioning bolts 211 and nuts 212 enable the sealing cover 203 to be easily installed and removed from the upper surface of the frame 1, which facilitates subsequent testing.

[0033] Please see Figure 3 , Figure 4 and Figure 5 A high-precision flow meter 205 is installed on the inner wall of the pressurization pipeline 204. The high-precision flow meter 205 allows for real-time monitoring of the liquid flow rate, facilitating subsequent calculations of the impermeability. A pressurization piston 206 is fixedly connected to the output end of the hydraulic cylinder 201. The pressurization piston 206 is slidably sleeved on the inner wall of the liquid storage cylinder 202. When the hydraulic cylinder 201 is activated, it drives the pressurization piston 206 to move within the liquid storage cylinder 202, facilitating pressurization. A sealing cavity 213 is provided inside the frame 1. A high-precision pressure sensor 214 is installed on the inner wall of the sealing cavity 213. The high-precision pressure sensor 214 allows for real-time monitoring of the internal pressure of the hydraulic cylinder 201. A rubber sealing sleeve 215 is embedded in the inner wall of the sealing cavity 213. A concrete test block 216 is placed on the inner wall of the rubber sealing sleeve 215. The rubber sealing sleeve 215 ensures that the sides and bottom of the concrete test block 216 are completely sealed, with only the top exposed to liquid pressure. This ensures that the liquid can only penetrate through the pores and micro-cracks inside the concrete test block 216, rather than leaking from the gap between the concrete test block 216 and the hydraulic cylinder 201. This design is key to the concrete impermeability test, ensuring the accuracy and reliability of the test results. A sealing ring 217 is installed on the bottom surface of the sealing cover 203, which is adapted to the inner wall of the sealing cavity 213. A control valve 218 is installed on the section of the pressurized pipeline 204. The sealing ring 217 improves the sealing performance at the connection between the sealing cover 203 and the frame 1, thereby optimizing the test results. The control valve 218 allows for convenient control of the flow of liquid inside the liquid storage cylinder 202.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The adjustment assembly 3 includes two brackets 301 fixedly connected to the upper surface of the frame 1. Each bracket 301 has a diagonal brace 302 fixedly connected to its outer surface. The top of each bracket 301 is respectively equipped with a lead screw 303 and a guide rod 304. The bottom end of the lead screw 303 is rotatably connected to the top end of the corresponding bracket 301, and the bottom end of the guide rod 304 is fixedly connected to the top end of the corresponding bracket 301. The diagonal brace 302 can improve the stability of the bracket 301, and the lead screw 303 can facilitate the adjustment of other components. The top end of the guide rod 304 is fixedly connected to a top plate 305, and the top end of the lead screw 303 is rotatably sleeved on the inner wall of the top plate 305. The rotating end of the lead screw 303 is fixedly connected to a knob 306. The outer surface of the hydraulic cylinder 201 is fixedly connected to two connecting plates 307, and one of the connecting plates 307 is threadedly connected to the lead screw 303.

[0035] Please see Figure 1 , Figure 2 and Figure 3 One of the two connecting plates 307 is slidably sleeved on the guide rod 304. When the knob 306 is turned, the lead screw 303 will rotate. When the lead screw 303 rotates, the hydraulic cylinder 201 can move up and down through the two connecting plates 307, thereby facilitating the adjustment of the position of the sealing cover 203. By adjusting the position of the sealing cover 203, it is convenient to test the impermeability of the concrete test block 216. The control component 4 includes a data processor 401 and a control panel 402 fixedly connected to the front of the frame 1. The electrical components inside the detection component 2 are all electrically connected to the data processor 401. The data processor 401 is electrically connected to the control panel 402. The control component 4 simplifies the control process. The data processor 401 and the control panel 402 work together to integrate pressure and flow data and generate an impermeability report.

[0036] It should be noted that the concrete impermeability test is achieved by measuring the permeability of a liquid, usually water, through the concrete specimen 216 under pressure.

[0037] In this embodiment, a device for testing the impermeability of concrete improves testing accuracy, simplifies operation, and reduces equipment manufacturing costs through optimized design and modular structure, making it more practical. During testing, a concrete specimen 216 can be placed in a rubber sealing sleeve 215 and sealed inside a hydraulic cylinder 201 by a sealing cap 203. Then, the hydraulic cylinder 201 is activated, causing the pressure piston 206 to push the liquid inside the storage cylinder 202 through the pressure pipeline 204 to the inside of the hydraulic cylinder 201. A high-precision pressure sensor 214 monitors the pressure changes inside the hydraulic cylinder 201 in real time, and a high-precision flow meter 205 records the liquid flow rate through the concrete specimen 216. The data processor 401 integrates the pressure and flow data and generates an impermeability performance report, thus enabling convenient testing and making it more practical.

[0038] The working principle of the above embodiment is as follows: First, the concrete test block 216 is placed in the rubber sealing sleeve 215. Then, the knob 306 is turned to rotate the screw 303. When the screw 303 rotates, it can drive the hydraulic cylinder 201 to move downward through the connecting plate 307. When the hydraulic cylinder 201 moves downward, the sealing cover 203 can move downward and be inserted into the sealing cavity 213. At the same time, the two positioning bolts 211 will pass through the sealing cover 203 through the positioning holes 210 respectively. Then, the two nuts 212 are screwed onto the two positioning bolts 211 respectively to achieve the positioning effect of the sealing cover 203. Then, the hydraulic cylinder 201 is started. When 201 is started, it will drive the pressurizing piston 206 to pressurize the inside of the hydraulic cylinder 201. When the pressurizing piston 206 moves down, it can transport the liquid inside the liquid storage tank 202 to the hydraulic cylinder 201 through the pressurizing pipeline 204 to pressurize the inside of the hydraulic cylinder 201. The pressurizing pipeline 204 can monitor the pressure change inside the hydraulic cylinder 201 in real time. The high-precision flow meter 205 can record the liquid flow rate through the concrete test block 216 and then feed the data back to the data processor 401. The data processor 401 integrates the pressure and flow data and generates a seepage resistance performance report, which is displayed through the control panel 402.
