Technical Field
[0001] This utility model relates to the field of leakage testing technology for waterproof materials in high-water-level basements, specifically a leakage testing device for waterproof materials in high-water-level basements. Background Technology
[0002] When the basement of this project is in a high water level state, the surrounding walls and upper and lower walls of the basement will be affected by groundwater pressure. Therefore, in order to ensure the quality of the project, reasonable and effective waterproofing construction techniques must be adopted. Due to the project's location by the sea, the groundwater is relatively abundant, and there are a large number of weak silty soil layers, which is a typical coastal high water level area. This poses many difficulties for the normal construction of the underground structure, especially the waterproofing work. Through a combination of theoretical analysis and on-site construction, this paper studies the construction process, construction technology and key operation points of the waterproofing technology for the underground structure of the project. It also analyzes the difficulties in waterproofing the underground structure in coastal high water level areas and proposes corresponding treatment measures to provide a reference for waterproofing problems in similar projects.
[0003] To ensure the proper functioning of basements with high water levels, it is necessary to test the seepage resistance of construction materials. Existing basement waterproofing material leakage testing devices mostly simulate high water level environments (such as fixed water level or constant pressure) using static water pressure. However, the actual hydrological environment of basements is often accompanied by dynamic changes (such as periodic fluctuations in groundwater level, instantaneous water pressure impact, and water erosion). For example, rainy seasons or construction in the surrounding area may cause the water level to rise rapidly, and traditional devices cannot simulate the impact of such dynamic water pressure changes on waterproofing materials, leading to deviations between test results and actual seepage resistance. Existing basement waterproofing material leakage testing devices generally rely on manual observation of seepage results. Although this can detect seepage phenomena in a timely manner, it cannot quickly pinpoint the exact location of the seepage, which is not convenient for subsequent analysis of seepage results. Therefore, to address the above problems, a new high water level basement waterproofing material leakage testing device is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a leakage test device for waterproof materials in high-water-level basements, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A leakage test device for waterproofing materials in high-water-level basements includes a leakage test chamber. The inner side of the leakage test chamber has a water passage hole, and the interior of the leakage test chamber has a water passage groove. Symmetrically arranged pressure sensors are fixedly connected to the inner side of the water passage groove. Electromagnetic valves are connected to both sides of the leakage test chamber. Variable frequency centrifugal water pumps are connected to the front and rear sides of the leakage test chamber. A sealing groove is formed at the top of the leakage test chamber, and a sealing ring is provided inside the sealing groove. A fixing ring is fixedly connected to the top of the sealing ring. A waterproofing material-coated concrete substrate located inside the leakage test chamber is fixedly connected to the inner side of the fixing ring. An operating rod located at the bottom is fixedly connected to the inner side of the waterproofing material-coated concrete substrate. A supporting square tube is provided inside the waterproofing material-coated concrete substrate, with an installation groove at the top of the supporting square tube, an observation groove on the inner side of the supporting square tube, and a connecting groove on the outer side of the supporting square tube.
[0007] Preferably, there are four mounting slots, which are arranged symmetrically in front and behind inside the four sides of the supporting square tube.
[0008] Preferably, there are several observation slots, which are evenly arranged in a matrix on the inner side of the supporting square tube.
[0009] Preferably, there are four connecting grooves, which are symmetrically arranged on the four sides of the surface of the supporting square tube.
[0010] Preferably, the inner shape of the sealing groove matches the shape of the sealing ring, both being open-shaped, and the inner dimensions of the sealing groove match the dimensions of the sealing ring.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, the leakage test chamber, water passage holes, water passage groove, pressure sensor, solenoid valve, variable frequency centrifugal water pump, sealing groove, sealing ring, fixing ring, and waterproof material coated concrete substrate are included. The pressure sensor and variable frequency centrifugal water pump work together to accurately adjust the appropriate test water pressure. The intermittently operating solenoid valve automatically releases water, and the variable frequency centrifugal water pump automatically adjusts the water level. Multiple water passage holes simulate water flow impact, ultimately achieving dynamic water flow detection, thus solving the problem of... To ensure the normal use of basements with high water levels, it is necessary to test the seepage prevention performance of construction materials. Existing basement waterproofing material seepage testing devices mostly simulate high water level environments (such as fixed water level or constant pressure) with static water pressure. However, the actual hydrological environment of basements is often accompanied by dynamic changes (such as periodic fluctuations in groundwater level, instantaneous water pressure impact, water flow scouring, etc.). For example, the rainy season or construction in the surrounding area may cause the water level to rise rapidly. Traditional devices are difficult to simulate the impact of such dynamic water pressure changes on waterproofing materials, resulting in deviations between test results and actual seepage prevention performance.
[0013] 2. In this utility model, by setting up supporting square tubes, installation grooves, observation grooves, and connecting grooves, and by installing the seepage detection plate through the installation groove, the seepage of the waterproof material coated concrete substrate can be detected. The matrix arrangement of the observation grooves allows for accurate observation of the color change of the seepage detection plate at the corresponding position, and facilitates quick positioning of the telescopic coordinates. This solves the problem that existing basement waterproof material leakage test devices generally rely on manual observation of seepage results. Although seepage can be detected in time, it cannot quickly pinpoint the exact location of the seepage, which is not convenient for subsequent analysis of the seepage results.

[0021] Please see Figure 1-3 This utility model provides a technical solution:
[0022] A high-water-level basement waterproofing material leakage test device includes a leakage test chamber 1, a water passage hole 2 on the inner side of the leakage test chamber 1, a water passage groove 3 inside the leakage test chamber 1, pressure sensors 4 symmetrically arranged fixedly connected to the inner side of the water passage groove 3, solenoid valves 5 connected to both sides of the leakage test chamber 1, variable frequency centrifugal water pumps 6 connected to the front and rear sides of the leakage test chamber 1, a sealing groove 7 at the top of the leakage test chamber 1, a sealing ring 8 inside the sealing groove 7, a fixing ring 9 fixedly connected to the top of the sealing ring 8, a waterproofing material coated concrete substrate 10 located inside the leakage test chamber 1 fixedly connected to the inner side of the fixing ring 9, an operating rod 11 located at the bottom fixedly connected to the inner side of the waterproofing material coated concrete substrate 10, a supporting square tube 12 inside the waterproofing material coated concrete substrate 10, an installation groove 13 at the top of the supporting square tube 12, an observation groove 14 inside the supporting square tube 12, and a connecting groove 15 outside the supporting square tube 12.
[0023] There are four mounting slots 13, which are symmetrically arranged inside the four sides of the supporting square tube 12. The four mounting slots 13 can be used to install the seepage detection plates in four directions inside the supporting square tube 12. There are several observation slots 14, which are evenly arranged in a matrix on the inner side of the supporting square tube 12. The multiple sets of observation slots 14 can achieve the effect of quickly locating the coordinates of the seepage point. There are four connecting slots 15, which are symmetrically arranged in four directions on the surface of the supporting square tube 12. The connecting slots 15 can be used to detect multiple directions inside the waterproof material coated concrete substrate 10. The inner shape of the sealing slot 7 matches the shape of the sealing ring 8, both being open. The inner dimensions of the sealing slot 7 match the dimensions of the sealing ring 8, achieving a sealing effect between the waterproof material coated concrete substrate 10 and the leakage test box 1, thereby ensuring accurate pressure.
[0024] Workflow: When a high-water-level basement waterproofing material leakage test device is needed, the entire device is powered externally. First, the adjusted concrete is poured into the required shape, and a fixing ring 9 with a sealing ring 8 is embedded on the outside of the concrete. An operating rod 11 is embedded inside. After drying, a waterproof coating is applied. Then, the external machinery is operated to lift the waterproof material-coated concrete substrate 10 through the operating rod 11 and place it into the inside of the leakage test chamber 1. When fully connected, the sealing ring 8 below the fixing ring 9 will engage with the sealing groove 7, achieving a sealing effect. Then, water is injected into the water channel 3 through the variable frequency centrifugal water pump 6, and the water comes into contact with the waterproof material-coated concrete substrate 10 through the water passage hole 2. The water will produce a leakage at the moment it passes through the water passage hole 2. The system generates a certain impact force to simulate the impact of underground water flow. The internal pressure sensor 4 detects the pressure and controls the variable frequency centrifugal water pump 6 to adjust its speed to achieve a water pressure of 1.65 to 4.52 meters underground. Once the specified pressure is reached, the variable frequency centrifugal water pump 6 stops working. The solenoid valve 5 will open periodically according to the set program to discharge the water source in the water passage 3. Through the linkage of the pressure sensor 4, solenoid valve 5, and variable frequency centrifugal water pump 6, the process of simulating the rise and fall of water flow is realized. The seepage detection plate in the installation slot 13 detects the inside of the waterproof material coated concrete substrate 10. When seepage occurs, the seepage detection plate at the corresponding position will change color, which is convenient for the experimenters to observe and judge. The matrix-set observation slots 14 can quickly locate the coordinates of the current seepage position.
