Description

Technical Field

[0001] This utility model relates to the field of underwater grouting experimental technology, specifically a water load simulation experimental device. Background Technology

[0002] Underwater grouting refers to an engineering technique that involves injecting grout into underwater foundations, structural gaps, or strata using specific materials and processes in underwater environments (such as rivers, oceans, and lakes) to achieve purposes such as reinforcement, seepage prevention, leak sealing, and connection.

[0003] In existing technologies, static water pressure tests on underwater grout specimens typically involve placing the specimen in a test water tank and pressurizing it to observe structural deformation or grout failure. Sealing the water tank requires flanges, gaskets, and multiple bolts, a cumbersome process. The tank's sealing performance is closely related to the installer's method and experience; improper operation can lead to insufficient sealing and leakage. Furthermore, in actual underwater use, the grout is subjected not only to high water pressure but also to its own weight and the weight of supporting structures (such as bridges), especially at the bottom. Simply conducting water pressure tests on the grout specimen cannot fully simulate its actual usage scenarios, resulting in inaccurate pressure test results. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a water load simulation experimental device. By installing a sliding, sealing upper cover plate on the lower water tank, the upper cover plate automatically seals the lower water tank after being moved onto it, reducing the need for manual installation and sealing. Furthermore, the greater the water pressure on the Y-shaped sealing ring between the lower water tank and the upper cover plate, the better the sealing effect, thus improving the airtightness between the two. Additionally, once the upper cover plate is sealed on the lower water tank, it can apply downward pressure to the grout specimen, simulating the pressure state of the grout in a real-world environment during water pressure testing. This improves the accuracy of the grout pressure test results and solves the problems mentioned in the background art.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a water load simulation experimental device, including a lower water tank for water pressure testing, and an upper cover plate that slides and seals the lower water tank. When the upper cover plate is sealed above the lower water tank, the upper cover plate can apply downward pressure to the grout specimen in the lower water tank.

[0007] Furthermore, a Y-shaped sealing ring is installed on the outside of the lower water tank, which can be connected and sealed with the upper cover plate.

[0008] Furthermore, an arc-shaped opening is provided on the inner bottom arc surface of the upper cover to reduce the initial contact friction between the upper cover and the Y-shaped sealing ring.

[0009] Furthermore, a threaded base is fixedly installed inside the lower water tank, and a support platform for supporting the grouting specimen is threadedly connected above the threaded base.

[0010] Furthermore, a pressure plate of the same size as the support is installed on the inner side of the top cover, aligned with the support platform.

[0011] Furthermore, the upper cover is driven to move up and down by a hydraulic cylinder. The pressure sensor is fixedly installed between the upper cover and the piston rod of the hydraulic cylinder, and the water pressure sensor is installed inside the lower water tank. The lower water tank is connected to the inlet pipe and the outlet pipe.

[0012] The beneficial effects of this utility model are as follows: By installing a sliding, sealing top cover on the lower water tank, the top cover can automatically seal the lower water tank after being moved onto it, thus reducing the manual installation and sealing process for workers. Furthermore, the greater the water pressure on the Y-shaped sealing ring between the lower water tank and the top cover, the better the sealing effect, thereby improving the airtightness between the lower water tank and the top cover. Additionally, after the top cover is sealed on the lower water tank, downward pressure can be applied to the grout specimen, simulating the pressure state of the grout in actual use during water pressure tests in the water tank, thereby improving the accuracy of the grout pressure test results.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figures 1-4 A water load simulation experimental device includes a lower water tank 1 for water pressure testing. An upper cover 2 is provided above the lower water tank 1 to slide and seal the lower water tank 1. When the upper cover 2 is sealed above the lower water tank 1, the upper cover 2 can apply downward pressure to the grout specimen in the lower water tank 1.

[0017] In this solution: the current water tank sealing method is cumbersome to operate and the sealing effect is unstable. When the grout is actually used in water, the grout will not only be subjected to strong water pressure, but also the grout, especially the bottom of the grout, will bear its own weight and the weight of the load (such as bridges). Simply conducting water pressure tests on the grout can not fully simulate the actual use scenario of the grout, affecting the accuracy of the pressure test results of the grout specimens. By installing a sliding and sealing upper cover plate 2 on the lower water tank 1, the upper cover plate 2 can automatically seal the lower water tank 1 after moving onto it. This reduces the manual installation and sealing process of the lower water tank 1. Furthermore, when the upper cover plate 2 is sealed on the lower water tank 1, it can also apply downward pressure to the grout specimen, simulating the pressure state of the grout in the actual use environment during the water pressure test in the water tank, thereby improving the accuracy of the pressure test results of the grout.

[0018] A Y-shaped sealing ring 3 is installed on the outside of the lower water tank 1, which can be connected and sealed with the upper cover plate 2.

[0019] In this embodiment: when the upper cover plate 2 moves down onto the lower water tank 1 and comes into full contact with the Y-shaped sealing ring 3, the inner wall of the upper cover plate 2 will adhere to the Y-shaped sealing ring 3. After water enters the lower water tank 1, the groove in the Y-shaped sealing ring 3 can fully expand and adhere tightly between the lower water tank 1 and the upper cover plate 2 under water pressure. The greater the water pressure on the Y-shaped sealing ring 3, the greater the adhesion pressure between it and the lower water tank 1 and the upper cover plate 2, thus the better the sealing effect, thereby improving the sealing performance between the lower water tank 1 and the upper cover plate 2 and reducing the phenomenon of leakage between the lower water tank 1 and the upper cover plate 2.

[0020] An arc-shaped opening is provided on the inner bottom arc surface of the upper cover plate 2 to reduce the initial contact friction between the upper cover plate 2 and the Y-shaped sealing ring 3.

[0021] In this embodiment: the arc-shaped opening on the upper cover plate 2 can first abut against the outer side of the Y-shaped sealing ring 3 as the upper cover plate 2 moves towards the lower water tank 1. As the upper cover plate 2 continues to move downward, the arc-shaped opening can guide the Y-shaped sealing ring to shift inward along the arc-shaped inner wall of the upper cover plate 2, so that the Y-shaped sealing ring 3 can stably abut against the upper cover plate 2, preventing the Y-shaped sealing ring 3 from being blocked between the protruding area on the outer side of the lower water tank 1 and the upper cover plate 2, thus preventing twisting and folding. This ensures that the inner wall of the upper cover plate 2 is smoothly connected and fitted with the Y-shaped sealing ring 3.

[0022] A threaded base 4 is fixedly installed inside the lower water tank 1, and a support platform 5 for supporting the grouting specimen is threadedly connected above the threaded base 4.

[0023] In this embodiment, the threaded base 4 can support the support platform 5, and the support platform 5 can be rotated on the threaded base 4 to adjust the support height up and down. It has good adaptability when supporting grout specimens of different heights, preventing the phenomenon that the upper cover plate 2 cannot be pressed on the grout specimen or cannot contact the Y-shaped sealing ring 3 after the upper cover plate 2 is pressed on the grout specimen, thus improving the applicability of the lower water tank 1 to the size of the grout specimen.

[0024] A pressure plate 6 of the same size as the support 5 is installed on the inner side of the upper cover plate 2, aligned with the support 5.

[0025] In this embodiment: the pressure plate 6 can work with the support platform 5 to press the grouting specimen, and press the grouting specimen tightly and provide downward pressure to the grouting specimen during the downward movement of the upper cover plate 2.

[0026] The upper cover plate 2 is driven to move up and down by the hydraulic cylinder 7. The pressure sensor 8 is fixedly installed between the upper cover plate 2 and the piston rod of the hydraulic cylinder 7. The water pressure sensor 9 is installed inside the lower water tank 1. The lower water tank 1 is connected to the inlet pipe 10 and the drain pipe 11.

[0027] In this embodiment: the hydraulic cylinder 7 can drive the upper cover plate 2 to move downward, so that the upper cover plate 2 can be moved and sealed above the lower water tank 1. The pressure sensor 8 can detect the pressure of the upper cover plate 2 and the pressure plate 6 on the grouting specimen. The water pressure sensor 9 can detect the pressure after water is injected into the lower water tank 1 and the upper cover plate 2. The water inlet pipe 10 and the water outlet pipe 11 can inject water into the lower water tank 1 and drain water respectively. After water is injected into the lower water tank 1, closing the valves on the water inlet pipe 10 and the water outlet pipe 11 can maintain the water pressure between the lower water tank 1 and the upper cover plate 2. The drive system of the hydraulic cylinder 7, the water pump of the water inlet pipe 10, and the valves connected to the water inlet pipe 10 and the water outlet pipe 11 are all controlled by an integrated control device. The display data of the pressure sensor 8 and the water pressure sensor 9 are also displayed through this control device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
