Description

Technical Field

[0001] This utility model relates to the field of leak sealing demonstration technology, specifically to a portable pressurized leak sealing demonstration device. Background Technology

[0002] During long-term service, concrete structures in municipal, water conservancy, and industrial facilities (such as various inspection wells, pipes, water tanks, and underground structures) often experience water seepage, leakage, or even water inrush due to material aging, load changes, foundation settlement, or construction defects. This seriously affects structural safety, functionality, and the surrounding environment. Traditional repair methods often require shutdown, drainage of the medium, and large-scale excavation, which are costly and disrupt normal operations.

[0003] Pressurized leak sealing technology is a targeted method developed to solve this problem. Its core lies in the fact that it does not require stopping the leakage of the medium or reducing the internal pressure (such as water pressure). It directly seals the leak point or defect location with fast-curing materials (such as epoxy resin, polyurethane, cement-based grout, etc.) through injection, spraying, filling or built-in sealing systems to form an effective barrier. It has significant advantages such as fast construction, good economy and minimal interference with operation, and has become one of the key technologies for the maintenance and repair of modern concrete structures.

[0004] Leakage is a common defect in hydraulic concrete structures. It is generally classified into three types: point leakage, line leakage, and surface leakage. Point leakage refers to discontinuous and irregular leakage, mainly manifested as water seeping through holes. Line leakage refers to continuous or regularly occurring leakage, primarily manifested as leakage through cracks, and can be divided into expansion joints and non-expansion joints. Surface leakage refers to large-area dampness and slight seepage in the concrete, commonly known as "sweating."

[0005] Currently, there is a lack of display devices on the market that can clearly, quickly, and safely demonstrate the dynamic sealing process of pressurized leak-sealing materials in public environments such as exhibitions. Exhibition scenarios require intuitive and visual effects (such as transparent observation windows and dynamic leakage simulations) to attract audiences and clearly convey the advantages of leak-sealing materials.

[0006] Therefore, there is an urgent need to develop a lightweight, easy-to-operate, and highly visual display device to fill the technological gap in the field of exhibition promotion of sealing materials. Utility Model Content

This device can clearly, quickly, and safely demonstrate the dynamic sealing process of pressurized leak sealing materials at exhibitions, which is conducive to promoting the use of leak sealing materials.

[0008] This utility model is achieved through the following technical solution: This utility model provides a portable pressurized leak-stopping demonstration device, including a first pipe assembly, a second pipe assembly, a leak simulation pipe, and a water receiving tank. The first and second pipe assemblies are respectively connected to two interfaces of a right-angle tee joint.

[0030] Please refer to Figures 1 to 3 This application provides a portable pressurized leak-stopping demonstration device, comprising a first pipe assembly, a second pipe assembly, a leak simulation pipe 3, and a water receiving tank 4. The first and second pipe assemblies are respectively connected to two ports of a right-angle tee connector 5. The first pipe assembly provides water head pressure to the second pipe assembly. A pressure gauge 6 is provided on the other port of the right-angle tee connector 5. The leak simulation pipe 3 is connected to the end of the second pipe assembly. A leak simulation sample block is provided inside the leak simulation pipe 3. The leak simulation sample block includes a point leak sample block 31, a line leak sample block 32, and a surface leak sample block 33, which are used to simulate point leaks, line leaks, and surface leaks in concrete, respectively. The water receiving tank 4 is located below the outlet end of the leak simulation pipe 3 to receive the water seeping from the leak simulation sample block.

[0031] The aforementioned leakage simulation sample block is cast in concrete inside the leakage simulation pipe 3. During casting, a seal must be formed between the leakage simulation sample block and the inner wall of the leakage simulation pipe 3 to prevent leakage. This leakage simulation sample block is divided into three types: point leakage sample block 31, line leakage sample block 32, and surface leakage sample block 33, corresponding to three types of leakage simulation pipe 3. One end of the leakage simulation pipe 3 is detachably connected to the end of the second pipe assembly, allowing for the selection of a suitable leakage simulation pipe 3 to be connected to the end of the second pipe assembly according to the needs of the simulation experiment.

[0032] The leakage simulation pipe 3 is detachable, allowing for multiple demonstrations and showcasing different types of leakage. Specifically, the leakage simulation pipe 3 has an outer diameter of 110mm and a length of approximately 250mm. Inside, a section of concrete structure is poured to simulate leakage, with a concrete length of approximately 100mm (this can be adjusted according to actual conditions). Different pouring methods are used to simulate point, line, and surface leakage, which are common in engineering projects.

[0033] Before the leak-sealing operation is carried out, water from the first pipe assembly enters the second pipe assembly and provides water head pressure. The water pressure at the leak location is displayed by pressure gauge 6. Under this water head pressure, the water in the pipe leaks out from the prefabricated defect on the leakage simulation block of the leakage simulation pipe 3 into the water receiving tank 4, making the exhibition site clean and beautiful.

[0034] This application uses a first pipeline assembly, a second pipeline assembly, a leakage simulation pipe 3, and a water receiving tank 4. The first pipeline assembly provides water head pressure to the second pipeline assembly, and a pressure gauge 6 displays the water pressure at the leakage location. The leakage simulation pipe 3 is connected to the end of the second pipeline assembly and contains leakage simulation blocks, including three types: point leakage block 31, line leakage block 32, and surface leakage block 33. A water receiving tank 4 is located below the outlet of the leakage simulation pipe 3. This device has a simple structure, can be assembled and disassembled on-site, and is easy to transport. It can be used to clearly, quickly, and safely demonstrate the dynamic sealing process of pressurized leak-sealing materials at exhibitions, and can intuitively demonstrate the sealing effect of pressurized leak-sealing materials, which is more conducive to the promotion of leak-sealing materials.

[0035] According to some embodiments of this application, a seepage hole 311 is provided at the center of the point leakage sample block 31, and the seepage hole 311 penetrates both ends of the point leakage sample block 31. Preferably, the seepage hole 311 is a conical hole, and the diameter of the end communicating with the second pipe assembly is smaller than the diameter of the other end. For example, when pouring concrete, the conical head of the front end of a plastic dropper can be inserted into the middle of the concrete, and the plastic dropper can be removed after curing to simulate point leakage in concrete.

[0036] According to some embodiments of this application, a seepage joint 321 is provided at the center of the linear seepage sample block 32, and the seepage joint 321 extends through both ends of the linear seepage sample block 32. For example, when pouring concrete, a long strip of plastic sheet can be inserted into the middle of the concrete, and after it has solidified, the plastic sheet can be removed to simulate linear seepage in the concrete.

[0037] According to some embodiments of this application, the surface leakage sample block 33 is made of permeable concrete to simulate concrete surface leakage.

[0038] According to some embodiments of this application, the first pipe assembly includes PVC pipes 11 and PVC straight connectors 12. Multiple PVC pipes 11 are arranged vertically and connected in series via the PVC straight connectors 12 to form a whole. The lowest PVC pipe 11 is connected to a right-angle tee connector 5. Preferably, both the PVC pipes 11 and the PVC straight connectors 12 are transparent components, making them easier to display and observe.

[0039] Specifically, the first pipe assembly consists of several transparent PVC pipes 11, each 1m long, 50mm in outer diameter, and 3.5mm thick, connected by transparent PVC straight connectors 12 (the pipe dimensions are adjustable). The pipe length can also be adjusted according to the desired pressure resistance of the sealing material. Water is injected into the pipes during use. This method utilizes the vertical height of the first pipe assembly to provide water head pressure. The multi-section pipe assembly also facilitates the movement and transport of the device.

[0040] According to some embodiments of this application, the system also includes a frame 8 and supports 9. The frame 8 is disposed next to the first pipe assembly and is used to support the vertical first pipe assembly. Multiple supports 9 are provided for support on the underside of the second pipe assembly. The frame 8 and supports 9 can also be used as a display stand.

[0041] According to some embodiments of this application, the first pipe assembly includes a first vertical pipe 13 and a first horizontal pipe 14. One end of the first vertical pipe 13 is connected to a right-angle tee connector 5, and the other end is connected to one end of the first horizontal pipe 14 through a right-angle two-way connector 15. The other end of the first horizontal pipe 14 is connected to a booster pump 7 through a right-angle two-way connector 15. In this way, the booster pump 7 provides the water head pressure.

[0042] According to some embodiments of this application, the second pipe assembly includes a first short pipe 21, a ball valve 22, a second short pipe 23, and a reducer 24 connected in series. One end of the first short pipe 21 is connected to a right-angle tee connector 5, and the other end of the first short pipe 21 is connected to one end of the ball valve 22. The other end of the ball valve 22 is connected to the small end of the reducer 24, and one end of the leakage simulation pipe 3 is connected to the large end of the reducer 24.

[0043] The ball valve 22 described above can control whether the water flow in the first pipe assembly and the second pipe assembly is connected to the crack on the leakage simulation sample block in the leakage simulation pipe 3. The inner diameter of the small end of the reducing head 24 is 50mm and the inner diameter of the large end is 110mm, which can realize the transition connection from 50mm to 110mm.

[0044] This device is assembled on-site during use. It can provide water pressure using either a vertical pipe of a certain height or a pressure pump to simulate three types of concrete leakage. A leak-sealing demonstration can then be conducted. For example, the leak-sealing material can be applied to the seepage point on the simulated leakage block using a dual-pipe grouting gun or by smearing, allowing for a pressurized leak-sealing demonstration and enabling consumers to visually observe the leak-sealing effect.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
