Description

Technical Field

[0001] The utility model belongs to the technical field of plugging and draining, and in particular relates to a plugging and draining device for water conservancy project management. Background Art

[0002] Leakage plugging and drainage devices play a vital role in reservoir management, especially when dealing with water flow problems caused by underground caves. In the rainy season, groundwater rushes from deep in the strata to the reservoir, adding a valuable source of water storage to the reservoir. However, in the dry season, when the groundwater level drops, the water in the reservoir will be lost through the groundwater inlets and outlets, which poses a serious challenge to the reservoir's water storage capacity and the effective use of water.

[0003] In order to effectively meet this challenge, plugging and drainage devices are widely used in reservoir management to achieve precise control of water flow. However, the currently commonly used installation method of pre-casting the foundation with cement and fixing it with bolts has exposed obvious limitations in practical applications. When the leak opening is large or the water flow rate is high, it is difficult for cement to stay at the leak or form an effective plug, making it difficult to cast the foundation smoothly. In addition, the continuous outflow of water will also interfere with the solidification process of cement, resulting in insufficient overall strength of the solidified cement, which is difficult to meet the basic strength requirements of the project.

[0004] Therefore, it is very necessary to invent a leak-stopping and drainage device for water conservancy project management. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a plugging and drainage device for water conservancy project management, comprising a drainage and dredging pipe seat, a plugging and expansion seat and a controllable valve, the plugging and expansion seat and the controllable valve are fixedly installed on the drainage and dredging pipe seat, and the controllable valve is connected to the drainage and dredging pipe seat and is used to control the discharge of liquid inside the drainage and dredging pipe seat;

[0006] The drainage dredging pipe seat comprises a drainage pipe seat, a drainage pipe port, a flange, a pipe seat, an attachment pattern, bolts and a plugging cover; a cement air bag of the plugging expansion seat is fixedly mounted on the drainage pipe seat; the drainage pipe port and the flange are integrally arranged on the drainage pipe seat, and the drainage pipe port is fixedly connected to the controllable valve; the attachment pattern is arranged on the outer surface of the drainage pipe seat; the flange integrally arranged on the drainage pipe seat is fixedly connected to the plugging cover through the bolts; the pipe seat integrally arranged on the flange is fixed to the grouting pipe of the plugging expansion seat;

[0007] The plugging expansion seat includes a cement airbag, air leakage holes and a grouting pipe. The air leakage holes are arranged in an array on one side of the cement airbag. The cement airbag is connected to one end of the grouting pipe, and the other end of the grouting pipe is fixed to the pipe seat.

[0008] Preferably, the attachment pattern integrally provided on the drainage tube seat is a spiral protrusion and is respectively provided on the outer surface of the drainage tube seat, and the attachment pattern is located on one side of the cement airbag.

[0009] Preferably, the drainage pipe opening is located on one side of the flange and the sealing cover, and a sealing rubber column is provided on the inner surface of the sealing cover, which is in interference contact with the inner wall of the drainage tube seat.

[0010] Preferably, the pipe seat is an inverted "U" base, and a fixing hole is provided on the pipe seat to allow the grouting pipe to pass through, and the grouting pipe is located above the drainage pipe seat.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model has achieved a significant breakthrough in the field of water conservancy project management. It abandons the traditional technology of relying on precast foundations for fixation, and innovatively introduces an expansion-type plugging and sealing mechanism. This mechanism injects cement slurry into a specially designed airbag, causing the airbag to expand rapidly and fit tightly to the leak, thereby achieving efficient plugging. At the same time, the expanded airbag can also effectively protect the cement inside to prevent it from being washed away by high-speed water flow, ensuring the durability and reliability of the plugging effect. More importantly, the design minimizes direct contact between the internal cement and the external leaking water flow, effectively reducing the weakening of the cement due to water flow scouring, thereby ensuring the overall strength of the cement after subsequent solidification. This innovation not only meets the basic needs of the project for the plugging effect, but also greatly improves the applicability and flexibility of the device, enabling it to cope with leaks of various shapes and sizes, providing a strong guarantee for the safe and stable operation of water conservancy projects.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a plugging and drainage device for water conservancy project management, comprising a drainage and dredging pipe seat 1, a plugging and expansion seat 2 and a controllable valve 3. The plugging and expansion seat 2 and the controllable valve 3 are fixedly installed on the drainage and dredging pipe seat 1. The controllable valve 3 is connected to the drainage and dredging pipe seat 1 and is used to control the discharge of liquid inside the drainage and dredging pipe seat 1.

[0022] The drainage dredging pipe seat 1 includes a drainage pipe seat 11, a drainage pipe port 12, a flange 13, a pipe seat 14, an attachment pattern 15, a bolt 16 and a plugging cover 17. The drainage pipe seat 11 is fixedly mounted with a cement air bag 21 for plugging the expansion seat 2. The drainage pipe port 12 and the flange 13 are integrally arranged on the drainage pipe seat 11. The drainage pipe port 12 is fixedly connected to the controllable valve 3. The outer surface of the drainage pipe seat 11 is provided with the attachment pattern 15. The flange 13 integrally arranged on the drainage pipe seat 11 is fixedly connected to the plugging cover 17 through the bolt 16. The pipe seat 14 integrally arranged on the flange 13 is fixed to the grouting pipe 23 of the plugging expansion seat 2. The drainage dredging pipe seat 1 has a compact and simple structure, which improves the stability and reliability of the device and simplifies the installation and maintenance process. By removing the blocking cover 17, the problem of internal blockage can be solved later, and the remaining management and drainage devices can be installed, which greatly improves the overall diversity of usage methods.

[0023] The plugging expansion seat 2 includes a cement airbag 21, an air leak hole 22 and a grouting pipe 23. The air leak holes 22 are arranged in an array on one side of the cement airbag 21. The cement airbag 21 is connected to one end of the grouting pipe 23, and the other end of the grouting pipe 23 is fixed to the pipe seat 14. The plugging expansion seat 2 adopts an expansion plugging sealing mechanism. By injecting cement slurry into the specially designed airbag, the airbag expands rapidly and fits tightly to the leak, thereby achieving efficient plugging. At the same time, the expanded airbag can also effectively protect the cement inside and prevent it from being washed away by high-speed water flow, ensuring the durability and reliability of the plugging effect. The air leak hole 22 is used to discharge the original air inside the cement airbag 21, and when the cement airbag 21 expands to a certain extent, the internal cement will be discharged from the air leak hole 22, thereby prompting the staff.

[0024] Embodiment 1:

[0025] Specifically, the attachment pattern 15 integrally provided on the drainage tube seat 11 is a spiral protrusion, and is respectively provided on the outer surface of the drainage tube seat 11, and the attachment pattern 15 is located on one side of the cement airbag 21. The attachment pattern 15 not only enhances the overall strength of the drainage tube seat 11, but more importantly, it greatly increases the friction between the device and the external cement. This spiral protrusion is carefully arranged on one side of the cement airbag 21 to ensure that the external cement fits tightly with the expanded cement airbag, thereby providing stronger stability, reliability and sealing. This allows the device to maintain stable operation even in complex environments, effectively preventing displacement or falling off due to vibration or water flow impact.

[0026] Specifically, the drainage pipe opening 12 is located on one side of the flange 13 and the sealing cover 17, ensuring that the liquid can smoothly enter or discharge through the drainage pipe opening during the flow process. It is particularly noteworthy that a sealing rubber column is provided on the inner surface of the sealing cover 17. When the sealing cover 17 is tightly closed with the drainage tube seat 11, the sealing rubber column can form an interference contact with the inner wall of the drainage tube seat 11. Interference contact means that the contact pressure between the sealing rubber column and the inner wall of the drainage tube seat 11 is greater than the pressure of the external environment, thereby achieving a more rigorous and reliable sealing effect. It can effectively prevent liquid from leaking from the drainage tube seat 11.

[0027] Specifically, the pipe seat 14 is an inverted “U” base, and a fixing hole is provided on the pipe seat 14 to allow the grouting pipe 23 to pass through. The grouting pipe 23 is located above the drainage pipe seat 11 .

[0028] Embodiment 2:
