Description

Technical Field

[0001] This invention relates to the field of water conservancy construction, and in particular to a seepage prevention structure for water conservancy construction pipelines. Background Technology

[0002] In water conservancy construction, pipeline seepage prevention is a crucial link in ensuring the safe and efficient operation of water conveyance projects. Pipeline leakage not only wastes water resources but may also cause problems such as foundation erosion and structural damage. Preventing leakage during water conveyance, reducing water resource loss, avoiding foundation softening, pipeline settlement or collapse caused by leakage, reducing groundwater corrosion of pipelines, extending pipeline service life, and preventing sewage or chemical leakage from polluting soil and water bodies are all essential. This requires selecting standard pipe materials, rubber rings, and anti-corrosion coatings to avoid leakage caused by inferior materials, promoting trenchless repair technologies (such as CIPP UV curing repair), reducing the environmental impact of construction, and effectively solving the problem of water conservancy pipeline seepage prevention through scientific material selection, meticulous construction, and strict management, thus ensuring the long-term safe operation of water conservancy projects.

[0003] In existing technologies, during water conservancy construction, the connection between the ends of underground pipelines needs to be sealed to avoid leakage. To strengthen the sealing of the connection, we propose a seepage-proof structure for water conservancy construction pipelines. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes a seepage prevention structure for water conservancy construction pipelines.

[0005] To solve the above-mentioned technical problems, the present invention adopts a seepage prevention structure for water conservancy construction pipelines, including two end pipes, with a seepage prevention pipe provided between the two end pipes. A sealing device is fixedly connected to the inner wall of the seepage prevention pipe, and a reinforcing device is slidably provided at both ends of the seepage prevention pipe. A limit device is slidably connected to the side wall of the two end pipes at corresponding positions, and multiple grouting devices are provided through the side wall of the seepage prevention pipe.

[0006] Preferably, the sealing device includes two inner sealing rings fixedly connected to the inner wall of the seepage-proof pipe, and the two inner sealing rings are respectively located at the outer ends of the two end pipes connecting parts.

[0007] Preferably, the reinforcing device includes an outer sealing ring slidably disposed at the port of the seepage-proof pipe, and guide blocks are fixedly connected to the opposite sidewalls of the outer sealing ring. Two corresponding grooves are provided through the inner wall of the seepage-proof pipe at the corresponding positions, and the two guide blocks are slidably connected in the two grooves respectively.

[0008] Preferably, the limiting device includes a clamp plate slidably disposed on the side wall of the end pipe, a connecting seat fixedly connected to the side wall of the seepage prevention pipe at the corresponding position, a threaded groove being provided through the side wall of the connecting seat, an adjusting screw being threadedly connected in the threaded groove, and the adjusting screw penetrating the side wall of the clamp plate.

[0009] Preferably, the grouting device includes a plurality of grouting holes that penetrate the side wall of the seepage-proof pipe. The plurality of grouting holes are respectively disposed in the gap between the corresponding outer sealing ring and the inner sealing ring. A connecting rod is provided at the opening of each adjacent pair of grouting holes.

[0010] Compared with the prior art, the beneficial effects of the present invention include: by setting up a reinforcing device, a limiting device and a grouting device to cooperate with each other, the seepage-proof pipe foundation inserted between the two end pipes is sealed at the connection point by two inner sealing rings. After the seepage-proof pipe is inserted, seepage-proof mud material can be injected into the gap between the inner sealing ring and the outer sealing ring through multiple grouting holes. Rotating the adjusting screw at the corresponding position can drive the corresponding clamp to slide on the end pipe and squeeze the outer sealing ring on the corresponding side, thereby ensuring that there are no gaps in the grouting inside the seepage-proof pipe, enhancing the seepage-proof performance. The connecting rod can play the role of sealing the grouting hole and can be disassembled at any time after grouting is completed. Attached Figure Description

[0016] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0017] According to one embodiment of the present invention, Figure 1-2 The diagram illustrates a seepage-proof structure for a hydraulic construction pipeline, comprising two end pipes 1, with a seepage-proof pipe 5 connecting them. This connection effectively prevents external moisture infiltration, ensuring the long-term stability of the pipeline system. A sealing device is fixedly connected to the inner wall of the seepage-proof pipe 5. This sealing design provides uniform sealing pressure in all directions, preventing localized leakage. The sealing device includes two inner sealing rings 9 fixedly connected to the inner wall of the seepage-proof pipe 5, made of high-quality rubber material with excellent elasticity and corrosion resistance. The two inner sealing rings 9 are located at the outer ends of the joint between the two end pipes 1, forming a double sealing barrier that significantly improves the waterproofing effect.

[0018] The geotextile 5 features slidable reinforcing devices at both ends, an adjustable design that allows for precise adjustments based on site conditions. The reinforcing devices include outer sealing rings 7 slidably mounted at the ends of the geotextile 5, made of high-strength composite material to withstand mechanical impacts during construction. Guide blocks 8 are fixedly connected to opposite sidewalls of the outer sealing rings 7, ensuring precise positioning of the sealing rings during assembly and preventing misalignment. Two corresponding grooves are threaded through the inner wall of the geotextile 5 at corresponding positions, with a machining accuracy of 0.1 mm, ensuring tight fit between components. The two guide blocks 8 are slidably connected within the two grooves, a guiding mechanism that ensures smooth movement while preventing component detachment.

[0019] In this design, both end pipes 1 at corresponding positions have sliding limit devices connected to their side walls. This limit design can adapt to the application requirements of different pipe diameters. The limit device includes a clamping plate 2 that slides on the side wall of the end pipe 1. It undergoes a special surface treatment, providing excellent anti-friction and wear performance. A connecting seat 4 is fixedly connected to the side wall of the corresponding leak-proof pipe 5. Utilizing integrated casting technology, its structural strength is more than twice that of traditional welded parts. A threaded groove is provided through the side wall of the connecting seat 4, using standard thread specifications for easy maintenance and replacement. An adjusting screw 3 is threaded into the groove and equipped with an anti-loosening washer to ensure it will not loosen over long-term use. The adjusting screw 3 penetrates the side wall of the clamping plate 2 and features an adjustable scale design, allowing for visual control of the tightening force.

[0020] Specifically, multiple grouting devices are installed through the sidewall of the geotextile 5, an innovative design that enables secondary remediation after seal failure. The grouting devices include multiple grouting holes 11 penetrating the sidewall of the geotextile 5. The hole diameters are optimized for fluid dynamics to ensure uniform diffusion of the grouting material. The multiple grouting holes 11 are respectively installed through the gap between the corresponding outer sealing ring 7 and inner sealing ring 9, arranged in a ring array to form 360-degree all-around protection. Connecting rods 6 are connected to the openings of adjacent grouting holes 11, employing a quick-release design for rapid operation in emergencies.

[0021] In this embodiment, the operator inserts the geotextile 5 into the two end pipes 1 to achieve docking. The two inner sealing rings 9 can provide a basic seal at the docking point. After pulling out the corresponding connecting rod 6, the grouting hole 11 can be exposed. Through the grouting hole 11, anti-seepage grout (this is the prior art, which can be polyurethane grout or composite grout) can be injected into the geotextile. Rotating the adjusting screw 3 on one side allows it to move on the connecting seat 4 and drive the clamp 2 to slide on the end pipe 1. The clamp 2 can squeeze the corresponding outer sealing ring 7, thereby squeezing and filling the gap between the outer sealing ring 7 and the inner sealing ring 9, enhancing the anti-seepage function and facilitating subsequent curing.

[0022] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
