[0002] During the construction of PCCP pipelines, external joint grouting is a crucial step in ensuring the sealing of pipeline connections and the overall structural stability. Traditional external joint grouting methods can, to a certain extent, meet the basic requirements of grouting, providing a certain guarantee for the installation and use of PCCP pipelines.

[0003] However, existing grouting tapes for PCCP pipelines have many shortcomings. On the one hand, most tapes are ineffective in preventing grout leakage when wrapping the outer seams of the pipeline, affecting the grouting quality and potentially reducing the pipeline's sealing and structural stability. On the other hand, existing tapes are not convenient or quick to use, and the installation and disassembly process is cumbersome, consuming time and manpower, thus reducing construction efficiency. In addition, some tapes have low turnover rates, increasing construction costs, and their adaptability to different environmental conditions is poor, failing to meet the requirements of modern PCCP pipeline construction for high efficiency, low cost, and high quality.

[0004] To address these issues, we provide a grouting tape for external joints in PCCP pipes. Utility Model Content

[0005] The purpose of this utility model is to provide a grouting strap for external joint grouting of PCCP pipelines.

The thickness of the strap body 1 is 4mm, the diameter of the steel wire rope 2 is 8mm, and the threaded rod 4 and the threaded tube 3 are made of the same material. The threaded tube 3 includes a base layer 31, a reinforcing layer 32 and a weather-resistant layer 33. The base layer 31 is made of stainless steel, the reinforcing layer 32 is made of chromium nitride, and the weather-resistant layer 33 is made of polyurethane.

[0029] Specifically: The limiting groove 11 can fix the position of the fastening wire rope 2, preventing it from shifting during use, ensuring the fastening effect of the wrapping tape on the pipeline, further improving the ability to prevent grout leakage, and ensuring grouting quality. The thickness of the wrapping tape body 1 is 4mm, and the diameter of the fastening wire rope 2 is 8mm. This designed specification ensures that the wrapping tape has sufficient strength and fastening force to meet the actual needs of PCCP pipeline external joint grouting, improving the practicality and reliability of the wrapping tape. It is also noted that the threaded rod 4 and the threaded pipe 3 have the same material composition and are composed of a base layer 31, a reinforcing layer 32, and a weather-resistant layer 33, making the threaded rod 4... With consistent performance with the threaded tube 3, the base layer 31 provides strength and corrosion resistance, the reinforcing layer 32 enhances hardness and wear resistance, and the weathering layer 33 improves weather resistance and extends service life, ensuring long-term stable use in different environments.
