In Jiaxing City, Zhejiang Province, an "underground surgery" related to urban sustainable development and people's well-being is quietly underway - the upgrading and renovation of urban sewage pipe networks. Shanghai Baojin Water Co., Ltd., as a professional force deeply engaged in the field of non excavation restoration, has successfully overcome multiple construction difficulties with its exquisite technology and advanced equipment, especially the application of high-performance UV cured hoses (UV-CIPP lining material) provided by our company. It has injected new vitality into more than 3000 meters of old sewage pipelines and written a model of "minimally invasive revitalization" of urban infrastructure.
High risk of well depth: Some inspection wells are over 8 meters deep, with strict requirements for personnel safety and equipment operation standards.
Repair of ultra long pipeline sections: A single section of pipeline with a length of 185 meters needs to be repaired, which greatly tests the structural and stability of the materials as well as the difficulty of construction operations.
Large water flow interference: The active water flow in the construction area poses a direct threat to the infiltration, bonding, and solidification of repair materials.
Faced with challenges, the professional team of Shanghai Baojin Water has chosen the industry-leading non excavation repair technology - UV-CIPP in-situ curing method, and the most critical material is the high-quality UV cured hose (lined with resin hose) provided by our company Zhejiang Youwei. The excellent performance of this core material has become a key guarantee for the success of the project.
This project fully demonstrates the core advantages of UV-CIPP non excavation repair technology, which cannot be achieved without the support of core materials
Minimally invasive construction with minimal interference: There is no need for extensive "rifling" throughout the entire process. Our efficient curing hose, combined with advanced UV curing equipment, significantly shortens the curing time and greatly reduces the impact on urban traffic, residents' lives, and the environment (avoiding traffic congestion and dust noise).
High strength and long service life: The cured inner lining tube, relying on our high-quality hose material's excellent mechanical properties (compression resistance, bending resistance) and outstanding chemical corrosion resistance and wear resistance, not only has high structural strength, but also can effectively extend the service life of the pipeline for decades, greatly reducing maintenance costs in the later stage.
Safety and environmental protection: It maximally protects the existing underground pipelines and facilities, with low safety risks during the construction process, and no harmful substances are released during the solidification process.

Guarding Green Water and Clear Waves: Repairing leaking and blocked old pipe networks, effectively preventing direct discharge of sewage, significantly improving the water environment of Pinghu City, making the river clearer and the scenery more beautiful.
Improving livability: Say goodbye to sewage overflow, odors, and mosquito breeding, create a cleaner and more comfortable living environment for residents, and ensure the safety and stability of daily water use.
Building a foundation for long-term development: A well-developed underground pipeline network is the cornerstone of urban resilience and sustainable development. The successful implementation of this project has enhanced the comprehensive urban carrying capacity of Pinghu, providing a solid guarantee for attracting investment, promoting economic development, and enhancing urban competitiveness.
Shanghai Baojin Water Co., Ltd., with its strong construction capabilities (municipal level qualification, professional equipment and personnel) and rich project experience (100+cases), has successfully applied non excavation repair technology in the Jiaxing project. In this project, the high-performance UV cured hose provided by our company serves as the core carrier of UV-CIPP technology. With its excellent material properties, it perfectly adapts to harsh working conditions such as 185 meter long repairs, providing key support for the smooth progress and high-quality completion of the project.
This cooperation is a perfect combination of advanced materials and exquisite craftsmanship, jointly composing a green chapter of "minimally invasive revitalization" of urban underground infrastructure. The successful experience of the Jiaxing project provides a reference sample for more cities to solve the problem of old pipeline networks, and also marks a new height in the application of our UV cured hoses in large-scale and difficult non excavation repair projects. We will continue to contribute to safeguarding the "bloodline" of the city and building a beautiful China!
