The non excavation lining repair method is used for pipeline crack and leakage, combined with resin glue A+B and fiberglass cloth for repair, which is an efficient and economical solution. The following are the advantages and steps of this method:
Advantages:
1. * * Non excavation repair * *: No need for large-scale excavation, reducing the impact on the environment and traffic.
2. * * Quick Repair * *: The resin adhesive cures quickly, restoring the functionality of the pipeline in a short period of time.
3. * * Cost saving * *: Reduce excavation and restoration costs, and lower overall construction costs.
4. * * Strong Durability * *: Fiberglass cloth and resin adhesive provide long-lasting repair effects.
5. Wide applicability: Suitable for various pipeline materials and diameters.
Repair steps:
1. Pipeline cleaning: Use high-pressure water guns or mechanical tools to remove dirt and sediment from the inner wall of the pipeline.
2. Crack treatment: Polish the crack area to ensure a smooth surface for easy bonding with resin adhesive.
3. Resin Mixing: Mix resin glue A+B in proportion and stir evenly.
4. Fiberglass cloth laying: Apply the mixed resin adhesive onto the fiberglass cloth and tightly adhere it to the crack.
5. * * Curing * *: The resin adhesive solidifies in a short period of time, forming a strong protective layer.
6. * * Quality Inspection * *: After repair, inspect the repaired area to ensure no water leakage and structural integrity.
matters needing attention:
-* * Safety protection * *: Construction personnel must wear protective equipment to avoid contact with resin glue.
-* * Environmental Control * *: Pay attention to temperature and humidity during construction to ensure that the resin adhesive is properly cured.
-Material selection: Choose appropriate resin glue and fiberglass cloth based on the pipeline material and crack condition.
This method can quickly and economically repair pipeline cracks, reduce the impact on the environment and traffic, and is suitable for multiple fields such as municipal, industrial, and construction.


The pipeline maintenance airbag is made of imported special rubber combined with a double-layer high-strength elastic fiber structure, which is extruded and vulcanized. The two ends of the airbag are fixed by metal structural plates and equipped with symmetrical angle wheels to ensure a stable channel for the airbag in the pipeline, and can be connected to closed-circuit television. Suitable for different types of cracks, leaks, misalignment, and partial corrosion in pipelines. Suitable for DN50-1500mm pipes of various materials.
Pipeline sealing airbag is a multi specification and multi shape rubber product produced by high-temperature vulcanization process of polymer synthetic materials such as rubber and fiber fabrics, used for water transmission, sewage discharge, and dredging maintenance of pipeline culverts. It can quickly block the flow of different diameters, surfaces, and locations, making it an ideal tool for underground water transportation, drainage, and sludge treatment pipelines.
