Proliner DN1800 large diameter ultraviolet lined hose successfully applied in Shenzhen

This project is located on Lianping Road, Pingshan District, Shenzhen City, Guangdong Province. The pipeline is made of concrete and buried at a depth of 5 meters. The Pingshan River, one of the five major rivers in Shenzhen, runs through the entire area and is rich in groundwater resources.
The rainwater pipe network branches around Pingshan District converge with DN1800 rainwater pipes and are directly discharged into Pingshan River.
Due to its long service life, there are multiple cracks and damages inside the pipeline, and large transport vehicles often pass through the road surface. The pipeline has a risk of collapse and urgently needs to be repaired as a whole.

Repair Overview

Application project: UV curing repair of DN1800 rainwater pipeline

Application time: December 2021

Application address: Shenzhen, Guangdong Province

Application product: DN1800 * 12mm lining repair material

The DN1800 pipeline repair this time demonstrates its technical characteristics of non excavation, flexibility, convenience, time-saving, and no need to interrupt traffic compared to traditional excavation repair.

At the same time, the repair of large pipe diameters and wall thicknesses has accumulated a large amount of construction data for the non excavation repair industry, providing a solid foundation for the subsequent construction of large pipelines!

Fix difficulties

The difficulty of this project lies in the fact that there are basically no cases of DN1800 large diameter repair in China;
2. Due to the heavy material of the inner lining hose with a large diameter and wall thickness; Material distortion may occur when entering the well;
3. Thick repair materials may cause curing failure.
