It can be rehabilitated as a "self-sustaining" waterway with high functionality and durability.
The "Lift-in Method" is a waterway renovation method using Esron® RCP®. By utilizing non-excavation techniques, it allows for rehabilitation while minimizing the impact on the surrounding environment due to the absence of electric machinery. Additionally, it enables rehabilitation without the need to demolish the aging existing waterway. 【Features】 ■ Allows for speedy and labor-saving transportation of Esron RCP ■ Excellent elasticity, flexibility, and water tightness due to the joint structure (rubber ring) ■ Can respond to Level 2 seismic movements by following ground fluctuations due to the flexibility of the pipe body ■ With a small roughness coefficient, it allows for a size reduction of 1 to 2 sizes and a lower slope while maintaining the same flow rate as the existing waterway ■ As it is a product managed according to consistent quality standards and criteria, construction quality management is easy *For more details, please download the PDF or contact us.
