ClientBusan Metropolitan City
Year2023 - 2024
LocationBusan, Korea
Scale
(1) Collection and Review of Basic Data
(2) Pipeline and Site Survey
-Review of Pipeline Status and Detailed Inspection Results (CCTV and Visual Inspection)
-Survey of Pipeline and Manhole Status: L=20.33km
(3)Detailed Design
-Replacement and Maintenance of Aging Sewer Pipes (D200mm ～ D2,200mm): L=20.33km
-Selection of Non-Trenchless Maintenance Methods for Aging Sewer Pipes
The purpose of this project is to repair aging sewer pipelines that are buried throughout Busan Metropolitan City, focusing on the main trunk sewer pipelines undergoing the "Busan Metropolitan City Aging Sewer Pipeline Detailed Inspection (Phase 2)" since 2019. The project aims to address structural and functional defects discovered in the selected superior (combined) sewer pipelines. Taking into account site conditions, the importance of the pipelines, and the severity of the defects, the project will undertake systematic and efficient design for repair works. By improving the durability of public sewerage systems, the project aims to prevent road (ground) subsidence caused by leaks and pipeline damage, thereby establishing a safe urban environment.
