Project Overview
This project involves pipeline replacement and encroachment remediation for the Wu-Xin Pipeline at the Hu Clan Ancestral Hall in Xiaonan District, Xiaogan City, Hubei Province. The encroachment section spans from pile WXXG0187 to WXXG0192, with the ancestral hall located just 2 meters from the pipeline—posing a significant safety risk.
To eliminate the encroachment hazard and ensure long-term pipeline integrity, a 51.69m pipeline replacement will be conducted. The new route will bypass the ancestral hall from the northeast, increasing the minimum clearance to 11 meters, complying with safety regulations and operational requirements.
