Successful Launch of Pipe Jacking Between Shaft No. 8 and Shaft No. 7 of the Huanbei Guangdong Project (Section D4)

Date: November 2025

Location: Guangdong Province, China

Project Name: Huanbei Guangdong Project

Project Type: Water Supply Project

Equipment: Tangxing Technology HRC 2200mm Rock Pipe Jacking Machine

Jacking Distance: 650 meters

Geology: Fully weathered basalt soil and strongly weathered basalt strata

Project Challenges: The pipe jacking section passes beneath multiple major access roads in Yingli Town, closely adjacent to residential buildings and the G207 National Highway. The primary geological strata consist of fully weathered basalt soil and strongly weathered basalt, with fully weathered rock. The overall construction environment is highly complex.

Project Significance: This successful launch provides valuable technical experience for upcoming long-distance pipe jacking sections exceeding 500 meters. It serves as an important demonstration for improving efficiency and accelerating the overall construction progress of the project.
