| |
| Abstract: | There were many difficulties in the construction of the pipe jacking project in Nanhai District, Foshan, Guangdong, as it was rectangular jacking of multiple pipes with small interval and large section in soft soil strata. With 6-cutterhead rectangular-section jacking machine selected and “1-3-2-4” jump-lattice jacking method used, this project, which has the largest section in the country currently, was completed successfully. |
