Location: Suizhou City, Hubei Province
Equipment: 1500 rock micro tunnel boring machine
Feature: full-face hard rock, high rock strength, and traversing mountains
Significance:The "explosion method" was originally adopted for a section of the water delivery network of the project, but it was not applicable. In consequence, the trenchless pipe jacking method was used to excavate the mountain with a total length of 290 meters to lay water pipelines. Finally, the excavation broke through successfully.
