Location: Longgang District, Shenzhen
Equipment : 3500 rock micro tunnel boring machine
Feature: crossing the main road, high requirements for land subsidence, complex surrounding environment
Significance: The pipe jacking of the project section crosses the main road of the city and has high requirements for ground settlement. Therefore, Tangxing 3.5m rock MTBM was used. The total length of the pipe jacking section is 80 meters, and the jacking depth is 4.5-10 meters. The equipment started smoothly. It marks an important progress in the comprehensive pipe gallery of Yongqin Road.
