Location: Shanghai Pudong New Area

Equipment: 4000mm slurry balance micro tunnel boring machine

Features: Long pipe jacking distance (533 meters), curved pipe jacking, complicated road section

Significance：The first 4-meter curved pipe jacking of the project was successfully completed. The over-excavation in the early stage of the project caused severe wear on the cutter head. Tangxing's technical guidance was then given to ensure the subsequent pipe jacking was carried out in an orderly manner. The completion of the project will effectively reduce the rainy season overflow in the area.
