In the restoration project of Dongjiadu section of Shanghai Metro Line 4, repeated freezing method was used to repair the collapsed tunnel at the bottom of Huangpu River, which overcame the phenomenon of sand blasting and water spraying caused by horizontal drilling, strictly controlled various technical parameters of freezing in complex strata, and effectively controlled melting settlement by forced thawing to protect the surrounding environment.

At the same time, for the first time, the project constructed an ultra-deep diaphragm wall of over 60 meters in soft soil stratum, and for the first time, it used a full rotary drilling rig to clean a large area of ultra-deep underground complex obstacles, and successfully applied the technology of large-depth and large-diameter high-pressure jet grouting pile at the bottom of ultra-deep foundation pit.
