Sedimentation along the No. 4 Lineof Shanghai subway tunnel has been controlled due to timely and strengthened rescue efforts.
According to the local emergency rescue headquarters, the leaning Linjiang Garden Plaza above the flooded tunnel section in the city's riverfront Huangpu District has been stabilized after atemporary cofferdam was built and reinforced later with armor plates.
The eight-story building began to tilt when the subway tunnel beneath it was flooded for unknown reasons on July 1.
Rescuers have built four reinforced cement walls, with each measuring 5.5 meters high and 2.2 meters thick, at all entrances to the tunnel.
To stop the ground sedimentation, constructors pour water into the tunnel so that the pressure from outside and within can be balanced as quickly as possible. The city's employment and social security information network, employment supervision telephone hot-line 12333, and settlement centers for social insurance which were suspended for days after the accident returned to operation Tuesday.
Once the danger is fully controlled, the headquarters said that tunnel reconstruction may resume.
