Abstract：
Tianjin Jinde Garden ｅngineering is located in a busy zone, the engineering site is narrow and is adjacent to the primary road and a residential area. During the construction of the underground engineering, bored filling pile is used to retain the earth, deep mixing pile is used to stop the water, and two eye-shaped horizontal reinforced concrete supports are set. Earth is excavated by using central island type rapid excavation method, with monitoring on deformation and settlement of supporting structures, surrounding roads and buildings. General temperature control measure is adopted for the foundation slab massive concrete to prevent the generation of noxious fracture, and basement external wall single-side formwork technique is successfully used to guarantee engineering quality and safety of surrounding buildings and environment.
