金皇大厦高１８８ｍ，地上４７层，地下３层，大厦地下支护结构采用地下连续墙，其功能集挡土、防水和承重，是天津市目前最深的地下连续墙。地下连续墙的施工质量关系到整体工程的安危，必须精益求精。本工程地下连续墙工程在槽段开挖精度、槽段安全维护、泥浆控制、钢筋笼焊制、混凝土质量控制以及施工接缝的处理等各方面都做了精心设计和施工，某些技术问题独有创新，从而保证了优良的工程质量。
Jinhuang Building is 188m high, with 47 floors above the ground and 3 floors underground. The underground supporting structure of the building adopts underground continuous walls. Its function set is retaining earth, waterproof and bearing. It is currently the deepest underground continuous wall in Tianjin. The construction quality of underground continuous walls is related to the safety of the whole project and must be improved. The underground continuous wall project of this project has been carefully designed and constructed in terms of excavation precision, slot section safety maintenance, mud control, reinforcement cage welding, concrete quality control, and construction joint processing in the trench section. Unique innovation, thus ensuring excellent project quality.
