Hot rolling plant plate zone extra-large deep foundation pit group construction technological process design method

The invention discloses a hot rolling plant plate zone extra-large deep foundation pit group construction technological process design method. The method comprises the steps of determining an excavation design thought; determining a supporting form; designing construction procedures; compiling an emergency plan; excavating deep foundation pits. According to the hot rolling plant plate zone extra-large deep foundation pit group construction technological process design method, the whole process including the excavation design thought, the supporting form, the construction procedure design, the emergency plan compiling, the deep foundation pit excavation and the like is started, the influence of the complex surrounding environment, the complex geological condition, the complex relation between the foundation pits and the like on the plate zone extra-large deep foundation pit group construction is avoided, the collapse accident of the deep foundation pit group in the excavation process is prevented, the accident
