Ultra-deep foundation pit group asynchronous excavation clockwise and anticlockwise combined safety construction method

The invention relates to the field of building engineering construction, and provides an ultra-deep foundation pit group asynchronous excavation clockwise and anticlockwise combined safety construction method which comprises the following steps: adopting a large-rigidity enclosure structure when a construction scheme is designed; arranging connecting beams between the adjacent foundation pits; arranging drawing strips in the foundation pits and between the adjacent foundation pits, and reinforcing the skirt edge foundation; controlling the error height during foundation pit excavation; predicting the deformation trend of the foundation pit group by using a data inversion system, and guiding the next foundation pit deformation control key point; when the deformation amount of the foundation pit and the surrounding buildings exceeds the limit or the displacement rate exceeds the early warning value, taking corresponding deformation control measures; excavating earth below the reversed plate and synchronously co
