Deep foundation pit slope support construction technology

The invention discloses a deep foundation pit slope support construction process which comprises the following steps: for a deep foundation pit slope formed by excavating earthwork, anchoring soil nails on the slope surface from top to bottom along the longitudinal direction of the slope; paving a support surface layer on the slope surface from top to bottom; steel wire ropes are arranged on the basis of the soil nails in the longitudinal direction and the transverse direction of the side slope, and the two ends of each steel wire rope are tensioned through steel wire rope traction winding equipment; a tension sensor is mounted on a steel wire rope arranged in the longitudinal direction of the slope; edge pressing anchoring treatment is conducted on the slope top and the slope bottom of the side slope; and deep foundation pit slope supporting is completed. The method is high in construction speed, controllable in quality, capable of effectively ensuring the stability of the deep foundation pit slope, environm
