Self-sinking-type deep foundation pit retaining wall structure and construction method for underground space structure
A self-sinking-type deep foundation pit retaining wall structure, comprising a cylindrical retaining wall body (1); a ground breaking structure (2) is formed at the bottom of the cylindrical retaining wall body (1), and the cylindrical retaining wall body (1) is suitable for achieving downward ground breaking and sinking by means of the cooperation of the ground breaking structure (2) and the gravity of the cylindrical retaining wall body; and a water pipe (20) running through the cylindrical retaining wall body is cast in the cylindrical retaining wall body (1), and the water pipe (20) is provided with a water outlet (80) located at the lower end face of the cylindrical retaining wall body (1) and a water inlet (81) located at the upper end face of the cylindrical retaining wall body (1). The self-sinking-type deep foundation pit retaining wall structure further comprises resistance increasing devices (4) provided on an outer side wall (3) of the cylindrical retaining wall body (1), and the resistance increasing devices (4) are used for cooperating with a foundation (5), so as to adjust upward resistance applied by the foundation (5) to the cylindrical retaining wall body (1). In addition, further provided is a construction method for an underground space.
