Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0019] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of protection of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement of the method of the present utility model under the premise of the concept of the present utility model falls within the scope of protection required by the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a deep foundation pit support structure for high-rise buildings, including a support plate 1. A fixing strip 3 is fixed to one side wall of the support plate 1. A fixing groove 2 is provided on the other side wall of the support plate 1. Symmetrically distributed fixing holes 17 are provided in the fixing strip 3 along the vertical direction. Symmetrically distributed fixing channels 4 are provided on the outer wall of the support plate 1. A fixing rod 5 is slidably connected to the inner wall of the fixing channel 4. One end of the fixing rod 5 extends outside the fixing channel 4 and is jointly fixed with a pulling plate 6. A connecting spring 7 is fixed between the pulling plate 6 and the outer wall of the support plate 1. Among them, the elastic force of the connecting spring 7 can ensure the stability of the initial state of the fixing rod 5.

[0021] A connecting groove 8 is provided on the side wall of the fixing strip 3 away from the support plate 1. A pressing plate 9 is slidably connected to one side wall of the connecting groove 8. A connecting channel 13 is provided on the outer wall of the fixing strip 3. A connecting shaft 11 is rotatably connected between the inner walls of the connecting channel 13 with damping. One end of the connecting shaft 11 extends into the connecting groove 8. A threaded groove 10 is provided on the side wall of the pressing plate 9 close to the connecting shaft 11. A transmission thread is provided on the outer surface of the connecting shaft 11. One end of the connecting shaft 11 extends into the threaded groove 10. The connecting shaft 11 and the threaded groove 10 are in threaded transmission connection. The other end of the connecting shaft 11 extends outside the fixing strip 3 and is fixed with a rotating plate 12. The rotating plate 12 and the connecting shaft 11 are perpendicularly arranged, and the position fixed by the pressing plate 9 can be adjusted by turning the rotating plate 12. A connecting plate 14 is provided on one side of the fixing strip 3. A connecting bar 15 is hinged to one side wall of the connecting plate 14. A connecting hole 16 matching the fixing rod 5 is provided in the connecting bar 15 along the vertical direction.

[0022] When using the support plate 1, if the support position is a straight line or a curve with a small curvature, directly pull the pull plate 6 on the surface of the adjacent support plate 1 through the pull plate 6. The pull plate 6 drives the fixing rod 5 to move, so that the connecting spring 7 is in a stretched state. Then move the support plate 1, and the support plate 1 drives the fixing strip 3 into the fixing groove 2. Release the pull plate 6. Under the elastic force of the connecting spring 7, the fixing rod 5 passes through the fixing hole 17 at the corresponding position on the surface of the fixing strip 3 to fix the position of the fixing strip 3, thereby connecting the two support plates 1. When there is a certain inclination angle, move the connecting plate 14, and the connecting plate 14 enters the connecting groove 8. Then rotate the rotating plate 12, and the rotating plate 12 drives the connecting shaft 11 to rotate. The connecting shaft 11 drives the pressing plate 9 to move through screw transmission, so that the pressing plate 9 presses and fixes the connecting plate 14. Then, through the pull plate 6 on the surface of the adjacent support plate 1, the pull plate 6 drives the fixing rod 5 to move, so that the connecting spring 7 is in a stretched state. Move this support plate 1, and the support plate 1 drives the connecting plate 14 to move. The connecting plate 14 drives the connecting strip 15 to move. The connecting strip 15 can be rotated to adjust the angle, so that the connecting strip 15 enters the fixing groove 2 of another support plate 1. Release the pull plate 6. Under the elastic force of the connecting spring 7, the fixing rod 5 passes through the connecting hole 16 formed on the surface of the connecting strip 15 to complete the connection of the positions of the two support plates 1, with high flexibility.
