[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 A deep foundation pit support plate for a building comprises a base 1, a first support plate 2, a second support plate 3 and a third support plate 4. The base 1, the first support plate 2, the second support plate 3 and the third support plate 4 are arranged in sequence from bottom to top. The tops of the base 1, the first support plate 2, the second support plate 3 and the third support plate 4 are all provided with a plurality of water retaining slots 5. The bottoms of the first support plate 2, the second support plate 3 and the third support plate 4 are all connected with a plurality of water retaining plugs 6. Each water retaining plug 6 is respectively plugged into In the corresponding water-retaining slot 5, a first ear plate 7 is connected to the upper end of one side of the first support plate 2, a first slot 8 is provided on the first ear plate 7, a nut 9 is rotatably connected in the first slot 8, a bolt 10 is threadedly connected in the nut 9, and a second ear plate 11 is connected to the lower end of one side of the second support plate 3, a second slot 12 is provided on the second ear plate 11, the threaded section of the bolt 10 is arranged in the second slot 12, and the nut section of the bolt 10 is arranged in the second ear plate 11 and is located above the second slot 12.

[0022] Through the cooperation between several water-retaining slots 5 and water-retaining plug plates 6, the assembly gap between the support plates forms multiple bends, thereby effectively preventing moisture in the soil on the side wall of the foundation pit from seeping into the foundation pit, thereby improving the protection performance. Through the cooperation between the first ear plate 7, the first notch 8, the nut 9, the bolt 10, the second ear plate 11 and the second notch 12, positioning is provided for the assembly between the support plates, preventing lateral sliding of the support plates after installation, and improving the overall effect after the connection between the support plates, reducing the assembly gap, and making the installation and disassembly between the support plates more convenient and quick.

[0023] Specifically, in this embodiment, the first support plate 2, the second support plate 3 and the third support plate 4 are all movably connected to the base 1 through a detachable diagonal support rod 13, providing temporary support for the first support plate 2, the second support plate 3 and the third support plate 4, thereby improving the support effect.

[0024] Specifically, in this embodiment, the width of the first notch 8 is greater than the minimum width of the nut 9 , thereby providing sufficient rotation space for the nut 9 .

[0025] Specifically, in this embodiment, a support shaft 14 is connected to the outer wall of the nut 9, and the support shaft 14 is rotatably connected to the inner wall of the first slot 8, so that the nut 9 can rotate with the support shaft 14 as the center under the action of external force, and the integrity of the connection between the nut 9 and the first ear plate 7 is improved.

[0026] Specifically, in this embodiment, the width of the second slot 12 is greater than the outer diameter of the threaded section of the bolt 10 and less than the minimum width of the nut section of the bolt 10, so that when the bolt 10 is screwed into the nut 9, the nut of the bolt 10 can apply pressure to the second ear plate 11.
