The four-corner fixing block 7 is installed in the four-corner fixing groove 5 inside the inlay groove 4 and the four-corner clamping block groove 20 inside the irregular clamping block 6, so that the support column can be combined and installed.

[0032] The extended column 2 is placed on top of the support bottom column 1. By pulling the pull rod 25, the pull rod 25 squeezes the limit spring 26, and the limit spring 26 provides elastic force, enabling the pull rod 25 to slide within the sliding groove 24. The pull rod 25 is clamped within the clamping groove 23. The irregular clamping block 6 on the extended column 2 is inserted into the embedding groove 4 in the embedding block 3. The four-corner fixing block 7 is clamped within the four-corner fixing groove 5 and the four-corner clamping block groove 20, enabling the extended column 2 and the support bottom column 1 to be tightly fixed, realizing the function of facilitating the combination of the support columns and facilitating the installation and removal by workers.

[0033] In this embodiment, as Figure 1 and Figure 2 shown, a chassis 14 is provided on the outer wall at the bottom of the vertical fixed clamping plate 8, and a number of clamping and fixing holes 18 are opened on the outer walls on both sides of the vertical fixed clamping plate 8. The vertical fixed clamping plate 8 is installed on the surface of the chassis 14, and the vertical fixed clamping plate 8 clamps the outer wall of the support bottom column 1. Corresponding fixture fixing holes are opened on the outer wall of the support bottom column 1 and the outer wall of the vertical fixed clamping plate 8, realizing the function of limiting and fixing the support bottom column 1.

[0034] Specifically, as Figure 1 and Figure 2 shown, the inner wall of the clamping and fixing hole 18 is threadedly connected with a vertical fixing bolt 10, and a vertical fixing nut 9 is threadedly connected to the outer wall of the vertical fixing bolt 10. The vertical fixing nut is threadedly connected to the outer wall of the vertical fixing bolt 10, and the vertical fixing bolt 10 is threadedly connected within the clamping and fixing hole 18 of the support bottom column 1 and the vertical fixed clamping plate 8, enabling the support bottom column 1 and the vertical fixed clamping plate 8 to be fitted and installed.

The clamping screw rod 12 rotates on the clamping block 11, and the clamping fixing nut 13 rotates on the clamping screw rod 12, realizing the function of limiting the clamping screw rod 12. Furthermore, two vertical fixing clamping plates 8 can tightly clamp the supporting bottom column 1.

[0038] In this embodiment, as Figure 6 and Figure 7 shown, hollow grooves 19 are formed in outer walls of tops of the supporting bottom column 1 and the extension column 2, and a hollow steel pipe 21 is inserted into the hollow grooves 19. A sealing cover 22 is threadedly connected to an inner wall of the hollow groove 19. The hollow steel pipe 21 is of model Q235A. The hollow steel pipe 21 is placed in the hollow groove 19, and the sealing cover 22 is threadedly connected to the hollow groove 19, so that the hollow steel pipe 21 can prevent the support column from being bent.

[0039] Working principle: When in use, place the supporting bottom column 1 at a position where installation is required, fix the two vertical fixing clamping plates 8 on an outer wall of the supporting bottom column 1. The vertical fixing bolt passes through the vertical fixing nut 9 and the clamping fixing hole 18 to fix the vertical fixing clamping plate 8 on the outer wall of the supporting bottom column 1, so that the supporting bottom column 1 can be installed on the vertical fixing clamping plate 8. Rotate the clamping screw rod 12, and the clamping screw rod 12 rotates within the clamping fixing nut 13, so that the two clamping blocks 11 are tightly attached together, thereby enabling the vertical fixing clamping plate 8 to be tightly attached and installed. Rotate the cross fixing bolt 17, and the cross fixing bolt 17 passes through a fixing square groove threaded hole in the fixing square groove 15 on the chassis 14, so that the chassis 14 with the vertical fixing clamping plate 8 can be installed on the ground. Place the extension column 2 on the supporting bottom column 1, pass an irregular clamping block 6 on the extension column 2 through an embedding groove 4 in the embedding block 3, pull the pull rod 25, and the pull rod 25 moves within the sliding groove 24. The pull rod 25 presses the limiting spring 26, and the limiting spring 26 provides elastic force. The pull rod 25 is clamped in the clamping groove 23. Install the four-corner fixing block 7 in the four-corner fixing groove 5 in the embedding groove 4 and the four-corner clamping block grooves 20 of the irregular clamping block 6, realizing the function of combined installation of the support columns. Place the hollow steel pipe 21 in the hollow groove 19, and threadedly connect the sealing cover 22 into the hollow groove 19, avoiding the problem that the support column is bent due to the pressure on the inner wall of the foundation pit.
