The bottom ends of both ends of the arc-shaped frame 3 are connected to the two columns 2 by second bolts. The first bolts allow the arc-shaped frame 3 to be disassembled and installed, facilitating its transportation. At the same time, it can be quickly installed during use.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The first support member 15 includes a threaded sleeve 5, with a threaded rod 6 internally threaded to the threaded sleeve 5. A lug 7 is fixed to the top of the threaded sleeve 5, and the lug 7 is connected to the mounting base 4 via a connecting shaft. A second lug 8 is fixed to the bottom of the threaded rod 6, and the second lug 8 is connected to the mounting base 13 on the top of the fixed base 12 via the connecting shaft.

After moving to the appropriate position, the positions of the threaded sleeve 5 and the threaded rod 6 are fixed by the fixing bolt 19. Then, the threaded sleeve 5 is rotated outward until the fixing seat 12 contacts the ground. Then, the ground nails 14 can be driven in. The threaded rod 10 is then rotated underground until it extends beyond the threaded sleeve 9. The fixed seat 12 at the bottom of the threaded sleeve 9 contacts the ground. The threaded sleeve 9 and the threaded rod 10 are then connected by the fixing bolt 19 on the threaded sleeve 9. Finally, the ground nail 14 at the bottom of the fixed seat 12 at the bottom of the threaded sleeve 9 is driven into the ground, thereby forming a solid diagonal support on both sides of the arch frame, improving the overall strength of the arch frame. Furthermore, the movement of the threaded rod 16 and the threaded rod 10 makes the support member 15 and the support member 26 more widely applicable.

[0029] Subsequently, concrete is poured into the first pouring cavity 20 through the pouring hole. The concrete will fall down into the second pouring cavity 21 to connect the first pouring cavity 20 and the second pouring cavity 21, thereby strengthening the structure.
