During the excavation stage, the long-arm excavator and the earth-moving truck work at the side of the trestle, and there is no need to set up edge protection at the side of the trestle. The excavation opening on the trestle needs edge protection when it is not in use to prevent people from falling, but the edge protection of the trestle foundation pit is mostly fixed, which is expensive to install and remove at a time and affects the construction period. Therefore, the edge protection of the excavation opening is often missing when it is not in use.

The components are detachably connected to each other, which is convenient and flexible for assembly and disassembly, and can save installation and disassembly time.

[0036] Specifically, the fixed support 1 includes a slot body 11 with an opening facing inward, the opening of the slot body 11 is larger inside and smaller outside, and is used to connect the upright pole 2. More specifically, the opening of the slot body 11 includes a first rectangular parallelepiped cavity located inside and a second rectangular parallelepiped cavity located outside, and the width of the first rectangular parallelepiped cavity is greater than the width of the second rectangular parallelepiped cavity. In addition, the opening of the slot body 11 is through-through, and the upright pole 2 can be wedged into the left and right sides of the fixed support 1, respectively.

[0037] More specifically, if Figure 2 and Figure 3 As shown, a fixing plate 12 is connected to the side of the trough body 11, and a through hole is opened in the fixing plate 12. Bolts pass through the through hole to fix the fixing support 1 to the ground. In this embodiment, the fixing plates 12 are respectively fixed to both sides of the trough body 11, and the fixing support 1 is fixed to the ground by using expansion bolts 13 passing through the through hole. Fixing the two sides of the trough body 11 can make the fixing support 1 stably fixed to the ground.

[0038] Specifically, if Figure 2 and Figure 4 As shown, the vertical pole 2 is a vertically arranged rod structure, preferably a square tube, and a connecting plate 21 is connected to its lower end, and the connecting plate 21 is adapted to the groove body of the fixed support 1. In this embodiment, the connecting plate 21 is made of steel plate, and the connecting plate 21 forms a wedge-shaped connection with the groove body 11. The connecting plate 21 at the lower part of the vertical pole 2 is slightly narrower than the opening of the groove body 11, and the connecting plate 21 can be wedged into the first rectangular cavity of the groove body 11. The width of the vertical pole 2 is less than or equal to the width of the second rectangular cavity in the groove body 11.

[0039] More specifically, the vertical pole 2 is also provided with at least two support ring frames 4 for placing the cross bar 3. In this embodiment, two support ring frames 4 are arranged on each vertical pole 2, each support ring frame 4 is a ring body with an opening formed by steel bars or thick iron wires, etc., and the support ring frame 4 is fixed to the vertical pole 2. The support ring frame 4 has an opening 41, the lower end of the opening is higher than the lowest point of the inner circle of the support ring frame 4, and the height of the opening 41 is greater than the diameter of the cross bar 3, so that the cross bar can be placed in the support ring frame 4 to form a protective structure.
