The base 1 is arranged at the periphery of the target pile foundation hole 5, and the operating platform 2 is arranged above the base 1; the operating platform 2 is provided with a middle hole, and the middle hole is sleeved outside the target pile foundation hole 5; the protective mesh 3 is hinged to the operating platform 2 and is arranged above the target pile foundation hole 5; the protective fence 4 is detachably installed at the side of the operating platform 2.

[0019] Specifically, the base 1 is welded with 160mm*63mm*6.5mm channel steels on all sides, and the four corners of the inner reinforcing plate are welded with 50mm*37mm*4.5mm channel steels and the surrounding channel steels to make the base 1 more stable. Preferably, the material of the operating platform 2 includes an anti-slip steel plate. The operating platform 2 is connected to the base 1 by welding or bolts.

[0020] In the embodiment of the utility model, a base 1 formed by welding channel steel and stiffening plate is first arranged around the target pile foundation hole 5, and then an anti-skid steel plate (i.e., operating platform 2) with a middle hole (the diameter of the middle hole is equivalent to the diameter of the target pile foundation hole 5) is laid flat on the base 1, and then the anti-skid steel plate is fixed to the base 1 by welding or bolts.

[0021] Specifically, Figure 1 As shown, a handle 6 is also provided on the protective mesh 3 to facilitate the opening and closing of the protective mesh 3.

[0022] Preferably, if Figure 1 As shown, the protective mesh 3 is composed of two semi-hexagonal meshes, which are respectively arranged on both sides above the target pile foundation hole 5. A handle 6 is provided on each semi-hexagonal mesh. By pulling the handle 6, the opening and closing of the protective mesh 3 can be controlled.

[0023] Figure 2 1 is a top view of a protective mesh in an open state according to an embodiment of the utility model. Figure 2 As shown, after the protective mesh 3 is opened by pulling the handle 6 , the target pile foundation hole 5 is completely exposed to the outside through the middle hole set on the operating platform 2 .
