[0024] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0025] Reference Figure 1-2 ,

[0026] A pipeline anti-fall net, comprising: a protective net 1, a hook 2 and a fixed structure. The protective net 1 is a stainless steel net with a spider web structure, which is corrosion-resistant and has high support strength. The edge circumferential array of the protective net 1 forms a plurality of hook rings 3, specifically six hook rings 3. The hooks 2 and the fixed structure are also provided in six groups, and the six groups of hooks 2 and the six groups of fixed structures are connected one by one. The six hooks 2 and the six hook rings 3 are hung one by one, and the fixed structure is fixed inside the pipeline by pouring concrete. When a pedestrian steps on the protective net 1, the pressure of the pedestrian on the protective net 1 is transmitted to the pipeline through the hook 2 and the fixed structure in turn. The pipeline provides an upward support force to the pedestrian through the fixed structure and the hook 2 to prevent the pedestrian from falling into the bottom of the manhole.

[0027] Specifically, the fixing structure includes: a fixing box 4 and a spring 5. The spring 5 is placed in the fixing box 4, and one end of the hook 2 away from the protective net 1 extends into the fixing box 4 and is welded and fixed to one end of the spring 5, and the hook 2 is slidably connected to the fixing box 4. The other end of the spring 5 is welded and fixed to the inner wall of the fixing box 4, and the fixing box 4 is fixed to the inside of the pipe wall by pouring concrete. When a pedestrian steps on the protective net 1, the pressure is transmitted to the spring 5 through the hook 2, and the spring 5 is stretched to buffer the pressure applied by the pedestrian to prevent the protective net 1 from breaking. If other heavy objects fall and the force applied to the protective net 1 far exceeds the pressure applied by a normal person, such as 1500N, the spring 5 will break at this time to prevent the heavy object from pulling the fixing box 4 out of the pipe and causing the pipe to rupture.

[0028] Specifically, a convex edge 6 is formed at one end of the fixing box 4 close to the protective net 1. The convex edge 6 is cast with concrete and fixed in the pipe and is clamped with the inside of the pipe. When the protective net 1 is under pressure, the pipe provides a reaction force to the convex edge 6 away from the protective net 1, making it more difficult for the fixing box 4 to be pulled out from the inside of the pipe, thereby improving the carrying capacity of the protective net 1.

[0029] Specifically, an anti-rust coating is applied on the surface of the protection net 1 to further improve the anti-rust capability of the protection net 1 .

[0030] Specifically, the surface of the anti-rust coating is smooth, and the protective net 1 scratches the pedestrian when it contacts the exposed skin of the pedestrian.

[0031] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
