Description

Technical Field

[0001] The utility model relates to the technical field of safety protection facilities, in particular to a novel assembled protection fence for an inspection well. Background Art

[0002] During municipal road construction work, the manhole covers need to be opened frequently. Since the manhole openings are exposed for a long time, temporary protection is required for the manhole openings.

[0003] At present, inspection well openings are mostly protected by iron horse guardrails. On the one hand, such guardrails cannot be fixed, are easy to overturn, and are easily moved by external forces, resulting in poor protection effects. On the other hand, multiple guardrails are required to achieve protection, and the installation of each inspection well protection facility is time-consuming and inefficient. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problem and provides a novel assembled guardrail for an inspection well.

[0005] The utility model is realized through the following technical scheme: a novel assembled guardrail for an inspection well, characterized in that it comprises two semicircular guardrails with the same structure, each guardrail is composed of a surrounding frame and a fixed frame, the surrounding frame comprises a plurality of semicircular rings 1, the upper and lower semicircular rings 1 are connected by a vertical protective pipe 1, and a protective net is provided between adjacent vertical protective pipes 1; the fixed frame is arranged below the surrounding frame, the fixed frame comprises a plurality of semicircular rings 2 which are concentric with the semicircular rings and have different diameters, the upper and lower semicircular rings 2 are connected by a vertical protective pipe 2, wherein the top semicircular ring 2 is also connected to the bottom semicircular ring 1 by a plurality of horizontal fixed pipes.

[0006] Furthermore, the two semicircular guardrails are connected by assembling buckles, and the buckles include a draw hook and a buckle, and the draw hook and the buckle are respectively installed on the enclosure frames of different semicircular guardrails.

[0007] Furthermore, the diameter of the second semicircular ring is smaller than the diameter of the first semicircular ring.

[0008] Furthermore, a warning sign is provided outside the enclosure frame.

[0009] Compared with the conventional iron horse guardrail protection method, the beneficial effect of the utility model is that the guardrail is fixed to the inspection well shaft by a socket method, which improves the stability of the guardrail and prevents the guardrail from being easily moved by wind or other external forces.

[0010] The guardrail of the utility model is firmly fixed without damaging the road surface, is convenient to install and remove, and can effectively prevent the guardrail from overturning and shifting after being fixed.

[0011] The protective fence of the utility model has a high turnover rate and reduces construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with embodiments.

[0018] like Figures 1 to 4 As shown, a new type of inspection well assembled guardrail 1 is characterized in that it includes two semicircular guardrails 1 with the same structure, each guardrail 1 is composed of a protective frame 2 and a fixed frame 4, the protective frame 2 includes a plurality of semicircular rings 201, the upper and lower semicircular rings 201 are connected by a vertical protective pipe 202, and a protective net 203 is arranged between adjacent vertical protective pipes 202, and the protective net 203 is made of wire mesh; the fixed frame 4 is arranged below the protective frame 2, the protective frame 2 and the fixed frame 4 are connected to form a whole, the fixed frame 4 includes a plurality of semicircular rings 2401 that are concentric with the semicircular ring 201 and have different diameters, the upper and lower semicircular rings 2401 are connected by a vertical protective pipe 2402, wherein the top semicircular ring 2401 is also connected to the bottom semicircular ring 201 by a plurality of horizontal fixed pipes 3.

[0019] The two semicircular guardrails 1 are connected by a buckle 6, that is, they form a circular closed ring after assembly. The buckle 6 includes a hook 601 and a buckle 602. The hook 601 and the buckle 602 are respectively installed on the enclosure frame 2 of different semicircular guardrails 1, and the hook 601 is buckled into the buckle 602 for fixation.

[0020] In order to facilitate the insertion of the fixed frame 4 into the wellbore, the diameter of the semicircular ring 2 401 is slightly smaller than the diameter of the inner wall of the wellbore. For better protection effect, the diameter of the semicircular ring 2 401 is smaller than the diameter of the semicircular ring 1 201.

[0021] In order to improve the warning effect, a warning sign 5 is further provided outside the enclosure frame 2 .

[0022] Specifically, the two semicircular guardrails 1 adopt a "large and small head" socket structure, that is, the diameter of the enclosing frame 2 is larger than the diameter of the fixed frame 4. The enclosing frame 2 and the fixed frame 4 are both composed of at least two semicircular rings. The fixed frame 4 is inserted into the socket formed by the ground and the wellbore as a plug-in to form a socket structure, which realizes the close combination of the fixed frame 4 and the road surface and the side of the inspection wellbore, thereby improving stability.

[0023] Before installing the guardrail, necessary warning facilities should be set up in advance around it to guide the way; during installation, the manhole cover should be opened, and the guardrail 1 on one side of the manhole cover should be inserted into the wellbore first, that is, the fixed frame 4 should be inserted into the wellbore and close to the wellbore, and then the guardrail 1 on the other side should be installed using the same method. Finally, the connection between the two guardrails 1 should be spliced ​​and fixed with buckles 6.

[0024] Except for the technical features described in the specification, the other technical features are known technologies to those skilled in the art.
