Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inspection wells, in particular to an inspection well with an anti-fall structure. Background Art
[0002] In urban infrastructure construction, power supply, water supply, drainage, sewage disposal, communications, cable television, gas pipelines, and streetlight lines are typically located within underground pipe networks. To facilitate the installation and maintenance of these underground infrastructure, inspection wells are typically constructed at regular intervals within straight pipe sections, at pipe intersections, at bends, and at locations where pipe diameters or slopes change. An inspection well is a vertical shaft installed within an underground pipe system, typically connecting sewage, rainwater, or other drainage pipes to facilitate inspection, maintenance, and cleaning. An inspection well is an integral component of drainage systems, effectively improving pipeline maintenance efficiency and safety.
[0003] In recent years, accidents in which pedestrians fall into inspection wells due to slipping have occurred frequently. The measure of installing anti-fall devices at the wellheads of inspection wells has received more and more attention. In the existing technology, the most common method is to install an anti-fall net directly at the wellhead. Since the mesh opening of the anti-fall net is large, it not only cannot prevent bricks, stones and other debris from falling in, but also the anti-fall net will age over time, and its supporting strength will decrease, making it difficult to fully bear the weight of a falling human body, posing a major safety hazard. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides an inspection well with an anti-fall structure, which aims to improve the problem that the anti-fall effect of the inspection well using an anti-fall net will gradually weaken over time.
[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: an inspection well with an anti-fall structure, comprising an inspection well body, a column cavity being opened inside the inspection well body, a manhole cover being provided at the upper part of the inner wall of the inspection well body near the column cavity, a galvanized angle steel being installed at the middle and upper part of the inner wall of the inspection well body near the column cavity, the galvanized angle steel being in an "L" shape, a folded anti-fall grid plate being installed on the upper end surface of the galvanized angle steel, and a lock being provided at the middle part of the upper end surface of the folded anti-fall grid plate.
[0006] Preferably, a pipe is provided on the bottom surface of the inspection well body.
[0007] Preferably, the folded anti-fall grid is arranged at a distance of 300 mm from the upper end surface of the manhole cover.
[0008] Preferably, the diameter of the folded anti-fall grid plate is larger than the diameter of the upper end surface of the column cavity.
[0009] Preferably, a locking page is provided inside the folded anti-fall grid plate.
[0010] The utility model has the following beneficial effects:
[0011] 1. In the utility model, the anti-falling net is replaced by a folded anti-falling grating. Since the folded anti-falling grating is made of strong material, it can withstand greater weight and impact force. The folded anti-falling grating can better protect personnel, and the folded anti-falling grating has good corrosion resistance and durability, and its service life is longer than that of the anti-falling net. The mesh opening of the folded anti-falling grating is smaller than that of the anti-falling net, which can better prevent the falling of debris such as bricks and stones; and the folded anti-falling net can be opened from the middle, which is convenient for maintenance personnel to enter the interior of the inspection well body and inspect the pipeline.

[0016] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] Reference Figure 1-Figure 2The utility model provides an embodiment: an inspection well with an anti-fall structure, including an inspection well body 1, a column cavity 3 is opened inside the inspection well body 1, a manhole cover 2 is arranged on the upper part of the inner wall of the inspection well body 1 near the column cavity 3, and a galvanized angle steel 4 is installed on the middle and upper part of the inner wall of the inspection well body 1 near the column cavity 3. The galvanized angle steel is "L" shaped, and the galvanized angle steel 4 is fixed to the side wall of the inspection well body 1 by expansion screws. This is to make the bearing force on the galvanized angle steel 4 uniform, so that the folded anti-fall grid plate 6 has a certain stability, thereby increasing the safety performance of the anti-fall structure; the upper end surface of the galvanized angle steel 4 is installed with a folded anti-fall grid plate 6, and the folded anti-fall grid plate 6 can open the two folded anti-fall pieces from the middle to It is convenient for maintenance personnel to open the lock on the folded anti-falling grid plate 6 and open the folded anti-falling grid plate 6; the folded anti-falling grid plate 6 is arranged at 300MM from the upper end surface of the manhole cover 2. The purpose of this height is to allow personnel who fall on the folded anti-falling grid plate 6 to call for help, and surrounding personnel can discover it in time without entering the inspection well for rescue, thereby reducing the harm to the rescue personnel; the diameter of the folded anti-falling grid plate 6 is larger than the diameter of the upper end surface of the column cavity 3, and a lock is arranged in the middle of the upper end surface of the folded anti-falling grid plate 6. The lock is to prevent the folded anti-falling grid plate 6 from being opened from the middle, and a locking page is arranged inside the folded anti-falling grid plate 6. The purpose is to increase the stability of the folded anti-falling grid plate 6 and prevent it from moving and deforming under the action of the reverse force.
[0018] Specifically, the folded anti-fall grating 6 is typically made of a sturdy material and can withstand greater weight and impact than an anti-fall net, making it more suitable for protecting heavy objects and personnel. Furthermore, the grating's design makes it less likely to deform when subjected to external forces, providing more reliable protection. Because it is typically made of high-strength steel or aluminum alloy, the folded anti-fall grating 6 has excellent corrosion resistance and durability, maintaining good performance in harsh environments and having a long service life. Furthermore, the folded anti-fall grating 6 has a smaller mesh opening, which further prevents debris such as bricks and stones from falling in.
[0019] Working principle: When a person falls from the wellhead to the inside of the inspection well body 1, the folded anti-fall grid plate 6 can prevent the person from falling to the bottom of the inspection well body 1, thereby protecting the person; when the maintenance personnel need to inspect the pipeline 5, they can unlock the lock on the folded anti-fall grid plate 6, and then open the folded anti-fall grid plate 6 to enter the inside of the inspection well body 1 and inspect the pipeline 5.
[0020] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
