Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

In the description of this patent, it should be noted that, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "disposed" are to be construed broadly, and may be fixedly connected, disposed, detachably connected, disposed, or integrally connected, disposed, for example. The specific meaning of the terms in this patent will be understood by those of ordinary skill in the art as the case may be.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 1-3, an anti-falling structure for an inspection well is shown, which comprises an inspection well 1, a concrete pouring section 8 arranged above the inspection well, a support 5 arranged at the top of the concrete pouring section, a hook 3 arranged on the support and a well cover 2 arranged on the support; an anti-falling net 7 is arranged above the inspection well; the anti-falling net 7 is connected with the support 5 by using hooks 3.

FIG. 3 shows the mount without the hooks installed; the support comprises an annular support body 54, an annular fixing sheet 52 arranged at the periphery of the bottom of the support body and perpendicular to the support body, and a well lid limiting ring 53 arranged at the periphery of the top of the support body; the well lid limiting ring is connected with the support body by using an angular connecting piece 55. The boss 51 formed at the top of the support body is used for placing the well lid 2. At this time, the well lid can be directly placed on the support body; the well lid limiting ring can be movably connected with the well lid, for example, the well lid limiting ring is hinged, so that the well lid can be prevented from being lost to a certain extent by the design, and the well lid can be conveniently opened and closed.

The hooks can be uniformly distributed on the inner side of the support body. As a preferred form of this embodiment, the hooks are 8 hooks uniformly welded to the support body.

The specific embodiment of the utility model comprises the following steps:

(1) Processing and manufacturing the support;

(2) After the support is manufactured, a plurality of hooks are uniformly welded on the inner side of the support body. For example 8;

(3) After the hanger is welded, the hanger and the support are preserved, and the service life of the hanger is prolonged;

(4) After the safety of the on-site inspection well is finished, the anti-falling net 7 is tied on the hook 3, so that the installation of the anti-falling net 7 can be finished;

(5) After the anti-falling net is installed, the well lid is buckled.

The foregoing is merely exemplary of the present utility model, and those skilled in the art should not be considered as limiting the utility model, since modifications may be made in the specific embodiments and application scope of the utility model in light of the teachings of the present utility model.
