Detailed Description

The utility model is further described below with reference to the accompanying drawings.

Reference is made to the accompanying drawings. The anchor point structure of the utility model comprises an anchor pier 4 and a rubber plug 2. The anchor pier 4 is a concrete pier, and one side of the anchor pier, on which the hanging point anchor cable 1 needs to be installed, is provided with a hanging point anchor cable installation hole 5. In this embodiment, the rubber plug 2 is a single piece and has a symmetrical T-shaped cross section. The rubber stopper 2 includes a cylindrical rubber stopper body 20 and a cylindrical cap 21 attached to one end of the rubber stopper body 20. The rubber plug body 20 is embedded in the mounting hole 5, and the outer side wall is tightly attached to the inner wall of the mounting hole 5. The length of the rubber stopper body 20 may be smaller than the hole depth of the mounting hole 5. The cross section diameter of the cap 21 is larger than that of the mounting hole 5, so that the cap 21 can completely cover the opening of the mounting hole 5 and the surface of the anchor pier 4 around the opening, and the edge of the cap 21 and the edge of the opening of the mounting hole 5 are concentrically distributed after being projected. The rubber plug 2 is provided with a through hole 6, the axis of the through hole 6 coincides with the axis of the rubber plug body 20, the diameter of the through hole 6 is matched with the diameter of the hanging point anchor cable 1, and the hanging point anchor cable 1 is tightly attached to the rubber plug. The end part of the hanging point anchor cable 1 penetrates through the whole rubber plug 2 through the through hole 6, then extends into the mounting hole 5 and is poured and reinforced with the interior of the concrete pier. Therefore, the hanging point anchor cable 1 cannot rub the concrete poured anchoring pier 4 after being shaken by forces in various directions, so that the abrasion of the hanging point anchor cable 1 is reduced; meanwhile, the close fit between the inner wall of the through hole 6 and the hanging point anchor cable 1 also avoids the corrosion of the hanging point anchor cable 1 caused by water flow or impurities entering the channel; in addition, the tight fit between the rubber plug body 20 and the inner wall of the mounting hole 5 also prevents unstable influence on the fixing of the end of the hanging point anchor cable 1 caused by water flow or impurities entering the mounting hole 5.

The rubber stopper cap 21 and the anchoring pier 4 are connected by the connecting piece 3 so as to fix the rubber stopper 2 integrally to the anchoring pier 4. Specifically, the connecting member 3 selected in this embodiment is a combination of a shooting nail and a gasket, the shooting nail penetrates through the cap 21 to enter the anchor pier 4 and is annularly distributed around the orifice of the mounting hole 5, and the gasket is located between the shooting nail and the surface of the cap 21, so that the rubber plug 2 cannot fall off due to the swing of the hanging point anchor cable 1. Of course, the connecting member 3 may be a bolt or the like.

The specific steps of this example are as follows:

step A: firstly, drilling construction is carried out on anchor cables at hanging points, the drilling depth is dozens of meters, and the anchor cables penetrate into bedrock;

and B: after the anchor cable is drilled and formed, hanging point anchor cable lowering construction is carried out, grouting is carried out at the anchoring end, and the tensile force of the anchor cable is tested with equal strength;

and C: after the hanging point anchor cable 1 reaches the strength required by the design, the construction of an anchoring pier 4 at the end part of the hanging point anchor cable can be carried out, the anchoring pier 4 is formed by pouring concrete, and when the concrete is poured, a steel pipe or a PVC pipe is used for protecting the anchor cable to form a mounting hole 5;

step D: after the construction of the anchoring pier 4 is completed, the rubber plug 2 is installed, the anchor cable 1 at the hanging point penetrates through the through hole 6 of the rubber plug 2, after the installation of the rubber plug 2 is completed, the rubber plug 2 is fixed on the anchoring pier 4 by using a shooting nail and a gasket, and the installation of the protection device is completed.

It should be noted that the above describes exemplifying embodiments of the utility model. It will be understood by those skilled in the art, however, that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, but that various changes and modifications may be made without departing from the scope of the utility model as defined by the appended claims.
