Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments 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.
This embodiment provides a pole root protector, mainly twines the root at the pole, and protector part buries underground, and part extends the earth's surface, prevents that soil from causing the corruption to the outer concrete of pole and the inside reinforcing bar of pole, improves the life of pole.
As shown in fig. 1 and 2, the pole protection device comprises a protection layer 1 which is mainly installed at the root of a pole 2.
Specifically, the protective layer 1 is spirally wound upwards around the axis of the electric pole 2 from the root of the electric pole 2, so that the protective layers 1 of two adjacent turns overlap each other to form a lamination area 101, as shown in fig. 4, to prevent the outer wall of the root of the electric pole 2 from being exposed to the external environment.
The pole root that twines inoxidizing coating 1 buries in the soil downside, utilizes inoxidizing coating 1 to separate external soil and the body of pole 2, prevents that the pH valve of soil from causing the corruption to the outer wall of pole or the reinforcing bar of pole inside, can prolong the life of pole.
Specifically, in this embodiment, as shown in fig. 3, the protective layer 1 is made of a plurality of glass fibers 11 and an adhesive 12 that are arranged in parallel, and the corrosion of the soil to the electric pole is prevented by using good corrosion resistance, alkali resistance, and the like of the glass fibers 11.
In this embodiment, since a part of the protective layer 1 wound around the root of the pole 2 is located outside the soil, the adhesive 12 is made of polyurethane resin in order to reduce damage to the pole caused by uv light.
Specifically, in this embodiment, taking an 18-meter electric pole as an example, according to national standard requirements, the length of the electric pole pre-buried under the soil is 3 meters, and therefore, the winding height of the protective layer 1 needs to be set to 4.5 meters, so that the protective layer 1 exposed out of the ground surface has a height of 1.5 meters, and corrosion of the outer wall of the electric pole 2 caused by splashing of the soil onto the electric pole 2 due to rainwater is prevented.
The winding height of the protective layer 1 is increased by 1m-1.5m on the basis of the depth of the electric pole 2 buried under the ground, only the root of the electric pole 2 is wound, the consumption of glass fiber 11 is reduced, and the production cost of the electric pole 2 is reduced on the basis of not changing the preparation process of the concrete electric pole.
The width of the protective layer 1 is 190mm-250mm, in this embodiment, the width of the selected protective layer 1 is 220mm, wherein the width of the lamination area 101 overlapped by two adjacent circles of protective layers 1 is 10mm-15mm, so that gaps between the two adjacent circles of protective layers 1 are prevented, in this embodiment, the lamination width of the lamination area 101 is 12mm, and external rainwater flows onto the outer wall of the electric pole 2 along the gaps.
In order to wind the protective layer 1 at the root of the electric pole 2, a plurality of glass fibers 11 are arranged in parallel, gaps between the two glass fibers 11 are reduced as much as possible, polyurethane resin is uniformly coated on the inner side and the outer side of the glass fibers 11, and then the glass fibers 11 immersed in the polyurethane resin are spirally wound at the root of the electric pole 2 by using a winding machine, wherein the polyurethane resin plays a role in adhesion and shaping, and meanwhile, the protective layer 1 formed by the glass fibers 11 can be adhered to the outer wall of the electric pole 2, so that corrosion of soil to the electric pole and steel bars inside the electric pole is prevented, and the service life of the electric pole 2 is prolonged.
The adhesive 12 is selected as polyurethane resin here, and the ultraviolet resistance of the electric pole is enhanced in consideration of the excellent ultraviolet resistance of the polyurethane resin.
