Abstract

The danger is even greater if a leaking pole is encountered on a rainy day or on a slippery surface. Therefore, it is necessary to develop methods to improve the corrosion resistance of cement concrete poles. Utility Model Content

[0021] Example
[0022] Reference Figure 1 The present invention proposes a corrosion-resistant concrete pole, comprising: a steel reinforcement cage 10; the steel reinforcement cage 10 includes a steel cage assembly 11 extending longitudinally along the pole and several longitudinal steel bars 12; the several longitudinal steel bars 12 are distributed circumferentially, and the steel cage assembly 11 is wound around the several longitudinal steel bars 12; a concrete layer 20 is formed by pouring concrete into the steel reinforcement cage 10; an anti-corrosion insulation layer 30 is provided on the inner and outer sides of the concrete layer 20; anchor bars 13 are provided on both sides of the longitudinal steel bars 12 along the radial direction, and the anchor bars 13 can extend into the inner and outer anti-corrosion insulation layer 30.
[0023] In this utility model, anchor bars 13 are provided on both sides of the longitudinal steel bar 12 along the radial direction, which can extend into the anti-corrosion insulation layer 30 on both sides of the concrete layer for fixing and reinforcement; the anti-corrosion insulation layer 30 is made of silicone rubber and other materials, which can provide effective protection against damage and leakage from the inside and outside of the concrete layer 20. The pole as a whole has strong structural support and effective corrosion resistance.
[0024] In this embodiment, several protrusions 21 are integrally cast on the inner and outer surfaces of the concrete layer 20. These protrusions 21 increase the contact area between the concrete layer 20 and the corrosion-resistant insulating layer 30, making the combination of layers more reliable and stable.
[0025] In this embodiment, a plurality of anchors 40 are provided on the anti-corrosion insulation layer 30 on the outside of the concrete layer 20. The anchors 40 are provided with anchor caps 41 and anchor posts 42. The anchor posts 42 pass through the outer anti-corrosion insulation layer 30 and partially extend into the concrete layer 20. Specifically, during prefabrication, the anchor seats corresponding to the anchors 40 are prefabricated integrally when the concrete layer 20 is poured. Then, the anti-corrosion insulation layer 30 is coated / poured on both the inner and outer sides of the concrete layer 20 to form a structure in which the anti-corrosion insulation layer 30 covers the anchor seats. After the anti-corrosion insulation layer 30 is formed, the anchors 40 can be locked.
[0026] In this embodiment, to prevent interference between the anchor 40 and the anchoring rib 13, the anchor 40 and the anchoring rib 13 are arranged in a staggered manner. Specifically, the anchor 40 and the anchoring rib 13 are distributed in staggered layers; or, the anchor 40 and the anchoring rib 13 are distributed at an angle.
[0027] In this embodiment, the concrete layer 20 includes alkali slag fly ash concrete, which includes fly ash, slag powder, alkaline activator, fine aggregate, coarse aggregate and water.
[0028] Alkali-slag-fly ash concrete is an alkaline activated concrete composed of a large amount of fly ash, slag and other industrial waste, alkaline activator, special admixtures and sand and gravel aggregates. Unlike ordinary cement concrete, it has strong resistance to salt, acid and alkali corrosion.
[0029] Alkaline activators are compounds primarily composed of alkali metals that can activate the potential activity of materials such as fly ash and slag powder. Alkaline slag-fly ash corrosion-resistant cementitious materials, mainly composed of fly ash and slag powder, form a calcium-aluminum-silica system cementitious material under the action of alkaline activators. This cementitious material possesses certain physical and mechanical properties and exhibits superior chemical corrosion resistance compared to silicate cementitious materials. Furthermore, admixtures and other additives are required.
[0030] In this embodiment, the corrosion-resistant insulating layer 30 is a silicone rubber high-voltage insulating layer.
[0031] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
