Description

Technical Field

[0001] This utility model relates to the field of anchor cable construction monitoring, specifically to an anti-corrosion anchor cable for coastal environments. Background Technology

[0002] Traditional anchor cable materials are only suitable for ordinary strata. However, in coastal strata, the high salinity and high humidity of the seawater accelerate the corrosion process of anchor cables, leading to surface rust, reduced strength, and even breakage. This makes it difficult to maintain their original mechanical properties and structural integrity for extended periods, thus affecting their service life and safety, and failing to meet the high requirements of near-shore engineering for anchor cable support. Therefore, it is necessary to monitor the corrosion level of the anchor cable body in real time to avoid problems caused by severe corrosion leading to a significant reduction in mechanical properties, structure, and strength.

[0003] In existing technologies, anchor cables are protected against corrosion by simply applying an anti-corrosion coating to the surface. After a period of use, fine cracks easily appear, allowing seawater or salt water to seep in and corrode the anchor cable. Furthermore, since the anchor cable is driven into the soil, monitoring the degree of corrosion during its use is extremely difficult. Therefore, this paper proposes an anti-corrosion anchor cable that can effectively prevent salt water / seawater corrosion and simultaneously enable rapid corrosion monitoring of the anchor cable itself. Utility Model Content

[0004] The purpose of this invention is to provide a corrosion-resistant anchor cable for coastal environments, in order to solve the problem that anchor cables are easily corroded by salt water / seawater in the surrounding coastal environment, and the problem that it is difficult to monitor the corrosion of anchor cables in such environments.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A corrosion-resistant anchor cable for coastal environments includes:

[0007] The first anti-corrosion coating is applied to the exterior of the anchor cable body;

[0008] A thin film layer, covering the outside of the first anti-corrosion coating;

[0009] The second anti-corrosion coating is applied to the outside of the thin film layer;

[0010] A sealing sleeve is fitted over the second anti-corrosion coating;

[0011] It also includes a multi-probe corrosion sensor, with multiple multi-probe corrosion sensors evenly distributed inside the first anti-corrosion coating along the axial direction of the anchor cable body and closely attached to the anchor cable body.

[0012] The reference electrode is located at the end of the anchor cable body, within the first anti-corrosion coating, and is also in close contact with the anchor cable body.

[0013] Specifically, both the first and second anti-corrosion coatings are epoxy-based anti-corrosion coatings.

[0014] Specifically, the film layer is a polyethylene film layer.

[0015] Specifically, the multiple multi-probe corrosion sensors are divided into two sensor groups, which are respectively installed on the outer walls of both sides of the anchor cable body.

[0016] Specifically, the sealing sleeve is an elastic sleeve.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] This invention provides multi-layer protection for the anchor cable body by sandwiching a thin film layer between a first anti-corrosion coating and a second anti-corrosion coating. This effectively isolates the anchor cable body from external salt and moisture, preventing rust and corrosion. Furthermore, it uses two sensor groups of a multi-probe corrosion sensor to monitor the potential at various points on the anchor cable and compares it with the potential at the location of a reference electrode that will not corrode. This achieves the purpose of detecting the rust on the anchor cable body, effectively simplifying the anchor cable body monitoring process and facilitating timely understanding of the real-time status of the anchor cable body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0023] like Figure 1 and Figure 2 As shown, a corrosion-resistant anchor cable for coastal environments includes:

[0024] The first anti-corrosion coating 1 is applied to the exterior of the anchor cable body 6;

[0025] Thin film layer 2, covering the outside of the first anti-corrosion coating 1;

[0026] The second anti-corrosion coating 3 is applied to the outside of the thin film layer 2;

[0027] The sealing sleeve 4 is fitted over the second anti-corrosion coating 3;

[0028] It also includes a multi-probe corrosion sensor 5, which is evenly distributed inside the first anti-corrosion coating 1 along the axial direction of the anchor cable body 6 and is closely attached to the anchor cable body 6.

[0029] The reference electrode 7 is located at the end of the anchor cable body 6, inside the first anti-corrosion coating 1, and is also in close contact with the anchor cable body 6.

[0030] In this invention, when processing the anchor cable body 6, a combination of mechanical grinding and chemical cleaning is first used to perform a comprehensive and meticulous pretreatment operation to remove rust and oil from the anchor cable body 6. This thoroughly removes the rust layer and oil stains from the surface of the anchor cable body 6, ensuring effective adhesion of the subsequent first anti-corrosion coating 1. Then, a multi-probe corrosion sensor and a reference electrode 7 are installed on the outer surface of the pretreated anchor cable body 6. The multi-probe corrosion sensor can be a CorroWatch multi-probe corrosion sensor manufactured by Force in Denmark, and the reference electrode 7 is generally an ERE20 reference electrode from the same company. Multiple multi-probe corrosion sensors 5 are evenly distributed on the outer wall of the anchor cable body 6 along the axial direction of the anchor cable body 6, with a certain interval between each multi-probe corrosion sensor 5. When installing the sealing sleeve 4 later, the multi-probe corrosion sensors 5 are tightly fitted to the anchor cable body 6, and the reference electrode 7 is placed as close as possible to the end of the anchor cable body 6, with the conductive lines aligned and arranged along the anchor cable. After installing the multi-probe corrosion sensor 5, a layer of anti-corrosion coating is uniformly applied to the outside of the anchor cable body 6 as the first anti-corrosion coating 1. During the application process, the coating thickness must be controlled to ensure uniformity and avoid missed areas or overlapping. After this treatment, a preliminary anti-corrosion barrier is formed on the outer surface of the anchor cable body 6, effectively resisting the erosion of salt and moisture. Immediately afterwards, a thin film is tightly wrapped around the outer surface of the first anti-corrosion coating 1 as the film layer 2. During wrapping, it should be ensured that there are no air bubbles or wrinkles between the film and the first anti-corrosion coating 1 to guarantee the sealing effect of the film layer 2. After the film layer 2 is applied, the anchor cable body 6 not only isolates external moisture but also protects the inner first anti-corrosion coating 1 from damage. After the film layer 2 completely covers the outer surface of the first anti-corrosion coating 1, anti-corrosion coating is applied again uniformly. This repeated application further enhances the anti-corrosion effect, forming a more robust second anti-corrosion coating 3, thereby effectively isolating the anchor cable body 6 from the influence of external moisture and saltwater environment.

[0031] In a preferred embodiment, both the first anti-corrosion coating 1 and the second anti-corrosion coating 3 are epoxy-based anti-corrosion coatings.

[0032] In this embodiment, an alternative implementation of the first anti-corrosion coating 1 and the second anti-corrosion coating 3 is provided. Epoxy anti-corrosion coatings are a type of coating with epoxy resin and modified epoxy resin as the main film-forming substances. They have excellent adhesion, chemical corrosion resistance, good alkali resistance, and a hard coating. They can effectively cover the multi-probe anti-corrosion sensor 5 and the anchor cable body, and effectively prevent damage caused by covering the multi-probe anti-corrosion sensor 5 while isolating external moisture.

[0033] In a preferred embodiment, the film layer 2 is a polyethylene film layer.

[0034] Polyethylene film has high air permeability, and its air permeability decreases with increasing density. At the same time, due to its moisture-proof properties and low moisture permeability, it can effectively isolate and protect the internal first anti-corrosion coating 1.

[0035] In a preferred embodiment, the multiple multi-probe corrosion sensors 5 are divided into two sensor groups, which are respectively set on the outer walls of both sides of the anchor cable body 6.

[0036] like Figure 2 As shown, in this embodiment, by dividing the multi-probe corrosion sensor 5 into two groups and symmetrically arranging them on both outer walls of the anchor cable body 6, the detection area of ​​the multi-probe corrosion sensor 5 can cover the entire outer area of ​​the anchor cable body 6 as much as possible, thereby effectively improving the detection accuracy of the multi-probe corrosion sensor 5.

[0037] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the sealing sleeve 4 is an elastic sleeve.

[0038] In this embodiment, by selecting an elastic sleeve for the sealing sleeve 4, the tight contact between the sealing sleeve 4 and the second anti-corrosion coating 3 can be effectively ensured, preventing moisture from seeping in through the gap between them. At the same time, it can also prevent the first anti-corrosion coating 1 and the second anti-corrosion coating 3 from being scratched during subsequent construction, thus achieving double protection.

[0039] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection.
