Embodiment Construction

[0035] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0036] like Figure 1~3 As shown, the present invention is provided with 4 reinforced sheet anodes 1, 4 316L stainless steel sheet cathodes 2, 4 polyoxymethylene hollow rods 3, 1 polyoxymethylene base 5 and 1 eight-core wire 6. The steel sheet serves as the anode, and the 316L stainless steel sheet serves as the cathode, forming 4 pairs of galvanic couples with different heights. Each pair of galvanic couples is connected by a corresponding wire 6. The anode 1 of the steel sheet and the cathode 2 of the stainless steel sheet are kept parallel in the horizontal direction. In the vertical direction, the fixed difference is 12mm. The anodes 1 of the four reinforcement sheets are 5mm apart in the vertical direction. The connection of the whole sensor, such as steel sheet anode 1 and polyformaldehyde hollow rod 3, stainless steel sheet cathode 2 and poly...

Abstract

The invention relates to a sensor, in particular to a reinforced concrete embedded type corrosion sensor. The invention provides the reinforced concrete embedded type corrosion sensor which is provided with four pairs of corrosion galvanic couples, a hollow bar, a base and a connecting lead, wherein the corrosion galvanic couple consists of an anode and a cathode, and is fixed on the hollow bar; the hollow bar is fixed on the base; the lead firstly passes through a thread hole of the hollow bar, and then is led out from a groove of the base; and the hollow bar and the base are embedded and filled by epoxy resin. The reinforced concrete embedded type corrosion sensor has small volume, thus having less influence on concrete structure; the structure is simple and firm, so that the corrosion sensor can not be washed away when pouring concrete; the processing is convenient, and the cost-performance ratio is high; the materials are easy to obtain; the corrosion sensor is installed in the concrete before pouring the concrete, so that the corrosion sensor can conduct long-term monitoring on reinforced concrete structure from early stage, and monitoring environment is the same as reinforced concrete environment; the area ratio and distance between the anode and the cathode can be determined and adjusted according to needs or specific experiment tests; and the corrosion sensor can be installed at a pre-monitoring point and an important cross section according to the needs, with convenient installation and operation.

Description

technical field [0001] The invention relates to a sensor, in particular to a reinforced concrete embedded corrosion sensor. Background technique [0002] In various large-scale engineering structures, such as ground construction engineering, bridge engineering, foundation engineering, tunnel engineering, dams, subways, mines, etc., the harm caused by the corrosion of steel bars in concrete is a major concern worldwide. . The deterioration of the concrete material itself and the corrosion of the steel bars jointly affect the durability of the concrete structure, threatening the safety and reliability of the entire project. Among them, the corrosion of the steel bar is the most important factor affecting the durability and service life of the reinforced concrete structure. Therefore, it is necessary to develop real-time monitoring and detection technology for steel corrosion, improve the accuracy and work efficiency of steel corrosion degree and corrosion speed detection in c...
