[0034] The supporting sealing assembly 1 comprises an upper supporting plate 11 , and a sealing rubber pad 12 is fixedly connected to the bottom of the upper supporting plate 11 .

[0035] The upper support plate 11 and the sealing rubber pad 12 have the same shape, size and material, and are made of stainless steel, which has good corrosion resistance and good strength and hardness.

[0036] The bottom of the connection groove 21 is fixedly connected with the lower support plate 13 . The connection groove 21 is opened on the bottom surface of the upper support plate 11 and the top surface of the lower support plate 13 .

[0037] The sealing rubber pad 12 is in a ring shape, and the upper support plate 11 and the sealing rubber pad 12 are fixedly connected by the sealing rubber pad 12 , which has good shock absorption and sealing properties.

[0038] The connecting assembly 3 includes a connecting hole 31 , which is opened inside the center of the upper support plate 11 and the sealing rubber pad 12 , and a sealing ring 32 is fixedly installed inside the connecting hole 31 .

[0039] There are two connecting components 3, and two connecting holes 31 are respectively opened inside the center of the upper support plate 11 and the lower support plate 13, and are connected to the inside of the connecting groove 21. Two sealing rings 32 are fixedly connected to the inside of the two connecting holes 31, and have the function of sealing to prevent water from entering the inside of the connecting groove 21. The steel bar 4 passes through the two connecting holes 31 and the inside of the connecting groove 21, so as to fix the device on the outer surface of the steel bar 4.

[0040] The monitoring component 5 includes a corrosion detection sensor 51 , which is fixedly installed inside the connection groove 21 , and the corrosion detection sensor 51 is fixedly connected to the outer surface of the steel bar 4 .

[0041] The corrosion detection sensor 51 is fixedly connected to the outer surface of the steel bar 4 embedded in the connecting groove 21, and the corrosion of the steel bar 4 is detected using the half-cell method. The half-cell potential method uses the potential change caused by the electrochemical reaction of the corrosion of the steel bar 4 in the concrete to determine the corrosion state of the steel bar 4.

[0043] The pressure sensor 52 can monitor the pressure on the concrete in real time. Its working principle is to form a semiconductor deformation pressure on the surface of the thin film, and to deform the thin film through external force (pressure) to produce a piezoelectric impedance effect, thereby converting the impedance change into an electrical signal. The humidity sensor 53 has four probes, which are fixedly installed on the left and right ends of the upper support plate 11 and the lower support plate 13. It is used to detect the permeability of concrete. If the permeability of concrete is strong, it is very easy to cause a large amount of water to penetrate into the concrete, which will cause corrosion of the steel bars over a long period of time, thereby affecting the service life of the steel bars. Its working principle is to cover a layer of film made of humidity-sensitive material on the substrate. When water vapor in the air is adsorbed on the humidity-sensitive film, the resistivity and resistance value of the element change. This feature can be used to measure humidity.

[0045] First, the connecting hole 31 is drilled on the outer surface of the steel bar 4, and the elastic force of the sealing ring 32 seals the connection between the connecting hole 31 and the steel bar 4. The supporting sealing component 1 is fixed on the outer surface of the steel bar 4, and then poured. The device is buried in the interior of the concrete. When the concrete is subjected to greater pressure and vibration, the elastic force of the spring in the shock absorbing component 2 cooperates with the damper to reduce shock, thereby reducing the vibration of the supporting sealing component 1. The corrosion detection sensor 51 can monitor the corrosion of the steel bar 4, the pressure sensor 52 detects the bearing pressure of the concrete, and the humidity sensor 53 detects the water permeability of the concrete.

[0046] Compared with the related art, the embedded concrete durability monitoring sensor device provided by the utility model has the following beneficial effects:
