specific Embodiment approach 1
[0011] Specific implementation mode one: the following combination figure 1 Describe this embodiment, this embodiment is made up of self-sensing concrete material layer 1, electrode 2 and lead wire 3,
[0012] The self-sensing concrete material layer 1 is embedded with a plurality of electrodes 2, and each electrode 2 is drawn out of the self-sensing concrete material layer 1 through a lead wire 3. The buried depth of the electrodes 2 is greater than 1 cm, and the electrodes 2 are far from the self-sensing concrete material layer 1. Sensing the distance from the bottom surface of the concrete material layer 1 is also greater than 1cm,
[0013] The thickness of the self-sensing concrete material layer 1 is 3cm to 15cm.
[0014] The pavement structure of the road or bridge with self-sensing function described in this embodiment is made of high-sensitivity self-sensing concrete material, which can ensure the monitoring results when the vehicle load is relatively small, and it ca...
specific Embodiment approach 2
[0015] Embodiment 2: This embodiment is a further limitation of Embodiment 1, and the plurality of electrodes 2 are arranged in a distributed or continuous manner. Other components and connections are the same as those in Embodiment 1.
specific Embodiment approach 3
[0016] Embodiment 3: This embodiment is a further limitation of Embodiment 1. The self-sensing concrete material layer 1 is made of nickel powder and cement mixed material, wherein the amount of nickel powder is 1-3 times the mass of cement. Other components and connections are the same as those in Embodiment 1.
