In addition, in order to improve the connection stability of two adjacent strip sensors, the two strip sensors can be fixed at the bottoms of the two adjacent strip sensors through the fixed connecting piece 104, so that the displacement or damage of the connection part of the strip weighing unit in the processes of carrying and installing is avoided. In addition, the bar weighing cell comprises an isolating layer 105, said isolating layer 105 being arranged on the side of the multi-layer structure formed by the bar sensor 101, the sanding assembly 102 and the load-bearing connector 103, as shown in fig. 5. In the process of installing the strip type weighing units, mounting grooves can be excavated in the road surface in advance, and after the strip type weighing units are fixed in the mounting grooves, a fixing agent is poured into other spaces in the mounting grooves, wherein the fixing agent is one of concrete, epoxy resin or grouting material. After the installation is finished, the isolating layer 105 isolates the side faces of the strip sensor 101, the grinding assembly 102 and the bearing connecting piece 103 from the fixing agent, and the strip sensor is prevented from being clamped after the fixing agent is hardened, so that the weighing error is prevented from being enlarged.
