[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a bridge deck waterproof bonding layer interlayer health monitoring system, including an adjustment mechanism 1, which is set inside the main body 2, and a rotation mechanism 3 is set inside the main body 2;

[0023] The adjustment mechanism 1 includes a knob 101, a first gear 102 fixedly connected to the bottom of the knob 101, a number of teeth 103 fixedly connected to the bottom of the first gear 102, a driving bevel gear 104 fixedly connected to the bottom of the first gear 102, two locking blocks 105 fixedly connected to the top of the driving bevel gear 104, locking blocks 105 meshing on the side of the driving bevel gear 104, and a driven bevel gear 107 meshing below the transmission bevel gear 106.

[0024] Several teeth 103 are evenly distributed at the bottom of the first gear disk 102. A locking block 105 is fixedly connected to the bottom of the driven bevel gear 107. The teeth 103 are right-angled triangles. The lower end of the support rod 203 is rotatably connected to the transmission bevel gear 106. The top of the baffle 206 is elastically connected to the inner wall of the adjusting groove 204 through the spring 205. The first gear disk 102 is slidably connected to the adjusting groove 204. The first gear disk 102 is located between the baffle 206 and the second gear disk 207. The teeth 103 at the bottom of the first gear disk 102 are engaged with the second gear disk 207.

[0025] Using the above solution: By embedding sensors 209 between the bridge deck and the pavement layer, the displacement and strain of the pavement layer can be monitored, thereby determining whether the waterproof adhesive layer has failed. Rotating the knob 101 causes the teeth 103 on the first gear plate 102 to rotate along the inclined surface of the second gear plate 207, thereby driving the active bevel gear 104 to rotate. The rotation of the active bevel gear 104 will drive the driven bevel gear 107 to rotate in the opposite direction to the rotation of the active bevel gear 104 through the transmission bevel gear 106, and through the locking block 105, drive the two rotating plates 301 in opposite directions respectively. The device rotates and slides along the sliding groove 208 via the rotating shaft 304. Simultaneously, the rotating shaft 304 drives the driven plate 305 to rotate, thereby causing the movable outer shell 202 to move and unfold away from the main outer shell 201. Then, the knob 101 of the device is moved downwards to above the adhesive layer to complete the adjustment of the device width. This allows it to adapt to different bridge deck widths, ensuring that the sensor's sensing range can cover the entire bridge deck width, achieving comprehensive monitoring, thereby optimizing the monitoring range, ensuring the comprehensiveness and accuracy of monitoring, and improving the flexibility and adaptability of health monitoring between the bridge deck waterproof adhesive layers.

[0026] like Figures 2 to 4 As shown, the inner walls of several movable housings 202 are provided with sliding grooves 208. Sensors 209 are fixedly connected to the bottom of the main housing 201 and the movable housings 202. The lower end of the support rod 203 is rotatably connected to the transmission bevel gear 106. The top of the baffle 206 is elastically connected to the inner wall of the adjustment groove 204 through a spring 205. The first gear 102 is slidably connected to the adjustment groove 204. The first gear 102 is located between the baffle 206 and the second gear 207. The teeth 103 at the bottom of the first gear 102 are engaged with the second gear 207.

[0027] The rotating mechanism 3 includes two rotating plates 301. The top of the rotating plate 301 is provided with a slot 302 and the bottom of the rotating plate 301 is provided with a rotating groove 303. The two ends of the rotating plate 301 are rotatably connected to the driven plate 305 through a rotating shaft 304. There are several driven plates 305. The rotating shaft 304 is slidably connected to the slide groove 208. The two rotating plates 301 are symmetrically distributed with the transmission bevel gear 106 as the center. The locking block 105 is locked with the slot 302, and the driving bevel gear 104 is slidably connected to the rotating groove 303.

[0028] The working principle and usage process of this utility model are as follows: First, a waterproof material, such as modified asphalt, polyurethane, epoxy resin, etc., is evenly applied to a clean bridge deck. These materials have good waterproof performance and adhesion to the bridge deck. Then, an adhesive layer is applied on top of the waterproof layer to form a waterproof adhesive layer. Subsequently, according to the width of the bridge deck, the knob 101 is rotated to make the teeth 103 on the first gear plate 102 rotate along the inclined surface of the second gear plate 207, thereby driving the active bevel gear 104 to rotate. The rotation of the active bevel gear 104 will drive the driven bevel gear 107 to rotate in the opposite direction to the rotation direction of the active bevel gear 104 through the transmission bevel gear 106. The two rotating plates 301 are driven to rotate in opposite directions through the locking block 105, and slide on the slide groove 208 through the rotating shaft 304. At the same time, the rotating shaft 304 drives the two rotating plates 301 to rotate in opposite directions. The driven plate 305 rotates, causing the movable outer shell 202 to move away from the main outer shell 201 and unfold, so that the movable outer shells 202 on both sides of the device abut against the sides of the bridge deck. Then, the knob 101 of the device is moved downwards to above the adhesive layer to complete the adjustment of the width of the device. It can adapt to the width of different bridge decks and can be adjusted according to the actual width of the bridge to ensure that the sensing range of the sensor can cover the entire width of the bridge deck, realize comprehensive monitoring, optimize the monitoring range, ensure the comprehensiveness and accuracy of monitoring, and improve the flexibility and adaptability of the health monitoring between the waterproof adhesive layers of the bridge deck. Finally, the bridge deck is paved so that the sensor 209 abuts against the paving layer. The sensor is embedded between the bridge deck and the paving layer to monitor the displacement and strain of the paving layer, thereby determining whether the waterproof adhesive layer has failed.
