[0038] The working process of the road bridge water seepage detection device is as follows:

[0039] First, select a detection point, select a section of flat road surface, and then place the device on the road surface. The conical design at the bottom of the anchor rod 102 can be inserted into the surface of soft roads such as asphalt to achieve a fixing effect. Then start the motor 202. The motor 202 drives the gear 2 301 to rotate through the gear 1 203 and the transmission gear inside the device body 100, thereby driving each group of slotting cylinders 300 to rotate at the same time. The device body 100 is further pushed toward the road surface through the handle on the top of the device body 100. The device body 100 slides along the outer wall of the anchor rod 102 and moves toward the road surface. When the slotting cylinder 300 contacts the road surface, the serrations at the bottom of the slotting cylinder 300 open the road surface. Through the chamfered angle design at the bottom of the slotting cylinder 300 and the spiral chip removal groove design of the slotting cylinder 300, the debris generated by the opening is guided by the bottom of the slotting cylinder 300 and discharged to the outside of the slotting cylinder 300 through the chip removal groove, reducing The probability of impurities entering the slotted barrel 300 is reduced, and the influence of debris on the sealing and detection effect is reduced. Furthermore, the device body 100 continues to be pushed toward the road surface. Through the positioning and guidance of the anchor rod 102, it can be ensured that the device body 100 and the slotted barrel 300 are opened toward the inside of the road surface in the vertical direction. At the same time, through the buffering of the support spring 104, it is ensured that the device body 100 moves slowly and steadily during the opening, and the quality of the opening is improved. When the device body 100 moves down to completely expose the external thread of the anchor rod 102, the motor 202 is stopped at this time, and then the thread block 106 is tightened and rotated to the lowest point of the external thread of the anchor rod 102, so that it cooperates with the thread of the outer wall of the anchor rod 102, and the device body 100 is pushed toward the ground by a specified distance. At the same time, the device body 100 is fixed at the specified position of the outer wall of the anchor rod 102 to prevent the device body 100 from rebounding.

[0040] Further, the motor 1 201 is started, and the motor 1 201 rotates to drive the threaded barrel 200 to rotate. When the threaded barrel 200 rotates, the rotating ring 1 204 is driven to move upward through the thread transmission, and the rotating shaft 105 is driven to rotate through the pin 1 205. When the rotating shaft 105 rotates, the end connected to the pin 1 205 is lifted, and the end of the rotating shaft 105 that moves with the pin 2 312 sinks, pushing the rotating ring 2 311 to drive the sleeve 302 to move downward. During the downward movement of the sleeve 302, the sealing ring 311 at the bottom of the sleeve 302 is driven. 07 moves down and contacts the road surface. As the sleeve 302 continues to move down, the spring between the sealing ring 307 and the sleeve 302 is compressed. At the same time, the rubber gasket at the bottom of the sealing ring 307 fits tightly against the road surface to seal the gap. During the downward movement of the sleeve 302, the waterproof sealant liquid stored in the sealing groove 2 304 can be squeezed into the sealing groove 1 303 through the one-way valve on the sealing ring 306 through the downward movement of the piston ring 308, so as to fill and seal the gap between the sealing groove 1 303 and the road surface. Figure 6At this time, the slotted cylinder 300 goes deep into the road surface and cuts a group of cylindrical test bodies from the road surface to simulate the laboratory water seepage detection test. At the same time, the waterproof glue fills the inside of the sealing groove 303, so that the outer wall of the cut cylindrical road surface test body is wrapped and covered by the waterproof glue, so as to avoid the flow of water from the gap between the road surface test body and the inner wall of the slotted cylinder 300 during the test to affect the detection result. In addition, through the compression and blocking of the sealing rubber gasket at the bottom of the sealing ring 307, the waterproof glue with lower fluidity than water is difficult to or only a small amount of leakage from the gap of the rubber gasket, so as to ensure that the glue is filled and distributed inside the sealing groove 303, reduce the glue from penetrating into the inside of the slotted cylinder 300 above the road surface being tested to affect the passage of liquid, ensure the full contact and penetration of the top of the road surface being tested with the water flow, and improve the accuracy of the detection.

[0041] After the waterproof glue solidifies, the waterproof glue inside the sealing groove 303 solidifies, and the side walls of the cylindrical test body of the road surface to be tested are wrapped by the waterproof glue, filling the gaps and holes in the side walls. The top of the cylindrical test body is connected to the sleeve 302. At this time, the pump liquid pipe and the pump air pipe on the liquid storage chamber 101 are connected to the liquid inlet 309 and the air inlet 310 respectively. After a specified amount of liquid is pumped into the sleeve 302 through the liquid inlet 309, a certain gas pressure is applied to the inside of the sleeve 302 through the air inlet 310. The top of the cylindrical test body inside the sleeve 302 contacts the liquid inside the sleeve 302, and the water flows in from the top of the cylindrical test body and starts to penetrate. By observing the scale on the side wall of the sleeve 302, the penetration index is obtained. Compared with traditional drilling or straight In connection with road surface testing, the device simultaneously drills annular holes and grooves on the road surface through multiple groups of slotting cylinders 300, divides the road surface into cylindrical test bodies, realizes multiple groups of sampling and testing in the same area at the same time, greatly improves the testing efficiency, and the slotting materials can be automatically discharged through the chamfer at the bottom of the slotting cylinder 300 and the spiral chip removal groove during slotting, reducing the cleaning process, and the opening of the annular holes and grooves causes little damage to the road surface, and the backfill repair cost is low. During the test, the top of the test body is closed and sealed by pressing down the sleeve 302, and the glue stored in the sealing groove 2 304 is squeezed into the sealing groove 1 303 for uniform distribution, and the side wall of the test block is wrapped and sealed to prevent water from penetrating from the edge of the test area during the test, thereby ensuring the accuracy of the test result.

[0042] After the detection is completed, the motor 201 rotates in the opposite direction when the device is reset, and the sleeve 302 can be lifted up by the rotation of the rotating shaft 105. When the sleeve 302 rises, the sealing ring 307 is reset and popped out under the action of the spring force of the sleeve 302. During the rising and resetting process of the sleeve 302, the piston ring 308 moves up, so that the internal pressure of the cavity surrounded by the sealing ring 307 and the sealing groove 2 304 becomes lower, and the glue inside the storage chamber 305 is sucked in again, automatically preparing for the next sampling work, ensuring the continuity of the detection work and reducing labor costs.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
