The salinity detection probe is equipped with multiple detection rods, and the detection display and the salinity detection probe are connected via a transmission line. A cleaning component is included to automatically clean the soil adhering to the surface of the detection rods after testing. The aforementioned document describes the use of the detection display and salinity detection probe in conjunction to detect soil surface conditions. This same device is also used on asphalt roads. However, the width and length of asphalt roads require operators to constantly adjust the position of the detection display and salinity detection probe, increasing the operator's workload. Furthermore, moving the handheld detection element compromises its stability. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 A dynamic detection device for surface salt content of asphalt pavement in saline areas includes a support 1 installed on both sides of the road. The support 1 is equipped with a smoothness meter 2 and an ultrasonic testing head 3 for detecting the surface salt content of the asphalt pavement. The smoothness meter 2 can measure the smoothness of the asphalt pavement, and the ultrasonic testing head 3 can detect the thickness of the asphalt pavement. The impact of salt content on the pavement structure can be determined based on the test results. The smoothness meter 2 and the ultrasonic testing head 3 can be disassembled for protection.

[0017] A plug post 9 extending into the ground is fixedly installed on the bracket 1. A slider 5 is slidably fitted inside the bracket 1. A limit groove 11 is formed on one end of the bracket 1, and a limit rod 12 is fixedly installed on the other end of the bracket 1. (Supplementary notes are attached to the instruction manual.) Figure 1 As shown, when the two sets of brackets 1 are spliced, the limiting rod 12 on the second set of brackets 1 extends into the limiting groove 11 inside the first set of brackets 1, so that the two sets of brackets 1 can be spliced, thereby enabling the detection of asphalt roads of different lengths.

[0018] The bracket 1 has a concave structure, and a positioning strip 4 that cooperates with the slider 5 is integrally connected to the bracket 1. A level 10 is fixedly installed on the bracket 1, and a handrail is fixedly installed on the sleeve 6. The slider 5 has a positioning hole for positioning the positioning strip 4. The bracket 1 and the positioning strip 4 can guide the slider 5. By setting the level 10 on the bracket 1, the level 10 can check the balance of the bracket 1.

[0019] Sleeves 6 are placed inside two supports 1, and displacement rods 7 are slidably fitted inside the sleeves 6. The sleeves 6 are horizontally positioned on both sides of the support 1. The sleeves 6 have clamp grooves 13 for guiding the displacement rods 7. The flatness instrument 2 is mounted on the sleeves 6. The clamp grooves 13 guide the displacement rods 7, and when the two displacement rods 7 move in opposite directions, the distance between the two displacement rods 7 can be adjusted, so that the support 1 as a whole can inspect asphalt pavements of different widths.

[0020] An installation rod 8 is connected between the displacement rod 7 and the slider 5. The ultrasonic detection head 3 is mounted on the installation rod 8. The installation rod 8 is horizontally positioned between the displacement rod 7 and the slider 5. By removing the installation rod 8 from the slider 5 and the displacement rod 7, the bracket 1, sleeve 6, and installation rod 8 can be disassembled as a whole, thus reducing the floor space occupied.

[0021] The mounting rod 8 has connecting ears that extend to the displacement rod 7 and the slider 5, and the connecting ears are threaded with fixing bolts that connect to the displacement rod 7 and the slider 5. The sleeve 6 is provided with a clamping structure for clamping the displacement rod 7.

[0022] The clamp structure includes a cylinder 14 and a mounting base 15 fixedly installed on the sleeve 6. The displacement rod 7 has evenly distributed positioning grooves 16. The mounting base 15 is equipped with a plate 18, and a positioning rod 17 that passes through the positioning groove 16 and extends into the cylinder 14 is fixedly installed on the plate 18. By having evenly distributed positioning grooves 16 on the displacement rod 7, when the displacement rod 7 extends out of the sleeve 6, the positioning rod 17 can cooperate with one of the positioning grooves 16.

[0023] The plate 18 and the positioning rod 17 extend to the upper end of the mounting base 15, and an extension column 20 extending into the mounting base 15 is fixedly installed on the plate 18. A clamping plate 19 for limiting the positioning rod 17 is fixedly installed on the cylinder 14. The clamping plate 19 is an arc-shaped structure adapted to the positioning rod 17. By setting the clamping plate 19 to an arc-shaped structure adapted to the positioning rod 17, the contact area between the clamping plate 19 and the positioning rod 17 can be increased. After the clamping plate 19 clamps the lower end of the positioning rod 17, it can clamp the moved displacement rod 7, thereby locking the sleeve 6 and the displacement rod 7.

[0024] It should be noted that the specific models and specifications of the flatness tester 2, ultrasonic testing head 3, and level 10 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, so they will not be elaborated here.

[0025] The functional principle of this utility model can be explained through the following operation methods: Place bracket 1 on both sides of the road and press bracket 1 to make bracket 1 drive plug post 9 to extend into the ground; The width of the road is measured using a ruler, and the sleeve 6 is raised so that it moves between the two supports 1. The slider 5 is extended into the support 1, and the positioning strip 4 on the support 1 can guide the slider 5. Remove the displacement rod 7 and use a fixing bolt to connect the connecting lug to the displacement rod 7 and the connecting lug to the slider 5; Press the plate 18 so that the plate 18 drives the positioning rod 17 through the displacement rod 7 and extends into the mounting base 15. The clamping plate 19 clamps the positioning rod 17 from both sides. The plate 18 drives the mounting base 15 to extend into the extension column 20. The flatness gauge 2 is installed on the sleeve 6 by bolts. The ultrasonic testing head 3 is installed on the mounting rod 8 by bolts. When the road to be inspected is long, the second set of brackets 1 is installed so that the two sets of brackets 1 correspond to each other. The limiting rod 12 on the second set of brackets 1 extends into the limiting groove 11 in the first set of brackets 1, so that the two sets of brackets 1 are spliced ​​together. The placement degree of the brackets 1 is detected by the level 10. Pressure is applied to the sleeve 6 by the handrail, causing the sleeve 6 to move the displacement rod 7, the mounting rod 8, and the slider 5. When the slider 5 slides in the bracket 1, it adjusts the position of the ultrasonic testing head 3 and the flatness tester 2. The ultrasonic testing head 3 can detect the thickness of the asphalt pavement, and the flatness tester 2 can detect the flatness of the asphalt pavement. The impact of salt on the pavement structure can be obtained based on the test results.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
