Scientific testing methods are needed to accurately evaluate the bearing capacity and strength of the pavement to ensure the safety and durability of the highway. The differences in geographical environment, climatic conditions, traffic flow and other factors in different regions have also prompted targeted research and improvements to highway pavement strength testing technology to better adapt to various complex actual situations.

[0003] Due to route planning and design, highway pavements have many curved slopes. During testing, the various slopes on the road have different characteristics, and the specific requirements for equipment also vary. In addition, the strengths tested for different road surface flatness conditions are also different. If, during the entire test process, the equipment's foot support is affected by the unevenness of the road surface, such as unstable support or tilt, then the final pressure strength data obtained from the test will inevitably be affected, resulting in deviations or inaccuracies. In this case, the data obtained may not truly and accurately reflect the actual strength of the road surface, which will mislead the subsequent assessment, analysis, and related decision-making of the road surface condition, and may even have a series of adverse effects on the construction, maintenance, and use of the highway.

The side wall of the connecting ring 102 is connected to the top of the side wall of the pressing piece 104. The part of the spiral rod passes through the inside of the balance box 301 and the spiral ring to its lower end, pulling down the two side ends of the pressing block 101 at the bottom of the pressing mechanism 1, thereby driving the pressing piece 104 at the side end to press the pump downward.

[0034] Example 3

[0035] like Figure 1 、 Figure 3 and Figure 4 As shown, the balancing mechanism 3 includes a balancing box 301, the outer bottom end of the electric push rod 4 passes through and is slidably connected to the balancing box 301, the outer wall bottom end of the support rod 2 passes through and is connected to the center of the balancing box 301, and the driving device 401 drives the electric push rod 4 to perform downward pressure control. The bottom end of the electric push rod 4 passes through the inner side of the two ends of the balancing box 301 until the part of the electric push rod 4 passes through the interior of the balancing box 301 to its lower end;

[0036] like Figure 1-Figure 2As shown, the data display mechanism 6 includes an adjusting shaft 601, a data transmission sensor 602 and a data dial 3.

The bottom end of the data transmission sensor 602 is fixedly connected to the top side of the pressing mechanism 1. The pressing piece 104 presses the box body 103 downward, thereby pressing the top of the side wall of the box body 103. The gas pressure data can be transmitted to the data dial 603 through the inside of the data transmission sensor 602 and read.

[0037] How it works

[0038] like Figures 1-6 As shown, first, the bottom of the retaining mechanism 7 is placed on the road surface, while at the same time, the bottom of the supporting platform 5 is tightly attached to the top side of the road surface. At this time, the pressure generated by the bottom of the supporting platform 5 can be accurately measured by the support rod 2 to generate a pressure signal. In this way, the compressive strength of the road can be measured in a targeted manner, and this pressure signal will be transmitted to the data display mechanism 6 at the top. Then, according to the actual height conditions of the surrounding areas, the positions of the retaining mechanism 7 are carefully adjusted. By adjusting the L-shaped frame 701 and the support frame 702 to slide up and down, the inner side of the L-shaped frame 701 can slide smoothly up and down along the outer side of the support frame 702, thereby effectively balancing the supporting force of the bottom of the entire balancing mechanism 3.

[0039] The electric push rods 4 on both sides of the balancing mechanism 3 perform a downward pressing operation. During this process, the bottom end of the electric push rod 4 will pass through the inner side of the spiral ring, and the electric push rod 4 will pass through the inside of the balancing box 301 to its lower end, and then press the top side of the pressing block 101 downward, so that the surrounding of the pressing block 101 will drive the side end pressure piece 104 to press the side wall of the box body 103 downward. It should be noted that when the pressure piece 104 is pressed downward, it will be restricted by the connecting ring 102, so the pressure pieces 104 around the box body 103 can all move downward at the same time, so that they can press the top of the side wall of the box body 103 to achieve targeted measurement of road strength. In addition, the position of the adjusting shaft 601 can also clear the data on the data dial 603, and the gas pressure data can be combined with the above-mentioned measured pressure signal through the inside of the data transmission sensor 602. After a series of data processing After the operation, it is finally transmitted to the data dial 603 for relevant personnel to view and analyze. When the pressing mechanism 1 loses the downward pressing force, the reset spring 801 can drive the support member 802 to pull upward forcefully, and this upward pulling force will be further transmitted to the top side of the pressing block 101, thereby acting on the pressing block 101. Under the influence of this pulling force, the pressing block 101 will stretch to both sides and stretch the box 103 around it. Since the bottom end of the data display mechanism 6 serves as the key support inside the pressing mechanism, in this case, the pressing block 101 can effectively lift the side walls of the surrounding box 103 upward. Since the pressing block 101 itself is non-elastic, it can ensure that the side walls of the box 103 can gradually restore their original shape, so that it maintains good shape and structural integrity, thereby ensuring the normal operation of the entire device and the stable use of its functions.
