[0002] There are various ways for highway base flatness detection, and the commonly used and inexpensive way is to use a three-meter ruler to detect. When using this way to detect, the road surface evaluation standard is: detecting 2 places every 200m, and detecting 5 feet every place. As for the detection position: except for special needs, the wheel track on one side of the lane (0.8m-1m away from the lane line) should be used as the continuous test position. Before cleaning, the road surface is first cleaned. After placing the ruler on the road surface, the ruler is inserted into the gap between the ruler body and the ground, and the vernier is pushed to read the degree and record the data. The data of multiple measurements are used to determine the flatness of the highway base.

[0021] The following will be described in detail in combination with the accompanying drawings. Figure 1 - Figure 5 The present application will be further described in detail.

[0022] Embodiment One:

[0023] A highway base surface flatness detection device, refer to Figure 1 Figure 3 The measuring scale includes a first measuring scale 1 and a second measuring scale 2 which are hingedly connected to each other, and a level tube 4 is installed on the measuring scale. The first measuring scale 1 and the second measuring scale 2 are fixed by a buckle structure 3. The buckle structure 3 can be any buckle structure which can keep the first measuring scale 1 and the second measuring scale 2 in a relatively flat position after being unfolded. For example, a pin shaft is arranged on the first measuring scale 1, and a knob is used to fix a buckle piece on the second measuring scale 2. A groove is arranged on the buckle piece to buckle the pin shaft. After the buckle piece is buckled with the pin shaft, the knob is tightened to limit the position of the first measuring scale 1 and the second measuring scale 2. An adjusting part is arranged on the first measuring scale 1 and the second measuring scale 2. A measuring assembly is coupled to the adjusting part. The adjusting part is used to adjust the horizontal position of the measuring assembly on the measuring scale. The measuring assembly includes an iron sheet 621 which is slidably connected to the adjusting part. A measuring rod 6 is slidably arranged on the iron sheet 621. The measuring rod 6 is perpendicular to the horizontal plane. A scale 611 is marked on the top end of the measuring rod 6. The plane where the upper end surface of the iron sheet 621 is located corresponds to the scale 611, which is the clearance between the measuring scale and the ground.

[0024] The adjusting part is a sleeve 51 which is welded on the first measuring scale 1 and the second measuring scale 2. The side view of the sleeve 51 is in a C-shaped structure. A ball 622 is rotatably arranged on one side of the iron sheet 621. The ball 622 is slidably arranged in the inner side of the sleeve 51. The ball 622 is in contact with the bottom end of the sleeve 51, and the top end of the ball 622 is not in contact with the sleeve 51. The ball 622 improves the smoothness of the iron sheet 621 in the sleeve 51 and reduces the friction. The C-shaped opening of the sleeve 51 is in gap cooperation or contact with the upper and lower end surfaces of the iron sheet 621. The iron sheet 621 is always in a horizontal state, which ensures the accuracy of the measurement and reduces the error. A vertical pipe 63 is welded on the iron sheet 621. The measuring rod 6 is slidably arranged in the vertical pipe 63 and coaxially arranged with the vertical pipe 63. A limiting piece 612 is welded on the top end of the measuring rod 6. The diameter of the limiting piece 612 is larger than the inner diameter of the vertical pipe 63, which ensures that the measuring rod 6 will not fall out of the vertical pipe 63. In order to further improve the stability of the measuring rod 6 in the vertical pipe 63, a limiting piece 612 can be arranged on the bottom end of the measuring rod 6. However, the measuring rod 6 without the limiting piece 612 can be replaced to adapt to different highway base surface flatness. This can avoid the situation that the measurement cannot be performed due to the excessive clearance between the measuring scale and the ground.

[0027] The adjusting part is a magnetic strip 52 which is glued on each of the first measuring scale 1 and the second measuring scale 2, and the magnetic strip 52 has a flat structure. The iron sheet 621 and the magnetic strip 52 are adsorptively matched. The convenient detachability between the magnetic strip 52 and the iron sheet 621 is used to conveniently switch the position of the measuring rod 6 on the magnetic strip 52, so as to conveniently measure different positions.
