One end of the upper gauge body is hinged to one end of the lower gauge body, and the lower surface of the upper gauge body is in contact with the upper surface of the lower gauge body, thus forming a measuring surface on the lower surface of the lower gauge body. The lower end of the adjusting screw passes through the upper gauge body and is rotatably connected to the lower gauge body. The upper gauge body and the adjusting screw are connected by a thread, and the angle between the upper and lower gauge bodies is changed by rotating the adjusting screw.

Compared to existing leveling gauges, it avoids the need for reading and then judging, saving significant time after dozens or hundreds of measurements. The measurement is simpler and more intuitive, thus improving construction efficiency.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of measuring tools, in particular to a slope ruler and a slope measuring method thereof. BACKGROUND

[0002] In order to avoid water accumulation in rainy days, a small slope needs to be set on the road pavement and square pavement, and thus the construction personnel need to measure the inclination of the pavement at any time by using a leveling ruler during the construction process. The existing method of using the leveling ruler is to place the leveling ruler on the ground to be measured, read the scale or the value displayed by the electronic display of the bubble on the leveling ruler, and finally determine whether the actual inclination is consistent with the designed inclination.

[0003] The conventional leveling ruler is used in the same way as the above measuring method, but its use is not particularly convenient, because it needs to read the actual inclination first and then determine, that is, it cannot directly determine whether the actual inclination of the ground is consistent with the designed inclination. In the entire construction process, frequent measurement is required, and because the measurement is not intuitive, the construction quality cannot be guaranteed, causing local slope disorder, causing water accumulation in rainy days, affecting the use of the site, and using the conventional leveling ruler is not conducive to improving the construction efficiency.

[0004] In addition, after the ground construction is completed, the slope detection is also performed by using the conventional leveling ruler described above, and in order to improve the detection efficiency, a leveling ruler with a length of at least 2 meters is generally selected in the detection stage. Because the detection is manually measured by hand, if the entire road surface is detected one by one, the workload is large, and thus only sampling measurement can be performed. That is, a plurality of regions are selected for measurement, and the measurement result represents the slope of the entire road surface. In fact, sampling measurement cannot accurately reflect the slope condition of the entire road surface, especially in local areas, and the problem of slope disorder and water accumulation in rainy days is prone to occur.

[0014] The application also provides a slope measurement method, which applies the above-mentioned slope ruler, includes a mobile terminal and a server, and the steps are as follows:

[0030] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as the usual meaning understood by the skilled person in the field to which the present application belongs.

[0031] Embodiment one:

[0032] As shown in Figure 1 , Figure 2 , embodiment one provides a slope ruler; comprising an upper ruler body 1, a lower ruler body 2, a bubble level 3 and an adjusting screw 4. The upper ruler body 1 and the lower ruler body 2 are the same structure, both are aluminum profile of cuboid, and the volumes are also the same, which is convenient for complete overlap. One end of the upper ruler body 1 is hinged with one end of the lower ruler body 2, and the lower surface of the upper ruler body 1 is attached with the upper surface of the lower ruler body 2, so that the lower surface of the lower ruler body 2 forms a measuring surface. The bubble level 3 is fixed on the upper surface of the upper ruler body 1, which is convenient for viewing the bubble position.

[0033] The specific connection mode of the adjusting screw 4 is as follows:

The ball 5 can rotate in the sink groove 6, balancing the displacement difference of the adjusting screw 4 after the upper ruler body 1 and the lower ruler body 2 are unfolded.

[0035] The upper ruler body 1 is threadedly connected with the adjusting screw 4. Specifically, the upper ruler body 1 is provided with a through hole 7 for the adjusting screw 4 to pass through, and a nut 8 matched with the adjusting screw 4 is arranged in the through hole 7.

The friction between the nut 8 and the clamping groove 9 is greater than the friction between the nut 8 and the adjusting screw 4. When the adjusting screw 4 is rotated, the nut 8 does not rotate, and the adjusting screw 4 and the nut 8 rotate relatively, so that the included angle between the upper ruler body 1 and the lower ruler body 2 can be quickly adjusted.
