[0021] according to Figure 1-3As shown, a ditch excavation detection device includes a level 3, a level base 4, a level 1, and a measuring mechanism 2. The measuring mechanism 2 includes a ruler 21, a slant ruler 22, and a square 23. The level 1 is detachably mounted on the ruler 21 and is arranged parallel to the ruler 21. One end of the slant ruler 22 is hinged to the pivot pin of the ruler 21. One end of the square 23 is fixedly connected to the slant ruler 22, and its free end extends upward and is slidably connected to the ruler 21. The level base 4 is slidably connected to the level 3, and a first locking bolt 5 for abutting against the level 3 is threaded onto the level base 4. The free end of the ruler 21 is connected to the level base 4.

[0022] according to Figure 1-3 As shown, the free end of the scale 21 is hinged to the axis of the scale base 4. The scale base 4 is provided with an arc-shaped guide rail 41. The center of the arc of the arc-shaped guide rail 41 is concentric with the hinge point of the scale 21. An arc-shaped through groove is provided on the arc-shaped guide rail 41. A second locking bolt 6 is inserted into the arc-shaped through groove. The second locking bolt 6 is threadedly connected to the free end of the scale 21.

[0023] according to Figure 1-3 As shown, the scale 21 and the slant ruler 22 are hinged together by a pivot pin on the hollow tube 8. The inner wall of the hollow tube 8 is threaded, and the third locking bolt 7 is threadedly connected to the hollow tube 8. The angle ruler 23 is equipped with a pin 9 for marking the inclination angle of the slant ruler 22. The pin 9 is slidably connected to the angle ruler 23 or magnetically connected.

[0024] according to Figure 1-3 As shown, because the slant ruler 22 and the scale 21 are hinged, the slant ruler 22 can be tilted to the corresponding angle as required, and the tilt angle of the slant ruler 22 can be calibrated by the angle ruler 23. The levelness of the scale 21 can be calibrated by the level instrument 1, making it more flexible and convenient to use.

[0025] according to Figure 1-3 As shown, the method of using the ditch excavation detection device is as follows: Insert the lower end of the tag into the slope of the ditch, then use the level 1 to adjust the scale 21 until it is horizontal. After the scale 21 is horizontal, fix the scale 21 with the third locking bolt 7. Move the sliding base 4 to a suitable height, and use the first locking bolt 5 to fix the base 4 and the scale rod 3. At this time, rotate the inclined ruler 22 according to the mark on the square 23 to keep the inclined ruler 22 at a specific tilt angle. Fix the inclined ruler 22 and the scale 21 with the third locking bolt 7. Finally, by observing whether the inclined ruler 22 is in contact with the slope of the ditch, it can be determined whether the slope excavation of the ditch meets the design requirements. Alternatively, the inclined ruler 22 can be directly placed in contact with the slope of the ditch, and the scale on the square 23 can be observed to determine the tilt angle of the ditch slope. The reading position of the pointer on the square 23 is used as a mark.
