When the roadbed is detected, a pre-buried pit is first dug on the roadbed, the base plate is placed in the pre-buried pit, the base plate is adjusted to be in a horizontal state, the staff holds the measuring tube and buries the base plate. When the base plate is subjected to external pressure, the base plate will produce vertical displacement.

The slide plate 13 is parallel to the displacement plate 3, and both ends of the slide plate 13 extend into the guide rails 12 on both sides respectively, and the slide plate 13 and the guide rails 12 are slidably connected.

[0035] After the support plate 1 is adjusted, the displacement plate 3 is slid in the direction away from the support plate 1. Under the guidance of the guide rail 12, the displacement plate 3 drives the slide plate 13 to move. At the same time, the displacement plate 3 drives the second screw 37 to move, and the second screw 37 drives the roller 371 to move. After the displacement plate 3 reaches the set position, the second screw 37 is rotated, and the second screw 37 drives the roller 371 to move, so that the roller 371 contacts the ground, so that the roller 371 and the second screw 37 support the displacement plate 3.

[0036] refer to Figure 1 The upper ends of the first screw rod 21 and the second screw rod 37 are fixedly connected with a hand wheel 9. When the hand wheel 9 is turned, the hand wheel 9 drives the first screw rod 21 or the second screw rod 37 to rotate. The setting of the hand wheel 9 provides convenience for rotating the first screw rod 21 and the second screw rod 37.

[0037] refer to Figure 1 and Figure 2 A fixing rod 14 is fixedly connected to the middle of the upper surface of the skateboard 13, and the fixing rod 14 is perpendicular to the skateboard 13. A fixing block 6 is arranged above one end of the guide rail 12, and the fixing block 6 is parallel to the support plate 1. The length direction of the fixing block 6 is perpendicular to the guide rail 12, and the relative connection of the lower surface of the fixing block 6 is respectively fixedly connected to the upper surfaces of the guide rails 12 on both sides. A fixing groove 61 is provided on the side of the fixing block 6 facing the fixing rod 14, and the fixing groove 61 runs through the upper and lower sides of the fixing block 6, and the fixing rod 14 is plugged and adapted to the fixing groove 61, and a second fixing component 5 for fixing the fixing rod 14 is arranged at the fixing block 6.

[0038] The fixed block 6 is provided with a first movable groove 62 along its own length direction on one side wall of the fixed groove 61. The second fixed component 5 includes a baffle 51 and a first spring 52. One end of the baffle 51 is in the first movable groove 62. The baffle 51 and the fixed block 6 are slidably connected.

[0039] In the process of the displacement plate 3 moving toward the support plate 1, the displacement plate 3 drives the slide plate 13 to move, and the slide plate 13 drives the fixing rod 14 to move. In the process of the fixing rod 14 moving toward the fixing groove 61, the fixing rod 14 first contacts the inclined surface of the baffle plate 51 and pushes the baffle plate 51 to move toward the first moving groove 62, and the first spring 52 is compressed. When the baffle plate 51 and the fixing rod 14 are separated, the first spring 52 releases its elastic force and pushes the baffle plate 51 to move toward the fixing groove 61. The end of the baffle plate 51 away from the first spring 52 extends to the fixing groove 6 1, the baffle plate 51 blocks the fixing rod 14, making it difficult for the fixing plate 7 to move out of the fixing groove 61, thereby making it difficult for the sliding plate 13 to move, and the displacement plate 3 to move in the direction away from the support plate 1. When the displacement plate 3 needs to move in the direction away from the support plate 1, the pull plate 64 is pulled in the direction away from the fixing block 6, the pull plate 64 drives the pull rod 63 to move, and the pull rod 63 drives the baffle plate 51 to move, so that the baffle plate 51 moves into the first moving groove 62, and the blocking of the fixing rod 14 is released, so that the displacement plate 3 can move in the direction away from the support plate 1.

The length direction of the measuring rod 31 is parallel to the length direction of the second screw 37. The measuring rod 31 passes through the displacement plate 3 and is slidably connected to the displacement plate 3. The bottom end of the measuring rod 31 is fixedly connected to a bottom plate 32. The bottom plate 32 and the measuring rod 31 are perpendicular. A first fixing component 4 for fixing the measuring rod 31 is provided on the displacement plate 3.

[0041] A first sliding groove 33 is provided on the upper surface of the displacement plate 3, and two first sliding blocks 34 are slidably connected in the first sliding groove 33 of the displacement plate 3.

First slots 311 are provided on opposite sides of the measuring rod 31. The first fixing component 4 includes a moving rod 41 and a first plug rod 42. There are two moving rods 41 and two first plug rods 42, and they correspond to each other. The length direction of the moving rod 41 is parallel to the length direction of the guide rail 12. The moving rod 41 and the upper surface of the first sliding block 34 are fixedly connected and correspond to each other. The two moving rods 41 are respectively located on opposite sides of the measuring rod 31. One end of the moving rod 41 close to the measuring rod 31 is fixedly connected to the first plug rod 42. The first plug rod 42 is perpendicular to the moving rod 41, and the first plug rod 42 is plugged and adapted to the first slot 311.

[0042] The displacement plate 3 is moved in a direction away from the support plate 1, and the displacement plate 3 drives the measuring rod 31 to move, and the measuring rod 31 drives the bottom plate 32 to move.

The measuring rod 31 and the bottom plate 32 are affected by their own gravity, and the measuring rod 31 and the bottom plate 32 move downward, and the bottom plate 32 falls into the pre-buried pit to bury the bottom plate 32. At the same time, during the burying process, the measuring rod 31 is moved by the displacement plate 3. The restriction of the rod 31 makes it difficult for the measuring rod 31 to tilt, so that the bottom plate 32 is always in a horizontal state. After the detection is completed, the bottom plate 32 is removed from the embedded pit and pushed upward. The bottom plate 32 drives the measuring rod 31 to move. When the first slot 311 and the first insertion rod 42 are aligned, the two moving rods 41 are moved in relative directions. The moving rod 41 drives the first insertion rod 42 to move. One end of the first insertion rod 42 is inserted into the first slot 311 to complete the fixation of the measuring rod 31, so that the measuring rod 31 is not easy to move downward, which provides convenience for storing the measuring rod 31 and the bottom plate 32.

[0044] When the displacement plate 3 moves to the set position, the two moving rods 41 are moved in opposite directions to release the fixation of the measuring rod 31. At the same time, the moving rod 41 drives the support rod 35 to move, and the support rod 35 drives the second insertion rod 36 to move. The end of the second insertion rod 36 is inserted into the second slot 71, so that the second insertion rod 36 and the fixed plate 7 are relatively fixed, and then the support rod 35, the moving rod 41 and the displacement plate 3 are fixed. In the process of burying the bottom plate 32, the displacement plate 3 is not easy to move.

[0045] refer to Figure 1 , Figure 3 and Figure 5 A drawing board 39 is fixedly connected to the upper surface of the displacement plate 3, and the drawing board 39 is perpendicular to the displacement plate 3.

A second spring 83 is fixedly provided between the side of the push plate 82 away from the drawing pen 38 and the side wall of the placement shell 8. The telescopic direction of the second spring 83 is parallel to the length direction of the drawing pen 38.

[0046] After the base plate 32 is buried, the push plate 82 is pushed in the direction away from the buckle 81, the second spring 83 is compressed, and the marking pen 38 is snapped into the buckle 81, the push plate 82 is released, and the second spring 83 releases its elastic force, pushing the push plate 82 to move in the direction of the marking pen 38, and the push plate 82 pushes the marking pen 38 to move in the direction of the drawing board 39, and the front end of the marking pen 38 abuts against the drawing paper 391.
