[0002] Surveying and mapping equipment typically includes a marking device. This device is a fundamental tool or device used to mark, locate, and measure key points in surveying and mapping work. Its function is to provide benchmarks or control points for subsequent measurement, monitoring, and data analysis.

[0003] Referring to Chinese patent publication number: CN115014308B, a device for measuring and marking measuring points for marine engineering projects relates to the field of marking measuring points, and includes a fixed shell, which is configured as a rectangular shell structure, and an installation space is opened inside the fixed shell; a support seat is slidably arranged inside the installation space of the fixed shell; a collection shell is fixedly arranged on the top of the support seat; with the cooperation of the collection shell and the support seat, when the device encounters weather such as heavy rain, the support seat is retracted into the interior of the fixed shell, and the other components of the device are protected in turn, thereby extending the service life of the device and enabling the device to automatically provide protection in strong winds and heavy rain.

[0004] During geological disaster prevention and exploration, workers are required to set up portable landmarks. Due to the settlement of soft ground or the action of wind, the landmarks will be displaced. During the installation process of the landmarks, the metal nails at the bottom of the landmarks are usually inserted directly into the ground, which makes it difficult to ensure that the landmarks are installed vertically. If the insertion rod is tilted, it will cause the center point of the image measurement to deviate from the actual ground point. Summary of the Invention

[0014] Beneficial Effects: This invention provides a geological disaster prevention, exploration, and mapping device and method. Compared with existing technologies, it has the following advantages: 1. The entire device has a simple structure. The flat plate and circular plate are parallel and fixed to the exploration ground via an adjustment screw. The cylinder and the adjustment screw's threads adjust the height of one corner of the flat plate, making the flat plate and circular plate parallel to the ground. The spiral lifting member is perpendicular to the ground and completes the drilling.

[0015] 2. In order to prevent soil from contacting the first threaded hole during drilling and to ensure the depth of the drilling, the height of the first rod body and the first threaded rod cannot be less than the depth of the drilling. Therefore, the circular plate needs to have a certain height from the ground.

The side piece is a thin piece, and the outside of the side piece is a pointed tip. The distance from the blade head to the axis of the benchmark gradually decreases in the vertical direction. The bottom end of the blade head is the blade tip. The blade head facilitates the side piece to break the soil surface. Finally, the benchmark and the blade head move to the bottom of the borehole and contact the ground through the side piece. It is difficult for the benchmark to rotate under wind or external environment, reducing the possibility of the benchmark offset. BRIEF DESCRIPTION OF THE DRAWINGS

The spiral lifting member is threadedly connected to the circular plate. A ring plate 46 is provided just below the circular plate. A plurality of connecting plates 48 are connected to the side surface of the ring plate 46. The plurality of connecting plates 48 are equidistantly distributed in the circumferential direction of the ring plate 46. One end of the connecting plate 48 is connected to the inner wall of the flat plate 61. The inner wall of the ring plate 46 is provided with a plurality of second corner holes 47. The upper surface of the circular plate is parallel to the upper surface of the flat plate 61.

[0041] The spiral lifting component includes: a first rod body 21, the bottom of the first rod body 21 is connected to a first drill bit 22, the top of the first rod body 21 is connected to a first threaded rod 23, the first threaded rod 23 is connected to a handle 24 through a vertical rod, and the adjusting screw includes: a second rod body 71, the top of the second rod body 71 is connected to a second threaded rod 72, and the bottom of the second rod body 71 is connected to a second drill bit 73.

[0042] The corner groove 62 is a triangular groove, which divides a corner of the flat plate 61 into an upper plate and a lower plate. A first channel 63 is opened through the top of the upper plate, and the bottom of the first channel 63 is connected to the corner groove 62.

[0044] A method is applied to a geological disaster prevention and exploration mapping device, characterized in that: an adjusting screw is inserted into the ground, the adjusting screw is fixed to the exploration ground, a flat plate 61 is placed on the exploration ground, the first semicircular plate 31 is pushed, the spring 37 is compressed, the slider 35 moves from the first position to the second position, the first semicircular plate 31 is separated from the second semicircular plate 41, the bottom end of the spiral lifting member passes through the ring plate 46 and approaches the exploration ground, the spiral lifting member is placed between the first circular plate and the second circular plate, the first semicircular plate 31 is abutted against the second semicircular plate 41 under the thrust of the spring 37 to form a circular plate, the spiral lifting member is rotated so that the spiral lifting member is threadedly connected to the first threaded hole, the level 44 is observed and the offset direction of the flat plate 61 is determined by the position of the bubble, the cylinder 74 is threadedly connected to the adjusting screw, the cylinder 74 is rotated, and the cylinder 74 moves slowly in the vertical direction through the cylinder 74 and the upper pressure plate 76. The lower pressure plate 77 drives the flat plate 61 so that the flat plate 61 is parallel to the ground. The circular plate is parallel to the flat plate 61, then the circular plate is parallel to the ground, and the plane of the circular plate is perpendicular to the axis of the spiral lifting member. At this time, the spiral lifting member is also perpendicular to the ground. The spiral lifting member is rotated, and the tip of the spiral lifting member drills into the ground and reaches a preset depth. The first threaded rod 23 of the spiral lifting member is located below the first thread groove 43. The spiral lifting member is slidably connected to the first thread groove 43, pushing the first semicircular plate 31. The first semicircular plate 31 is separated from the second semicircular plate 41. The spiral lifting member is removed, and the bottom end of the benchmark 11 passes through the ring plate 46. The middle part of the benchmark 11 is slidably connected to the first thread groove 43. The benchmark 11 is inserted into the hole opened in the ground, reducing the adjustment time of the auxiliary benchmark 11 to be parallel to the ground, improving the accuracy of the vertical insertion of the benchmark 11 into the survey point, and facilitating the replacement of the benchmark 11 and the spiral lifting member.

[0045] During use, a relatively flat location is selected as the survey point. Each corner of the flat plate 61 is equipped with an adjustment screw. The second drill bit 73 of the adjustment screw is inserted into the ground to bring the flat plate 61 into contact with the surveyed surface. The circular plate is composed of a first semicircular plate 31 and a second semicircular plate 41. A first threaded groove 43 is defined on the inner wall of the circular plate. When the first semicircular plate 31 and the second semicircular plate 41 are in contact, the first threaded groove 43 is intact. The two slide grooves 38 extend and intersect at a corner of the flat plate 61, pulling the first semicircular plate 31 and moving it toward the corner. The spring 37 is compressed, and the first semicircular plate 31 moves along the direction of the slide groove 38 with the two first wing plates 32, the support plate 34, and the slider 35. The slider 35 moves from the first position to the second position, and the first semicircular plate 31 is separated from the second semicircular plate 41. The first rod body 21 is placed between the first semicircular plate 31 and the second semicircular plate 41, so that the bottom end of the first drill bit 22 passes through the ring plate 46 and is close to the ground. The first semicircular plate 31 is no longer pulled, and the spring 37 is restored. The spring 37 pulls the slider 35, the first wing plate 32, and the first semicircular plate 31 back to the initial position, and the slider 35 slides from the second position When the first semicircular plate 31 and the second semicircular plate 41 are moved to the first position, the bottom end of the insertion rod 39 passes through the first hole 33, the second hole 36, the third hole 51 and is plugged into the fourth hole 52 in sequence, so that the first semicircular plate 31, the support plate 34 and the slider 35 are fixed as a whole with the flat plate 61 through the insertion rod 39, which can prevent the first semicircular plate 31 and the second semicircular plate 41 from separating or offsetting in subsequent operations. The complete first threaded groove 43 is slidably connected to the first rod body 21, and the handle 24 is pressed down. The first threaded rod 23 and the first rod body 21 move vertically downward. When the first threaded rod 23 contacts the first threaded groove 43, the handle 24 is slightly turned, and the first threaded rod 23 is threadedly connected to the first threaded groove 43.

[0046] Observe the level 44 on the upper surface of the circular plate and determine whether the circular plate is level with the ground by the position of the bubble. If the bubble in the level 44 is not at the center of the instrument panel, it means that the circular plate is not parallel to the ground and the inclination angle of the circular plate needs to be adjusted. However, in order to prevent soil from contacting the first threaded hole during drilling and to ensure the depth of the drilled hole, the height of the first rod body 21 and the first threaded rod 23 cannot be less than the depth of the drilled hole. Therefore, the circular plate needs to be at a certain height from the ground. Because there is a height difference between the circular plate and the ground, it is difficult to directly adjust the circular plate and make it level with the ground. The circular plate is fixedly connected to the flat plate 61, and the circular plate and the flat plate 61 are arranged parallel to each other. The circular plate and the flat plate 61 move synchronously, and the inclination angle of the circular plate is adjusted by fine-tuning the inclination angle of the flat plate 61. The offset direction of the plate 61 is determined by the position of the bubble. If the bubble is to the left, it means that the left side of the level 44 is too high. The left side of the plate 61 needs to be lowered or the right side needs to be raised. After finding the corresponding adjustment position of the plate 61, the lever 75 is rotated. The lever 75 drives the cylinder 74 to rotate. The cylinder 74 is threadedly connected to the second threaded rod 72. The cylinder 74 drives the upper pressure plate 76 and the lower pressure plate 77 to move along the axis of the second threaded rod 72. If the cylinder 74 moves downward, the cylinder 74 drives the lower pressure plate 77 to squeeze a corner of the plate 61 and move the plate 61 downward. If the cylinder 74 moves upward, the cylinder 74 drives the upper pressure plate 76 to squeeze a corner of the plate 61 and move the plate 61 upward. For each rotation of the cylinder 74, the corner of the plate 61 rises by 0.05-0.1mm. The plate 61 moves slightly under the drive of the cylinder 74. When the bubble of the level 44 moves to the center of the instrument panel, the lever 75 is no longer rotated. The circular plate is parallel to the ground and the axis of the circular plate is perpendicular to the survey point on the ground.

[0047] Turn the handle 24, the first threaded rod 23 moves downward along the axis of the first threaded hole, the first drill bit 22 drills into the soil and drills to a predetermined depth to form a borehole. The depth of the borehole is usually greater than 50 cm. The bottom end of the borehole passes through the soft stratum and is located in the solid bottom layer. Remove the insertion rod 39, pull the first semicircular plate 31, the spring 37 is compressed, the gap between the first semicircular plate 31 and the second semicircular plate 41 increases, and the spiral lifting member is removed.

[0048] Place the marker rod 11 between the first semicircular plate 31 and the second semicircular plate 41, and pass the bottom end of the marker rod 11 through the ring plate 46. The first semicircular plate 31 and the second semicircular plate 41 are combined into a circular plate, and the flat plate 61 is fixed to the circular plate by the insertion rod 39; or first fix the flat plate 61 to the circular plate by the insertion rod 39, and then pass the bottom end of the marker rod 11 through the first threaded hole and the ring plate 46 in sequence, and the side piece 12 on the marker rod 11 is slidably connected with the first corner hole 45 and the second corner hole 47.

[0049] The marker 11 can only move in the vertical direction under the limiting effect of the first threaded hole and the inner diameter of the ring plate 46, preventing the marker 11 from deflecting during the downward movement. The distance between the side piece 12 and the axis of the marker 11 is slightly larger than the diameter of the drill hole. The side piece 12 is a thin piece with a pointed tip on the outside. The distance between the blade head 13 and the axis of the marker 11 gradually decreases in the vertical direction. The bottom end of the blade head 13 is a blade tip, which facilitates the side piece 12 to break the soil surface. Finally, the marker 11 and the blade head 13 move to the bottom of the drill hole and contact the ground through the side piece 12. The marker 11 is difficult to rotate under wind or external conditions, reducing the possibility of the marker 11 deflecting.

[0050] The entire device has a simple structure. The flat plate 61 is parallel to the circular plate and is fixed to the exploration ground through an adjusting screw. Under the action of the cylinder 74 and the thread of the adjusting screw, the height of one corner of the flat plate 61 is changed so that the flat plate 61 and the circular plate are parallel to the ground. The spiral lifting member is perpendicular to the ground and completes the drilling. The elastic action is used to control the separation and combination of the circular plate, which facilitates the replacement of the spiral lifting member and the benchmark 11, speeds up the placement of the benchmark 11, and ensures that the benchmark 11 is perpendicular to the survey point.
