The surveying instrument 2 is an existing device, and its specific surveying function can be adjusted according to the specific usage. There are three first legs 3, and the three first legs 3 are evenly distributed circumferentially. A rectangular notch is opened in the middle of the second leg 4 for accommodating the first extrusion plate 501. The central axes of the two first arc plates 5 on the same second leg 4 and the central axis of the base 1 are located on the same vertical plane, which are used to support the inner and outer sides of the three first legs 3 at the same time, ensuring that the first arc plates 5 generate friction when in contact with the soil, and strengthening The stability of the device is as follows: the vertical cross-section of the first arc plate 5 is L-shaped, a plurality of first extrusion plates 501 are evenly distributed on the inner side of the first arc plate 5, the first extrusion plate 501 is a thin plate made of a hard material, the first elastic member 6 is a coil spring, two first elastic members 6 are fixedly connected to the first arc plate 5, and are used to make the force of the first arc plate 5 more stable when rotating, the sliding rod 7 runs through the middle of the lower side of the second leg 4, and the cross-section of the sliding rod 7 is T-shaped, and is used to extrude two adjacent first arc plates 5, the second elastic member 8 is a tension spring, and the extrusion block 9 is composed of a cone and a cylindrical block, and the diameter of the cylindrical block of the extrusion block 9 is the same as that of the second leg 4.

[0053] Combination Figure 4-Figure 8As shown, the expansion assembly includes: a second arc plate 1101, which is slidably connected to the extrusion block 9, and a slope is provided at the lower part of the second arc plate 1101 away from the extrusion block 9, and a third elastic member 1102 is fixedly connected between the extrusion block 9 and the second arc plate 1101; a first limit block 1103, which is fixedly connected to the second arc plate 1101, and the first limit block 1103 slides along the extrusion block 9, and the extrusion block 9 is slidably connected to the second limit block 1104, and the first limit block 1103 Used to limit the second limiting block 1104, a fourth elastic member 1105 is fixedly connected between the extrusion block 9 and the second limiting block 1104, and the extrusion block 9 is detachably connected with a cover plate 1106; a rectangular plate 1107 is fixedly connected to the second limiting block 1104, the cover plate 1106 is slidably connected to the rectangular plate 1107, and the distance from the side of the rectangular plate 1107 close to the second leg 4 to the extrusion block 9 is greater than the height of the fitting surface between the first limiting block 1103 and the second limiting block 1104.

[0054] In the above scheme, the diameter of the circle corresponding to the outer side surface of the second arc plate 1101 is equal to the diameter of the circle corresponding to the cylindrical block of the extrusion block 9. The cylindrical block of the extrusion block 9 is provided with a cylindrical slide groove. The lower inclined surface of the second arc plate 1101 away from the extrusion block 9 is used to increase the contact area between the second arc plate 1101 and the side wall of the arc notch on the soil near the extrusion block 9, improve the friction between the second arc plate 1101 and the side wall of the arc notch on the soil near 9, and enhance the stability of the first leg 3. The third elastic member 1102 is a spring and is initially in a compressed state. The third elastic member 1102 is located in the cylindrical slide groove of the extrusion block 9. The first limit block 1103 and the second limit block 1104 are both provided with inclined surfaces with the same inclination, so that when the two move toward each other, the first limit block 1103 provides a more stable extrusion force on the second limit block 1104, the fourth elastic member 1105 is a spring, and the cover plate 1106 can be connected to the extrusion block 9 by a snap, which is convenient for the subsequent replacement and maintenance of the parts in the extrusion block 9, and the distance from the upper side surface of the rectangular plate 1107 to the upper side surface of the extrusion block 9 is greater than the height of the vertical surface of the first limit block 1103 and the second limit block 1104, which is used to ensure that the first limit block 1103 is released from the limit of the second limit block 1104.

[0055] Combination Figure 4 , Figure 8 and Fig.11 As shown, the extrusion assembly includes: a fixed ring 1201, fixedly connected to the first leg 3, the first leg 3 and the adjacent second leg 4 are slidably connected with a sliding ring 1202, and a fifth elastic member 1203 is fixedly connected between the fixed ring 1201 and the sliding ring 1202; an extrusion shell 1204, rotatably connected to the sliding ring 1202; and limiting assemblies, the number of which is consistent with the number of the first legs 3, and are respectively arranged on adjacent first legs 3, and the limiting assemblies are used to limit the sliding of the sliding ring 1202.

[0056] In the above scheme, the fifth elastic member 1203 is a spring and is initially in a compressed state. The diameter of the circle corresponding to the outer arc surface of the first arc plate 5 is equal to the diameter of the circle corresponding to the second leg 4, which is used to ensure that the sliding ring 1202 is not blocked by the first arc plate 5 when sliding along the second leg 4. The inner side surface of the sliding ring 1202 and the outer side surfaces of the first leg 3 and the second leg 4 are all smooth, which is used to reduce the friction force of the sliding ring 1202 when sliding along the first leg 3 and the second leg 4. The weight of the extrusion shell 1204 is adjusted according to the specific usage to ensure that the lower side of the extrusion shell 1204 is always parallel to the ground.

[0057] Combination Figure 4 , Figure 5 and Figure 8-Figure 10 As shown, the limiting assembly includes: a second extrusion plate 1205, which is slidably connected in the rectangular slide groove of the extrusion block 9, and the height of the rectangular slide groove of the extrusion block 9 is greater than the distance between the extrusion block 9 and the second leg 4; an n-shaped plate 1206, which is fixed in the cylindrical blind hole of the first leg 3, and the first leg 3 is slidably connected with a trapezoidal block 1207, the second extrusion plate 1205 is used to extrude the trapezoidal block 1207, the trapezoidal block 1207 is used to limit the sliding ring 1202, and a sixth elastic member 1208 is fixed between the n-shaped plate 1206 and the trapezoidal block 1207; locking assemblies, the number of which is consistent with the number of extrusion blocks 9, and are respectively arranged on adjacent extrusion blocks 9, and the locking assemblies are used to lock the position of the second extrusion plate 1205.

[0058] In the above scheme, the height of the rectangular slide groove of the extrusion block 9 is greater than the distance from the upper side of the extrusion block 9 to the lower side of the second leg 4, which is used to ensure that the second extrusion plate 1205 can slide downward without affecting the fit between the extrusion block 9 and the second leg 4. The seventh elastic member 1210 is a spring, which is used to drive the limit plate 1209 to reset. There are two n-shaped plates 1206 in the cylindrical blind hole of the first leg 3. The sixth elastic member 1208 is a tension spring, and is initially in a force-accumulating stretched state, which is used to drive the trapezoidal block 1207 to reset.

[0059] Combination Fig.10 As shown, the locking assembly includes: a limiting plate 1209 slidably connected to the second arc plate 1101 , the limiting plate 1209 is used to limit the second extrusion plate 1205 , and a seventh elastic member 1210 is fixedly connected between the limiting plate 1209 and the second arc plate 1101 .

[0060] In the above solution, the thickness of the limiting plate 1209 is equal to the thickness of the second extrusion plate 1205, so as to provide a more stable support, and the seventh elastic member 1210 is a spring.

[0061] When using the device to survey a building, the worker first bends the three first legs 3 outward until the angle is appropriate. The first leg 3 swings outward, driving the parts on it to swing outward. Then the device is pressed downward to fix the device to the soil, and ensure that the second arc plate 1101 is below the soil surface. If the fixed area is soft soil, one of the first legs 3 and its attached parts are used as an example for description: the first leg 3 moves downward, driving the second leg 4 to move downward. The second leg 4 moves downward, driving the sliding rod 7 downward through the second elastic member 8. The sliding rod 7 drives the extrusion block 9 downward. The extrusion block 9 squeezes the soft soil and moves downward, and the attached parts An arc-shaped gap is formed in the soil near the ground. As the first leg 3 moves downward, the first arc-shaped plates 5 in the inner circle corresponding to the three first legs 3 gradually contact the soil, and together with the squeezing plates 501 thereon, drive the soil downward to compact the soil, thereby improving the compactness of the soil. Subsequently, the first arc-shaped plates 5 in the outer circle corresponding to the three first legs 3 contact the ground, and together with the squeezing plates 501 thereon, drive the soil downward to compact the soil, thereby improving the supporting force by compacting the soil with the squeezing plates 501 and the support formed by the outer first arc-shaped plates 5 and the ground, thereby further improving the stability of the first leg 3 and the second leg 4 and reducing the possibility of the device tipping over.

[0062] When the device is fixed, the surveying instrument is started to start surveying.

[0063] When the device is no longer used for surveying, the staff first pulls the device out of the soil and cleans the soil attached to the first leg 3 and its accessory parts to complete the recovery of the device.

[0064] When the fixed area is compacted soil, one of the first legs 3 and its attached parts are taken as an example for description: the extrusion block 9 overcomes the elastic force of the second elastic member 8 and moves upward under the extrusion of the soil, and the upward movement of the extrusion block 9 drives the sliding rod 7 to move upward and gradually contacts the two first arc-shaped plates 5, the second elastic member 8 is stretched, and then the upper side of the sliding rod 7 squeezes the two first arc-shaped plates 5, and the two first arc-shaped plates 5 swing toward each other to twist the two adjacent first elastic members 6.

[0065] When the upper side of the extrusion block 9 moves upward relative to the second leg 4 to fit with the lower side of the second leg 4, the two first arc-shaped plates 5 swing under the extrusion of the sliding rod 7 to be parallel to the center line of the first leg 3, reducing the force required to press downward when fixing the device.

[0066] When the extrusion block 9 moves upward relative to the second leg 4, the extrusion block 9 drives its internal accessories to move upward, and the rectangular plate 1107 moves upward, and its upper side surface gradually contacts with the lower side surface of the second leg 4. Then, the rectangular plate 1107 moves downward relative to the extrusion block 9 under the extrusion of the lower side surface of the second leg 4. The rectangular plate 1107 drives the second limit block 1104 to move downward, and the second limit block 1104 squeezes the fourth elastic member 1105 to shrink it.

[0067] As the second limit block 1104 moves downward, the second limit block 1104 releases the limit on the first limit block 1103. At this time, the second arc plate 1101 moves outward under the action of the elastic force of the third elastic member 1102. At the same time, the extrusion block 9 moves downward driven by the second leg 4 to squeeze the compacted soil nearby, so that a rectangular gap is formed in the nearby soil. The extrusion block 9 drives the second arc plate 1101 to move downward. The inclined surface of the second arc plate 1101 contacts the inner side wall of the rectangular gap in the soil near the extrusion block 9 under the action of the elastic force of the third elastic member 1102, thereby enhancing the anti-tilt ability of the first leg 3.

[0068] When the extrusion block 9 moves upward relative to the second leg 4, the second extrusion plate 1205 moves downward along the rectangular slide groove of the extrusion block 9, and the second extrusion plate 1205 drives the limiting plate 1209 to move downward and compresses the seventh elastic member 1210 until the upper side surface of the extrusion block 9 is in contact with the lower side surface of the second leg 4, and the second extrusion plate 1205 stops moving downward along the rectangular slide groove of the extrusion block 9.

[0069] When the second arc plate 1101 moves outward, the second arc plate 1101 drives the limiting plate 1209 to move outward, and releases the limiting plate 1209 from squeezing the second squeezing plate 1205. The second squeezing plate 1205 moves downward under the action of its own gravity and the squeezing of the trapezoidal block 1207. The second squeezing plate 1205 moves downward to release the squeezing of the trapezoidal block 1207. The trapezoidal block 1207 slides toward the cylindrical blind hole of the first leg 3 under the action of the elastic force of the two sixth elastic members 1208. When the trapezoidal block 1207 slides toward the cylindrical blind hole of the first leg 3 until the squeezing of the sliding ring 1207 is released, the sliding ring 1207 is released. After the limit of 202, the sliding ring 1202 slides downward under the action of the elastic force of the fifth elastic member 1203, and the sliding ring 1202 drives the extrusion shell 1204 to slide downward. The extrusion shell 1204 is always in a position with its center line perpendicular to the ground under the action of its own gravity. The extrusion shell 1204 slides downward and gradually contacts the ground, thereby strengthening the supporting effect of the device. Subsequently, the extrusion shell 1204 squeezes the arc-shaped notch portion on the soil near the extrusion block 9, compacts the soil near the arc-shaped notch, and further strengthens the friction between the second arc plate 1101 and the inner wall of the arc-shaped notch.

[0070] When the device is no longer used for surveying and mapping, the staff pulls the device out of the soil and cleans the soil contained in the first leg 3 and its attached parts. During the pulling-out process, the sliding rod 7 moves downward relative to the first leg 3 driven by the elastic force of the second elastic member 8. The sliding rod 7 moves downward to release the squeezing of the two first arc plates 5. The two first arc plates 5 are reset respectively driven by the elastic force of the two adjacent first elastic members 6. The sliding rod 7 drives the squeezing block 9 to move downward. The squeezing block 9 moves downward and drives the attached parts thereon to move downward. The second limit block 1104 moves upward relative to the squeezing block 9 driven by the elastic force of the fourth elastic member 1105 to reset. After the second limit block 1104 drives the rectangular plate 1107 to reset, the staff first pulls the sliding ring 1202 upward until the trapezoidal block 1207 is aligned with the sliding ring 1202. At the same time, the staff pulls the second squeezing ring 1202 upward to release the squeezing of the two first arc plates 5. Press plate 1205 until the lower side of the second extrusion plate 1205 is higher than the upper side of the limit plate 1209, stop pulling the second extrusion plate 1205, the second extrusion plate 1205 moves upward to extrude the trapezoidal block 1207, the trapezoidal block 1207 is squeezed and slides outward, locks the sliding ring 1202 and stretches the two sixth elastic members 1208, and finally the staff presses the second arc plate 1101 to make the second arc plate 1101 and its attached parts slide along the center direction of the extrusion block 9, and compress the third elastic member 1102, the second arc plate 1101 drives the first limit block 1103 to slide, so that the first limit block 1103 and the second limit block 1104 are re-limited and locked, stop pressing the second arc plate 1101, and release the second extrusion plate 1205 at the same time, the second extrusion plate 1205 moves downward and limits itself with the limit plate 1209 again, completing the resetting of the device.

[0071] In the existing construction project surveying and mapping process, the surveying and mapping position will be moved many times due to the influence of terrain and obstacles. However, the existing surveying and mapping equipment does not have the function of measuring point marking. Therefore, workers are required to manually use marking dust to mark, which is very time-consuming and reduces the work efficiency of surveying and mapping. In addition, the soft soil contains a certain amount of moisture, which may cause the marking dust to melt, resulting in the disappearance of the marks or the unclear marks after a period of time.

[0072] Embodiment 2: Based on Embodiment 1, Figure 10-12As shown, it also includes: punctuation components, the number of which is consistent with the number of the first legs 3, and are respectively arranged on adjacent extruded shells 1204, the punctuation components are used to mark the position of the soil compaction, and the punctuation components include: a baffle plate 1301, which is detachably connected to the extruded shell 1204, the extruded shell 1204 is slidably connected to a sliding column 1302, the sliding column 1302 is fixedly connected to a circular shell 1303, in the vertical direction, the minimum distance from the lower side of the sliding column 1302 to the circular shell 1303 is greater than the minimum distance from the lower side of the baffle plate 1301 to the circular shell 1303, the baffle plate 1301 is provided with a truncated cone hole 1304, the circular shell 1303 is used to block the truncated cone hole 1304, and the sliding column 1302 passes through the truncated cone hole 1304.

[0073] In the above scheme, the extrusion shell 1204 and the shielding plate 1301 are detachably connected to form a storage cavity for storing marking dust. The cross-sectional shape of the middle part of the shielding plate 1301 is an isosceles trapezoid, which is used to guide the marking dust to slide in the direction of the two oblique sides of the trapezoid. The sliding column 1302 is composed of two straight cylinders with different diameters. The straight cylinder with a smaller diameter in the sliding column 1302 is used to pass through the truncated cone hole 1304, and its diameter is smaller than the minimum diameter of the truncated cone hole 1304, which is used to ensure the outflow of the marking dust. The minimum diameter of the annular shell 1303 is the same as the maximum diameter of the truncated cone hole 1304, which makes it easy for the annular shell 1303 to block the truncated cone hole 1304. The diameter of the truncated cone hole 1304 gradually decreases from top to bottom, which is used to guide the discharge of materials. In the vertical direction, the minimum distance from the lower side of the sliding column 1302 to the annular shell 1303 is greater than the minimum distance from the lower side of the baffle plate 1301 to the annular shell 1303, which is used to ensure that the annular shell 1303 can block the truncated cone hole 1304.

[0074] When the fixing position of the surveying and mapping device is soft soil, the first arc plate 5 and the first squeezing plate 501 thereon squeeze the soil during the fixing process, leaving a rectangular pit in the soil that is more obvious than the pressure of the squeezing block 9, making it easier for the staff to notice and determine the surveyed position.

[0075] When the fixed position of the surveying and mapping device is compacted soil, during the fixing process, when the extrusion shell 1204 slides downward, the lower side of the sliding column 1302 gradually contacts the compacted soil, and then the sliding column 1302 slides upward relative to the baffle plate 1301 under the extrusion of the soil, and the baffle plate 1301 drives the adjacent circular shell 1303 to slide upward, and the circular shell 1303 releases the blockage of the adjacent truncated cone hole 1304, and the marking dust in the closed chamber composed of the extrusion shell 1204 and the baffle plate 1301 slides out of the closed chamber composed of the extrusion shell 1204 and the baffle plate 1301 along the truncated cone hole 1304, and falls on the ground to form dot-shaped punctuation marks. By marking different soil types in different ways, it is convenient for staff to observe the position after surveying and distinguish the properties of the surveyed soil.
