Description

Technical Field

[0001] The utility model relates to the technical field of land surveying, in particular to a positioning benchmark for national land space planning. Background Art

[0002] Land surveying is the work of measuring and mapping the quantity, distribution and topography of various types of land using surveying and remote sensing technology. It includes topographic surveying, cadastral surveying, land leveling surveying, land use status surveying, and reserve resource surveys such as barren hills and wastelands. The surveying methods used include geodetic surveying, general surveying, aerial photogrammetry, remote sensing technology, and map compilation. With the gradual completion of the national basic topographic map, land surveying mainly refers to other contents other than topographic surveying, and all are measured based on the national basic topographic map. The existing positioning poles mostly use direct insertion positioning poles, and the positioning poles are vertically inserted into the soil layer. In order to prevent the positioning pole from deviating, a bracket is often supported on the outside of the positioning pole. When the soil layer is relatively soft, the insertion depth of the positioning pole increases. At this time, after the bracket is erected, the angle between the bracket and the positioning pole is large, and the role it can play will be greatly reduced. Therefore, a positioning pole for national land space planning is designed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5The utility model provides a technical solution: a positioning benchmark for land space planning, comprising: a benchmark body 1 which is hollow inside and open at the upper end, a pointed cone 2 is connected to the lower end of the benchmark body 1, a secondary benchmark 3 is inserted into the benchmark body 1, a clamping block 4 is connected to the outer side of the upper end opening of the benchmark body 1 in a ring array, a thread is provided on the outer side of the clamping block 4, the clamping block 4 is inclined at one to two degrees from the lower end to the upper end, the inner diameter of the clamping block 4 is the same as the outer diameter of the secondary benchmark 3, a fixing ring 10 is sleeved on the outer side of the clamping block 4, the fixing ring 10 is connected to the outer sides of four clamping blocks 4 by threads, and the benchmark body The lower end of the inner wall is provided with four T-shaped slide grooves 5 in an array shape, a slider 6 having the same transverse cross section as the slide groove 5 is inserted into the slide groove 5, a threaded hole is provided in the middle of the slider 6, a mounting plane is provided around the outer side of the benchmark body 1 and located on one side of the slide groove 5, a bolt 7 is provided on the outer side of the slider 6, the bolt 7 is connected to the threaded hole provided in the middle of the slider 6 through a thread, the length of the bolt 7 is shorter than the thickness of the slider 6, an extension plate 8 is connected to the lower end of the slider 6, a support bracket 9 is rotatably connected to the end of the extension plate 8, a chamfer is provided at the end of the support bracket 9, and the connection between the support bracket 9 and the extension plate 8 is connected through a damping shaft.

[0025] When in use, move the national land space planning positioning pole to the desired position, insert it downward, and when it reaches the desired depth, loosen the bolt 7, pull down the support bracket 9 and the extension plate 8, and insert the support bracket 9 into the soil layer. Then tighten the bolt 7, and the slider 6 is locked inside the slide 5, thereby fixing the position of the support bracket 9. Then pull the secondary pole 3 upward, and when it is pulled to the desired height, hold the secondary pole 3 with one hand, and rotate the fixing ring 10 upward with the other hand. When the fixing ring 10 rotates upward, the clamping block 4 will squeeze inward to clamp the secondary pole 3 because the outer side from the lower end to the upper end is at an angle of one to two degrees. When the soil is relatively soft and the insertion depth of the pole body 1 needs to be increased, the bolt 7 can be loosened, the position of the slider 6 can be adjusted, and the support bracket 9 can be supported downward to ensure that the support bracket 9 can play a supporting role.

[0026] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the benchmark body 1, the pointed cone 2, and the auxiliary benchmark 3 are all made of steel, and the lower end of the pointed cone 2 is made of alloy steel.

[0027] From the analysis of the above structure, it can be seen that the benchmark body 1, the pointed cone 2, and the auxiliary benchmark 3 are all made of steel with a relatively hard texture, which can reduce the damage caused by friction, while the pointed cone 2 will be subjected to greater force at the lower end. The lower end of the pointed cone 2 is made of alloy steel with high hardness and is not easy to wear.

[0028] like Figure 1-5As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a rubber protection pad 21 is connected to the inner side of the clamping block 4 close to the auxiliary marker 3, and the rubber protection pad 21 is inclined at one to two degrees from top to bottom.

[0029] Analysis of the above structure shows that when the secondary marker 3 is clamped by the clamping block 4 , the rubber protective pad 21 will block the clamping block 4 to prevent the clamping block 4 from directly contacting the secondary marker 3 and causing the outer surface of the secondary marker 3 to be crushed.

[0030] like Figure 1-5 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, an arc slip ring 22 is connected to the outer side of the lower end of the auxiliary marker 3, and an arc slip ring 22 is also connected to the inside of the upper end opening of the marker body 1.

[0031] From the analysis of the above structure, it can be seen that the arc slip ring 22 around the outer side of the lower end of the auxiliary benchmark 3 and the arc slip ring 22 inside the opening of the upper end of the benchmark body 1 can reduce the contact area between the auxiliary benchmark 3 and the inside of the benchmark body 1, reduce friction, and also prevent the inside of the benchmark body 1 and the outer surface of the auxiliary benchmark 3 from being scratched.

[0032] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the left and right sides of the upper end of the benchmark body 1 are connected with push-down handles 23, and the outer side of the end of the push-down handle 23 is provided with an anti-slip sleeve.

[0033] From the analysis of the above structure, it can be seen that when positioning and inserting the positioning pole for national land space planning, the downward pressure handles 23 connected to the left and right sides of the upper end of the pole body 1 can be used to press downward, and the anti-slip sleeve provided on the outer side of the end of the downward pressure handle 23 can increase the friction.

[0034] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the outer surfaces of the benchmark body 1, the pointed cone 2 and the auxiliary benchmark 3 are all provided with a wear-resistant and waterproof coating.

[0035] Analysis of the above structure shows that the wear-resistant and waterproof coating on the outer surfaces of the benchmark body 1, the pointed cone 2 and the auxiliary benchmark 3 can reduce the friction loss between the benchmark body 1, the pointed cone 2, the auxiliary benchmark 3 and the sand and gravel inside the land, and prevent rust at the same time.

[0036] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the outer sides of the benchmark main body 1 and the auxiliary benchmark 3 are marked with scales.

[0037] From the analysis of the above structure, it can be seen that after the main body of the marker 1 is inserted into the ground, the auxiliary marker 3 is pulled out, and the height from the upper end of the positioning marker for national land space planning to the ground can be judged by observing the scale marked on the outside.
