Description

Technical Field

[0001] The utility model relates to the technical field of underground measuring devices, in particular to an underground measuring control point marker. Background Art

[0002] The underground measurement control points are generally arranged on the top of the tunnel and goaf. There is no standard control point mark at present. There are many ways to use it in practice, such as using split pins, bending iron nails, or using stainless steel sheets (with small holes on the bottom). The above-mentioned point marks have the following disadvantages: large point error, unclear point position, inconsistent point positions after multiple hanging lines, and certain errors in the height measurement position; the point mark is not obvious and not easy to find, and is often damaged in the subsequent construction of the top plate; the hanging line must use ladders and other climbing equipment, which is inconvenient; the marks made of non-stainless steel are easily corroded and damaged, etc.

[0003] Due to the above defects of the commonly used control point signs, technicians in this field have designed a control point sign: using duplex stainless steel (magnetic and corrosion-resistant) material; punching a hole in the center of the bottom (hole diameter 1mm); spraying red paint on the magnetic position at the bottom (hollow words: control point is strictly prohibited from being destroyed).

[0004] The installation and layout method of the control points is the same as the previous conventional method. Special attention should be paid to the fact that the control point marks should be pointed vertically downward as much as possible during layout, and the inclination should not exceed 45 degrees. After the points are laid out, if there are ladders and climbing equipment during measurement, the vertical line can be directly passed through the large threading hole and the small threading hole, and the tail can be knotted and fixed. The plumb ball can be hung at the point where the line passes through the small hole. The point position error is less than 1 mm. When the magnetic adsorption plumb ball is used in conjunction with it, the magnetic adsorption head can be clamped with a telescopic rod to align with the bottom of the control point mark, and it is automatically adsorbed by magnetism, thereby eliminating the need for ladders or other climbing equipment, and the point accuracy is basically the same.

[0005] Although the above device is good, there are still problems in actual use: that is, it is difficult to ensure that the sign is nailed in horizontally when hammering, and there is a risk that the sign head is easily deformed after being hit. Utility Model Content
