Abstract
The utility model provides a kind of underground coal mine measurement to lay permanent point, comprise copper stake, the one end side of copper stake is welded with the special nut of anchor pole, nut is connected with anchor pole head, the cylinder of the other end has a groove, bottom land is a plane, has a through hole between bottom land and another end face of copper stake.Permanent measurement point of the present utility model makes simple, and draw materials conveniently, method for embedding is reasonable, and not easily corrosion., on the tunnel of, roof cracking poor especially at geological environment or uncompacted back, link together with anchor pole meanwhile, can be more firm.
Description
Technical field
The utility model relates to underground coal mine field of measuring technique, particularly relates to
oneplant underground coal mine measurement and lay permanent measuring point.
Background technology
Coal mine survey is normally produced for the excavation in tunnel, the through of mine and coal and is ensured that the life security of staff all has great importance, and is called as " eyes " of coal production.The developing measurement of coal mine roadway provides construction center and stringcourse, and surveying setting-out has very important effect to guarantee and raising construction quality.So the preservation of measuring permanent control point is extremely important, the survey mark in complicated tunnel is often easily unstable or destroyed, delays construction speed.The time length that in unstable tunnel, survey mark is preserved directly has influence on construction speed and quality.Underground survey point is the basic facilities that roadway opening is measured, and survey mark is embedded in back more.Due to the moist many water in down-hole, and have acidity effect, use iron sticks up easily rotten tactile raw embroidery; Use survey nail bury underground very shallow, because of tunnel decoration and repair easily wreck, not easily preserve, do not have the effect of permanent survey mark.Once survey mark damages, will take the production time buries point observation again, can bring impact to coal production.Meanwhile, because shaft building project is in mountain area and desert mostly, make and buy permanent stake point inconvenient.
Utility model content
The technical problems to be solved in the utility model is that providing a kind of makes simple, the permanent measuring point of underground coal mine measurement easily of drawing materials laying, to solve prior art Problems existing.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Permanent point is laid in a kind of underground coal mine measurement, and comprise copper stake, the one end side of copper stake is welded with the special nut of anchor pole, nut is connected with anchor pole head, the cylinder of the other end has a groove, bottom land is a plane, has a through hole between bottom land and another end face of copper stake.
Fish pearl glue is scribbled, chromium plating on described nut external surface in described nut.
Permanent measurement point of the present utility model makes simple, and draw materials conveniently, method for embedding is reasonable, and not easily corrosion., on the tunnel of, roof cracking poor especially at geological environment or uncompacted back, link together with anchor pole meanwhile, can be more firm.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 and detailed description of the invention, the utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of underground coal mine measurement to lay permanent point, comprise copper stake 1, the one end side of copper stake 1 is welded with the special nut of anchor pole 2, nut 2 is connected with anchor pole head, increases the steadiness of permanent point, the cylinder of the other end has a groove 3, bottom land is a plane, has a through hole 4 between bottom land and another end face of copper stake.
Nut 2 screw thread scribbles fish pearl glue, makes tightening of anchor pole and nut more firm, chromium plating on nut 2 external surface.Can anticorrosion.
The size of copper post is selected as required, and the diameter range usually selecting copper stake is 18mm ~ 20mm, and length is about 300mm.
Permanent measurement point of the present utility model makes simple, and draw materials conveniently, method for embedding is reasonable, and not easily corrosion., on the tunnel of, roof cracking poor especially at geological environment or uncompacted back, link together with anchor pole meanwhile, can be more firm.
