Abstract
The present invention relates to underground survey device technique field; particularly relate to a kind of underground top plate and measure control point; including copper bar and the control point round steel being connected on copper bar; copper bar and round steel junction, control point are welded with disk; the steel protection pipe of cylinder it is welded with on disk; steel protection pipe is positioned at round steel side, control point; steel protection pipe is identical with control point round steel axis; steel protection pipe end opening is concordant with round steel lower end, control point; this apparatus structure is simple; protection control point is from the impact of spray operation, it is ensured that surveying setting-out is working properly to be carried out.
Description
Technical field
The present invention relates to underground survey device technique field, particularly relate to a kind of underground top plate and measure control point.
Background technology
The measurement control point, tunnel of underground mines is all disposed within top board, because having pedestrian and haulage vehicle walking, control on base plate
System point is such as arranged on base plate, is easily destroyed, and is difficult to preserve.And top board needs to carry out spray operation, easy during spray operation
Control point will be measured destroy, and affect the work of normal surveying setting-out, thus affect the measurement operation of down-hole.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of underground top plate to measure control
Processed, protection control point, it is ensured that surveying setting-out is working properly to be carried out.
Underground top plate of the present invention measures control point, including copper bar and the control point round steel that is connected on copper bar, copper bar and
Round steel junction, control point is welded with disk, and disk is welded with the steel protection pipe of cylinder, and steel protection pipe is positioned at control
Point round steel side, steel protection pipe is identical with control point round steel axis, and steel protection pipe end opening is concordant with round steel lower end, control point.
Being provided with steel protection pipe outside the round steel of control point, protection control point round steel is not affected by spray operation, thus be ensure that
Being normally carried out of surveying setting-out work.
A diameter of 8cm-10cm is managed in described steel protection.
Described disk diameter is 13cm-15cm, reserves welding heat affected zone.
The present invention is compared with prior art had the beneficial effect that
Underground top plate measures control point simple in construction, and protection control point is from the impact of spray operation, it is ensured that surveying setting-out
Working properly carry out.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
In figure: 1, copper bar；2, disk；3, control point round steel；4, steel protection pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described further:
As it is shown in figure 1, underground top plate measures control point, including copper bar 1 and the control point round steel 3 being connected on copper bar 1,
Copper bar 1 and control point round steel 3 junction are welded with disk 2, and disk 2 is welded with the steel protection pipe 4 of cylinder, steel
Protection pipe 4 is positioned at control point round steel 3 side, and steel protection pipe 4 is identical with control point round steel 3 axis, steel protection pipe 4
End opening is concordant with control point round steel 3 lower end.
Steel the protection a diameter of 8cm of pipe 4, a diameter of 13cm of disk 2.
During use, copper bar 1 inserts back, reserves control point round steel 3 unwrapping wire use, welds outside control point round steel 3
Steel is had to protect pipe 4, protection control point round steel 3 not to be affected by spray operation, thus ensure that surveying setting-out is just working
Often carry out.
