Lane surface displacement often adopts cross distribution point method to install monitoring section, at tunnel roof and floor middle part, direction and two is helped horizontal direction boring, four hole journey crossing distribution at grade, in hole, squeeze into stopper, on stopper, hammer into iron nail, as datum mark, be mainly used in observing after roadway excavation roof-to-floor convergence and two help the amount of shifting near over time with development.
Down-hole adopts steel tape to carry out the measurement of lane surface displacement mostly at present, often occurs following problem in actual measurement:
1, steel ruler contrast locating is more difficult, and while measurement especially in the vertical direction, steel ruler top is difficult to navigate to fast the datum mark of having established, and often needs two people or multiple people jointly to complete, and wastes time and energy.2, while carrying out the displacement measurement of horizontal direction easily there is bending in steel tape, thereby affect measuring accuracy.
As can be seen here, prior art needs further improvement and develops.
Utility model content
The utility model provides a kind of mining flexible sounding rod for solving above-mentioned defect of the prior art, this sounding rod can be located datum mark fast in measuring process, time saving and energy saving, and flexible sounding rod there will not be bending, and measuring accuracy is far away higher than tape measure.
For solving the problems of the technologies described above, the utility model scheme comprises:
A kind of mining flexible sounding rod, the lower end of this sounding rod is designed to fixing loop bar, and the upper end of loop bar is positive hexagonal structure, and a pilot hole is set.
Preferably, connection expansion link on fixing loop bar, expansion link is all designed to positive hexagonal structure, the upper end of penetralia expansion link arranges a pole cap, lower end arranges a location ball, the two ends up and down of other expansion links except penetralia expansion link arrange respectively pilot hole and location ball, and location ball and pilot hole are arranged on same straight line.
Further, be provided with scale mark on expansion link, scale starts marking from the top of penetralia expansion link pole cap, is outwards successively connected marking, and ensures the accuracy that between each expansion link, scale mark is connected.
Further, be provided with the magnet for locating in the fixing loop bar lower end of sounding rod with the upper end of the expansion link that pole cap is set.
Useful technique effect of the present utility model is:
The mining flexible sounding rod of one that the utility model provides, survey crew is in the time using this sounding rod, in fixing loop bar, pull out section by section expansion link, and allow location, the expansion link lower end ball of pull-out be connected and fixed with next section telescopic bar upper end pilot hole to be pulled out, until move needed length to, at this moment operating personnel shift near sounding rod top near the iron nail of datum mark, under the effect of magnetic force, sounding rod top can navigate to rapidly reference point, then finely tune expansion link, the scale mark that observation is alignd with fixing loop bar upper end carries out reading, reading adds that the length of fixing loop bar is exactly needed data.Surveyed latter one and held fixing loop bar, another holds expansion link, expansion link is shunk one by one and be inserted in fixing loop bar.Aforesaid operations process is simple, and a people just can position measurement to datum mark easily, time saving and energy saving, and in measuring process, flexible sounding rod there will not be bending, and measuring accuracy is high.
