Description
Technical field
The utility model belongs to Tunnel construction survey device, is specifically related to borehole verify device.
Background technology
The work of constructing tunnel out break is the key factor affecting engineering cost, and working-yard needs, by controlling the spacing of periphery hole and the angle of its outer limb, to realize the control to out break.In prior art, the spacing of periphery hole is easily controlled by surveying setting-out or dipstick metering, but the surveying work of its outer limb is more difficult carries out, and how simply to be judged by operating experience.
Utility model content
The purpose of this utility model is to provide a kind of borehole verify device, and the utility model structure is simple, designs ingenious, accurately can measure the outer limb of borehole.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Borehole verify device, described verify device comprises hinged station meter and inspecting hole bar, and the station meter of hinged place is also installed with protractor, and the base of protractor is vertical with station meter, and described inspecting hole bar is expansion link, and station meter is provided with spirit level.
Preferably, described expansion link comprises hollow stem and solid hopkinson bar, hollow stem end and station meter hinged, and hollow stem is provided with the arrow pointing to protractor arc-shaped side.
Preferably, the arc-shaped side of described protractor is provided with angle index, and the scale mark reading on vertical base is 0 °, and the scale mark reading on parallel base is 90 °.
Preferably, when described station meter and inspecting hole bar are in parastate, arrow points to 0 ° of scale mark.
Preferably, described station meter is connected with adjustable ruler Vertical movements by screw, and the scale on adjustable ruler is 0-10cm.
Outer limb is the angle of borehole axis and line direction, and in actual job, tunnel contour face needs supporting, and a mask is longitudinally general parallel with line direction.
When a mask is smooth, station meter is directly near a mask.Station meter is namely parallel with line direction.Inserted in borehole by inspecting hole bar, arrow direction is borehole axis direction this moment, if borehole is comparatively dark, the solid hopkinson bar of inspecting hole bar can be extracted out to extend inspecting hole pole length from hollow stem.Insert after borehole until inspecting hole bar, regulate the position of station meter, make spirit level be in horizontality, on the hollow stem now reading inspecting hole bar, arrow points to the reading of protractor scale, and this angle is the outer limb angle of this borehole.
When a mask out-of-flatness, directly near propping up, mask is general and line direction is not parallel for station meter.Need to be regulated station meter by the super deficient measurement data of the section of supporting, it is made to be parallel to line direction: rear supporting of being conflicted by adjustable ruler, according to the super deficient measurement data of the section of rear supporting, by the relative position of screw secured adjusted chi and station meter, station meter is made to be parallel to line direction, on the hollow stem of reading inspecting hole bar, arrow points to the reading of protractor scale, and this angle is the outer limb angle of this borehole.
Be no more than 5cm because supporting specification regulation is maximum, therefore the scale of adjustable ruler designs according to effective length 10cm.
The utility model may be used for excavation training in advance and on-the-spot boring front simulation uses, and also can be used for cut hole Angle ambiguity.
Compared with prior art, tool has the following advantages the utility model:
1) inspecting hole pole length is adjustable, can regulate length according to actual needs, carries out coordinating insert with borehole;
2), when the outer limb of the tunnel borehole that a mask is smooth being measured, can, by the bubble and scale that station meter arranges, make station meter find level accurately fast, improve and measure efficiency;
3) when the outer limb of a mask irregular tunnel borehole is measured, by the super deficient measurement data of the section of adjustable ruler comparison supporting, make station meter find line direction accurately fast, improve measurement efficiency and the precision of the outer limb of borehole.
