Abstract

Provided is a dip meter for a peripheral blast hole of a tunnel, and the dip meter is characterized by comprising a mark post (1) and a protractor (5) integrated with the mark post; and a side of the mark post is a long and straight polished rod extending from the protractor (5), a base of the semicircular protractor (5) is parallel with the middle axle of the mark post (1), a pointer rotating shaft (2) is disposed at the center of the circle of the semicircular protractor (5), and a pointer (3) used for pointing angles is movably sleeved on the pointer rotating shaft (2). When the mark post inclines, an angle between the pointer (3) and a scale of 0 degree is an angle of inclination of a tested peripheral blast hole. The dip meter for the peripheral blast hole of the tunnel is simple in structure, small in size, light in weight, convenient to carry and easy to operate, and has high measurement accuracy for execution of the blast hole in a tunnel construction site, producing a comparatively good guiding significance in sits for controlling an external angle of the peripheral blast hole in each deep cycle. And back break of the tunnel can be controlled directly, quality of excavation is ensured, cost of tunnel engineering is reduced, and a construction period is shorted.

Description

A kind of tunnel perimeter big gun hole drift indicator
Technical field
The utility model relates to the tunnel construction instrument, is a kind of tunnel perimeter big gun hole drift indicator specifically.
Background technology
At first the tunnel smooth Surface Blasting Technology is to control the drilling quality of periphery hole, guarantee excavation rear perimeter edge profile is smoother smooth, so how effectively control the borehole accuracy of periphery hole, the outer limb that guarantees the periphery hole of each circulation by design is the gordian technique of Tunnel Engineering explosion, outer limb and directly affect the out break in tunnel, guarantee excavation quality, reduce the Tunnel Engineering cost, save the duration.Construction in the past is all to rely on the outer limb of eyes or experience keyhole to be difficult to guarantee the precision of outer limb, and the degree of tilt of outer limb is to change with different drilling depths, so the periphery hole inclination angular instrument that the simplicity of design operation is easily gone has very large promotional value.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple to operate, the sensitive reliable tunnel perimeter big gun of precision hole drift indicator.
Described tunnel perimeter big gun hole drift indicator, it is characterized in that: comprise that mark post reaches and the protractor of described mark post one, described mark post one side is to stretch out the straight shape polished rod of length of described protractor, the base of semicircular described protractor is parallel with the axis of described mark post, home position at semicircle protractor is provided with pointer shaft, and movable sleeve is connected to the pointer of making angular marking on described pointer shaft.
As prioritization scheme, from the initial mark post scale that is provided with of the polished end of described mark post.
As prioritization scheme, at the free end of described pointer, be provided with weight.
The utility model is simple in structure, and volume is little, lightweight, be easy to carry, and is easy to operation, and the measuring accuracy that applies for the big gun hole of tunnel construction site is high, for control each deeply outer limb of the periphery hole of circulation on-the-spot guidance meaning is preferably arranged.Directly have influence on the out break in tunnel, guarantee excavation quality, reduce the Tunnel Engineering cost, and save the duration.
The accompanying drawing explanation
Fig. 1 is the utility model one-piece construction schematic diagram,
Fig. 2 is application state schematic diagram of the present utility model.
In figure: 1-mark post, 2-pointer shaft, 3-pointer, 4-90 ° of scales, 5-protractor, 6-0 ° of scale, 7-angle index, 8-mark post scale, 9-tunnel light face, 10-big gun bar, 11-drift indicator, 12-weight.
Embodiment
The present invention is further described below in conjunction with accompanying drawing: as shown in fig. 1, described tunnel perimeter big gun hole drift indicator, comprise that mark post 1 reaches and the protractor 5 of described mark post one, described mark post one side is to stretch out the straight shape polished rod of length of described protractor 5, from the initial mark post scale 8 that is provided with of the polished end of described mark post 1.The base of semicircular described protractor is parallel with the axis of described mark post 1, at the home position of semicircle protractor, is provided with pointer shaft 2, and movable sleeve is connected to the pointer 3 of making angular marking on described pointer shaft 2.Free end at described pointer 3 is provided with weight 12.
In the circular edge of protractor 5, indicate angle index 7, the vertical base scale mark of protractor is 0 ° of scale 6, and the scale mark parallel with base is 90 ° of scales 4.When the protractor plane is vertical or approach when vertical, pointer 3 can keep vertically and point to 6 under the effect of weight 12.When mark post tilted, pointer was pointed out angle of inclination on the scale plane of protractor.
In work progress, as Fig. 2, adopt laser orientation instrument to point to and carry out the section unwrapping wire, arranging driller tradesman to carry out the vault eye and creep into.After the vault eye bores at the horizontal mark post 1 of big gun bar 10 1 end half insertion, requiring big gun hole axle to be parallel to the mark post direction creeps into, use the utility model drift indicator 11 to carry out periphery hole extrapolation angular measurement, the angle of inclination that can accurately read big gun bar 10 by the pointed scale fast.

Claims (3)

1. tunnel perimeter big gun hole drift indicator, it is characterized in that: comprise that mark post (1) reaches and the protractor (5) of described mark post one, described mark post one side is for stretching out the straight shape polished rod of length of described protractor (5), the base of semicircular described protractor is parallel with the axis of described mark post (1), home position at semicircle protractor is provided with pointer shaft (2), at the upper movable sleeve of described pointer shaft (2), is connected to the pointer (3) of making angular marking.
