Description

Slope measuring instrument
The technical field is as follows:
the utility model belongs to the technical field of the road slope construction, concretely relates to side slope measuring instrument is applicable to the measurement of road bed and foundation ditch side slope.
Background art:
in the construction of road bed and foundation ditch, for guaranteeing road bed and foundation ditch stability, the domatic slope of having certain slope of making in its both sides is called the side slope, and road bed and foundation ditch side slope adopt certain angular design, effectively protect road bed and foundation ditch, simultaneously in order to reach the side slope requirement of construction design, the inevitable measurement to its slope, the measuring method of slope: one method is that a leveling instrument is used for measuring the local vertical height difference of the side slope, a steel ruler is used for measuring the horizontal distance of a plane, and then the slope value is calculated; although the method is accurate in measurement, the whole measurement calculation process is complex; the other method is that the total station is used for measurement, the monitoring accuracy of the total station is high, but the erection and the use of the instrument require special personnel, the process is long, and the instrument is obtained by utilizing trigonometric function calculation. Both of the above-mentioned measurement methods result in a slow measurement speed. There is therefore a need for a slope gradient measuring instrument that is simple and fast to operate.
The utility model has the following contents:
in order to overcome the deficiencies in the prior art, the utility model provides a simple structure, equipment convenience and portable's slope measuring instrument for measuring speed improves the efficiency of construction, practices thrift the cost.
The utility model provides a technical problem's technical scheme as follows:
a slope gradient measuring instrument comprises a straight ruler, a leveling tube and an indicating rod, wherein one end of the indicating rod is fixed on the straight ruler, and the other end of the indicating rod is a free end; the leveling tube is detachably connected with the ruler, the leveling tube is semicircular, angle scale marks are arranged on the outer surface of the leveling tube, liquid is filled in the leveling tube, a metal bubble is arranged in the leveling tube, and the interior of the metal bubble is in a vacuum state.
Further, the ruler comprises a first ruler and a second ruler, and the first ruler and the second ruler are symmetrically arranged in a folded mode.
Furthermore, a center line is arranged on the inner wall of the leveling pipe.
Further, the leveling tube is a transparent tube.
Compared with the prior art, the utility model following beneficial effect has: 1) the straight ruler is foldable, can be freely bent, and can be rotated and folded in the middle, so that the carrying is convenient; 2) the metal bubble arranged on the semicircular leveling tube floats on the liquid in the tube, so that the placing angle of the instrument can be simply and accurately measured; 3) simple structure, the equipment of being convenient for, convenient to use can accurately measure the side slope fast, improves measuring efficiency.
Drawings
The invention will be further explained with reference to the drawings and the detailed description below:
fig. 1 is the utility model relates to a side slope measuring instrument's schematic structure diagram.
The numbers in the figures are as follows: 1-a ruler; 11-a first straightedge; 12-a second straightedge; 2-a leveling tube; 3-a metal bubble; 4-indicating rod.
Detailed Description
Examples
As shown in fig. 1, a slope gradient measuring instrument comprises a straight ruler 1, a leveling pipe 2 and an indication rod 4, wherein the straight ruler 1 comprises a first straight ruler 11 and a second straight ruler 12, the first straight ruler 11 and the second straight ruler 12 are symmetrically folded and arranged, and are connected through a buckle. One end of the indicating rod 4 is fixed on the ruler 1, and the other end is a free end; the air level 2 with the connection can be dismantled to ruler 1, air level 2 is the semicircle ring shape, and its surface is equipped with the angle scale mark, and the indicator rod 4 can fix on ruler 1 and to the arbitrary angle scale mark of directive before calculating the design slope, air level 2 is inside to be full of liquid and to be provided with metal bubble 3, 3 inside vacuum states that are in of metal bubble, in order to be convenient for observe better, the colour of metal bubble 3 can set red to, be provided with a central line on 2 inner walls of air level, this central line is in order to further ensure the accuracy of slope measurement. When the ruler 1 is horizontally placed, the metal bubble 3 is positioned in the middle of the semicircular leveling tube 2, and the indicating rod 4 points to 0 degree; when the straightedge 1 is upright, the metal bubble 3 is located at one end of the semicircular leveling tube 2, and the indicating rod 4 points to 90 degrees. Preferably, the level tube 2 is a transparent tube, so that the position and flow position of the metal bubble 3 can be clearly and quickly seen. The utility model provides a 1 total length 1.0m of ruler, the annular radius of levelling pipe 2 is not more than 0.30m, convenient to carry. When in use, the electronic level is required to be corrected by a total station, and the two ends of the annular bubble are provided with correction electric screws for correcting the position of the level tube 2. In order to ensure the stability and accuracy of slope gradient measurement, the straight ruler 1 and the leveling pipe 2 are checked once a month, and in addition, the pressure prevention needs to be noticed in normal use.
The utility model discloses before using 1) calculate the angle that the slope of design corresponds earlier h/l ═ tg (α), α ═ arctg (h/l), 2) will be fixed in 4 screws of the guide bar on ruler 1 and loosen, then with the corresponding angle that guide bar 4 alignment calculation reachs and fix.
The utility model discloses the principle: and (3) abutting the straight ruler 1 against the slope, and adjusting the measuring instrument to enable the metal bubble 3 to coincide with the central line in the leveling tube 2. When the angle indicated by the metal bubble 3 is smaller than the angle indicated by the indicating rod 4, the actually measured gradient is slower than the designed gradient; when the angle indicated by the metal bubble 3 is larger than the angle indicated by the indicating rod 4, the measured gradient is steeper than the designed gradient, and the slope is repaired in the construction process according to the measurement result. When the angle indicated by the indicating rod 4 is superposed with the metal bubble 3, the actually measured side slope is the same as the designed side slope, namely the constructed side slope is qualified.
The utility model discloses simple structure, the equipment of being convenient for, convenient to use can accurately measure the side slope fast, improves the efficiency of measurement.
The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
The parts of the present invention not described in detail are the known techniques of those skilled in the art.
