Description

A kind of roadbed slope gradient measuring apparatus

Technical field

This utility model relates to gradient measurer equipment technical field, specifically a kind of roadbed slope gradient measuring apparatus.

Background technology

At present, the roadbed essential structure of highway is made up of three aspects, the width of roadbed, height and grade of side slope (being similar to the ratio of height in triangle and base), wherein grade of side slope depends on that geology and filling out of roadbed dig height, when side slope design grade once it is determined that, if it exceeds setting in construction, can bring about the economic problems of the increase of floor space and transverse section, if not reaching setting, all right stability directly affecting roadbed. Bury the hidden danger of quality, therefore, in construction, measure grade of side slope accurately, fast and efficiently, not only make roadbed side slope rapid shaping, save the effective working time, the stability of roadbed can be made again to be guaranteed, so measuring subgrade side slope gradient measuring equipment very important.

Utility model content

The purpose of this utility model is in that to provide a kind of roadbed slope gradient measuring apparatus, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme: a kind of roadbed slope gradient measuring apparatus, including gradient graduated disc, L-type bar, level indicator, motion bar, connect axle, first graduation mark and movable pointer, described gradient graduated disc is fixedly mounted on the left end of L-type bar, described gradient graduated disc is provided with the first graduation mark, described movable pointer is flexibly connected by pin with gradient graduated disc, described L-type bar is provided with level indicator, and level indicator is arranged on gradient graduated disc and is connected between axle, it is fixed with between described L-type bar and handle and is connected axle, described motion bar is fixing with pipe box to be connected, and motion bar is provided with the second graduation mark, described connection axle is flexibly connected by pipe box with motion bar.

Further, described connection axle and pipe box are rotationally connected by bearing.

Further, described handle is fixed on the right side connecting axle, and is provided with screw thread shape lines on handle.

Further, the left end of described connection axle is provided with external screw thread, and the right-hand member of L-type bar is provided with female thread, and L-type bar is threaded connection fixing connection with being connected axle.

Compared with prior art, the beneficial effects of the utility model are: this utility model utilizes movable pointer under gravity downward vertically, graduation mark on motion bar is parallel with roadbed side slope, by observing on gradient index dial on movable pointer and motion bar the angle between the second graduation mark, just can learn the tangent angle of grade of side slope, conversion by angle Yu ratio, just can obtain the gradient of side slope, the setting of level indicator, ensure in measurement process, equipment is in the state of level, ensure the preciseness measured, the setting of screw thread shape lines on handle, equipment is easy to carry about with one, motion bar, pipe box be connected axle with the use of, make the motion bar can 360 degree of rotations, equipment overall weight is light, it is easy to carry, measuring speed is fast, measurement numerical value is accurate, simple to operate, a people is only needed individually to complete, substantially increase the efficiency of work, measurement suitable in highway subgrade ramp.
