Abstract
The utility model discloses a novel road slope scale. The novel road slope scale comprises a main scale with scales, a fixed bracket and a movable bracket; the novel road slope scale is characterized in that an extension scale is arranged above the movable bracket; a leveling tube is arranged on the top surface of the main scale; a triangular frame is arranged at the lower end of the fixed bracket and the lower end of the movable bracket, respectively; and the triangular frames are connected with the lower ends of the brackets by hinges.
Description
Technical field
The utility model relates to a kind of surveying instrument, especially a kind of a kind of new road grade rod of the measurement road gradient.
Background technology
The measurement of road grade is requisite operation in road construction, method commonly used is that the method for utilizing horizontal scope and scale to combine is measured 2 vertical heights of asking at present, and then calculate value of slope by the method for trigonometric function, measurements and calculations are all pretty troublesome, use very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, a kind of new road grade rod easy to use.
The technical solution of the utility model is: a kind of new road grade rod, consisted of by a main scale with scale, fixed support, travel(l)ing rest, it is characterized in that: a shrinkage-rule is housed above travel(l)ing rest, one level tube is housed on the end face of main scale, at fixed support and travel(l)ing rest lower end, one tripod is housed respectively, tripod and support lower end hinge-coupled.
Description of drawings
Fig. 1 is the structural representation of a kind of new road grade rod of the utility model;
1. fixed supports in figure, 2. main scale, 3. travel(l)ing rest, 4. shrinkage-rule, 5. tripod, 6. hinge, 7. level tube.
Embodiment
A kind of new road grade rod, comprise one with the main scale 2 and two supports that are contained in its two ends of scale, at one end head is equipped with a fixed support 1, a travel(l)ing rest 3 that can horizontally slip along main scale is equipped with in another termination, one shrinkage-rule 4 is housed above travel(l)ing rest 3, a level tube 7 is housed on the end face of main scale 2.At fixed support 1 and travel(l)ing rest 3 lower ends, a tripod 5 is housed respectively, tripod 5 connects with support lower end hinge 6.
The utility model is that the method for utilizing the tangent value of trigonometric function to be road grade is made, two supports of grade rod need only be placed on measurement face during use, just can measure the value of slope of road by height or the shrinkage-rule that horizontally slips of adjusting shrinkage-rule, very easy to use.
Claims (1)
