Abstract
The utility model discloses a road slope ruler, which comprises a leading ruler with a scale and two brackets arranged at two ends of the leading ruler, wherein, a fixed bracket is arranged at one end of the leading ruler and a moveable bracket that can slide along the leading ruler is arranged at the other end thereof. An extension ruler is installed above the moveable bracket and a leveling tube is arranged on the top face of the leading ruler. The utility model is manufactured by utilizing a tangent value of triangle function, namely, a method of road slope; when in use, two brackets of the slope ruler are merely needed to be positioned on the measuring surface, and the slope value of the road can be measured by regulating the height of the extension ruler or sliding the extension ruler left and right, thus being very convenient to be used.
Description
Technical field:
The utility model relates to a kind of surveying instrument, especially a kind of road grade chi of the measurement road gradient.
Background technology:
The measurement of road grade is a requisite operation in the road construction, method at present commonly used is the vertical height that the method for utilizing horizontal scope and scale to combine is measured point-to-point transmission, and then calculate value of slope by the method for trigonometric function, measurements and calculations are all pretty troublesome, use very inconvenient.
The utility model content:
The purpose of this utility model provides road grade chi a kind of simple in structure, easy to use.
The technical solution of the utility model is: a kind of road grade chi, the main scale and two supports that are contained in its two ends that comprise a band scale, at one end head is equipped with a fixed support, a travel(l)ing rest that can horizontally slip along main scale is equipped with in another termination, one shrinkage-rule is housed above travel(l)ing rest, a 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.
The height of fixed support and travel(l)ing rest is 10cm.
The length of main scale is 200cm.
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 the measurement face during use, by the height of adjusting shrinkage-rule or the value of slope that the shrinkage-rule that horizontally slips just can be measured road, very easy to use.
Description of drawings:
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure vertical view.
Embodiment:
Structure of the present utility model as shown in Figure 1 and Figure 2, a kind of road grade chi, the main scale 2 and two supports that are contained in its two ends that comprise a band 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, and a shrinkage-rule 4 is housed above travel(l)ing rest, and a level tube 7 is housed on the end face of main scale, at fixed support and travel(l)ing rest lower end one tripod 5 is housed respectively, tripod 5 connects by hinge 6 with the support lower end.The height of fixed support 1 and travel(l)ing rest 3 is 10cm.The length of main scale 2 is 200cm.
Using method:
1, during the measurement road road gradient, grade rod is placed on the road surface, adjusts the height of shrinkage-rule 4, make the bubble in main scale 2 level tubes 7 placed in the middle, the reading on this moment shrinkage-rule 4 then is a value of slope.
When 2, measuring surface slope i=1:n, grade rod is placed on the inclined-plane, with the position of the height stuck-at-m of shrinkage-rule 4, the shrinkage-rule 4 that horizontally slips, when making bubble in the level tube 7 placed in the middle, the reading on the main scale 2 is the n value.
Claims (4)
1, a kind of road grade chi, it is characterized in that, the main scale and two supports that are contained in its two ends that comprise a band scale, at one end head is equipped with a fixed support, a travel(l)ing rest that can horizontally slip along main scale is equipped with in another termination, one shrinkage-rule is housed above travel(l)ing rest, a level tube is housed on the end face of main scale.
2, road grade chi according to claim 1 is characterized in that, at fixed support and travel(l)ing rest lower end one tripod is housed respectively, tripod and support lower end hinge-coupled.
3, road grade chi according to claim 1 and 2 is characterized in that, the height of fixed support and travel(l)ing rest is 10cm.
4, road grade chi according to claim 1 is characterized in that, the length of main scale is 200cm.
