Abstract

The utility model provides a roadbed slope gradient measuring apparatus, comprising a pulling-out ruler rod, a standard ruler rod, a spirit bubble and a standard vertical ruler, wherein the standard vertical ruler and the standard ruler rod are members of the main body of the utility model, the standard vertical ruler is connected with one end of the standard ruler rod, forming a right angle rule. The standard vertical ruler is fixed in vertical direction, and the standard ruler rod si fixed in horizontal direction. The spirit bubble for levelling is fixed on the upper surface of the standard ruler rod, basically in the middle, that is graduation representing concrete dimension is fixed on the upper surface of the standard ruler rod. The standard ruler rod is hollow, the pulling-out ruler rod is fixed in, another pulling-out ruler rod is fixed in the pulling-out ruler rod, in general at least tow sections are fixed, for making the leveller becoming three sections; the pulling-out ruler rod may be four sections as required, for making the leveller becoming five sections. The apparatus of the utilty model can be completed by one preson, the result can be read immediately without calculation and table search, thereby greatly raising working efficiency.

Description

The roadbed side slope gradient measurer

Technical field:

The utility model relates to a kind of instrument in the easy measurement roadbed side slope gradient of highway industry energy, does not need computation of table lookup just can detect the roadbed gradient easily, sees whether it adheres to specification.

Background technology:

At present, known roadbed side slope slope detection is explained with a ratio in fact in the highway field, and as 1: 2,1: 2.5,1: 3 form of presentation such as grade was not to be an angle.Two kinds of common measuring methods are arranged, generally need two people to cooperate to carry out when the first is measured, a people draws steel tape or measures the side slope horizontal length with two meters bars, and another people measures the vertical height of side slope, inconvenient and measure inaccurate, last result and can not intuitively find out whether adhere to specification.Second method is to use the measurement of angle instrument to measure the angle of the gradient, looks into the angle table then and calculates the roadbed gradient, and it is not directly perceived to calculate trouble.All there is the not high problem of efficient in these two kinds of methods, can not draw the detection conclusion very soon in the scene.

The utility model content:

The purpose of this utility model is, overcomes the deficiencies in the prior art part, and especially detection method is not accurate enough, can not intuitively reach a conclusion, the problem that efficient is not high has proposed a kind of roadbed side slope gradient measurer, can directly draw the gradient fast without calculating, see whether it adheres to specification.

Roadbed side slope gradient measurer described in the utility model, include and pull out the perpendicular chi composition of chi bar, station meter bar, spirit bubble and benchmark, perpendicular chi of said benchmark and station meter bar are main components of the present utility model, one end of perpendicular chi of benchmark and station meter bar is connected, and becomes the form that turns chi at right angle.Vertically disposed is the perpendicular chi of benchmark, horizontally disposed station meter bar.On the upper surface of station meter bar, in position placed in the middle substantially, be provided with the spirit bubble that lining is used, also be on the upper surface of station meter bar, be provided with the scale of the concrete size of expression.Empty structure in said station meter bar of the present utility model is set to is provided with in the station meter bar and pulls out the chi bar, said pull out to be provided with again in the chi bar pull out the chi bar, two joints generally should be set at least pull out the chi bar, make surveyor's staff become the forms of three joints; If real work needs, pull out the chi bar and also can be arranged to four joints, make surveyor's staff become the form of five joints.

The beneficial effects of the utility model are, can a people separately operation finish, the result needn't calculate, and also needn't table look-up and ask for, and can read immediately, on-the-spotly judges that whether the gradient meets design requirement, and has improved work efficiency greatly.

Embodiment:

Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: roadbed side slope gradient measurer described in the utility model, include and pull out perpendicular chi 4 compositions of chi bar 1, station meter bar 2, spirit bubble 3 and benchmark, perpendicular chi 4 of said benchmark and station meter bar 2 are main components of the present utility model, one end of perpendicular chi 4 of benchmark and station meter bar 2 is connected, and becomes the form that turns chi at right angle.Vertically disposed is the perpendicular chi 4 of benchmark, horizontally disposed station meter bar 2.On the upper surface of station meter bar 2, in position placed in the middle substantially, be provided with the spirit bubble 3 that lining is used, also be on the upper surface of station meter bar 2, be provided with the scale of the concrete size of expression.The structure of sky in said station meter bar 2 of the present utility model is set to, be provided with in the station meter bar 2 and pull out chi bar 1, said pull out to be provided with again in the chi bar 1 pull out chi bar 1, generally should be provided with at least two the joint pull out chi bar 1, make surveyor's staff become three the joint forms; If real work needs, pull out chi bar 1 and also can be arranged to four joints, that just pulls out four joints pulls out chi bar 1, makes surveyor's staff become the forms of five joints.The technical scheme that its technical matters that solves the utility model adopts is: one can pull duralumin matter station meter bar 2, xsect is 2cm * 4cm rectangle, that pulls out from station meter bar 2 pulls out chi bar 1, but 50 centimetres of each maximum pull lengthenings, outmost ruler scale is display scale 0-100 centimetre from left to right, minimum resolution calibration is 1 millimeter, but top scale represents it is 2 times of actual scale, 1 centimetre that is about to reality is expressed as 2 centimetres, actual 2 centimetres are expressed as 4 centimetres, by that analogy, the 50th centimetre of reality is 100 centimetres.The plane is provided with a spirit bubble 3 parallel with station meter bar 2 on the station meter bar 2, can conveniently find out whether horizontal positioned of this chi, and the slide rail of groove as the perpendicular chi 4 of another perpendicular crossing benchmark made at station meter bar 2 edges.Other has the perpendicular chi 4 of the duralumin matter benchmark of one 50 centimeter length to intersect vertically by slide rail and horizontally disposed station meter bar 2.When measuring the roadbed gradient, 1 people operation gets final product, place on the vertical road surface of ruler that at first can pull, but be not to want level, the people walks downward along side slope, pull out while walking and to pull out chi bar 1, pull out chi bar 1 and should guarantee once completely to pull out 50 centimetres, carry out WidFin during station meter bar 2 basic horizontal again.Marginal not meaning spirit bubble 3 during fine setting, limit move left and right benchmark erects chi 4, and up to the perpendicular chi 4 bottoms contact of benchmark side slope, spirit bubble 3 levels are promptly adjusted and are finished simultaneously.At this time, left side, the position numerical value that intersects according to perpendicular chi 4 of benchmark and station meter bar 2, read the scale reading on the station meter bar 2, add the ruler quantity that pull comes out, promptly suppose pull two rulers that come out, the reading of station meter bar 2 is 18 centimetres, and physical length is half of reading, then be 2.18 meters, then grade of side slope then is 1: 2.18.Can judge at once whether it meets design requirement.The beneficial effects of the utility model are, can a people separately operation finish, the result needn't calculate, and also needn't table look-up and ask for, and can read immediately, on-the-spotly judges that whether the gradient meets design requirement, and has improved work efficiency greatly.
