Description
Technical field
The utility model relates to a kind of project supervision with detecting utensil, relates in particular to a kind of project supervision modified grade rod.
Background technology
What the grade of side slope of highway subgrade depended on geology, hydrologic condition and roadbed fills out excavation height, once the design grade of side slope determine, if exceed setting in construction, can cause the increase of floor area and the financial cost problem of transversal section.If do not reach setting, can directly affect the stability of roadbed, bury hidden danger of quality, therefore in construction, the Measurement accuracy of roadbed grade of side slope can not only make side slope rapid shaping, saves the engineering time, and can make the stability of roadbed effectively be ensured.When at present roadbed grade of side slope measurement, mostly be and will lean against in side slope with the ruler of gradient display disc, then read value of slope from gradient display disc.This metering system is had relatively high expectations to the flatness on side slope surface, have once side slope surface uneven, will make measurement result produce very large error.And side slope is difficult to the flatness situation that reaches desirable in reality construction, therefore above-mentioned metering system has larger limitation.
Utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of project supervision modified grade rod, it can realize the measurement to roadbed grade of side slope, and the measuring error that can avoid common grade rod to come because of Slope leveling degree difference band in use, has good practicality.
For achieving the above object, project supervision of the present utility model comprises the gradient indicator that is arranged on main scale middle part with modified grade rod, at the telescopic end chi that is provided with in the two ends of main scale, the one end of stretching out main scale at two end chis is provided with support, and on the end chi at main scale and two ends, being also provided with can be along the flatness testing agency of main scale and the slip of end chi.Adopt above-mentioned technical scheme, in the time measuring the roadbed side slope gradient, the distance of first stretching out main scale according to the width adjustment end chi of side slope, again flatness testing agency is slid into the support place of a side chi, then the support on two end chis is placed in respectively to the edge up and down of roadbed side slope, again flatness testing agency is slided to the other end of grade rod by placed one end, the slope height at that end support place that the flatness situation adjustment flatness testing agency on the side slope surface detecting according to flatness testing agency in the process of sliding slides to, and finally make main scale and hold chi substantially parallel with side slope surface, the grade of side slope of measuring is thus numerical value comparatively accurately.
As the restriction to aforesaid way, described flatness testing agency comprises the chute being arranged on main scale and end chi both sides end face, slides and is fastened on travelling carriage in chute, and be movably installed in the elastomeric check mechanism of travelling carriage bottom.In the process of utilizing elastomeric check mechanism to detect in flatness, can not cause the movement of support, can learn the situation of Slope leveling degree according to the displacement variable of elastomeric check mechanism, be conducive to carrying out smoothly of measuring process.
As the restriction to aforesaid way, described travelling carriage comprises that slip is fastened on the side plate on chute, be connected in the base plate of side plate bottom, and be positioned at the clamping plate of base plate top, described side plate slides and is arranged in chute via the dop thereon of being connected, and described elastomeric check mechanism is movably installed on base plate and clamping plate.
As the restriction to aforesaid way, described elastomeric check mechanism comprises that slip is arranged in the test rod on base plate and clamping plate, be connected in the erecting frame of test rod bottom, and rotation is arranged at the roller on erecting frame, described test rod is suspended in clamping plate and base plate via the back-up ring being connected at an upper portion thereof, is also provided with the spring being movably set on test rod between erecting frame and base plate.Roller can make elastomeric check mechanism contact for rolling with side slope surface, has reduced the sliding resistance of travelling carriage; Spring is used for making roller to keep good contact with side slope surface all the time, and in the process of sliding in slip clamp, the flatness situation on side slope surface can be reflected by the slip variable quantity of the relative clamping plate of test rod.
As the restriction to aforesaid way, on described test rod, be provided with scale mark.Scale mark is set on test rod can carry out quantitatively the slippage of the relative clamping plate of test rod, and the flatness situation of the side slope that also can react it thus quantitatively detects.
In sum, adopt the technical solution of the utility model, can realize the measurement to roadbed grade of side slope, the measuring error that can avoid common grade rod to come because of Slope leveling degree difference band in use, has good practicality.
