Description
Technical field
The present invention relates to measure the improvement of solid material physical property surveying instrument, particularly non-granular material friction angle analyzer.
Background technology
Angle of friction is one of most important index of weighing extent of stability between material self and the two kinds of different materials.Measuring granular material friction angle in the prior art mainly finishes with direct shear apparatus.Upper and lower two shear boxs are being set on direct shear apparatus, when measuring the angle of friction of material, detected materials is packed in the shear box, measure the angle of friction of material by the mutual changing of the relative positions of upper and lower two shear boxs, by test record data, point plot, processes such as mapping and calculating could obtain angle of friction and critical grade.Current, New Building Materials continue to bring out, as: geotextile, geomembrane and benzene plate etc. use in construction work in a large number, measure the angle of friction of these non-granular materials with direct shear apparatus, especially the angle of friction of two kinds of different materials (having a kind of non-bulk solid at least) is very difficult, or does not reach required precision.
Summary of the invention
The object of the present invention is to provide a kind of non-granular material friction angle analyzer, not only it is simple and reasonable, is convenient to operation, can directly determine the angle of friction and the critical grade of non-granular material, and finding speed is fast, measures the precision height, and is easy to operate.
The object of the present invention is achieved like this: a kind of non-granular material friction angle analyzer, comprise bearing that has the leveling nut and the horizontal bubble of on the bearing table top, installing, the symmetrical support upper end that installs at the bearing table top is installed with rotating shaft, affixed upper surface has the worktable of working face in the rotating shaft that is positioned at symmetrical support, affixed the debugging bearing at the back side of worktable, the fine-tuning nut that is provided with on bottom surface and the bearing of debugging bearing matches, be positioned to be installed with on the rotating shaft one side shaft end of symmetrical support outside and screw nut, the gradient survey dish that has price fixing and Moving plate is installed on the cantilevered axle of opposite side successively, friction angular measurement dish, the bracing frame of magnifier is equipped with in nonadjustable signal and end, wherein the price fixing of gradient survey dish and support fix, the Moving plate of gradient survey dish and angle of friction mensuration dish are fixedly mounted in the rotating shaft, friction angular measurement dish is for being provided with the survey dish that has scale on survey dish seat, with rotating shaft nonadjustable signal movingly be T-shaped scale, through hole on its horizontal ruler and rotating shaft movingly, its vertical linking arm lower end is fixedly connected on the bearing.
When needs are measured non-granular material friction angle, analyzer of the present invention is placed on the more flat relatively table top, adjusting leveling nut and horizontal bubble makes the bearing table top be in horizontality, the non-granular material such as the geomembrane of needs test, geotextile or benzene plate are tiled on the working face of worktable, and another kind of non-granular material such as concrete block, mortar body piece or benzene plate are placed on it, under its weight and the actual condition on the material unit area suffered power close, transfer pine to screw nut, the hand adjustment worktable makes it be in the position that two kinds of non-granular materials are tending towards relative slip, adjust fine-tuning nut again and make its jacking debugging bearing, appropriateness adjustment screws nut, and rotary fine adjustment nut gently, make the workplace of the worktable steepening that tilts gradually, observe the tested material on range finding scale and the working face, when material slided relatively, fine-tuning nut just stopped the rotation.Because worktable and friction angular measurement dish all are fixedly mounted in the rotating shaft, when worktable rotates the inclination steepening gradually around the shaft, the also rotation thereupon of friction angular measurement dish, when the worktable steepening that tilts gradually, tested material on working face takes place to slide relatively and stops, can read the reading of nonadjustable signal on friction angular measurement dish by magnifier, this numeral is exactly the angle of friction of tested non-granular material.Because gradient survey dish price fixing and support fix, gradient survey dish Moving plate is fixedly mounted in the rotating shaft, when measuring the angle of friction of tested non-granular material, rotating shaft drives gradient survey dish Moving plate and has turned over corresponding central angle, therefore, can read indicated value on the gradient survey dish Moving plate by the index on the gradient survey dish price fixing, this reading is the non-granular material residing value of slope of surveying on worktable this moment.Analyzer of the present invention is simple and reasonable, and is easy to operate, can directly determine the angle of friction and the critical grade of non-granular material.Finding speed is fast, measured value precision height, and its circle reading precision is in 6 seconds.Do not need as direct shear apparatus test, by instrument test, record data, point plot, processes such as mapping and calculating could obtain angle of friction and critical grade.Analyzer simple testing process of the present invention, quick is a kind of more satisfactory non-granular material testing tool.
