Single-level Light Duty Direct Shear Tester Easy to Carry for The Field Test
Single-lever light of the direct shear tester for determination of soil shear strength, angle of internal friction and cohesion. The instrument has a tracking device to ensure that the output accuracy. Easy to carry, for the field test, and could make flooding shear test.
1, Remove the instrument case and instruments four weeks plug, the instrument is placed on the platform, adjust the column screw, the instrument is stable and tight and cap
2, Hexagonal bolts on the beam a little and tight frame, so that the framework of the basic stability and leverage.
3, On both sides of the check lever and hanging ring whether phase friction, direct shear apparatus for rolling bearing should be flexible and adjust the counterweight, so that the lever weight of the basic balance and tight balance between the hammer and cap, unscrew the bolt lever fully disengaged and leverage in the column middle.
4, Cut box, check, rolling ball should be placed rolling five flexible foreign body stuck resistance, a point of order into the soil, place the permeable stone, pass the plate to make the framework pass on the pressure screw to align the ball center.
5, Shake the hand wheel on the box just touches the ring within their means, the dial indicator to zero, while the vertical displacement dial indicator to zero, spin move pass pressure screw, amount of leverage is too high, if the sample without preload slightly higher, leaving the lever is tilted too far so as not to increase the soil samples after the sinking.
6, According to project the actual need to impose the vertical load at the middle of the column (basic lever should) be soil samples by uploading or fixed, tighten the screw bolt and shake the hand wheel to be cut at an even speed, depending on the ring within their means the dial indicator pointer forward, or have back, write down the value, the general shear displacement of about 4mm. When the dial indicator readings in the direct shear apparatus for shearing process with no peak, can be cut to 6mm.
7, After the end of the shear, exit shear and vertical loads (pull out the bolt, quick spin back into the pole), recovery. Portable portable direct shear apparatus, strain direct shear apparatus, triple the consolidation of instrument maintenance and precautions:
A. the end of the experiment, the shear box to wipe clean, direct shear apparatus coated with thin layer of anti-rust oil.
B. within their ring should be based on usage or six months, a re-calibration.
C. the lever at the bearing half a year or based on usage should be given to cleaning coated with grease slide
