The utility model discloses a quantitative geotechnique's utensil of drawing, including the handle, the one end of handle is fixed on the soil storage ware, mainly is the square sword that is used for cutting soil reduced drag at another of soil storage ware, and the another side nestification of handle is on horizontal bracket, and the slip that can make a round trip on horizontal bracket of handle, and horizontal bracket is used for guaranteeing drawing that the soil storage ware of soil is perpendicular moves with the level, the utility model discloses a ration is realized to capacity through the soil storage ware. The utility model relates to a simulation experiment experiments tool of the subsidence area soil crack development that research coal mining arouses. To current simulation experiment instrument, be not applied to the instrument of testing argil specially, experimental efficiency is low, draws the inaccurate scheduling problem of control of soil volume. The utility model discloses fine solution the control problem to drawing the soil volume, improved experimental efficiency, just the utility model discloses simple structure, low in cost, the suitable popularization.
