Tool for rapidly measuring void ratio of soil body and use method

The invention relates to the technical field of soil void ratio measurement, and discloses a tool for rapidly measuring the soil void ratio, which comprises a T-shaped frame, a triangular frame and a soil sampling cup, the T-shaped frame comprises a transverse rod and a threaded vertical rod, and the middle of the transverse rod is connected to the upper end of the threaded vertical rod; the lower end of the threaded vertical rod is connected with a pressurizing end; the triangular frame comprises a support, a sleeve is connected to the support, and the inner bottom face of the support is connected with a pressure bearing platform. The soil sampling cup is placed on the pressure bearing platform; the threaded vertical rod is connected to the sleeve in a screwed mode. The device has the outstanding advantages of being simple in structure, light, portable, convenient to calculate and the like, soil disturbance and complicated tests and calculation are reduced, and the void ratio of the soil can be obtained in r
