Multi-head soil three-axis rheological testing machine

The utility model relates to a multi-head soil three-axis rheological testing machine, belonging to the field of testing instruments. Three axial loading systems are arranged in parallel and are fixedly connected with the lower surface of a bedplate of a frame; three enclosed pressure chambers are fixedly connected with the upper surface of the bedplate of the frame respectively; three enclosed pressure loading systems are fixedly connected with a base plate of the frame; three electronic balances used for measuring pore water flow rate are respectively and fixedly connected with a bearing plate below the bedplate of the frame; a pressure transmitter used for measuring the enclosed pressure and a pressure transmitter used for measuring the pore water pressure are fixedly connected with the base; and a grating sensor used for measuring the axial deformation of the sample is fixed on the bracket of the base of the enclosed pressure chamber. The multi-head soil three-axis rheological testing machine has the following advantages: the structure is novel; three enclosed pressure chambers, three axial loading systems and three enclosed pressure loading systems are arranged on one frame so as to test three samples at one time, the testing efficiency is improved greatly; and the use is convenient and flexible and the long-time operation is reliable.
