The invention discloses a test device for preparing an ultra-soft soil sample, which comprises a vacuum stirring device, a consolidation drainage device and a drainage monitoring device. The vacuum stirring device is connected with the consolidation drainage device through a sliding plate, the top of the vacuum stirring device is connected with an air extractor through an air extraction pipe, andthe consolidation drainage device is connected with the drainage monitoring device through a drainage pipe. The test device can be used for preparing an ultra-soft soil sample which can fully reflectthe properties of a soil body, is uniform in texture and has repeatability and of which the water content can be accurately controlled, is used for related test researches, and effectively saves the field sampling cost. 本发明公开了一种制备超软土样的试验装置，包括真空搅拌装置、固结排水装置和排水监测装置，所述真空搅拌装置与固结排水装置通过滑板连接，所述真空搅拌装置顶部通过抽气管与抽气装置连接，固结排水装置通过排水管与排水监测装置连接。该试验装置可以制备出能够充分反映土体性质、质地均匀、试样具有可重复性、且样本含水量可以准确控制的超软土样，用于相关试验研究，且有效地节省了现场取样成本。
