| titleOfInvention | Device and method for preparing undisturbed soft clay sample by low-position vacuum preloading and prepressing |
| abstract | The invention relates to a device and a method for preparing an undisturbed soft clay sample by low-position vacuum preloading combined prepressing, wherein the device comprises a model box system and a vacuum pump system; the model box system comprises a model box and a stack of support plates, wherein a sealing top cover is arranged at the top of the model box and used for sealing the model box, and an air suction hole is formed in the side wall of the model box, which is away from the bottom in the model box by a certain distance; a cross-shaped vacuum filter pipe is arranged at the bottom of the model box; the inner wall of the model box is closely attached with a plurality of plastic drainage belts; any end part of the vacuum filter tube is communicated with the air suction hole, and other end parts are tightly attached to the bottom of the plastic drainage belt; the vacuum pump system comprises a water ring vacuum pump with a water-vapor separation box; the water-ring vacuum pump is communicated with an air exhaust hole on the model box through an air exhaust pipe. The method comprises the steps of injecting slurry into a model box, draining under the action of dead weight for consolidation, and then carrying out vacuum consolidation to obtain an original soft clay sample. The method of the invention can ensure the uniformity of the water content, density and strength of the prepared sample. |
