Abstract

The invention relates to an additive manufacturing device and method for ultralow-temperature solidified supersaturated soil, the additive manufacturing device is composed of a base, a double-x-axis sliding rail, a y-axis sliding rail, a z-axis sliding rail, a liquid nitrogen bin, an air pressure controller, a slurry extruder, a test piece mold and a sliding rail controller, the air pressure controller is provided with a master control valve, and the flow speed and start and stop of the extruder can be controlled; the test piece mold is provided with a liquid nitrogen tank and an aluminum alloy mold shell, and the liquid nitrogen conveying pipe conveys liquid nitrogen into the liquid nitrogen tank, so that the aluminum alloy mold shell is rapidly cooled to an ultralow temperature and enters a working state. By utilizing the device, test pieces with various sizes can be customized according to set requirements, and the device has the characteristics of high precision, wide customizable range and the like.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to a device and method for ultra-low temperature solidified supersaturated soil additive manufacturing. Background technique [0002] The strength of soil is mainly controlled by temperature and water content, and these two factors affect each other, and the influence of temperature on strength is expressed through water content (ice content). The change of moisture content will lead to substantial changes in strength and volumetric deformation of soil after freezing in negative temperature environment. When the soil is in a supersaturated state, the strength at low temperature will be dominated by ice, which is quite different from the mechanical characteristics of traditional soil at low temperature. Various static and dynamic indexes of saturated soil have very important reference value. [0003] However, supersaturated soil will face quite difficult technical problems in ...
