Multi-linkage full-automatic low-temperature high-pressure consolidometer

Abstract

The utility model discloses a multi-linkage full-automatic low-temperature high-pressure consolidometer which is composed of a consolidometer assembly, a refrigeration and heat preservation assembly and a temperature and pressure control and data acquisition system. The refrigeration device adopts semiconductor refrigeration, is manufactured by utilizing the Poeltier effect of a semiconductor material, does not need a refrigerant, has the characteristics of small size, light weight and the like, and is reliable in work, simple and convenient to operate and easy to adjust the cooling capacity.The refrigerating device and the heat preservation device are welded into a whole, so that the consolidometer and the whole sample are in a constant low-temperature environment. Refrigeration is not excessively concentrated, and local damage to the consolidometer is avoided. A set of temperature and pressure control and data acquisition system can be connected in series with multiple groups of consolidometers for linkage work, the structure is simple, the design is reasonable, and the practicability is strong.

Description

technical field [0001] This patent belongs to the technical field of consolidation instrument, and specifically relates to a multi-linkage automatic low-temperature and high-pressure consolidation instrument. Background technique [0002] Consolidation instrument is used to measure the compressive properties of soil under different load conditions. It can carry out normal slow consolidation test and rapid consolidation test, and measure the early consolidation pressure and consolidation coefficient. Most of the consolidation instruments are only suitable for the consolidation test of the staff at normal temperature or in the case of thawing soil. [0003] The original low-temperature consolidation instrument uses liquid nitrogen refrigeration. Due to the relatively long duration of the consolidation test, the consumption of liquid nitrogen is large, and frequent nitrogen filling increases the cost of the test. In addition, liquid nitrogen refrigeration instantly cools down,...
