Abstract

The invention discloses an under-consolidated remolded soft clay sample preparation device. Round clamping grooves for clamping an outer mold and an inner mold are formed in a base and a top cover; the outer mold and the inner mold are connected in a sleeving manner and are clamped into the round clamping grooves of the base and the top cover respectively; at least three through holes are formed in the top cover around the outer mold; thread connecting holes, corresponding to the through holes, are formed in the base; screw rods penetrate through the through holes and are in thread connectionwith the thread connecting holes, and the outer mold and the inner mold are fastened; loading holes are formed in parts, aligned to the inner mold and the outer mold, on the top cover; at least threesupporting rods, which are matched with annular loading grooves, are arranged at the lower part of a loading bracket; the supporting rods are inserted into the annular loading grooves; a load plate isarranged at the upper ends of the supporting rods; annular water discharging plates are lined at the upper and lower ends of an annular soil sample between the outer mold and the inner mold; the water discharging plates are provided with water discharging through holes; a water discharging hole channel is arranged on the base. The under-consolidated remolded soft clay sample preparation device disclosed by the invention can be used for effectively simulating a one-dimensional compression and consolidation state of under-consolidated soil in a deposition process.

Description

technical field [0001] The invention relates to a one-dimensional under-consolidated remodeling soft clay sample preparation device for testing, which belongs to the technical field of geotechnical engineering measuring instrument manufacturing and is suitable for making soft clay samples of under-consolidated hollow cylinders and placing them in hollow cylinders Experimental studies of soils were carried out in a torsional shear system. Background technique [0002] Geotechnical testing in the field of geotechnical engineering is the main means to obtain soil physical and mechanical parameters. In soil testing, according to the national standard of the People's Republic of China "Standards for Soil Testing Methods" (GB / T 50123-1999), it is first necessary to adopt scientific, standardized and effective methods to obtain and prepare soil samples. This is also an important guarantee for the high reliability of various physical and mechanical parameters of the soil obtained i...
