Abstract

The invention discloses a device for producing a cylindrical test piece for a rock and soil test, aims to achieve rapid production of the cylindrical test piece for the rock and soil test through a lever compacting device and an electric heating matched mould device integrating electric heating sheets, overcomes the defects of high labor consumption, long drying time, low production efficiency andthe like during the conventional smashing hammer knocking compaction, and achieves test piece production with high efficiency and low labor consumption. The device for producing the cylindrical testpiece for the rock and soil test comprises a machine frame device, the electric heating matched mould device, the lever compacting device and a timing and temperature control device. The device for producing the cylindrical test piece for the rock and soil test is convenient to operate and easy to maintain, and has a broad application prospect in the production of rock and soil test pieces.

Description

Technical field [0001] The invention relates to a test piece preparation device, in particular to a rock and soil test cylindrical test piece preparation device. Background technique [0002] In the process of research in the field of rock and soil mechanics, it is usually necessary to conduct a large number of experimental studies on the mechanical properties of the rock. Because it is difficult to obtain the original rock specimens, the cylindrical specimens with materials similar to the rock composition and a certain proportion of water are used as the Physical model testing of mechanical properties is a widely used research method. The traditional sample preparation device relies on hammering and compaction, and needs to wait for the moisture in the sample to dry naturally, which causes the shortcomings of large manpower consumption and long waiting time, which cannot meet the needs of the tester, so it is necessary to design a Geotechnical test cylindrical specimen preparat...
