Abstract

The invention discloses an air-inflation rapid demolding device and a mold, and relates to demolding in a geotechnical laboratory. The air-inflation rapid demolding device comprises a telescopic device, a mold placement table and a material receiving table, wherein the telescopic device, the mold placement table and the material receiving table are arranged in grooves in an operation table in parallel; a levelling lifting mechanism capable of adjusting a height is arranged at the bottom of the operation table; and during demolding, mold samples are placed in a mold placement plate, the telescopic device sequentially carries out air inflation on the mold and a push rod, and after the opening of an annular wall of the mold is expanded to reach the maximum diameter, the push rod drives a pushplate to push the samples in the mold to move to the material receiving table. The air-inflation rapid demolding device is capable of increasing the demolding efficiency, and demolding a plurality ofthe samples in one process; and starting and shutdown of the demolding device can be intelligently controlled, so that the integrity of the samples can be ensured while the labor is greatly saved.

Description

technical field [0001] The invention relates to an inflatable rapid demoulding device and a mould, in particular to an inflatable rapid demoulding device and a mould, which are suitable for testing soil mechanical properties in the discipline of civil engineering. Background technique [0002] With the acceleration of urbanization, more and more buildings are built on coastal soft soil foundations. The test of the mechanical properties of soft soil has become an important content in the civil engineering discipline. The triaxial test is a common experimental method for measuring the mechanical properties of soft soil. The sample is a cylinder with a diameter of 3.91 cm and a height of 8.0 cm. Due to the large error of the geotechnical test, a large number of samples are required for each group of tests to obtain data to reduce the error value. Laboratories usually use manual demoulding. Due to the large number of experimental samples, the efficiency of manual demoulding is...
