Abstract
A sample preparation mould and a sample preparation method for the triaxial test of MSW are provided. In the present invention, the cylindrical main mould comprises two curved steel pieces, and the two sides of each curved steel piece have a stretched connection part; the two curved steel pieces are connected with each other and clamped by two steel clamps; porous stones are arranged at two ends of the cylindrical main mould and fixed separately by a top limiting lantern ring and a bottom lantern ring; the top limiting lantern ring is detachably connected to the top hopper, from which MSW materials are input; the cylindrical main mould is radially constrained in four positions, and the two ends thereof are axially constrained, thereby significantly improving stability during compacting and hence ensuring the axial and radial sizes of the MSW sample.
