Abstract

The invention belongs to the field of soft and hard interbedding rock mass testing, and relates to a soft and hard interbedding rock test sample manufacturing device, comprising: a pre-pressing die, acutting and stacking unit and a pressing die. The invention further relates to a soft and hard interbedding rock test sample manufacturing method, utilizing the above method and comprising the following steps: preparing a soft layer mixed material; preparing a hard layer mixed material; preparing a soft layer material block and a hard layer material block; preparing a soft and hard interbedding material block; preparing a soft and hard interbedding compression block; and preparing a soft and hard interbedding rock test sample. By adjusting the distance between a load bearing plate and a material stacking port, the interbedding thickness of a soft and hard interbedding material can be conveniently controlled, the inclination angle of the soft and hard interbedding compression block with the horizontal plane is fixed after being solidified, a sample is extracted by using a core drilling machine, and the interbedding inclination angle can be controlled; and the manufacturing process is simple, the manufacturing efficiency is high, meanwhile, a single-layer material is carried and stacked in the manufacturing to ensure the integrity of a single-layer sample.

Description

technical field [0001] The invention belongs to the field of soft-hard interbedded rock mass testing, and relates to a production device and method for soft-hard interbedded rock samples. Background technique [0002] Soft-hard interbedded rock mass refers to a rock mass composed of two or more groups of rock masses with large differences in strength forming an interlayer structure. Due to the large difference in lithology between soft rock and hard rock, soft rock will develop into Weak interlayers that seriously affect the stability of surrounding rocks cause a large number of disasters to occur from time to time under the action of external geological stress, resulting in serious economic losses. Soft and hard interbedded rock mass is a kind of rock mass often encountered in the process of tunnel construction. With the continuous development of tunnel engineering, it is inevitable to pass through areas where soft and hard rock interbedded surrounding rocks such as red bed...
