Description

Technical Field

[0001] The present invention relates to the technical field of sample assembly equipment, and in particular to a unidirectional large-size sample assembly equipment and a method for using the unidirectional large-size sample assembly equipment. Background Art

[0002] Size effect is common in rock and soil mechanics. In order to better understand the impact of size effect on mechanical properties, it is necessary to test samples in a large size range, and the samples need to be assembled before testing. For ultra-long samples, it is very difficult to assemble according to certain requirements, because there are often cracks inside ultra-long rock and soil samples, and the bending moment and torque during the installation process may cause the sample to break. The use of overhead cranes is difficult to meet the requirements and there are greater safety risks. Some existing equipment for installing products generally does not have the situation where the product is too long and fragile, such as patents 201721172311.1, 201920813477.X, 201310201247.5, etc. Patent 202011430711.4 discloses a multi-scale specimen lifting and flipping device with continuously stepless adjustable width, and provides a specimen assembly device with a large length. It is effective for loading and installing hard rock samples, but for specimens with internal cracks or prefabricated cracks, grabbing at both ends will cause the middle of the specimen to break, which is related to the torque generated by the synchronization deviation of the flipping specimen and the influence of the gravity of the specimen itself. Offsetting the flipping torque and supporting the specimen at multiple locations along the length direction can ensure the safety of the specimen and the operator, and the convenience of transporting the specimen before and after assembly is also an important consideration. Therefore, it is very meaningful to develop a unidirectional large-scale geotechnical specimen assembly device for internal defects to study the size effect. Summary of the invention
