Laying device and using method of similar simulation experiment material

Abstract

The invention discloses a paving device for an analogue simulation experiment material and a use method of the paving device. The paving device comprises an analogue simulation experiment bench as well as a hydraulic pushing jack, a guiding crossbeam, an extrusion crossbeam, two parallel guiding rails, a fixed beam and a cover plate which are arranged in the analogue simulation experiment bench, wherein the hydraulic pushing jack is located above the guiding rails, the cover plate is located below the guiding rails, and the guiding rails are used for the cover plate and the guiding crossbeam to move; and the guiding crossbeam and the extrusion crossbeam are fixedly connected, the fixed beam and the guiding crossbeam are correspondingly arranged in parallel and are respectively connected totwo ends of the hydraulic pushing jack, connecting holes are respectively formed in two ends of the connecting beams, and two ends of the fixed beam are respectively fixedly connected with the two guiding rails through the connecting holes. According to the paving device, the problems that the strength and thickness of a rock layer paved at the lower part are influenced by traditional vertical knocking and vibration are solved; and by arranging the new paving device, a paved local rock body and a paved lower rock layer are not influenced in the paving process.

Description

technical field [0001] The invention relates to the field of coal, in particular to a laying device and a use method of similar simulation experiment materials. Background technique [0002] The similar material simulation test is based on the site engineering geological conditions, and uses similarity theory, dimensional analysis and other methods to simulate and reproduce the engineering site in the laboratory. It is widely used in engineering technology fields such as mining engineering and geotechnical engineering. The similarity between the laboratory similar material and the engineering site rock mass material in terms of geometric size, density, strength, etc. directly determines the success or failure of the similar simulation test. [0003] At present, the laying and compaction of materials for similar simulation tests are mainly done manually or by vibrating machines. For example, Shandong University of Science and Technology proposed an automatic material laying d...
