Automatic material spreading device for similar material simulation test, and use method of automatic material spreading device

Abstract

The invention discloses an automatic material spreading device for a similar material simulation test, and a use method of the automatic material spreading device. The automatic material spreading device integrates a material accommodating box and a vibration device; a vibrating motor is used as a vibration source for realizing material spreading and tamping vibration; an auxiliary extrusion for force application is carried out through a hydraulic cylinder according to conditions to ensure that requirements on the flatness and the consistence of a simulation rock formation can be met in a similar material model production process. Compared with the prior art, the automatic material spreading device is simple in structure, flexible in control, high in maneuverability and production efficiency, low in labor intensity, excellent in material spreading and tamping effect, and the like; the forming speed and quality of the similar material model can be greatly improved, and the consistency of the similarity ratio of thickness to strength of the formed simulation rock formation is greatly improved; in addition, the automatic material spreading device has the benefits of being low in manufacturing cost, convenient to assemble and disassemble, low in maintenance and repair cost, and the like.

Description

technical field [0001] The invention relates to a similar material simulation test device and its use method, in particular to an automatic material laying device for similar material simulation test and its use method. Background technique [0002] The similar material simulation test can comprehensively consider the structure and rock mass characteristics of underground engineering, qualitatively reflect the deformation and failure characteristics of on-site engineering rock mass, cooperate with field observation and theoretical research, and guide engineering design and construction reasonably. It is widely used in mining, Geotechnical, water conservancy, railway and other fields. [0003] At present, similar simulation experiments mainly rely on manual completion in the process of model making. For modeling with relatively small body sizes, the disadvantages of this method are not very obvious. However, for "large" similar material models, such as models with a length ...

Problems solved by technology

However, the structure of this type of device is complex and the manufacturing cost is relatively high. During the working process, all parts of the device vibrate together with the vibrating plate, resulting in a high failure rate of the equipment and high maintenance and repair costs; The actual need to adjust the vibration force between layers, the consistency of the compactness and similarity ratio of the simulated rock layer after forming cannot be guaranteed
