Earth throwing and filling device for centrifuge

Abstract

The invention discloses an earth throwing and filling device for a centrifuge, comprising a storing device, a throwing device and a supporting device. The storing device is arranged on a rotating arm in the centrifuge; the throwing device is arranged above the supporting device; the throwing device and the supporting device are arranged on a model box and placed in a suspended basket; and the centrifugal field of the suspended basket is larger than that of the rotating arm. Due to the arrangement of a high-capacity storing box and a small-capacity throwing box, the earth throwing and filling device can throw and fill earth in moving way. The double-box structure has good stability and high strength in the large-G-value gravitational field environment, can not lead to the overload of a moving mechanism and adopts the hydraulic driving form to feed, position and throw earth. The earth throwing and filling device can realize the layered throwing and filling of 0-400kg of cohesiveless earth under the 0-100g centrifugal field.

Description

technical field [0001] The invention relates to a centrifuge earth material throwing and filling device, in particular to a centrifuge earth material throwing and filling device capable of realizing mobile throwing and filling, layered throwing and filling of earth materials and dynamic forming. Background technique [0002] In order to study the deformation and stability of earth dams and embankments, the geotechnical centrifuge model test has become a feasible method, and various special equipment applied to geotechnical centrifuges have also emerged as the times require. The centrifuge soil material throwing equipment is a set of test equipment that can work under the centrifugal field. When the centrifuge is running, the non-cohesive soil material can be controlled and thrown into the model box through this equipment to form different sections and thicknesses. Provide the experimenter with a dynamic model forming method. [0003] At present, there are mainly two types o...

AI Technical Summary

Problems solved by technology

The mobile throwing and filling device has a good effect of throwing and filling the section, and can realize layered and dynamic throwing and filling; but due to the strength and stability of the mobile device under the large G value gravity field, the material box and pre-loaded soil materials should not be too heavy. After the second soil throwing and filling, it needs to be shut down to pre-load the soil
