Problems solved by technology

At present, due to the limitation of technical means, the traditional slope geological model test device can only repeatedly compact the soil with heavy objects from top to bottom, so as to achieve the effect of compacting the soil and make it reach a certain degree of compactness. The method is not only time-consuming and labor-intensive, but also the compaction of the soil is uneven due to the limitation of the compaction range, and it is difficult to control the compaction strength due to the multi-layered soil, which will cause the results of the model test to be different from the real situation. Inconsistency affects the accuracy of test results

Abstract

The invention provides a hand-operated geologic model test soil body layering grinding device which comprises a model frame, a pressing wheel and a traction mechanism. A first baffle and a second baffle are installed on the two opposite side faces of the model frame, the circle centers of the two side faces of the pressing wheel are each provided with a first transmission bearing, the pressing wheel is located inside the model frame and is close to the first baffle, the traction mechanism is located on the outer side of the second baffle, the traction mechanism comprises a crank-shaped rotating rod and two fixing screws, one ends of the two fixing screws are detachably fixed to the second baffle, the other ends of the fixing screws are connected with second transmission bearings, the rotating rod penetrates through the two second transmission bearings and can rotate, two winding rings and two parallel elastic ropes are installed on the rotating rod, the elastic ropes penetrate throughthe second baffle, one ends of the elastic ropes are fixed to the winding rings, and the other ends of the elastic ropes are fixed to the first transmission bearings. The device has the advantages that the pressing wheel can evenly grind a soil body, the pressing wheel grinding frequency is controlled, the different soil layer compactness requirements are met, and the soil body true condition is accurately restored.

Description

technical field [0001] The invention relates to the field of geological disaster model tests, in particular to a hand-operated soil layered rolling device for geological model tests. Background technique [0002] Due to the frequent occurrence of slope geological disasters and the wide range involved, it has brought great changes to the slope investigation work. Therefore, the slope geological model test is more and more used in the field of slope analysis. . At present, due to the limitation of technical means, the traditional slope geological model test device can only repeatedly compact the soil with heavy objects from top to bottom, so as to achieve the effect of compacting the soil and make it reach a certain degree of compactness. The method is not only time-consuming and labor-intensive, but also the compaction of the soil is uneven due to the limitation of the compaction range, and it is difficult to control the compaction strength due to the multi-layered soil, whi...
