Abstract

The invention discloses an electromagnetically controlled soil sample compactor, comprising a mechanical part and an electric control part. The electromagnetically controlled soil sample compactor is characterized in that the mechanical part includes a frame (2) provided with an upright column on the two sides, a base plate (9) and a beam; each of the two sides of the frame (2) is fixed with a pneumatic cylinder (5) with an electromagnetic reversing valve (11); a U-shaped lifting frame (4) is fixed on the pneumatic cylinders (5) and is vertically provided with a through hole in which a guide rod (3) is formed; a buffer plate (23) is fixed at the bottom of the guide rod (3); an electromagnet component (6) is fixed in the middle of the bottom of the U-shaped lifting frame (4); and an impacting block (7) is mounted on the guide rod (3). The electromagnetic component (6) is electrified to attract the impacting block (7), and meanwhile, the pneumatic cylinder (5) drives the impacting block to ascend to reach the preset height, then the magnet is disconnected, the impacting block (7) falls to impact the buffer plate (23) to complete once compaction for the soil sample in a soil box (10), and continuous impaction and compaction is implemented by repeating the procedure.

Description

technical field [0001] The invention relates to a geotechnical material testing instrument and equipment, in particular to an electromagnetically controlled soil sample compacting device, referred to as a soil sample compacting device. Background technique [0002] The main diseases of the subgrade include subsidence of the subgrade, slope slide, slope collapse and fragmentation, embankment sliding along the hillside, embankment collapse, and subgrade damage caused by unfavorable geological and hydrological conditions, etc. Practice has proved that increasing the degree of compaction is an important measure to solve roadbed diseases, especially uneven settlement diseases. economic contradiction. [0003] To solve these problems, engineers around the world are pursuing various measures. As a result, the application of geosynthetics in roadbeds (especially embankments, soft foundations, retaining walls and dams that require high fill) has emerged, because it can increase the...
