Portable multifunctional rock-soil body seepage experiment table

Abstract

The invention relates to a portable multifunctional rock-soil body seepage experiment table which mainly comprises an experiment table body, a water supply system and an experiment data measuring device, wherein multiple rows of water inlet and outlet seepage channels which are parallel to each other are arranged on the experiment table base of the experiment table body and are intersected and communicated in the middle of the experiment table base; prefabricated crack blocks are arranged in the water inlet and outlet seepage channels; water pipes forming circulation paths with a water pump are respectively arranged at the water joints of the two sides of each of the flowing water seepage channels; and a pressure sensor, a liquid filter valve, a flow sensor and a control valve are respectively arranged on each of the water pipes at the two sides of each of the flowing water seepage channels in turn. The migration condition of fluid and grains in the fluid in an experiment can be observed in real time; the change of infiltration capacity of a crack or pore medium under a vibrating condition can be measured in real time by placing the experiment table on a vibrating platform; and the portable multifunctional rock-soil body seepage experiment table has the advantages of simple structure, small size and good experiment effect, is portable, is convenient to operate and can be placed at random.

Description

technical field [0001] The invention relates to a seepage test bench, in particular to a portable and visualized multifunctional seepage test bench suitable for simulating seepage in fissures or porous media in rock and soil, underground engineering, water conservancy and hydropower projects. Background technique [0002] The seepage of fractured or porous rock and soil has an important impact on the safety of geotechnical engineering and underground engineering. Now many scholars have done a lot of theoretical and experimental research on it. In practice, cracks in rock and soil often intersect to form a network of cracks. At present, few scholars have conducted experiments to verify the flow of fluid in intersecting cracks in rock and soil; moreover, cracks and pores often coexist in rock and soil, although many Scholars have conducted research on the seepage of rock and soil where cracks and pores coexist, but few people have carried out experimental verification; in add...

In practice, cracks in rock and soil often intersect to form a network of cracks. At present, few scholars have conducted experiments to verify the flow of fluid in intersecting cracks in rock and soil; moreover, cracks and pores often coexist in rock and soil, although many Scholars have conducted research on the seepage of rock and soil where cracks and pores coexist, but few people have carried out experimental verification; in addition, the experimental research on the mechanism of sediment transport in rock and soil cracks and the mechanism of sediment transport under vibration conditions has not yet been carried out. rarely reported
