The invention discloses an instrument for measuring the relationship between compression and infiltration of garbage soil. At present, there is no instrument for studying the relationship between compression and infiltration of garbage soil in landfill. In the present invention, one side of the osmotic column is connected with a plurality of water outlet joints, and the other side is connected with a plurality of pressure measuring tubes arranged equidistantly; the adjustable bottom plate is connected with the water level adjustment rod through pins; Connected; the water storage tank is connected with multiple water outlet joints; the gland and the upper beam are connected by suspension rods; the lower beam, the first counterweight, and the second counterweight are all hinged with the lever; the hub and worm of the turbine are supported by bearings In the support, the worm gear meshes with the worm; one end of the worm sticks out of the support and is fixed with the hand wheel; the worm gear is connected with the screw; the bottom of the screw is hinged with the lever. The invention can realize the mechanized laboratory measurement of the permeability and compression properties of the garbage soil, and fills the vacancy of existing instruments in the research on the compression and penetration of the garbage soil.
Description
technical field [0001] The invention belongs to the technical field of experimental instruments, and relates to a geotechnical compression experiment device and a geotechnical infiltration experiment device, in particular to a measuring instrument for the relationship between compression and infiltration of garbage soil. Background technique [0002] With the continuous development of urbanization in our country, the load of urban population is increasing, which leads to the continuous increase of urban domestic waste, and the disposal of waste has reached the point of no delay. For the treatment of municipal solid waste, there are mainly the following methods at home and abroad: landfill, incineration, biodegradation, etc. Among them, landfill technology has unique advantages in the current urban development. The landfill method for treating municipal solid waste has large landfill capacity and low economic consumption, so the landfill method for treating municipal solid w...
