Abstract

The invention discloses a tester for researching a compression-permeation relationship of garbage soil, which aims at filling up the blank of an instrument for researching a compression-permeation relationship of garbage soil in landfill at present. According to the tester, one side of a permeation column is connected with a plurality of water outlet joints and the other side of the permeation column is connected with a plurality of piezometric tubes which are arranged equidistantly; an adjustable bottom plate is connected with a water level adjusting rod through pins; a water storage tank is communicated with the permeation column through a water inlet pipe and is connected with a plurality of water outlet joints; a gland is connected with an upper crossbeam through a suspension rod; a lower crossbeam, a first balancing weight and a second balancing weight are hinged with a lever; both a hub of a worm wheel and a worm are borne in a support through bearings; the worm wheel is meshed with the worm; one end of the worm extends out of the support to be fixed with a hand wheel; the worm wheel is connected with a screw rod; the bottom of the screw rod is hinged with the lever. According to the tester, the mechanical laboratory measurement on the permeation property and the compression property of garbage soil can be performed and the research gap of the compression and permeation of garbage soil from existing instruments is filled.

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...
