Abstract

The invention discloses a solid garbage deformation and intensity related tester. The instrument for studying the deformation and shear intensity relationship of garbage soil in the landfill body is not provided at present. The solid garbage deformation and intensity related tester comprises an information collecting system, a deformation device, a shear device and a sample preparation device, wherein the deformation device comprises a lifting screw rod, an upper fixing platform, an upper oil pressure device and a lower fixing platform; the shear device comprises a telescopic device, a fixing column, an upper shear column, a lower shear column, a translation vehicle and a lower oil pressure device; one end of the fixing column is hinged to the oil pressure column of the telescopic device, and the other end of the fixing column is freely arranged and is provided with two hook claws; two grooves are relatively formed in the lower shear column; the information collecting system comprises an oil supply system, a control module and a data collector. The solid garbage deformation and intensity related tester has the advantages that the garbage soil under stress load is performed with deformation measuring by the oil pressure devices, and the stress state of the garbage soil at the part 100m under the landfill is simulated; the change value of the shear intensity of the garbage soil is detected under the condition of existence of stress state.

Description

Technical field [0001] The invention belongs to the technical field of experimental instruments, relates to a geotechnical deformation experiment device and a geotechnical shearing experiment device, in particular to a solid waste deformation and strength correlation measuring instrument. Background technique [0002] With the increase in the number of cities in our country, the expansion of the scale, the increase in population, the changes in people's lifestyles and the improvement of living standards, urban domestic waste has increased rapidly at an average annual growth rate of 8.98%. The huge amount of urban waste has posed an increasingly serious threat to the city and its surrounding ecological environment: the amount of domestic waste around the city has reached 6 billion tons, occupying more than 500 million square meters of land; the waste is directly stacked and simply landfilled The field releases a large amount of harmful gases into the atmosphere, which also contain...
