Description
Technical Field
The utility model relates to a compressive strength sample sampling equipment especially relates to a mud does not have confined compressive strength sample sampling device.
Background
Unconfined compressive strength refers to the ultimate strength of a test specimen against axial pressure under conditions of no lateral pressure. In the triaxial test, axial pressure is applied to a cylindrical sample without applying any lateral pressure until the sample fails in shear. And the axial pressure when the sample is damaged is the unconfined compressive strength.
Sludge is a product after sewage treatment, and is an extremely complex heterogeneous body consisting of organic debris, bacterial cells, inorganic particles, colloids and the like. The sludge has high organic matter content, is easy to decay and stink, has fine particles and smaller specific gravity, and is in a colloidal liquid state. Municipal sludge comes from municipal domestic sludge treatment plants, the water content of the municipal sludge is 60-80%, the treatment modes comprise various modes such as good composting, anaerobic digestion, dehydration, drying, incineration and the like, and the refuse landfill is the final treatment site for most of the sludge.
