Device for testing consolidation and permeation of soil under action of coupling of chemistry and stress

Abstract

The invention belongs to testing equipment in the field of geotechnical engineering, and particularly relates to a device for testing consolidation and permeation of soil under the action of coupling of chemistry and stress. A pressurizing frame (3) is arranged on the left side of the top of a table plate (4); the lower end of the pressurizing frame (3) is connected with a lever penetrating sleeve (3-1); a lever support (4-1) is fixed under the left end of the table plate (4); a lever (5) penetrates through the lever support (4-1) and the lever penetrating sleeve (3-1); a balance weight (8) is arranged at the left end of the lever (5); a weight tray (6) is arranged below the right end of the lever (5); a weight (7) is arranged on the weight tray (6); a permeation and consolidation container base (9) with a groove is arranged in the pressurizing frame (3) on the table plate (4); an exhaust hole (9-4) and a water draining hole (9-6) are formed in a pressurizing piston (9-5); the pressurizing piston (9-5) is provided with an arc-shaped pressing block positioning groove (9-11); and the arc-shaped pressing block positioning groove (9-11) is connected with a pressing block (17). The device is simple in structure and convenient to operate, and has excellent corrosion resistance and tightness.

Description

technical field [0001] The invention belongs to test equipment in the field of geotechnical engineering, in particular to a test device for consolidation and penetration of soil under chemical-stress coupling action. Background technique [0002] At present, the ordinary portable single-lever consolidation instrument used in the field of geotechnical engineering can only be used for conventional soil consolidation tests, and cannot be used for penetration tests, and for some soils whose mechanical properties are affected by chemical factors, such as tail For ore sand, the corrosion of the test device by the chemical solution cannot be avoided with a common consolidation instrument; in addition, it is difficult to meet the sealing performance requirements of the test device, which will make it difficult to maintain the accuracy of the soil consolidation and penetration test data. Contents of the invention [0003] The object of the present invention is to overcome the above...
