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...
