Abstract

The invention belongs to the technical field of soil test research, and particularly relates to a consolidation and penetration measuring device. The measuring device can carry out a consolidation test and a penetration test at the same time. The consolidation and penetration measuring device enables test operation to be simple and convenient and enables test results to be accurate. The consolidation and penetration measuring device comprises a pressurization cylinder, and is characterized in that a pressurization piston is arranged in the pressurization cylinder; the pressurization piston can move upwards and downwards in an inner cavity of the pressurization cylinder, and gaps are reserved between the pressurization piston and a cylinder wall of the pressurization cylinder; and a water inlet is formed in a base of the pressurization cylinder, and a water overflow port is formed in the cylinder wall on the upper portion of the pressurization cylinder.

Description

technical field [0001] The invention belongs to the technical field of geotechnical test research, and in particular relates to a consolidation penetration test device, which can simultaneously perform a consolidation test and a penetration test. Background technique [0002] In the field of geotechnical test research, in many cases, it is necessary to measure the relationship between soil permeability coefficient and void ratio or unit settlement. The main instrument for soil sample consolidation test in the prior art is the consolidation instrument in the "consolidation test" described in "Standards for Soil Engineering Test Methods" (GB / T50123-1999), and the main instrument for soil sample penetration test It is the constant head permeameter in the "Constant Head Penetrability Test" described in the "Standards for Soil Test Methods" (GB / T50123-1999) and the "variable test" described in the "Standards for Soil Test Methods" (GB / T50123-1999). The variable head osmometer in...
