The intelligent permeability coefficient tester comprises a protective shell, a water storage tank is connected to the bottom end of the interior of the protective shell, a water seepage test box is arranged on one side of the top of the water storage tank, and a water seepage test material layer is arranged in the middle of the interior of the water seepage test box; the water seepage test box is divided into a constant water pressure height measuring cavity and a water seepage cavity by the water seepage test material layer, the liquid level height in the constant water pressure height measuring cavity is sensed by the liquid level of the sensor, so that the control screen controls the stepping motor to rotate, the stepping motor rotates to drive the coupler to rotate, and the coupler rotates to drive the rotating blade to rotate; and water in the flow control water valve is conveyed. And the conveyed water is equally divided by the water distributor after passing through the rotary water pipe, so that the measured flow flowing out of the single pipe is the permeability coefficient. The tester has the characteristics of full-automatic operation, small measurement error, high precision and the like.
Description
technical field [0001] The invention relates to the technical field of coefficient testing, in particular to an intelligent permeability coefficient tester. Background technique [0002] The permeability coefficient is an empirical coefficient in the calculation formula of the penetration rate of porous media, and it is also a parameter representing the water permeability of soil or rock with crevices. The general seepage process obeys Darcy's law, that is, the seepage velocity is linearly related to the hydraulic gradient of seepage, and the ratio k is the permeability coefficient, measured in m / (24 hours) or cm / s. [0003] The existing permeability coefficient testing methods all have certain defects, and there are mainly three current technical status; one is the measuring cylinder stopwatch method, which measures the permeability coefficient with a certain height of constant water pressure according to the requirements of the national standard measurement, and the device...
