Abstract

The invention provides an in-situ intelligent permeability coefficient measuring device used in cooperation with a water suction pump. The in-situ intelligent permeability coefficient measuring deviceis provided with an automatic pay-off device, a connecting cable and a probe measuring device. The probe measuring device is provided with an upper pressure sensor, a lower pressure sensor and a stainless steel sleeve. The upper pressure sensor and the lower pressure sensor are fixedly installed on the inner wall of the top and the inner wall of the bottom of the stainless steel sleeve respectively, a cable penetrating hole is formed in the center of the upper pressure sensor, and the front portion of the connecting cable is electrically connected with the upper pressure sensor and the lowerpressure sensor in the stainless steel sleeve through the cable penetrating hole. A sealing body is arranged at the connecting cable and the cable penetrating hole. The device is continuous in test result, high in measurement speed, low in cost, simple in structure, convenient to operate, convenient to carry, free of special water pumping (injecting) equipment, simplified in measurement process and high in measurement precision, and the problems that water level measurement steps are tedious and time-consuming in the on-site in-situ water pumping test and manual timing measurement is needed are effectively solved.
