Soil osmotic coefficient in-situ testing device and testing method thereof
The invention relates to the technical field of measurement, in particular to a soil osmotic coefficient in-situ testing device and testing method thereof. The testing device comprises a testing barrel and a driving control box, the surface of the testing barrel is provided with a water inlet hole, a water pump and a water pressure sensor are arranged in the testing barrel, a lifting mechanism is arranged in the driving control box, a traction line of the lifting mechanism is connected with the testing barrel fixedly, the driving control box controls the testing barrel up and down by the lifting mechanism, and the traction line comprises a water guide pipe, a sensing line and a bearing line. The sensing line is connected with the water pressure sensor, the water guide pipe is connected with the water pump, and the bearing line is fixedly connected with the testing barrel. The soil osmotic coefficient in-situ testing device has the advantages that the testing device can be used fittingly in any manholes in situ and can measure soil osmotic coefficient of assigned depth.
