A pressurized micro water test device

Abstract

The utility model relates to the field of geological survey, concretely is a kind of press-in pressurized micro water test device. The device includes static pressure pipe, rigid water-permeable structure, press pipe sealing cover, water level meter, acquisition instrument and air pressure booster. Static pressure pipe bottom is connected with water-permeable structure and is pressed into target aquifer under the action of static pressure pipe equipment;Press pipe sealing cover is equipped with pressure gauge, pressure relief valve, sealing ring and pressurizing gas port;Water level meter extends into pipe and is connected with acquisition instrument, for collecting water level and pressure signal;Air pressure booster is connected with pressurizing gas port to stimulate water level. The device can complete micro water test without well completion, compact structure, easy operation, reduce construction cost and cycle, reduce disturbance to groundwater environment;Through air pressure instantaneous pressurization and pressure relief, improve test sensitivity and data accuracy;And can be selected static sounding probe collection specific resistance, realize the synchronous acquisition of hydrological parameter and formation information, have strong adaptability, test efficient and the like advantages.
