Abstract

The invention relates to a ground water seepage coefficient testing device, belongs to the field of hydraulic engineering, and the IPC(international patent classification) number is E02B 1 / 00. The testing device provided by the invention comprises a operation control system, a water level sensor, a flow sensor, an on-line monitoring control device, a data acquisition system and a water pump for pumping water, wherein the water pump for pumping water is positioned under the water level sensor, and the flow sensor is connected with the water pump for pumping water through a system connection valve. In the testing process, the water pump for pumping water is started, and the groundwater on-line water level sensor and a water pump effluent water flow sensor 7 are started at the same time, then the data acquisition system automatically records water level and water flow in real time so as to obtain pumped water amount of the water pump and corresponding data on groundwater level drawdown, thereby calculating seepage coefficient and other hydrogeological parameters of a corresponding aquifer. The device disclosed by the invention is suitable for various ground water seepage coefficient tests, can accurately reflect the geohydrological conditions of the aquifer, thus improving the equipment level in the field of groundwater environment in China.

Description

1. Technical field [0001] The invention relates to a groundwater permeability coefficient testing device, which belongs to the field of water conservancy engineering, and its IPC international patent classification number is E02B 1 / 00. 2. Background technology [0002] Groundwater pumping test refers to the field pumping test in the development and utilization of groundwater to obtain related hydrogeological parameters such as permeability coefficient, hydraulic conductivity, pressure conductivity coefficient, water supply degree or elastic water release coefficient, leakage coefficient, and influence radius. At present, the groundwater pumping test has become an important technical means in the field of groundwater environment research, and has been paid more and more attention. The groundwater permeability coefficient testing device is an important device for measuring the relationship between water level and water volume. At present, domestic groundwater permeability coe...
