Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] An integrated groundwater hydraulic gradient measuring instrument, comprising: a hollow tube, a gap on both sides of the hollow tube, a pressure sensor 11 placed at the bottom of the hollow tube and the gap, recording the head value measured by the pressure sensor 11 The inspection instrument 1 is controlled, and the pressure sensor 11 at the control gap extends or retracts the telescopic assembly of the gap; the pressure sensor 11 and the inspection instrument 1 are connected by a wire 2. In order to fix the electric push rod 6 and ensure that the pressure sensor at the notch can only telescopically move, the hollow tube is provided with a fixing bracket 5 for fixing the electric push rod 6; as a preference, the hollow tube is a steel pipe.

[0018] In order to realize the extension gap and retraction gap of the pressure sensor 11, the ...

Abstract

The invention discloses an integrated groundwater hydraulic gradient measuring device. The device comprises a hollow pipe, gaps arranged at two sides of the hollow pipe, pressure sensors arranged at the bottom of the hollow pipe and the gaps, a tour inspection device for recording head values measured by the pressure sensors, and telescoping assemblies for controlling the pressure sensors at the gaps to stretch out of or retract from the gaps. The groundwater hydraulic gradient measuring device is advantaged by simple operation, automatic data obtaining, and accurate results, the groundwater head can be accurately measured and the real seepage velocity and the direction of groundwater can be calculated via the design of a three-probe pressure sensor system, the telescoping of the pressure sensors can be controlled by the telescoping assemblies so that the pressure sensors can be arranged at designated positions, and the measuring accuracy is improved.

Description

technical field [0001] A measuring instrument, particularly a groundwater hydraulic gradient measuring instrument. Background technique [0002] The study of the interaction between surface water and groundwater has always been a hotspot in water cycle and water resources research. In surface water-groundwater interaction studies, it is often necessary to measure groundwater hydraulic gradients to determine the magnitude and direction of groundwater seepage velocity. At present, the commonly used devices for measuring the hydraulic gradient of groundwater can only measure the vertical hydraulic gradient, and cannot obtain the size and direction of the real groundwater seepage velocity, and have the disadvantages of complicated operation and long time consumption. The integrated groundwater hydraulic gradiometer not only has the advantages of simple operation and automatic data acquisition, but also the magnitude and direction of groundwater seepage velocity can be accuratel...
