Abstract

The invention provides a varying water head generation device. The varying water head generation device is characterized by comprising a supporting frame, a cable, a water tank, a fixed pulley, a flow meter, a water pressure sensor, an elevation sensor, a motor, a rotary table and a lock catch, wherein one water tank capable of being hoisted up and down is arranged in the middle of the supporting frame; the water tank is provided with scales; a water overflowing hole is formed in a side wall at the upper part of the water tank; a water inlet is formed in the side wall at the lower part of the water tank; a water outlet pipe, which extends out of the water tank, is arranged at the bottom of the water tank; the water pressure sensor and the flow meter are arranged on the water outlet pipe; the elevation sensor is arranged at the bottom of the outer side of the water tank. The varying water head generation device can be used for acquiring different water head data and is convenient for testing and researching.

Description

technical field [0001] The invention belongs to the field of seepage tests, and relates to a water head generating device, in particular to a water head generating device whose water head can be changed at any time. Background technique [0002] Permeability test is divided into two categories: indoor test and field measurement test. There are many types of instruments and test methods for measuring the permeability coefficient k in the laboratory. According to whether the water head changes, it can be divided into constant water head test and variable water head test. At the same time, constant water head test and variable water head test will also be involved in the study of other subjects such as the mechanical properties of soil. The constant water head test is to keep the water head constant during the whole test process, so that the water head difference is also constant. The variable head test is that the water head difference changes with time during the test process...
