Constant Head Permeability Apparatus

Application: 

The inner diameter is φ100+0.22mm. It can be used to measure the sand soil and the non-cohesive soil containing a small amount of gravel under the normal head.

The instrument is mainly composed of a water-permeable component and a compacted part. The water seepage component is composed of a barrel body, a water seepage plate, a scale plate, a pressure measuring tube, etc., and three pressure measuring tubes are arranged on the scale plate, the spacing is 100±0.44 mm, and the reading of the water level can be scaled by the scale plate mounted on the cylinder. Read and put the copper wire cloth in the pressure pipe joint to prevent the fine sand from flowing out with the water during the test. There is a drainage hole in the lower part of the water seepage cylinder, and the sewage can be released by loosening the bolt. The compacted part is provided with a wooden hammer to compact the sample.
