The TST-70 soil infiltration instrument

Modelled Kima type penetration instrument manufacturer, the size of the diameter of theφ100+0.22mm can be measured in sand soil and containing a small amount of gravel for non cohesive soil in constant head permeability test under. The instrument is mainly composed of porous parts and compaction part. Seepage is composed of cylinder body, the seepage plate, a scale plate, pressure pipe, on the scale plate is provided with three pressure tube, the spacing is 100± 0.44mm, water level measurement can be installed in the tube on the scale plate scale readout, pressure pipe joint is equipped with copper wire cloth to prevent fine sand in test with water outflow. Seepage tank is provided with a drainage hole, loosen the bolts can be discharged sewage. Compaction part with wooden hammer, to compaction sample. The equipment design and manufacture with （GB9357-77） standard, accord with" specification of soil test" （ SL237-1999）" test methods of soils for Highway Engineering" （ T0129-93） in sand soil and containing a small amount of gravel for non cohesive soil in constant head permeability test under
