AUTOMATIC EXTRUSION SYSTEM OF SOIL SAMPLES AND AUTOMATIC FLOW CONTROL SYSTEM FOR SCOUR RATE TEST APPARATUS

摘要

An automatic extrusion system of soil samples and an automatic flow control system for a scour rate test apparatus are provided to quantitatively measure the scour rate of the soil samples through an artificial flow. An apparatus includes a sample rise unit(100) inputting samples into a watering pipe, a flow control unit(200) controlling a flow, and a control unit(300) for controlling an operation of the flow control unit. The sample rise unit includes a support(110) installed at a bottom, a tube fixing plate fixing a sampling tube, a fixing plate elevating unit(130) installed at the support to elevate the tube fixing plate, a piston(140) for elevating the samples in the sampling tube and a piston elevating unit(150) for elevating the piston.
