Abstract
The present invention relates to a seepage erosion test system designed to evaluate soil erosion under controlled conditions. The system includes an acrylic rectangular pipe featuring a circular opening at its lower end. Attached to this is a soil sample pushing sub-device that encompasses a cylindrical sample tube, a piston, and four pore pressure gauges. The piston, which moves vertically within the tube. Additionally, the system incorporates a graduated cylinder pressurizing sub-device consisting of a graduated cylinder for water, a push plate, and a second pushing device for hydraulic pressurization. Water flow is regulated through a hose connected at one end to the piston and equipped with a valve for control. An air release valve and an air pressure sensor are also included for monitoring pressurization. The setup is completed with a three-way valve connected to the pipe, facilitating precise control of water flow and pressure during testing.
