Pile soil interface shear simulation tester of opened concrete pipe pile
The invention belongs to the technical field of testing equipment of buildings and relates to a pile soil interface shear simulation tester of an opened concrete pipe pile, wherein a screw rod is vertically installed on an operation platform, an upper end and a lower end of a spring are respectively fixed on a dismountable spring upper fixation plate and a dismountable spring lower fixation plate, a testing soil sample is placed inside an upper shear box, the top part is flush with the dismountable spring lower fixation plate, and the left side face of the upper shear box is rigidly connected to the operation platform; a concrete sample is placed inside the lower shear box, a slide track is disposed on the operation platform, the operation platform is connected to the lower shear box by a roller, and a numerical control motor is rigidly connected to the lower shear box; and a vertical displacement sensor is installed on the dismountable spring lower fixation plate, a horizontal displacement sensor is installed between the upper shear box and the lower shear box, and a load sensor is placed on a first steel rod on the left side of the upper shear box. The pile soil interface shear simulation tester of the opened concrete pipe pile has a simple structure, is operated conveniently, has scientific theories, obtains accurate testing results, has low cost and is applied widely.
