Model test device and test method for studying pile sinking of expanded pile
The invention discloses a model test device and method for studying pile sinking of an expanded pile. The test device comprises a model box, a loading device, a force transmission frame, a tension and compression sensor, a positioning sleeve, a model pipe pile, a vertical guide device and a PVC pipe. The test method comprises the following steps: manufacturing a model pipe pile; filling test soil and forming holes in the soil; the hole is filled with a body expanding material; positioning the model pipe pile; pile sinking and data monitoring; and sorting data and a test site. According to the assembly type pile sinking model test device, the test method is designed according to the construction technology in engineering practice, and the assembly type pile sinking model test device has great scientific research value and economic benefits for studying the pile sinking resistance in the pile sinking process of the expanded pile and exploring measures for reducing the resistance of the expanded pile. By means of the testing device and method, the pile sinking resistance, the pile end resistance and the pile side friction resistance of the implanted expanded pile under various working conditions can be explored, observation and analysis are conducted through obtained data, and a theoretical basis is provided for relevant research of the follow-up expanded pile sinking process.
