Centrifugal field slope pile driving system

Abstract

The invention discloses a centrifugal field slope pile driving system. An open system architecture which is low in cost and easily implemented is provided by combining the structural characteristics of a geo-centrifuge. The system comprises a pile storage mechanism, a moving mechanism, a pile pressing mechanism and a clamping manipulator; and through the system, real-time pile driving reinforcement in a slope centrifugal model test process is realized, and the pile driving position and the pile driving depth can be accurately controlled. The system also has the advantages that: (1) the system is strong in reliability and low in cost; (2) because the equipment and a model box are mutually independent, the limitation of narrow internal idle size after sample preparation in the test model box is avoided, and the system is suitable for the sample preparation modes of various models; (3) the principle of the equipment is simple, the driven piles cover the whole slope, and pile driving rate and pile driving depth of different positions are realized; (4) the system is convenient to control, and can be well used for real-time pile driving reinforcement of a slope; (5) the system has wide applicability, and can be applied to the slopes of multiple soil properties such as clay, silt and the like; and (6) the system is easy to reform, and new application can be developed according to the original system architecture.

Description

technical field [0001] The invention belongs to the technical field of slope geotechnical centrifugal models, and in particular relates to a centrifugal field slope pile entry system. Background technique [0002] Anti-slide piles are a common reinforcement structure in slope treatment engineering, so the research on the reinforcement law and mechanism of slope anti-slide piles is of great significance for optimizing the reinforcement method. The centrifugal model test can realize the same stress and strain and similar deformation between the model and the prototype, and has been widely used in problems such as slope stability. Many scholars have also conducted research on the reinforcement of slope anti-slide piles. Anti-slide piles are arranged at different positions and depths of the slope, and are generally driven vertically. However, in the existing centrifugal model tests, the piles are generally inserted during sample preparation, which cannot consider the influence...

Problems solved by technology

However, in the existing centrifugal model tests, the piles are generally inserted during sample preparation, and the influence of the pile entry process on the deformation of the slope cannot be considered, and the actual pile entry conditions cannot be simulated.
