Description

Technical Field

[0001] This utility model relates to the field of marine mechanics simulation engineering technology, and in particular to a marine rock and soil mechanics experimental device. Background Technology

[0002] Marine geotechnical mechanics testing is used to test the mechanical properties of marine engineering structures (such as offshore wind turbine foundations and cross-sea bridge anchoring systems). It requires simulating complex working conditions such as vertical insertion and extraction of piles, application of multi-directional loads, and oblique anchoring. Due to the characteristics of marine soil and rock masses, such as high pore water pressure and strong heterogeneity, it is necessary to precisely control the loading angle, soil saturation, and boundary constraint conditions during the test to ensure that the test data can truly reflect the mechanical behavior of seabed soil and rock.

[0003] Existing experimental devices mostly use single-axis hydraulic drive, which uses a vertical hydraulic cylinder to drive the pile. The hydraulic cylinder of this type of device can only achieve loading in a single vertical direction, and cannot simulate the 15-60° variable angle loading conditions and horizontal loading conditions required for oblique anchoring. It relies on counterweights to adjust the positioning, and each position calibration takes a long time and has a large deviation in levelness. Summary of the Invention

[0004] To overcome the above shortcomings, the purpose of this utility model is to provide a marine geotechnical mechanics experimental device that can provide lateral or vertical load forces to adapt to different simulation scenarios, especially for simulating horizontal loading conditions; the lifting mechanism can drive the servo electric cylinder to lift in the axial direction, and the moving mechanism can drive the servo electric cylinder to move in the X and Y axis directions, and the movement is stable and not easy to shake, so as to provide stable and efficient load force output.

[0005] The technical solution of this utility model to solve its technical problem is:

A second slider is connected to the lower end of the fixed rod, and a second guide rail is connected to the upper surface of the crossbeam, allowing the fixed rod to move on the second guide rail via the second slider. The lifting mechanism is connected to both the fixed rod and the servo electric cylinder.

[0008] As a further improvement of this utility model, the front end face of the crossbeam is connected to a fifth guide rail, the fixed rod is connected to a fifth slider, and the fifth slider is slidably connected to the fifth guide rail.
