Soft soil layer foundation model preparation equipment capable of reducing moving resistance and method

Abstract

The invention discloses soft soil layer foundation model preparation equipment capable of reducing moving resistance in the technical field of foundation model preparation equipment, the soft soil layer foundation model preparation equipment comprises a model box and an angle adjusting assembly, movable rods are inserted into the outer wall of the top of the angle adjusting assembly in a penetrating mode, and a soil penetrating plate is arranged in an inner cavity of the model box; the bottom ends of the two sets of movable rods are hinged to the outer walls of the left side and the right sideof a soil penetrating plate correspondingly, the soil penetrating plate comprises an installation frame hinged to the movable rods, and soil permeable layers are movably installed on the front side and the rear side of an inner cavity of the installation frame correspondingly. According to the equipment, a telescopic rod is moved out of the angle adjusting assembly, and a winding roller rotates through contraction of a clockwork spring; The soil permeable layers are pulled into the inner cavity of a storage groove, and the contact area of the soil penetrating plate and soil is reduced, so that the resistance of the soil on the soil penetrating plate during up-down movement or rotation is reduced, and the pressure applied to the soil during adjustment of the soil penetrating plate is alsoreduced; and the influence on the test accuracy of the model box due to compaction of soft soil in the model box in the process of adjusting the soil penetrating plate is avoided.

Problems solved by technology

[0002] In transportation construction, it is necessary to use the foundation model to conduct theoretical simulation tests on the foundation conditions encountered in the construction process to ensure the safety of the actual construction. The measurement and design of the inclined soft soil foundation with different thicknesses and soft soil foundation models with different thicknesses is usually achieved by adjusting the angle and height of the permeable soil plate in the model box. However, the existing permeable soil plate is located in the soft soil of the model box. In the layer, when the permeable soil plate moves up and down or rotates to adjust, the upper and lower side walls of the permeable soil plate will be in contact with the soft soil layer. The contact area of ​​the permeable plate will be affected by the resistance provided by the soft soil layer when it moves up and down or rotates, which will affect the adjustment of the movement of the permeable plate, and the up and down movement of the permeable plate will also exert pressure on the soft soil layer, which will easily cause the soft soil layer to be damaged. Therefore, we propose a soft soil foundation model preparation equipment and method that can reduce the movement resistance
