Pile-soil contact surface shearing mechanical property testing device
The invention relates to the technical field of civil engineering, in particular to a pile-soil contact surface shearing mechanical property testing device which comprises a top plate, a supporting disc and a chassis. A membrane box is embedded between the supporting disc and the chassis, and the membrane box comprises a rubber membrane cylinder, a bottom supporting plate and a cover plate. The bottom supporting plate is coaxially embedded in the middle of the bottom plate and arranged at the lower end of the rubber film cylinder, and the cover plate is used for sealing an upper end opening ofthe rubber film cylinder. A vertical loading device is arranged in the middle of the top plate and is used for applying vertical pressure to the pile. A set of tightening belts are evenly distributedon the periphery of the rubber film cylinder, and each tightening belt is in an arc shape and tangent to the outer circle of the rubber film cylinder. Different experimental comparisons can be achieved, by controlling the displacement stroke of each telescopic rod, when the strokes of the telescopic rods are the same, the same horizontal pressure is correspondingly applied to the pile in all directions, and when the strokes are different, different states of different side pressures are achieved, and the device is flexible, changeable and suitable for different experimental requirements.
本发明涉及土木工程技术领域，具体的说是一种桩土接触面剪切力学特性测试装置，包括顶板、支撑盘和底盘，在支撑盘与底盘之间嵌入安装膜箱，膜箱包括橡胶膜筒、底托板和盖板；底托板同轴嵌入安装在底板中部，底托板设置在橡胶膜筒下端，盖板用于密封橡胶膜筒的上端口；顶板中部设有竖向加载装置，竖向加载装置用于对桩柱施加竖向压力；在橡胶膜筒外周均匀分布一组收紧带，每个收紧带呈弧形并与橡胶膜筒外圆相切。本发明能够实现不同的实验对比，通过控制每个伸缩杆的位移行程，在伸缩杆行程相同时，则相应的各个方向对桩柱施加一样大小的水平压力，在行程不同时，则实现不同侧压力不同的状态，灵活多变，适应不同的实验要求。
