Shearing experiment device for pile-soil contact surface of drainage pile
The invention discloses a drainage pile soil contact surface shearing experiment device which comprises a model column, a supporting system, a pressure control system, a water pumping and draining system and a measuring system, the model column comprises a baffle and a bottom plate, the supporting system comprises four supporting columns arranged on the lower side of the bottom plate, and the pressure control system comprises a plurality of pressure control units. Each pressure control unit comprises a lever, a hook weight, an inhaul cable, a fixed pulley, a connecting cylinder, a cover plate, a fixing frame and a jack, the pumping and drainage system comprises a plurality of drainage holes, permeable cloth, an exhaust pipe and a vacuum pump, and the measuring system comprises a plurality of dial indicators, a plurality of soil pressure gauges, a plurality of pressure sensors and a plurality of pore pressure gauges. The experimental device can simulate the conditions of pile-soil contact surfaces under different depths, different consolidation degrees and different vacuum degrees, can measure the soil pressure, relative displacement and side friction resistance of the contact surfaces of static drill rooted drainage piles or precast piles and cement soil or clay or sandy soil, and provides important support for research on the bearing characteristics of pile foundations in coastal areas.
本发明公开了一种排水桩桩土接触面剪切实验装置，包括模型柱、支撑系统、压力控制系统、抽排水系统和测量系统，模型柱包括挡板和底板，支撑系统包括设于底板的下侧的四个支撑柱，压力控制系统包括若干组压力控制单元，每组压力控制单元包括杠杆、钩码、拉索、定滑轮、连接筒、盖板、固定架和千斤顶，抽排水系统包括多个排水孔、透水布、抽气管、真空泵，测量系统包括若干百分表、若干土压力计、若干压力传感器和若干孔压计。该实验装置可模拟不同深度、不同固结度、不同真空度下桩土接触面情况，可测定静钻根植排水桩或预制桩与水泥土或黏土或砂土接触面的土压力、相对位移和侧摩阻力，为沿海地区桩基承载特性研究提供重要的支撑。
