Testing device for measuring water and soil pressure during pile sinking of open tubular pile and mounting method
The invention relates to a test device for measuring water and soil pressure during pile sinking of an open tubular pile, which comprises an outer pipe, an inner pipe, a wire hole, a screw, a sensor hole, a sleeve, a soil pressure sensor, a pore water pressure sensor, a soil pressure sensor wire and a pore water pressure sensor wire, the outer pipe and the inner pipe are coaxially and fixedly arranged, and a gap is reserved between the inner part of the outer pipe wall and the outer part of the inner pipe wall; the inner pipe wall and the outer pipe wall are each provided with a plurality of sensor holes at intervals in the radial direction, coaxial wire holes are formed in the inner pipe wall and the outer pipe wall in the radial direction, the sensor holes are arranged in a staggered mode, a sleeve is embedded in each sensor hole, and each sleeve is sleeved with a soil pressure sensor and/or a pore water pressure sensor. A plurality of wires are arranged in gaps outside the inner pipe wall and inside the outer pipe wall and penetrate out of the outer pipe through the wire holes. The device is simple in overall structure, economical, practical, easy to manufacture and install and suitable for testing the soil pressure of the inner wall and the outer wall and the pore water pressure during pile sinking of the open tubular pile in an indoor model test.
本发明涉及一种开口管桩沉桩时水土压力测量的试验装置，包括外管、内管、导线孔、螺丝、传感器孔、套筒、土压力传感器、孔隙水压力传感器、土压力传感器导线、孔隙水压力传感器导线，外管和内管同轴固装，外管壁内和内管壁外之间留有空隙，在内管壁以及外管壁分别径向间隔设置有若干传感器孔，在内管壁以及外管壁的径向设置有一同轴的导线孔，传感器孔错落设置且每个传感器孔均嵌装有一套筒，每个套筒套装一土压力传感器和/或孔隙水压力传感器，在内管壁外和外管壁内的空隙中布设若干导线，从导线孔穿出外管外。本装置整体结构简洁，经济实用，易于制作和安装，适用于在室内模型试验中测试开口管桩沉桩时的内外壁土压力和孔隙水压力。
