Device and method for installing pore water pressure gauge in soft soil layer
The invention discloses a device and method for installing a pore water pressure gauge in a soft soil layer, and the method comprises the steps: installing the pore water pressure gauge in an installation cylinder, carrying out the assembly, and inserting an installation rod into the installation cylinder; the mounting cylinder is put down into a drilled burying drill hole along with the mounting rod, a drilling machine is used for applying downward pressure to the mounting rod, and the mounting cylinder is pressed into a soft soil layer at the bottom of the hole until the mounting cylinder reaches the burying depth of the monitoring point on the lowermost side; the mounting rope is fixed to the ground, meanwhile, the mounting rod is lifted section by section, the mounting cylinder and the mounting rod are automatically separated, and the mounting cylinder is mounted to the preset monitoring depth; and a hole sealing soil column is lowered between the adjacent pore water pressure gauges, soil bodies between the upper and lower adjacent monitoring points of the drill hole are sealed and tamped in a layered mode, and then the drill hole is backfilled. The device is convenient to install and operate, can be suitable for pore water pressure monitoring when the lower soil layer is a soft soil layer, can effectively isolate communication of adjacent pore water pressure gauges, and is high in monitoring accuracy.
本发明公开了一种用于软弱土层中安装孔隙水压力计的装置及方法，包括将孔隙水压力计安装在安装筒内并进行组装，安装杆插入安装筒中；将安装筒随安装杆下放至钻探好的埋设钻孔中，用钻机对安装杆施加下压力，将安装筒压入孔底的软弱土层中，直至到达最下侧监测点埋置深度；将安装绳固定在地面，同时逐节上提安装杆，使安装筒与安装杆自动分离，安装筒被安装至预定监测深度；将封孔土柱下放到相邻孔隙水压力计之间，再将钻孔上下相邻监测点之间的土体分层封堵捣实，进而再对钻孔进行回填。本发明的装置安装和操作便捷，能适用于下部土层为软弱土层的孔隙水压力监测，可以有效隔绝相邻孔隙水压力计的连通，监测准确性高。
