钻孔引伸仪
borehole extensometer
Zuankong ylnshenyl钻孔引伸仪(borehole extensometer)用于测量围岩表面和内部不同深度各点对钻孔口的相对位移量的仪表。它可确定围岩位移随深度变化的关系,从而确定围岩移动范围。 钻孔引伸仪有机械式、弦式、变阻式、电容式和感应式等。常用的是机械式,它有单测点、多测点二种。测点安在同一钻孔不同深度上,并与孔壁连结在一起,岩体移动时,测点随之移动,每一测点可通过刚性拉杆、钢带或柔性钢丝伸至孔口,各测点的移动就是通过这些钢丝或拉杆进行测量的。测点与孔壁的连接可通过挤(或楔)紧,或固结材料(水泥、环氧胶)固定。 (章片)
