MEASURING APPARATUS FOR SETTLMENT OF GROUND SURFACE

摘要

PURPOSE: A device for measuring the sinking level of the ground surface is provided to enable a measurement operation to be automatically performed since a device for measuring the relative behaviors of a core pile and a sinking plate is simply mounted. CONSTITUTION: A device for measuring the sinking level of the ground surface comprises a core pile(100), a sinking plate(200), a protective tube(300) and a measuring unit(400). The lower end of the core pile is fixed to the immovable layer(1) of the ground and the upper end is exposed onto the ground surface. The through-hole(210) of the core pile is formed on the center of the sinking plate and behaves with the ground surface(3). The protective tube is installed on the upper part of the through-hole of the sinking plate to protect the core pile. The measuring unit measures the upper/lower relative behavior of the sinking plate to the core pile according to the sinking of a sinking layer(2).
