GEODETIC MONITORING OF TONGUE AND GROOVE JOINT FENCE OF THE PIT
Tongue and groove fence represent wells which are drilled according to the project, they are lined with pipes that create a system of holding from the collapse of the walls of the pit. Typically, the dowel fence pits set temporarily to avoid collapse of soil during construction. Tongue and groove fence pits are important in the construction to enhance the bearing capacity of the pile and prevent the shedding of the soil.
the Measurement of the vertical and horizontal displacement of pile our employees produce modern high-precision total station Leica TCR 1201. For geodetic monitoring "wall in the ground" or pile on the perimeter (step 6-15 meters) walling of the pit are laid metal corners. These parts are installed geodetic marks in the form of reflective plates. In the future, for planned travel brands produced multiple linear and angular measurements on targets outside the zone of influence of strain and film reflectors, which are installed on the test point. After this are repeated measurements with the goal of determining standard displacement models. The results of observations are processed using geophysical software. The data obtained are recorded in the statement of initial total station brands
- standard displacement of pile or the "wall in the ground".
- Altitude offset of the enclosing structure of the pit.
- definition of the slope of the sheet piling.
