METHOD FOR DIAGNOSTICS OF CONVERGENCE OF WALLS OF AUGERING WELLS

摘要

Method for diagnostics of convergence of walls of augering wells includes penetration of augering well, placement and fixation there of deep marks at whole stem of well, implementation of measurements of deformation of rocks in rock mass and plotting graph of convergence of well walls. Placement of pneumatic cable with elastic measuring elements fixed on it is carried out in cavity of augering well with following injection of compressed air there to pressure needed for provision of tight contact between measuring chambers and walls of the well and implementation of observations of pressure change in measuring chambers by means of manometers.
