FIELD: construction.SUBSTANCE: invention relates to fortification and can be used as shaft structure of increased security for objects, buried in soil. Structure comprises well shaft, made in form of truncated cone, which upper base is input into mine, and lower base is base of shaft, wherein well shaft is divided into four equal in height tubing connected with "interference” with help of appropriate collars and grooves, protective device, shock absorber and head with equipment.EFFECT: each tubing is equipped with circular belt stability, wherein larger base of belt is welded to shaft and smaller is to corresponding lateral vibrations damper symmetry to axis passing through middle of each tubing, wherein dimensions of stability belts and dampers of lateral vibrations are matched with height of tubing, wherein all dampers of lateral oscillations are located at equal distance from shaft wall axis.1 cl, 2 dwg |
