SUBSTANCE: method for making well for rolled-screw pile including drilling of conventionally cylindrical well. Roller unit and step accessory are connected to auger, device rotation is actuated for thread rolling, roller unit is brought into well, and thread making is started with the help of three rollers with various diametres and thicknesses in the form of truncated cone each, which are serially rolled one after another, and soil is impressed into well wall with angle of thread inclination between plane, where large wheel of each roller is located, and axis of roller unit rotation, making 76 degrees. Master roller executes primary rolling of thread, then intermediate roller of larger diametre and thickness expands groove, increasing thread dimension, and shaping roller of larger size completes soil compaction into well wall and thread rolling. Pitch, which provides for step accessory on auger per single complete rotation of shaping roller equal to 360 degrees makes 0.67 d, where d is diametre of roller unit pipe, and thread pitch corresponds to pitch of single turn of auger blade. Step accessory operates only in process of thread rolling together with rolling unit, and thus thread is rolled for the whole depth of well, reverse rotation is started, and roller unit is brought upwards along shaped thread, afterwards well is inspected and concreted. Device for method realisation comprises auger for drilling of conventionally cylindrical well, device for thread rolling made of roller unit, auger and step accessory. Roller unit includes steel pipe with diametre d with slots for rollers, steel bushings for axles of rollers, master roller with diametre of 0.52 d, intermediate roller with diametre of 0.71 d, shaping roller with diametre of 0.83 d, cover with tail, bottom. All three rollers are arranged as steel and are shaped as truncated cone, and straight line that coincides with diametre line of large wheel in each roller, crossing axis of roller unit rotation, is perpendicular to generatrix of pipe cylindrical surface in point of their crossing, and plane of each roller fit, i.e. plane of roller unit rotation axis crossing with point of crossing of roller rotation axis and large wheel of roller are at the angle of 120 degrees to similar plane of fit of each of two rollers.

SUBSTANCE: method of installing tubular pile in permanently frozen earth involves rotation of pile and its simultaneous vertical movement under influence of pressing axial load applied to the pile. At that speed of vertical pile movement Vm, value of pressing axial load Pt and angular speed of pile rotation ω are controlled using a nomogram built in logarithmic coordinate system wherein along x-axis there marked are magnitudes of the value (athth) that comprises the ratio of thermal conductivity of thawed earth ath to thickness of thawed earth seam under pile edge δth, and along y-axis there marked are values of speed of vertical pile movement Vm. Nomogram consists of two families of Vm-vs-(athth) curves based on calculations of thermal, mechanical and hydrodynamic processes when installing the pile. The above nomogram provides the possibility of choosing the speed of vertical pile movement Vm, depending on pile size and specific earth properties, when Pt and ω are available, as well as the possibility of choosing pressing axial load Pt and angular speed of pile rotation ω when Vm and ath, δth are available.
