Method of arranging driven pile

FIELD: construction.

SUBSTANCE: method of arranging driven pile, in which a well informed by dipping into the ground of the casing string with a closed lower end to the spreading base layer of soil, fill the casing string with tight or loose material, remove the casing string, generate a broadened base in support of the base layer of soil, immerse the reinforced concrete pile with the penetration of its end into the broadened base. To form the well, a casing string with a self-opening tip is used, the immersion of which is carried out with penetration into the spreading base layer of soil. Filling the casing string is first carried out with a rigid ground material or a rigid concrete mix, and then with loose or rigid ground material. The non-extractable shell-tube, equipped with a rim-nozzle on its lower end, with its penetration into the bearing layer of soil, is penetrated into the ground outside the casing string coaxially with it. When removing the casing string with a self-extracting tip, the shell-tube is simultaneously filled with filling material located in the casing string, followed by immersion of the reinforced concrete pile into the filled shell-tube up and forming a broadened base and enlarged compacted area in base layer of soil in and with increasing density of filling material within the lateral surface of the submerged pile.

EFFECT: increased bearing capacity of pile and pile foundation, reliability of its construction, expansion of the field of application on ground conditions, increased efficiency as a whole.

FIELD: building, particularly to erect foundation bases in permafrost ground.

SUBSTANCE: method for tubular pile driving in permafrost ground involves drilling hole; installing pile in the hole and leaving it as it is inside the hole up to thermal permafrost ground regime recovery. To install pile in the ground inventive insert having diameter smaller than hole diameter in lowered in hole along central hole axis. Space between the insert and hole wall is filled with loose ground. Then the pile having inner diameter practically equal to outer diameter of the insert and opened lower end is driven in the loose ground. After that the insert is removed from hole. Other variants of pile driving are also disclosed.

EFFECT: increased building and assembly job efficiency due to decreased time of pile freezing in permafrost ground and improved load-bearing capacity of piles.

FIELD: building, particularly cast-in-place building units, namely support structures.

SUBSTANCE: reinforced concrete column is formed in retained formwork and consists of upper support part and lower foundation part. Column includes reinforcement frame grouted with concrete mix and embedded members arranged in upper column part. Upper part of frame is located in retained formwork. Embedded members are in level with foundation slab marks and with flooring panel marks. Embedded members are formed as closed contours with stiffening ribs. Column is built in single- or multi-slot hollow. Projection of geometric retained formwork cross-section center coincides with that of lower reinforcement frame part. Arms of lower reinforcement form part extending in Y-axis direction are sized in accordance with given mathematical relation. Method of column erection involves forming single- or multi-slot hollow; producing reinforcement form with embedded members; forming retained formwork; installing above components; vertically placing the reinforcement frame in hollow so that frame is spaced a distance from hollow bottom; vertically adjusting and fixing upper column part to prevent transversal displacement thereof; grouting lower column part in bottom-top direction; grouting inner retained formwork area of upper column part. Hollow has dimensions measured in Y-axis direction determined from given relation.

EFFECT: possibility of simultaneous building erection in upward and downward directions relative ground level.
