Load-carrying supporting structure of the Foundation comprises a base 1 made of thin-walled elements 2 and the anchor coating 3. Thin-walled elements 2 of the base 1 is made convex-concave in longitudinal and transverse directions and are arranged at an angle to the vertical plane. volumes with diverging and converging towards the bottom of the cells 4 of thin-walled elements 2. Convexo-concave base 1 can be made in individual cases, depending on the construction, in the form of a coil 5 is tilted in the transverse direction of the side surface diverging slope from bottom to top.When applying Foundation television and radio masts, towers and high-voltage power lines, chimneys and towers, high-rise buildings convexo-concave base 1 is made with diametrically oppositely located at the same distance from the centre (of a circle), respectively, convex 6 and concave 7 elements, and the elements 6 and the elements 7 are arranged on mutually perpendicular diameters and with the growing inclination of the lower part of the thin-walled elements, i.e. in the direction of removal of the centre of the base.For the construction of the foundations of the tower, building or mast convexo-concave base 1 made in the form of pythiaceae system with the Central cell 8 and four outer cells 9 arranged at the same distance from the centre of the base.To increase the holding torque from tipping over high towers, buildings or masts convexo-concave base is made in the plan in the form of three equidistant ellipsoidal petals 10, converging who s raising 1 thin-walled elements 2 (depending on soil) or set method indentation in the soil with subsequent backfilling of the Foundation soil, or pre-tear trench, set in her thin features grounds, covered the ground inside and outside the ground and fasten up the supporting floor.When exposed to the bearing plate cover 3 active vertical and horizontal forces supporting the floor sags and this forms a Cup deflection radius of tens of kilometers and has a value in the range 1-4 see this bowl of deflections turns of thin-walled elements in the vertical plane of the outer part in the direction opposite to the direction of the resultant active force. When turning thin-walled elements in their lower part is moved to a higher level than the upper, thereby redistributing a vertical force in a horizontal plane.As thin-walled components made convexo-concave in longitudinal and transverse directions and are arranged at an angle to a vertical plane and inclined in the transverse direction of the side surface diverging slope from bottom to top, then when the load is engaged in work not only weakened the soil located around items, and masses more durable deep layers of the soil located below the thin is more durable deep layers of the soil are involved thin-walled elements of the base. At the same time creates maximum horizontal and partly vertical reactive resistance of the soil attached to the supporting floor of the active forces.The proposed design of the bearing support structure ensures its high bearing capacity and the constancy of the spatial position in static and dynamic state irrespective of the magnitude of the vertical active and reactive forces and heave and horizontal forces (offset from temperature, slope, and others), which gives the possibility to build various structures on weak and permafrost soils and earthquake-prone areas. 1.

SUBSTANCE: method of foundation construction involves installation of embedded posts, capping beam and junction units for posts and capping beam. Preliminary soil excavation is performed at the planned foundation point to form 'trough' with horizontal bottom covered by sand filling. Then posts are embedded by pressing to a definite depth, and horizontal thermal insulation screen is laid on prepared sand filling in horizontal 'trough' bottom plane by putting the screen on embedded posts from above in the holes for posts made in the screen in advance, with further mounting of capping beam onto embedded posts by junction units. Then sleeper wall of basement element is attached to external side of embedded posts, which in turn carries vertical thermal insulation screen linked to horizontal thermal insulation screen, and water-proof key covering embedded horizontal plate of thermal insulation screen from above is placed in 'trough' onto the space formed by two screens, with thermal insulation screen covered by sand cushion and then by flagged path. Horizontal screen is covered by sand cushion at internal post side, while vertical wall of thermal insulation screen attached at external sleeper wall is rigidly connected to embedded posts.
EFFECT: enhanced operational quality, reduced cost of lodging construction.

SUBSTANCE: landslide works include rows of support bored piles, combined with foundation frame, arranged across landslide slope and drain system. In order to protect against surface landslides and mud flows, piles are cut, every two of which have, next but one, length which is less than height of landslide part of slope soil and connected above moving soil by means of foundation frames to piles reinforced with frameworks and embedded in non-shifting soils; at that, drain facilities made by means of trenchless method are connected to non-reinforced piles.

SUBSTANCE: invention relates to the field of construction, namely for the structure of free-standing foundations, erected on natural basis during construction of buildings and constructions for various purpose. Foundation under the column includes the column footing, slab part. In order to increase the carrying capacity and reduce the draft at the foot portion of foundation, protrusions are made at an angle of 120°, at that, the area of protrusions Aprotr is of (0.60-0.90) from the total area of the foot portion A. In the central portion of the foot portion of foundation there is a recess filled with rigid material with height h, not exceeding the value of the maximum permissible draft Su for this type of construction.
EFFECT: technical result consists in the increase of load-bearing capacity to the action of vertical and horizontal loads, reduction of foundation draft.
SUBSTANCE: armoured repair-evacuation machine (AREM) is additionally equipped with a quick-detachable weight-handling device, and seats are arranged in an anchor slab on the manufacturing stage. Then on a ploughshare-bulldoser of the AREM, the supports are rigidly fixed to fix weight-handling devices. The distance between the supports is arranged as equal to the distance between seats of the anchor slab. In process of anchor slab dismantling, a weight-handling mechanism is a ploughshare-bulldoser with power hydraulic cylinders of rising and lowering. The ploughshare-bulldoser is previously taken out into the position, providing for the required travel for full extraction of anchor rods as an anchor slab is being lifted. Then the weight-handling device is installed into seats of the anchor slab by one side, and by the other side it is joined with supports of the ploughshare-bulldoser, and the ploughshare-bulldoser and joined anchor slab are lifted prior to complete extraction of anchor rods from soil. The device is arranged in the form of two four-link traction rods comprising links hingedly joined to each other. Links are arranged in the form of a fork serving for fixation on an anchor slab seat, a hook serving for fixation on a support, and an eye and a lever connecting them. The form is equipped with a fastening element to connect with the anchor slab seat. The hook is arranged as capable of rigid fixation on the ploughshare-bulldoser support. The traction lever is arranged as capable of placement onto a mouldboard of the ploughshare-bulldoser when forces are applied through the eye, arising in the traction rod as the ploughshare-bulldoser moves along the arc in process of anchor slab lifting.
EFFECT: simplified dismantling of an anchor slab.
