of which the base is set under the core.

by starting 1 and made from connected, the Piles 4 are installed by their shoes with it and between themselves four GQ 11 to a predetermined depth in the ground frames 5, each of which (not shown), after which the supports 2 are made in the form of connected with each other - are rigidly connected to the body with the help of their faces of hollow octahedral holders of the clamping type 26, prisms 6, hollow octahedral prism Uniform immersion in the swamp (not empty containers 7, equidistantly spaced) of frame 5 with body 1 with capacitance inside of prisms 6, hollow The octopus 35t 7 and the derrick (in fig. not automatic elastic chambers 8 from the hose-cauldron) are achieved by adjusting the supply of the chambers 9 and 10 to the supply and discharge of air 36 or air into the chamber 8 of capacity and water. equidistantly placed in cavities 7 of each of the four frames 5. containers 7, shoes 11 with supporting pl-chambers 8 containers 7 frames 5, tami 12, points 13, stiffening ribs whose immersion should be slowed down, 14 and bushings 15, the latter of which are reduced the water supply is 36 or even it is connected to the pins 16 from the bottom — it is completely forced out of it The hedgehogs at the ends of the piles 4 connecting the piles of 4 air at the hose 9. On the contrary, with the supports 2, additional sleeves 17 and 18, to accelerate the immersion of the desired frame 5 in this case the sleeves 18 are fixed to the top of its chamber 8 along the hose 10 - the ends of supports 2, brackets 19 with blocks of water than in chambers by 8 cabins 20 fixed on sleeves 18 top-other frames 5. Such adjustment of the loading ends of supports 2 coaxially above them, additional blocks 21 fixed on the upper surface of the body 1 under the blocks of 20 brackets 19, winches 22 mounted on the housing e 1 is eccentric 50 axis bearings 2 near the lower blocks 21, cables 23, thrown over blocks 20 and 21, fixed with their opposite ends on the housing 1 and on the winches 22 and forming lifting palisses, guiding brackets 24 located inside the square holes of the frames 25 on the outside of the piles 4, clamps 26, placed in square holes x 27,

Bringing housing 1 with frames 5 into the marsh can be performed automatically using automated control systems (not shown).

After the hull 1 and the frame 5 are immersed in the swamp so that the water level in the swamp would be two meters below the upper plane of the housing 1, the tanks 7 with the chambers 8 should be sunk below the swamp freezing boundary. Then immersed - 55 from pile 4 with the help of winches 22 and

tackles with cables 23 and blocks 20 and 21 all the way up to their plates 12 into the ground. At the same time, chambers 8 are completely filled with yut-made in the form of a hollow truncated cone and connected by pins 31 with the working end of the protective tube 29, and with the junction 4 are mounted by their shoes 11 to a predetermined depth in the ground (not shown), after which the supports 2 are rigidly They are connected to the housing with the help of clamps 26, such as a tightening clamp. Uniform immersion in the swamp (not shown) of the frame 5 with the housing 1, with the tanks 7 and the drilling tower (not shown). regulation of water supply 36 or air into the chambers of 8 tanks 7 of each of the four frames 5. To the chambers 8 of the containers 7 of the frame 5, the immersion of which should be slowed down, the flow of water 36 is reduced or even it is completely displaced from it by supplying aerated air through the hose 9. On the contrary, to accelerate the immersion of the desired frame 5 into its chamber 8 through the hose 10 is fed more water than in the chambers 8 other frames 5. This adjustment is immersed

Bringing housing 1 with frames 5 into the marsh can be performed automatically using automated control systems (not shown).

After the hull 1 and the frame 5 are submerged in the marsh so that the water level in the marsh would be two meters below the upper plane of the body 1, the tanks 7 with the chambers 8 should be sunk below the boundary of the marsh freezing. It is then immersed from pile 4 using winches 22 and

tackles with cables 23 and blocks 20 and 21 all the way up to their plates 12 into the ground. In this case, the chambers 8 are completely filled with water 36, and the horizontal position of the upper plane of the housing 1 is preserved as a result of the adjustment of the loads that sink the piles 4 all the way into the ground. If the soil under the swamp has an inclined surface or not the same hardness (viscosity), then the piles 4 will be sunk by palispasta using winches 22 to different depths.

After the completion of drilling operations and the removal of a drilling hole (not shown), water 36 is displaced from all chambers 8 by supplying compressed air to them. In this case, a lift force is created, sufficiently symmetrically arranged supports, equipped with shoes with support plates and poles, buried in the ground, while each support is made with the possibility of reciprocating motion relative to the base by means of a tread-block system installed above the base, differing from that in order to extend the functionality
